[Improvement of endoscopic resection procedures in relation to the volume of prostatic adenoma]

First choice therapy of obstructive prostatic hyperplasia is still represented by endoscopic transurethral resection of the prostate, despite new techniques for tissue ablation have being proposed. The issue aims to answer to the questions arising about indications of this procedure, and introduces to the knowledge of physical laws which regulate irrigation during and after operation and to the different techniques of irrigating flow derivation whose application reduced morbidity depending on tissue volume and "resection time". Moreover, the new technique of continuous resection with simultaneous suprapubic evacuation of tissue chips (Turbo-TUR) will be illustrated in details, as it permitted to extend indications and advantages of endoscopic surgery to bulky adenomas, electively submitted to open surgery up to now.
