SIMS is a multi-centre randomised controlled trial, funded by the NIHR HTA Programme, of surgical options for the management of female stress urinary incontinence (SUI).  The aim of this trial is to evaluate the clinical and cost effectiveness of adjustable anchored Single Incision Mini-Slings (SIMS) compared to tension-free Standard Mid-urethral Slings (SMUS). 

SIMS recruited 600 women.  Trial participants will be followed-up for 36 months.

The primary outcome measure will be patient-reported success rate measured by the validated PGI-I (a 1-item questionnaire designed to assess the patient’s impression of changes in her urinary symptoms) at 12-months.

SIMS is led by Professor Mohamed Abdel-Fattah based at the University of Aberdeen.
