The three-circle single J catheter: a more stable urethral catheter for pressure flow studies.
We describe a single J urethral catheter which has been specially designed to facilitate stabilization during voiding in pressure flow studies. It has a tip with three circles, which prevents the catheter from slipping out even when there is a sudden increase in intra-abdominal pressure.
