A Prospective Comparative Study Evaluating the Safety and Efficacy of Transurethral Thulium Fiber Laser, Holmium Laser and Bipolar Enucleation of Large Sized Prostate
연구 개요
상태
상세 설명
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.
