title: Rapid percutaneous nephrostomy catheter placement in neonates with the trocar technique.
abstract: OBJECTIVE
  The purpose of this study was to assess the efficacy of a modified percutaneous nephrostomy procedure for grade III-IV hydronephrosis in neonates.
  
  
  METHODS
  Eleven neonates (five girls, six boys) with a mean age of 13.7days±9.9 (SD) (range, 4-28days) with pronounced hydronephrosis had percutaneous nephrostomy using a modified procedure. In all patients, percutaneous nephrostomy was performed with a trocar catheter under ultrasound guidance and then the catheter was placed into the collecting system without prior dilatation.
  
  
  RESULTS
  Technical success was achieved in all patients. There were no major procedure-related complications. There was no perirenal hematoma on control ultrasound examinations and no hematuria was observed after the procedure. The median drainage time was 75days (range: 42-120days). Two children had urinary tract infection, which was controlled by using antibiotics.
  
  
  CONCLUSIONS
  The trocar nephrostomy is a practical and feasible method, which can be used for neonates with grade III-IV hydronephrosis.
