Étude comparative du drainage urétéral par sonde double J ou sonde urétérale après cystectomie-entéroplastie

Abstract

The aim of the study was to compare ureteroileal anastomosis strictures rates in patients receiving either double J stent or open-ended ureteral stent, after bladder replacement for cancer. Medical charts from 75 patients who underwent cystectomy and Z pouch bladder substitution for bladder cancer, between 2001 and 2005, were retrospectively reviewed. Ureteroileal anastomosis was direct, spatulated end-to-side fashioned in all patients. Double J stents were used in 39 patients (group A) and open-ended ureteral stent were used in 36 patients (group B). Mean hospital stay, early and late complications were also observed. Seventeen anastomotic strictures have been documented during the follow-up: 5.2% in group A versus 18.3% in group B (p=0.012). Mean catheterization period was six weeks in group A and 12 days in group B. No significant differences were found in mean hospital stay, early and late complications. The use of internal double J ureteral stent is now a feasible option and can decrease the rate of anastomotic stricture. The fact that the double J stent is removed after the anastomosis healing period may be a possible explanation.
