[Complications in laparoscopy renal surgery in pediatric age: analysis of our experience and literature review].

Introduction: The development of the minimally invasive surgery in pediatric age has been slower than in the adult age since their advantages are not so clear. The learning curve and the complications presented during this period, as well as the type of material used has been the factors that have contributed to this fact.

Objective: We collected our experience and the complications presented in renal laparoscopic exegesis surgery, adding a review of the published literature to date.

Cystic dysplasia of the rete testis: case report.

Cystic dysplasia of the rete testis is a rare cause of paediatric scrotal mass often associated with other genitourinary tract anomalies. This benign congenital lesion is the result of a developmental disorder of the union of the Wolffian duct and the seminiferous tubules, and represents a diagnostically challenging condition. Cystic dysplasia of the rete testis should be considered in the differential diagnosis of paediatric scrotal masses.

[Is effective the initial management of primary nonrefluxing megaureter with double-J stent?].

Background: Initial management of patients with primary nonrefluxing megaureter (PNRM) associated with impaired renal function or with high risk rate of decreased kidney function can be a dilemma. We present our experience in the use of double -J stent in these patients to evaluate the role as a method to decompressing the system, to prevent function loss or to temporize surgical treatment.

Methods: In the period 1996-2006 27 patients were diagnosed of PNRM.

[Minimally invasive endourological management of urinay tract calculi in children].

Background: The urinary tract calculi in children is a very unfrequent problem in the pediatric age group. Endourology plays a major role in pediatric surgery. We reported our experience in endoscopic management of pediatric calculi.
