Ureteroscopy is a modern urological procedure used to examine and treat problems in the urinary tract, particularly in the ureters the tubes that carry urine from the kidneys to the bladder. Whether you’re facing persistent kidney stones or unexplained urinary issues, your urologist may recommend a ureteroscopy for diagnosis and treatment.
In the past, open surgery was the primary option for treating conditions inside the ureter, often resulting in longer recovery times and higher risks. However, ureteroscopy revolutionized urological care by allowing urologists to access the ureters and kidneys through a natural opening the urethra using a thin, flexible or rigid instrument known as a ureteroscope.
What is Ureteroscopy?
Ureteroscopy (URS) is a minimally invasive procedure that allows doctors to view and treat conditions inside the urinary tract using a thin, flexible or rigid scope called a ureteroscope. This scope is inserted through the urethra and bladder, and then advanced into the ureter and even the kidney, if necessary. The tool includes a tiny camera and a light source, which help the urologist visually examine the urinary tract in real-time.
The procedure is commonly used for diagnosing and treating conditions such as kidney stones, strictures (narrowing of the ureter), tumors, and unexplained bleeding. Unlike some other procedures, ureteroscopy does not require any external incisions, making it a relatively safe and less invasive option for many patients.
When is Ureteroscopy Recommended?
Doctors often recommend ureteroscopy when non-invasive imaging tests like ultrasounds or CT scans show abnormalities in the urinary tract. The most common reasons for a ureteroscopy include :-
-
Kidney Stones :- To locate and remove or break up stones that are stuck in the ureter or kidney.
-
Unexplained Hematuria :- To find the cause of blood in the urine.
-
Suspected Tumors or Growths :- For direct visualization and biopsy of any abnormal tissues.
-
Ureteral Strictures :- To diagnose and sometimes treat narrowed areas in the ureter.
Types of Ureteroscopes
There are two main types of ureteroscopes used depending on the purpose of the procedure :-
-
Rigid Ureteroscope :- Used primarily for stones in the lower ureter. This type is less flexible but highly effective in straightforward cases.
-
Flexible Ureteroscope :- Ideal for accessing the upper ureter or kidney. Its flexible nature allows it to reach more challenging areas.
The choice between the two depends on the stone location, suspected condition, and the anatomy of the patient’s urinary tract.
The Ureteroscopy Procedure: Step by Step
Ureteroscopy is typically performed under general or spinal anesthesia, ensuring that the patient feels no pain during the procedure.
-
Preparation :- Patients are advised not to eat or drink for several hours before the procedure. Blood tests and imaging might be conducted in advance.
-
Insertion of the Ureteroscope :- The doctor inserts the ureteroscope through the urethra into the bladder and then into the ureter.
-
Examination and Treatment :- If kidney stones are present, they may be removed using tiny instruments or broken up using a laser (laser lithotripsy). Any suspicious tissue can be biopsied.
-
Stent Placement (if needed) :- In some cases, a temporary ureteral stent is placed to keep the ureter open and allow healing. This is usually removed after a few days or weeks.
-
Completion :- Once the examination and treatment are complete, the ureteroscope is withdrawn. The patient is moved to a recovery area for monitoring.
Benefits of Ureteroscopy
Ureteroscopy offers several benefits, especially when compared to traditional surgical techniques :-
-
Minimally Invasive :- No cuts or incisions on the skin.
-
High Success Rate :- Especially effective in removing stones and taking accurate biopsies.
-
Quick Recovery :- Most patients can return home the same day or after an overnight observation.
-
Precision :- Direct visualization allows targeted treatment of small abnormalities.
Potential Risks and Complications
Like all medical procedures, ureteroscopy has some risks, although serious complications are rare. Possible risks include :-
-
Temporary discomfort or burning sensation while urinating.
-
Blood in urine for a few days post-procedure.
-
Infection of the urinary tract.
-
Ureteral injury or narrowing (stricture) in rare cases.
-
Need for additional procedures if stones are not completely removed.
Your urologist will discuss these risks and answer any questions you may have before the procedure.
Post Procedure Recovery and Aftercare
Recovery after ureteroscopy is usually swift. Patients can expect some mild discomfort and blood tinged urine for 24 to 72 hours. Drinking plenty of water helps flush out the urinary tract and aids healing.
If a stent has been placed, you may feel a frequent urge to urinate or mild bladder discomfort. These symptoms improve after the stent is removed. Your doctor will schedule a follow-up appointment to remove the stent and assess your recovery.
In most cases, patients can resume daily activities within a day or two. However, strenuous physical activities and lifting heavy objects should be avoided for at least a week.
Tips for Smooth Recovery
-
Stay hydrated with water and avoid caffeine or alcohol for a few days.
-
Take prescribed pain medications or antibiotics as directed.
-
Avoid heavy lifting or intense workouts for at least 5–7 days.
-
Inform your doctor if you experience fever, chills, or worsening pain, which may indicate infection.
Ureteroscopy vs. Other Stone Removal Techniques
When it comes to treating kidney or ureteral stones, ureteroscopy is just one option. Others include shock wave lithotripsy (SWL) and percutaneous nephrolithotomy (PCNL). Ureteroscopy is often preferred for mid to lower ureteral stones or when other methods have failed.
Its advantage lies in the precision and ability to treat even small or hard to reach stones. However, for larger stones in the kidney, PCNL may be more appropriate.
Conclusion
Ureteroscopy is a safe, effective, and minimally invasive way to diagnose and treat various urinary tract conditions, particularly kidney and ureteral stones. With modern technology, recovery is fast, and the success rate is high, making it a go-to option for urologists worldwide.
