Abstract: Objective To analyze the risk factors of postoperative ileus after urological laparoscopic surgery. Methods From January to December in 2016, 386 patients who had undergone laparoscopic surgery in No.1 department of urology, Chinese PLA General Hospital were included, factors such as age, sex, BMI, abdominal surgery history, long term use of toxic anesthetics and steroid drugs before surgery, preoperative albumin, hospital stay before surgery, operative approach, operating time, duration of pneumoperitoneum, blood loss, minimum of postoperative hemoglobin, decrease of hemoglobin, minimum of post-operative potassium, mean of post-operative potassium, mean of post-operative potassium calcium, mean of post-operative magnesium, time of ambulation and time to first drink, were retrospectively analyzed by univariate and multivariate analysis to identify the risk factors related to the recovery of the gastrointestinal function. Results Univariate analysis indicated that operating time, duration of pneumoperitoneum, blood loss, time of ambulation and time to first drink were related to the occurrence of gastrointestinal dysfunction after urologic laparoscopic surgery (All P< 0.05). Multivariate logistic regression analysis showed that time of ambulation and time to first drink were the independent influencing factors related to the recovery of gastrointestinal function (All P< 0.05). Conclusion Time of ambulation and time to first drink are independent influencing factors that influence the recovery of gastrointestinal function after urological laparoscopic surgery.
