glycine (analysed by anion-exchange chromatography).
RESULTSComplete data on 120 men were assessed; 75% of the men absorbed irrigation fluid, with glycine levels above the normal range. The sodium levels tended to decrease with increasing glycine levels (Spearman's rank correlation coefficient, − 0.57; 120 men) and five men (4%) developed clinical features of the TUR syndrome. There was a weak correlation between breath-ethanol levels and serum glycine levels (Spearman's rank correlation coefficient, 0.54). The experience of the surgeon, the weight of the resected chips, and the operative duration were not significantly predictive of irrigation fluid absorption.
CONCLUSIONSA rising breath-ethanol level indicates irrigation fluid absorption. However, irrigating fluid absorption is unpredictable, supporting the case for alternative, potentially safer irrigants.
