Bacteriuria after Operation in the Department of Urology

Abstract

To clarify the actual condition of bacteruria after operation, statistical analysis was carried out on bacteriuria in 333 inpatients in the department of urology of Yamaguchi University Hospital. The number of the strains isolated from the urine of all the patients during the 4 years from 1975 showed a decreasing tendency, but Serratia and Pseudomonas aeruginosa continued to be observed in many patients. In benign diseases, the postoperative bacteriuria was apparently correlated, respectively, to the period of indwelling catheterization, presence of bacteriuria before operation, age and the combined treatment of β-lactam antibiotics with aminoglycosides. In malignant cases, the correlation was observed only to the 2 former factors above mentioned. The correlation between bacteriuria and the operation procedure was not confirmed from the sample size in this analysis.
