Objective  To analyze the risk factors of delayed recovery after laparoscopic prostate or bladder cancer radical surgery, and to provide information for early clinical prevention.   Methods  Three hundred and twenty-two cases of patients who underwent laparoscopic radical prostatectomy or bladder cancer surgery from September 2016 to January 2019 were enrolled in this study. The clinical data and surgical data of the patients were collected, the incidence of postoperative recovery delay was counted, and the risk factors of delayed recovery were analyzed by Logistic regression analysis.   Results   Six-noe cases of delayed recovery of laparoscopic prostate or bladder cancer were detected, the incidence rate was 18.7% (61/327); Univariate analysis found that  delayed laparoscopic recovery of prostate or bladder cancer after radical surgery and age, combined with coronary heart disease, diabetes, respiratory disease, anemia, smoking, alcohol consumption, American Society of Anesthesiologists(ASA) classification, anesthesia time, intraoperative infusion，location clarity of anatomical landmarks were related. There was a correlation between the total amount, combined epidural anesthesia and intraoperative blood transfusion (P<0.05). Multivariate logistic regression analysis found that the age, diabetes, respiratory disease, anemia, smoking, alcohol consumption, location clarity of anatomical landmarks and intraoperative total infusion were independent risk factors for delayed recovery after laparoscopic prostate cancer or radical surgery for bladder cancer (P<0.05).   Conclusion  There is correlation between delayed laparoscopic recovery of prostate cancer or bladder cancer after radical operation and age, diabetes, respiratory disease, anemia, smoking, alcohol consumption, location clarity of anatomical landmarks and intraoperative total infusion. Accurate anatomical location can reduce the risk of postoperative recovery delay. It is conducive to the recovery of the patients after operation, and the corresponding hospitalization time of the patients is greatly shortened.
