Effect of Radical Prostatectomy on Involuntary Pelvic Floor Muscle Contraction
Effect of Radical Prostatectomy on Involuntary Pelvic Floor Muscle Contraction
This study evaluate the effect of radical prostatectomy on involuntary pelvic floor muscle
 contraction
Radical prostatectomy may cause stress urinary incontinence (SUI). That poses problem in
 terms of quality of life. There are many treatment options available for patients with SUI,
 but the exact mechanism is not known. We compared, in continent and incontinent men
 post-radical prostatectomy, the correlation between the temporal course of pelvic floor
 activation during cough.

 Simultaneously, recordings of electromyographic activity of external anal sphincter (EAS EMG)
 and external intercostal muscle (EIC EMG) during coughing will be made with a pair of
 pre-gelled electrodes. Cough effort cause an involuntary pelvic contraction. Intercostals
 muscles recording was chosen because they are one of the muscular components of cough
 initiation with diaphragm muscle. 24h pad-weighing test is used to quantify urinary
 incontinence. We will measure the latency between the onset of the EIC EMG and the EAS EMG
 (RT3), during a cough effort. We will also measure the duration of the contraction, the
 maximum EAS EMG activity and the area under the curve.
