ABSTRACT
Surgical repair is frequently effective at resolving uroperitoneum in foals, though complications occur. Despite their occurrence, management strategies used to address these complications, and their impact on survival are not clearly defined. To better describe the complications following surgical correction of uroperitoneum and to document treatment strategies and outcomes after intervention, a multi-center retrospective case series was performed. Medical record data of foals undergoing surgical treatment for uroperitoneum were retrieved from three surgical centers, and cases identified with complications or comorbidities were reviewed. Long-term follow-up was obtained through owner contact. Of 45 foals with uroperitoneum, 13 (29%) had complications or comorbidities following surgical repair. Uroperitoneum recurred in 9 (20%) foals 12-264 hours after surgery. Foals with recurrence were managed medically with an indwelling urinary catheter, repeat celiotomy, or were euthanized. Other comorbidities following repair included sepsis and persistent azotemia. One horse developed cystic calculi 14 months later. Urinary catheters maintained for 3-7 days in combination with medical and surgical interventions successfully resolved uroperitoneum. The decision to debride bladder tear edges or the selection of suture material or pattern did not impact recurrence or survival. Six (67%) foals with recurrent uroperitoneum survived to hospital discharge; 86% survived if treatment was attempted. Four (80%) of cases treated for recurrent uroperitoneum were alive without active medical problems >2 years later. Despite recurrence, medical or surgical treatment of recurrent uroperitoneum enables short-term survival, and maintenance of long-term health. Indwelling urinary catheters should be considered in select cases with recurrent uroperitoneum.
