Sequential dilatation of two balloons and double D-J stents for therapy of ureteroenteral anastomotic stricture in patients following radical cystectomy and Bricker urinary diversion
Abstract
Background: To determine the safety and efficacy of successive retrograde dilatation of two balloons and a double D-J stent for the treatment of ureteroenteral anastomotic strictures in patients who had undergone radical cystectomy and Bricker urinary diversion.
Methodology: A total of 25 patients with ureteroenteral anastomotic stricture following radical cystectomy and Bricker urinary diversion were treated with sequential dilatation of two balloons (F18 and F24), while the remaining other 32 patients were only dilated once. All patients were treated with ureteroscope or flexible ureteroscope-guided retrograde implantation of twin D-J stents (F5).
Results: Sequential dilation required significantly longer hospital stay and surgery time than single dilation. When sequential dilatation was compared to single dilatation, both the length of stay and the time it took to do the operation were clearly longer. After a follow-up of 6 to 24 months, the success rate of sequential dilatation was 61.5%, in comparison to 58.847.1% for single dilatation (P=0.83<0.05). All patients did not appear to have serious complications, such as hemorrhage, intestinal injury, or egression of the stent. No serious complications occurred in all patients, such as hemorrhage, intestinal injury, or egression of the stent.
Conclusion: Sequential retrograde dilatation with two balloons and double D-J stents is thought to be safe and effective for uretero-intestinal anastomotic strictures in patients having with brick ureteral diversions, and it is associated with fewer sequelae. It is worthwhile for clinical purposes.
