Ureteroscopy for Stones in Korea

Ureteroscopy is a common and effective minimally invasive procedure used to diagnose and treat stones located in the ureter (the tube connecting the kidney to the bladder) and kidney. In Korea, urologists frequently perform ureteroscopy for various stone issues, utilizing flexible or rigid scopes and laser technology to break or remove stones. This procedure offers high success rates for stone clearance, helping patients alleviate pain and prevent complications associated with urinary tract stones.

Understanding Ureteral/Kidney Stones & Indications in Korea

Stones in the ureter or kidney can cause significant discomfort and health issues.

• Location: Stones can form in the kidney and then travel down the ureter, often getting stuck and causing obstruction.
• Symptoms: Severe, colicky pain (renal colic), blood in the urine (hematuria), nausea, vomiting, and potential for infection.
• Indications for Ureteroscopy: Primarily used for ureteral stones that are too large to pass spontaneously, cause severe pain, obstruction, or are associated with infection. It's also effective for kidney stones, especially those in the lower pole or when ESWL (shock wave lithotripsy) is not suitable.
• Diagnosis: In Korea, diagnosis involves a physical exam, urinalysis, and imaging studies such as X-rays, ultrasound, or CT scans to pinpoint the stone's size, location, and composition.

Common Ureteroscopy Procedures in Korea

Ureteroscopy involves inserting a thin, lighted tube with a camera into the urinary tract.

• Procedure:

1. Performed under general or regional anesthesia.
2. A thin ureteroscope (either semi-rigid or flexible) is inserted through the urethra, navigated through the bladder, and up into the ureter to reach the stone. Flexible ureteroscopes can even reach stones within the kidney.
3. Once the stone is visualized, a laser (commonly Holmium laser) is used to fragment the stone into smaller pieces.
4. Smaller fragments may pass naturally, or larger pieces can be retrieved with a small basket-like device.
5. A temporary ureteral stent (a small tube) may be placed to ensure proper drainage and reduce swelling, typically removed a few days to weeks later.

• Types of Scopes: Flexible ureteroscopes offer greater maneuverability for complex stones, especially in the kidney, including lower pole stones. Rigid ureteroscopes are often used for stones in the lower ureter.
• Duration: The procedure typically takes 30 to 90 minutes, depending on the stone's complexity.

Recovery & Outcomes in Korea

Recovery after ureteroscopy is generally quick, with most patients returning home the same day or within 24 hours.

• Post-Procedure: Patients may experience mild discomfort, urgency, frequent urination, and blood in the urine, especially if a stent is placed. Pain medication is usually prescribed.
• Activity Restrictions: Strenuous activities, heavy lifting, and sexual activity are typically restricted for 1-2 weeks.
• Stent Removal: If a ureteral stent is placed, it is usually removed in an outpatient clinic visit, sometimes via a string attached to the stent.
• Success Rates: Ureteroscopy has high stone-free rates, often exceeding 85-95% for ureteral stones, and comparable high rates for kidney stones, depending on size and location.
• Complications: Risks are generally low but can include temporary discomfort, infection, minor ureteral injury (perforation, stricture), or a retained stone fragment requiring further treatment. Serious complications like ureteral avulsion are extremely rare.

Korean Guidelines & Practice

Ureteroscopy is a well-established and frequently performed procedure in Korean urology.

• Expert Urologists: Performed by highly skilled urologists in major university hospitals and specialized clinics throughout Korea. Many have extensive experience in endourology.
• Advanced Technology: Korean hospitals often utilize advanced laser systems (e.g., Holmium laser) and high-definition flexible ureteroscopes, including single-use devices, for precise and effective stone fragmentation.
• Integrated Care: Procedures are often part of a comprehensive stone management plan, including post-operative follow-up and metabolic evaluation to prevent recurrence.
• National Health Insurance: Ureteroscopy for medically indicated kidney or ureteral stones is generally covered by Korea's National Health Insurance. The cost to the patient will depend on their co-payment rate and specific hospital charges.

Key Takeaways for Ureteroscopy for Stones in Korea

To summarize the essential points about Ureteroscopy for Stones in Korea:

• Minimally Invasive: Uses a scope inserted via the urethra to treat ureteral and kidney stones.
• Laser Technology: Often employs laser lithotripsy to break stones for removal or passage.
• High Success: Effective with high stone-free rates for various stone sizes and locations.
• Quick Recovery: Generally an outpatient procedure with minimal downtime; discomfort often managed with medication.
• Expert Care & Covered: Performed by skilled urologists with advanced equipment, and generally covered by national health insurance for medical indications.
