Although not in all people but kidney
stones in some cases can actually result in a “dead” kidney or kidney failure. The good news though is that this doesn’t happen very often and it often takes a long time to occur.
Thankfully, because most stones are associated with significant amounts of pain, most patients will seek treatment long before permanent damage can occur. However, in cases where patients have “silent” stones ,like you,that cause little or no pain, long term obstruction can occasionally lead to kidney damage.
You must consult your doctor and opt to get it removed .
There are various modes of treatment available like lithotripsy
,per cutaneous nephrolithotomy,open surgery etc.
