Keratinizing squamous metaplasia of the renal pelvis is a rare lesion of the upper urinary tract that can occur in the context of chronic aggression to the urothelium, potentially leading to a secondary pyeloureteral junction syndrome. We report the case of a 43-year-old patient discovered intraoperatively in relation to a renal pelvis stone causing a pyeloureteral junction syndrome. The extemporaneous histological examination ruled out a malignant process, and we performed a pyeloplasty according to KUSS-ANDERSON technique. This pathology should be recognized by the urologist for appropriate management. Treatment is conservative, with extended follow-up to detect recurrences or carcinomatous degenerations.
肾盂角化性鳞状化生是上尿路的一种罕见病变，可发生于对尿路上皮的慢性侵袭过程中，有可能导致继发性肾盂输尿管连接部综合征。我们报告一例43岁患者，术中发现其患有导致肾盂输尿管连接部综合征的肾盂结石。术中组织学检查排除了恶性病变，我们根据库斯-安德森技术进行了肾盂成形术。泌尿外科医生应认识到这种病理情况以便进行恰当处理。治疗是保守的，需进行长期随访以检测复发或癌变。
