[Percutaneous nephrostomy in treatment of urinary tract obstructions and malformations in the child].

Percutaneous nephrostomy (NP) is a routinely applied procedure in adults, but sparsely reported in the pediatric population. We report the treatment of acute obstructive renal diseases in 15 children aged one day to 6 years. The causes of obstruction included pelvi-ureteral junction stenosis (10 cases) by calculus or complicated by pyonephrosis, vesico-ureteral junction stenosis (2 cases), urethral valves and stenosis (2 cases) and one complex urogenital malformation. Catheter placement was performed under ultrasonographic guidance without immediate complication. NP should be considered as a primary preoperative modality for urinary tract obstruction in the pediatric population.
