Incidence of urethral stricture after transurethral resection of prostate. Effects of urinary infection, urethral flora, and catheter material and size

Abstract

Urethral stricture is the most common complication of transurethral resection of prostate, occurring in up to 29 per cent of cases. A prospective trial was initiated to ascertain if the presence of positive urine and urethral bacterial cultures made any significant difference in urethral stricture incidence. One hundred patients were entered in the trial, 50 receiving latex catheters and 50 receiving Teflon catheters. There was no significant difference between the two groups in incidence of urethral stricture, and there was no correlation between positive urine and urethral bacterial cultures and stricture formation. It is suggested, therefore, tha urethral catheter material and size and the presence of organisms in the urine and in the urethra do not contribute significantly to the formation of urethral stricture following transurethral resection of the prostate.
