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.

Inclusion Criteria:

1. Patients diagnosed with localized prostate cancer
2. Open Retropubic Radical Prostatectomy (ORRP) is planned as a treatment

Exclusion Criteria:

1. Incontinent patients prior to ORRP
2. Previous surgery in the area of the prostatic urethra
3. Previous procedures that can damage the innervation of the pelvis
4. Radiotherapy performed in the pelvic area prior to ORRP
5. Adjuvant radiotherapy in the first postoperative year

Patients enrolled in the study have prostate cancer.

IPD that underlie results in a publication (Urethral Pressure Profilometry results, ICIQ-UI SF scoring charts and urinary pads usage) will be available upon the request to Principal Investigator
