There can be many causes
for dark urine. These include dehydration
, certain foods, kidney infections,bladder stones or infections, liver disease or hematuria. Presence of blood in urine is called hematuria.Causes include lesions of the urinary tract, contamination during menstruation, disease of the prostate, trauma, tumours, malaria or stones in the urinary tract.
I feel that without clinical examination,pinpointing a diagnosis is tough.
