Abstract:

Objective

To analyze the relevant risk factors affecting the hospitalization time of ureteroscopic surgery （fURS） and explore the possibility of using it as a daytime surgery.

Methods

203 patients with urinary tract stones treated with fURS in the Fifth Affiliated Hospital of Sun Yatsen University from April 2018 to March 2021 were included in the study. Univariate and multivariate logistic regression analyses were conducted to identify perioperative predictive factors for patients with postoperative hospital stay＞48 hours.

Results

Among the 203 patients with fURS， 59 patients had a postoperative hospital stay of more than 48 hours. Univariate analysis showed that the risk factors for postoperative hospitalization time＞48 hours were age （P=0.001）， surgery time （P=0.003）， previous history of urological stone surgery （P=0.012）， preoperative insertion of double-J catheter （P=0.008）， preoperative positive urinary protein （P=0.001）， and postoperative perirenal inflammation （P=0.007）. The stepwise analysis of multivariate logistic regression showed that age＞50.5 years， preoperative positive urine protein，and postoperative perirenal inflammation were independent risk factors for postoperative hospitalization time＞48 hours for fURS.

Conclusions

When patients are over 50.5 years old or have positive preoperative urinary protein， their postoperative hospitalization time is prolonged； patients aged ≦ 50.5 years and with preoperative negative urine protein can attempt fURS in the day operating room.
