The management of vesicoureteral reflux with neurogenic bladder due to spina bifida

Thirteen cases (20 ureters) of vesicoureteral reflux (VUR) associated with neurogenic bladder, treated with anti-reflux operation are reviewed. Twelve of the 13 cases had meningomyelocele and 1 had spina bifida occulta as an underlying disease. The type of neurogenic bladder was hypoactive detrusor-active sphincter in 11 patients and hypoactive detrusor-hypoactive sphincter in 2 patients. They were treated with an anti-reflux operation, 2 ureters by Politano-Leadbetter method and 18 ureters by Cohen method. The results were successful (success rate 85.0%). Therefore, we concluded that in neurogenic bladder patients especially with the hypoactive detrusor-active sphincter, the cause of their renal deterioration is mostly VUR. Thus we should examine such patients for VUR. On the other hand, when the renal deterioration of VUR patients cannot be improved by conservative treatment for example clean intermittent catheterization or indwelling catheter, we should perform an anti-reflux operation.     

Outcomes of lower urinary and bowel function in meningomyelocele patients with augmentation enterocystoplasty

OBJECTIVES: We evaluated the outcomes of augmentation ileocystoplasty in video-urodynamics (V-UDS) and questionnaires related to bowel and urinary function.Methods:In 22 meningomyelocele (MMC) patients (11 male and 11 female, a mean age at surgery 14.4 years) who underwent augmentation ileocystoplasties, V-UDS was performed before and at a median of 15 months (6-120 months) after the surgery and the questionnaires were answered at a median of 7.1 years (1.1-14.5 years) after surgery. RESULTS: Concomitant procedures of urethral sling in four, cecostomy in four and ureteral reimplantation in two were performed at augmentation ileocystoplasty. V-UDS showed a significant improvement after the surgery in bladder capacity, bladder compliance and detrusor overactivity. Vesicoureteral reflux (VUR) disappeared after the surgery in 16 of 19 ureters with VUR. Although questionnaire for urinary condition using International Consultation on Incontinence Questionnaire-Short Form demonstrated that 80% of patients were completely free from urinary incontinence after surgery, more than a half of patients had persistent or deteriorated bowel function such as urgency of bowel movement and fecal incontinence in questionnaires for bowel function. Even with complaints in bowel function, more than 80% of MMC patients had a high level of satisfaction with augmentation enterocystoplasty in overall quality of life (QOL). CONCLUSIONS: Benefits of augmentation ileocystoplasty were maintained in urodynamic parameters as well as urinary continence. Although augmentation ileocystoplasty generally provides high QOL for MMC patients refractory to conservative therapies, an advance of fecal management can make MMC patients' QOL superior to a current state.     

Urinary undiversion by conversion of the incontinent ileovesicostomy to augmentation ileocystoplasty in spinal cord injured patients

Context: Spinal cord injury (SCI) patients with neurogenic bladder and the inability to self-catheterize may require incontinent diversion to provide low-pressure drainage while avoiding the use of indwelling catheters. We demonstrate that in patients with significant functional improvement, the ileovesicostomy can be a reversible form of diversion, with simultaneous bladder augmentation using the same segment of ileum utilized for the ileovesicostomy. Multidisciplinary management should be utilized to assure mastery of intermittent catheterization before urinary undiversion. This technique allows for transition to a regimen of intermittent self-catheterization with excellent functional and urodynamic outcomes.Design: Case Series.Setting: Tertiary care hospital, Philadelphia, Pennsylvania.Participants: Three individuals with an SCI.Interventions: Conversion of bladder management from an incontinent ileovesicostomy to an augmentation ileocystoplasty, with intermittent catheterization.Outcome Measures: Ability to regain urinary continence with preservation of renal function as determined by serum creatinine and renal ultrasound.Results: Three SCI patients who had an incontinent ileovesicostomy developed sufficient functional improvement to intermittently self-catheterize reliably and underwent conversion of ileovesicostomy to ileocystoplasty. For each, the ileovesicostomy channel was taken down and detubularized, then used to create an ileal patch for augmentation ileocystoplasty. Intermittent catheterization was then used for periodic bladder drainage. All achieved large capacity, low-pressure bladders with complete continence and stable creatinine.Conclusion: In motivated SCI patients, it is possible to regain continence by converting the ileovesicostomy into augmentation ileocystoplasty, avoiding the disadvantages of a urostomy. A multidisciplinary collaborative approach facilitates the optimal rehabilitation of SCI individuals.     

