Hysterectomy and lower urinary tract symptoms: a nonrandomized comparison of vaginal and abdominal hysterectomy.

BACKGROUND/AIMS: It has been reported that lower urinary tract symptoms (LUTS) are more prevalent in patients who have undergone hysterectomy. However, the effects of surgical approach of hysterectomy on micturition have not been well documented. The aim of this study is to compare LUTS between patients who underwent vaginal and abdominal hysterectomy.

METHODS

Prospective observational study among 430 patients undergoing vaginal or abdominal hysterectomy for benign disease other than genital prolapse. Participating patients completed a validated disease-specific questionnaire before surgery, 6 months and 3 years after surgery.

RESULTS

112 women underwent vaginal hysterectomy and 318 abdominal hysterectomy. After correction for differences in uterine size, descent of the uterus and other differences, LUTS were more common at 3 years after surgery following vaginal than following abdominal hysterectomy (OR 2.2, 95% CI 1.3-4.0). After adjustment for descent of the uterus, uteral size, parity and indication for hysterectomy, this difference was still statistical significant (adjusted OR 3.0, 95% CI 1.4-6.2).

CONCLUSION

As compared to abdominal hysterectomy, LUTS appear to be more common following vaginal hysterectomy.
