RIRS Vs URSL | Methods For Kidney Stone Treatment

RIRS (Retrograde Intrarenal Surgery) uses a flexible ureteroscope to remove kidney stones, while URSL (Ureteroscopic Lithotripsy) uses a rigid or semi-rigid ureteroscope to break up stones in the ureter. Knowing the difference is crucial for selecting the most effective and least invasive treatment based on stone location and size. While this page will provide you with significant information related to both procedures, it is also important that you speak to our expert urologists to make the correct treatment decision.

What Happens in RIRS?

RIRS, or Retrograde Intrarenal Surgery, is a modern method used to treat kidney stones. During the procedure, a doctor will guide a flexible ureteroscope, a thin viewing instrument, through your urethra (the tube that carries urine out of your body), bladder and then into your ureter (the tube connecting your kidney and bladder). The ureteroscope has a light and camera on its tip, allowing the doctor to look for kidney stones.

Once the stone is located, it is broken into tiny pieces using a laser. These pieces can then be easily passed out of the body through urine. Since this procedure does not involve any cuts or incisions, it’s less painful than other treatments, and recovery time is quicker.

What Happens in URSL?

Ureteroscopic lithotripsy (URSL) is another effective treatment for kidney stones. It involves using a similar instrument as in RIRS, called a ureteroscope, to locate the stone. This time, however, the stone is destroyed using shock waves rather than a laser.

These shock waves, produced by a device called a lithotripter, create strong vibrations that crush the stone into small parts. These pieces are small enough to be passed out of the body through urine. Just like RIRS, URSL is also minimally invasive.

Are you going through any of these symptoms?

When is RIRS done?

RIRS is generally advised when the size of the kidney stone is less than 1.5 centimetres. However, it can be used to treat larger stones as well in some cases. The decision on whether RIRS or URSL is more suitable depends on various factors, such as the size, location and composition of the stone, as well as your overall health.

The doctor will make this decision after examining you and conducting the necessary tests. You may also discuss it with your doctor if you have any preferences based on your comfort level and understanding of the procedures.

Remember, it’s essential to follow your doctor’s advice for a successful and smooth recovery. Don’t hesitate to ask them any questions you may have about these procedures. They’re there to help you through every step of your healthcare journey.

When is URSL done?

You might be advised to undergo URSL if you have a kidney stone that is too large to pass naturally, typically more than 4 mm in diameter. Similarly, if the stone is causing severe pain, infection, or blocking urine flow, your doctor may recommend URSL. In this procedure, a thin viewing instrument (ureteroscope) is used to locate the stones, which are then broken down into smaller fragments using laser energy. These pieces can then be easily passed out of the body through urine.

Benefits of RIRS

RIRS is an effective technique for managing kidney stones. It offers many benefits, which include:

  • Minimal invasion: Unlike other surgical procedures, RIRS does not involve any cuts or incisions on the body.
  • Less pain: As it’s less invasive, the pain experienced post-operation tends to be considerably less in comparison to other procedures.
  • Shorter hospital stay: Patients generally can leave the hospital within a day after the procedure.
  • Lower risk of complications: The chances of infection or bleeding are reduced due to the minimal invasion.

It’s also worth mentioning that RIRS allows doctors to treat stones located anywhere in the kidney with precision and effectiveness.

Benefits of URSL

URSL also comes with its own set of benefits. Let’s take a closer look:

  • Higher success rate: URSL has a high success rate in removing stones from the ureter, especially lower ureteric stones.
  • Faster recovery: Patients often recover faster after URSL compared to open surgery.
  • Less traumatic: No incisions mean less pain and less scarring.
  • Short hospital stay: Similar to RIRS, patients undergoing URSL also usually require a short hospital stay.

Through the comparison of RIRS and URSL, it’s evident that both procedures have their own unique advantages. Your doctor will recommend the right treatment based on your specific condition and the characteristics of the kidney stones.

Risks of RIRS

While it has its advantages, like any medical procedure, RIRS comes with its share of risks. The most common complications you may face include:

  • Bleeding: Although rare, there can be slight bleeding post-surgery. Always keep your doctor informed about any blood in your urine.
  • Infection: There’s a small chance of developing an infection after the operation. Typically, antibiotics are given to prevent this.
  • Damage to the ureter: On rare occasions, the equipment used may cause minor damage to the ureter.

