Mixed epithelial and stromal tumor of the kidney (MESTK) is a rare kidney tumor that tends to occur in middle-aged and older women and is characterized by a distinctive histological appearance. Most of them were incidentally detected. A 26-year-old female patient was referred to in our clinic due to intermittent left lower back pain for 2 months and left renal mass. Abdominal computed tomography showed a cystic enhanced heterogenic left renal mass about 5 cm in the largest diameter was extending from the renal pelvis to the ureter and causing gross hydronephrosis of the left kidney. The mass treated with transperitoneal laparoscopic nephroureterectomy and bladder cuff resection. Histopathological evaluation revealed MESTK. In our patient, MESTK successfully and without any complication be treated by minimally invasive surgery. We believe that the fact that the tumor can mimic the urothelial-cell carcinoma of the kidney in radiological appearance, as seen in our case, should be taken into consideration.
肾脏混合性上皮和间质肿瘤（MESTK）是一种罕见的肾脏肿瘤，多见于中老年女性，具有独特的组织学表现。大多数病例为偶然发现。一名26岁女性患者因间歇性左下背部疼痛2个月及左肾肿物就诊于我院。腹部计算机断层扫描显示，一个最大直径约5 cm的囊性强化不均匀左肾肿物，从肾盂延伸至输尿管，导致左肾重度肾积水。该肿物行经腹腹腔镜肾输尿管切除术及膀胱袖口切除术治疗。组织病理学评估显示为MESTK。在我们的患者中，MESTK通过微创手术成功治疗，且无任何并发症。我们认为，正如我们病例中所见，该肿瘤在影像学表现上可酷似肾尿路上皮细胞癌，这一事实应予以考虑。
