Objective To determine age-adjusted rates (AAR) of lower urinary tract (LUT) injury and incidence in selected inpatient gynecologic and obstetric procedures. Study Design We utilized the National Hospital Discharge Survey, 1979–2006. AAR of non-obstetric bladder and ureteral injuries and incidence of LUT injury for various hysterectomy types and deliveries were calculated for women > 18 years old. Results Overall AAR of ureteral injury decreased from 0.06 to 0.03 per 1000 women (1979–2006). AAR of inpatient gynecologic procedures decreased from 24.9 to 11.8 per 1000 women (1979–2006). By hysterectomy type, bladder injury was highest in LAVH (13.8 per 1000) and VH (13.1 per 1000). Ureteral injury recognized during hysterectomy was most common with radical hysterectomy (7.7 per 1000) and least common with LAVH (0 per 1000). Conclusions Ureteral injuries at time of inpatient surgical procedures have decreased from 1979–2006. This corresponds with a sharp decrease in inpatient gynecologic procedures.
