Chapter 4: How Doctors Diagnose and Treat Kidney Stones
When a patient arrives with symptoms suggesting a kidney stone, doctors may use several methods to determine what is happening.
A medical history and physical examination provide the starting point. Doctors may ask where the pain began, whether it has moved, whether there is blood in the urine, and whether the patient has experienced nausea, vomiting, fever, or previous stones.
Urine testing can help identify blood, infection, and other abnormalities. Blood tests may provide information about kidney function and levels of substances associated with stone formation.
Imaging is often particularly important. Depending on the circumstances, healthcare professionals may use ultrasound, X-ray, or computed tomography to identify a stone and determine whether it is causing obstruction.
Treatment depends on factors such as the stone's size and location, symptoms, obstruction, infection, and the patient's overall health.
Small stones may sometimes pass naturally with appropriate medical management. Doctors may recommend pain relief and adequate fluid intake when appropriate, while monitoring the situation.
Larger stones or stones that fail to pass may require a procedure. One commonly used approach is shock wave lithotripsy, which uses focused shock waves to break certain stones into smaller pieces.
Another option is ureteroscopy, in which a small instrument is guided through the urinary tract to locate and remove or fragment the stone.
For particularly large or complicated stones, other surgical procedures may be necessary.
The image provided shows what appears to be multiple stone fragments collected during medical treatment, but the photograph itself cannot establish the exact procedure or diagnosis involved.
The key lesson is that treatment should be determined by medical professionals after evaluating the patient's individual situation.
Trying to force a suspected stone to pass without medical guidance can be inappropriate, particularly if there is an obstruction or infection.
