Urodynamic evaluation of lower urinary tract function in relation to total abdominal hysterectomy

This study was performed to evaluate lower urinary tract functions in asymptomatic patients by urodynamic measurements after total abdominal hysterectomy and bilateral salpingo-oophorectomy. Twenty asymptomatic patients who had undergone hysterectomy for benign diseases were included in the study and urodynamic measurements were performed before and 6 weeks after total abdominal hysterectomy and bilateral salpingo-oophorectomy. There was no postoperative difference in first urge, normal urge, urgency and maximum bladder capacity but average urethral length, functional urethral length and maximum urethral closing pressure were decreased and also bladder discharging time was increased. Voided volume and residual urine volume were unchanged. It was concluded that total abdominal hysterectomy and bilateral salpingo-oophorectomy did not change the postoperative bladder loading functions in asymptomatic patients but that significant changes occurred in urethral functions.
