Alternatives to Ureteroscopy in China
Patients with urinary stones may have several treatment options besides ureteroscopy. The best choice depends on the stone's size, location, composition, symptoms, blockage, infection, and the patient's overall health.
1. Shock Wave Lithotripsy
Shock wave lithotripsy (SWL or ESWL) uses focused sound waves to break a stone into smaller pieces that can pass through the urine.
It may be considered when:
- The stone is relatively small.
- The stone can be clearly targeted.
- There is no serious urinary infection.
- The stone's location is suitable for shock-wave treatment.
- The patient wants a less invasive option.
SWL may be less effective for very large, hard, or deeply positioned stones. Some patients may need more than one treatment.
2. Medication
Medical expulsive therapy may be considered for selected small ureteral stones that are likely to pass naturally.
Medicines may:
- Relax the ureter.
- Help stone passage.
- Reduce pain.
- Control nausea or other symptoms.
This approach is generally considered only when there is no serious infection, severe obstruction, kidney damage, or uncontrolled pain.
3. Observation and Natural Stone Passage
Small stones may sometimes pass without a procedure.
The doctor may recommend monitoring with imaging while the patient uses pain control and appropriate fluids. The patient needs follow-up to make sure the stone passes and does not continue to block the urinary tract.
4. Percutaneous Nephrolithotomy
Percutaneous nephrolithotomy (PCNL) removes stones through a small opening made through the skin into the kidney.
It is mainly considered for large kidney stones, particularly stones that are too large or complex for ureteroscopy or SWL.
5. Combination or Staged Treatment
Some patients may need more than one treatment. For example, SWL can be tried first and ureteroscopy can be used if the stone does not clear.
For very large or complex kidney stones, doctors may use PCNL, flexible ureteroscopy, or a combination of techniques.
When Is Ureteroscopy Preferred?
Ureteroscopy may be preferred when:
- The stone is large.
- The stone is difficult to target with SWL.
- SWL has failed.
- The stone is causing significant blockage.
- There is persistent severe pain.
- The stone is unlikely to pass naturally.
Important Consideration
If a stone is causing urinary obstruction together with a serious infection, this requires urgent medical treatment rather than simply waiting for the stone to pass.
Overall
In China, treatment options can include observation, medication, shock wave lithotripsy, ureteroscopy, and PCNL. The urologist usually chooses the approach based on the stone's size, location, hardness, blockage, infection risk, kidney function, and the patient's preferences.
