Total trans-obturator tape (TOT) removal; a case series including pain and urinary continence outcomes.

INTRODUCTION AND HYPOTHESIS: For many years, mid-urethral mesh tape (MUT) was the gold-standard procedure for management of stress urinary incontinence (SUI). However, significant concerns were raised over its safety. We present a case series of total trans-obturator tape (TOT) removals, performed in a tertiary unit over a 3-year period. We aim to evaluate improvement of pain and change in urinary continence symptoms following mesh explantation.

METHODS

This is a retrospective case series of the outcomes of total TOT removal. Primary outcome is the change in pain scores following total removal, assessed preoperatively, at discharge and follow-up. Secondary outcomes were perioperative complications, including return to theatre, re-admission rates and incidence of worsening SUI and overactive bladder symptoms (OAB) postoperatively. Statistical analyses were performed using SPSS 27.0 package (IBM, Chicago, IL) and the GraphPad Prism 9 statistical packages.

RESULTS

Nineteen women were identified. Mean age was 52 years and mean BMI was 31. Indications for mesh removal were: chronic pain (95%), vaginal exposure (37%) and pelvic sepsis (5%). No patients had return to theatre. Median intraoperative blood loss was 200 ml (interquartile range [IQR]: 150-288). Mean length of mesh excised was 22 cm. Mean postoperative hospital stay was 2 days. At follow-up, most patients (72%) reported "improvement" of their mesh-related pain at follow-up, while 6% reported "worsening" of pain. Eighty-three per cent of patients reported worsening SUI, and 50% reported worsening OAB symptoms.

CONCLUSIONS

In the absence of sepsis, significant intraoperative complications are rare during total TOT removals. While 72% of patients reported improvement of their mesh-related pain, 6% still reported worsening pain after total mesh excision.
