  The purpose of ureteral stent placement after transurethral ureterolithotripsy (TUL) is to help stones pass and prevent hydronephrosis and infection. However, stent-related symptoms lower patient’s QOL and, also encourage use of painkillers.  From January 2018 to June 2019, we underwent TUL without postoperative ureteral stent placement (hereinafter called Stentless TUL) on 21 patients and examined the results. The median age was 63 years old, the stone location was R2 : 2, U1 : 6, U2 : 3, U3 : 10, and the median stone major axis was 8 mm. The median operation time was 27 minutes, and endoscopic stone free was confirmed in all cases. There were no serious postoperative complications. From these results, it was considered we can perform Stentless TUL safely in some cases, and should expand the indications in the future.
