X-ray-free Ultrasound-guided Percutaneous Nephrolithotomy: How to Select the Right Patient?

ABSTRACT:

Objective

To identify factors associated with successful ultrasound guidance for each surgical step of ultrasound-guided percutaneous nephrolithotomy (PCNL).

Patients and methods

Consecutive patients undergoing PCNL between March 2015 and June 2016 were prospectively enrolled. An attempt was made to use ultrasound guidance in renal access, tract dilation, and nephrostomy tube placement for each patient. For steps during which ultrasound guidance was unsuccessful, fluoroscopic screening was applied. Regression analysis identified patient characteristics associated with successful use of ultrasound guidance.

Results

A total of 96 patients composed this cohort, with a mean body mass index of 28.7 kg/m². Mean stone size was 33.1 ± 18.9 mm, and no hydronephrosis
