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.     

Left-colon antegrade continence enema (LACE) procedure for fecal incontinence

Purpose: Antegrade continence enemas (ACE) are an efficacious therapeutic option for patients with fecal incontinence. The authors review their institution’s experience with a variation of the Monti-Malone ACE procedure using the left colon as a source of an intestinal conduit and enema reservoir.Methods: From 2000 to 2002, 18 patients with fecal incontinence or intractable constipation underwent left-colon ACE (LACE) procedure. Concomitant Mitrofanoff appendicovesicostomy was performed in 15 patients and bladder augmentation in 9. The majority of patients had neural tube defects. A segment of left colon was tubularized, tunneled into the muscular wall of the distal colon, and exteriorized through the left upper quadrant or midabdomen. Stomal catherization and enema installation were started one month postoperatively.Results: Fifteen patients (83%) achieved fecal continence, 2 remain incontinent of stool, and 1 experienced stomal closure (mean follow-up was 24 ± 9 months). Two patients had stomal stenosis that required revision. The mean enema volume in patient’s achieving continence was 360 ± 216 mL, and the mean transit time was 18 ± 12 minutes.Conclusions: LACE is an efficacious procedure for fecal incontinence that can be performed safely at the time of major urologic reconstruction. Administration of enemas into the left colon has several physiologic advantages that result in predictable bowel evacuation.     

Pediatric urinary incontinence: evaluation of bladder wall wraparound sling procedure

PURPOSE: In 1996 a surgical procedure for sphincter deficiency was reported in patients with neurogenic urinary incontinence. To our knowledge we report the first series that assesses this procedure since it was initially described. MATERIALS AND METHODS: Seven female and 7 male patients with spinal dysraphism and neurogenic intrinsic sphincter deficiency underwent surgery between 1997 and 2005. All patients had an associated poorly compliant or small capacity bladder. Patient age ranged from 8 to 22 years (mean 14) and all patients presented with persistent urinary incontinence despite intermittent catheterization and pharmacotherapy. Evaluation was based on clinical examination, as well as preoperative and postoperative urodynamic assessments. The surgical procedure involved wrapping a pedicle strip of anterior bladder wall around the bladder neck and fixing it on the pubic symphysis. Bladder augmentation cystoplasty was also routinely performed during the same procedure. RESULTS: Of 14 patients 13 were completely dry and 1 had stress incontinence. Followup was 2 to 8 years (mean 5). Postoperative urodynamic evaluation showed a maximum urethral pressure increase of 40%. We also observed an increase in bladder capacity of 105% and improved bladder compliance (7 ml/cm H(2)O preoperatively vs 35 ml/cm H(2)O postoperatively). CONCLUSIONS: The bladder wall wraparound sling procedure provides excellent results for continence in association with bladder augmentation.     

Modified apical dissection for early continence after radical prostatectomy

A prospective evaluation of urinary continence in 83 consecutive patients undergoing radical prostatectomy using a modified apical urethral dissection is described. Using this technique, complete continence has been achieved in 88%, with stress incontinence in 11% and total incontinence in 1%. Continence was achieved in less than 1 week to a maximum of 16 weeks, with 17% dry during the first week, 53% dry by 6 weeks, and 81% by 3 months. Median time to continence was 5 weeks. Median age of the continent patients was significantly lower than that of incontinent patients. Neither the number of neurovascular bundles resected, the need to reconstruct the vesical neck, nor the number of anastomotic sutures used affected the rate of continence. The described technique, which incorporates the fascia posterior to the urethra into the vesicourethral anastomosis, results in earlier continence after radical prostatectomy, and thereby lessens the morbidity of this procedure. © 1993 Wiley-Liss, Inc.     

An adjustable continence therapy device for treating incontinence after prostatectomy: a minimum 2-year follow-up

OBJECTIVE

To evaluate the efficacy and safety of the ProACT^TM (Uromedica, Inc., MN, USA) balloon device, an alternative for the surgical management of incontinence after prostatectomy.

PATIENTS AND METHODS

The initial patients who received this device at our institution were evaluated, using urodynamics at baseline and at 6 months. Perioperative variables were recorded and pad usage, volume adjustments, an estimate of Incontinence Quality of Life (I‐QoL) and adverse events were recorded at baseline, and 1, 3, 6, 12 and 24 months after surgery.

