Urodynamic evaluation after abdominal hysterectomies for gynecological malignancies

The aim of this study was to evaluate the effect of abdominal hysterectomy made for gynecological malign diseases on lower urinary tract functions in asymptomatic patients by preoperative and postoperative urodynamic measurements. Thirty four asymptomatic women, who were operated for gynecological malignancies by abdominal hysterectomy from September 2008 to June 2009, in Dicle University Hospital Department of Obstetrics and Gynecology, were included in this study. Urodynamic measurements were performed before the operation and in the sixth week of surgery. No statistically significant changes were detected in first urge, normal urge, and strong urge, bladder capacity before and after surgery. The evaluation of functional urethral length showed a significant difference by UPP between pre and postoperative values (p = 0.003). The decreases in values of the maximum urethral pressure and the maximum urethral closing pressure were significant (p = 0.004 and p = 0.048). The voiding time was found to be statistically increased (p = 0.002), voided volume and residual urine volume were remained unchanged. There were no significant differences in other measurements. Preoperative and postoperative urodynamic studies are necessary to determine and cure urinary dysfunctions caused by abdominal hysterectomy.
