Comparison between continuous flow and intermittent flow transurethral resection in 40 patients presenting with acute retention.

Forty patients admitted with acute retention of urine were treated by transurethral resection of the prostate by either the continuous or intermittent flow resectoscope. No significant differences or trends were demonstrated between the 2 techniques in respect of speed of resection, blood loss and amount of glycine absorbed. There was a marked degree of haemodilution during surgery in some patients.
