Lower pole calicostomy for the management of iatrogenic ureteropelvic junction obstruction.
It is often possible to use endoscopic techniques for the management of iatrogenic upper ureteral or ureteropelvic junction obstruction. However, in some cases with severe stricture disease or significant ischemic injury open surgical reconstruction is necessary. We report our experience with ileal ureter-lower pole calicostomy for the management of these complex urological injuries. During the last 3 years we treated 3 patients with severe ureteral/ureteropelvic junction obstruction secondary to iatrogenic injuries, including ureteral avulsion during ureteroscopic stone extraction, ureteral laceration during dilation for diagnostic ureteropyeloscopy, and ureteral ligation with ureteropelvic junction disruption and large peri-pelvic urinoma. In all cases unsuccessful attempts at endoscopic management necessitated open repair. Lower pole heminephrectomy was performed in all patients to expose the lower pole calix and ileal ureter-lower pole calicostomy was created due to the injury of large segments of the ureter. Satisfactory results were demonstrated on postoperative excretory urography and by a lack of symptoms. Followup averaged 23 months (range 20 to 26) with stable renal function in all patients. We believe that ileal ureter-lower pole calicostomy represents an attractive alternative for the management of severe ischemic, iatrogenic upper ureteral or ureteropelvic junction obstruction when endoscopic maneuvers are not possible or ineffective.
