Idiopathic varicocele in children. Epidemiological study and surgical approach

Background Idiopathic varicocele is one of the most frequent conditions capable of reducing male fertility. Early detection and adequate therapy make it possible to prevent the infertility related to this disease. Methods. The results of a clinical and instrumental (Doppler) epidemiological study conducted in 766 subjects of peripuberal age are reported. The clinical and functional results in those subjects undergoing surgery for varicocele. The technical options adopted for varicocele correction were either microsurgical venous bypass between the internal spermatic vein and the inferior epigastric vein or laparoscopic ligation of the internal spermatic vein in a retroperitoneal site. Results. The epidemiological investigation conducted by the authors showed a high incidence (48.5% including the subclinical forms) of idiopathic varicocele in the male population. The clinical and instrumental (Doppler) follow-up carried out at 3, 6 and 18 months postoperatively showed satisfactory results, particularly in patients submitted to microsurgical venous bypass, with a relapse rate of only 2.6%. Conclusions. On the basis of the results obtained, the authors advocate an early surgical approach to varicocele. Among the corrective techniques available, microsurgical treatment is, in the authors' opinion, capable of yielding the best clinical and functional results.
