RESUMO
BACKGROUND: Minimally invasive surgery for paediatric adrenal tumours has evolved, but robot-assisted laparoscopic adrenalectomy (RALA) in children remains poorly studied. The current prospective study aims to demonstrate the safety and efficacy of RALA in treating children with adrenal tumours. METHODS: A prospective institutional analysis of children presenting with neuroblastic and endocrine tumours treated with RALA was undertaken over a six year-period. For each child, clinical parameters were collected relating to diagnosis, surgery and outcomes. RESULTS: A total 50 RALA were performed; 23 for unilateral neuroblastic tumours (87 % neuroblastomas) and 27 for endocrine tumours. Eight neuroblastic tumours (35 %) had image-defined risk factors (all due to tumour invading the renal pedicle). Median length of stay was two days. Resection margins were macroscopically clear in all cases. After median follow-up of 2.9 years (1.6-3.9), two children are under treatment for metastatic relapse (high-risk disease) and three died due to refractory disease. Sixteen children had endocrine tumours: pheochromocytoma (n = 13), or bilateral nodular adrenocortical hyperplasia with Cushing's syndrome (n = 14). One child required non-emergent conversion, and one complication occurred (grade IIIb) after median follow-up of 3.3 years (1.0-5.7). CONCLUSIONS: The current study is the largest reported experience in the literature and confirms the safety and effectiveness of RALA in carefully selected children with adrenal tumours. Through an iterative process and in the setting of a dedicated paediatric robotic surgical team indications have been clarified and extended. The current study confirms RALA has particularly utility in patients with severe disease (IDRF + metastatic neuroblastomas) or genetic predisposition syndromes.
RESUMO
PURPOSE: To evaluate UDR reliability, sensitivity, specificity and to identify the best treatment basing on UDR among single or double endoscopic injections and ureteral reimplantation. METHODS: Data of patients affected by primary VUR and treated by endoscopic injection over a 10 years period were retrospectively analyzed. Two radiologist attributed reflux grade and UDR on voiding cystourethrogram twice and blinded. Follow-up focused on resolution after 1 or 2 endoscopic injections. Relation between UDR, reflux grade and outcomes were analyzed. RESULTS: Patient enrolled were 198. Low grade VUR was present in 24.8%, grade 3 in 41.6%, grade 4-5 in 33.6%. Resolution after one injection was obtained in 88 patients; among 110 not resolved 104 cases had a second injection. Success after 2 injections was reported in 138 cases. UDR showed a higher reliability compared with reflux grade both in intra than inter-reader measurement (ICC > 90%). Success after 1 or 2 injections was reported for UDR < 0.33 and UDR < 0.47 respectively. CONCLUSION: UDR shows to be a more reliable measurement that allows for an objective estimation of VUR severity and prognosis. It represents a quantitative parameter that might be useful to identify patients who may benefit endoscopic or surgical treatment, avoiding unnecessary under or over-treatment.

PURPOSE: Since bladder neck dextranomer/hyaluronic acid copolymer (Deflux) injections can improve urinary incontinence of various etiologies, we hypothesized that incontinent children with bladder exstrophy-epispadias complex would benefit from dextranomer/hyaluronic acid copolymer. We aimed to analyze dextranomer/hyaluronic acid copolymer efficacy and predictors of treatment success in bladder exstrophy-epispadias complex. MATERIALS AND METHODS: Incontinent bladder exstrophy-epispadias complex children aged >4 years undergoing dextranomer/hyaluronic acid copolymer injections in our hospital between October 1997 and January 2021 were included. Medical history, continence, and bladder capacity before injections were recorded. Postoperatively, patients were categorized as "dry," "significantly improved," or "failure." Postoperative complications, bladder emptying mode, and bladder capacity were reported. Failure-free survival was estimated by Kaplan-Meier models. RESULTS: Altogether, 58 patients (27 male epispadias, 9 female epispadias, 22 bladder exstrophy) underwent 105 injections at median age of 8.5 (interquartile range 5.8-12) years. Previous bladder neck reconstruction had been performed in 38 (66%) and 33 (57%) received multiple injections. Complications occurred in 9%. Five-year failure-free survival was 70% (standard error 9.1) in males epispadias compared to 45% (9.0) in females and exstrophy patients (P = .04). Previous bladder neck reconstruction associated with improved 5-year failure-free survival in females and exstrophy patients (58%, SE 11) but not in male epispadias (75%, SE 11). CONCLUSIONS: Dextranomer/hyaluronic acid copolymer injections provided satisfactory and lasting continence in over half of bladder exstrophy-epispadias complex patients. While injections were successful in male epispadias regardless of bladder neck reconstruction timing, results were better in bladder exstrophy and female epispadias after previous bladder neck reconstruction.

BACKGROUND: Ureteral anomalies distal to the Uretero-Pelvic Junction (UPJ) belong to the wide spectrum of congenital anomalies of the kidney and urinary tract (CAKUT). They can cause severe obstruction requiring a detailed anatomical depiction to define the surgical approach. Up to date, ultrasonography, voiding cystourethrography and scintigraphy are considered the gold-standard diagnostic tools to study obstructive anomalies of the urinary tract, however, they do not provide accurate ureteral anatomical details. The aim of our study was to evaluate the concordance between functional magnetic resonance urography (fMRU) and intraoperative findings to define ureteral anomalies distal to UPJ. METHODS: Pediatric patients with ureteral anomalies distal to the UPJ who underwent surgery after performing fMRU were retrospectively collected. Surgical data were compared with radiological results. The concordance was assessed considering both pathological and non-pathological urinary tracts and was calculated by means of the Cohen's kappa coefficient. fMRU diagnostic accuracy was defined by sensitivity, specificity, and binomial exact confidence intervals. RESULTS: We included 46 patients. The sensitivity and specificity of fMRU were 98.0% and 83,3%; positive predictive value 90,4%, negative predictive value 96.2%. The concordance between surgical findings and fMRU was 92,3%, with a k Cohen's coefficient of 0.83 (excellent). CONCLUSIONS: Our study demonstrates the excellent agreement between fMRU and surgical findings in the definition of ureteral anomalies distal to the UPJ in children. Thus, it could be considered a valid imaging technique in the preoperative planning as it provides the surgeon with important information regarding the etiology and site of the obstruction.

Burn injuries are distressful and shocking events, which can lead to noteworthy sequelae on metabolic markers and organs. Such traumatic accidents do occur every so often in both adult and pediatric populations, requiring prompt and adequate treatments. Notably, scald injuries occur due to direct contact with hot liquids and these are the most common cause of burns in early childhood. Herein, we report on an 18-month-old boy admitted to our pediatric surgery unit for an extensive scald injury, who has experienced an unusual esophageal stricture following the traumatic event.
