Insights
Early ureteroneocystostomy repair for iatrogenic ureteral injury showed similar outcomes to delayed repair. While early repair had more inpatient complications, long-term results for ureteral stricture recurrence were comparable between groups.
Area of Science:
- Urology
- Surgical Outcomes
- Medical Device Technology
Background:
- Iatrogenic ureteral injuries can occur during various surgical procedures.
- Ureteroneocystostomy is a common surgical technique for repairing ureteral defects.
- The optimal timing for surgical repair of these injuries remains a subject of investigation.
Purpose of the Study:
- To compare the outcomes of early (≤7 days) versus delayed (>7 days) ureteroneocystostomy for iatrogenic ureteral injuries.
- To evaluate the impact of repair timing on inpatient and post-discharge complications.
- To assess long-term outcomes such as stricture recurrence.
Main Methods:
- Retrospective review of billing data from 2012-2018.
- Inclusion of patients undergoing ureteroneocystostomy for surgical ureteral injuries.
- Categorization into early (≤7 days) and delayed (>7 days) repair groups.
- Statistical analysis of demographics, inpatient, and post-discharge data.
Main Results:
- Sixty-seven patients were included; 12 had early repair and 55 had delayed repair.
- Early repair group had significantly higher inpatient complications (58% vs 18%).
- No significant difference in 30- and 90-day complications or stricture recurrence was observed between groups.
Conclusions:
- Early and delayed ureteroneocystostomy for iatrogenic ureteral injuries yield comparable outcomes.
- While early repair is associated with higher initial inpatient complications, long-term functional results are similar.
- The timing of repair does not appear to significantly impact stricture recurrence.
Objective:
To compare the outcomes of patients who underwent early repair (≤7 days) of iatrogenic ureteral injury with ureteroneocystostomy and compare them to those repaired in a delayed fashion (>7 days).
Methods:
A retrospective review of billing data between 2012 and 2018 identified patients who underwent ureteroneocystostomy for a benign ureteral disease. Inclusion criteria included all ureteral injuries related to a laparoscopic, robotic, or open surgical injury. Patients with ureteral injury related to radiation, stones, or reconstructive surgery were excluded. Patients undergoing reconstruction during the initial injury or within ≤7 days were designated as having undergone early repair, while the remaining were considered delayed repair. Demographics, as well as inpatient and postdischarge data were acquired, and statistical analysis was performed comparing the 2 groups.
Results:
Sixty-seven patients met inclusion criteria. Early repair was performed on 12 patients, while 55 underwent delayed repair. No significant difference in age, gender, Charlson Comorbidity Score, laterality, stricture location, or history of pelvic/abdominal radiation was noted. Inpatient complications were significantly higher in the immediate group (58 vs 18%, P =.004). Thirty- and 90-day complications were similar. Two patients in the delayed group and none in the immediate group demonstrated stricture recurrence (P =.710). A higher rate of Boari flap ureteral reconstruction was performed in the delayed cohort (P =.001).
Conclusion:
In this cohort, there was no detectable difference in outcomes when comparing early and delayed ureteroneocystostomy for iatrogenic ureteral injuries.
