PURPOSE: To evaluate the safety and efficacy of retrograde placement of single-J stent guided by a flexible cystoscope for management of ureteroenteral anastomotic stricture in patients after radical cystectomy and Bricker urinary diversion.
PATIENTS AND METHODS: Between January 2008 and June 2012, 11 patients with ureteroenteral anastomotic stricture after open radical cystectomy and Bricker urinary diversion were enrolled in this study. All patients were treated with retrograde placement of single-J stent guided by a flexible cystoscope. A 7F single-J stent was placed for 6 weeks.
RESULTS: Of the 11 patients, seven strictures occurred on the left side, two on the right side, and two on both sides. The retrograde procedure was successfully performed in 10 cases, and the remaining 1 was successful on the right side but failed on the left side. Upper urinary tract infection was well controlled in all three patients with fever. After a follow-up of 12 to 66 months, eight patients had long-term symptom relief, one patient had open surgery to remove the stricture and re-implant the ureter, and one patient died because of tumor recurrence. The only failed case was that of a left side percutaneous nephrostomy, but the patient was lost to follow-up.
CONCLUSIONS: Retrograde placement of a single-J ureteral stent guided by a flexible cystoscope is safe and effective for ureteroenteral anastomotic stricture in patients with Bricker urinary diversion, and it brings fewer complications. The procedure is minimally invasive and could avoid immediate surgery for most patients.
