Background: Functional outflow tract obstruction (FOO) remains a challenging disease to manage in male dogs. Cystostomy tubes have been used to relieve urethral obstruction while allowing time to achieve effective medical management, avoiding the need for emergency visits and repeat urinary catheterizations.
Objectives: To describe a series of dogs with FOO and categorize the most successful management strategies including medical management alone or with the support of cystostomy tubes for urinary diversion.
Objective: To assess outcomes of dogs with side-to-side portocaval extrahepatic portosystemic shunts (PC-EHPSS) and poor portal perfusion to the liver treated with medical management alone (MM) or surgical attenuation (SA).
Study Design: Multi-institutional retrospective study.
Animals: A total of 21 dogs with PC-EHPSS (14/21 MM and 7/21 SA).
Article Synopsis
- Minimally invasive treatments for upper urinary tract uroliths (kidney stones) are the standard in humans and this study explores their application in dogs.
- A total of 6 female dogs with various combinations of kidney and ureter stones were treated using dietary changes, antibiotics, and ureteral stenting, achieving significant urolith dissolution over several months.
- The results suggest that medical dissolution can be an effective strategy for treating struvite uroliths in dogs, potentially avoiding the need for more invasive surgical procedures.
Article Synopsis
- This study focused on the success of two devices, the subcutaneous ureteral bypass (SUB) and self-expanding metallic stents (SEMS), used to relieve urinary obstructions in cats with malignant tumors, specifically transitional cell carcinoma (TCC).
- A total of 14 cats were examined, with different obstruction types; findings showed that SUB devices effectively prevented recurrent ureteral obstructions, while SEMS had a significant rate of re-obstruction.
- Overall, the study concluded that these devices are effective for immediate relief of urinary blockages in cats, and using additional therapies alongside could enhance survival times for those affected by TCC.
Anatomical classification of canine congenital extrahepatic portosystemic shunts based on CT angiography: A SVSTS and VIRIES multi-institutional study in 1082 dogs.

Canine congenital extrahepatic portosystemic shunt (EHPSS) morphologies have not been fully elucidated. The goal of this retrospective, multi-institutional study was to use CT angiography to create an anatomical-based nomenclature system for canine congenital EHPSS. These shunt morphologies were then evaluated to identify any significant association with patient age, sex, breed, weight, or subjective portal perfusion score.
