Right-sided varicocele associated with situs inversus

In the overwhelming majority of cases, varicocele appears in the left scrotum, the reason being the anatomical dissimilarity of the two sides. In patients with right-sided or bilateral varicocele, further investigation to rule out a retroperitoneal pathology, especially neoplastic, is indicated. On rare occasions, however, a vascular anomaly as the underlying pathology must be considered. A patient is presented with a complete situs inversus accompanied by a right-sided varicocele. Intraoperative right internal spermatic phlebography revealed that this vein drained into the right renal vein, and valvular incompetence at their confluence was the etiology of the disease. Intraoperative internal spermatic phlebography in patients with right-sided or bilateral varicoceles is recommended as the simplest and safest means to demonstrate the etiology of this disease.