Fecal and urinary continence after ileal cecal cystoplasty for the neurogenic bladder

PURPOSE: In patients with a neurogenic bladder augmentation with the ileal cecal segment has generally been disregarded as an option due to concerns regarding fecal incontinence. We report our results using a hemi-Indiana pouch bladder augmentation for neurogenic bladder. MATERIALS AND METHODS: A review of 63 patients with neurogenic bladder dysfunction treated with a hemi-Indiana pouch bladder augmentation was performed. None of the patients had fecal incontinence before surgery. RESULTS: Median followup interval was 6 years (range 1 to 10). Etiology of the neurogenic bladder was spinal cord injury in 42 patients (66%), myelodysplasia in 18 (29%) and sacral agenesis in 3 (5%). One patient (1.5%) died immediately postoperatively from a pulmonary embolus. Of the remaining 62 patients, urinary continence was achieved in 54 (87%) and 8 were incontinent per the abdominal stoma. All 8 patients were treated with Contigen injections into the stoma and 4 (50%) became continent. The 4 patients with persistent urinary incontinence became continent after open surgical revision. Postoperatively, fecal continence was improved in 14 patients (23%), unchanged in 46 (74%) and worse in 2 (3%). In 2 patients with deterioration in bowel function stool frequency and fecal soilage increased in conjunction with antibiotic usage. No patient had chronic fecal incontinence. CONCLUSIONS: In select patients with neurogenic bladder dysfunction ileal cecal bladder augmentation with a continent tapered ileal limb results in a 100% incidence of urinary continence with minimal alterations in fecal continence.     

Long-term outcome of monotherapy by Cohen ureterocystoneostomy for vesicoureteral reflux in spina bifida patients]

BACKGROUND: The conventional surgical treatment for vesioureteral reflux (VUR) is spina bifida patients is ureterocystoneostomy. Various newer therapies, including augmentation enterocystoplasty and minimally invasive subureteral collagen injection, have been introduced. However, all of these procedures have specific advantages and disadvantages, and no guidelines for deciding on the surgical treatment of VUR in spina bifida patients have yet been established. In this study, the long-term outcome of the Cohen procedure, a method of ureterocystoneostomy, was examined. PATIENTS AND METHODS: Among spina bifida patients in whom VUR was treated by the Cohen procedure alone from 1984 to 1989, 27 patients who could be followed up for 5 years or longer were enrolled in the study (11 males and 16 females, with a mean age of 13.4 years at surgery). In principle, they were followed up using annual cystography, excretory urography, and blood and urine tests. At the final assessment, they were examined for the presence at VUR and for morphological abnormalities of the urinary tract. Their renal function was also assessed. They were followed for 6 to 13 years (mean: 8.9 years), and the mean age at final assessment was 22.2 years. RESULTS: Among 42 ureters in the 27 patients examined, 38 ureters (90.5%) in 22 patients (81.5%) did not have VUR postoperatively. Four ureters in 4 patients had the recurrence of VUR, and in another patient new occurrence was detected postoperatively. Augmentation ileocystoplasty was performed to treat the postoperative decrease of bladder compliance in 4 patients. Among 22 patients who had hydronephrosis preoperatively, 9 (40.9%) showed improvement and none suffered from aggravation of this condition. None of the patients showed a decline of renal function, except for 1 who had a serum creatinine of 2.5 mg/dl preoperatively and developed end-stage renal failure at 7 years postoperatively. CONCLUSIONS: The Cohen procedure has an excellent anti-reflux effect. It is one of the therapeutic options for VUR in patients with good bladder compliance.     

