Complications of the catheterizable channel following continent urinary diversion: their nature and timing.
ABSTRACT We reviewed the incidence, nature and timing of complications related to the catheterizable channel following continent urinary diversion.
We retrospectively reviewed the records of 67 patients who underwent continent urinary diversion at British Columbia Children's Hospital from 2000 to 2006. Catheterizable channels included 54 Mitrofanoff appendicovesicostomies and 13 ileovesicostomies. Medical records were reviewed for predetermined complications and their timing, that is early -12 months or less, or late - more than 12 months.
At a median followup of 28 months (range 3 to 62) a total of 17 complications were identified in 14 patients (21%). Superficial cutaneous stenosis developed in 4 of 67 cases (6%) as an early and as a late complication. These cases were initially treated with operative dilation and surgical revision as necessary. Channel stricture, which developed in 4 of 67 patients (6%) as an early and as a late complication, was treated with operative revision in 2 and endoscopic resection in 2. Three patients (5%) had stomal prolapse, which was generally a late occurrence and required operative revision in all. Channel leakage developed in 6 of 67 patients, presenting as an early complication in 50%. Endoscopic injection of bulking agents was attempted in 4 of these patients and it was successful in 2. Overall 82% of complications were successfully managed by endoscopic or superficial procedures.
Complications of the catheterizable channel are a frequent and challenging problem. They appear to occur throughout the life of the channel with most developing within the first 2 years. Further followup is required to assess the performance and durability of continent catheterizable channels in children as patients progress to adulthood.

ABSTRACT: We evaluated the success rate of continent vesicostomy using an ileal segment with seroserosally embedded, tapered ileum for bladder augmentation with continent stoma following bladder neck closure (BNC) for severely damaged bladders or persistent urinary incontinence. A total of 15 patients were treated for persistent urinary incontinence or non-reconstructible bladder outlet between 2003 and 2012. Underlying diagnosis included post-prostatectomy incontinence (n = 5), recurrent bladder neck stenosis (n = 5), neurogenic bladder (n = 3), urethral tumor recurrence following orthotopic neobladder (n = 1) and post-TVT and colposuspension incontinence (n = 1). All patients underwent open BNC, omental interposition and continent vesicoileostomy. The continent outlet was placed in the lower abdomen using a circumferential subcutaneous and skin plasty to avoid retraction. Data collected included age, underlying diagnosis, stoma site, time to complications and need for subsequent surgical revisions. All patients received a standardized questionnaire at the time of data acquisition and were personally interviewed. Median follow-up was 24 months (range: 2-111). Primary BNC was successful in all patients and primary continence rate was 86.7%. Two patients (13.3%) suffered from failure of the continence mechanism, caused by stoma stenosis at skin level and insufficiency of the bladder augmentation and stoma due to local infection. One additional patient developed a mild stomal incontinence without need for further reconstruction. Regardless of the number of revisions, at the last follow-up 93.3% of patients had a functional channel. All complications occurred within the first postoperative year. This technique is an effective last resort treatment for patients with non-reconstructible bladder outlet.Central European journal of urology. 01/2014; 66(4):481-6.

ABSTRACT: Continent catheterizable channels have revolutionized reconstructive surgery to achieve both urinary and fecal continence. The Mitrofanoff and Malone antegrade continent catheterizable channels offer improved quality of life relative to permanent incontinent stomas. A frequently employed surgical option for creating a Mitrofanoff when an existing appendicocecostomy exists involves harvesting a separate piece of intestine. If however the Malone has preceded the creation of a Mitrofanoff, we describe a surgical technique that may avoid the need for a bowel harvest and resultant anastomosis. We report our series of patients utilizing a novel alternative strategy in the select clinical circumstance of an existing appendicocecostomy to expand the armamentarium of the urologic reconstructive surgeon.Journal of Pediatric Surgery 04/2014; 49(4):656-9. · 1.31 Impact Factor
