[Prophylactic antibiotic therapy in endoscopic resection of the prostate. Randomized study of 47 cases (author's...

The authors investigated the effect of giving a single injection of the antibiotic gentamycin one hour before endoscopic resection of the prostate, by random case selection in a group of 47 cases. The untreated and the treated cases were considered quite comparable. The presence of bacteriurea greater than 10(5) per ml during the first 15 postoperative days was significantly greater in the untreated group than in the preoperatively treated group. The results showed 44% for the untreated group and 14% for the treated group. After 15 days the results were identical for the two groups.