Urinary urgency and reflex incontinence

Urge and reflex incontinence are caused by detrusor dysfunction:urgency may be due to hyperactivity or hypersensitivity of the bladder. Neurogenic hyperactivity of the detrusor is called detrusor hyperreflexia: the neurogenic uninhibited bladder is caused by incomplete, and the so-called reflex bladder by complete, suprasacral lesions. The pathophysiology of symptomatic and idiopathic detrusor hyperactivity and the therapeutic armentarium are described. Bladder drill together with biofeedback and pharmacotherapy with spasmolytic drugs - several potent spasmolytic drugs with different modes of action are available - are the basis of treatment for hyperactivity and hypersensitivity of the detrusor. An alternative is electrostimulation: stimulation of the afferents of the pudendal nerve, via the pelvic floor (anal, vaginal), percutaneously (dorsal nerve of the penis, clitoric nerve) or by the implantation of electrodes results in inhibition of the detrusor. Most (80-90%) patients can be treated successfully by conservative means. Operative measurements comprise bladder denervation and bladder augmentation. The results of bladder denervation by transtrigonal phenolization of the pelvic plexus are highly controversial. In patients with uncontrollable hyperactivity of the detrusor, augmentation of the bladder (e.g. clam ileocystoplasty) is the method of choice, while for those with uncontrollable hypersensitivity of the detrusor, cystectomy followed by bladder substitution should be performed as a last resort. Treatment for urinary incontinence due to detrusor hyperreflexia must be selected bearing in mind that bladder emptying is inadequate, in most cases because of dyssynergia between detrusor and external sphincter. Therapy is basically aimed at transforming hyperreflexia of the detrusor into hyporeflexia, primarily by potent spasmolytic drugs.(ABSTRACT TRUNCATED AT 250 WORDS)     

Use of polydimethylsiloxane for endoscopic treatment of neurogenic urinary incontinence in children

PURPOSE: We report on the injection of polydimethylsiloxane for endoscopic treatment of urinary incontinence in children with neurogenic bladder and determine the optimal criteria for patient selection. MATERIALS AND METHODS: We have treated 17 boys and 16 girls since 1995. The etiology of incontinence was spina bifida in 24 cases. Previous surgery was performed in 18 patients, including bladder neck reconstruction in 15 and bladder augmentation in 9. Mean patient age at injection was 13 years (range 7 to 17). We administered 1, 2 and 3 injections in 21, 11 and 1 patients, respectively. Mean volume at each injection was 3.2 cc. Mean interval between injections was 6 months (range 3 to 15). In all cases injection was done transurethrally. RESULTS: Followup ranged from 6 to 41 months (median 16). A total of 11 patients (33.3%) are dry (continence for greater than 4 hours and no urinary pad use during the day) and 8 (24.2%) are improved (continence for 2 to 3 hours and minimal pad use). Results are poor in 14 cases. Overall previous bladder neck surgery or preoperative detrusor hyperactivity did not influence results. Good results were mainly associated with female gender (47.4% of girls versus 10.5% of boys achieved cure). CONCLUSIONS: Injection of polydimethylsiloxane at the bladder neck resulted in continence in 33% of neurogenic bladder cases. Better results occurred in girls and injection did not compromise other surgical procedures. Polydimethylsiloxane seems more suitable than bovine collagen due to potential problems with biological product use.     

阑尾或肠管可控输出道在神经源性膀胱治疗中的应用

目的：评价阑尾或肠管可控输出道在高反射性神经源性膀胱治疗中的应用价值。方法：采用阑尾输出道（Mitrofanoff法）治疗高反射性神经源性膀胱患者4例,采用回肠腹壁造口（Yang-Monti法）治疗2例。3例采用膀胱自扩大,同时行阑尾输出道2例,回肠腹壁造口1例;3例行回肠膀胱扩大,同时采用阑尾腹壁造口2例,回肠腹壁造口1例。结果：术后随访3～39个月（平均20个月）。1例采用回肠扩大阑尾VZQ造口的患者术后2周造口部皮瓣感染坏死,改行阑尾直接造口;1例阑尾输出道出现造口部位漏尿,缩短导尿间隔为2h,漏尿消失;其他患者控尿良好。5例术后肾功能恢复正常,1例保持稳定。结论：阑尾或回肠可控输出道在高反射性神经源性膀胱治疗中是一种安全可靠的方法。     

