Open Stone Surgery: Comprehensive Nephrolithiasis Treatment

Introduction and Terminology

Open Stone Surgery is a traditional surgical procedure used to treat nephrolithiasis, commonly known as kidney stone disease. Nephrolithiasis occurs when hard mineral deposits, or kidney stones, form within the kidneys, potentially causing pain, urinary tract blockages, and other complications. While many kidney stones can be managed with less invasive treatments—such as shock wave lithotripsy or endoscopic procedures—some cases require a more direct approach. Open Stone Surgery involves making an incision to access and remove kidney stones directly from the kidney or ureter.

Although this procedure is less commonly performed today due to advancements in minimally invasive techniques like percutaneous nephrolithotomy and ureteroscopy, it remains an essential option for complex cases where other nephrolithiasis treatments are ineffective or unsuitable. In the United States, Open Stone Surgery accounts for approximately 1–2% of kidney stone surgeries and is typically reserved for the most challenging cases. Understanding this procedure—including how it differs from less invasive methods—can help patients make informed decisions about their care. The open surgical approach allows surgeons to directly visualize and remove stones that are large, complex, or located in difficult-to-reach areas.

Indications for Open Stone Surgery

Open Stone Surgery may be recommended when other treatments for nephrolithiasis are ineffective or inappropriate. Several specific situations might lead a healthcare provider to suggest this open surgical procedure for kidney stones:

Large or Complex Kidney Stones

Patients with large kidney stones, particularly those exceeding 2 centimeters, may require open surgery. These stones, often referred to as staghorn calculi, can occupy a significant portion of the kidney’s collecting system. If left untreated, large kidney stones can obstruct urine flow and impair kidney function. Open surgery ensures the complete removal of these sizable stones, reducing the risk of recurrence and complications. Minimally invasive methods may not be effective for such large stones due to limitations in instrument size and access.

Stones Resistant to Other Treatments

Some kidney stones, composed of hard materials like cystine or certain types of calcium oxalate, are resistant to fragmentation by shock wave lithotripsy or laser treatments. These stones do not break apart easily, making less invasive treatments ineffective. In such cases, open surgery provides a more reliable solution by physically removing the stones. This approach ensures all stone material is extracted, minimizing the risk of residual fragments that could lead to recurrence.

Multiple Stones in Various Locations

When a patient has multiple kidney stones in different areas of the kidney or urinary tract, open stone surgery may be the preferred option. This approach allows the surgeon to access and remove all stones in a single procedure. Minimally invasive methods might require multiple sessions to address each stone individually, prolonging treatment and recovery times. Open surgery offers a more efficient solution for complex cases of nephrolithiasis.

Anatomical Abnormalities

Structural abnormalities of the kidney or urinary tract can complicate nephrolithiasis management with minimally invasive techniques. Conditions such as horseshoe kidney, ureteral strictures, or congenital anomalies may necessitate an open surgical approach to effectively remove kidney stones and address the underlying issue. Open Stone Surgery allows the surgeon to directly visualize and manage these anatomical variations, improving the likelihood of a successful outcome.

Failed Previous Minimally Invasive Procedures

If prior treatments—such as percutaneous nephrolithotomy or ureteroscopy—fail to remove the kidney stones or result in complications, open stone surgery may be the next recommended step. This approach ensures all remaining stones are removed and reduces the likelihood of further treatment failures. Open surgery provides direct access to the stones and affected areas, allowing for comprehensive management of nephrolithiasis.

Infection-Related Stones

Certain kidney stones, such as struvite stones, are associated with chronic urinary tract infections. These stones can grow rapidly, leading to recurrent infections and other complications. Open surgery allows for thorough removal of infection-related stones and debridement of infected tissue, helping to prevent future episodes. Addressing both the stones and the source of infection is essential for effective treatment.

Obesity or Unfavorable Body Habitus

In some patients, excessive body weight or unique body shapes can limit the feasibility of minimally invasive surgical options. The positioning and instrument reach required for procedures like percutaneous nephrolithotomy may not be possible. Open stone surgery provides better access and visualization, making it a suitable option for these patients. This ensures that kidney stone removal is not compromised by anatomical challenges.

