Comparison of Urodynamic Evaluation in Post-Radiation Salvage Prostatectomy Versus Prostatectomy-only Patients
You will come to the urology clinic for 1 visit. At this visit, a video urodynamics test
will be performed. The urodynamics test is used to check bladder and urinary function using
pressure and volume measurements with x-ray images.
Pressure-monitoring catheters will be inserted into your bladder and rectum, and your
bladder function will be checked as the bladder is slowly filled with fluid. Measurements
will then be made of your bladder capacity (the volume of urine the bladder can hold),
bladder and abdominal (stomach) pressures, and bladder compliance (the bladder's ability to
hold urine) throughout the course of this study. This procedure will take about 90 minutes
After the urodynamics test is completed, you will complete a questionnaire about your
urinary function and your quality-of-life (regarding daily living after surgical treatment
for prostate cancer). The questionnaire will take about 30 minutes to complete.
If you have had urodynamic testing with Dr. Westney within the past year, we would like your
consent to use the data from that test, and also for completion of the questionnaire
mentioned in the previous paragraph. You will complete this informed consent and
questionnaire being sent with a return envelope and will not need to come to the urology
clinic for a visit.
Length of Study:
Once you have completed the urodynamics testing and questionnaire, your participation on
this study is complete.
This is an investigational study. The video urodynamics test is approved by the FDA and
commercially available. Up to 50 patients will take part in this study. All will be
enrolled at M. D. Anderson.
Observational Model: Case Control, Time Perspective: Prospective
Comparison of Urodynamic Changes Related to Radiation Post Salvage Prostatectomy versus Prostatectomy Only
Comparison of urodynamic changes related to radiation by performing urodynamics (measurement of bladder pressure, electrical activity, and radiographic imaging) in patients post salvage prostatectomy versus prostatectomy only, using a 2-sample t-test to test for differences between the 2 groups of men with respect to urodynamic score.