Functional results after ileocystoplasty

The functional results after ileocystoplasty were studied in seven patients with interstitial cystitis, irradiated bladder and neurogenic bladder dysfunction. None of the patients had had symptomatic improvement by medical or surgical means. All patients were suffering from urinary frequency and five patients had severe urge incontinence or suprapubic pains. Postoperatively the patients were followed from 8 to 66 months and evaluated by urodynamic examinations and interviews. Urinary frequency was improved in all patients but one with interstitial cystitis who had persisting suprapubic pains. None had residual urine volume greater than 30 ml postoperatively. It is concluded that bladder augmentation by ileocystoplaty is an excellent method of treatment for patients with contracted bladder secondary to interstitial cystitis, irradiated bladder, and detrusor hyperreflexia and sphincter dyssynergia.     

Collagen injection for treatment of urinary incontinence in children

PURPOSE: We assess the success rate of periurethral collagen injection in children with neurogenic bladder dysfunction secondary to myelomeningocele. MATERIALS AND METHODS: From 1992 to 1998, 15 male and 5 female patients with spina bifida (age 13.3 +/- 3.8 years) underwent endoscopic collagen injection for the treatment of urinary incontinence secondary to sphincter deficiency. Mean followup was 4.2 years. Pretreatment urodynamic study showed a stable compliant bladder with an average leak point pressure of 52 cm. H2O (range 23 to 100). Concurrent medical management included anticholinergics in 15 cases, agonists in 3, and clean intermittent catheterization in 16. Five patients had undergone previous ileocystoplasty. RESULTS: Collagen injections were given with the patient under general anesthesia. The number of injections was 1 in 5 cases, 2 in 11, 3 in 3, and 4 in 1. Average collagen volume injected per treatment was 6.6 cc (range 2 to 13). All patients were evaluated on a subjective continence scale of no change (wet), improved or completely dry at the time of assessment. Of the 20 patients, 16 had no change, 3 showed improvement and 1 was dry. Initial improvement in the first 2 months after injection deteriorated thereafter in 16 cases. CONCLUSIONS: The previously reported high success rate of collagen injection is not supported by this study. With long-term followup collagen injection is rarely effective for treating urinary incontinence in children with neurogenic sphincter deficiency.     

Clean intermittent catheterization in the management of spina bifida: a review of 113 cases

One hundred and thirteen cases of spina bifida treated with clean intermittent catheterization (CIC) were reviewed. There were 42 males and 71 females, ranging from 4 months to 50 years. The major reasons for CIC from other voiding methods were vesicoureteral reflux (VUR) (48/113) old, and residual urine (36/113). The most common type of neurogenic bladder was hypoactive detrusor-active sphincter, in 56.6% of patients (64/113). The grade of paralytic disability of lower limb (Sharrard's classification) was low (group IV-VI) in 84 patients and high (group I-III) in 29 patients. Hydroureteronephrosis and VUR improved 52.1% (37/71) and 57.1% (36/63), urinary tract infection and urinary incontinence improved 70.9% (39/55) and 81.7% (72/87). Major complications were pyelonephritis (12 cases) and urethral pain (5 cases). We discussed the choice of voiding method in the management of spina bifida.     

