Welcome to HealthcareMagic forum,
Black urine indicates some blood discharge, or sometimes even small black Crystal is just age related. since she was admitted, it is necessary to know for which condition because some drugs even may cause black urine. just wait for few days and it may be solved. otherwise just contact her treating physician. who only may know what medicines she was given.
I hope I answered your query. Wish you good health.

welcome to hcm
thanks for the query
it may be urinary tract infection if it is associated with fever
it mat be normal also due to less intake of fluid
you increase your intake of fluid .if after it the colour remains dark then there may be some pathology there like disorder of kidney or liver
urine may turn dark if she had any injury to any of the structures of the urinary tract, including the kidney, bladder, urethras, or ureter
if it continues after 3 to 4 days consult your doctor
take care
