Q

Pathogenesis of Left side affection in SIDE AFFECTED in Primary Varicocele in Etiology of Varicocele

A
  1. The right angled termination of the left spermatic vein into the left renal vein, impedes the venous return, in contrast to the oblique termination of the
    right vein into the IVC.
  2. The left renal vein passes anterior to the aorta & posterior to the superior mesenteric artery (nutcracker action).
  3. Ineffective anti-reflux valves at the junction of the testicular vein and renal vein
  4. The lower position of the left testes & the higher position of the left kidney
  5. Compression of the left testicular vein by the heavily loaded pelvic colon
