(HealthDay News) — In 2001 to 2010, 0.5% of women experienced ureteric injury in the year after a hysterectomy, with lower rates for benign versus malignant conditions and rates of injury increasing between 2001 and 2010, according to a study published online in BJOG: An International Journal of Obstetrics and Gynaecology.
Amit Kiran, Ph.D., from the London School of Hygiene & Tropical Medicine, and colleagues examined the rates of ureteric injury among women undergoing hysterectomy in a retrospective cohort study. The main outcome measure was ureteric injury within 1 year of hysterectomy.
The researchers found that 377,073 women underwent hysterectomy in 2001 to 2010, of whom 0.5% experienced a ureteric injury. The rate of injury was higher in 2006-2010 than in 2001-2005 in both benign and malignant groups. After 2006, ureteric injuries were most common for abdominal radical hysterectomy for uterine cancer (10.7%). For ovarian and cervical cancer, the proportion of women having ureteric injury was similar (1.9 to 4%, depending on the procedure type). The rate of injury tended to be lower for benign conditions (less than 1%). Among this group, women with endometriosis had the highest risk (1.7% after total abdominal hysterectomy).
“The risk of ureteric injury within 1 year of hysterectomy varied by type of hysterectomy for benign and malignant condition,” the authors write.