Quo vadis? Ureteric reimplantation or ignoring reflux during augmentation cystoplasty

OBJECTIVE: To decide whether antireflux surgery should be used in the presence of vesico-ureteric reflux (VUR) in children, in whom an augmentation procedure is needed, because secondary VUR in children with a neurogenic bladder, infravesical obstruction and primary VUR in the exstrophy-epispadias complex is expected to resolve after augmentation, which decreases the intravesical pressure and increases capacity. PATIENTS AND METHODS: Between 1987 and 2001, the bladder was augmented in 38 children, using no antireflux surgery in group 1 (15 patients) and antireflux surgery in group 2 (23 patients). RESULTS: VUR was detected in all patients on cysto-urethrography before surgery; reflux resolved after augmentation cystoplasty in 97% and 93% of refluxing units in groups 1 and 2, respectively. The increase in the expected bladder capacity was from 35% to 86% in group 1 and from 38% to 90% in group 2. No patient had any deterioration in renal function. CONCLUSIONS: We recommend using only augmentation in patients with low- or high-grade VUR and a neurogenic bladder, infravesical obstruction and exstrophy-epispadias. Combining antireflux surgery with cystoplasty has no significant effect on either the resolution of VUR or renal function.     

THE YOUNG-DEES-LEADBETTER BLADDER NECK REPAIR FOR NEUROGENIC INCONTINENCE

PURPOSE: We review our experience with the Young-Dees-Leadbetter bladder neck repair among patients with neurogenic incontinence. MATERIALS AND METHODS: Between 1978 and 1997, 25 girls and 13 boys with a mean age of 10.5 years (range 5 to 25) underwent a standard Young-Dees-Leadbetter bladder neck repair for neurogenic incontinence. Of the 38 patients 26 had undergone prior urological surgery, including bladder neck surgery in 6 and bladder augmentation in 4. A primary Young-Dees-Leadbetter bladder neck repair was performed in 24 patients, a secondary Young-Dees-Leadbetter procedure in 6 and a primary Young-Dees-Leadbetter procedure with periurethral silicone sheath placement in 8. RESULTS: Of the 38 patients 30 (79%) are dry, 7 (18%) are partially dry and 1 remains incontinent. Total or partial dryness was achieved after the initial repair in 26 cases (68%), while 8 required an additional procedure and 3 required more than 2 procedures to achieve continence. All patients who underwent silicone sheath placement were initially dry but incontinence developed subsequently in 5 due to sheath erosion. Of the 38 patients 35 (92%) ultimately required bladder augmentation. CONCLUSIONS: The management of neurogenic incontinence remains difficult. Success with the Young-Dees-Leadbetter procedure in our experience nearly always requires augmentation cystoplasty. The majority of patients will achieve continence after the initial procedure, and persistent incontinence can frequently be cured with further bladder neck surgery.     

An artificial somatic-autonomic reflex pathway procedure for bladder control in children with spina bifida

PURPOSE: Neurogenic bladder is a major problem for children with spina bifida. Despite rigorous pharmacological and surgical treatment, incontinence, urinary tract infections and upper tract deterioration remain problematic. We have previously demonstrated the ability to establish surgically a skin-central nervous system-bladder reflex pathway in patients with spinal cord injury with restoration of bladder storage and emptying. We report our experience with this procedure in 20 children with spina bifida. MATERIALS AND METHODS: All children with spina bifida and neurogenic bladder underwent limited laminectomy and a lumbar ventral root (VR) to S3 VR microanastomosis. The L5 dorsal root was left intact as the afferent branch of the somatic-autonomic reflex pathway after axonal regeneration. All patients underwent urodynamic evaluation before and after surgery. RESULTS: Preoperative urodynamic studies revealed 2 types of bladder dysfunction- areflexic bladder (14 patients) and hyperreflexic bladder with detrusor external sphincter dyssynergia (6). All children were incontinent. Of the 20 patients 17 gained satisfactory bladder control and continence within 8 to 12 months after VR microanastomosis. Of the 14 patients with areflexic bladder 12 (86%) showed improvement. In these cases bladder capacity increased from 117.28 to 208.71 ml, and mean maximum detrusor pressure increased from 18.35 to 32.57 cm H2O. Five of the 6 patients with hyperreflexic bladder demonstrated improvement, with resolution of incontinence. Urodynamic studies in these cases revealed a change from detrusor hyperreflexia with detrusor external sphincter dyssynergia and high detrusor pressure to nearly normal storage and synergic voiding. In these cases mean bladder capacity increased from 94.33 to 177.83 ml, and post-void residual urine decreased from 70.17 to 23.67 ml. Overall, 3 patients failed to exhibit any improvement. CONCLUSIONS: The artificial somatic-autonomic reflex arc procedure is an effective and safe treatment to restore bladder continence and reverse bladder dysfunction for patients with spina bifida.     

