There is evidence that the incidence of urolithiasis in children is increasing on a global basis. Ureteral stent placement has been widely applied prior to ureteroscopy (URS) to passively dilate the ureter and allow better access to the upper urinary tract. The objective of our study is to assess whether there is a difference in the stone free rates {SFR's} between pre- stented and non-stented patients who undergo ureteroscopic stone treatment. METHODS: A total of 124 patients who had undergone ureteroscopy (URS) lithotripsy were reviewed. The patients were divided into two groups: 64 patients without preoperative ureteral stent placement were set as group A; and the remaining 60 patients who received preoperative ureteral stent placement were set as group B. The operative time, length of hospital stay, stone- free rates, complications, and re-operation rates of the two groups were respectively compared. RESULTS: The mean operative time of group A was longer than that of group B (73.53±06.15 versus 62.35±4.69min, 0.037), the average length of hospital stay of group A was considerably shorter than that of group B 3.57±0.80 versus 6.58±1.40 d, p=0.00001937), the SFRs of group A were significantly lower than those of group B at day one postoperatively (85.9%, 55/64 versus 95%, 57/60, p=0.161. However, there were no notable differences observed in the following: SFRs between the groups at 1 month postoperatively 92.2% 59/64, of group A versus 96.6% 58/60, p=0.489, complications rates (20.3% 13/64 in group A versus 20 % 12/60 in group B, p=0.597), and re-operation rates (14.1%, 9/64 in group A versus 16.6%, 10/60 in group B, p=0.521). CONCLUSIONS: These results indicate that URS without preoperative ureteral stent placement is safe and effective for the treatment of upper urinary calculi in children.
