Anterior Bridge-Preserving Versus Conventional Early Apical Release in Bipolar Enucleation of the Prostate
Sponsor: Benha University
Summary
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 Semicircular Early Apical Release (ABP-S-EAR)
Bipolar Collins knife, 26 Fr continuous-flow resectoscope, 120 W cut, 80 W coagulation. Right incision from 6 o'clock proximal to the verumontanum along the lateral mucosal groove to 11 o'clock; left incision from 6 to 1 o'clock. The 11 to 1 o'clock anterior bridge is preserved. Paired longitudinal incisions from the bladder neck at 11 and 1 o'clock join the apical incisions. Retrograde lobe mobilization in the capsular plane leaves the bridge undisturbed, then intravesical morcellation. Conversion to conventional EAR is allowed if a safe capsular plane cannot be developed.
Conventional Early Apical Release (EAR)
Same bipolar Collins knife, resectoscope, energy settings, and irrigation as the experimental arm. Continuous circumferential mucosal incision along the proximal border of the external sphincter, through 12 o'clock, completely dividing the anterior mucosal bridge. Retrograde enucleation by the standard institutional bipolar technique, then intravesical morcellation.
