To identify if the short term association of pressure flow rates with resolution of overactive bladder (OAB) is maintained in the long term in patients with mixed urodynamic incontinence treated with a retropubic midurethral sling. To assess if other demographic factors are associated with the long term resolution of OAB.
This was follow up study of a consecutive case series of 100 patients treated with a MUS at a single center followed up with questionnaires. Preoperative pressure flow studies were compared to the resolution of urgency and urgency incontinence after surgery.
A total of 6.25 years after surgery, resolution of urgency and urgency incontinence was associated with a higher preoperative flow rate (26.7 mL/s vs 19.1 mL/s P = 0.02) and a higher flow rate centile (33.1 vs 14.0 P = 0.01). No other demographic parameters were associated with resolution of OAB.
The long term outcome and resolution of urgency and urgency incontinence can be predicted by preoperative pressure flow studies over 6 years after surgery.
