Abstract: Objective: To investigate the relationship between postoperative ureteral double J stent indwelling and the occurrence of stent-adhering stones in patients with urinary calculi and hyperuricemia. Method: From January 2010 to December 2015, 240 patients with hyperuricemia who underwent urinary stone operations and double J stents indwelling were enrolled in this study. All of them were divided into four groups according to serum uric acid less or more than 500 μmol / L and stents retained two or six weeks. Patients of the former two groups with serum uric acid ＜500 μmol / L were retained for two weeks and six weeks respectively. Others with serum uric acid ＞500 μmol / L were also retained for two weeks and six weeks respectively. All patients received KUB plain film before stents were taken out. Stent-adhering stones of the lower loop were observed by cystoscopy and stones of the upper parts were observed when they were taken out. Components analysis were performed on all the calculi. Result: Among patients with stents indwelling for two weeks, the incidence of stent-adhering stones were 11.67% and 18.33% in serum uric acid less than and more than 500 μmol / L groups respectively (P＞0.05). While among patients with stents indwelling for six weeks, the incidence of stent-adhering stones were 20.00% and 61.67% in groups of serum uric acid less than and more than 500 μmol / L respectively (P＜0.05). Conclusion: Hyperuricemia is a risk factor for stent-adhering stones formation in patients of urinary lithiasis with a prolonged duration of urinary stents indwelling. It might be necessary to shorten the indwelling time of urinary stents in patients with hyperuricemia.
