Objective: To identify clinical features of urinary tract injuries detected during or after gynecologic surgeries, with a specific focus on incidence and role of surgeon and surgical route on urinary injury.

Study design: The institutional database from January 2009 to January 2017 was reviewed with respect to gynecologic (non-obstetric) surgeries and urinary injuries.

Results: A total of 8719 gynecologic surgeries were identified. Of these, 46 (0.52%) were found to be complicated with a bladder (N=34, 0.38%), ureteral (N=11, 0.12%) and/or urethral injury (N=1, 0.01%). Bladder injuries occurred mostly at the superior part of the bladder, while ureteric injuries at the most distal part of the ureter. Ureteric injuries were mostly delayed (81.8% vs. 5.9%, P<0.001) and were more related to thermal injury than bladder injuries (45.5% vs. 8.8%, P=0.029). Among all surgical procedures, radical hysterectomy had the highest incidence for the ureteric injury (8.53%), while Burch colposuspension via minimally invasive route had the highest incidence for the bladder injury (16.6%). Cumulative incidence of urinary injury significantly differed according to the surgical route preferred (P=0.032), with the vaginal surgeries were associated with the highest incidence (0.96%). However, there was no such a difference in injury rates between the low-volume (0.55%) and high-volume (0.52%) surgeons (P=0.328)

Conclusion: Overall incidence of lower urinary tract injury at gynecologic surgeries is low, does not differ according to annual number of surgeries performed, but increases with the vaginal surgeries.
