In 26 patients with different clinical forms of infections of the urinary pathways a 300 mg single dose of netilmicin was administered by the i.m. route and the bacteriological urinary finding was checked for as long as 10 weeks after administration of netilmicin. During this period the urine was bacteriologically negative in 42% of the subjects. In 8 subjects with relapses of the infection a second dose of 300 mg netilmicin was administered and the urine was bacteriologically negative for 10 weeks in four of the patients. On the whole it proved possible to eliminate the urinary infection for 42-112 days in 17 subjects (65%), even in so-called complicated infections. It may be stated that single dose treatment with netilmicin used once or repeatedly leads to prolonged elimination of the infection without affecting the sensitivity of the organisms, without side-effects and with a substantial reduction of the cost of treatment.
