Risks of Ureteroscopy for Stone Removal in China
Ureteroscopy is generally considered a safe and established procedure when performed by an experienced urologist in a properly equipped hospital. However, complications can occur.
Potential Risks
1. Urinary infection
A urinary tract infection can occur after the procedure. Rarely, a serious infection can develop.
2. Bleeding
Small amounts of blood in the urine are common for a short time. Significant bleeding is uncommon.
3. Ureter injury
The ureter can become irritated, perforated, or injured during the procedure. Serious injuries are rare.
4. Ureter narrowing
Scar tissue can sometimes form later and narrow the ureter.
5. Pain and urinary symptoms
Patients may experience burning while urinating, bladder discomfort, frequent urination, or cramping.
6. Stent-related problems
A temporary stent may cause discomfort, urgency, or blood in the urine until it is removed.
7. Incomplete stone removal
Large or multiple stones may require a second procedure.
8. Anesthesia risks
Reactions to medicines, breathing problems, or other anesthesia-related complications can occur.
Factors That Affect Safety
Surgeon experience: An experienced urologist who regularly performs flexible or rigid ureteroscopy can help reduce technical risks.
Hospital facilities: Good imaging, modern ureteroscopes, laser equipment, anesthesia services, infection control, and emergency care are important.
Stone characteristics: Large, hard, multiple, or difficult-to-reach stones can make the procedure more complex.
Existing infection: A urine infection before treatment can increase the risk of serious postoperative infection. It should be identified and treated appropriately.
Patient health: Age, diabetes, obesity, kidney disease, heart or lung conditions, and other medical problems can affect safety and recovery.
Anesthesia: Proper preoperative assessment and monitoring during anesthesia help reduce risks.
Factors Affecting Recovery
Recovery may take longer when there is:
- A large or multiple stone burden
- A ureteral injury
- Infection
- Prolonged or complex surgery
- A ureteral stent
- Other medical conditions
- A need for a second procedure
Good postoperative care, taking prescribed medicines, following activity instructions, attending follow-up appointments, and having the stent removed when advised can support recovery.
When to Seek Medical Help
Patients should contact their medical team urgently if they develop fever or chills, severe or worsening pain, heavy bleeding or blood clots, inability to urinate, persistent vomiting, or severe weakness.
Overall
For patients having ureteroscopy in China, safety depends mainly on urologist experience, hospital facilities, infection control, anesthesia, stone characteristics, the patient's health, and postoperative monitoring. Choosing a hospital with strong urology and emergency services is especially important for large or complicated stones.
