Hi, Welcome to HealthcareMagic Forum.
is a procedure where surgeon makes a small incision in the back to remove kidney
stones. He/she then puts a hollow tube into the kidney and a probe through the tube. It is done either under, general, regional or spinal anesthesia
. A small catheter inserted into the kidney will drain urine until the kidney heals. You father will be needed to stay in the hospital for 2 to 3 days and take rest for a week. The procedure should take 1 to 2 hours on an average but depneding upon the Doctor's expertise, it can be earlier or later than this.
Since he is Diabetic, there is a risk that his sugars may fluctuate due to stress
and medications. 156 is on the higher side and he needs Insulin
to prevent this. This does not guarantee that he will get addicted to it. He may require Insulin after 10 years of his Diabetic status.
I wish him Good Health, Take Care.
