What is the relationship between free flow and pressure flow studies in women?

Introduction And Hypothesis: The relationship between free flow (FFS) and pressure flow (PFS) voiding studies remains uncertain and the effect of a urethral catheter on flow rates has not been determined. The relationship between residuals obtained at FF and PFS has yet to be established.

Methods: This was a prospective cohort study based on 474 consecutive women undergoing cystometry using different sized urethral catheters at different centres.

Effect of prolapse repair on voiding and bladder overactivity.

Purpose Of Review: To determine the effects of repair of pelvic organ prolapse (POP) on detrusor overactivity, overactive bladder (OAB) symptoms and voiding function. Understanding the cause of OAB in women with prolapse gives us more insight into the cause of detrusor overactivity and OAB in general. Understanding the different causes involved in OAB will allow us to target our treatments more effectively.