The artificial urinary sphincter AMS 800 in the treatment of complex female urinary incontinence: indications, results, complications and risk factors

Summary Indications, results and complications of 144 women who have undergone implantation of the current model AMS 800 since 1983 and remained in continuous follow-up in our department are presented. Included are 70 patients suffering from stress urinary incontinence (SUI) type III after 208 previously unsuccessful incontinence procedures, 54 patients with incontinence due to neurogenic bladder dysfunction (NBD) and 20 patients with congenital or acquired internal sphincter weakness of other causes. In the NBD group, apart from sphincter implantation a total of 113 additional operations were necessary due to complex malfunctions of the urinary tract: augmentation ileocystoplasty in 51 patients, ureterocystoneostomy in 23 patients and 43 operations at the bladder neck. One hundred and twenty-six patients (86 %) achieved total continence and 5 patients (3 %) were significantly improved. In 9 females (6 %) incontinence persisted, and 4 patients ultimately underwent urinary diversion into a Kock pouch. With the implanted artificial sphincter 116 patients (81 %) are able to empty their bladder spontaneously, without residual urine and without the necessity of intermittent self catheterisation. Under the aforementioned conditions implantation of the artificial urinary sphincter AMS 800 is the most effective therapy for complex female incontinence.      

Puboprostatic sling repair for treatment of urethral incompetence in adult neurogenic incontinence

PURPOSE: An incompetent urethral sphincter can be a significant factor contributing to urinary incontinence in patients with neurogenic bladders. We review our experience with 12 men who underwent a puboprostatic sling. MATERIALS AND METHODS: The study included 12 men (mean age 37.1 years) with neurogenic bladder due to spinal cord injury in 9 and spina bifida in 3. All patients were diagnosed with urethral incompetence based on fluorourodynamic evaluation. Medical therapy failed in all 12 patients and all complained of urine leakage with activity. All patients underwent placement of an autologous fascial sling distal to the prostatic urethra via an abdominal approach. Ten patients also underwent simultaneous bladder augmentation to correct high intravesical pressures. RESULTS: Followup ranged from 1 to 39 months (average 14.25). All patients manage the bladder with intermittent catheterization. Of the patients 8 are completely dry between catheterizations and 2 had significant improvement with only minimal leakage (1 pad per day), with an overall success rate of 83%. One patient improved initially but subsequently underwent placement of an artificial urinary sphincter for residual stress incontinence. In 1 patient several external sphincterotomies failed despite adequate sling placement. There were no complications related to the placement of the sling and all patients are able to perform intermittent catheterization without difficulty. CONCLUSIONS: In select male patients the puboprostatic sling can be an effective and safe method to treat urethral incompetence secondary to neurogenic voiding dysfunction.     

Post-augmentation bladder perforation during urodynamic investigation

AIMS: To report for the first time bladder rupture during filling cystometry many years after bladder augmentation. METHODS: A 17-year-old girl with T10 meningomyelocele had received an ileocystoplasty, continent catheterizable stoma, and bladder neck sling for neurogenic bladder dysfunction and intractable incontinence 8 years previously. She was continent with clean intermittent self-catheterization four times per day. Yearly urodynamics showed a bladder capacity of up to 700 ml with good compliance and low bladder pressures. In March 2006, filling cystometry was performed. RESULTS: Bladder pressure was normal until 400 ml, after which it increased due to lower compliance. At 620 ml filling, the detrusor pressure was 52 cm H2O, and the patient complained suddenly of abdominal discomfort and bilateral shoulder pain, and the infusion was stopped. A catheter was placed and cystography showed intraperitoneal leakage along the left lateral bladder aspect and at the Mitrofanoff insertion site on the bladder dome. The perforations were closed via a midline incision and a ventriculoperitoneal shunt had to be exteriorized. There were no post-operative complications and a control cystogram revealed no leakage. CONCLUSIONS: Augmentation ileocystoplasty has been used extensively in order to increase bladder capacity and decrease intravesical pressure. Although spontaneous or traumatic perforation of the augmented bladder has been described previously, it was never reported in correlation with urodynamic investigation. Extreme caution is warranted in the face of decreased compliance during filling cystometry in these patients, even though urodynamics showed good bladder compliance and low bladder pressures many years after ileocystoplasty.     

