Assessing the readjustable sling procedure (Remeex system) for female stress urinary incontinence with detrusor underactivity

Purpose: Many surgeons worry about postoperative voiding problems in patients with stress urinary incontinence (SUI) and detrusor underactivity (DU). This study hypothesized that adjusting the tension after surgery would benefit patients with DU, and therefore researchers evaluated the outcomes and quality of life of women with SUI and DU who underwent the readjustable sling procedure (Remeex). Methods: The medical records of 27 patients who were treated with the Remeex system for SUI and DU between 2007 and 2013 were retrospectively analyzed. The incontinence visual analogue scale (I-VAS), incontinence quality of life questionnaire (I-QOL) and the Sandvik incontinence severity index (ISI) were used to evaluate the efficacy of the Remeex system both prior to surgery and at the last visit after surgery. The treatment was considered successful if there was no urine leakage based on the Sandvik questionnaire. Results: The mean follow-up period was 38.0 months (range, 1-75 months), and the treatment success rate was 81.5%. Despite no urine leakage, 7 patients wanted the Remeex system to be removed due to persistent postoperative urinary retention within a year of surgery. One patient underwent a long-term adjustment under local anesthesia 6 years after the initial surgery. The I-VAS, ISI and all domains of the I-QOL scores improved significantly postoperatively and the maximum flow rate decreased significantly after the procedure. However, the postvoid residual did not change significantly. Conclusions: The Remeex system provided a good cure rate and improved the quality of life of women with SUI and DU. Therefore, the Remeex system should be considered as a treatment option for female patients with concomitant SUI and DU.
