Is a 6mm Kidney Stone Serious?

A 6mm kidney stone is typically not considered large and often does not cause any noticeable symptoms. If there is no associated pain, bleeding, or infection, immediate medical intervention may not be necessary. In many cases, the stone can pass naturally through the urinary tract with adequate hydration, regular physical activity, and dietary adjustments.

However, if the stone causes complications such as obstruction, hydronephrosis (swelling of the kidney due to urine buildup), recurring pain, infection, or persistent bleeding, treatment should be considered. In such cases, extracorporeal shock wave lithotripsy (ESWL) is usually the first-line treatment. This is a minimally invasive procedure that uses shock waves to break the stone into smaller pieces, allowing them to pass more easily through the urinary system.

If ESWL is not effective or not suitable, ureteroscopy may be recommended. Ureteroscopy involves using a small scope inserted through the urethra and bladder into the ureter or kidney to locate and remove or break up the stone. There are two types of ureteroscopes: rigid and flexible. For stones located in the upper ureter or renal pelvis, a flexible ureteroscope is often used. On the other hand, if the stone has moved into the mid or lower ureter, a rigid ureteroscope is typically preferred.

During the procedure, a holmium laser is often used to fragment the stone into smaller pieces, which can then either be removed or passed naturally. This method is highly effective and avoids the need for open surgery. It is important to consult with a urologist to determine the most appropriate treatment based on the stone's location, composition, and your overall health condition.
