Renal oncocytomas are asymptomatic, benign tumors often encountered incidentally on various imaging modalities. Renal oncocytomas comprise 5-7% of primary renal neoplasms and are derived from cells of the distal renal tubule. We present a case report of renal oncocytoma in a 22-year-old male having right-sided flank pain and symptomatic gross hematuria with a giant urinary bladder clot retention. The tumor was excised, and the patient underwent laparoscopic partial nephrectomy. Typical features of renal oncocytoma were observed upon histopathological examination of the resected specimen. The patient was catheterized, and bladder irrigation with clot retraction was performed.
肾嗜酸细胞瘤是无症状的良性肿瘤，常在各种影像学检查中偶然发现。肾嗜酸细胞瘤占原发性肾肿瘤的5%-7%，起源于远端肾小管细胞。我们报告一例22岁男性肾嗜酸细胞瘤病例，该患者右侧胁腹疼痛，出现有症状的肉眼血尿，并伴有巨大膀胱血凝块潴留。肿瘤被切除，患者接受了腹腔镜下肾部分切除术。对切除标本进行组织病理学检查时观察到肾嗜酸细胞瘤的典型特征。患者接受了导尿，并进行了膀胱冲洗和血凝块回缩处理。
