网状尿道支架治疗前列腺增生症合并慢性尿潴留
Mesh┐liketubularstenttreatmentforchronicurinaryretentioncausedbyBPH
【摘要】 1993年8月至1994年8月,作者应用由镍钛记忆合金丝编织而成的网状尿道支架治疗前列腺增生症合并慢性尿潴留患者42例。相变温度为≥30℃。采用直视可控式置放器置入。理想的支架置放位置是:支架近端距尿道内口0.3~0.5cm,支架远端距精阜0.5cm。38例患者随访1~6个月,34例(80%)效果满意。患者治疗后1、3、6个月的前列腺症状积分、最大尿流率、残余尿量均明显改善。失败的4位患者经尿道顺利取出支架,改行其它方法治疗或带管引流。本组病例术后除短时间血尿、发热及膀胱刺激症状外,无严重并发症发生。前列腺尿道长度的准确测量、支架的选择和理想的置放位置是成功的关键。
