What is the best treatment for pulmonary edema if the person has renal failure?

The person is currently treating it through hemodialysis. Is there any other way to manage it?

Depending on how bad the renal failure is (how high the creatinine runs), small doses of lasix or other diuretics can be given to rid the body of excess fluid.
The dialysis is to treat the kidney failure. It's a tough balancing act for the doctors., and it sounds like "end stage renal disease", which will ultimately (a month, a year, 10 years) likely be the cause of the patients death.
