Single-dose treatment with netilmicin for different clinical forms of urinary tract infections.

A group of 44 patients with various clinical forms of urinary tract infections received a single dose of 300 mg netilmicin i.m. The treatment was efficacious in all patients with infections which were negative in the antibody-coated bacteria test and not complicated by anatomic and/or functional abnormalities of the kidneys and urinary tract. After three weeks the recurrence rate was only 19%. Single-dose treatment also proved very effective against urinary tract infections in renal transplant patients whose infection is almost always located in the lower urinary tract. In contrast, the short-term results of treatment were much poorer in complicated infections and particularly in urinary tract infections which were positive in the anti-body-coated bacteria test; here, the recurrence rate was 67%.
