Introduction: Classically, surgical approach for palpable undescended testis (pUDT) consists is an inguinal orchidopexy. In fact, a double incision allows an adequate mobilization of the spermatic cord and an easy dissection of a patent processus vaginalis and also to perform a subdartos pouch. For reduce potential mobility of the inguinal approach, in 1989 Bianchi and Squire proposed a transcrotal orchidopexy, using a high scrotal incision. We report our experiences and retrospectively evaluate the feasibility and postoperative success of the transcrotal approach for treatment of pUDT. Patients and Methods: From January 2012 to June 2014, 217 patients, affected by pUDT were treated at our Institution, for a total of 231 orchidopexies (203 monolateral pUDT, 14 bilateral pUDT). Patients, in whom, under anesthesia, the testis could be moved to the neck of the scrotum, have been treated with a transcrotal approach using a high scrotal incision. All patients have been clinically followed up at 1 week and at 1, 2, 3, and 6 months, at 1 year, and then annually and using scrotal sonography with color-Doppler at 2, 3, and 6 months. Results: A total of 205 pUDT (88.7%) were considered eligible for transcrotal. Eight (3.9%) pUDT, that were first approached transcrotally, have been converted to inguinal approach. At follow-up, two moderate scrotal hematomas and one inguinal hernia were noted. No recurrence or testicular atrophy was showed in transcrotal approached testes, while 2 recurrences out of 26 procedures (7.7%) were displayed after inguinal orchidopexy. Conclusions: In our experience, transcrotal approach is possible in almost 90% of pUDT. No major complication, such as recurrence or testicular atrophy, has been complained. Just 3 out of the 205 cases (1.5%) reported minor complications and 1 of which required a successful day-case procedure. Our data confirm that transcrotal orchidopexy can be considered effective, safe, and with a success rate being equivalent or better to classical inguinal approach. [ABSTRACT FROM AUTHOR]

Purpose: Stem cell factor receptor (c-kit) plays a crucial role in regulating proliferation and survival of germ cells. The aim of this study was to find the correlation between the number of c-kit positive germ cells, testicular asymmetry and histological grade in varicocele affected testis samples of adolescents.Materials and Methods: Twenty testicular biopsy samples of adolescents affected by varicocele and eight normal control testes were included. The relationship between percentage of testicular asymmetry, number of tubular c-kit positive germ cells and severity of spermatogenic failure was assessed.Results: The mean (SD; median) histological grade for spermatogenic failure in controls was 1.37(0.52; 1), while in the varicocele group, it was 2.70(1.08; 3) (P = .0052). Mean(SD; median) number c-kit positive germ cells in the control group were 20.1(2.52; 20), while in the varicocele group it was 12.35(7.16; 12.5) (P = .0059). Spearman test documented a significant positive correlation between percentage of hypotrophy and histological grade of spermatogenic failure (r = 0.5544 , 95% CI: 0.1345 to 0.8055, P = .0112) but a negative correlation with the number of c-kit positive cells (r = - 0.5871, 95% CI: - 0.8219 to -0.1817, P = .0065). Moreover, a significant negative correlation was found between grade of histological changes and number of c-kit positive germ cells (P < .0001).Conclusion: A significant correlation between hypotrophy, histological lesions and c-kit positive germ cells exists in varicocele testes. This finding suggests a possible role for c-kit in the pathogenesis of germ cell impairment in varicocele. Histological changes and lack of c-kit germ cells were also noted in testes not displaying hypotrophy. We believe that reliable markers should be found as better predictors of testicular function in adolescent with varicocele. [ABSTRACT FROM AUTHOR]

Although the outcome of newborns with surgical congenital diseases (e.g., diaphragmatic hernia; esophageal atresia; omphalocele; gastroschisis) has improved rapidly with recent advances in perinatal intensive care and surgery, infant survivors often require intensive treatment after birth, have prolonged hospitalizations, and, after discharge, may have long-term sequelae including gastro-intestinal comorbidities, above all, gastroesophageal reflux (GER). This condition involves the involuntary retrograde passage of gastric contents into the esophagus, with or without regurgitation or vomiting. It is a well-recognized condition, typical of infants, with an incidence of 85%, which usually resolves after physiological maturation of the lower esophageal sphincter and lengthening of the intra-abdominal esophagus, in the first few months after birth. Although the exact cause of abnormal esophageal function in congenital defects is not clearly understood, it has been hypothesized that common (increased intra-abdominal pressure after closure of the abdominal defect) and/or specific (e.g., motility disturbance of the upper gastrointestinal tract, damage of esophageal peristaltic pump) pathological mechanisms may play a role in the etiology of GER in patients with birth defects. Improvement of knowledge could positively impact the long-term prognosis of patients with surgical congenital diseases. The present manuscript provides a literature review focused on pathological and clinical characteristics of GER in patients who have undergone surgical treatment for congenital abdominal malformations.
