Background: Testicular tumors (TT) are infrequent in pediatric patients, representing 1% of pediatric solid tumors; benign testicular tumors (BTT) are the most common. We present a multicenter study aiming to describe the incidence, histology and surgical technique of BTT, with special emphasis on which approach could present better outcomes.

Methods: The records of pediatric patients diagnosed with BTT between 2005 and 2020 from 8 centers in 5 different countries in Latin-America, were reviewed.

Introduction: Anderson-Hynes pyeloplasty is the technique of choice for the treatment of pyeloureteral junction obstruction (PUJO) with an excellent success rate. Minimally invasive surgery has become the standard of care for the management of PUJO in children. Although it has been comparable to the open approach at all levels, its diffusion or employment in younger children has not been widely adopted.

Purpose: The Anderson-Hynes technique has been the treatment of choice for primary ureteropelvic junction obstruction in children. Laparoscopic approach has shown similar outcomes to open, with advantages of shorter hospital stay and less pain. We reviewed the experience of 11 geographically diverse, tertiary pediatric urology institutions focusing on the outcomes and complications of laparoscopic pyeloplasty.

Objective: To analyze the outcomes of patients undergoing upper-pole heminephrectomy surgery and to assess the different variables that may have an impact on outcome, specifically regarding morbidity and the need for further surgeries.

Materials And Methods: A retrospective study of patients who underwent laparoscopic upper-pole heminephrectomy for a nonfunctional moiety between August 2007 and December 2019 was conducted at 3 centers. A total of 130 patients met the inclusion criteria.

Purpose: Anterior urethral valves (AUVs) is an unusual cause of congenital obstruction of the male urethra, being 15-30 times less common than posterior urethral valves (PUVs). It has been suggested that patients with congenital anterior urethral obstruction have a better prognosis than those with PUV, with less hydronephrosis, and a lower incidence of chronic renal insufficiency (5 vs. 30%).

Purpose: Here we report the results of a review of a prospectively maintained database of the use polyacrylate polyalcohol copolymer (PPC) injection to correct grades IV and V VUR.

Materials And Methods: All children with grades IV and V primary VUR that presented with febrile urinary tract infection while on prophylaxis, in a 3-year period, were treated with a sub-ureteral injection of PPC. Institutional ethical approval was obtained.

Objective: To determine whether small intestine submucosa has the same regenerative capacity when urethroplasty is performed in injured urethras.

Methods: Our experiment was conducted in 30 New Zealand male rabbits, all of which had urethral injury. One month after the injury, the animals were randomized into a control group or a group with onlay urethroplasty with small intestine submucosa.

Purpose: Indications for laparoscopic pyeloplasty for ureteropelvic junction obstruction are steadily growing but there is still a group of young children in whom open surgery continues to be the procedure most performed by pediatric urologists. We report our results in young children and infants with dismembered pyeloplasty done through a small flank incision on an outpatient basis or during a short hospital stay.

Materials And Methods: Between April 2001 and July 2009, 45 patients with a median age of 11.