Long-term outcomes of augmentation ileocystoplasty in patients with spinal cord injury: a minimum of 10 years of follow-up

Study Type – Therapy (case series) Level of Evidence 4 What's known on the subject? and What does the study add? Suprasacral spinal cord injuries can result in intractable detrusor overactivity adversely effecting patients’ quality of life. It can lead to high pressure bladder resulting in urinary incontinence and deterioration of upper tract function. Augmentation cystoplasty is an accepted procedure in treating refractory neurogenic detrusor overactivity. Several publications have reported on the short‐ to intermediate‐term outcomes with augmentation cystoplasty in patients with spinal cord injury. However, it is not known how these outcomes alter over a longer period. This study has a follow‐up of at least 10 years. It evaluates the durability of this procedure over the longer term. It also assesses the patients reported outcome over this period. This data can help counsel patients better when considering augmentation cystoplasty as a treatment option for the management of refractory neurogenic detrusor overactivity secondary to spinal cord injury.

OBJECTIVE

• ? To report the long‐term outcomes of augmentation ileocystoplasty (AIC) in patients with spinal cord injury (SCI), with a minimum follow‐up period of 10 years.

PATIENTS AND METHODS

• ? We retrospectively analysed all operations performed by a single surgeon at a specialist spinal unit.
• ? Outcomes were measured by comparing preoperative and follow‐up videocystometrograms (VCMGs).
• ? Complications were identified from case notes and the surgery database.
• ? Subjective assessment was through a previously validated questionnaire.

RESULTS

• ? The mean (range) follow‐up was 14.7 (10.5–20.3) years. There were 19 patients (12 males) with a mean (range) age at time of surgery of 28.9 (12–52) years. The mean (range) period from injury to surgery was 4.5 (0.3–22) years. All had suprasacral injuries.
• ? The VCMGs showed a significant improvement in bladder capacity and a decrease in intravesical pressures (P < 0.001).
• ? Long‐term complications included bladder stones (n= 4); urosepsis (n= 2); vesico‐ureteric reflux ([VUR]n= 2), VUR requiring ureteric re‐implantation (n= 1); neurogenic detrusor overactivity ([NDO]n= 1); and laparatomy for bowel obstruction (n= 1). Surveillance cystoscopies did not detect any bladder neoplasms.
• ? The response rate for the questionnaire survey was 14/17; 13/14 patients were satisfied with the operation such that they would consider it again or recommend it to a friend. No patient reported any significant changes in either bowel habit or sexual function.

CONCLUSIONS

• ? We found that AIC has excellent long‐term outcomes in the definitive management of refractory NDO in patients with SCI.
• ? The complications of AIC appear to be more than counterbalanced by a high level of patient satisfaction with the procedure and by the achievement of the primary aim of ensuring continence and upper tract safety in these patients.

     

Bladder augmentation in three patients with contracted bladder caused by neurogenic bladder

Three patients with contracted bladder caused by neurogenic bladder underwent ileocystoplasty. The primary diagnosis was meningomyelocele for all of them. The operative procedure adopted was Goodwin's Cup-patch method. All cases have obtained increased bladder capacity with improvement of bladder compliance and have been free from urinary incontinence. They were followed up by using clean intermittent self catheterization. Ileocystoplasty combined with clean intermittent self catheterization offers a successful method in patients with contracted bladder caused by neurogenic bladder.
