Abstract: ［Abstract］ Objective To explore and compare the efficacy of tubeless percutaneous nephrolithotomy （PCNL） and ureteroscopic lithotripsy （URL） in the treatment of upper urinary calculi. Methods From February 2017 to March 2019， 60 cases of upper urinary tract calculi in our hospital were divided into PCNL group and URL group according to different surgical schemes， 30 cases each. The operation related indexes （operation time， phase I stone clearance rate， hemoglobin reduction， indwelling time of urinary catheter and hospitalization time）， postoperative pain degree， use rate of analgesics and incidence of postoperative complications were compared between the two groups. Results There was no significant difference in operation time， hemoglobin reduction， indwelling time of urinary catheter and hospitalization time between the two groups （P>0.05）|the stone clearance rate of stage I in PCNL group was higher than that in URL group （P<0.05）|the pain score and the use rate of analgesics in PCNL group were no significant difference compared with that in URL group （P>0.05）|there was no significant difference in the incidence of postoperative complications between the two groups （P>0.05）. Conclusion Compared with URL， PCNL without cannulated microchannel has a higher clearance rate of upper urinary tract calculi in stage I. It can effectively reduce the degree of pain and the use of analgesics， reduce the occurrence of complications， shorten the indwelling time of urinary catheter， and promote the recovery of patients. It is worthy of clinical promotion and application.
