Objective To investigate the safety and effectiveness of laparoscopic orchiopexy assisted by needle grasper hydrodissection for cryptorchidism.Methods From September 2020 to September 2022,21 children with cryptorchidism on 25 sides underwent laparoscopic orchiopexy assisted by needle grasper hydrodissection in our department.The water injection function of needle grasper was applied to inject normal saline into the retroperitoneal space to fully separate the retroperitoneum from the vas deferens and spermatic cord,establishing a liquid barrier to protect the vas deferens and spermatic cord.Then the retroperitoneum was bridge-likely cut off with the assistance of needle grasper.The vas deferens and spermatic cord were completely released in accordance with the principle of integrity and non-destructiveness,then the testes were successfully induced and fixed.Results During the operation,15 cases of inguinal cryptorchidism and 6 cases of intra-abdominal cryptorchidism were confirmed.There were 17 cases of unilateral cryptorchidism and 4 cases of bilateral cryptorchidism.All the 25 testes were successfully re-located into the dartos pouch of the scrotum under laparoscopic guidance.The operation time was 35-75 min(mean,45.1±14.3 min),and there were no surgical complications.During follow-ups for 12-24 months in 21 cases,the testicles were found located in the scrotum without retraction,atrophy,incision infection,incision hernia,or inguinal hernia.Conclusions Needle grasper hydrodissection assisted laparoscopic orchiopexy can effectively protect the vas deferens and spermatic cord.The operation is simple,safe,and effective.