Coexisting Conditions Requiring Open Surgery

When a patient requires open surgery for another condition in the abdominal area—such as abdominal aneurysm repair or tumor removal—combining procedures may be advantageous. This approach reduces the need for multiple surgeries and anesthesia exposures, facilitating comprehensive treatment. Open stone surgery can be performed concurrently, addressing nephrolithiasis while the patient undergoes surgery for another issue.

Non-Functional Kidney Segment

When a portion of the kidney becomes non-functional due to obstruction by stones, open surgery allows the surgeon to remove both the stones and the affected kidney tissue. This can improve overall kidney function and alleviate symptoms. By addressing the damaged areas directly, open stone surgery provides a more definitive solution for managing nephrolithiasis.

Pediatric Patients

In certain pediatric cases, open stone surgery is preferred due to anatomical considerations or when minimally invasive techniques are unsuitable. Children may have different physiological responses, and their smaller anatomy can make less invasive procedures challenging. Open surgery ensures complete removal of kidney stones, providing a safer and more effective treatment option for nephrolithiasis in these instances.

Need for Direct Visualization and Access

Complex cases requiring direct visualization and manipulation of the kidney and surrounding structures may be best managed with open stone surgery. This approach allows the surgeon to address unforeseen issues during the procedure, such as unexpected bleeding or anatomical variations. The ability to see and feel the tissue directly enhances the precision of kidney stone removal.

Patient Preference

After thorough consultation, some patients may prefer open stone surgery over other options. They may value the potential for complete stone removal in a single surgery or have concerns about the effectiveness of less invasive treatments. Understanding the risks and benefits of each approach enables patients to make informed decisions that align with their preferences and lifestyle.

Medical Conditions Contraindicating Minimally Invasive Techniques

Certain medical conditions—such as bleeding disorders, severe cardiopulmonary diseases, or spinal deformities—may make minimally invasive procedures unsuitable. Open stone surgery can be adapted to accommodate these limitations, providing a safer alternative for patients with complex medical histories.

Considering these indications helps patients and healthcare providers determine whether open surgery for kidney stones is the appropriate choice. Evaluating the size, number, and composition of the stones, along with the patient’s overall health and anatomical factors, ensures the chosen treatment aligns with the patient’s needs. Discussing these factors with a urologist can help patients understand their options and what to expect during open stone surgery.

Pre-Operative Preparation

Proper preparation for open stone surgery is essential to ensure the best possible outcome. Here are key steps patients should take before undergoing this surgical treatment for kidney stones:

1. Consultation with Your Doctor: Discuss your medical history, current medications, and any allergies. Your doctor will explain what to expect during open stone surgery and address any questions or concerns.
2. Pre-Operative Testing: Blood tests, urine tests, and imaging studies like CT scans or ultrasounds may be required to assess the size and location of the kidney stones and plan the surgery.
3. Medication Adjustments: Inform your doctor about all medications and supplements you are taking. Certain medications, such as blood thinners (e.g., warfarin, aspirin) and NSAIDs, may need to be paused before surgery to reduce bleeding risks. Your physician will provide guidance on adjustments and when to resume them after surgery.
4. Fasting Instructions: Typically, you will be instructed not to eat or drink after midnight on the day of surgery to prevent complications with anesthesia.
5. Pre-Authorization and Clearances: Ensure all necessary pre-operative clearances and authorizations are obtained, including approval from your primary care provider and insurance company. Our telemedicine primary care practice can assist with pre-operative clearances and ordering pre-op labs and imaging.
6. Arrange Transportation: Plan for someone to drive you to and from the hospital, as you will not be able to drive yourself after the procedure.
7. Work or School Arrangements: Arrange time off from work or school, as recovery time after kidney stone surgery varies based on individual circumstances.
8. Follow Specific Instructions from Your Surgeon: Your surgeon may provide additional instructions, such as showering with antibacterial soap before surgery or avoiding certain products. Follow these instructions carefully.
9. Healthy Lifestyle Practices: Adopt healthy habits leading up to the surgery, such as staying hydrated, eating a balanced diet, and avoiding smoking or alcohol, as advised by your healthcare provider.

By following these steps, patients can ensure they are fully prepared for the procedure. Clear communication with your healthcare team is crucial to address concerns and understand all aspects of the surgery and recovery process. Confirming medication adjustments and adhering to pre-operative instructions can minimize risks and contribute to a smoother experience. If you have questions about preparing for open stone surgery, consult your doctor or our telemedicine primary care practice for assistance.

