[Venous drainage of the testis and the causes of the development of varicocele in children].

The article discusses the results of angiological examination of 42 children with primary and 13 with recurrent varicocele by the method of ++trans-scrotal antegrade venotesticulography. Three groups of patients were distinguished: I--with drainage of blood into the left testicular vein, II--with drainage into the left cremasteric vein, III--with simultaneous drainage into the two above-indicated veins. Incompetence of the valvular apparatus of the left testicular vein and impaired blood drainage from the left external iliac vein with the development of retrograde flow of blood along the left cremasteric vein are the most frequent causes of varicocele in children.
