The objective of this study was to assess the feasibility of one-stage acute dilation of the nephrostomy tract with a 30F Amplatz dilator in patients who are candidate for percutaneous nephrolithotomy (PCNL), regardless of whether there is a previous renal scar to make the procedure less time consuming and more cost effective. One-stage tract dilation for PCNL was done in 100 patients with age more than 16 and kidney stone greater than 2 cm who had been referred to Labafinejad Hospital and were candidates for percutaneous nephrolithotomy (PCNL). Access time and radiation exposure time during access were compared in patients with and without history of ipsilateral open stone surgery.
