Trends in ureteral surgery on an academic gynecologic oncology service.

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.

Ureterocalicostomy: a contemporary experience.

OBJECTIVES: To report our contemporary experience with ureterocalicostomy to determine whether the indications or results have changed in modern practice. Ureterocalicostomy is a well-established treatment for patients with complicated ureteropelvic junction (UPJ) obstruction and other forms of proximal ureteral obstruction. Although both retrograde and antegrade endourologic interventions have become accepted forms of management, the success rates do not approach those of open or even laparoscopic interventions, potentially leading to a greater number of patients with treatment failure and the need for more complicated reconstruction. METHODS: Between July 1991 and February 2004, 11 patients (4 women and 7 men), aged 19 to 68 years (mean 38), underwent open surgical ureterocalicostomy. The indications for surgery were primary UPJ obstruction in 4, failed cutting balloon incision for UPJ obstruction in 3, proximal ureteral stricture after ureteroscopic stone removal in 2, and obliterated UPJ after percutaneous nephrolithotomy and failed antegrade endopyelotomy in 1 patient each. RESULTS: Hospitalization ranged from 4 to 7 days (mean 5.1). No patient experienced a significant perioperative complication. With follow-up ranging from 5 to 32 months (mean 10.1), relief of obstruction was evident in all patients as documented by intravenous urography or nuclear renography. Furthermore, differential function on the involved side improved from a mean of 54.6% preoperatively to 60.1% postoperatively (P <0.05). CONCLUSIONS: The spectrum of indications for ureterocalicostomy has changed, although excellent results can still be achieved. Although laparoscopic approaches are currently being evaluated, most patients currently undergoing this reconstructive procedure still require open operative intervention.
