[Urinary tract infection associated with benign prostatic hypertrophy and related diseases and transurethral surgery]

Three hundred and fifty five patients were treated with transurethral resection of the prostate for the relief of partial urinary obstruction. Of these, 188 had suffered from bacteriuria before surgery and the remaining 167 had been free of urinary infection before surgery. Urinary infection was caused by urethral instrumentation including indwelling catheter for various periods of time. A significant correlation between volume of residual urine and preoperative infection was demonstrated. No correlation between preoperative infection and postoperative voiding efficiency was however noticed though significant improvement in voiding was demonstrated by postoperative uroflowmetry.