Procedure Technique for Open Stone Surgery for Nephrolithiasis

Open stone surgery, also referred to as open nephrolithotomy, is a surgical approach used to treat kidney stones that are too large or complex for less invasive methods. Gaining a clear understanding of the procedure can help ease concerns and better prepare you for the experience. This section provides a detailed explanation of the step-by-step process, the roles of the surgical team, the administration of anesthesia, and the expected duration of the operation.

Anesthesia Administration

Before the surgery begins, you will meet with an anesthesiologist, a physician specializing in anesthesia. They will review your medical history, address any questions or concerns, and explain how anesthesia will be administered. General anesthesia is used for open stone surgery, ensuring that you remain unconscious and free of pain throughout the procedure.

An intravenous (IV) line will be placed in a vein in your arm or hand to deliver the anesthesia. Medications administered through the IV will induce sleep, and additional drugs may be provided to help you relax and prevent nausea. During the operation, the anesthesiologist will closely monitor your vital signs, including heart rate, blood pressure, breathing, and oxygen levels, to ensure your safety at all times.

The Surgical Team Roles

A skilled surgical team works collaboratively to perform open stone surgery safely and effectively. The key members of this team include:

1. Urologist (Surgeon): A specialist in urinary tract conditions who performs the kidney stone removal procedure.
2. Anesthesiologist: A physician responsible for administering anesthesia and monitoring your condition throughout the surgery.
3. Surgical Nurses: Registered nurses who assist the surgeon by preparing instruments, maintaining a sterile environment, and providing care before, during, and after the procedure.
4. Surgical Technologist: A professional who prepares the operating room, organizes equipment, and supports the surgeon and nurses during the operation.
5. Radiologic Technologist (if needed): A specialist who operates imaging equipment to provide real-time visuals of the kidney during the procedure.

Step-by-Step Surgical Process

The open stone surgery procedure involves several carefully executed steps, which are outlined below:

1. Patient Positioning

Once anesthesia has taken effect, you will be positioned on the operating table, typically on your side or slightly turned, to give the surgeon optimal access to the kidney. Cushions and supports are used to ensure your comfort and to prevent pressure-related injuries during the procedure.

2. Skin Preparation

The surgical site is thoroughly cleaned with an antiseptic solution to eliminate bacteria and reduce the risk of infection. Sterile drapes are then placed over your body, leaving only the area where the incision will be made exposed.

3. Making the Incision

The surgeon creates an incision in your side or abdomen to access the kidney. The size and location of the incision depend on the position of the kidney stones and your unique anatomy. Typically, the incision is several inches long to provide sufficient visibility and access for the procedure.

4. Accessing the Kidney

Through the incision, the surgeon carefully moves aside muscles, tissues, and, if necessary, organs to reach the kidney. This step is performed with precision to minimize tissue damage. Retractors may be used to hold back tissues and maintain a clear view of the surgical area.

5. Opening the Kidney

Once the kidney is exposed, the surgeon makes a small incision into the renal pelvis, the area where urine collects, to access the kidney stones. If stones are located in other parts of the kidney, an incision may be made directly into the kidney tissue to reach them.

6. Removing the Kidney Stones

The surgeon removes the kidney stones using specialized surgical instruments. For larger or fragmented stones, tools such as forceps or scoops may be used. Intraoperative imaging, such as fluoroscopy or ultrasound, may assist in confirming that all stones have been successfully removed.

7. Inspecting the Kidney and Urinary Tract

After the stones are removed, the surgeon examines the kidney and urinary tract for any remaining stones or abnormalities. This step is essential to address potential issues that could lead to future complications.

8. Closing the Kidney Incision

The incision in the kidney is closed using absorbable sutures, which dissolve over time. This promotes proper healing and reduces the risk of urine leakage.

9. Placing Drains (if necessary)

A small drain may be placed near the kidney to remove any excess fluids, blood, or urine that could accumulate after the surgery. This drain is temporary and is usually removed within a few days.

10. Closing the External Incision

The surgeon closes the muscle and tissue layers with sutures or staples. The skin incision is then sealed with sutures, staples, or surgical glue, and a sterile dressing is applied to protect the area and support healing.

