Knowing how kidney stones move through the urinary tract helps manage pain and complications. We’ll look at the journey of a kidney stone, from forming to passing, and the symptoms people may feel.
Kidney stones form in the kidneys and move down the urinary tract. The journey starts when a stone breaks free from the kidney and enters the ureter. This tube connects the kidney to the bladder.
As the stone moves through the ureter, it can cause a lot of pain. This pain, called renal colic, feels severe and crampy. It can spread from the back or side to the lower abdomen and groin.
The stone’s size and shape affect its journey. Larger stones can cause more pain and may get stuck in narrow parts of the ureter. The ureter’s muscles contract to push the stone down, which is painful.
The time it takes for a stone to pass varies. It depends on the stone’s size, location, and the person’s health. Smaller stones (less than 5 mm) usually pass within a few days to weeks. Larger stones may take longer or need medical help.
People with kidney stones should drink plenty of water and watch their urine. This helps track the stone’s movement. Knowing when symptoms started and when the stone passed is important for doctors.

Kidney stones in the toilet look different based on their type. They vary in composition, each with unique features. Knowing these differences helps you understand what you’ve passed and its health implications.
Calcium oxalate stones are the most common. They look dark brown or black and have rough surfaces. Their jagged shape can cause discomfort. These stones are linked to diet, like high oxalate or low calcium.
Calcium phosphate stones are also common. They are often seen in people with certain metabolic issues. These stones are smoother than calcium oxalate and appear white or light.
Uric acid stones are smooth and round, looking yellow or reddish-brown. They’re more common in those with gout or dehydration. A diet high in animal protein can also lead to their formation.
Struvite stones, or infection stones, are linked to UTIs. They grow quickly and can become large, sometimes without symptoms until they block. These stones are smooth and appear white or gray.
Knowing the type of kidney stone you’ve passed is key to understanding your health. It helps in planning how to prevent future stones. Always consult a healthcare professional for a proper diagnosis and treatment plan.
| Type of Stone | Appearance | Common Causes |
| Calcium Oxalate | Dark brown or black, rough surface | Dietary factors, low calcium intake |
| Calcium Phosphate | White or light-colored, smooth | Metabolic conditions |
| Uric Acid | Yellow or reddish-brown, smooth | Gout, dehydration, high animal protein diet |
| Struvite | White or gray, smooth | Urinary tract infections |
Kidney stones come in different textures, like smooth or jagged. Knowing these textures helps figure out the stone’s type and what might have caused it.
Smooth and round stones form slowly. They are less likely to hurt as they move through the body. Their smooth surface suggests they’ve been there for a while, growing and rounding out.
Jagged stones, on the other hand, are rough and can hurt more. Their sharp edges can irritate the urinary tract, causing pain and possibly bleeding.
Some stones have a crystalline look. This might mean they’re made of calcium oxalate. Their appearance helps doctors diagnose and treat them.
Fragmented stones are broken ones. They can hurt a lot and might need medical help to pass or get removed.
Looking at a stone’s texture helps doctors understand it better. This knowledge is key to treating the stone and preventing more from forming.
Using a strainer to catch kidney stones is a simple yet effective way to aid in their identification. When you pass a kidney stone, catching it can provide valuable information for your healthcare provider.

If you catch a kidney stone, it’s essential to preserve it for medical analysis. You can do this by placing the stone in a clean container filled with water or by following the specific instructions provided by your healthcare provider.
Photographing the kidney stone can also be helpful. Take clear, well-lit photos of the stone from multiple angles. This visual information can be valuable for your healthcare provider.

| Size | Measure the stone’s dimensions in millimeters or inches. |
| Color | Note the stone’s color, which can range from white to dark brown. |
| Shape | Describe the stone’s shape, whether it’s round, irregular, or jagged. |

Men and women have different ways of forming and passing kidney stones. This is due to their body’s structure and how it works. We’ll look at how these differences show up in the look of kidney stones.
Studies show men and women have different types of kidney stones. Men are more likely to get kidney stones than women. But, the stones they get can look different.
Men often get stones that are calcium oxalate. These stones are jagged. Women, on the other hand, tend to get stones that are calcium phosphate or struvite. These stones can look different and feel different too.
Women might notice their kidney stones look different than men’s. Female kidney stones can vary a lot in what they’re made of. This affects how they look.
Women might see stones that are smoother or rounder. This is true for stones made of calcium phosphate or struvite. The color of these stones can also change. They might be white, yellow, brown, or black, depending on what they’re made of.
Men and women have different body parts that can affect how stones pass. The shorter urethra in women can make it easier for stones to move. But, this doesn’t mean there’s no risk of problems.
It’s important to know these differences when treating kidney stones. Doctors need to think about these differences when they’re figuring out how to help patients.
Pregnancy brings special things to think about when it comes to kidney stones. Hormonal changes during pregnancy can make the urinary tract work differently. This might make it more likely for stones to form.
Even though the risk of getting kidney stones during pregnancy isn’t much higher, the changes in the body can make it harder to find and treat stones. Women who get kidney stones while pregnant need careful watching and special treatment plans. This is to keep both the mom and the baby safe.
