Cats exhibit high susceptibility to urinary organ-related diseases. We investigated the healthy ureter morphologies and compared these with ureters that were surgically resected distal to a urolithiasis obstruction in cats. Healthy ureters (total length 9.88 ± 0.38 cm) developed adventitia composed ...

Currently, there has been an increased risk of ureterolithiasis in cats; most of these stones are calcium oxalate ones, and responsible for ureteral obstruction. Feline ureteral obstruction may occur due to either the stone itself or may be secondary to ureteral fibrosis or granuloma formation. Due ...

Objectives: The aim of this report was to describe the clinical signs, diagnostic imaging findings, surgical management, histopathological findings, outcome and possible risk factors for cats that developed retroperitoneal fibrosis (RPF) following renal transplantation. Methods: Medical records of ...

Objectives: The objective was to identify clinical or ultrasonographic results associated with ureteral obstruction or outcome in cats with azotaemia. Methods: This was a retrospective cross-sectional study of cats with azotaemia (serum creatinine >180 µmol/l) that had ultrasonography of the...

Retrocaval ureter (RU) is an abnormal embryonic development of the caudal vena cava (CVC) that leads the ureter to be entrapped dorsal to the CVC. In most cases there is no clinical impact; however, it can cause hydronephrosis. We report a rare case of type II symptomatic retrocaval ureter in a ...

Objectives: The aim of the study was to describe renal pelvis (RP) and ureteral ultrasonographic measurements in a population of cats with confirmed benign ureteral obstruction (UO) by antegrade pyelography. The secondary objective was to further describe clinical findings associated with minimally ...

Feline transitional cell carcinoma (TCC) is a rare neoplasia of cats with an estimated prevalence of 0.18%. Cats with TCC share clinical signs with common pathologies like feline idiopathic cystitis or urinary tract infections. Nonspecific clinical signs include hematuria, pollakiuria, or...

In the last decades there has been an increase in diagnosis and treatment of feline ureteral disease. The treatment of ureteral pathologies can be difficult because of the small size of the ureter and critical condition of these patients at presentation. Multiple surgical procedures for the...

Practical relevance: Abdominal ultrasound plays a vital role in the diagnostic work-up of many cats presenting to general and specialist practitioners. Ultrasound examination of the urinary tract provides important information useful in the investigation of several conditions including ureteral ...

Objectives: The aim of this study was to evaluate the efficacy and tolerability of a 4% tetrasodium EDTA (tEDTA) infusion protocol in the subcutaneous ureteral bypass (SUB) devices of cats with intraluminal obstruction at a veterinary teaching hospital between July 2017 and April 2020. Methods:...
