PURPOSE: We report our continuing experience with seromuscular colocystoplasty lined with urothelium. This procedure is designed to preserve the urothelium and potentially decrease the incidence of complications associated with standard bladder augmentation. MATERIALS AND METHODS: We retrospectively reviewed the charts of 32 patients who underwent seromuscular colocystoplasty lined with urothelium between April 1994 and July 1999. Data were collected on patient demographics, surgical indications, previous and adjunctive surgical procedures, preoperative and postoperative urinary continence, upper urinary tract changes, urodynamic parameters, surgical complications and histological findings. RESULTS: Mean patient age at surgery plus or minus standard deviation was 11.1 +/- 4.8 years. Mean followup was 1.6 +/- 1 years. A mean of 1.5 +/- 0.9 years postoperatively urodynamic studies available in 28 cases showed that total and safe bladder capacity increased by 1.8 and 2.4-fold, respectively. Continence was achieved in 71% of patients after the initial procedure, increasing to 81% after secondary procedures. Hourglass deformity developed in 7 cases (22%), augmentation failed in 4 (12.5%) and there were bladder calculi in 2 (6%). New onset or increased hydronephrosis and reflux were present in 6 of 62 (10%) and 9 of 60 (15%) evaluated renal units, respectively. Of the 7 interpretable biopsies 5 revealed various degrees of repeat colonic mucosal growth. There was no bladder perforation or metabolic abnormalities, and mucous production was not clinically significant. CONCLUSIONS: Seromuscular colocystoplasty lined with urothelium is a viable alternative to standard bladder augmentation. The 2 procedures have a similar overall complication rate. Comparatively there appears to be a low incidence of bladder calculi, mucous production has not been clinically significant, metabolic disturbances have not developed and perforation has not occurred during short-term followup. We are enthusiastic about this technique and continue to apply it in select patients. 相似文献

Gastrocystoplasty: is there a consensus? 总被引:5,自引:0,他引:5
The problems encountered with ileal and colocystoplasty have led to the use of the stomach for bladder augmentation, termed
gastrocystoplasty. The advantages of gastrocystoplasty over intestinal segment augmentation include reduced chloride reabsorption,
decreased mucus production, decreased urinary infection in the presence of acid urine, extremely low incidence of stones,
and avoidance of complications from short bowel syndrome. The gastric patch provides comparable improvements in bladder volume,
pressure, and continence. The thick muscular wall of the stomach facilitates ureteric reimplantation as compared with the
small intestine, but the rate of stenosis and reflux may not be superior. The disadvantages of the gastric patch include complications
of severe systemic alkalosis, which is usually manifest in dehydrated, renal compromised patients, and the hematuria-dysuria
syndrome (HDS), which is more prevalent in patients with renal insufficiency, normal pelvic sensation, and urinary incontinence.
The postoperative complication rate of gastrocystoplasty is comparable with that of other augmentation procedures and similarly
warrants proper selection and close follow-up of patients. In this report we review the literature and present the results,
including a discussion of the technique and the pathophysiology of its complications. 相似文献

OBJECTIVE: Traditional augmentation cystoplasty using gastrointestinal segments is known to be associated with metabolic abnormalities and alterations in the bladder causing potential carcinogenesis. In this respect alternative techniques have been searched preferably lined by urothelium. We performed ureterocystoplasty in 7 patients with a diagnosis of neurogenic bladder and investigated the clinical and functional aspects. PATIENTS AND METHODS: Between 1995 and 1999, ureterocystoplasty was performed using both ureters in 4 male and 3 female children with bilaterally functional kidneys. Patients' ages varied between 1 and 7 (mean 4.7) years. Before the operation all the children were incontinent, had a small-capacity noncompliant bladder, and high-grade (IV-V, International Classification System) reflux on voiding cystouretrography (VCU). Technetium-99m DTPA renal scintigraphy was also performed in all children to evaluate renal function before and after the operation. RESULTS: Before the operation the mean end-filling intravesical pressure was 45.6 (35-60) cm H(2)O which decreased to 18.9 cm H(2)O 3 months postoperatively. The mean bladder capacity 3 months after ureterocystoplasty was found to be 279.3 (250-330) ml. All the children were continent and VCU showed the absence of reflux. There was mild to moderate improvement in renal function after surgery in both kidneys on technetium-99m DTPA renal scintigraphy. Three (43%) patients could void spontaneously with abdominal straining, whereas 4 (57%) children could empty their bladders by clean intermittent catheterization. A double-J stent was inserted in 1 (14%) patient because of a rise in serum creatinine after the removal of the ureteral catheter. Patients were followed for a mean period of 30 (8-50) months and all the children remained continent. The bladder capacity and end-filling pressure measurements were also stable. CONCLUSION: Ureterocystoplasty was found to be an effective method for bladder augmentation in bilaterally functional kidneys with an acceptable complication rate 相似文献

