Urinary tract infection is a common female, pyelonephritis is one important disease, if we can control the condition is stable, asymptomatic, with normal renal function, consider pregnancy and birth.
In the decision before pregnancy, need to check (1) had no urinary tract malformation, obstruction, calculi, polyps, perticulum and disease, gynecological inflammation disease, which is an important cause of recurrent urinary tract infection. (2) check whether the renal function is normal, if uremia has occurred, it is not pregnant.
The urinary tract of chronic pyelonephritis has long-term repeated infection history, as well as the changes of kidney structure, tubulointerstitial damage, such as deformation of renal cortex scar, calyx, nocturia, urine specific gravity reduced, to the hospital for examination confirmed.
Renal blood flow in pregnant women was significantly increased, in glomerular hypertransfusion and hyperfiltration state, with patients with water and sodium retention, hypercoagulable state, the kidney in anatomical structure volume, pelvic inflammation and renal calices and dilatation of the ureters, these changes may cause chronic nephritis or primary kidney the aggravation of lesions and even worse renal insufficiency. Such as chronic nephritis patients only urine abnormalities, pregnancy process can be passed, but even if only proteinuria, pregnancy complications and the incidence of stillbirth of pregnant women is higher than normal, it is best not to put pregnant patients with chronic nephritis. If you want to get pregnant, you must get the consent of the doctor:
(L) chronic nephritis has been stable for more than two years, two years without hematuria, proteinuria less than 0.5 grams per day.
(2) normal renal function.
(3) no urinary tract infection, no hypertension.
(4) the pathological types were mild, such as small lesions, minor lesions, viscosity membrane hyperplasia and early membranous nephropathy. Chronic nephritis patients after pregnancy should rest, regularly check blood pressure and urine routine, renal function, active prevention and treatment of hypertension in pregnancy; late pregnancy should be hospitalized for treatment, close observation of renal function, if the deterioration of renal function, should immediately abort the pregnancy.
