[Study of the long-term administration of ofloxacin to the patients following transurethral resection of the prostate]

Abstract

The present study was undertaken to evaluate the clinical efficacy of long-term administration of ofloxacin (OFLX) to the patients following transurethral resection of the prostate. The patients were randomly divided into two groups: A and B. All the patients were administered flomoxef (FMOX) intravenously for 3 days following transurethral resection of the prostate (TUR-P). In group A, 100 mg of OFLX twice daily was thereafter administered for 4 to 15 weeks to 22 patients until they showed an improvement in pyuria. In group B, which served as a control, neither OFLX nor any other antibiotics were administered to 26 patients until they showed an improvement in pyuria. No patients complained of urination trouble due to infection. At the same time, cultures of bacillus in the urine were also examined 4 days, 7 days and 2 weeks after TUR-P with these two groups. The mean days necessary for the improvement of pyuria were 64.9 +/- 20.5 in group A, 66.3 +/- 18.4 in group B. At 2 weeks after TUR-P, bacillus in the urine were negative in 19/22 patients in group A, and 14/26 in group B. Chi-square test showed significance for these two groups. Accordingly, OFLX was useful for bacillus in the urine, but OFLX was not so useful for shortening the continuance of pyuria of post TUR-P. No patients complained of nausea or any other complications during the study.
