Uremia can have low urine output, Uremia is the end stage of chronic renal failure, symptoms include low or no urine output, swelling, fatigue, anemia, elevated blood pressure and other symptoms. Uremia produces low urine volume because uremia patients have lost kidney function, at this time, the function of the kidney to produce urine and excrete urine is lost, so it produces low urine volume or no urine. The treatment at this time is to give hemodialysis or peritoneal dialysis to replace the function of the kidney. We can remove excess water through dialysis treatment to improve the water and sodium retention caused by low urine output, etc. If possible, we can also perform kidney transplantation to cure uremia, and the function of urine will naturally return to normal.
