Netilmicin in urinary tract infections.

: 30 urological patients with normal renal function were treated with netilmicin because of urinary tract infections, mostly recurrent and due to predisposing factors. the drug was given in doses of 4 mg/kg/day for 4-9 days. All but 5 patients had resolution of their signs and symptoms, and the bacteria were eliminated in 23 patients, with recurrence in 8 and reinfection in 3. The bacteria persisted in 1 patient and the results were indeterminate in 6 patients. No signs of hematopoietic, renal and hepatic toxicity occurred, and vestibular and auditory functions were undisturbed. Regular assays of serum drug concentrations revealed no signs of accumulation. Netilmicin given in doses of 4 mg/kg/day is an efficient antibiotic with low toxicity in the treatment of urinary tract infections.
