Hello, I'm Dr. Smith, a urologist specializing in the diagnosis and treatment of kidney stones. It's a common problem, and I'm happy to discuss it with you.

Passing a 7 millimeter kidney stone can be quite a challenge, and the likelihood of success depends on several factors. Here's a breakdown of what you need to know:

Size: A 7mm stone is considered large, and the chances of passing it naturally are lower than with smaller stones.

Location: The location of the stone within the urinary tract plays a crucial role. Stones located in the lower ureter (the tube connecting the kidney to the bladder) are more likely to pass than those in the upper ureter.

Shape: The shape of the stone can also impact passability.
Smooth, round stones have a better chance of passing than jagged or irregular stones.

Other Factors: Your overall health, pain tolerance, and the presence of any underlying conditions can all influence the outcome.

Treatment Options:


1. Conservative Management: This approach involves pain management, increased fluid intake, and possibly medications to help relax the ureter and facilitate stone passage. It's often the first line of treatment for smaller stones, but for a 7mm stone, the success rate is significantly lower.

2. **Extracorporeal Shock Wave Lithotripsy (ESWL):** This procedure uses shock waves to break up the stone into smaller fragments that are easier to pass. It's a non-invasive option, but it may not be effective for all stones.


3. Ureteroscopy: This procedure involves inserting a thin, flexible scope into the ureter to remove the stone. It's a minimally invasive procedure that can be done under anesthesia.


4. Percutaneous Nephrolithotomy (PNL): This involves making a small incision in the back to access the kidney and remove the stone. It's a more invasive procedure, but it's often the most effective option for larger stones.

What to Do Next:

If you are experiencing symptoms related to a 7mm kidney stone, it's crucial to seek medical attention immediately. A urologist can assess your specific situation, recommend the most appropriate treatment plan, and guide you through the process.

Remember, your health is paramount. Don't hesitate to reach out to a medical professional if you have any concerns.
