We describe the use of a new urethral stent implanted into 12 patients with prostatic outflow obstruction. All were in a high risk group for surgery and 11 were treated successfully, with a follow-up of 1 to 11 months (median 9). The majority of patients were satisfied with the procedure, which provided a quick, safe and effective alternative to conventional surgical treatment. The stent, woven from fine stainless steel in the form of a tubular mesh, was inserted via a delivery device using combined ultrasound and endoscopic control under local anaesthesia. The procedure was well tolerated, the stent becoming covered with epithelium by 6 to 8 months following insertion, yet allowing easy removal within the first 4 to 6 weeks should the need arise. This technique provides a useful alternative to conventional surgical treatment in the high risk patient.
我们描述了一种新型尿道支架在12例前列腺流出道梗阻患者中的应用。所有患者均属于手术高危组，11例治疗成功，随访时间为1至11个月（中位数为9个月）。大多数患者对该手术满意，它为传统手术治疗提供了一种快速、安全且有效的替代方法。该支架由精细不锈钢编织成管状网状结构，在局部麻醉下通过联合超声和内镜控制的输送装置插入。该手术耐受性良好，支架在插入后6至8个月被上皮覆盖，但如果有需要，在最初4至6周内仍可轻松取出。这项技术为高危患者的传统手术治疗提供了一种有用的替代方法。
