Abstract
The basic principles of continent cutaneous urinary diversion focus on the creation of a high-capacity and low- can easily and completely be emptied by clean intermittent self catheterization at socially acceptable intervals, while reliably preserving renal function and providing full continence day and night by its specific outlet . The ideal pouch channel needs to be easily catheterizable and have long-term continence and a low complication rate. While neobladder formation is continuously gaining popularity among surgeons and patients, continent coetaneous diversion is still a valid option when orthotopic reconstruction is not feasible. It may be offered to patients who require radical surgery, including urethrectomy. Cutaneous urinary diversion with anumbilical stoma reliably provides complete continence in the vast majority of patients with minimal impairment of the body image. However, careful patient selection with respect to patient intellectual capacity, motivation, compliance, and manual dexterity to perform a self catheterization is required to ensure success of the continent cutaneous reservoir in the long run. A concealed umbilical stoma is the site of preference. In addition to cosmetic results, there are several additional advantages, such as the short distance between the rectus sheath and the umbilical funnel. Moreover, it provides easy access for catheterization of patients in wheelchairs . It must also be noted that stricture prevention, better function, avoiding exposed mucosa, and cosmesis are important considerations when constructing continent abdominal stomas. In this study, an S-shaped pouch was used. This pouch has isoperistaltic afferent limb, to which both ureters are in simple end-to-mucosal edge of the split afferent ileal limb with complete seromuscular wrapping of ileal flap around lower end of each ureter . This acts as an antireflux technique, creating a good volume pouch with an active antireflux mechanism . Conclusions: The functional results with this catheterizable umbilical low pressure intestinal pouch incorporating our new anti-reflux technique were satisfactory with better cosmesis, but more cases and long term follow up is mandatory for that sound conclusion and functional outcome.
