Brief summary

Design outcomes

Primary

MeasureTime frameDescription
Abnormal Bladder Function1 year post operativeAbnormal post-operative bladder function a composite outcome assessed at 12 months after surgery. It is one or more of the following: 1) significantly bothersome stress incontinence or over active bladder symptoms after surgery as measured by questions 1, 2, 3 of the Urogential Distress Inventory (UDI-6) 2) a positive cough stress test in the office, 3) re-treatment for stress urinary incontinence (repeat surgery or pessary use), 4) post-operative urinary retention (presence of self-catheterization at 6 weeks post-operatively or beyond, or therapeutic intervention for retention at any time during the 12 months after, such as pelvic floor physiotherapy, sling lysis, urethrolysis, or sacral nerve stimulation.

Secondary

MeasureTime frameDescription
Rate of discharge from hospital with on-going need for catheterization12 months
Duration of catheterization after surgery12 months
Questionnaire scores12 monthsstandardized questionnaire scores (UDI-6, Incontinence Impact Questionnaire, International Consultation on Incontinence Modular Questionnaire)
Pad test12 monthStandardized 1 hour pad test values