Understanding these risks can help you make an informed decision about your treatment options.

Risks of URSL

URSL is another technique used to treat kidney stones. URSL also has potential risks, including:

  • Ureteral injury: The ureter might get injured during the procedure, but this is quite rare.
  • Infection: Post-operative infection can happen, and preventive antibiotics are typically administered to mitigate this risk.
  • Stricture or narrowing of the ureter: Over time, scarring from the operation might lead to narrowing of the ureter, affecting urine flow.

Having a talk with your family doctor about these risks will allow you to weigh your options and pursue the best course of action for your health.

Recovery after RIRS

Once you’ve undergone RIRS, it’s important to know what to expect during recovery. Here are some key points:

  • Pain management: After surgery, you may feel some discomfort. Painkillers prescribed by your doctor should help you manage this.
  • Rest and recuperation: You’ll need to rest for a few days post-procedure. Remember not to rush your recovery.
  • Regular follow-ups: It’s crucial to stick to your follow-up schedule with your doctor. This allows your doctor to monitor your recovery and address any potential complications early on.

Remember, each person’s recovery is unique. It’s important to tune into your body and communicate openly with your doctor about what you’re experiencing during the recovery phase.

Recovery After URSL

Recovery post-URSL is generally swift, with most patients being discharged from the hospital on the same day. However, there might be some discomfort, like blood in urine or frequent urge to urinate, for a few days following the procedure.

  • Drink plenty of fluids to help pass the stone fragments.
  • Over-the-counter pain medications may be used as per your doctor’s advice.
  • Regular follow-ups with your doctor are essential to ensuring complete stone removal and preventing recurrence.

Comparison Between RIRS and URSL

Understanding the key differences between RIRS and URSL can help you make the right choice depending on your specific healthcare needs. Let’s get started.

Criteria RIRS (Retrograde Intrarenal Surgery) URSL (Ureteroscopic Lithotripsy)
Procedure In this procedure, a flexible ureteroscope is passed through the urethra and bladder to reach the kidney. The stones are then directly visualised and fragmented using a laser. This involves passing a thin, rigid instrument known as a ureteroscope through the urethra and bladder to reach the ureter, where the stones are broken down by a laser.
Cuts or Incisions This is performed without any incisions, hence, it’s often referred to as a minimally invasive procedure. Similar to RIRS, this procedure also doesn’t require any incisions.
Surgery Duration The average duration for this type of surgery is between 1 to 3 hours. Typically, URSL surgeries can be completed in about 1 to 2 hours.
Recovery Patients can typically return home the same day, with full recovery taking around one week. Patients are usually discharged on the same day but may take slightly longer, around two weeks, to fully recover.
Cost While the cost can vary depending on various factors, on average, it is slightly higher than URSL due to the specialised equipment used. Generally, URSL is less expensive compared to RIRS.
Success Rate The success rate of RIRS is very high, often exceeding 90%, especially for smaller stones. The success rate of URSL is also high, but slightly lower than RIRS for larger stones.

 

It’s always best to consult with your family doctor or a urologist before making any decisions. They will be able to advise you on the best treatment option based on your individual health condition and lifestyle needs.

Frequently Asked Questions

Is RIRS surgery painful?

RIRS surgery is generally not very painful, as it is performed under anesthesia. Patients may experience mild discomfort or soreness after the procedure, which can typically be managed with pain medication.

Which is better? - RIRS or URSL?

Both RIRS and URSL have their pros and cons; RIRS is less invasive and better for kidney stones, while URSL is effective for stones in the ureter. The best treatment depends on individual factors, and the doctor will decide based on the stone’s location, size, and the patient’s overall health.

Is DJ stenting used in URSL?

Yes, DJ (Double J) stenting is often used in URSL to ensure proper drainage of urine, prevent ureteral obstruction, and facilitate healing after the procedure.

When can I go home after RIRS?

Patients can usually go home the same day or the day after RIRS, depending on their recovery and the doctor’s assessment.

When can you home after URSL?

Patients can typically go home the same day or within 24 hours after URSL, depending on their recovery and the doctor’s evaluation.
