Sequential urodynamic assessment before and after laparoscopic sacrocolpopexy

Objective Controversial data are available as to whether to perform a simultaneous abdominal or vaginal colposuspension operation in laparoscopic sacrocolpopexy procedures. We wanted to evaluate the effect of a modified laparoscopic operation technique on urodynamic parameters and lower urinary tract symptoms. Design Prospective single center cohort study. Setting Teaching hospital. Population Forty-nine consecutive patients who underwent a modified laparoscopic sacrocolpopexy/hysteropexy operation using bone anchor fixation and synthetic mesh, performed by the same laparoscopic surgeons. Methods Pre- and postoperative multichannel urodynamic evaluation and validated questionnaires. The same urologist, blinded to the results of the questionnaire survey, interpreted all urodynamic evaluations. Main outcome measures The effects of surgery on pelvic anatomy and patient satisfaction, urodynamic observations and diagnoses and symptom scores in validated questionnaires. Results Forty-two patients consented to pre- and postoperative urodynamic evaluation. Laparoscopic sacrocolpopexy successfully corrected vaginal vault prolapse in all 42 patients with urodynamic evaluation six months after surgery. The bladder volume at first desire to void was significantly increased and the maximal detrusor pressure at voiding phase was significantly decreased. In the questionnaires, irritative and storage voiding symptoms were significantly decreased. Conclusions The results of the study demonstrate that there are no adverse urodynamic findings following this modified technique for laparoscopic sacrocolpopexy. The statistically significant urodynamic improvements are in accordance with the scores on the Urogenital Distress Inventory questionnaires. These results do not support a simultaneous routine prophylactic colposuspension procedure.
