When Is Kidney Stone Surgery Necessary?

Kidney stones are a medical condition that can cause severe pain. The discomfort experienced by people passing kidney stones can sometimes significantly affect their daily lives. However, not every case of kidney stones requires surgery. The location, size, and shape of the stone are the most important factors in determining the appropriate treatment method. Stones can be located inside the kidney, in the ureter—the tube that carries urine from the kidney to the bladder—or in the bladder. Some stones may pass spontaneously by increasing fluid intake, staying physically active, and taking medications prescribed by a doctor. Stones smaller than 5 mm, particularly those located in the ureter, have a high likelihood of passing on their own. Therefore, for suitable patients, monitoring and medication may be preferred over immediate surgery. However, even a small stone should not be left untreated if it causes kidney damage, obstructs urine flow, or leads to an infection. When a stone does not damage the kidney or cause significant obstruction or infection, it may be monitored through regular follow-up appointments. Ultrasound and other imaging methods, when necessary, are used during this process. On the other hand, surgical treatment may be considered when a stone causes severe pain, bleeding, infection, or impaired kidney function. Thanks to advances in medical technology, some stones that were previously managed only through observation can now also be treated using appropriate minimally invasive surgical techniques. In conclusion, not every kidney stone requires surgery. The treatment decision should be made by a urologist after evaluating the characteristics of the stone and the patient's overall health.
