Abstract Objective: To study clinical efficacy of extracorporeal shock wave lithotripsy in the treatment of lower urinary calculi and analysis of the factors affecting the complications. Methods: A retrospective analysis of 900 cases of lower urinary calculi in our hospital from January 2000 to October 2017 in our hospital were selected as research objects, The number of operations, the time of net operation, the time of operation, the time of hospitalization, the curative effect, the complications and the influencing factors of complications were observed by Logistic regression analysis. Results: Of the 990 cases, 410 cases were excluded from 1 times of gravel, accounting for 45.55%; 273 cases of 2 lithotripsy cases, accounting for 30.33%; 161 cases of 3 lithotripsy cases, accounting for 17.88%. The operation time was 30~70min, the average (52.39 + 3.10) min. After 6 months of follow-up, 519 cases (57.66%) were cured, 325 cases were effective (36.11%), 56 cases were invalid (6.22%), and the total effective rate was 93.77% (844/900) (P<0.05); Among 900 patients, 658 cases had complications and 242 cases had no complications. There were significant differences between body weight index, stone length diameter, stone diameter, impact times and impact energy between the two groups (P<0.05); In the Logistic regression analysis of the influencing factors of postoperative complications of lower urinary calculi, stone length diameter, stone diameter, impact times and impact energy were all the complications after lower urinary calculi surgery (P<0.05). Conclusion: The clinical effect of extracorporeal shock wave lithotripsy in the treatment of lower urinary calculi is significant. The possible factors of postoperative complications are mainly the length of the stone, the diameter of the stone, the number of times of impact, the impact energy, the greater the number of shocks, the greater the probability of complications. In clinical application, the indications and operating procedures should be strictly controlled to avoid the occurrence of complications so as to achieve better clinical efficacy.
