Urological complications after simultaneous renal and pancreatic transplantation.

Abstract

Objective: To report the urological complications after simultaneous renal and pancreatic transplantation.

Design: Retrospective study.

Setting: Teaching hospital, Italy.

Subjects: 143 consecutive patients having simultaneous renal and pancreatic transplantation by one of three techniques. 33 segmental pancreas with duct occlusion, 77 whole pancreas with bladder diversion, and 33 enteric diversion with systemic (n = 26) or portal venous drainage (n = 7). Urological complications were related to the pancreatic transplant, to the renal transplant, or unrelated to the transplant.

Main outcome measures: Morbidity.

Results: After occlusion of the duct and enteric diversion, there were no urological complications related to the pancreatic transplant. On the other hand, among the 77 patients with pancreatic drainage into the bladder, urological complications were common (56/77; 73%). Complications related to the renal transplant were recorded in 6/33 (18%), 26/77 (34%) and 12/33 (36%), respectively. Complications unrelated to the transplant occurred in 6/77 patients (8%) in the bladder drainage group. Five patients after bladder drainage required cystoenteric conversion.

Conclusions: Enteric diversion is a safe alternative to bladder diversion and results in significantly fewer urological complications.
