Serous lined extramural ileal valve: a new continent urinary outlet
1Urology and Nephrology Center, Mansoura University, Egypt.
Purpose:
We report the functional results following the use of serous lined extramural valve as an antireflux technique and urinary outlet for continent urinary diversion.
Materials And Methods:
The procedure was performed in 18 men and 5 women. The technique entails fashioning 2 serous lined extramural troughs in a detubularized W-shape ileal reservoir. A tapered ileal segment is embedded in 1 trough as an antireflux valve and the ureters are anastomosed to its proximal end. Another tapered ileal segment or the appendix is embedded in the second trough and acts as a continent cutaneous outlet.
Results:
No operative or postoperative mortality was observed. One patient had prolonged ileus which was treated conservatively. All patients were evaluable with a mean followup of 19 months. All patients but 1 were continent day and night. No catheterization difficulties were reported. Evacuation intervals were 4 to 5 hours. Radiographic evaluation demonstrated a continent compliant reservoir, stable and straight outlet, and absence of pouch and ureteral reflux.
Conclusions:
This procedure is technically feasible, surgically versatile, applicable for urinary diversion or conversion and associated with satisfactory outcome.
