The majority of stones pass spontaneously within 48 hours. If a symptomatic stone does not pass, a procedure by a urologist may be needed. Nephrolithiasis is derived from the Greek nephros- (kidney) lithos (stone) = kidney stone.
Percutaneous nephrolithotomy (tunnel surgery). A surgical procedure for stones that cannot be treated with lithotripsy or endoscopic procedures. It involves the removal of a stone through a thin tube tunneled through a small incision in the back into the kidney.he shock waves break a large stone into smaller stones that will pass through the urinary system.
