Kidney Stones in Gwalior: Why They Keep Coming Back and What to Do About It

Anyone who has had a kidney stone describes the pain in dramatic terms. And they are not exaggerating. Renal colic, the pain caused by a stone moving through the urinary tract, is one of the most intense acute pains a person can experience. What is less well known is why stones form in the first place, and more importantly, what reduces the risk of them coming back.

Why Kidney Stones Form

Stones form when the concentration of certain minerals in the urine becomes high enough that they crystallise and clump together. The most common type, calcium oxalate stones, form when calcium and oxalate levels in the urine are elevated. This can happen due to dehydration (concentrated urine), a diet high in oxalate-rich foods, underlying metabolic conditions, recurrent urinary tract infections, or certain medications. Gwalior’s hot climate is a factor too. When people do not drink enough fluid in hot weather, urine becomes more concentrated, and stone risk rises.

Stones That Pass on Their Own vs. Stones That Need Help

Many kidney stones are small enough to pass through the urinary tract naturally with adequate fluid intake and pain management. Stones smaller than 5mm pass spontaneously in the majority of cases. Stones between 5 and 10mm pass in roughly half of cases. Stones larger than 10mm rarely pass on their own and almost always require intervention. The location of the stone also matters. Stones in the lower ureter (closer to the bladder) have a higher spontaneous passage rate than stones in the upper ureter or kidney.

When Surgery or Intervention Is Needed

Intervention is recommended when a stone is too large to pass naturally, when it is causing an obstruction that is damaging the kidney, when there is an associated infection, or when the pain cannot be controlled. The main interventional options are ESWL (Extracorporeal Shock Wave Lithotripsy), which uses sound waves to break the stone from outside the body; URS (Ureteroscopy with Laser Lithotripsy), which involves passing a thin camera up the ureter to the stone and using a laser to break it; and PCNL (Percutaneous Nephrolithotomy), used for large or complex stones inside the kidney. At Kalyan Hospital, Gwalior, we perform all of these procedures.

The Diet Connection: What to Eat and What to Avoid

Diet has a real impact on kidney stone recurrence. Staying well hydrated is the single most important preventive measure, aiming for clear to pale yellow urine throughout the day. For calcium oxalate stones (the most common type), reducing intake of oxalate-rich foods such as spinach, nuts, chocolate, and tea is helpful. Contrary to popular belief, reducing calcium intake is not recommended, as adequate dietary calcium actually helps bind oxalate in the gut and reduces its absorption. Reducing salt and animal protein also lowers stone risk.

Why Stone-Formers Need Metabolic Evaluation

If you have had more than one kidney stone, or if your first stone was large or bilateral, a metabolic evaluation is worthwhile. This involves 24-hour urine collection to analyse what exactly is in your urine in excess, blood tests to check calcium and uric acid levels, and in some cases imaging to assess the kidneys. The results guide specific dietary and medication recommendations that meaningfully reduce the chance of future stones. At Kalyan Hospital, Gwalior, this evaluation is available and recommended to any patient with recurrent stone disease.
