The effectiveness of Sulfobenzylpenicillin in the treatment of urinary
tract infection was evaluated in the Department of Urology, Seoul National University Hospital during the period from May to November, 1973. Our clinical study was performed on the 28 patients who visited the outpatients clinic and admitted to the ward. These patients were studied by bacterioscopy with Gram`s method of staining. and culture in blood agar plate and chocolate agar plate In this studies. the causative organisms were divided into 8 groups; E. coli (5), coagulase positive staphylococcus (5), pseudomonas (2), Corynebacterium spp. (1), a-hemolytic etreptococcus (2), N. Gonorrheae (10), Proteus (2) and KIebsiella (1). The dosage schedule was 1 gm. of Sulfobenzylpenicillin at intervals of 12 hours for consecutive 5 days in gonococcal urethritis and nongonococcal urethritis. But in upper urinary tract infections and post-operative infections, it lasted for 7 to 10 days or more. And following results were obtained. Effectiveness on Urological diseases 1) Gonococcal urethritis; Satisfactory clinical results were obtained with Sulfobenzylpenicillin for five days. Results were excellent in 5 cases, good in 4 cases and negative effect in 1 case. 2) Non-gonococcal urethritis; In this group, the therapeutic results were favorable in 90% of all cases. (excellent-4, good-5, fail-l) 3) Urethral stricture and fistula (2 cases); AII cases were responded to the Sulbenicillin. 4) Cystitis including Prostatism; Two of three cases were caused by E. coli and they had a good response to sulbenicillin. 5) Two cases of pyelonephritis and two cases of postoperative infections were studied with sulbenicillin and more than 60% of cases were effective with sulbenicillin. Side effects were not remarkable but in a few cases who received intramuscular injection, pain on the injection site was noticed.In summary, this new semi-synthetic penicillin is considered to be a useful chemotherapeutic weapon against a variety of infection in the urological field including those due to Gram negative bacilli such as pseudomonas and proteus sp.
