Urethral Functional Profile Length Before Radical Prostatectomy as an Early Postoperative Continence Predictor

February 15, 2022 updated by: Mirko Bakula, Clinical Hospital Centre Zagreb

Urinary incontinence (UI) is one of the most common complications of radical prostatectomy (RP). Impaired urethral sphincter function is generally considered to be the most important contributing factor of UI however, the mechanism of onset and recovery of urinary continence has not been fully elucidated. In this research, the urodynamic method of Urethral Pressure Profile (UPP) was used to evaluate Functional Urethral Length (FUL) and Maximal Urethral Closure Pressure (MUCP) and correlate with the postprostatectomy continence recovery. Objective of this research is to evaluate preoperative FUL and MUCP as an early continence recovery predictors after open retropubic RP (ORRP).

The research was conducted at the Department of Urology of the University Hospital Centre Zagreb on a group of 43 patients in the period from July 15th , 2019 to May 07th , 2021.The severity of UI and bothersome were assessed using fully validated International Consultation on Incontinence Questionnaire - Urinary Incontinence Short Form (ICIQ-UI SF) and number of pads used in 24h. Patients were interviewed about the use of urinary pads and asked to fill out the ICIQ-UI SF before and 2, 8, 16 and 24 weeks after RP.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Patients with prostate cancer
We performed urethral pressure profilometry prior to open retropubic radical prostatectomy (ORRP). Patients were interviewed about the urinary incontinence by the usage of pads and International Consultation on Incontinence Questionnaire-Urinary Incontinence Short Form (ICIQ-UI SF) prior to ORRP and at 2, 8, 16 and 24 weeks after ORRP.
Procedure: Profilometry
Profilometry was performed in 43 patients before open retropubic radical prostatectomy.
Other Names:
  • Urethral pressure profile measurement

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Functional Urethral Length as a predictor of Urinary Incontinence
Time Frame: 24 weeks
Functional Urethral Length (FUL) is measured using Urethral Presssure Profilometry and expressed in mm. The severity of urinary incontinence and bothersome were assessed using fully validated International Consultation on Incontinence Questionnaire - Urinary Incontinence Short Form (ICIQ-UI SF) and number of pads used in 24h. Patients were interviewed about the use of urinary pads and asked to fill out the ICIQ-UI SF before and 2, 8, 16 and 24 weeks after radical prostatectomy. ICIQ-UI SF score ranges: min 0, max 21 (higher score indicating greater severity of symptoms). Cut-off for positive UI, in this research, was 6. Cut-off for positive UI by number of pads used per day was 2.
24 weeks
Maximum Urethral Closure Pressure as a predictor of Urinary Incontinence
Time Frame: 24 weeks
Maximum Urethral Closure Pressure (MUCP) is measured using Urethral Presssure Profilometry and expressed cmH2O. The severity of urinary incontinence and bothersome were assessed using fully validated International Consultation on Incontinence Questionnaire - Urinary Incontinence Short Form (ICIQ-UI SF) and number of pads used in 24h. Patients were interviewed about the use of urinary pads and asked to fill out the ICIQ-UI SF before and 2, 8, 16 and 24 weeks after radical prostatectomy. ICIQ-UI SF score ranges: min 0, max 21 (higher score indicating greater severity of symptoms). Cut-off for positive UI, in this research, was 6. Cut-off for positive UI by number of pads used per day was 2.
