Transurethral Plasmakinetic Enucleation of Prostate Versus Transurethral Resection of Prostate

Not Applicable

• Conditions: Benign Prostatic Hyperplasia

• Registration Number: NCT03157726
• Lead Sponsor: Zhujiang Hospital

Brief Summary

The study is a multicentric randomized control trial with 4-year follow-up comparing perioperative and postoperative outcomes for transurethral plasmakinetic enucleation of prostate(TUKEP) and transurethral resection of prostate(TURP). The investigators recruit patient with benign prostatic hyperplasia(BPH) as the object of study. TURP is set as control group . Meanwhile TUKEP is set as test group. Six affiliated hospitals will participate in this study. Through analyzing the perioperative and postoperative data between TUKEP group and TURP group, The investigators purpose demonstrating superiority of safety, efficacy and economic benefit in TUKEP group.

Detailed Description

Benign prostatic hyperplasia (BPH) is the most common disease of middle aged and elderly people which cause urinary tract symptoms (LUTS). transurethral resection of prostate(TURP) , began to replace the traditional open surgery in 1930s, still is as the "gold standard" operation for surgical treatment of BPH. However, compared with the traditional open operation, TURP has the following flaws:(1), due to the incomplete resection , maximum flow rate(Qmax) after TURP is lower than Qmax after open surgery. (2), there are serious complications, such as water intoxication and hemorrhage. (3) TURP has limitation to large prostate.

Transurethral plasmakinetic enucleation of prostate(TUKEP), an operation mode devised by Liu Chunxiao Team in southern medical university urology department, have offset the advantage of TURP. The theory of the operation is using transurethral resectoscope instead of the finger in the open operation, to find the surgical capsule of prostate and to peel the hyperplastic prostate gland visually in a antidromic way. One the one hand, TUKEP effectively solve the situation that It should repeatedly cut and stop bleeding and difficultly find the surgical capsule in TURP, which obviously reduce the rate of bleeding, prostatic capsula perforation, transurethral resection syndrome(TURS) and External sphincter injury. On the other hand, TUKEP is the minimally invasive surgery. It also achieves the effect of open surgery resolving the residual gland and reoperation post TURP.

The investigators plan to setup a a multicentric randomized control trial with 4-year follow-up comparing perioperative and postoperative outcomes for TUKEP and TURP. Through analyzing the perioperative and postoperative data between TUKEP group and TURP group, The purpose demonstrating superiority of safety, efficacy and economic benefit in TUKEP group.
