Percutaneous nephrostomy (PCN) catheter placement is a commonly performed procedure in the urological practice for various indications like percutaneous nephrolithotomy, pyonephrosis, infected hydronephrosis and after failed attempt of ureteric stenting. The nephrostomy catheter is usually associated with low complication and morbidity rate, but prolonged indwelling nephrostomy tube may be hazardous in some cases. We hereby report a case of squamous cell carcinoma of skin around the PCN, which was attributed to chronic inflammation and persistent irritation from a long-term neglected indwelling nephrostomy catheter for last 3 years. The patient was managed with wide local excision of skin carcinoma and ureterocalicostomy for pelviureteric junction stricture. The authors report the first documented case with aforementioned presentation.
经皮肾造瘘（PCN）导管置入术是泌尿外科临床中针对多种适应证（如经皮肾镜取石术、肾积脓、感染性肾积水以及输尿管支架置入失败后）常施行的一种操作。肾造瘘导管通常并发症和发病率较低，但在某些情况下，长期留置肾造瘘管可能存在风险。我们在此报告一例PCN周围皮肤鳞状细胞癌病例，其病因是长期忽视的肾造瘘管留置3年导致的慢性炎症和持续性刺激。该患者接受了皮肤癌广泛局部切除及肾盂输尿管连接部狭窄的输尿管肾盂造口术。作者报告了首例有上述表现的文献记载病例。
