Mechanism of Incontinence Before and After Genital Prolapse Surgery
Since year 2003, Glostrup/Herlev Hospital has devised a novel technique, urethral pressure reflectometry (UPR), for measurements of pressure and cross-sectional area in the female urethra. UPR has been able to separate continent women from women with stress urinary incontinence (SUI, defined by involuntary leakage during increased abdominal pressure). The method stands alone in its field.
9.5 % of all women undergo genital prolapse surgery during their lives (genital prolapse is characterized by a portion of the vaginal canal protruding from the opening of the vagina). However, 10-30 % of these women develop SUI after surgery, while approximately 40 % with preoperative SUI actually experience an improvement in their condition. Efforts have been made to predict the likelihood of a patient having SUI after genital prolapse surgery; however the tests have shown disappointing positive and negative predictive values.
A mid-urethral sling is gold standard for treatment of SUI and to avoid SUI after genital prolapse surgery, some clinics choose to treat all their patients with a sling, simultaneously. However, not all patients with SUI require surgery and the sling is associated with some risks, such as bleeding and bladder injury. There is no international consensus on the use of mid-urethral slings in women undergoing genital prolapse surgery. Thus, there is great need for knowledge and know-how regarding the mechanism of continence in women with genital prolapse, before and after surgery.
The hypothesis is that UPR may be used to uncover the changes in the female urethra before and after genital prolapse surgery, revealing significant differences in the parameters in women who develop SUI after surgery. UPR may become an important tool in the preoperative assessment, helping clinicians give better information and guidance to their patients.
