Objective: To describe the incidence, complications, and trends associated with ureteral surgeries on a gynecologic oncology service in the context of a fellowship training program over a 24-year period.
Methods: We conducted a retrospective cohort analysis of ureteral surgeries by gynecologic oncologists at either Moffitt Cancer Center or Tampa General Hospital from 1997 to 2020. Patient characteristics, predisposing factors, location and type of injury, repair method, postoperative management and complications were abstracted from the medical record. The recent cohort (2005-2020) was compared to our prior series (1997-2004).
Results: Eighty-eight cases were included. The average number of ureteral surgeries per year decreased from 5.75 (1997-2004) to 2.63 (2005-2020). Of 46 iatrogenic injuries, 45 were recognized and repaired intraoperatively. Ureteral transection was the most common type (85% [39 of 46]) and the distal 5 cm was the most common location of injury (63% [29 of 46]). Ureteroneocystostomy was the most common method of repair (83% [73 of 88]). Postoperative management, including stenting and imaging, has not changed significantly. Length of urinary catheter usage decreased in the recent cohort without associated complications. Five patients had major postoperative complications and 4 involved the urinary tract. Of those with follow-up, 96% (66 of 69) of ureteroneocystostomies and 75% (9 of 12) of ureteroureterostomies had radiologically normal urinary tracts.
Conclusions: Ureteral surgery is necessary in the case of injury or involvement with invasive disease. There has been a decrease in number of procedures. Ureteroneocystostomy has remained the most common method of reconstruction for both injury and resection with acceptable postoperative complication rates.
