Abstract
The patterns of venous drainage of the testis and scrotum have been evaluated in patients with varicocele by a variety of radiological procedures, including left renal venography, and at the time of operation by ascending venography and retrograde injection of contrast medium into prominent varicosities. These studies have allowed classification of the system of veins involved in the condition into several groups, including involvement of the internal spermatic vein alone, pure cremasteric varicocele, mixed internal spermatic and cremasteric varicosities in one or both systems with valvular incompetence or mere dilatation without apparent incompetence of valves. As a result, an anatomical approach to the surgical management of varicocele is suggested which attempts to place the operative treatment on a more rational basis appropriate to each case.
