[Urine analysis in pregnancy].

Beside prevention routine antenatal care involves screening examinations for early diagnosis and therapy of pregnancy associated complications. Antenatal care guidelines recommend physical and especially vaginal examination, ultrasonographic evaluation, laboratory examinations, but also urine analysis. The commonly used urine analysis by dipstick can provide information on urinary tract infections, glucosuria and proteinuria. While the estimation of glucosuria has been found to be of no use for the detection of gestational diabetes and therefore is not recommended as a screening method for this disorder, urine analysis by dipstick or culture for bacteriuria or urinary tract infection followed by an antibiotic treatment is able to reduce maternal and neonatal complications. The most important role for urine analysis is the detection of proteinuria by routine dipstick examination and the quantification of proteinuria by 24 hour urin sampling in women with hypertensive disorders in pregnancy, especially in preeclampsia.
