It is not unusual to encounter difficulty in passing the cystoscope into the bladder, because of stricture and false passage with urethral bleeding from attempts at passage. Urethroscopy under direct vision may facilitate passage through the stricture provided

the bladder is not distended, and there is no urethral bleeding. Often vision is obscured by bleeding in the urethra. Continuous irrigation of the urethra can be achieved by passing a ureteral catheter to obtain drainage, using the principle of the continuous

flow resectoscope (Fig. 1). Opening the valve opposite the inflow valve on the cystoscope will not achieve this. However, a large ureteral catheter (7 or 8 F) placed near the objective lens through the usual catheterization opening on the cystoscope, and allowed to drain freely into the pan of the cystoscopy table will permit clearer vision. If the catheter becomes plugged, it can be irrigated easily. 560 First Avenue New York, New York 10016
