Idiopathic varicocele in children and adolescents--which therapeutic choice?

61 children were studied and treated between January 1986 and September 1993 for idiopathic varicocele. The aim of our study was to evaluate the advantages and disadvantages of the different techniques and to show the progression to a greater efficacy. The mean age at the time of therapy was 14 years, ranging from 7 to 16 years. All children presenting with pain or testicular asymmetry were treated. Four asymptomatic children were followed for 2 years before treatment. 36 children were treated by surgical ligature via the inguinal approach; 8 with a resection of the varicose veins as far as the tunica vaginalis. 14 children were treated by percutaneous sclerotherapy including 1 patient following unsuccessful classical surgical treatment. 12 children were treated by surgical inguinal ligature associated with peroperative phlebography and thrombosis. 56 children were reviewed postoperatively over a period which varied from 2 months to 4 years (5 lost to follow-up). For the 36 classical ligatures: 25 good results, but 9 hydroceles (5 out 8 varicose resections): 70% good results. 7 failures and 4 lost to follow-up. For the 14 percutaneous sclerotherapy: 4 technical failures (impossibility to catheterize the spermatic vein): 10 good results. For the 12 ligatures with peroperative phlebography and thrombosis: 11 good results and 1 lost to follow-up. All the above procedures were carried out at our out-patient clinic. The therapeutic choice will therefore have to take into consideration a procedure which produces the lowest morbidity rate and proves to be the most effective. The association of surgical ligature, phlebography and thrombosis meets these requirements.
