Hello and welcome to HCM.
Thank you for your query.
First of all I respect you for caring so much for your mother and taking care of her, it is really difficult to find individuals like you in today's world.
Now coming to your query and the advice I have to offer. You need to understand that we first need to find the cause, and only then initiate treatment. To find the cause we need some cost-effective and accurate investigations. So let us come to that one by one, okay?
Starting with the current most troubling thing, which is the burning sensation while urinating and blood in the urine. These are clear indications of a possible
urinary tract infection. We will need to conduct a urine analysis and a urine culture examination for this. These 2 investigations will confirm the infection and due to your mother's age, she might be resistant to many antibiotics, which is why I have advised the urine culture examination, this will provide information on the best medicine that can be used to treat her infection.
Now coming to the next aspect, your mother is a diabetic. Urinary tract infections are very common in diabetics, and so you will have to ensure and constantly monitor her blood sugar levels. You will HAVE to maintain a good blood sugar level, and keep it under control, or else the infections will recur/return.
Finally coming to the conclusion drawn by another doctor about a stone in the renal system, I would advice an
ultrasound of the abdomen and pelvis to confirm this. Only if it is detected you need to worry about it, if not, it might either be absent or too small to cause any problems. You can then ignore it.
For now and the future, give your mother plenty of fluids. She might urinate more often, but this will help in expelling any small stone(s) present in her renal tract and prevent the stagnation of urine in her renal tract that can result in infections.
I hope I have succeeded in providing the information you were looking for. Please feel free to write back to me for any further clarifications. I would gladly help you.
Best wishes.
