Online Adaptive Stereotactic Body Radiotherapy for Localized Prostate Cancer (X-SMILE)

The aim of this phase II international multicenter study is to evaluate the safety, feasibility, and efficacy of CT or MRI-adaptive SBRT, delivered in five weekly fractions, in patients with newly diagnosed localized prostate cancer who have lower urinary tract symptoms and/or prostatic hyperplasia.

5-Alpha Reductase 2 as a Marker of Resistance to 5ARI Therapy

The study is being conducted to learn why some patients with Benign Prostatic Hyperplasia (BPH) do not respond to a commonly used treatment drug, Finasteride. The hope is to find ways to predict which patients will not respond to Finasteride so that, in the future, these patients can be identified prior to offering this treatment and they can be offered alternative treatment strategies in its place. The aim is to see if noninvasive techniques such as MRI can detect inflammation of the prostate to assist with early detection of those who will and who will not respond to Finasteride.

Comparison Between Bipolar Transurethral Resection of the Prostate and Moses Assisted Holmium Laser Enucleation of the Prostate

Introduction: Multiple studies have demonstrated the superiority of HoLEP in aspects such as transfusión rates or postoperative stay. On the other hand, no differences have been observed in terms of functional outcomes between both techniques, and surgical times reported in different studies tend to be longer for HoLEP. These results likely contribute to TURP, especially with bipolar energy (Bi-TURP), continuing to be considered by many the gold standard for surgical treatment of BPH. Sofware and hardware upgrades to the Lumenis Pulse 120H. system in 2017, delivered MOSES 2.0, a single-use laser fibre used to perform MOSES augmented HoLEP (MoLEP). MoLEP has shown to be superior in intraoperative outcomes when compared to traditional HoLEP. The availability of new morcellators might also decrease surgical time for HoLEP. This changing landscape for BPH endoscopic surgery deserves a re-evaluation of the differences between Bi-TURP and MoLEP. Primary Objective: To compare the hospital stay of patients of patients undergoing MoLEP with those undergoing Bi-TURP. Secondary objectives: * To compare the surgical time of MoLEP with that of Bi-TURP. * To compare the bladder catheterization time aCer MoLEP with that of Bi-TURP. * To compare the postoperative complication rate patients undergoing MoLEP with those undergoing Bi-TURP. * To compare functional results of patients undergoing MoLEP with those undergoing Bi-TURP. This study is a prospective multicentric randomized and controlled trial. The study compares two types of BPH surgery without changing standard medical practice. The study will include patients who are candidates according to standard medical practice for BPH surgery. Patients will be randomized to one of two groups of treatment. * The MoLEP group will receive surgical treatment with MoLEP. * The Bi-TURP group will receive surgical treatment with Bi-TURP. Surgical technique and postoperative care will follow standard clinical practice at each participating centre.

BETTY: BEnign Prostatic Hyperplasia Transperineal Targeted Microwave therapY

This is a pilot study on applying 3D-Ultrasound-Guided Transperineal Microwave needle ablation for men with symptomatic benign prostatic hyperplasia (BPH).

Management of Dysuria and Irritative Symptoms After HoLEP: a Prospective Study Evaluating the Efficacy of Alpha-Blocker Therapy

Holmium Laser Enucleation of the Prostate (HoLEP) is an increasingly popular endoscopic minimally invasive surgical technique for the treatment of benign prostatic hyperplasia (BPH). In the literature, the long-term efficacy and low complication rates of HoLEP have been highlighted in many studies. However, in the early postoperative period, particularly within the first three months, irritative symptoms are reported in 17-35% of cases (1-2). The pathophysiology of postoperative irritative symptoms is not yet fully understood, but it has been suggested that these symptoms may be associated with urethral trauma, the mucosal healing process, and detrusor overactivity. These symptoms can significantly impact quality of life, reducing patient satisfaction. In particular, dysuria is a frequently encountered symptom after HoLEP, with considerable individual variability in its severity and duration. The effectiveness of alpha-blockers in alleviating postoperative dysuria and irritative symptoms remains a topic of debate in the literature. Although prostate tissue is surgically removed, alpha-blockers may improve urinary flow and relieve symptoms associated with bladder outlet obstruction by reducing urethral smooth muscle tone (3). Studies on the use of alpha-blockers following transurethral resection of the prostate (TURP) have shown limited postoperative benefits (4). However, to the best of our knowledge, no study has specifically evaluated their use following HoLEP, an enucleation-based technique. Therefore, further studies are needed to assess the role of alpha-blockers in managing dysuria after HoLEP. The aim of this study is to evaluate the effectiveness of alpha-blocker therapy in managing dysuria and other irritative symptoms following HoLEP. Additionally, the study seeks to determine the impact of this treatment on quality of life and patient satisfaction.

Prostate Single Port & Laser Enucleation Comparison Trial

Surgical treatments for benign prostatic hyperplasia (BPH) are necessary when non-procedural approaches fail to alleviate lower urinary tract symptoms (LUTS) or bladder outlet obstruction (BOO). Open simple prostatectomy and laser enucleation are recommended for prostatic adenoma size greater than 80 ml. Minimally invasive approaches, such as robotic-assisted simple prostatectomy, have gained popularity due to their comparable outcomes with lower morbidity. The introduction of the da Vinci single-port (SP) robotic platform offers potential advantages, but its outcomes have not been thoroughly investigated. This randomized controlled trial aims to compare the outcomes of SP simple prostatectomy performed using the da Vinci robotic platform versus thulium laser enucleation of the prostate for the treatment of BPH and BOO.
