Photoselective vaporization of the prostate is a relatively new surgical modality for male lower urinary tract symptoms. The method has a risk of tissue damage if laser pulses miss the prostatic adenoma and travel through the irrigation fluid in the bladder. Five cases of damage to the ureteral orifices are described, with hidden orifices, intravesical prostatic adenomas and prior prostatectomy as risk factors for laser-related injuries to ureteral orifices. A laser-coagulated ureteral orifice does not seem to regain patency spontaneously, so rapid nephrostomy and subsequent DJ stenting is recommended.
前列腺光选择性汽化术是治疗男性下尿路症状的一种相对较新的手术方式。如果激光脉冲未击中前列腺腺瘤而穿过膀胱内的冲洗液，该方法存在组织损伤风险。本文描述了5例输尿管口损伤病例，隐匿性输尿管口、膀胱内前列腺腺瘤和既往前列腺切除术是输尿管口激光相关损伤的危险因素。激光凝固的输尿管口似乎不会自发恢复通畅，因此建议迅速进行肾造瘘并随后置入DJ支架。
