Anterior Bridge-Preserving Versus Conventional Early Apical Release in Bipolar Enucleation of the Prostate

Bipolar enucleation of the prostate is an effective operation for men with urinary obstruction caused by a benign enlarged prostate. Some men leak urine for a period after the operation. Early apical release is a surgical step that frees the tip (apex) of the prostate at the start of the operation to reduce stretch on the urinary sphincter. The conventional technique cuts all the way around the apex, including the front (anterior) tissue next to the sphincter. This randomized trial compares a modified technique, Anterior Bridge-Preserving Semicircular Early Apical Release (ABP-S-EAR), with conventional early apical release. ABP-S-EAR leaves the front tissue bridge between the 11 and 1 o'clock positions intact. Men aged 45 to 80 years scheduled for bipolar enucleation at Benha University Hospital, Egypt, will be randomly assigned to one technique. The main question is whether ABP-S-EAR improves urinary continence 1 month after surgery. The trial also compares patient-reported leakage, operative time, bleeding, catheter time, hospital stay, urinary symptoms, urine flow, and complications over 12 months.

Anterior Bridge-Preserving Versus Conventional Early Apical Release During Holmium Laser Enucleation of the Prostate

Holmium laser enucleation of the prostate (HoLEP) is an effective operation for men with urinary obstruction caused by a benign enlarged prostate. Some men leak urine for a period after the operation. Early apical release is a surgical step that frees the tip (apex) of the prostate at the start of the operation to reduce stretch on the urinary sphincter. The conventional technique cuts all the way around the apex, including the front (anterior) tissue next to the sphincter. This randomized trial compares a modified technique, Anterior Bridge-Preserving Semicircular Early Apical Release (ABP-S-EAR), with conventional early apical release during HoLEP. ABP-S-EAR leaves the front tissue bridge between the 11 and 1 o'clock positions intact. Men aged 45 to 80 years scheduled for HoLEP at Benha University Hospital, Egypt, will be randomly assigned to one technique. The main question is whether ABP-S-EAR improves urinary continence 1 month after surgery. The trial also compares continence at 3, 6, and 12 months, operative time, bleeding, catheter time, hospital stay, urinary symptoms, urine flow, and complications.

Selective Median Lobe Surgery Outcomes Study

This prospective multicenter observational cohort study will evaluate clinical outcomes after selective median lobe transurethral surgery for benign prostatic obstruction. Eligible men with lower urinary tract symptoms or urinary retention who are scheduled for selective median lobe-only TURP, HoLEP, or anatomical endoscopic enucleation as part of routine clinical care will be enrolled and followed after surgery. The study will collect preoperative clinical data, symptom scores, uroflowmetry, postvoid residual volume, prostate volume, intravesical prostatic protrusion measurements, cystoscopic anatomical findings, intraoperative variables, and postoperative outcomes. The primary outcome is composite clinical failure at 12 months. The main aim is to identify practical preoperative urology-based anatomical and functional predictors of clinical failure after selective median lobe surgery and to develop an exploratory prediction model that may help improve patient selection in future practice.

Irreversible Electroporation (IRE) for the Treatment of Lower Urinary Tract Symptoms (LUTS) in Men With Benign Prostatic Hyperplasia (BPH)

This study will evaluate the safety and effectiveness of using Irreversible Electroporation (IRE) for the treatment of symptomatic benign prostatic hyperplasia (BPH).
