For newborns with little urine, parents can use the following treatment methods: 1, increase the amount of milk, if the intake of milk is relatively small, there will be a very small amount of urine, which is the most common cause of the small amount of urine. After increasing the amount of milk, the volume of urine will naturally be increased; 2, caused by renal failure, if suffering from a serious disease, if there is septic shock, etc.. In this case there are often complications of acute renal failure, and if there are serious kidney stones, it can also cause the appearance of oliguria. Parents should treat the newborn in time for acute renal failure as well as the treatment of stones. After the urinary stones and renal failure have been corrected, the amount of urine will naturally increase, which is a relatively rare occurrence, and parents must observe it in time.
