Kidney Stones – Everything You Need to Know

When working with kidney stones, hard mineral deposits that form in the kidneys and can cause severe pain when they move through the urinary tract. Also known as renal calculi, they affect millions each year. One common subtype is calcium oxalate stones, stones made mostly of calcium combined with oxalate, the most frequent type found in adults. A popular non‑invasive treatment is shock wave lithotripsy, a procedure that uses focused sound waves to break stones into passable fragments, while uric acid stones, formed from high purine metabolism, often respond to dietary changes and medication.

Most kidney stones develop because of an imbalance between substances that promote crystal formation and those that keep them dissolved. High concentrations of calcium, oxalate, uric acid, or cystine in the urine are the usual suspects. Dehydration tops the list of lifestyle factors – when you drink less, urine becomes more concentrated, making it easier for crystals to stick together. Diets rich in sodium, animal protein, or excessive vitamin C can also push the chemistry toward stone formation. Understanding kidney stones helps you spot the hidden triggers before they turn into a painful episode.

Symptoms usually appear once a stone starts moving. A sudden, sharp flank pain that radiates to the groin, blood in the urine, nausea, and frequent urges to urinate are classic signs. If the stone is small, the body may pass it on its own, and increasing fluid intake speeds the process. Larger stones, however, often need medical help. Imaging tests such as a non‑contrast CT scan or an ultrasound quickly confirm the stone’s size, location, and composition, guiding the choice of treatment.

When it comes to treatment, the size and type of stone dictate the approach. Stones under 5 mm often pass with hydration, pain relief, and a short course of alpha‑blockers to relax the ureter. For stones between 5‑10 mm, shock wave lithotripsy is the first‑line option in many centers because it avoids incisions. Stones larger than 10 mm, or those stuck in difficult locations, may require ureteroscopy (a tiny scope threaded up the urinary tract) or percutaneous nephrolithotomy, where a small incision lets the surgeon remove the stone directly. Each method aims to break the stone into fragments small enough to exit the body without causing further injury.
