改良Madigan术式，采用联合膀胱切开的耻骨后保留尿道粘膜前列腺切除术的方法治疗62例前列腺增生症患者。

The resection electrode types include: a hand-crafted, temperature-resistant tungsten wire-cutting loop; a coagulating perforated resector that provides a 40% greater coagulation zone than standard cutting loops and performs cutting and coagulation simultaneously during tissue resection; a dimpled vaporization roller that offers a smoother area of vaporization than a grooved roller while providing deep-tissue coagulation; a roller ball and roller barrel, which are used for coagulation and ablation of soft tissue in the bladder and prostate (the roller ball may also be used for endometrial ablation in the uterus); and a Collings knife that allows urologists access to all areas of the prostate and is most commonly used for ureteral meatotomy and transurethral incision of the prostate.

切除电极包括：手动操作、耐受高温、钨丝切除线圈；凝固穿孔前列腺切除器，比标准切除线圈的凝固面积大出40%，能够在组织切除过程中同时进行切除和凝固；一种漩涡汽化转子，比槽式转子提供更加平滑的汽化区域，同时产生深部组织凝固；一个转子球和转子滚筒，用于膀胱和前列腺软组织的凝固和汽化(转子球还可以用于子宫内膜的消融)；一个Collings刀能够帮助泌尿科医生进入前列腺的所有区域，通常用于输尿管切除术和经尿道前列腺切开。

Methods: Ureteroscopy was used in the treatment of 25 cases of patients with urethrostenosis or urethatresia to find out the right leading direction under direct vision. The stenosis site was cut open by dilating with the ureteroscopy body combine with resection.
