Left renal vein compression occurring mainly with the patient in the upright position, and being less severe or absent in the supine position, was considered to be the main cause of varicoceles. We show that left renal vein compression is, indeed, more severe with the patient in the upright than in the supine position and that it produces a left renocaval pressure gradient that is responsible for the retrograde blood flow in the left testicular vein. This pressure gradient, which was determined in the supine and semierect positions in 34 patients, increased from a mean of 3.8mm. Hg in the supine position to a mean of 7.8mm. Hg in the semierect position. |
