Which of the following can cause hematuria?

Hematuria, which is the presence of blood in the urine, can be caused by various factors, with trauma being one of the most direct causes. Trauma may lead to injury of the urinary tract, including damage to the kidneys, bladder, or urethra. Such injuries can cause bleeding that manifests as blood in the urine.

In contrast, while the other options can have significant health implications, they do not typically lead to hematuria in a direct manner. Diabetes Mellitus can cause various complications, but it does not inherently result in blood in urine. Starvation may lead to overall health decline and other metabolic issues, but it is also not a direct cause of hematuria. Anemia, which indicates a deficiency of red cells or hemoglobin in the blood, is associated with other symptoms and conditions but does not directly cause blood to be present in urine.

Thus, trauma stands out as the condition most closely linked with hematuria due to the potential for physical injury to the urinary tract.
