Abstract: | PURPOSE: A modified Le Duc procedure with a short submucosal tunnel was applied for ureteroileal implantation in ileal orthotopic neobladder and bladder augmentation with the ileum. We assessed the rate of stenosis and ureteral reflux at the ureteroileal anastomosis after this procedure. MATERIALS AND METHODS: Two women and 22 men underwent radical cystectomy and creation of a Hautmann ileal neobladder for invasive bladder cancer. Another woman underwent ileal bladder augmentation with bilateral ureteral reimplantation into the ileal segment. Ureteroileal anastomosis was performed using the modified Le Duc technique in 48 renoureteral units. Followup in all patients included retrograde cystography done before discharge home and excretory urography, renal ultrasonography or abdominal computerized tomography every 4 to 6 months. Followup was 11 to 39 months in 23 of the 25 cases. RESULTS: Retrograde cystography before discharge home revealed no urinary reflux in any reimplanted ureter. There was no ureteral stenosis or reflux in 20 male and 3 female patients (44 renoureteral units) who voided successfully without catheterization. A unilateral ureteral stricture at the ureteroileal anastomotic site in 1 man who voided successfully was treated with endoscopic surgery. Bilateral slight upper urinary tract dilatation caused by ureteral reflux was present in another man who did not void successfully. CONCLUSIONS: The modified Le Duc technique is simple and safe for forming an ureteroileal anastomosis in ileal orthotopic neobladder creation. It appears to have a low ureteral stenosis and reflux complication rate in patients who successfully void postoperatively. |
