OBJECTIVES

To describe the initial experience of a newly designed temporary urethral catheter, ContiCath, as an aid in the management of postoperative or temporary outflow obstruction. In patients with normal detrusor and sphincter function, this catheter allows volitional voiding while maintaining an open prostatic urethra.

METHODS

In a pilot study, 64 nonconsecutive patients with postoperative or temporary urinary retention, at eight clinical trial sites, were enrolled for the placement of this temporary catheter. Three patients did not have the catheter placed because of placement failure because of either a large median lobe or a urethral stricture. The remaining 61 patients were divided into three groups: those with non-neuropathic causes of retention and retention for 1 week or less (37 patients), those with non-neuropathic causes of retention and retention for longer than 1 week (19 patients), and those with neuropathic causes of retention and retention for longer than 1 week (5 patients). The ContiCath is placed in the office setting, in the same fashion as a Foley catheter. A blue prolene tether extends from the bulbar urethra to the meatus to assist in the removal of the device. Patients were then reassessed at 3 hours, and at 7, 14, 21, and 28 days, at which point the device was removed.

RESULTS

In patients with a neuropathic cause for their retention (5 patients) and those with non-neuropathic causes of retention and retention for longer than 1 week (19 patients), only 3 patients were able to void after the catheter was placed. Of the 37 patients with a non-neuropathic cause and retention 1 week or less, controlled voiding was seen in 33 patients (89%). Controlled voiding was defined as the patient's volitional ability to initiate and stop his urinary stream. There were no complications with catheter placement; however, 8 patients (24.2%) had minor adverse experiences of frequency/urgency (n = 3), incontinence (n = 3), migration of the catheter (n = 1), and pain (n = 1).

CONCLUSIONS

ContiCath offers an alternative to an indwelling Foley catheter in men with temporary bladder outlet obstruction and urinary retention.

目的

描述一种新设计的临时尿道导管ContiCath在处理术后或临时流出道梗阻方面的初步经验。对于逼尿肌和括约肌功能正常的患者，该导管可在保持前列腺尿道开放的同时实现自主排尿。

方法

在一项前瞻性研究中，来自八个临床试验地点的64例非连续性术后或临时尿潴留患者入选接受该临时导管置入。3例患者因中叶较大或尿道狭窄导致置管失败而未置入导管。其余61例患者分为三组：非神经性原因导致尿潴留且尿潴留时间为1周或更短的患者（37例），非神经性原因导致尿潴留且尿潴留时间超过1周的患者（19例），以及神经性原因导致尿潴留且尿潴留时间超过1周的患者（5例）。ContiCath在门诊环境中置入，方式与Foley导管相同。一条蓝色的聚丙烯系带从球部尿道延伸至尿道口，以协助取出该装置。然后在3小时、7天、14天、21天和28天时对患者进行重新评估，此时取出该装置。

结果

在因神经性原因导致尿潴留的患者（5例）以及因非神经性原因导致尿潴留且尿潴留时间超过1周的患者（19例）中，仅3例患者在导管置入后能够排尿。在37例非神经性原因导致尿潴留且尿潴留时间为1周或更短的患者中，33例（89%）实现了可控排尿。可控排尿定义为患者自主启动和停止尿流的能力。导管置入无并发症；然而，8例患者（24.2%）出现了轻微不良事件，包括尿频/尿急（3例）、尿失禁（3例）、导管移位（1例）和疼痛（1例）。
