Practical Matters: Radiography helps confirm complete radiopaque calculi removal
Residual calculi may be responsible for acute urethral obstruction and can cause a poor response to antibiotic therapy for bladder infections after surgery. In addition, incomplete calculi evacuation may be misinterpreted as a failure of the medical therapy to prevent stone recurrence after surgery and may unnecessarily alter future diagnostic test and treatment plans.
When calculi have been removed completely yet the condition recurs early after surgery, owners may blame the surgeon for incomplete removal. Thus, to verify complete calculi removal and reduce these concerns, take orthogonal radiographs after cystotomy.Daniel D. Smeak, DVM, DACVS
