Objective: to improve the results of diagnosis and treatment of patients with intra-abdominal cryptorchidism by developing a new approach to surgical treatment with the introduction of laparoscopic technique and live tissue welding technology; to conduct a comparative analysis of the performed surgery using the various laparoscopic techniques in children with this condition; to analyze the long-term results by testicular ultrasonography in different age groups.

Materials and methods. The paper summarizes experience of treating of 119 patients with suspected intra-abdominal cryptorchidism, who were admitted to the surgical department of the Zhytomyr Region Children’s Clinical Hospital between 2000 and 2015. The interventions were performed using the laparoscopy of the company «Karl Storz», pediatric model, and apparatus for live tissues welding. Anaesthetic stations that was using during surgical interventions: FELIX VISIO Integra and Leon MEIMEN-LOVENSTEIN). Ultrasound examinations were carried out by using the ultrasound devices with Doppler effect («Philips HD 11XL» with color Doppler and «Siemens G50» with color Doppler) that permitted to assess the state of scrotum, spermatic cord and testicles blood circulation before surgery. The diagnosis of testicular hypoplasia (by measuring its width and length) was conducted by the method of Vasiliev A. et al., 2008.

Results. The study included 29 children (24%) who underwent one-stage orchiopexy. In total 43 (36%) children who were operated with single stage Fowler-Stephens orchiopexy. The video-assisted orchipexy (combination of diagnostic laparoscopy plus inguinal access) was applied in 23 (19.5%) children. The 24 cases that makes up 20.5%, when the testicles were not vizualised intraabdominally or hypoplasia, aplasia or anorhizm was detected during the intervention, were excluded from the comparative analysis of surgical methods.

Conclusions. Comprehensive assessment of the treatment efficacy of children with intra-abdominal cryptorchidism in index and control groups showed that the one-stage orchiopexy with using the tissue preservation high-frequency live tissue welding permitted to significantly improve the outcomes in patients with this pathology, since testicular hypoplasia was observed only up to six months of age in two patients (total 29 patients, p<0.05), and after one year of age was not identified in any case. The follow-up showed that resistance index, PSV and EDV in all groups of patients up to one year of age were within normal limits. Thus, the study of the efficacy of surgical treatment of patients with intra-abdominal cryptorchidism demonstrated the advantage of one-stage laparoscopic orchiopexy combined with with live tissue welding technique.
