7. Varicocele: predilection for the left side
• The left testicular vein drains into the left renal vein at right angle
whereas the right testicular vein opens into the IVC obliquely
• The total length of left testicular vein is longer than the right
• In 15% of the cases the left testicular artery arches over the left renal vein
• The loaded sigmoid colon may compress the left testicular vein
• The left suprarenal vein drains into the left renal vein
• Incompetent valves are more common in the left testicular vein
• Occasionally the left renal vein may pass between abdominal aorta behind
& the superior mesenteric artery in front
