Does multi-detector row CT pulmonary angiography reduce the incremental value of indirect CT venography compared with single-detector row CT pulmonary angiography?
Despite potential improved accuracy of multi-detector row CT pulmonary angiography for the diagnosis of PE, the addition of indirect CT venography increased the diagnosis of VTE in 27.4% of patients.
Although the colonization rate of ureteral stents in our study was 42.9%, the rate of urinary tract infection during the first 6 weeks after ureteral reimplantation using indwelling ureteral stents was only 4.6%. We have concluded that the clinical significance of bacterial colonization of an indwelling ureteral stent is low, and therefore, ureteral stents can be used safely.
