Does normal dimercaptosuccinic acid scintigraphy make voiding cystourethrography unnecessary after urinary tract infection?
DMSA scintigraphy results were abnormal in all 27 infants with dilating VUR except 1. This single false-negative finding should be compared with 140 unnecessary VCU investigations. This supports our hypothesis that DMSA scintigraphy results are abnormal when there is dilating VUR. Thus, a normal DMSA scan makes VCU unnecessary in the primary examination of infants with UTI.
These results suggest that H. pylori-positive patients with pruritic skin diseases may be at increased risk for development of gastric cancer, and endoscopic screening in such patients is recommended.
