Although patients with renal failure are not absolutely unable to become pregnant, pregnancy is ultimately a burden on the kidneys. Pregnant patients with renal failure may experience further deterioration of kidney function and may face numerous complications during pregnancy, such as heart failure, severe anemia, etc., which may pose some risks. However, there are still very rare case reports, including successful pregnancies in patients on dialysis for uremia, but the probability of this is extremely small, and the risks involved are too great. Generally speaking, it is not recommended for female patients with chronic renal failure to become pregnant.
