ObjectiveTo explore the risk factors of urinary irritation in patients with indwelling double J-stent after treatment with flexible ureteroscope combined with holmium laser lithotripsy.

MethodsA total of 275 patients with ureteral calculi were indwelled with double J-stent after treatment with ureteral flexible ureteroscope combined with holmium laser lithotripsy.Among them, 210 patients with urinary irritation and 65 cases without urinary irritation were divided into the observation group and control group, respectively.The clinical data of two groups were collected, and the influencing factors of urinary irritation in patients with inwelling double J-stent were analyzed.

ResultsThe male, inwelling double J-stent time > 2 weeks, F6 type, abnormal ureter and diabetes were the independent risk factors of urinary irritation(P < 0.01).The preoperative controlling urinary tract infection and systematic nursing were protective factors of postoperative urinary irritation(P < 0.01).

ConclusionThe influencing factors of urinary irritation at postoperative indwelling double J-stent after ureterolithiasis are more.The appropriate type and length of the double J-stent should be selected according to the actual length of ureter, the extubation is as early as possible, the primary disease and occurrence of urinary tract infection before surgery should be controlled.