RESULTS

In all, 37 patients were treated on this protocol between November 2001 and March 2005. Of these, 30 had had radical prostatectomy and seven holmium laser enucleation of the prostate. The mean (range) pad usage decreased from 2.81 (1–12) at baseline to 0.7 (0–4) pads at 24 months, and the I‐QOL increased from 49.7 (4.5–77) to 81.3 (13.6–100) over the same period. At 24 months, 62% of 34 men were pad‐free and 81% required one pad or less. Bilateral explantation was required in three patients (11%) for infection (one) and balloon migration (two). All other adverse events were mild and transient.

CONCLUSIONS

The ProACT balloon device is an acceptable therapy for the surgical management of incontinence after prostatectomy.     

Urinary continence and pathological outcome after bladder neck preservation during radical retropubic prostatectomy: a randomized prospective trial

PURPOSE: Bladder neck preservation during radical prostatectomy has been advocated for improving urinary continence. We compared bladder neck preservation and resection in a randomized trial, looking at continence rates and surgical cancer control. MATERIALS AND METHODS: Patients with stage T1c-T2c prostate cancer underwent radical retropubic prostatectomy with maximal preservation of the external urinary sphincter. Bladder neck preservation or resection was chosen by chance during surgery. Urinary continence (1 or no protective pad daily) was assessed by interview 2 days after catheter removal, and 2 and 6 months after surgery. The surgeon, pathologist and interviewer were the same throughout. Neither patient nor interviewer knew which procedure was done. Planned enrollment was 120. RESULTS: Enrollment was stopped after 70 patients because surgical margins were positive only at the bladder neck in 10% of the preservation group but in none of the resection group (p = 0.08). Each group was assigned 35 patients but the bladder neck could not be preserved in 4 and 1 died, leaving 31 in the preservation group and 38 in the resection group. There were no statistically significant differences between groups in early or late urinary continence rates. Two days after catheter removal, and 2 and 6 months after surgery the respective rates were 79%, 87% and 95% with resection, and 67%, 87% and 97% with preservation. CONCLUSIONS: In our opinion bladder neck preservation during radical retropubic prostatectomy does not improve urinary continence and might compromise cancer control. The external sphincter appears more important for continence after radical prostatectomy.     

The Malone antegrade continence enema procedure: the Amsterdam experience

Background

The Malone antegrade continence enema (MACE) procedure has been previously described as a safe and effective option for the treatment of children with chronic defecation disorders when maximal medical therapy and conventional treatment have failed.

Purpose

To evaluate clinical success, complications, and quality of life of children with chronic defecation disorders with a MACE stoma.

Methods

A retrospective analysis of 23 patients who underwent the construction of a MACE stoma was performed. Preoperative and postoperative data were evaluated. A specific questionnaire was used to assess patient satisfaction.

Results

A significant increase was found in defecation frequency (1.0 [range, 0-4] pretreatment vs 5.5 [range, 0-28] posttreatment per week; P < .006) and a significant decrease in fecal incontinence frequency (10 [range, 0-14] pretreatment vs 0 [range, 0-14] posttreatment per week; P < .034). Postoperative complications of the MACE procedure were fecal leakage (43%), wound infection (52%), and stomal stenosis (39%). A total of 86% of the patients were satisfied with the results of the Malone stoma (n = 21).

Conclusions

The MACE procedure is an effective treatment in children with intractable defecation disorders. Postoperative complications are, however, not uncommon. Further refinement of the technique focused to reduce the complication rate is necessary to expand the application of this approach.     

After the honeymoon comes divorce: long-term use of the antegrade continence enema procedure

Background

Having reported that 18% of children discontinue use of the antegrade continence enema (ACE) after 5 years, we aimed to determine long-term use after an ACE procedure.

Methods

A postal/telephone questionnaire was conducted. Subjects were consecutive children undergoing an ACE between 1993 and 1999. Outcome measures were use of ACE, reasons for nonuse, complications, and overall satisfaction.

Results

Of 84 eligible subjects, data were available on 61 (73%) aged 22.4 years (15.5-35.1 years). Underlying diagnoses included spina bifida (n = 27), anorectal malformations (n = 18), constipation (n = 11), Hirschsprung's disease (n = 1), sacral agenesis (n = 2), and trauma/tumor (n = 2). Follow-up was 11.02 years (8.34-14.39 years). Thirty-six (59%) of 61 patients were still using their ACE. Reasons for nonuse were lack of effectiveness (n = 14), complications (n = 5), psychologic issues (n = 2), and poor compliance (n = 2). There was no association between diagnosis and nonuse (χ², P = .63). In those still using ACE, the overall satisfaction score was 4.1 (1-5). Several individuals reported feeling abandoned on becoming adults and losing the support they had in childhood.

