- Scientific TitleDynamics of male pelvic floor contractions through transperineal ultrasound imaging in continent and incontinent patients after radical prostatectomy.
- ACRONYMN/A
- hypothesis1. To investigate the intra- and interreliability of transperineal ultrasound measurements of the displacement of multiple points along the urethra in men after radical prostatectomy;
2. To compare the relative displacement of urethrovesical junction, anorectal junction and distal urethra during voluntary pelvic floor muscle contractions from preoperative to 3 months postoperative after radical prostatectomy;
3. To compare the relative displacement of urethrovesical junction, anorectal junction and distal urethra during voluntary pelvic floor muscle contractions between continent and incontinent men after radical prostatectomy.
- Healt Condition(s) or Problem(s) studiedUrinary incontinence, Transperineal ultrasound, Radical prostatectomy
- Inclusion criteriaContinent patients:
1. Patients who will have a radical prostatectomy for localised or locally advanced prostate cancer in the University Hospital Gasthuisberg in Leuven;
2. Patients who can participate in one pre- and one postoperative transperineal ultrasound measurement in the University Hospital Gasthuisberg.

Incontinent patients:
1. Patients who had a radical prostatectomy in the University Hospital Gasthuiberg, minimally 1 year before and are still urinary incontinent;
2. Patients willing to participate in one transperineal ultrasound measurement.
- Exclusion criteriaPatients who don't want to participate to the study.

- planned startdate 1-dec-2012

- Target number of participants16
- InterventionsBoth groups will have transperineal ultrasound.
Group 1: Patients who are planned for a radical prostatectomy will have a transperineal ultrasound of the displacement of multiple points along the urethra pre- and postoperatively.
Group 2: Patients who had a radical prostatectomy minimum one year before and are still incontinent will have a transperineal ultrasound of the displacement of the same multiple points along the urethra.
- Primary outcomeTo investigate if the displacement of the anorectal junction, ventral and dorsal urethrovesical junction, dorsal point of the bulbus and dorsal point of the striated urethral sphincter have a good intra- and interrater reliability.
- Secondary outcomeTo compare the displacement of the different structures of urinary continent and incontinent men after radical prostatectomy.
- TimepointsGroup 1 (continent men): Preoperatively and 3 months postoperatively;
Group 2 (incontinent men): Minimum 1 year postoperatively.

- PublicationsN/A
- Brief summaryProstate cancer is the most common cancer in men on this moment. Radical prostatectomy is since many years the gold standard for eradication of localized prostate cancer. Urinary incontinence however remains one of the most embarrassing complications after prostatectomy. This project aims to investigate the underlying causes of urinary incontinence by visualising the displacement of several points along the urethra, while contracting the pelvic floor, with transperineal ultrasound.
