Ureteroscopy

Ureteroscopy is a minimally invasive procedure used to diagnose and treat certain conditions affecting the ureter and kidneys. At Houston Methodist, ureteroscopy is typically recommended only when a stone does not appear like it will pass on its own or when other treatment options are not likely to be effective. 

 

Our urology specialists begin with non-surgical treatment whenever possible and recommend a procedure only when more conservative options are unlikely to work or have not provided relief.

 

Houston Methodist urologists perform thousands of procedures each year and use ureteroscopy to treat kidney stones and evaluate other urinary tract conditions with precision and care.

What Is Ureteroscopy?

Ureteroscopy is a minimally invasive procedure in which a thin scope is passed through the urethra and bladder into the ureter or kidney to diagnose or treat conditions such as kidney stones and ureteral abnormalities. The scope may be rigid or flexible, depending on the condition being evaluated or treated.

 

No surgical incisions are required because the scope is passed through the body's natural urinary tract openings.

 

Your doctor considers factors such as stone size, location, symptoms, likelihood of spontaneous passage and the success rate of alternative treatments when determining whether ureteroscopy is the best option.

 

Ureteroscopy is often recommended for stones located in the ureter or kidney that are unlikely to pass naturally, are causing significant symptoms or have not responded to other treatments. Your care team will explain why this approach may be the best option for you.

Types of Ureteroscopy & How They Are Used

Ureteroscopy can be used for both diagnosis and treatment. Depending on your needs, your doctor may use it in one or more of the following ways:

Ureteroscopy with Laser Lithotripsy

If a kidney stone is identified during ureteroscopy, laser lithotripsy is often performed during the same procedure. During this procedure, a laser fiber is passed through the ureteroscope to break the stone into smaller fragments that can be removed or passed naturally.

Stone Extraction

If the stone is small enough, your surgeon may be able to remove it during ureteroscopy using a small wire basket.

Stent Placement

If swelling or blockage is present, a temporary ureteral stent may be placed to help urine drain from the kidney to the bladder while the area heals. Most stents are temporary and are removed after the ureter has healed sufficiently and urine can flow normally.

Tumor Biopsy

Ureteroscopy can also be used to collect a biopsy of suspicious growths or tumors in the ureter or kidney. In some cases, very small growths may also be removed during the same procedure.

How Does Ureteroscopy Work?

Ureteroscopy is performed under general anesthesia or regional anesthesia, so you should not feel pain during the procedure. Your surgeon passes a ureteroscope — a thin instrument with a camera — through the urethra and bladder to reach the ureter or kidney.

 

Once the scope is in place, your surgeon examines the area and treats the problem. This may include removing a stone, breaking up a blockage or collecting tissue for biopsy. Houston Methodist urology specialists use advanced tools and techniques to support precise treatment and clear visualization.

Ureteroscopy Success Rates

Ureteroscopy Success Rates

Ureteroscopy is generally effective, particularly for removing or breaking apart small kidney stones. For many people, success means completely removing the stone or breaking it into pieces small enough to pass without additional treatment.

 

Ureteroscopy has high stone-free rates, particularly for smaller stones. Some patients may require additional treatment if stone fragments remain or if stones are especially large, complex or difficult to access.

 

Ureteroscopy is also effective for diagnosing and treating ureteral abnormalities. Results vary depending on the condition being treated and the complexity of the case. Your doctor will explain the approach most appropriate for your condition and what to expect before and after treatment.

What Conditions Does Ureteroscopy Treat?

Ureteroscopy is used to diagnose and treat a range of conditions affecting the ureter and kidneys, including the following:

Kidney Stones
Kidney stones are hard mineral deposits that form in the kidneys and can cause severe pain, nausea and difficulty urinating. Ureteroscopy — often combined with laser lithotripsy — is commonly used to treat stones that are too large to pass on their own or have not responded to other treatments.

Ureteral Obstructions or Tumors

Obstructions or tumors in the ureter or kidney can block urine flow and may lead to kidney damage if left untreated. Ureteroscopy allows direct visualization, biopsy and, in some cases, treatment of the obstruction. Additional therapies may still be needed depending on the cause.

Ureteral Strictures

A ureteral stricture is a narrowing of the ureter that can block urine flow from the kidney to the bladder. Ureteroscopy allows your surgeon to see the narrowed area and treat it when appropriate.

  • Who Qualifies for Ureteroscopy?

    Your doctor may recommend ureteroscopy if you need treatment or further evaluation for stones, blockages or tumors. It is commonly used when imaging — such as a CT scan or ultrasound — confirms a stone, obstruction or abnormality that requires treatment or direct evaluation.

     

    To determine whether ureteroscopy is right for you, your care team will review the size, location and characteristics of the stone or abnormality, along with your anatomy and overall health. They will also explain any alternatives and why one approach may be a better fit than another.

  • Preparing for Ureteroscopy

    Preparation begins before the procedure. Follow your surgeon’s instructions carefully to support safe surgery and a smoother recovery. Your doctor may recommend steps such as:

     

    • Completing any required pre-op lab work or imaging
    • Stopping blood-thinning medications if your doctor advises it
    • Stopping smoking, vaping or using other tobacco products before surgery
    • Arranging transportation and support at home
    • Setting up a comfortable recovery space at home
    • Following any antibiotic instructions if your doctor prescribes them
    • Stopping eating or drinking when instructed the night before the procedure

     

    These steps can help support a safer procedure, smoother recovery and a lower risk of infection or bleeding.

  • Recovering From Ureteroscopy

    Ureteroscopy is minimally invasive, and many people go home the same day. Recovery depends on the procedure performed, the size and location of the stone and whether a temporary stent is placed.

     

    During the first day or two after the procedure, you may feel tired as the anesthesia wears off. It is also common to notice burning with urination or increased urinary frequency during this time.

     

    Mild discomfort, urinary symptoms and light blood in the urine are common during recovery, particularly if a stent has been placed. If your job is mostly sedentary, you may be able to return to work after a few days. Physically demanding work may require a longer recovery period.

     

    Your surgeon may place a temporary ureteral stent to support healing and urine drainage. While a stent is temporary, some people notice urinary urgency, frequency or mild discomfort while it is in place. These symptoms typically improve once the stent is removed. Your care team will explain what to expect and when the stent will be taken out.

     

    While stent-related discomfort is common, it is usually manageable with medication. Staying well-hydrated, moving gently as advised and keeping follow-up appointments are important parts of recovery.

     

    Mild symptoms are common after ureteroscopy but contact your care team if symptoms feel worse instead of gradually improving. You should also seek medical attention if you have a fever, severe or worsening pain, heavy bleeding or difficulty urinating. Your doctor will explain which symptoms are expected and which may require follow-up.
