Summary:Neðst á síðunni er hægt að nálgast greinina í heild sinni með því að smella á hlekkinn View/Open Urinary tract infections in infants are common. Unrecognized and untreated infections can have serious consequences to the kidneys and can cause serious diseases later in life. Urine specimens are often obtained by adhesive bags in young children and infants. The purpose of this study is to explore the diagnostic value of urinary bag specimens in diagnosing urinary tract infection in infants. One hundred infants were studied prospectively at the Pediatric Department of the University Hospital in Iceland regardless of underlying diagnosis. Urinary tract infection was confirmed in 7 children by either a supra-pubic aspirate or a catheter specimen. Thirty children had contaminated bag specimens. Mulitvariate regression analysis revealed that microscopic bacterial and white blood cell count correlated best with urinary tract infection (r2: 0.42 and r2 change: 0.15 respectively, p< 0.05) but a culture of the bag specimen correlated poorly ( r2 change: 0.03, p<0.05). Using bacterial count of 100.000 per ml. in a bag specimen as a cut off value, had a positive predictive value of only 46% but a negative predicive value of 99%. It is concluded that a bag specimen cannot be used reliably in diagnosing urinary tract infection in infants. A properly collected urine by either a supra-pubic aspirate or a catheter should be used for diagnostic purposes. Þvagfærasýkingar hjá ungum börnum eru algengar. Ómeðhöndlaðar þvagfærasýkingar geta leitt til varanlegra nýrnaskemmda og annarra alvarlegra sjúkdóma síðar á ævinni. Þar sem erfitt er að fá þvagsýni hjá ungum börnum, eru oft notaðir pokar til þvagsöfnunar hér á landi hjá yngstu börnunum. Tilgangur þessarar rannsóknar var að kanna gildi pokaþvags til greiningar þvagfærasýkinga hjá börnum. Á sjö mánaða tímabili voru þvagsýni frá 100 börnum yngri en tveggja ára rannsökuð á framvirkan hátt á Barnaspítala Hringsins án tillits til innlagnarástæðu eða sjúkdómsgreiningar. ...
