Pregnant women experience many physical changes owing to the change in levels of hormones. As the body continues to adjust to the developments, there is an increased risk of UTIs. These infections could then go on to cause infections of the kidney or Pyelonephritis.
In simple terms, Pyelonephritis is the infection of the kidney. The infection is usually bacterial. Pyelonephritis can be of two types – acute and subacute, or chronic. Acute pyelonephritis is the sudden and severe onset of an infection of the kidney and is usually seen in pregnant women. This happens due to a range of reasons with the main one being the fluctuation of hormone levels.
Pyelonephritis occurs when an E.coli infection occurs leading to the inflammation of the kidney and pelvis. The infection could occur due to:
During pregnancy, progesterone is released in high volumes, causing the smooth muscles to relax and the uterus to dilate in order to accommodate the growing foetus and placenta. This retards the flow of urine, and in some cases, it stagnates and backs up into the kidney. The kidney then enlarges to allow for the bacteria to multiply and cause an infection.
2. UTI
With the uterus pressing down on the ureter and bladder, the pregnant woman is more susceptible to infections of the urinary tract or UTIs. These infections can then travel up the ureter and infect the kidney.
The signs of pyelonephritis are usually manifest a few days after the infection occurs. The symptoms depend on whether you have acute or subacute pyelonephritis.
2. Subacute Pyelonephritis
The diagnosis of acute pyelonephritis will be done after your doctor takes your full medical history. Some of the methods used for diagnosis that your doctor will recommend include:
Upon a physical exam, if your doctor suspects any problems with the kidneys, then she will ask you to get a urine test done. The test will show up any signs of infection that you may have.
2. Imaging Tests
Imaging tests will be recommended to find if there are any obstructions in the urinary tract that is causing the stagnation and backing up of urine. These tests can determine the presence of cysts or tumours.
3. Blood Test
Your doctor might ask you to get a blood test in order to determine the extent of the infection. Once this is determined, your doctor will be able to develop the ideal treatment plan.
Acute pyelonephritis during pregnancy must be given the right medical attention as soon as possible. If it is left untreated, then the following complications might occur:
If you are diagnosed with acute pyelonephritis during pregnancy, then you will be admitted to the hospital where the first round of treatment is IV antibiotics. If you do not respond to this treatment, then you will be given stronger antibiotics in order to kill the infection.
However, if the infection is caused due to an obstruction such as kidney stones, then the treatment will aim to ease the pressure on the kidneys.
Once you are discharged from the hospital, you will have to continue to take oral antibiotics for ten days. If you develop pyelonephritis during pregnancy then the chances of it reoccurring is quite high. You might be recommended to take a low dosage antibiotic every day for the rest of your pregnancy until the pressure from the uterus eases.
Pyelonephritis needs to be monitored after treatment too. Here is the post-treatment care and monitoring you will need:
After you have been treated for pyelonephritis, your doctor will continue to screen you for any possible reoccurrence of the infection during your regular prenatal routine check-ups. This will include checking on the health of the baby as well as urine tests.
2. After Delivery
Even after delivery, you will have to be screened for the occurrence of the infection of the kidney. While the uterus will no longer be applying pressure on the urinary tract and the hormones would have settled down to the normal levels, there is still a possibility that you will continue to have issues with the kidney depending upon the extent of the initial infection and how soon it was treated.
3. For the Baby
If the pyelonephritis is not treated in a timely manner, the infection could affect the amniotic sac leading to preterm delivery. In such a case, the health of the baby will have to be closely monitored in the initial months in order to ensure that all systems including the immune system are fully developed with no lasting ill effects.
While you do need medical attention to take care of the infection, there are certain home remedies that you can try.
There are many steps you can take in order to avoid a kidney infection during pregnancy. Some of them include:
If you have had UTIs in the past, then you must tell your doctor about it. She will recommend that you get frequent urine tests in order to screen for UTIs during your pregnancy.
Some risk factors include a history of UTI infection, diabetes, and being overweight.
After you are given antibiotics for the infection, you should start to notice signs of relief within three days. However, it is of utmost importance that you continue and complete the entire course of antibiotics in order to fully kill off the infection.
