  Purpose

To provide evidence of promising tests to noninvasively diagnose bladder outlet obstruction (BOO) in men with benign prostatic hyperplasia.

  1. Penile cuff test provides a means of obtaining a urodynamic diagnosis with a high level of accuracy without the morbidity and expense of invasive Pressure flow study.
  2. Penile cuff test may be particularly useful in the counseling of patients prior to benign prostatic hyperplasia operation. Patients diagnosed as obstructed following a penile cuff test can be reassured that surgery has a high chance of resulting in symptomatic benefit

Condition
Bladder Outlet Obstruction Pressure Flow Study

Study Type: Observational
Study Design: Observational Model: Cohort
Time Perspective: Prospective

Further study details as provided by KYU-SUNG LEE, Samsung Medical Center:

Primary Outcome Measures:
  • The Positive/Negative Predictive Value of Penile cuff test [ Time Frame: 5 hours ]
  • The proportion comparison of Good responder between obstructed and unobstructed patients in penile cuff test [ Time Frame: up to 3 months ]
    good responder: The reduction in the International Prostatic Symptom Scores of more than 50% from the initial scores 3 months after operation.


Secondary Outcome Measures:
  • The correlation of intra-vesical Pressure between Pressure flow study and penile cuff test [ Time Frame: 5 hours ]
  • The difference of Pain visual analogue scale score between two diagnostic tests [ Time Frame: 5 hours ]
  • The categorical change of penile cuff test normogram after BPH operation [ Time Frame: up to 3 months ]
  • The PSA level change after benign prostatic hyperplasia operation in obstructed and non-obstructed patients. [ Time Frame: up to 3 months . ]
  • The changes of International Prostatic Symptom Scores after BPH operation. [ Time Frame: up to 3 months ]

Estimated Enrollment: 193
Study Start Date: January 2014
