Greenlight laser vaporization versus transurethral resection of the prostate for the treatment of benign prostatic obstruction: evidence from randomized controlled studies

Transurethral resection of the prostate (TURP) is almost always regarded as the standard in the surgical treatment for benign prostatic obstruction (BPO). However, TURP is not uncommonly associated with perioperative morbidities, which are directly related to prostate volume and surgically high-risk patients with associated comorbidity, including pacemakers, anticoagulant and platelet antiaggregant medications. The time-dependent absorption of electrolyte-free irrigating fluid leading to hyponatremia, usually limit the time to perform a safe monopolar TURP especially in large adenomas.
