Comparison of the Efficacy of Ultra-Mini PCNL, Flexible Ureteroscopy, and Shock Wave Lithotripsy on the Treatment of 1–2 cm Lower Pole Renal Calculi

Abstract

UMP, FURS, and SWL are all safe and effective in the treatment of 1-2 cm lower pole kidney stones. UMP and FURS had a better SFR than SWL, but the time of hospitalization in UMP group was longer and there were more complications in the UMP group. In addition, the operation time of FURS is longer as compared to UMP and SWL, and there is a higher rate of postoperative fever. The invasiveness and cost of SWL were lower than that of UMP and FURS, but the re-treatment rate was higher.
