简要总结
This prospective randomized study will compare two surgical techniques for treating benign prostatic hyperplasia. Participants will be assigned to either hydrodissection-assisted bipolar prostatic enucleation-enucleoresection with transrectal ultrasound-guided subcapsular injection of diluted norepinephrine and methylene blue or conventional bipolar prostatic enucleation-enucleoresection without injection.
The injected mixture is intended to separate the enlarged prostatic tissue from the surgical capsule and reduce bleeding during surgery. The study will evaluate whether the hydrodissection-assisted technique improves operative conditions, surgical outcomes, postoperative recovery, urinary symptoms, and urinary flow compared with the conventional technique.

研究组 & 干预措施
Hydrodissection-Assisted Bipolar Prostatic Enucleation-Enucleoresection
Participants will undergo transrectal ultrasound-guided subcapsular injection of a diluted norepinephrine-methylene blue mixture to produce hydrodissection between the prostatic adenoma and surgical capsule, followed by bipolar prostatic enucleation-enucleoresection. Standard postoperative bladder irrigation, catheter management, and follow-up will be provided.
干预措施: Hydrodissection-Assisted Bipolar Prostatic Enucleation-Enucleoresection (Procedure)
Conventional Bipolar Prostatic Enucleation-Enucleoresection
Participants will undergo conventional bipolar prostatic enucleation-enucleoresection without subcapsular injection or hydrodissection. Standard postoperative bladder irrigation, catheter management, and follow-up will be provided.
干预措施: Conventional Bipolar Prostatic Enucleation-Enucleoresection (Procedure)
结局指标
主要结局
Intraoperative Blood Loss
时间窗: Intraoperatively
The estimated volume of blood lost during the operative procedure will be recorded in milliliters and compared between the hydrodissection-assisted and conventional groups.
次要结局
- Operative Time(Intraoperatively)
- Enucleated Prostatic Tissue Weight(Immediately after tissue retrieval, intraoperatively)
- Length of Hospital Stay(From completion of surgery until hospital discharge, assessed up to 7 days)
- Urethral Catheterization Duration(From completion of surgery until catheter removal, assessed up to 7 days)
- Change in Maximum Urinary Flow Rate(At baseline and at 1, 3, and 6 months after surgery)
- Change in Post-Void Residual Urine Volume(At baseline and at 1, 3, and 6 months after surgery)
- Change in International Prostate Symptom Score(At baseline and at 1, 3, and 6 months after surgery)
- Incidence of Postoperative Complications(At 1, 3, and 6 months after surgery)
- Incidence of Intraoperative Complications(Intraoperatively)
