Abstract

Since laparoscopy has been proposed in the management of the nonpalpable testis (NPT), this technique has been widely diffused among pediatric surgeons and urologists, but its application is still debated. We conducted a retrospective review to highlight how diagnostic and surgical indications for laparoscopy are selective and should be targeted to individual patients. From 2015 to 2019, 135 patients with NPT were admitted to our surgical division. Of these, 35 were palpable on clinical examination under anesthesia and 95 underwent laparoscopy. The main laparoscopic findings considered were: intra-abdominal testis (IAT), cord structures that are blind-ending, completely absent, or entering the abdominal ring. The patients’ mean age was 22 months. In 48 cases, an IAT was found, and 42 of these underwent primary orchidopexy while 6 had the Fowler–Stephens (FS) laparoscopic procedure. Of the first group one patient experienced a testicular atrophy while two a reascent of the testis. In the FS orchidopexy group, one patient had testicular atrophy. Cord structures entering the internal inguinal ring were observed in 35 children, and all were surgically open explored. In 3 cases of these, a hypotrophic testis was revealed and an open orchidopexy was executed. In the remaining the histological examination revealed viable testicular cells in four patients and fibrosis, calcifications, and hemosiderin deposits in the others. Eleven patients presented with intrabdominal blind-ending vessels and one a testicular agenesia. A careful clinical examination is important to select patients to submit to laparoscopy. Diagnostic laparoscopy, and therefore, the anatomical observation of the testis and cord structures are strictly related to develop a treatment plan. In IAT, many surgical strategies can be applied with good results. Laparoscopy offers a concrete benefit to the patient.
