Urinary tract infections in patients undergoing transurethral prostatectomy

The incidence of urinary tract infections was determined in 1,660 patients undergoing transurethral prostatectomy. Preoperative infection was found in 25% of all patients and in 35% of the 276 patients aged 80 years or over. Of the 1,251 patients without a preoperative infection, 17% had postoperative infections. The incidence of new postoperative infection was significantly related to the duration of surgery and the weight of the resected prostate. The incidence of infection was higher in summer than in winter months.
