Abstract
Transurethral resection of the prostate was performed using intermittent-flow bladder irrigation (n = 50), or by continuous-flow irrigation, using a suprapubic trocar (n=50). The irrigant solution contained 1.5% glycine + 1 % ethanol and fluid absorption was measured from the ethanol content of the expired breath, Fluid absorption was significantly lower in patients receiving continuousflow irrigation (p<0.007) although major absorption occurred in one of these patients. The immediate detection of absorption with the ethanol method allowed us to stop one of the operations performed with intermittent bladder irrigation, at which 2 1 of fluid had been absorbed in 20 min, With correction for the amount of removed prostatic tissue, there were no differences in operation time or blood loss between the two types of irrigation.
