The Effect of Mobile-Based Perioperative Education on Urinary Incontinence and Erectile Function After Radical Prostatectomy

This prospective randomized controlled study aims to evaluate the effect of mobile-based perioperative education on postoperative urinary incontinence and erectile function in patients undergoing radical prostatectomy. Patients scheduled for radical prostatectomy will be assigned to either an intervention group or a control group. The intervention group will receive standard care plus a structured mobile application-based perioperative education program including video-assisted pelvic floor muscle training, perioperative education modules, reminders, and follow-up components. The control group will receive routine perioperative care and standard patient education. Data will be collected preoperatively, after urinary catheter removal, and at 1 month and 3 months after surgery. The primary outcomes are urinary incontinence and erectile function, assessed using the International Consultation on Incontinence Questionnaire-Short Form (ICIQ-SF), the International Index of Erectile Function-5 (IIEF-5), and a 24-hour pad assessment. Secondary outcomes include lower urinary tract symptoms and disease-specific quality of life assessed by the International Prostate Symptom Score (IPSS), psychological status assessed by the Depression Anxiety Stress Scale-21 (DASS-21), and system usability assessed by the Turkish version of the Computer System Usability Questionnaire-Short Version (T-CSUQ-SV)

Safety and Tolerability of a Novel Implantable Device for the Treatment of Erectile Dysfunction

The goal of this clinical trial is to assess if a new device is safe to use as a potential treatment for erectile dysfunction following radical prostatectomy. The main questions it aims to answer are: * Is the device safe? * Does the device works well? Are the participants satisfied with the device? Participants will be implanted with the device during the ongoing prostatectomy surgery and will be asked to complete the following tasks during 6 months follow-up: * Come to the hospital for follow-up visits, * Complete questionnaires, * Activate the device every day, * Measure erection hardness. Researchers will compare an implanted group (participants having the device) with a control group (participants not having the device) to see if the device works well.

Platelet Rich Plasma (PRP) as Terapeutical Option in Erectil Disfunction (DE)

Patients are randomized into 2 groups (A and B), subsequently group A is subjected to a cycle of 6 weekly injections of 3 ml of autologous PRP while group B is subjected to 6 weekly injections of 1 ml of caverject (alprostadil) 20 mcg. After 4 (four) weeks the groups will be crossed, so group A will be subjected to 6 weekly injections of 1 ml of caverject (alprostadil) 20 mcg while group B will be subjected to a cycle of 6 weekly injections of 3 ml of autologous PRP.

Pelvic Floor Muscle Training With Aerobic Exercise and Relaxation After Radical Prostatectomy

Post-prostatectomy urinary incontinence (PP-UI) and erectile dysfunction (ED) are common complications after radical prostatectomy, negatively affecting quality of life. Pelvic floor muscle training (PFMT) is widely recommended as the first-line conservative treatment, but recent evidence suggests that multimodal, structured rehabilitation may further improve recovery. This randomized controlled trial will investigate the additional effects of aerobic exercise and relaxation training combined with PFMT in men following nerve-sparing robotic-assisted radical prostatectomy. Forty-eight participants aged 40-65 years, within one year post-surgery, who demonstrate voluntary pelvic floor muscle contraction and sufficient cognitive function (MoCA), will be randomly assigned (1:1) to intervention or control groups. All participants will receive standardized education and a 12-week supervised PFMT program with biofeedback and home-based exercises. The intervention group will additionally perform treadmill-based aerobic exercise three times per week and structured relaxation training once per week. Primary outcomes include urinary symptoms (ICIQ-MLUTS), erectile function (IIEF-15), and prostate cancer-specific quality of life (EPIC). Secondary outcomes include pad test, ICIQ-SF, 6-minute walk test, MoCA, HADS, and adherence. This non-commercial study aims to provide high-quality evidence supporting physiotherapy-based multimodal rehabilitation for improved pelvic health and quality of life in men after prostate cancer surgery.

Regenerative Injection of Stem Cells or Stem Cell-derived Exosomes for Erectile Dysfunction (RISE)

The goal of this prospective observational study is to evaluate whether injections of stem cells derived from the patient's own fat tissue (adipose tissue) can improve erectile function in men aged 30 to 75 who have erectile dysfunction (ED) and have not responded well to standard treatments like PDE-5 inhibitors (e.g., Viagra). The main questions the study aims to answer are: Will the stem cell injections improve erectile function, as measured by the International Index of Erectile Function (IIEF) score? Are there any changes in blood flow to the penis, which will be measured using a Doppler ultrasound? Participants will: Receive injections of their own stem cells (obtained from a biopsy of fat) directly into the penis. Undergo assessments to check erectile function before and after treatment. Have follow-up visits at 3, 6, 9, and 12 months to monitor long-term effects. The study will also look for any possible side effects or complications and evaluate biological markers in the penis that may indicate the effectiveness of the treatment. Participants will be recruited from clinic where they are already receiving care for ED. To take part, they must be in good overall health, with no severe heart disease, uncontrolled diabetes, cancer, or other conditions that could make stem cell therapy unsafe for them.