Conclusion

There is a late “failure” rate for the ACE procedure. However, satisfaction was high among those still using the ACE. This study further emphasizes the need for robust transitional care arrangements.     

Urodynamic effects of propiverine hydrochloride in children with neurogenic detrusor overactivity: a prospective analysis

OBJECTIVES: To evaluate prospectively the efficacy and tolerability of propiverine for treating neurogenic detrusor overactivity (NDO) in children. PATIENTS AND METHODS: Twenty children (mean age 8.9 years; median 5.6) with NDO due to an upper motor neurone lesion were enrolled (17 had myelomeningocele). In the urodynamic examination, reflex volume (RV), maximum detrusor pressure (MDP), maximum cystometric bladder capacity (MCBC) and bladder compliance (BC) before and after a twice-daily propiverine hydrochloride regimen were determined. The urodynamic follow-up was after 3-6 months. Incontinence was assessed by an incontinence score. RESULTS: The mean (sem) RV increased from 103.8 (21.3) to 174.5 (33.7) mL (P < 0.005), MDP decreased from 52.5 (7.9) to 40.1 (6.2) cmH(2)O (P < 0.05), MCBC increased from 166 (28.8) to 231.9 (34.8) mL (P < 0.005), and BC improved from 11.2 (2.8) to 30.6 (9.7) mL/cmH(2)O (P < 0.01), with propiverine treatment. The incontinence score (scale 0-3) improved from 2.4 (0.2) to 1.6 (0.3) (P < 0.05). Propiverine was well tolerated, although some children were given higher doses than recommended. CONCLUSIONS: Propiverine hydrochloride is effective and well tolerated in the treatment of children with NDO. Because of its dual mode of action, it is well tolerated even in children who need higher doses. Propiverine hydrochloride is a preferable alternative to oxybutynin, the anticholinergic most frequently used in children with NDO to date.     

Intravesical resiniferatoxin for the treatment of women with idiopathic detrusor overactivity and urgency incontinence: A single dose, 4 weeks, double-blind, randomized, placebo controlled trial

AIMS: To assess the hypothesis that resiniferatoxin (RTX) can be useful in women with urgency incontinence and idiopathic detrusor overactivity (IDO), we conducted a prospective, double-blind, randomized, placebo-controlled, parallel trial comparing the effects of RTX and placebo. MATERIALS AND METHODS: Fifty-eight patients were randomly assigned to receive a single intravesical dose of 100 ml of either RTX 50 nM or placebo. Safety and efficacy were evaluated over 4 weeks. The primary efficacy endpoints were voiding symptoms evaluated through the voiding diary. Secondary efficacy endpoint was urodynamic response. Quality of life was measured by the Kings' Health Questionnaire RESULTS: Although improving trends were seen in both groups after the instillations, no statistically significant differences were found between the groups in any of the clinical or urodynamic parameters. RTX instillations were well tolerated with few and self-limited side-effects. CONCLUSION: A single 50 nM intravesical dose of RTX was not better than placebo for the treatment of women with IDO and urgency incontinence.     

Factors predicting continence recovery 1 month after radical prostatectomy: Results of a multicenter survey

Objectives: To assess the factors associated with continence recovery 1 month after radical prostatectomy (RP) and to identify the correlation between these factors. Methods: In total, 2408 men treated with RP for prostate cancer (PCa) were enrolled in the present multicenter prospective study. Clinical (age, body mass index) and urological (catheterization or transurethral resection of the prostate) records, quality of life (QOL) scores determined using various instruments (including the International Index of Erectile Function [IIEF] and University of California Los Angeles, Prostate Cancer Index [UCLA‐PCI]), PCa characteristics (clinical stage [cT], prostate‐specific antigen, biopsy Gleason score), surgical features (surgical approach, nerve and bladder neck sparing, catheterization), and pathologic outcomes (pT, pN+, Gleason score, positive surgical margins) were recorded. Continence status prior to surgery and at 1 month after RP was assessed and classified as followed: (i) full continence; (ii) 0–1 pads/day; or (iii) >1 pad/day. Only patients determined to have full continence prior to surgery were included in the analysis. Data were evaluated using Spearman's correlation analysis and multivariate logistic regression. Results: Data from 1972 patients with full continence preoperatively and complete postoperative data were analyzed. At 1 month after RP, 644 patients (32.7%) were fully continent, 810 (41.1%) were using 0–1 pads/day, and 518 (26.3%) were using >1 pad/day. Univariate analysis indicated that clinical and urological data, QOL, PCa characteristics, surgical features, and pathologic outcomes were determinants for continence recovery. Multivariate analysis indicated that preoperative sexual activity (UCLA‐PCI Sexual Function P = 0.005; IIEF P = 0.040), bladder neck sparing (P = 0.003), catheterization time (P = 0.007), and catheter diameter (P = 0.046) were associated with 1 month continence recovery. Conclusions: Age and nerve sparing are not significant predictors of continence recovery 1 month after RP. Preoperative erectile function can predict post‐prostatectomy incontinence. Bladder neck preservation has a significant effect on early continence recovery after RP.     

