A 41-year-old male presented at Emergency Department (ED) with right flank pain associated with hematuria for 3 days. Patient had a previous history of nephrolithiasis. The physical examination and blood tests were normal. Urine analyses showed haematuria > 1.000.000/μL. After clinical evaluation, a computer tomography (CT) showed right ureteral dilata¬tion caused by a 5 mm proximal stone and a distal intraluminal mass of 8 cm in length. In this setting, an ureteroscopic biopsy was performed and revealed a large polypoid lesion histologically suggestive of fibroepithelial polyp. Due to technical difficulties (intraluminal mass length and technical issue for the passage of guidewire) and after discussing all available minimally invasive options, we opted for a laparoscopic approach. Instead of ureterectomy of the affected segment of the ureter, as classically performed, we proceeded with an ureterotomy, blunt dissection of the tumor and ureterolithotomy, with complete removal of the mass. This approach did not require ureteral anastomosis and the ureteral dilatation facilitated its primary closure. No complications occurred, even after 3 years of follow-up.
一名41岁男性因右侧胁腹疼痛伴血尿3天就诊于急诊科。患者既往有肾结石病史。体格检查和血液检查均正常。尿液分析显示血尿>1,000,000/μL。经过临床评估,计算机断层扫描(CT)显示右侧输尿管扩张是由一枚5毫米的近端结石及一个长8厘米的远端腔内肿物所致。在此情况下,进行了输尿管镜活检,组织学检查显示为一个大的息肉样病变,提示为纤维上皮性息肉。由于技术困难(腔内肿物长度以及导丝通过的技术问题),在讨论了所有可用的微创方案后,我们选择了腹腔镜手术方式。我们没有像传统那样对受累输尿管段进行输尿管切除术,而是进行了输尿管切开术、钝性分离肿瘤及输尿管取石术,将肿物完全切除。该方法无需输尿管吻合,输尿管扩张有利于其一期缝合。即使经过3年随访,也未出现并发症。
