ABSTRACT
Objective To evaluate the efficacy and safety of one-step dilation technique in minimally invasive percutaneous nephrolithotomy (MPCNL). Methods Clinical data of 2813 patients who underwent MPCNL by one-step dilation technique from February 2011 to March 2015 was retrospectively analyzed. Results 2813 patients were successfully underwent MPCNL by one-step dilation, including 2383 cases who were accessed by single tracts (84.71%) and 430 (15.29%) cases by multiple tracts. The mean operating time was (78.6 ± 41.1) min, the mean tract accessing time was (2.3 ± 0.8) min.The stone-free rate after one session operation was 78.59%. It improved to 91.50% one month after operation. During and after operation, 93 cases needed transfusion, 21 underwent selective renal artery embolization. Adjacent viscera damage 9 cases with pleural lesions and 1 case with colon injury, 13 cases with urinary extravasation, perirenal hematoma in 15 cases, without liver and spleen injury. Septic shock in 2 cases, who was recovered after anti-infection treatment. Conclusion One-step dilation is safe and effective technique to establish tracts in MPCNL, which can reduce X-ray exposure and operation time, but does not increase the risk of bleeding.
