From the Guidelines
Yes, a 5 mm calculus at the distal left ureter causing mild pelvicalyceal system dilatation is generally not the first-line treatment option for Extracorporeal Shock Wave Lithotripsy (ESWL), but rather Ureteroscopy (URS) is recommended as the first-line therapy for mid or distal ureteral stones, according to the American Urological Association/Endourological Society guideline 1.
Key Considerations
- The stone's location (1 cm proximal to the vesicoureteric junction) and size (5 mm) are important factors in determining the treatment approach.
- URS is associated with significantly higher stone-free rates in a single procedure compared to SWL, particularly for patients with <10 mm mid and distal ureteral calculi 1.
- The choice between ESWL and ureteroscopy depends on stone characteristics, patient factors, and equipment availability, so the final decision should be made after consultation with a urologist.
Treatment Approach
- URS is recommended as the first-line therapy for mid or distal ureteral stones, with a stone-free rate of 90% compared to 72% for SWL 1.
- ESWL may be considered as an alternative treatment option if the patient declines URS or if URS is not feasible.
- Post-procedure care, including increased fluid intake, pain management, and follow-up imaging, is crucial to ensure optimal outcomes.
Important Considerations
- The patient should be informed about the attendant risks of each treatment modality, including the relative benefits and risks associated with each option 1.
- The decision to proceed with ESWL or URS should be made after a thorough discussion with the patient, taking into account their individual circumstances and preferences.
From the Research
Indications for ESWL
- The patient has a mild dilatation of the pelvicalyceal system on the left side with a dilated ureter secondary to a calculus of 5 mm at the most distal part of the left ureter (1 cm proximal to the left vesicoureteric junction).
- The size and location of the stone are important factors in determining the suitability of Extracorporeal Shock Wave Lithotripsy (ESWL) as a treatment option.
Treatment Options
- ESWL is a non-invasive treatment option for kidney stones, but its effectiveness depends on various factors, including stone size, location, and composition 2.
- Ureteroscopy with laser lithotripsy is another treatment option for kidney stones, which can be more effective for larger stones or stones that are not responsive to ESWL 3, 4.
- The choice of treatment depends on the individual patient's condition and the specific characteristics of the stone.
Stone Size and Location
- The stone in question is 5 mm in size and located in the distal part of the left ureter, which is a relatively small stone that may be suitable for ESWL 2.
- However, the mild dilatation of the pelvicalyceal system and the dilated ureter may indicate a higher risk of complications or reduced effectiveness of ESWL.

Additional Considerations
- The patient's overall health and medical history should be taken into account when determining the best course of treatment.
- The potential risks and benefits of each treatment option should be carefully considered and discussed with the patient.
- Further evaluation and consultation with a urologist or other qualified healthcare professional may be necessary to determine the most appropriate treatment plan 3, 2, 4, 5, 6.
