Being diagnosed with a kidney stone can raise questions about the best treatment option. Two procedures commonly used for kidney stones are RIRS (Retrograde Intrarenal Surgery) and PCNL (Percutaneous Nephrolithotomy). However, for a small stone measuring 7 mm, neither procedure is automatically necessary.
The right treatment depends on the stone's location, symptoms, whether it blocks urine flow, and the patient's overall health. Dr. Ankit Gupta provides urological evaluation for patients seeking kidney stone treatment in Gurgaon.
RIRS vs. PCNL: Which Is Better?
RIRS is a minimally invasive procedure in which a flexible instrument is passed through the urinary tract to reach the kidney stone. A laser is then used to break the stone into smaller fragments. It does not usually require an incision in the skin.
PCNL involves creating a small opening through the skin of the back to access and remove kidney stones directly. It is generally used for larger or more complex stones, although selected cases may require a different approach.
For a typical 7 mm kidney stone, PCNL is usually more invasive than necessary. If treatment is required, RIRS may be considered depending on the stone's location and other clinical factors. Some 7 mm stones may also be managed with observation or other treatment options.
Can a 7 mm Kidney Stone Pass Naturally?
Some small kidney stones pass without surgery, but the likelihood depends on their location and whether they have moved into the ureter. A stone that remains in the kidney may not cause symptoms, while one that enters the ureter can cause significant pain.
A urologist may recommend monitoring, medication in selected cases, or a procedure based on imaging results and symptoms. Fever, severe pain, persistent vomiting, or difficulty passing urine requires prompt medical attention.
Consult Dr. Ankit Gupta in Gurgaon
Choosing the right treatment requires an accurate diagnosis rather than relying on stone size alone. Patients searching for the Best Urologist in Gurgaon can consult Dr. Ankit Gupta to discuss kidney stone evaluation and suitable treatment options.
The goal is to select an approach that safely addresses the stone while considering the patient's symptoms, anatomy, and overall kidney health.
Conclusion
For a 7 mm kidney stone, RIRS may be preferable to PCNL when a procedure is needed, because PCNL is generally reserved for larger or more complex stones. However, observation or other treatments may be appropriate in some cases. A urological assessment and imaging review can help determine the best option for each patient.
