[Percutaneous paracentric nephrostomy in acute occlusion of upper urinary tracts in children].

The article presents the analysis of using percutaneous paracentetic nephrostomy (PPN) in diagnosis and treatment of 31 children aged from 11 months to 15 years with renal colic. Decompression of the kidney arrested the colic and inflammation progression, allowed to study renal function, to determine causes of acute supravesical occlusion. Seven patients with associated pelvic and ureter stones as a cause of acute occlusion with obstruction in the peripelvic ureter site have undergone one-stage reconstructive operations with stone removal. In diagnosis of isolated pelvic stones (4 children) nephrolithoextraction through nephrostomy canal was performed. Pilot experience with PPN in renal colic has demonstrated good results and allowed to expect good perspectives of introduction of minor invasive methods in urgent practice of pediatric urology.