11. Waking Up from Anesthesia

Once the surgery is complete, the anesthesiologist will gradually reduce the anesthesia medications, allowing you to wake up. You will then be moved to the recovery room, where medical staff will monitor your vital signs and ensure your comfort as you regain consciousness.

Duration of the Operation

The length of open stone surgery varies depending on factors such as the size, location, and complexity of the kidney stones, as well as individual anatomical differences. On average, the procedure takes between two to four hours. Your surgeon will provide a more specific estimate based on your unique case.

Post-Procedure Monitoring

After the surgery, you will be closely monitored in the recovery room. The healthcare team will assess your pain levels, vital signs, and the surgical site. Once you are stable, you may be transferred to a hospital room for further observation and recovery.

Understanding the Surgical Treatment for Kidney Stones

Open stone surgery is a comprehensive treatment option for nephrolithiasis, allowing for the direct removal of large or complex kidney stones. By accessing the kidney directly, the surgeon can effectively remove stones that are unsuitable for minimally invasive procedures. While this approach is more invasive, it is sometimes necessary to prevent complications and preserve optimal kidney function.

If you have any concerns or questions, be sure to discuss them with your urologist before the procedure. Understanding what to expect during open stone surgery can help you feel more confident and prepared for recovery. The surgical team is committed to providing safe and effective care to improve your health and well-being.

Post-Operative Recovery from Open Stone Surgery for Nephrolithiasis

Recovering from open stone surgery involves several stages, beginning with your hospital stay. After the procedure, you will be transferred to a recovery room where medical staff will closely monitor your vital signs and manage any discomfort. Pain relief is typically provided through intravenous (IV) medications initially, transitioning to oral medications once you are able to tolerate fluids.

Your surgical team will give you detailed instructions on how to care for your incision to keep the area clean and dry, which helps reduce the risk of infection. In some cases, a drain may be placed near the incision to remove excess fluids; this is usually removed before you are discharged. Most patients are able to leave the hospital within 5 to 7 days, depending on their individual recovery progress.

Once at home, rest is crucial. Strenuous activities should be avoided, although light activities can often be resumed within 2 to 4 weeks. However, heavy lifting and vigorous exercise should be postponed for at least 6 weeks. If your job involves physical labor, you may require additional time off compared to someone with a desk job. Your doctor will provide personalized recommendations based on your occupation and overall health. Regular follow-up appointments will be scheduled to monitor your healing and address any concerns that may arise.

Long-Term Outcomes and Effectiveness of Open Stone Surgery for Nephrolithiasis

Open stone surgery is a highly effective treatment for large or complex kidney stones, particularly when other methods are not suitable. The procedure boasts a success rate of over 90% for completely removing stones, making it a reliable option for managing nephrolithiasis. By directly removing the stones, the surgery not only alleviates symptoms but also improves kidney function.

Several factors can influence the success of the surgery:

1. Patient Health Status: Your overall health, including conditions such as diabetes or hypertension, can impact your recovery. Patients in good health generally recover more quickly and experience better outcomes.
2. Adherence to Post-Operative Guidelines: Following your doctor’s instructions regarding wound care, activity restrictions, and medications is essential for a smooth recovery and to minimize complications.
3. Complexity of the Disease: The size, number, and location of the stones, as well as any anatomical abnormalities, can affect the success of the surgery. More complex cases may require additional interventions.

In some instances, further treatments or therapies may be necessary:

1. Medication Management: To prevent recurrence, your doctor may prescribe medications to regulate the levels of minerals and acids in your urine.
2. Dietary Changes: Adjustments such as increasing fluid intake or reducing foods high in oxalates or sodium can help lower the risk of new stones forming.
3. Additional Surgeries: If stones recur or were not fully removed during the initial procedure, further interventions may be required. Less invasive options, such as shock wave lithotripsy or ureteroscopy, might be considered.
4. Physical Therapy: In rare cases, physical therapy may be recommended to help rebuild muscle strength after prolonged inactivity.

Attending follow-up appointments is vital for monitoring your recovery and kidney health. Imaging tests will confirm that no stones remain and assess your kidney function. Regular communication with your healthcare team allows for early detection and management of any potential complications.

If you experience unusual symptoms such as persistent pain, fever, difficulty urinating, or signs of infection, contact your healthcare provider immediately. Prompt intervention can help prevent serious complications.
