Question
Why does a newborn have stool but no urine after three days?
Answer
Within the first three days after birth, if a newborn does not urinate, it may be due to renal failure. Renal failure can be categorized into acute and chronic types. Acute renal failure can cause both kidneys to lose excretion function in a short period of time. Early symptoms may include reduced urine output, and in the later stages, dialysis or even kidney transplant surgery may be considered, which are often expensive treatments.
