Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
Conservative treatment methods include pelvic floor muscle exercises (PFME) with or without biofeedback (BF), anal and perineal electrical stimulation (ES), magnetic stimulation (MS), compression (penile clamps), lifestyle changes and combinations of these methods (2).
ES artificially stimulates the pudendal nerve and its branches to cause direct and reflex responses of the urethral and periurethral striated muscles in women. ES also inhibits detrusor overactivity (3,4). There is conflicting evidence as to whether the addition of ES to treatment increases the efficacy of PFME alone in patients with UI after RP (Level of evidence:1b), (5). However, ES may benefit PFME for up to six months (Level of evidence: 2b), (5). Non-neurogenic male incontinence guidelines recommend PFME alone or in combination with BF and/or ES for men undergoing RP to accelerate improvement of UI (5).
Many studies have shown that anal ES alone (1,7,8) or in combination with PFME (4,9,10,11) is more effective than untreated (4,7,9,11) or placebo ES (8,12). There are only two randomised controlled trials in the literature evaluating the efficacy of perineal ES in patients with UI after RP (13,14). In the study by Yıldız et al. (13), the group receiving perineal ES and the control group receiving no treatment were compared in patients who developed UI after RP. The results showed that incontinence severity, incontinence episodes, quality of life and anxiety parameters improved significantly in the 8th week in the group receiving perineal ES compared to the control group. In the study by Pané-Alemany et al. (14), a group receiving perianal ES and a group receiving anal ES were compared in patients who developed UI after RP. In the study, it was shown that the efficacy of the two treatments was not statistically different.
Our study is the first prospective randomised controlled trial to evaluate the efficacy of perineal and anal ES added to PFME in patients with UI after RP. The aim of this study was to evaluate the efficacy of perineal ES and anal ES added to PFME on clinical parameters related to UI, quality of life and sexual functions, depression and anxiety. In addition, patients' preparation time for stimulation, treatment satisfaction and discomfort levels will be evaluated.

Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
The study included 93 patients (described in detail in the statistics section) who accepted the treatment among the male patients who applied to Pamukkale University FTR Polyclinic with the complaint of UI after RP or who were referred to the Urogynecological Rehabilitation Unit by the Urology outpatient clinic and who met the inclusion criteria. Patients will be informed about the content, purpose and application of the study and their written consent will be obtained.
At the beginning of the study, age, height, weight, education level, occupation, marital status, previous operations, systemic diseases, alcohol, tea, coffee, coffee, cigarette use and medications will be questioned in patients who applied to Pamukkale University FTR Polyclinic or Urology Polyclinic with the complaint of UI after RP and referred to the Urogynecological Rehabilitation Unit. The type of UI (stress, urge, mixed, drip) will be determined in all patients participating in the study.
Patients will be advised to continue their medical treatments for reasons other than incontinence during the treatment period. No lifestyle modification recommendations regarding urinary function will be given during the treatment period and participants will be instructed not to change their habits during the 8-week period of the study.
Ninety-three male patients who meet the inclusion and exclusion criteria after RP will be randomly divided into three groups using a random number table. The first group will receive PFME, the second group will receive PFME + anal ES, and the third group will receive PFME + perineal ES.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Group 1: PFME
The patients were instructed to do as an home exercise program in first 2 weeks, 5 s contraction and 10 s relaxation, including two sets of 5 repetition daily, in following 2 weeks 10 s contraction and 20 s relaxation, including two sets of 10 repetition daily, and after 4 weeks, 10 s contraction and 20 s relaxation including three sets of 10 repetition daily in three different position (lying, sitting, and standing). So in the first 2 weeks 30 contractions daily, in following 2 weeks 60 contractions daily and upward 4th weeks, 90 contractions daily with progressively increasing intensity was done. All patients were asked to mark the exercise at a daily home schedule. Patients who did not complete more than 20% of the list according to the daily home program were excluded from the study.

All patients were asked to mark the exercise at a daily home schedule. Patients who did not complete more than 20% of the list according to the daily home program were excluded from the study.
Group 2: PFME + Anal ES
Anal ES was applied in the lithotomy position by means of a combined electrotherapy (stimulation) device with anal electrodes. Anal ES was applied 3 days a week, 20 minutes a day, for a total of 24 sessions for 8 weeks. Stimulation parameters were 50 Hz frequency, 5-10 s work-rest cycle and 300 µs pulse amplitude. Symmetrical biphasic pulse wave was given in the range of 1-100 mA (according to the patient's discomfort level feedback). In this procedure, it was applied with an anal probe placed in the anal region. Patients did not perform voluntary contractions during ES. Anal probes were used separately for each patient. Anal ES sessions were performed by an investigator participating in the study. Men who missed any treatment session for the stimulation group were excluded from the study.
PFME + Anal ES
Anal ES was applied 3 days a week, 20 minutes a day, for a total of 24 sessions for 8 weeks.
Group 3: PFME + Perineal ES
Perineal ES was applied in the lithotomy position by means of a combined electrotherapy (stimulation) device with surface electrodes. Anal ES was applied 3 days a week, 20 minutes a day, for a total of 24 sessions for 8 weeks. Stimulation parameters were 50 Hz frequency, 5-10 s work-rest cycle and 300 µs pulse amplitude. Symmetrical biphasic pulse wave was given in the range of 1-100 mA (according to the patient's discomfort level feedback). In this procedure, five surface electrodes with a diameter of 2 cm will be used, four electrodes symmetrically in the perianal region and one electrode in the leg (ground-neutral electrode). Patients will not perform voluntary contractions during ES. Surface electrodes will be used separately for each patient. Perineal ES sessions were performed by an investigator participating in the study. Men who missed any treatment session for the stimulation group were excluded from the study.
PFME + Perineal ES
Perineal ES was applied 3 days a week, 20 minutes a day, for a total of 24 sessions for 8 weeks.
