[Evaluation of diagnostic factors in chronic recurrent urinary-tract infections in children. II. Clinical symptoms (author's transl)]

Abstract

2490 investigations in 171 children with chronic recurrent urinary-tract infections seen in a specialized out-patient unit for an average of 23 months demonstrated that clinical symptoms cannot be used as indicators of pyelitis or cystitis. 43% of recurrences (n=471) were completely asymptomatic. The symptomatology depends on the age of the patient and duration of the disease. Recurrences in the late course of the disease become frequently asymptomatic. Children with predominantly asymptomatic bacteriuria show pathological X-ray findings indicative of renal parenchymatous involvement as frequently as children with predominantly symptomatic recurrences.
