腹腔镜肾部分切除术治疗肾素瘤三例报告并文献复习

目的评价腹腔镜肾部分切除术治疗肾素瘤的可行性及提高对肾素瘤的认识。 方法回顾性分析从2012年1月至2020年1月我科收治的3例肾素瘤患者的临床资料。其中男性2例，女性1例，中位年龄18岁。主要临床表现为高血压和低血钾。影像学检查提示肾肿块。均行腹腔镜肾部分切除术。 结果3例患者手术顺利，术中及术后无明显并发症，未输血。所有患者术后血压恢复正常，不需服用降压药物。病理均证实为肾素瘤，随访时间1~4年，未见肿瘤复发，血压一直平稳。 结论虽然肾素瘤罕见，但如果掌握其临床特点，可早期诊断，行腹腔镜肾部分切除术治疗安全有效。

Laparoscopic partial nephrectomy for reninoma: three cases report and review of the literature

ObjectiveTo evaluate the efficacy and safety of retroperitoneoscopic partial nephrectomy for patients with reninoma and to improve the diagnosis and treatment of reninoma. MethodsThe records of 3 patients (2 males and 1 female) who underwent retroperitoneal laparoscopic partial nephrectomy at our center for treatment of reninoma between January 2012 and January 2020 were analyzed retrospectively. The median patient age was 18 years. The main clinical manifestations were hypertension and hypokalemia.The radiological images showed renal mass. ResultsAll procedures were successfully completed without conversion to open surgery. All patients did not receive blood transfusion, and there was no major complication intraoperatively or postoperatively. After surgery, the patients remained normotensive without any medication. Histopathologic examination confirmed the diagnosis of reninoma. All patients were followed up for a period of 1 to 4 years. The patients’s blood pressure remained normal and no local recurrences occurred. ConclusionsReninoma is a rare benign renal tumor. Because of the typical clinical and radiological findings, a correct preoperative diagnosis is possible in most cases. Laparoscopic partial nephrectomy is a safe, effective, and minimally invasive approach for the management of reninoma.
