“…Ureteral inflammatory edema (UIE) is one of the main factors that hinder ureteroscopic lithotripsy (URSL), and leads to various complications such as prolonged surgery time (ST), reduced calculi-free rate, and postoperative ureteral stenosis (PUS) in patients with ureteral calculi (1)(2)(3). Over the last 30 years, there has been a gradual increase in reports of ureteral calculi complicated by UIE, which is mainly caused by irritation of the ureteral wall by the stone and other factors that induce an inflammatory response (4).…”

PurposeTo evaluate the relationship between endoscopic ureteral inflammatory edema (UIE) and ureteral lumen, formulate a preliminary grading method for the severity of UIE, and analyze the impact of different grades of UIE on endoscopic ureteral calculi surgery and prognosis.Materials and methodsWe retrospectively analyzed 185 patients who underwent ureteroscopic lithotripsy (URSL) for upper urinary tract stones between January 2021 and November 2021. The UIE grade and lumen conditions were assessed by endoscopic observation. The effect of UIE grade on URSL and on patient prognosis were analyzed by multiple linear regression and binary logistic regression.ResultsA total of 185 patients were included in the study. UIE grade showed a significant correlation with age, hydronephrosis grading (HG), ureteroscope placement time (UPT), surgery time (ST), hemoglobin disparity value (HDV), and postoperative ureteral stenosis (PUS) (P < 0.05). Logistics regression analysis showed a gradual increase in intraoperative UPT and ST with increase in UIE grade. The severity of UIE showed a negative correlation with improvement of postoperative hydronephrosis (IPH) and the appearance of PUS. HDV was significantly increased in patients with UIE grade 3.ConclusionsUIE grading can be used as an adjunctive clinical guide for endoscopic treatment of upper urinary tract stones. The postoperative management measures proposed in this study can help inform treatment strategy for ureteral stones.
