从1994年2月至1996年2月，采用术中超声监视下尿道内置入镍钛形状记忆合金网状支架治疗高危前列腺增生症合并尿潴留32例，疗效满意。作者认为经直肠超声监视较经腹壁超声监视更清晰。采用经直肠超声观察尿道内目的形态对选择适应症有重要意义，单纯中叶增生使尿道内目前移，或单纯一侧叶增生使尿道内口侧移者，皆不宜作支架置入治疗。测量前列腺尿道的长度，以经直肠超声法最为精确，经腹壁超声法及膀胱镜下输尿管导管测量皆有较大的误差。采用膀胱镜式置入器作支架置入缺点较多，专利支架种植器能迅速无误地将支架植入选定部位，操作更为简便。
From February 1994 to February 1996, 32 cases of high-risk benign prostatic hyperplasia with urinary retention were treated with intraoperative ultrasound-guided urethral nickel-titanium shape memory alloy mesh stent. The curative effect was satisfactory. The authors suggest that transrectal ultrasound is more clearly monitored than via abdominal ultrasound. The use of transrectal ultrasound to observe the shape of the target in the urethra is of great significance for the selection of indications. The mesial hyperplasia makes the urethra presently displaced, or simply a side of the leaf hyperplasia so that the urethral orifice migration, are not suitable for stent placement. Measuring the length of the prostatic urethra by transrectal ultrasonography is the most accurate, by abdominal wall ultrasound and cystoscopic ureteral catheter measurements are greater errors. The use of cystoscopic inserter for stent placement more defects, patented stent implants can be quickly and accurately implant the selected parts of the stent, the operation is more simple.
