What Causes Dark Brown Urine After Having Valve Surgery?

My Mom had valve surgery, repaired about 3 weeks ago. She has been back in for several complications or for lack of better words fears. She had papltations which were really fast, we're dealing with those and controlling pressure. Then she had them again, went back to hospital and realized she needed some blood (for a second time) since surgery. She she got 2 units of blood and they gave her a shot in her stomach each day she was there (4 days) to make sure she didn't get any blood clots. She finally returned home and now she has dark brown urine...this has gone on for the last 3-4 days. She had blood taken and urine sample by her doctor, all results were negative. She had a sonogram today..doesn't look like anything abrnormal either. She is scheduled to see a Urologist on the 22nd of this month, of course she is worried. What could this possibly be a result of?

Respected user , hi I evaluated your query thoroughly .
* Valve surgery per se has no relation with dark brown urine after 3 weeks .
* Possibilities are as under :
- urinary infection may be catheter induced
- concentrated urine with altered pH due to various reasons as
dehydration
- certain drugs induced
- DIC ( disseminated intravascular coagulation ) following blood
transfusion
- associated vaginal conditions
- general systemic problem of platelets
- intake of certain beverages
Hope this clears your query.
