To investigate the complications of minimally invasive lithotripsy in urinary system calculi.

The clinical data of 136 patients with urinary calculi who were treated in our hospital from December 2014 to December 2016 were analyzed by retrospective analysis. All patients were treated with minimally invasive lithotomy. Postoperative complications and the influencing factors, and postoperative risk factors were analyzed by logistic regression.

Of the 136 patients, 51 cases of postoperative complications, accounting for 37.5%, of which 42 (30.9%)cases of fever, 3 cases of infection(2.2%), 3(2.2%) cases of stones, 1 case of delayed bleeding (0.7%), 1 case of renal pelvis perforation (0.7%), 2 cases of peripheral organ injury (1.5%), the highest proportion of fever complications were found, and postoperative fever complications were univariate analysis. There was significant correlation between the factors such as age, diabetes mellitus, operation time, urinary culture and urinary white blood cells (P<0.05), and had no significant correlation with the factors such as gender, hydronephrosis and hypertension logistic regression analysis showed that stone surface area, stone shape and operation time, intraoperative blood loss and other factors were independent risk factors for postoperative fever of urinary tract stones (P<0.05).

The incidence of fever, infection, residual stones and other complications is easy to occur after minimally invasive lithotripsy. The surface area, shape and operation time of calculus are the independent risk factors of postoperative fever. Complications of risk factors for effective control, enhance the prognosis of patients.
