That Silent Kidney Stone Could Become Surgery in 5 Years | Here's Why

A stone that grew from invisible to 18 millimeters started as a scan result nobody followed up on. Here's how to make sure yours doesn't.
Roughly one in twenty CT scans done for something unrelated, like back pain, turns up a kidney stone the patient never felt, and that number keeps climbing as scans get ordered more often. Most silent kidney stones never cause a problem, which is why "just watch it" is common advice. But a long-term UK study found the risk of a silent stone causing pain, blockage, or surgery climbs from about 3% at one year to roughly 19% at three years and 31% at five years. Dr. Sean Hashmi, a board-certified nephrologist, breaks down which silent stones are safe to leave alone, which ones quietly turn into surgery, and what a brand-new 2026 analysis found about treating a stone before it ever causes a symptom.
What you'll learn:

Why stone size and location (upper pole vs. lower pole) predict whether a stone passes on its own
The two strongest warning signs that a silent stone is likely to cause trouble later
What "watching" a stone should actually include, and where ultrasound fits in
Why the flush, juice, and tonic remedies flooding social media can't dissolve a real stone
What a 2026 meta-analysis of six randomized trials found about treating a stone early
