OBJECTIVE: To evaluate the effect and double-J stent indwelling time in the treatment of acute upper urinary tract infection caused by ureteral calculi.
METHODS: A prospective non-randomized controlled study was carried out. From January 2011 to August 2015, a total of 142 patients treated in Department of Urology of Shanghai First People's Hospital for ureteral calculi with systematic inflammatory response syndrome were divided into double-J stent indwelling 7 days group (n=63) and double-J stent indwelling > 7 days group (n=79). The preoperative routine blood test, urinalysis, and urine culture, the urinalysis and urine culture immediately after double-J indwelling, and the routine blood test, urinalysis, and urine culture 7 days after indwelling were compared between the two groups. Postoperative complications after lithotripsy were analyzed.
RESULTS: There were no statistically significant differences in preoperative blood white blood cell (WBC) count, urine WBC count, and positive bacterial culture between the two groups (all P>0.05). Seven days after double-J stent indwelling, significant improvement was seen in both the 7 d group and the >7 d group in blood WBC count, urine WBC count, and positive urine culture [(8.1±1.7) vs (14.8±3.1) ×10(9)/L, (356±44) vs (3 077±643)/μl, 1.6% vs 52.4%; (7.9±1.1) vs (15.1±3.8) ×10(9)/L, (363±52) vs (3 122±805)/μl, 3.8% vs 48.1%], and infection was managed effectively, while no statistically significant inter-group differences were observed. There was no significant difference in stone clearance rate between the two groups (96.8% vs 96.2%, P>0.05). There was no significant difference in the incidence of postoperative complications, especially infectious complications (all P>0.05).
CONCLUSIONS: Indwelling double-J stents for 7 days could effectively manage the infection in patients with acute upper urinary tract infection secondary to ureteral calculi. These patients can be treated with lithotripsy safely. The time of double-J stent indwelling could be shortened.
