Increasing urethral occlusion pressures were created with an artificial sphincter in bladder-urethra specimens of adult female pigs. Antegrade urethral perfusion pressures, at 19.5 ml./min. through a flexible F8 urethral catheter with an F12 outflow sleeve of tube-foil, closely approximated the associated intravesical pressures at which leakage from the noncatheterized urethra starts. With this new technique, leakage pressure and thus urethral competence can be measured accurately and continuously, almost independently from bladder pressure and pelvic floor movement.
在成年雌性猪的膀胱尿道标本中，使用人工括约肌增加尿道闭塞压力。通过一根带有箔管F12流出套管的柔性F8尿道导管，以19.5毫升/分钟的速度进行顺行尿道灌注压力测量，该压力与非导尿管尿道开始漏尿时的膀胱内压力密切接近。采用这种新技术，可以几乎独立于膀胱压力和盆底运动，准确且连续地测量漏尿压力，从而测量尿道功能。
