Summary
Ureterocolonic anastomosis in dogs can be a salvage procedure for cystectomy but may lead to metabolic acidosis, hyperammonemia, and neurologic issues. Kidney damage, including pyelonephritis, was also observed post-surgery.
Area of Science:
- Veterinary Surgery
- Urology
- Nephrology
Background:
- Ureterocolonic anastomosis is a surgical technique used in dogs.
- This procedure is considered a salvage option for complete cystectomy.
- Potential complications require thorough evaluation.
Purpose of the Study:
- To evaluate the outcomes of ureterocolonic anastomosis in clinically normal dogs.
- To assess urinary continence and identify postoperative complications.
- To investigate the incidence of metabolic disturbances and renal pathology.
Main Methods:
- 13 clinically normal dogs underwent ureterocolonic anastomosis.
- Postoperative monitoring included clinical signs, plasma ammonia, and serum chemistry.
- Kidney function and pathology were assessed via urinalysis, glomerular filtration rate, and histopathology at various intervals.
Main Results:
- Urinary continence was maintained in most dogs.
- Complications included gastrointestinal and neurologic disturbances, with elevated plasma ammonia in affected dogs.
- Metabolic acidosis, hyperammonemia, and renal complications like pyelonephritis were observed.
- Increased serum urea nitrogen due to colonic absorption and reduced glomerular filtration rate were noted.
Conclusions:
- Ureterocolonic anastomosis can serve as a salvage procedure enabling cystectomy.
- The procedure carries risks of metabolic acidosis, hyperammonemia, and neurologic complications.
- Renal pathology, particularly pyelonephritis, is a significant concern following ureterocolonic anastomosis.
