经尿道前列腺切除术英文为Transurethral resection of the prostate，简称TURP。这是一种泌尿外科的手术，用来治疗良性前列腺增生症，而前列腺也称为摄护腺，是男性特有的器官。顾名思义，医师使用器械从尿道进入，以电刀将前列腺组织一片一片削下来，使尿道内径变大，改善排尿功能。自1960年代问世以来，被许多泌尿科医师认为是治疗良性前列腺增生症最有效的方法。

Transurethral resection of the prostate (commonly known as a TURP, plural TURPs, and rarely as a transurethral prostatic resection, TUPR) is a urological operation. It is used to treat benign prostatic hyperplasia (BPH). As the name indicates, it is performed by visualising the prostate through the urethra and removing tissue by electrocautery or sharp dissection. This is considered the most effective treatment for BPH. This procedure is done with spinal or general anaesthetic. A triple lumen catheter is inserted through the urethra to irrigate and drain the bladder after the surgical procedure is complete. Outcome is considered excellent for 80-90% of BPH patients.
