Abstract:
Objective To evaluate the clinical features and renal morphological changes of the patients with urinary tract infection associated ureteral stent.Methods From Oct.2012 to May.2013,21 patients were divided into three groups depending on the different conditions:Group A (n=7):patients who had febrile urinary tract infections associated with ureteral stents; Group B (n =7):patients with ureteral stents but no fever; Group C (n=7):patients who had febrile urinary tract infections but no ureteral stent.The clinical data,laboratory data and 99Tcm-dimercaptosuccinic acid (DMSA) renal scintigraphy results were recorded prospectively and analyzed.Results In Group A,there were two patients had flank pain and positive costovertebral angle percussion tcnderness.The mean value of white blood cells and Hs-CRP of Group A and Group C were obviously higher than Group B (P＜0.05).The ratios of pyuria were 100.0％,71.4％ and 100.0％ in Group A,B and C.The ratios of positive urine bacteuria culture were 100.0％,42.9％ and 100.0％ in Group A,B and C.The results of 99Tcm-DMSA renal scintigraphy demonstrated the decreased uptake in the different portion of the kidneys on the sides of ureteral stents inserted in all the patients in Group A but no such changes in Group B and Group C.Conclusions 99Tcm-DMSA renal scintigraphy can be used to judge the status of urinary tract infection associated ureteral stent.The febrile urinary tract infection associated with ureteral stents always means pyelonephritis occurs and prompt treatment must be given.
