Nephrolithiasis in the early stage can still be pregnant, but during pregnancy may aggravate the progress of kidney disease. In the early stage of nephropathy, we can control the blood pressure and the protein in the urine to less than 0.5 grams after medication, and observe for three months, and if there is no recurrence and aggravation, pregnancy is possible. It is still better for you and your baby. If your condition worsens during pregnancy, or if there is a significant increase in protein in the urine again and again, or even if creatinine and urea have begun to rise, this means that the whole pregnancy has a very big impact on the kidneys. This is the time when we should follow up in time and develop a treatment plan together with the nephrology and obstetrics and gynecology departments. To protect the kidneys, as well as to ensure a safe and smooth delivery of the baby.
