Hi Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concern...
Most
kidney stones are asymptomatic and are diagnosed coincidentally during an
ultrasound. If a kidney stone is not the cause of pain, it should be let remained there. Slowly over the time the kidney stone get dissolved or get passed through urine.
There are several factors which determine the ability to pass a stone. These include the size of the person, prior stone passage,
prostate enlargement, and the size of the stone.
If stone does not pass or dissolve, Following Treatment would be needed.
1. lithotripsy- a procedure in which ultrasonic
shock waves are used to break stone into smaller ones so that they pass
ureter easily
2.Surgical techniques like laproscopic surgery would be used for stones which do not pass through ureter on their own.
Hope this information helps
