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: In 1980 Mitrofanoff described a method to achieve continent urinary diversion by surgically closing the bladder neck and creating a continent catheterizable stoma from the appendix which had been implanted in a nonrefluxing manner into the bladder or from a nonrefluxing distal ureter. The Mitrofanoff principle (MP) serves well as a continence mechanism for either the native bladder or intestinal reservoirs. We review 17 patients, including 10 children, who were treated with the MP and received a continent catheterizable channel. For the MP, appendix was used in 16 patients and ureter in 1. The continuity between the urinary reservoir and urethra was maintained wherever possible. Bladder neck suspension was preferred to bladder neck closure in incontinent females and boys. Complications and their management have been discussed at length. Stable renal functions, ease of catheterization and urinary continence were achieved in 93.8% of the patients.Urologia Internationalis 02/1997; 58(2):108-12. · 1.07 Impact Factor

ABSTRACT: Continent conduits for Mitrofanoff and Malone procedures are widely used for incontinence management. Because the appendix is not always suitable or available, Monti proposed a transversely retubularized short segment of ileum. We present our experience and compare outcomes according to the type of conduit. In a retrospective study from 1988 to 2003 case notes were reviewed specifying conduit characteristics, underlying disease, overall surgical management of incontinence and subsequent complications. Comparison was based on followup, details of complications and treatments. In 32 men and 14 women with a total of 65 conduits (Mitrofanoff in 41 and Malone procedure in 24) the condition was spina bifida in 29, bladder exstrophy in 5 and sacral agenesia in 3. Other cases included various origins. Mean age at operation was 14.2 years (range 1 to 31). Mean followup was 5.3 years (range 1 to 14.7). Appendix was used in 23 cases and a Yang-Monti channel was performed in 18 (ileum in 7 and sigmoid in 11) for urinary diversion. The Malone procedure was performed using appendix in 11 cases and a Yang-Monti tube in 13. At followup 61 conduits (93.8%) were in use and 4 (6.2%) were abandoned. Complications were cutaneous stenosis, kink blockage and stomal leakage. No significant differences were observed between the types and purposes of the conduit. With constant availability and various possibilities of construction the Yang-Monti channel is recommended for continent diversion creation when appendix does not look suitable or is already in use or absent.The Journal of Urology 11/2004; 172(5 Pt 1):1907-10. · 3.70 Impact Factor
