The role of interventional radiology in the management of intra- and extra-peritoneal leakage in patients who have undergone continent urinary diversion.

<bold>Purpose: </bold>To assess how radiologic intervention altered the hospital course of patients undergoing continent urinary diversion.<bold>Methods: </bold>Thirty-seven consecutive patients with bladder cancer invading the muscular layer were treated with total cystectomy and construction of a continent urinary reservoir. Eleven of 37 patients suffered early and late anastomotic leakage; six had prolonged extraperitoneal leakage at the urethroenteric anastomosis, three had prolonged intraperitoneal pouch leaks, and two had delayed ureteroenteric leaks. Seven of these patients required radiologic intervention.<bold>Results: </bold>Intervention in the form of drainage catheter manipulation (n = 4), percutaneous nephrostomy (n = 4), or ureteral stent placement (n = 2) resulted in cessation of leakage without surgical intervention in all seven patients. Intraperitoneal pouch leaks were more difficult to control than extraperitoneal leakage and required longer drainage intervals.<bold>Conclusion: </bold>Interventional radiologic procedures played a key role in the management of continent urinary diversion complications, obviating the need for repeat surgical intervention in all instances.
