[Renal autotransplantation for the treatment of nutcracker phenomenon which caused varicocele rupture : a case report].

A 31-year-old man visited our hospital complaining of swelling in the left scrotum. Five days previously, he had felt sudden pain in the left lower abdomen and noticed swelling in the left scrotum. He had been suffering from intermittent gross hematuria and left flank pain for 1 year. An elastic hard mass was palpable in the left scrotum. Scrotal hematoma and marked dilation of left renal vein and left gonadal vein were revealed by computed tomography. A diagnosis of varicocele rupture secondary to nutcracker phenomenon was made. One month later, he underwent retroperitoneal laparoscopic donor nephrectomy and subsequent renal autotransplantation into the left iliac fossa. The post-operative course was uneventful. Gross hematuria was resolved 3 days after the operation, and swelling in the left scrotum was resolved within 6 months of the operation. Surgical intervention to treat nutcracker phenomenon is considered controversial. We believe that our procedure is a reliable option for surgical treatment for nutcracker phenomenon.
