Kidney Stone Treatment
What Causes Kidney Stones
Kidney stones form when minerals and salts in urine, most often calcium oxalate, crystallize and stick together. Risk factors include dehydration, a diet high in sodium or animal protein, obesity, certain digestive conditions, a family history of stones and some medications. Staying well hydrated is one of the most effective ways to reduce your risk of forming new stones.Signs You May Have a Kidney Stone
Some people have kidney stones without realizing it. Symptoms usually appear once a stone begins moving through the ureter, where it can block the flow of urine. Watch for:- Pain in the abdomen or the side of the back, often sharp and coming in waves
- Burning sensation or pain while urinating
- Increased frequency of urination
- Blood in the urine
- Fever and chills, which can signal an infection
- Nausea and vomiting
How We Diagnose Kidney Stones
Diagnosis typically starts with a review of your symptoms and a physical exam, followed by imaging such as a CT scan or ultrasound to locate the stone and determine its size. A urine test and sometimes bloodwork help identify what the stone is made of, which guides both treatment and prevention.Kidney Stone Treatment Options
Treatment depends on the size, location and composition of the stone as well as your symptoms. Options we may recommend include:
Hydration Therapy
Small stones may pass on their own with increased fluid intake. We provide guidance on how much water to drink and what to watch for while a stone passes.
Medication
Certain medications can help dissolve specific stone types or relax the ureter to help a stone pass more easily. Medication is generally not recommended if you are in severe pain or if the stone is blocking part of the urinary tract.
Extracorporeal Shock Wave Lithotripsy (ESWL)
A non-invasive outpatient procedure in which focused shock waves break the stone into smaller pieces that are easier to pass. You lie on a treatment table while the machine targets the stone from outside the body.
Ureteroscopic Stone Removal
An outpatient procedure using a small scope passed through the urethra and bladder to locate the stone. A laser is often used to break it up before the fragments are removed.
Surgery
In rare or complex cases, surgical removal of the stone directly from the kidney may be necessary. This is generally reserved for very large stones or stones that have not responded to less invasive treatment.
What to Expect After Treatment
Recovery varies by procedure. After ESWL or ureteroscopy, most patients go home the same day, drink plenty of water to help clear residual fragments and may experience mild discomfort or blood in the urine for a few days. A temporary ureteral stent is sometimes placed after ureteroscopy to keep the ureter open while it heals and is removed at a short follow up visit. Your care team will give you written aftercare instructions and a direct number to call with questions. See our patient instructions for general pre and post procedure guidance.Preventing Future Kidney Stones
Once you have had one kidney stone, you are at higher risk of forming another. Common prevention strategies include drinking enough water to keep urine light colored, reducing sodium intake, moderating animal protein and, for some patients, dietary or medication changes based on the composition of your stone. We can build a personalized prevention plan once we know what type of stone you formed.Related Conditions
