Utilization of a modified percutaneous nephrostomy tube placement: comparison to standard methodology

Patients and methods We retrospectively analysed 47 emergent percutaneous nephrostomies in dilated an non-dilated systems in 35 patients from 2001 to 2012 (range 1 months 14 years), using standard or modified technique. “Standard” technique of PCN was performed using the Seldinger or one-step techniques in dilated and non-dilated systems under Ulrasound control. “Modified” technique was performed using Seldinger technique with insertion additional needle in pelvicalyceal system, and both the Ultrasound and Fluoroscopy control was used. Percutaneous nephrostomy was considered successful if catheter was placed in renal pelvis and drained urine spontaneously.
