Abstract
Increased urinary excretion of beta 2-microglobulin and certain enzymes, for example leucine aminopeptidase (LAP) and N-acetyl-beta-D-glucosaminidase (NAG), produces sensitive markers of damage to renal tubular cells. These markers were monitored in patients undergoing obstetric and gynaecological surgery who received cefotaxime for 5 days. Slight increased activity in NAG and beta 2-microglobulin was observed in some patients 3 to 5 days after surgery. However, no changes of significance were found in levels of urinary LAP and NAG. During cefotaxime treatment, urinary beta 2-microglobulin in the group of abdominal hysterectomy increased slightly. In most cases renal side effects are negligible and cannot be detected by these tests. These results indicate that administration of cefotaxime in obstetric and gynaecological surgery does not produce cumulative renal tubular toxicity.
