Aim: Stress urinary incontinence (SUI) is accompanied by pelvic organ prolapse (POP) in many cases. We investigate a procedure to adjust the level of suspension of the mid-urethra using tension-free vaginal tape (TVT) under general anesthesia at the time of POP repair surgery.
Methods: Preliminary examination carried out prior to this study showed that the pressure stress applied by a surgeon is less than half of that induced using the cough-stress method: the manual-tapping method (MTM) showed an average intravesical urinary leak point pressure (IULPP) of 21.4 mmHg (range 19-23 mmHg), when the cough-stress method demonstrated an average IULPP >52.4 mmHg (range 45-58 mmHg; n = 3). An attempt was made to predict postoperative SUI by packing sponge gauze into the manually replaced vagina preoperatively. If SUI appeared, TVT was added to the repair operation for POP in those patients (n = 11). Lastly, the MTM was used to decide the level of urethral suspension during the TVT procedure following POP repair surgery under general anesthesia (n = 11).
Results: Eleven patients underwent the TVT procedure combined with POP repair surgery. The mean postoperative follow-up period was 23.8 months (range 9-40 months). There was no case of post-surgical ischuria. One patient showed a cystocele during the postoperative course. However, all other patients were relieved from the symptoms of POP, and none complained of SUI following the procedure.
Conclusion: The MTM seems to be a more appropriate indicator by which to adjust the level of urethral suspension during the TVT procedure than the conventional method, particularly under general anesthesia. To prevent and cure perioperative SUI, the MTM as a TVT procedure combined with POP repair surgery under general anesthesia is a useful procedure.
