Abstract
The aim of this study was to compare the clinical outcomes of anti-incontinence surgeries employing the transobturator sling and single-incision sling (SIS). Our hypothesis is that the outcome of the SIS is not inferior to the obturator sling. This retrospective study reviewed the medical records of patients who underwent anti-incontinence surgery with the transobturator sling or SIS from July 2005 to November 2014. Patients who underwent concomitant pelvic organ reconstruction with an artificial mesh were excluded. Assessments included preoperative and postoperative urodynamic examinations, perioperative complications, and postoperative urogenital symptoms. A total of 122 women were recruited according to the inclusion and exclusion criteria. Among them, 68 patients underwent transobturator sling procedures while 54 patients underwent SIS procedures. The subjective failure rate of the transobturator sling and SIS were 10.2% and 18.5%, respectively (p = 0.292). The objective failure rate, defined as a pad test showing more than 2 g of urine, was 10.2% for the transobturator sling and 12.9% for the SIS (p = 0.777). SIS resulted in less blood loss, operative time, length of hospital stay, and transient voiding dysfunction after the operation. No major complication occurred after either surgical intervention. In conclusion, SIS and transobturator slings might have similar efficacy, safety, and effects on new-onset urogenital symptoms.
