(HealthDay News) — At five years after surgery, women undergoing subtotal abdominal hysterectomy (SAH) were more likely to have urinary incontinence (UI) than those undergoing total abdominal hysterectomy (TAH), according to a study published in the May issue of BJOG: An International Journal of Obstetrics and Gynaecology.
Lea Laird Andersen, MD, from Nykøbing Falster Hospital in Denmark, and colleagues compared the rates of UI and other complications at five years after SAH or TAH. Women with benign uterine diseases scheduled for abdominal hysterectomy were randomized to SAH (161 women) or TAH (158 women). Follow-up data were collected using postal questionnaires sent out five years after surgery (73.4% response rate).
The researchers found that at five years after surgery, a significantly higher proportion of patients had UI after SAH vs. TAH (30.1 vs. 17.6%; relative risk, 1.71; 95% confidence interval, 1.06–2.75; P=0.026). After multiple imputation to account for missing data, this difference was attenuated (relative risk, 1.37; 95% confidence interval, 0.99–1.89; P=0.052). In the SAH group, 11% of women still experienced vaginal bleeding.
“We observed that more women were urine incontinent five years after SAH than after TAH and that 11% of the women in the SAH group still experienced vaginal bleeding,” the authors write.
