Study Population
Patient suffered upper ureteric stone
Criteria

Inclusion Criteria:

  • 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

Exclusion Criteria:

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