The pathogenesis of left-side varicocele in children.

Phlebographic and manometric tests were performed in a group of 144 boys, aged 10-15 years having a left-side varicocele. From the measurements of relative blood-flow which were made between the left renal vein and the vena cava, the left external iliac vein and the vena cava, the left renal vein and the left external iliac vein, it is evident that the varicocele is only the result of the application of Bernouillé's Law to the particular characteristics of the ilio-cava and renal venous circulation.
