Abstract: ［Abstract］ Objective〖HTSS〗〓To compare the feasibility, indication and advantage of traditional laparoscopic orchidopexy(TLO) and laparoscopic assisted transcrotal orchidopexy(LATO) for cryptorchid children.
〖HTH〗〖WTHZ〗Methods〖HTSS〗〓Retrospective reviews of 83 clinical data were conduced for cryptorchid children treated with TLO(28 case) and LATO(55 case). Testis location, operative time and complications were recorded.
〖HTH〗〖WTHZ〗Results〖HTSS〗〓There were more bilateral cryptorchidism in TLO group than that of LATO group（P＜005）. All testis were delivered successfully. No intraoperative complications were observed, including bleeding, damagement of spermatic cord and bladder. There was no statistical difference in the mean operative time between the two groups（P＞005）. The mean pneumoperitoneal time was shorter in LATO than that of TLO group(P＜005). The operative time for bilateral cryptorchidism was shorter in TLO group than that of LATO group（P＜005）. No statistical difference in operative time was found by other classifications. Median followup time was 36 months. No postoperative complications were found, except for one atrophy found 24 months after TLO. No statistical difference was observed（P＞005）.
〖HTH〗〖WTHZ〗Conclusion〖HTSS〗〓LATO procedure is demonstrated with shorter pneumoperitoneal time while TLO is much more reliable in bilateral situations. Both of them are feasible and safe for management of cryptorchidism.  Staged orchidopexy may be more appliable to avoid testicular atrophy.
