During pregnancy the bodies and biological functions in the mother's body change. Normal changes in the urinary system during pregnancy can be a risk factor for many dangerous diseases.

1. Changes in the urinary system during pregnancy

1.1 Antomical changes in the urinary system during pregnancy

  • Increased renal size during pregnancy: On ultrasound detects that the length of the kidneys increases by about 1cm compared to before pregnancy. The size of the kidneys will return to normal after birth.
  • Dilated renal tank and ureter: Because of fluid retention due to obstruction of the urinary tract. This fluid retention is usually mild and is called renal tank dilion – "ureteral" during pregnancy. Stagnation of urine creates favorable conditions that cause urinary infections and can progress to severe renal tank inflammation. In rare cases, this stagnation of urine can cause kidney cramps.
  • Changes in the ermity of the kidneys can persist until 12 weeks after birth. Therefore, if you want to probe the urethrality of the urinary system, it should be done at least 12 weeks after birth.

Pregnancy

The length of the kidneys increases by about 1cm compared to before pregnancy

1.2 Changes in renal function

  • Blood flow through the kidneys and dialysis flow in pregnant women increased by about 40% compared to normal. These flow increases quite early, from the first months of pregnancy. Increasing this flow of dialysis will increase the discharge of scum. Proteinuria released will double.
  • Blood creatinine levels decreased by about 35 to 44% compared to normal values. Therefore, bio biomedification indicators in pregnant women will be different from normal people. In pregnant women, when blood creatinine levels above 80 μmol/l (0.8 mg/dl) and blood urea concentrations above 5 mmol/l (13mg/dl) may be a sign of impaired renal function during pregnancy
  • Increasing blood flow will dilute the blood flow, thereby reducing blood albumin levels, reducing blood ure and reducing the osmolysis pressure of plasma. The Urat discharge increases, which makes the normal value of the blood urat decrease. Blood tends to be slightly alkalized (pH = 7.42 – 7.44)

1.3 Translation changes

During pregnancy, the mother usually gaines about 12-15 kg. The amount of water increases by about 6-9 liters, of which mainly water is in the extra-cell cavity, about 4-6 liters. During pregnancy the volume of plasma increases almost twice and edema is normal.

2. Some diseases of the urinary system usually occur during pregnancy

  • Urinary tract infections:Usually due to decreased diy force and dilation of the urinary tract, accounting for 5-10%. Common bacteria in urinary infections are E.Coli, Proteus, Klebsiella, Enterococus … The doctor will prescribe emnical antibiotic initiated treatment, then conduct urine transplantation as an antibiotic and antibiotic therapy.

Pregnancy

Urinary tract infections are a common disease that occurs during pregnancy
  • Acute renal failure: May be caused by microvascular hemolysis plus thromboembolysis, or by acute renal failure in combination with acute fatty liver duringpregnancy (HELLP syndrome).
  • Issentoma of the uterus: Due to the release of vascular substances and possible lack of vascular causing substances leading to hypertension. This condition can cause complications in the mother such as causing seizures, young peeling vegetables, in the fetus such as fetal malnutrition, stillbirth, premature birth. This is an obstetric emergency that needs immediate treatment to ensure the safety of the mother and the fetus
  • Kidney disease that causes hypertension accompanied by proteinuria and edema that occurs from week 20 10 20 20 days on called pre-seizure . This is caused by a decrease in heart supply and an isalemia of the uterus that leads to the release of thromboblastin and causes blood clots in the vessels.
