Urinary tract infections occur during pregnancy are common and are apparently due to the slow urine flow, which is caused by the hormonal dilation and weakened peristalsis of the ureters and the pressure that the widening uterus exerts on the ureters. In about 15% of all pregnancies there is a asymptomatic bacteriuria, which develops in some cases symptomatic cystitis or pyelonephritis. but a manifest urinary tract infection is not always preceded by an asymptomatic bacteriuria. Asymptomatic bacteriuria, urinary tract infection and pyelonephritis increase the risk of preterm labor and premature rupture of membranes.
(Urinary tract infections (UTIs).) Urinary tract infections occur during pregnancy frequently and are apparently due to the slow urine flow, which is caused by the hormonal far position and attenuated peristalsis of the ureters and by the pressure that the widening uterus exerts on the ureters. In about 15% of all pregnancies there is a asymptomatic bacteriuria, which develops in some cases symptomatic cystitis or pyelonephritis. but a manifest urinary tract infection is not always preceded by an asymptomatic bacteriuria. Asymptomatic bacteriuria, urinary tract infection and pyelonephritis increase the risk of preterm labor and premature rupture of membranes. Diagnostic urinalysis and urine culture done at the first examination routine urinalysis and urine culture to clarify asymptomatic bacteriuria. Pregnancy does not affect the diagnosis of symptomatic urinary tract infection. Treatment Antibiotics such as cephalexin, nitrofurantoin or trimethoprim / sulfamethoxazole cultures to confirm the healing success and occasionally growth inhibitory Treatment Treatment of symptomatic urinary tract infection is not changed by the pregnancy except that drugs that could harm the fetus to avoid (see table: Some medicines with adverse effects during pregnancy). Since asymptomatic bacteriuria can lead to pyelonephritis, it should be treated with antibiotics, which are also used in acute urinary tract infection. The choice of antibiotic depends on the individual and local sensitivity and resistance layer; Experience has shown that the antibiotics are a good first choice: Cephalexin nitrofurantoin trimethoprim / sulfamethoxazole After treatment have to be performed to demonstrate the healing success. had in pregnant women with pyelonephritis or more than a urinary tract infection, a growth inhibitory therapy, usually with trimethoprim / sulfamethoxazole be necessary (before 34 weeks) or nitrofurantoin for the remainder of pregnancy. In pregnant women with bacteriuria with or without urinary tract infection or pyelonephritis, a urine culture should be applied monthly. Summary Asymptomatic bacteriuria, urinary tract infection and pyelonephritis increase the risk of preterm labor and premature rupture of membranes. Initial is treated with cephalexin, nitrofurantoin or trimethoprim / sulfamethoxazole. Cultures to confirm the healing success can be created. In pregnant women who had a pyelonephritis or more than a urinary tract infection, should be a growth inhibitory therapy, usually with trimethoprim / sulfamethoxazole should be considered (before 34 weeks) or nitrofurantoin.
