Urodynamic changes following laparoscopic versus vaginal hysterectomy

To compare urodynamic changes before and after hysterectomy (laparoscopic vs. vaginal approach) for benign gynecological diseases.

A total of 90 women with a mean age of 56.36-years were enrolled in this study between August 2019 and April 2021. They were divided into two equal groups (45 patients each). Group, I had a vaginal hysterectomy, and Group II had a laparoscopic hysterectomy. All patients were assessed clinically using ICIQ-FLUTS questionnaire and a uro-dynamic study before and six months after surgery.

Both vaginal and laparoscopic hysterectomy did not significantly change the maximum flow rate, voiding time, and average flow rate. The increase in residual urine volume in group I was not significant (p = 0.129), as was in Group II (p = 0.217). All the modifications, however, were within permis-sible limits. According to the cystometry result, volume at initial sensation rose in both groups after surgery, with no statistically significant difference (p = 0.364). After both forms of hysterecto-my, maximum bladder capacity did not vary considerably. Preoperatively, all study participants exhibited no overactivity of the detrusor muscle; nevertheless, following surgery, overac-tivity was noted in 9 patients after vaginal hysterectomy com-pared to three patients after laparoscopic hysterectomy, and all the alterations were within a clinically acceptable range. In addition, the ICIQ-FLUTS score was not significantly different between the study groups.

According to the urodynamic study, hysterectomy for benign uterine conditions, whether vaginal or laparoscopic did not adversely affect urinary bladder function.
