title: The tapered and reimplanted small bowel as a variation of the Mitrofanoff procedure: preliminary results.
abstract: Ten patients with a urethra that could not be catheterized and with absent appendixes underwent neobladder construction using an ileal segment fashioned to serve as the anti-incontinence mechanism. The latter was tapered and reimplanted following the guidelines of the Mitrofanoff procedure. Urinary reservoirs were constructed from detubularized segments of right colon, sigmoid colon and composite gastro-ileal combinations. Followup ranged from 9 to 21 months (mean 14.5). All patients presently catheterize the reservoir satisfactorily and are free of urinary leakage. Three patients (30%) experienced initial catheterization difficulties: 2 required endoscopic procedures and insertion of a stent, and 1 with stomal stenosis was successfully treated with a Y-V stoma plasty. One patient (10%) required a repeat ileal segment reimplantation due to urinary incontinence. The higher reoperation rate and the increased surgical complexity of this procedure compared with reconstructions using the ileocecal valve as part of the anti-incontinence mechanism make this operation a less attractive alternative in the creation of a continent urinary reservoir. However, with comprehension of the need for careful and detailed surgical technique in its creation, the tapered and reimplanted ileal segment is a successful choice as an alternative for the creation of an abdominal wall stoma when the appendix is unavailable.
