OBJECTIVE: To assess the effect of laparoscopic hysterectomy (LH) on the mobility and position of bladder neck (BN) and urinary symptoms. DESIGN: We assessed the BN and urinary symptoms of 151 patients by introital ultrasonography and questionnaires before and after LH. SAMPLE: One hundred and fifty-one women who underwent LH from June 1999 to June 2001. RESULTS: A significant decrease was noted in the number of women exhibiting one or more urinary symptoms from 81 (53.6%) preoperatively to 58 (38.4%) postoperatively (P < 0.01). The incidence of urinary frequency, mild stress incontinence and nocturia decreased significantly after laparoscopic hysterectomy (P < 0.01). Changes in other urinary symptoms following hysterectomy showed no statistical significance (P > 0.05). During straining, the postoperative position of the BN localised more dorsally (P < 0.01) and the ventral mobility of the BN decreased significantly following surgery (P < 0.05). There was no significant difference in the location of the BN with respect to the pubis at rest and during straining, in the cephalocaudal direction, before and after hysterectomy (P > 0.05). CONCLUSION: Some patients experienced a substantial improvement of preoperative urinary symptoms following LH, partly as a result of a decrease in the hypermobility of BN.
