This condition may be due to the presence of cardiac insufficiency or renal insufficiency in the patient, and accordingly there will be a decrease in urine output as well as edema. It is recommended that patients can check renal function, urological ultrasound, cardiac ultrasound, NT-proBNP, etc. to further clarify the diagnosis. If the decrease in urine output and edema is caused by kidney failure, it needs to be combined with hemodialysis treatment if necessary. If the decrease in urine output and edema is caused by heart failure, it can be improved by combining with static pushing of Torasemide.
