About

The purpose of this research is to assess the role of non-contrast helical computerized tomogram in predicting the treatment outcome of upper ureteric stone by extracorporeal shock wave lithotripsy (ESWL).

Enrollment: 100 estimated patients

Sex: All

Ages: 18+ years old

Volunteers: No Healthy Volunteers

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
