Urinary infection is one of the most common complications of pregnant women.The incidence of urinary infections during pregnancy is 4%to 7%, and its incidence is no different from non -pregnancy women during sexual activity.Among the pregnant women, about 1% to 4% suffer from lower urinary tract infections, and about 0.5% to 2% suffer from upper urinary tract infection (pyelonephritis).Urology infections during pregnancy are the most common causes of admission to admission to women’s non -productive sections.Urinary infections that are not treated may cause premature birth, purulent leather, adult respiratory distress syndrome, and even death.
The causes of urinary infections in pregnancy women are prone to urinary infections.
① Increased estrogen, progesterone, and increasing the compression of the uterus, expand the renal pelvis, kidney, and ureter, leading to the retention of urine, which is conducive to the breeding of bacteria;
② The kidneys during pregnancy are in high irrigation and high filtration state, and the filtration of glucose also increases accordingly. When the re -absorption of glucose cannot increase accordingly, diabetes occurs. About 15%of pregnancy women have diabetes.Growth provides favorable survival conditions;
③ The looseness of the smooth muscle during pregnancy causes the reflux of urinary urine in the bladder.
Urinary infections during pregnancy mainly include asymptomatic bacteria, acute cystitis and acute pyelonephritis.Some of the acute pyelonephritis during pregnancy will be very serious. About 15%of pyelonephonephritis can be complicated in complication, and pregnant women are susceptible to bacterial internal toxins than pregnant women.It is endangered that the safety of maternal tires; acute renal pyelonephritis does not affect renal function during non -pregnancy, and acute pyelonephritis during pregnancy can cause a decline in the oversized glomerular filtration rate.In the case of difficult urinary infections, we must also be alert to the possibility of renal cortical necrosis and cysts around the kidney.
Because of the asymptomatic germuria women with 25%-40%of cystitis or pyelonephritis, and symptomatic urinary tract infections may occur after childbirth, it is recommended that pregnancy women take routine urine culture and find bacterial urine.The person is treated in time.It is recommended to choose sensitive antibiotics for 2 weeks, and then continue to monitor whether the bacteria urine recur.Acute cystitis during pregnancy can be treated with sensitive antibiotic treatment for 2 weeks; the treatment of acute pyelonephritis renal nephritis during pregnancy should be active. It is recommended to be hospitalized according to urine culture and drug sensitivity results.Heat, usually for 3-6 weeks, 3-7 days after the drug is discontinued, it is recommended to take urine training again, such as recurrence and timely treatment.
