kidney (renal) stones

Q | what is the treatment for renal stones?

A | Treatment varies according to size and position of the stone within the urinary tract. The size of the stone can range from a small pinhead to the size of a walnut, completely filling the kidney collecting system. Smaller stones may pass spontaneously, however if the stone is too big, intervention may be necessary.

The actual treatment will depend on your clinical history, examination and imaging, usually in the form of X-rays or a CT scan. Nowadays, with the advent of advanced instruments and telescopes, the stone can usually be removed without making any incisions.

Other methods of treating stones include percutaneous nephrolithotomy (PCNL), which is a form of keyhole surgery, or dissolution therapy where the stone can be dissolved by changing the acidity of the urine. In some instances, lithotripsy can be used to shatter the stone using a focused, magnified, sound wave.

Your surgeon will discuss with you the best options for stone removal at your consultation.
