Detaillierte Beschreibung
Benign prostatic hyperplasia (BPH) is a progressive condition causing lower urinary tract symptoms (LUTS) that significantly impairs quality of life in aging men. While medical therapy with alpha-blockers and 5-alpha reductase inhibitors represents first-line management, surgical intervention becomes necessary when symptoms are severe or complications arise.
Anatomical endoscopic enucleation of the prostate has emerged as the size-independent gold standard surgical approach. This prospective randomized controlled trial will be conducted at the Urology Department, Tanta University Hospital (October 2025 - October 2027) following IRB approval (Code: 36265MD479/10/25).
Patients will undergo preoperative evaluation including IPSS, QoL index, IIEF-5, uroflowmetry, transrectal ultrasound, PSA, CBC, coagulation profile, and renal/liver function tests. Intraoperative data will include total operative time, enucleation time, morcellation time, enucleation efficiency (g/min), and estimated blood loss. Postoperative follow-up at 1, 3, and 6 months will assess IPSS, QoL, IIEF-5, Qmax, and post-void residual. Complications will be graded using the Clavien-Dindo classification. Randomization will use the sealed opaque envelope method with 1:1:1 allocation.

|
Anatomical endoscopic enucleation of the prostate performed transurethrally using a Quanta holmium YAG laser at 150 watts with a 550 μm holmium fiber.
Enucleated tissue was removed using a morcellator.
|
|
Aktiver Komparator: Bipolar Enucleation Group
30 patients undergoing Bipolar Transurethral Enucleation of the Prostate using standard bipolar energy
|
Anatomical endoscopic enucleation of the prostate performed transurethrally using standard bipolar electrical energy.

Maßnahmenbeschreibung |
Zeitfenster |
|---|---|---|
|
International Prostate Symptom Score (IPSS)
Zeitfenster: at 1, 3 and 6 months post-surgery
|
Change from baseline in IPSS total score (0-35 scale; higher scores indicate worse urinary symptoms).

|
|
Quality of Life Score (QoL)
Zeitfenster: Baseline and at 1, 3, and 6 months post-surgery
