前列腺增生症所致尿潴留是泌尿外科的常见急症,患者多需急诊导尿处理,但部分病人因前列腺重度肥大,导尿不易成功,往往被迫行手术造瘘治疗。为此作者设计加工了一种金属鞘管导尿置入器,经临床22例尿潴留患者应用均获成功。现将材料与结构及使用方法介绍如下。一、材料与结构该装置由金属外鞘管及内芯二部分组成:(1)外鞘管采用20F、22F不锈钢管制做成两种不同规格的L形外鞘,管壁厚0.5mm,长260mm,管鞘L形顶端外缘打磨成斜面,尾端有
Urinary retention caused by benign prostatic hyperplasia is a common emergency urology, patients need emergency catheterization, but some patients due to severe prostatic hyperplasia, catheterization is not easy to succeed, often forced to perform surgical fistulation. To this end, the author designed and fabricated a metal sheath catheterization device, which was successfully applied in 22 patients with urinary retention. Now the material and structure and method of use are described below. First, the material and structure The device consists of a metal sheath and the inner core of two parts: (1) outer sheath made of 20F, 22F stainless steel tube made of two different specifications of L-shaped sheath, tube wall thickness 0.5mm, length 260mm, tube sheath L-shaped top edge polished into a bevel, the tail has
