Pediatric kidney retransplantation focused on surgical outcomes.

Introduction: Despite survival rates after pediatric kidney transplantation (KT) are on the rise it is still likely that most pediatric recipients will require more than one retransplant in their lifetime. The earlier the age at the first KT the higher is the risk of repeat pediatric kidney transplantation (RPKT).

Objective: The current study aims to analyze the outcomes of repeat pediatric kidney transplantation (RPKT) among pediatric kidney transplant recipients focusing on surgical complications and compare the outcomes of second and subsequent grafts with those of the first kidney graft.

Pediatric laparoscopic mitrofanoff procedure- preliminary results of a simplified technique.

Introduction: Laparoscopic appendicovesicostomy (LA) is a rather new technique and still a challenging procedure even for the most experienced surgeons because it requires advanced laparoscopic experience and surgical skill. The aim of this study is to analyze the short-term results and benefits of laparoscopic LA in children.

Materials And Methods: Prospective study of children undergoing LA at our institution between January 2018 and October 2021.

Laparoscopic extravesical ureteral reimplantation (LEUR) of obstructed megaureters: STEP-BY-STEP video of a simplified approach.

Introduction: In this video we aim to describe step-by-step a simplified surgical technique for the treatment of primary and secondary obstructed megaureters in children by laparoscopic extravesical ureteral reimplantation (LEUR).

Material And Methods: A transperitoneal approach is used in all cases. The distal ureter is dissected and transected at the level of the stenosis.

Laparoscopic extravesical ureteral reimplantation for correction of primary and secondary megaureters: Preliminary report of a new simplified technique.

Purpose: To describe a simplified surgical technique for the treatment of primary and secondary obstructed megaureters in children by laparoscopic extravesical ureteral reimplantation (LEUR) and evaluate the short-term outcomes.

Methods: Prospective study of children with primary and secondary megaureters treated at our institution between 2016 and 2018 by LEUR. A transperitoneal approach was used in all cases.

Hemorrhagic cystitis after hematopoietic stem cell transplantation: A challenge for the pediatric urologist.

Objective: Hemorrhagic cystitis (HC) is a serious event that can occur after hematopoietic stem cell transplantation (HSCT). Treatment goals are primarily to preserve life, and then the functionality of the bladder. There is no standard therapeutic approach for HC.

Vascular thrombosis in pediatric kidney transplantation: Graft survival is possible with adequate management.

Objective: Vascular thrombosis (VT) in pediatric kidney transplantation (KT) is a dreaded event that leads to graft loss in almost 100% of cases. In recent years, VT has become the most common cause of early graft loss. The aim of this study was to analyze our experience in diagnosis and treatment of VT and the impact of a new management protocol on patient outcome.

Kidney transplantation in children weighing 15 kg or less is challenging but associated with good outcome.

Objective: Pediatric kidney transplantation (KT) in small children is assumed to be related to potential surgical complications that may cause severe morbidity and graft loss. The aim of our study was to analyze the outcome of KT recipients weighing ≤15 kg, focusing on surgical complications, associated morbidity and mortality, as well as allograft loss.

Methods: We reviewed our retrospective institutional database for recipients of KT between January 2000 and December 2014 with body weight ≤15 kg.

Treatment of Post-transplant Lymphocele in Children.

Objective: To review our single-center experience in managing posttransplant lymphoceles in pediatric kidney recipients. Lymphoceles are well-known complications after pediatric kidney transplantation (KT). However, there is no standard treatment for lymphoceles, and the literature lacks consensus on which is the most appropriate approach.

Evaluation of the Initial Treatment of Ureteroceles.

Objective: To assess the results of the initial therapeutic approach to ureteroceles at our institution and the need for further interventions.

Patients And Methods: This is a retrospective study of all pediatric cases of ureterocele diagnosed at our center between January 2000 and December 2011.

Results: Forty-three patients were analyzed.
