What are Ureteral Stones?
Ureteric stones are hard mineral crystals that form in the ureters, which carry urine from the kidneys to the bladder. These stones usually form in the kidneys and move into the ureters with the flow of urine. The ureters are thin tubes that carry urine between the kidneys and bladder, and this is where stones can get stuck.
Ureteric stone treatment varies depending on the size, location, and symptoms of the stone. Here are the main methods used to treat ureteral stones:
1. Medical Management
Small stones can usually pass on their own. During this process, doctors usually recommend the following treatments:
- Pain Management: NSAIDs (nonsteroidal anti-inflammatory drugs) or opiates can help relieve severe pain during stone passage.
- Plenty of Fluid Consumption:Drinking 2-3 liters of water a day can help the stone pass more easily through urine.
- Alpha Blockers:Drugs such as amsulosin can relax the muscles of the ureter, making it easier for stones to pass and reducing pain.
2. Shock Wave Lithotripsy (ESWL)
This method uses high-energy acoustic waves to break up the stone into smaller pieces so that it can be more easily passed in the urine. ESWL is an effective option, especially for stones smaller than 10 mm. This topic is covered in more detail in Kidney Stone Treatment.
3. Ureteroscopy
Ureteroscopy is a minimally invasive surgical procedure used to directly visualize and remove stones in the ureter. This method is especially preferred for removing ureteral stones because it provides direct access to the stone and can break up and remove the stone in situ.
Ureteroscopy is usually performed under local, spinal, or general anesthesia. The urologist passes a thin, flexible tube called a ureteroscope through the patient's urethra, passing through the bladder and then the ureter. The ureteroscope has both a camera and channels that hold various instruments to remove or break up stones.
After the stones are directly visualized, they can be pulled out with special instruments if their size is appropriate. Larger stones are usually broken up using energy sources such as lasers. The fragmented small pieces of stone are either expelled naturally or removed with surgical instruments.
Advantages:
- Direct Access:Ureteroscopy provides direct access to the stone, which leads to high success rates.
- Rapid Recovery:Because it is a minimally invasive procedure, patients can usually return to their normal activities shortly after the procedure.
- Flexibility:Regardless of the size and location of the stone, ureteroscopy can be performed in most cases.
Risks:
- Ureteral Damage: Rarely, damage to the ureter may occur, which may require repair.
- Infection: As with any surgical procedure, there is a risk of infection after ureteroscopy.
- Stone Fragments Remain: If all fragmented stones cannot be removed, recurrent stone formation is possible.
After ureteroscopy, patients are usually monitored for several weeks. After the procedure, there may be bloody urine, mild pain or cramping, but these symptoms usually subside in a short time. Patients are advised to drink plenty of fluids and, in some cases, antibiotic treatment may be recommended. It is important for patients to consult their doctor immediately if they experience symptoms such as prolonged pain or fever after ureteroscopy.
Ureteroscopy is considered a safe and effective method for treating ureteral stones and offers a suitable option for the right conditions.
4. Open Surgery
In rare cases and when other methods are not applicable or have failed, open surgery may be required. This method uses direct incisions for manual removal of the stone and is usually used as a last resort in complex cases where other minimally invasive methods cannot be used.
Patient Questions and Answers
Surgical treatment options for ureteral stones includedepends on the size, location and the patient's symptoms. Patients often have various questions about these treatments. Here are the frequently asked questions and answers about these treatments:
Question: What surgical methods are used for the treatment of ureteral stones?
Answer: There are three main methods used for the surgical treatment of ureteral stones;
- Ureteroscopy: This is the most commonly used method. An endoscope is passed through the ureter and the stones are either directly visualized and removed or broken up with a laser.
- Shock Wave Lithotripsy (ESWL): Uses high-energy waves to break up the stone. This method is non-invasive and is effective depending on the part of the stone in the ureter.
- Percutaneous Nephrolithotomy: Used for very large or hard-to-reach stones. The kidney is entered directly through a small incision and the stone is removed.
Question: What is the recovery process after surgical treatment?
Answer: The recovery process varies depending on the surgical method chosen. Ureteroscopy usually has a rapid recovery time and normal activities can be returned within a few days. A similarly short recovery period is observed after ESWL. Percutaneous nephrolithotomy is more invasive, so the recovery time may be slightly longer.
Question: Will there be pain after surgery?
Answer: Yes, most patients experience some pain after surgery, but this is usually manageable and temporary. Your doctor will prescribe appropriate painkillers.
Question: Will stones recur after surgery?
Answer: Yes, stones can recur. It is important to drink plenty of fluids, eat a healthy diet, and take medication when necessary to reduce the risk of recurrence.
Question: When can I return to work after surgery?
Answer: This depends on the surgical procedure performed and the nature of your job. After ureteroscopy and ESWL, you can return to work within a few days, while after percutaneous nephrolithotomy, it may take several weeks.
Question: Are there alternative treatments to surgery?
Answer: For small stones, drug treatments such as medical expulsive therapy (MET) may be an alternative. Additionally, lifestyle changes such as regular exercise and drinking plenty of fluids can help prevent stone formation.
Question: What is the risk of complications during surgery?
Answer: As with any surgical procedure, there is a risk of complications, but these are minimal. Potential complications include infection, bleeding, or, rarely, damage to the ureter. However, an experienced surgeon can minimize these risks.
Question: What kind of follow-up treatments are needed after treatment?
Answer: Regular follow-ups after treatment are important to confirm that the stone has been completely removed and has not recurred. This is usually done with an ultrasound, X-ray, or sometimes a CT scan.
Question: What changes should I make to my diet after treatment?
Answer: Avoiding high-oxalate foods, limiting salt and protein intake, and drinking plenty of fluids are recommended. These changes can help prevent new stones from forming.
Question: How much does ureteral stone treatment cost?
Answer: The cost can vary depending on the treatment method, geographic location, and your health insurance coverage. Consult your health insurance provider or treatment center for detailed information.
