Comparison of Posterior QLB and QIPB in Pediatric Undescended Testis Surgery.

This randomized, double-blind study compares the postoperative analgesic efficacy of ultrasound-guided Posterior Quadratus Lumborum Block (QLB) versus Quadroiliac Plane Block (QIPB) in pediatric patients aged 1-7 years undergoing unilateral undescended testis surgery.

Transection Versus Ligation of Internal Spermatic Vessels in Laparoscopic Fowler-Stephens Orchidopexy

This is a comparative study to see the outcome of yransection versus ligation of internal spermatic vessels in first stage laparoscopic Fowler-Stephens orchidopexy for intra-abdominal testis in assisting the descent of the testis to the base of scrotum during the second stage

Role of the Environment and Endocrine Disruptors in Child Cryptorchidism

Cryptorchidism is the most frequent congenital defect of the male newborn. It requires surgery in childhood, increases the risk of fertility disorders and cancer. As a major public health objective, it's the subject of numerous recommendations. Its frequency is increasing in some countries faster than a single genetic cause could not explain it. It may occurs in a geographic cluster. The cause of cryptorchidism involves genetic, hormonal and environmental factors. Animal studies suggest that endocrine disruptors interfere with fetal testicular migration. The aim of the study is to find out if some environmental exposition may be associated with cryptorchidism.

Learning to Palpate the Child's Testicles Using Simulation

Hypothesis is that better training of medical students in the examination of boy's external genitalia could improve the diagnosis of testicular position anomalies. To this end, investigators already have created a model to train testicle palpation and recognition of testicular position anomalies. So investigator set up a monocentric randomized controlled trial in wich the medical students will be randomized into 2 groups : a control group receiging only book-based theoretical instruction on the examination of the external genitalia and testicular position anomalies, and a mannequin group receibing, in addition to this conventionnal instruction, simulation training on the mannequin Medical students will then attend a consultation with a child whose reason for coming to the hospital is a testicular positioning anomaly. Students clinical examination will be scored by the consulting senior, and the final diagnosis retained by the student will be compared with that retained by the consulting senior. The aim is to show that medical students who have trained on this new model are better, in terms of clinical examination and diagnostic, than students in the control group.

Shehata Technique in the Treatment of Intra-abdominal Testis

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
