[Clinical experience with gentamicin in urinary tract infections (author's transl)].

1. Gentamicin (GM) was intramuscularly injected to 1 patient with simple acute cystitis and to 21 patients with complicated chronic urinary tract infections in the doses of 40-160 mg per day for 3-12 days (mean: 5-2 days). 2) The clinical effect was excellent in 6, good in 9, poor in 7, which is classified as excellent in 1 with simple acute cystitis, good in 5 and poor in 5 out of 11 with complicated chronic cystitis, and excellent in 4, good in 4 and poor in 2 out of 10 with complicated chronic pyelonephritis. 3) In complicated urinary tract infections, the effective rate was 61.5% (8/13) in GM 80 mg/day dosage group and 75.0% (6/8) in GM 120 mg/day dosage group. 4) No abnormal change was noted in the kidney, liver and auditory function throughout this clinical study. 5) When GM therapy is conducted in the treatment of complicated urinary tract infections, it is considered that more favorable clinical results could be obtained with dosage of GM 120 mg/day or more. However, in this case a caution has to be paid to the kidney and auditory functions.
