title: Transurethral vaporisation of the prostate and irrigating fluid absorption.
abstract: Transurethral vaporisation of the prostate gland (TUVP) is an emerging surgical alternative to conventional electroresection (TURP). This study examined vesical pressure and fluid absorption during TUVP in 35 patients with benign prostatic hypertrophy. The irrigating fluid was a solution of glycine 1.5% and ethanol 1%. Intraoperative intravesical pressure was monitored continuously and absorption of irrigating fluid was detected by ethanol analysis in expired breath. The incidence of absorption during TUVP was 34%. Intravesical pressures were higher amongst patients who went on to absorb than amongst patients who did not. Combining data from the current study and from 35 patients in our previous investigation into TURP (Gray et al.: Anaesthesia 2001; 56: 461-4), urological trainees operated at higher mean pressure and for longer than their consultant colleagues and their resections were significantly more likely to result in absorption. The incidence of irrigating fluid absorption during trainees' operations appeared to be less using TUVP than using conventional TURP.
