    Abstract:
    Intravascular absorption of large volumes of solution without electrolytes is a common problem in transurethral resection of the prostate. In the present study we compared two different methods of resection (TURP vs. Vaporization TURP; 20 patients in each group) regarding fluid absorption and loss of blood. In addition, we report on 60 patients who had Vapo-TURP. The operations were performed by different very experienced surgeons. In both groups, spinal anaesthesia and standard regimes of infusion were used. The amount of fluid absorbed was measured by the ethanol method (2 vol.% ethanol; Widmark-formula). Haemoglobin, haematocrit and electrolytes were determined at set times. Ten of the 20 patients in the TURP group showed blood-alcohol levels > 0.1%/1000. In the Vapo-TURP group, only five of 57 patients (three patients with perforation of the prostate capsula were excluded) showed positive levels of blood-alcohol (< 0.05%/1000; fluid absorption < 150 ml). The difference was statistically significant (p = 0.002). Sixty minutes after the beginning of the procedures, the values of haemoglobin and haematocrit were significantly lower in the TURP group (7.68 +/- 0.41 vs. 7.38 +/- 0.64 mmol/l and 0.36 +/- 0.02 vs. 0.34 +/- 0.03). Regarding absorption of fluid and bleeding, Vapo-TURP was superior. From the anaesthesiological point of view, Vapo-TURP should be the method of choice, especially for the elderly.
