Blood Loss in Prostatic Resection after Relief of Acute Retention of Urine by Prolonged Catheter Drainage

Blood loss in transurethral resection of the prostate was measured in 31 patients and a comparison made between 12 who had required prolonged preoperative bladder drainage by indwelling urethral catheter and 19 who had not been catheterised. There was no difference in blood loss per gram weight of prostatic tissue resected per minute operating time between the two groups.