Background
Enterocystoplasty is associated with serious complications resulting from the chronic interaction between intestinal epithelium and urine. Composite cystoplasty is proposed as a means of overcoming these complications by substituting intestinal epithelium with tissue-engineered autologous urothelium.Objective
To develop a robust surgical procedure for composite cystoplasty and to determine if outcome is improved by transplantation of a differentiated urothelium.Design, setting, and participants
Bladder augmentation with in vitro–generated autologous tissues was performed in 11 female Large-White hybrid pigs in a well-equipped biomedical centre with operating facilities. Participants were a team comprising scientists, urologists, a veterinary surgeon, and a histopathologist.Measurements
Urothelium harvested by open biopsy was expanded in culture and used to develop sheets of nondifferentiated or differentiated urothelium. The sheets were transplanted onto a vascularised, de-epithelialised, seromuscular colonic segment at the time of bladder augmentation. After removal of catheters and balloon at two weeks, voiding behaviour was monitored and animals were sacrificed at 3 months for immunohistology.Results and limitations
Eleven pigs underwent augmentation, but four were lost to complications. Voiding behaviour was normal in the remainder. At autopsy, reconstructed bladders were healthy, lined by confluent urothelium, and showed no fibrosis, mucus, calculi, or colonic regrowth. Urothelial morphology was transitional with variable columnar attributes consistent between native and augmented segments. Bladders reconstructed with differentiated cell sheets had fewer lymphocytes infiltrating the lamina propria, indicating more effective urinary barrier function.Conclusions
The study endorses the potential for composite cystoplasty by (1) successfully developing reliable techniques for transplanting urothelium onto a prepared, vascularised, smooth muscle segment and (2) creating a functional urothelium-lined augmentation to overcome the complications of conventional enterocystoplasty. 相似文献15.

IntroductionBladder augmentation can be performed by detubularization of the small or large intestine. A large capacity bladder is necessary to avoid frequent urination; thus, the ileal sac must be able to store the maximum volume of urine with relatively low pressure and the shortest length of the intestine. The acceptable pressure capacity should always be under ureteric pressure to avoid back pressure and kidney damage. Large capacity at low pressure is referred to as good compliance. Desirable preparations for augmentation, which is the use of the shortest length of the intestine, reduce the chance of diarrhea and vitamin deficiency and retain the intestines which may be required for augmentation.AimClinical and urodynamic evaluation of the recent postoperative condition of the patient who underwent ileocystoplasty, confirmed by the theory of detubularization (spherical) configuration.Case presentationPatient with complaints of frequent urination and small amount of urine. Ultrasound examination showed low volume bladder capacity and bilateral hydronephrosis and hydroureter. From cystography and VCUG examination, low capacity bladder, grade 1 VUR on the right side, grade 4 VUR on the left side accompanied by bilateral hydronephrosis and hydroureter. The patient has a history of right nephrectomy in 2014 for pyonephrosis due to kidney stones. The patient was then subjected to bladder augmentation using a segment of the ileum (ileocystoplasty) in 2015. In the postoperative evaluation, clinical symptoms, radiological and uroflowmetric examinations were evaluated.ConclusionThe detubularization form offers greater volume and lower pressure in the reservoir to augment the bladder. 相似文献

Purpose
We describe the use of a serous lined extramural tunnel for ureteral reimplantation during augmentation of a neurogenic bladder to prevent reflux.Materials and Methods
A 46-year-old male C6 spinal cord injury patient presented with a high pressure bladder, detrusor-sphincter dyssynergia and bilateral grade II/III vesicoureteral reflux. Despite maximal anticholinergic therapy and intermittent catheterization, detrussor pressures were between 80 and 100 cm. water at volumes of 100 to 150 cc with consistent leakage between catheterizations. Preoperative ultrasound and voiding cystourethrogram demonstrated moderate bilateral hydronephrosis and a heavily trabeculated bladder. Augmentation cystoplasty with the formation of 3 cm. extramural ureteral tunnels as described by Ghoneim was performed. The serosa of the adjacent limbs of the ileal segment were opposed to form the back wall of a serosal lined tunnel.Results
At 3 weeks postoperatively a cystogram demonstrated no extravasation or reflux. At 8 weeks an excretory urogram showed prompt function and excretion bilaterally with marked improvement of preoperative hydronephrosis.Conclusions
Subserosal ureteral tunnels can be used as an alternative antireflux technique during augmentation cystoplasty when ureteral reimplantation is required. Two advantages of this technique include the elimination of staples and avoidance of ischemic problems associated with an afferent intussuscepted nipple valve. 相似文献19.

Purpose:
Bladder autoaugmentation is a procedure that includes detrusoromyotomy or detrusorectomy with an aim to release intact urothelium, which then prolapses and increases bladder capacity and compliance. Covering of the prolapsed urothelium usually is done by using deepithelialized pedicled colonic or gastric patch. The authors present their first experiences with detrusorectomy using rectus muscle for hitch and backing.Methods:
Between August 1999 and February 2002, autoaugmentation was performed in 19 patients (12 girls and 7 boys) aged 4 to 12 years (median, 8). All patients had a neurogenic bladder with small capacity and poor compliance. Detrusorectomy usually involves the whole upper half of the bladder to achieve regular shape of the huge prolapsed urothelium. Both rectus muscles are dissected from their anterior and posterior sheaths. Urothelium is sutured to the muscle at several points to prevent its retraction and shrinkage. This way, bladder is fixed and hanged on rectus muscles.Results:
Follow-up was 6 to 35 months (median, 21). The new bladder capacity was increased in all patients and ranged from 190 to 411 ml (median, 313). All patients had clinical improvement and better compliance.Conclusions:
Detrusorectomy with rectus muscle hitch and backing is a safe and simple procedure. However, long-term results are needed to define value of this procedure. 相似文献20.