Pilot Study of a New Nerve Grafting Method During Bladder Cancer Surgery to Help Preserve Erections.

This pilot study will evaluate the safety and 1-year erectile function recovery in 10 patients undergoing a novel Nerve Restoring Radical Cystectomy (NR-RC), which includes a genitofemoral nerve graft. Erectile function will be assessed using IIEF-5, SF-MPQ, and CEEF questionnaires at baseline and at multiple post-operative intervals (4 weeks, 3, 6, 12, and 18 months). Safety will be monitored through peri- and post-operative complications, and additional demographic and clinical data will be collected for analysis.

Effects of Hypopressive Exercises on Urinary Incontinence and Erectile Dysfunction After Radical Prostatectomy

This randomized controlled trial investigates the effects of hypopressive exercises on urinary incontinence and erectile dysfunction in men following radical prostatectomy. Participants will be randomly assigned to one of two groups: a control group receiving home-based pelvic floor muscle exercises and an experimental group receiving both pelvic floor muscle exercises and supervised hypopressive exercises twice per week. The study aims to determine whether the addition of hypopressive techniques, which target coordinated activation of the pelvic floor and abdominal muscles without increasing intra-abdominal pressure, offers greater improvements in urinary and sexual function. Primary outcomes include pelvic floor muscle strength and endurance, while secondary outcomes include urinary incontinence severity, erectile function, and quality of life.

To determine efficacy, safety and tolerabiltiy of topically applied BZ371A in patients that experienced RP, in combination with daily tadalafil compared to placebo.

Low Intensity Shockwave Therapy for Erectile Dysfunction

Low-intensity shockwave therapy (LiSWT) has been deemed "a safe and well-tolerated procedure but its efficacy for the treatment of ED is doubtful and deserves more investigation" by the European Society of Sexual Medicine. In a similar manner, the Sexual Medicine Society of North America and American Urological Association have put forth guideline statements recommending additional investigation of this treatment modality.2 The current clinical armamentarium only treats the symptoms of erectile dysfunction without improving upon the underlying pathophysiology. LiSWT has been used effectively in musculoskeletal disorders and cardiovascular applications. Animal studies have shown improvements in angiogenesis and stem cell recruitment in other systems (cardiac and musculoskeletal) using shockwave therapy. It has been used to treat erectile dysfunction since 2010 and is widely used in Europe and throughout the world. It is gaining widespread acceptance in the United States with a relative paucity of data in regards to its effectiveness. While the majority of studies and meta-analyses show improvements in standardized erectile dysfunction questionnaires (IIEF/SHIM-Sexual Health Inventory in Men, International Index of Erectile Function-5) the durability remains unknown and many have lacked a sham-arm. In addition, many studies have failed to assess a population of men who have highly prevalent erectile dysfunction, those men undergoing prostate cancer treatment. This is a prospective, randomized, single blind, sham-controlled clinical study aimed to evaluate the safety and efficacy of low-intensity shockwave therapy (LiSWT) on symptomatic ED patients in three distinct patient populations. LiSWT has shown the potential to improve baseline erectile function but requires further study, which is the aim of this investigation.

Penile Vibratory Stimulation in the Prevention of Sexual Dysfunction and Urinary Incontinence After Radical Prostatectomy

To investigate if post-operative penile vibration stimulation kan be used to reduce or prevent sexual dysfunction and urinary incontinence after radical prostatectomy. This will be done in a randomized, controlled, non-blinded study. Men that undergo nerve preserving surgery for prostate cancer is allocated into an intervention group and a control group. A total of 100 men will be included for a power of 80%. The intervention group will be instructed to use the "Ferticare 2.0" vibrator for at least five minutes a day with an amplitude of 1 mm and frequency of 90 Hz (these settings were found in a pilot study) for a total of 9 months. Both groups will do the standard pelvic floor training program and both groups will be offered regular phosphodiesterase-5-inhibitor treatment. Before surgery, 3, 6 and 10 months after the patients will have to fill out four different questionnaires regarding sexual and urinary function, including IIEF-EF, EHS, "neglected side effects" and ICIQ-SF. (10 months is due to a wash-out period of 1 month after the intervention). The collected data will be analysed and the primary goal is to see if there is a significant difference in average spontaneous IIEF-EF score in the two groups 10 months after the surgery.
