Study Population

Patient suffered upper ureteric stone

You may qualify if:

  • Adult patient (\> 18 years old)
  • With solitary upper ureteric stone (defined as ureter above the sacroiliac joint as seen on plain radiography) diagnosed by NCHCT \*(\* can have stones at the other site but the indexed stone is a solitary stone)
  • Size 5 to 15 mm in the maximal diameter as measured from plain radiography.
  • Planned for primary in-situ ESWL

You may not qualify if:

  • Patient contraindicated for ESWL - active urosepsis, coagulopathy, pregnant lady etc
  • Presence of percutaneous nephrostomy or ureteric stent
  • Suspected distal obstruction
