[Clinical studies of varicocele. 3: A rare venous return via Santorini's plexus in a varicocele patient. Report of a case].

A 12-year-old man was referred to our clinic because of sanguineous discharge. At the out-patient department, bilateral varicocele was found. Urinalysis showed microscopic hematuria, but no other laboratory data were abnormal. Excretion urography was normal. The retrograde phlebograph showed a rare venous return via Santorini's plexus and lumbar veins. After varicocelectomy, urinalysis improved.
