[Treatment of urinary tract infections caused by unknown bacteria (author's transl)].

The treatment of acute febrile urinary tract infections in urological patients has to start in most cases without knowledge of bacteria and their sensitivity. The results of 2,000 antibiograms and clinical observations showed good efficiency in initial therapy if combined treatment with gentamycin and cephalothin was used. Using recommeneded doses in permanent control of serum creatinine and blood-urea nitrogen, no decrease of renal function was observed in 131 patients treated with this combined therapy.
