Brief Summary

This study focuses on children diagnosed with intra-abdominal cryptorchidism, a condition in which the testicle remains lodged in the abdomen instead of descending to the scrotum. The scrotum is the anatomical area where testicles should reside to maintain their viability and future reproductive function. Treating this condition typically requires one or two surgeries to relocate the testicle to the scrotum while preserving its vital structures, including the vas deferens, veins, and arteries that supply it with blood. In some cases, these structures are long enough to allow for a single surgery, which is referred to as the VILO technique. However, in other cases, the structures may be too short, making it necessary to perform two operations. In the first operation, the testicle is detached and moved to the opposite side of the abdomen while preserving its vital structures. This procedure aims to allow the artery, vein, and vas deferens to elongate over the next 12 weeks with the patient's movement. After this period, a second surgery can safely descend the testicle into the scrotum. This protocol specifically includes children with intra-abdominal testicles who will undergo one of two testicular vessel-preserving techniques: the Shehata technique or the VILO technique. If, during the first laparoscopic surgery, it is determined that the testicle is long enough to be descended safely, the VILO technique will be used to complete the procedure in a single surgery. If the length is insufficient, the Shehata technique will necessitate two surgeries as outlined above. The aim of this scientific research protocol is to prospectively document all clinical and intraoperative characteristics, along with the clinical and ultrasound postoperative evolution of your son, including several months after the final surgery. This study's objective is to evaluate both techniques for successfully relocating the testicle to the scrotum and to prevent any potential damage to the testicle during surge

EXPERIMENTAL

This single-arm quasi-experimental study involves subjects aged 6 months to 7 years with intra-abdominal cryptorchidism confirmed by laparoscopy. The subjects will be non-syndromic and may present with unilateral or bilateral cryptorchidism. In the case of a short testicular pedicle, participants will undergo laparoscopic testicular descent while preserving the testicular vessels. A two-stage descent will be performed using the elongation and delayed descent technique (Shehata). Six months post-operation, testicular atrophy (assessed for safety) and the position of the testis within the scrotum (assessed for efficacy) will be evaluated through ultrasonography and clinical examination. Each subject will serve as their own control by comparing outcomes before and after the intervention

Procedure: Shehata technique

Interventions

For patients whose intra-abdominal testicle cannot easily reach the contralateral internal inguinal ring due to a short testicular pedicle, the Shehata procedure will be performed. This technique involves a two-stage laparoscopic orchidopexy that preserves the testicular vessels. In the first stage, the intra-abdominal testicle is fixed above the contralateral iliac crest using prolene vascular suture. Twelve weeks later, a second procedure is performed to position the testicle lower. This approach ensures the preservation of the testicular vessels, vas deferens, and overall circulation.
