Cryptorchidism has an incidence of 0.8 - 2%, being undescendent testis nonpalpable in 20% of the cases. The latters have an increased risk of malignant transformation, infertility and epididymal malformation. Surgical treatment of nonpalpable testis is prone to failure compared to the palpable ones. Many diagnostic methods have been described; the most promising is the use of diagnostic laparoscopy which, compared to the imaging modalities, is more reliable to determine the site of the nonpalpable testis.
