Continent cutaneous ileal pouch using the serous lined extramural valves. The Mansoura experience in more than 100 patients.

PURPOSE

We report on the functional results of continent ileal reservoir using serous lined extramural valves for reflux prevention and continent urinary outlet.

MATERIALS AND METHODS

The procedure was performed in 109 patients (68 men, 27 women and 14 children). The operation was indicated as a primary procedure in 93 patients and for conversion in 16. The technique entailed construction of a detubularized W-shaped ileal reservoir in which 2 serous lined troughs were created. Two tapered ileal segments were used, 1 for reflux prevention and the other as a continent outlet. The appendix was used for the construction of the outlet in 44 patients.

RESULTS

Two patients died in the hospital of pulmonary embolism. A total of 22 early complications were observed in 18 patients (16.5%). None of the patients required operative intervention. A total of 93 patients were evaluable with a mean followup of 36.6 +/- 25.4 months. All evaluable patients but 5 were continent day and night. Mean time for catheterization was 4 to 5 hours. There were 14 late complications reported in 11 patients (11.8%), including pouch stones in 5, stomal stenosis in 5, failure to catheterize in 2, parastomal hernia in 1 and adhesive bowel obstruction in 1. Upper urinary tract was stable or improved in 94.8% of the renal units. Clinical acidosis did not develop in any of the patients.

CONCLUSIONS

Serous lined unidirectional valves are reliable. They provide a versatile surgical technique suitable for urinary diversion or conversion procedures. The operation is associated with an acceptable complication rate and is followed by good functional results.
