Abstract

Objective: To compare the efficacy of needleless mini-sling placed either retropubic (U-shape) or trans-obturator (hammock-shape) to treat stress urinary incontinence.

Setting: One hundred and twenty six women were randomized in a 2:1 ratio to receive hammock-shaped or U-shaped of Contasure-NDL.

Methods: All surgical procedures were performed by one senior surgeon experienced in anti-incontinence surgery with mesh. Cough-stress test was considered for objective outcome. Subjective outcomes consisted of International Consultation on Incontinence Questionnaire Short Form (ICIQ-SF), Patient Global Impression of Improvement (PGI-I) and three-item Likert scale to measure satisfaction. Assessments were performed preoperatively and at postoperative 6th, 12th and 18th month.

Results: The objective cure rates at postoperative 6th and 12th month were significantly lower in U-shape group compared to hammock-shape group (85.4 vs. 96.4%; p = 0.034) and was comparable with hammock-shape group at 18th month postoperative (90.2 vs. 96.4%, respectively; p = 0.216). The subjective cure rates at postoperative 6th, 12th and 18th month were similar between groups (90.2/90.2/100% vs. 96.4/96.4/96.4%, respectively; p > 0.05). Median of total ICIQ-SF scores was significantly lower in hammock-shaped group (1.62 ± 2.92) compared to U-shape (3.80 ± 2.64) at 18th month (p < 0.001). The rate of patients reported as very satisfied or satisfied to the Likert scale was 90.2% in U-shape group and 96.4% in hammock group. Patients' responses to PGI-I were majorly distributed to "much better" and "very much better" with a mean score of 1.93 ± 2 in U-shape and 1.33 ± 1 in hammock group at 18th month of follow-up (p < 0.001).

Conclusion: U-shape placement of needleless single-incision mini-sling mimicking the retropubic route did not satisfy in achieving the patient's goal when compared to hammock-shape placement.
