Causes include lesions of the urinary
tract, Kidney pathologies, trauma, tumors, malaria or stones in the
urinary tract. In your case UTI needs to be probed thoroughly as to whether it is responsible for causing such symptoms.
I feel that without clinical examination, pinpointing a diagnosis is tough. Also a complete urine examination and culture may be required. Please consult a urologist for confirming the diagnosis.
I hope that helps. Kind regards.
