How to Determine if a Kidney Stone Has Moved into the Bladder

When a kidney stone moves into the bladder, patients often experience a shift in symptoms. Initially, the pain may be localized in the flank or lower back, but as the stone progresses into the bladder, it typically causes increased urinary frequency, urgency, and discomfort or pain during urination. These changes in symptoms can serve as early indicators that the stone has moved, although they are not sufficient for a definitive diagnosis.

To accurately confirm whether a stone has entered the bladder, medical imaging is essential. Diagnostic tools such as ultrasound, X-ray, or CT scans are commonly used to visualize the stone's location. In particular, an ultrasound can provide real-time imaging, allowing doctors to observe the stone moving within the bladder.

Once it is confirmed that the stone has reached the bladder, the treatment approach depends largely on the size of the stone. For stones smaller than 5 millimeters, doctors often recommend increased fluid intake to help naturally expel the stone. Larger stones may require medical intervention such as cystoscopy or lithotripsy to break up or remove the stone safely.

In summary, while symptom changes can suggest that a kidney stone has moved into the bladder, only imaging tests can provide a clear diagnosis. If you suspect a stone has moved, consult a healthcare professional to determine the best course of action based on the stone's size and your overall health.
