LOPEZ E, PEDRO-JOSÉ   et al. Laparoscopic Approach in the Management of Non-palpable Testes. Rev. chil. pediatr. [online]. 2009, vol.80, n.3, pp.225-230. ISSN 0370-4106.  http://dx.doi.org/10.4067/S0370-41062009000300003.

Objective: To evaluate our experience in laparoscopic management as the procedure of choice for nonpalpable testes (NPT). Methods: Review of charts of all boys with NPT who underwent laparoscopy (January 2000 December 2005). Demographic data, ultrasound (US) results, surgical details were documented. Results: Sixty-three patients (74 NPT) were identified; 25 left, 26 right and 12 bilateral. Mean age at diagnosis was 3.6y (lm-13y). Thirty-seven cases had a pre-op US; in 29 (78%) the testis was not found; 7(22%) an intra-canalicular teste was described. All were impalpable at evaluation under anesthesia (EUA). Mean age at surgery was 4.9y (2 m-17 y). Laparoscopic findings were; intra-abdominal teste (n = 24, 33%), vanishing teste (n = 12, 16%) and vas-vessels entering inguinal ring (n = 38, 51%). 16/24 underwent a 2-stage Fowler-Stephens orchyopexy and 8/24 a laparoscopic-assisted single stage orchypexy. When vas-vessels entered inguinal ring, inguinal exploration was performed; 23 cases underwent orchyopexy; 13 had orchydectomy (atrophic-vanishing). After follow-up, 3 testes are atrophic. Conclusions: 36/74 NPT were not in the inguinal canal (24 intraabdominal and 12 vanishing). When vas-vessels entered inguinal ring, 13 were vanishing-atrophic and not identifiable (EUA or US). Hence, in 49 cases (66%) laparoscopic exploration was critical in teste location, therefore this approach may be the procedure of choice for NPT.
