Objective-To determine results of ultrasound-guided cystocentesis and percutaneous infusion of Walpole's
solution for treatment of male
goats with urolithiasis. Design-Retrospective case series. Animals-25 male
goats with urolithiasis treated with Walpole's
solution. Procedures-Information obtained from the medical records included signalment, degree of
urethral obstruction (partial vs complete), pertinent examination findings, concurrent illnesses, diet, other treatments administered, duration of hospitalization, whether the obstruction resolved, and outcome (ie, discharged vs
euthanized). Results-14 (58%) animals had complete
urethral obstruction, and 10 (42%) had partial obstruction (degree of
urethral patency was not recorded in 1 animal). Walpole's
solution was infused once in 18 (72%) animals, twice in 6 (24%) animals, and 3 times in 1 (4%) animal. The amount of Walpole's
solution required to achieve the target
urine pH of 4 to 5 ranged from 50 to 250 mL. In 20 (80%)
goats, the
urethral obstruction resolved, and the
goat was discharged. The remaining 5 (20%)
goats were
euthanized because of unresolved
urethral obstruction. Six of the 20 (30%)
goats that were discharged were reexamined because of recurrence of
urethral obstruction. Conclusions and Clinical Relevance-Results suggested that ultrasound-guided cystocentesis in combination with percutaneous infusion of Walpole's
solution may be a useful treatment in male
goats with obstructive urolithiasis.