A randomized controlled trial of the NEAT expandable tip continence device

Urethral devices are one conservative management option for stress and mixed urinary incontinence, but there is little published data about their use. The aims of this study were to assess the safety and efficacy of a new urethral device (NEAT) and compare it with the Reliance Insert. The ease of use of both devices was then evaluated. Twenty-four women with mixed or stress urinary incontinence, patients at our tertiary care urogynecology unit and who met the inclusion and exclusion criteria, were enrolled in the study. Study subjects were blinded and randomly assigned to a device group. Device efficacy was assessed by pad weighing at 0 and 4 months. Success was defined as a 50% or greater reduction in urine loss using the formula 100[(pad weight without device –pad weight with device)/pad weight with device]. Safety was evaluated using urinalysis and urine cultures. Ease of use assessment scales were also completed. Eleven patients were randomized to the Reliance Insert and 13 to the NEAT device. There were no significant differences between the two groups in age, height, weight, duration of incontinence, pad weight, leakage score, parity or quality of life score. Based on the pad weight success formula, there was no significant difference in device success between the two groups at 4 months. Women who were postmenopausal had a trend towards a higher level of success in reduction of their pad weight. Previous treatment, diagnosis and hormone replacement therapy all had no relationship to device success. Leakage score data showed that subjects had a significant decrease in urine leakage when using either device. There was no statistically significant difference in ease of use between the two devices. Adverse symptoms most commonly noted were awareness of the device (62.5%), urgency (29.2%), and urethral discomfort or pain (20.8%). One urinary tract infection (UTI) was observed. The most common finding on urinalysis was trace hematuria (15.8%). Our conclusions are that the NEAT device appears to be at least as effective and safe as the Reliance Insert. Both devices are effective at decreasing urine leakage in patients with stress or mixed urinary incontinence. The risk of UTI is low, but these devices may cause trace hematuria.Abbreviations UTI urinary tract infection Editorial Comment: Devices for treatment of urinary incontinence must be safe and effective. This small study was originally part of a much larger study that could address safety and efficacy. Although the number of patients presented in this report is small, the device may be of interest for readers of this journal.     

Orthotopic bladder substitution in men revisited: identification of continence predictors

PURPOSE: We determined the impact of the functional characteristics of the neobladder and urethral sphincter on continence results, and determined the most significant predictors of continence. MATERIALS AND METHODS: A total of 88 male patients 29 to 70 years old underwent orthotopic bladder substitution with tubularized ileocecal segment (40) and detubularized sigmoid (25) or ileum (23). Uroflowmetry, cystometry and urethral pressure profilometry were performed at 13 to 36 months (mean 19) postoperatively. The correlation between urinary continence and 28 urodynamic variables was assessed. Parameters that correlated significantly with continence were entered into a multivariate analysis using a logistic regression model to determine the most significant predictors of continence. RESULTS: Maximum urethral closure pressure was the only parameter that showed a statistically significant correlation with diurnal continence. Nocturnal continence had not only a statistically significant positive correlation with maximum urethral closure pressure, but also statistically significant negative correlations with maximum contraction amplitude, and baseline pressure at mid and maximum capacity. Three of these 4 parameters, including maximum urethral closure pressure, maximum contraction amplitude and baseline pressure at mid capacity, proved to be significant predictors of continence on multivariate analysis. CONCLUSIONS: While daytime continence is determined by maximum urethral closure pressure, during the night it is the net result of 2 forces that have about equal influence but in opposite directions, that is maximum urethral closure pressure vs maximum contraction amplitude plus baseline pressure at mid capacity. Two equations were derived from the logistic regression model to predict the probability of continence after orthotopic bladder substitution, including Z1 (diurnal) = 0.605 + 0.0085 maximum urethral closure pressure and Z2 (nocturnal) = 0.841 + 0.01 [maximum urethral closure pressure - (maximum contraction amplitude + baseline pressure at mid capacity)].
