The effect of double Malecot type polyurethane intraurethral catheter (IUC) was examined in 17 benign prostatic hypertrophy patients who were unfit for operation and suffered from urinary retention. Patients were aged 68 to 90 (mean 80.5) years old and the causes of IUC insertion were cardiac, cerebrovascular, respiratory and gastrointestinal diseases, diabetes mellitus and aging. IUC was selected among three types (55, 60, 65 mm) according to the length of prostatic urethra. Insertion of IUC was carried out easily under fluoroscopic guidance without endoscopy. All patients could void by themselves just after insertion of IUC and the longest indwelling period was 10 months. The length of IUC need not be longer than that of prostatic urethra and patients with normal or hypertonic bladder could void better than those with atonic bladder. Urinary tract infection did not get worse in any patients with indwelling IUC. Double Malecot type polyurethane IUC is a safe and an effective alternative method in place of urethral balloon catheter for inoperable prostatic hypertrophy patients in urinary retention.
对17例因良性前列腺增生导致尿潴留且不宜手术的患者，研究了双猪尾型聚氨酯尿道内导管（IUC）的效果。患者年龄在68至90岁（平均80.5岁）之间，插入IUC的原因包括心脏、脑血管、呼吸和胃肠道疾病、糖尿病以及衰老。根据前列腺尿道长度，从三种型号（55、60、65毫米）中选择IUC。在荧光镜引导下，无需内镜即可轻松插入IUC。所有患者在插入IUC后即可自行排尿，最长留置时间为10个月。IUC的长度不必长于前列腺尿道，膀胱正常或张力过高的患者比膀胱无张力的患者排尿情况更好。留置IUC的患者中，尿路感染均未加重。对于因前列腺增生导致尿潴留且无法手术的患者，双猪尾型聚氨酯IUC是一种安全有效的替代尿道球囊导管的方法。
