Laparoscopic cytoreductive nephrectomy and adrenalectomy for metachronous RCC metastases—Case report

INTRODUCTION: We report the case of a 69 y.o. man with a left solitary kidney presenting 3 tumoral masses and suspicion of a left adrenal nodular tumor. PRESENTATION OF CASE: 48 months previously, the patient underwent laparoscopic right radical nephrectomy and adrenalectomy for a clear cell renal carcinoma, with a tumor free adrenal gland. 3D laparoscopic transperitoneal left cytoreductive nephrectomy and left adrenalectomy were performed within 23 min warm ischemia with no need of post operatory hemodialysis. The pathology exam reported metachronous metastases on left adrenal gland and on a left multifocal tumoral solitary kidney from the contralateral clear cell renal carcinoma prior diagnosed and treated at this patient. DISCUSSION: Cytoreductive nephrectomy on a solitary kidney brings technical challenges for the laparoscopic approach, especially when the tumor presents as multifocal lesions. Contralateral metachronous metastases and adrenal involvement in case of renal carcinoma are scarcely presented in the literature. CONCLUSION: The “en bloc” excision of the tumoral masses optimized warm ischemia time and improved the technical approach, even if the endophytic presentation imposed difficulty.
