The effects on vesicourethral function following laparoscopic hysterectomy.
The aim of our study is to determine whether laparoscopic hysterectomy is associated with increased postoperative urinary symptoms and to assess the change in urodynamic parameters after operation. Forty-five women were arranged for laparoscopic hysterectomy (LH). Each patient received urinalysis, interview, and urodynamic study including uroflowmetry, filling and voiding cystometry and urethral pressure profilometry before and after hysterectomy. A total of 27 patients (60%) had urinary symptoms preoperatively. After operation, only 22 patients (48.9%) remained symptomatic. There was no significant change in the number of women with one or more voiding symptoms before and after surgery, but the incidence of urinary frequency and stress incontinence decreased significantly after laparoscopic hysterectomy (P < 0.05). In addition, maximal urethral closure pressure and maximal cystometric capacity showed significant increases after operation. They were 73.1 cm H2O (range: 49-114) vs 104.4 cm H2O (range: 60-147) (P < 0.001), and 363.3 ml (range: 287-423) vs 396.1 ml (range: 265-515) (P < 0.001), respectively. The result indicated that laparoscopic hysterectomy did not significantly increase the subjective or objective incidence of vesicourethral dysfunction. On the contrary, some patients might be cured of urinary frequency or stress incontinence postoperatively.
