Post-traumatic urinoma in two cats: Imaging diagnosis

Abstract

A urinoma is a collection of urine surrounded by a fibrotic wall and, in the veterinary medicine, this condition is rarely reported. The aim of this study is to describe the clinical and therapeutic features of two cats with post traumatic urinomas, with particular attention paid to the imaging findings. In both patients, well-defined anechoic fluid collections in the retroperitoneal space were identified by ultrasound examinations and the laboratory tests suggested the urinous nature of the fluid. With excretory urography, the only relevant findings revealed were the abdominal and retroperitoneal loss of detail, whereas the combination of multiple techniques in Case 1 and the delayed study in Case 2, detected contrast leakage and fluid collections in the retroperitoneal space. Both patients fully recovered after either surgical or conservative treatments. In conclusion, different imaging modalities have been helpful to properly diagnose urinomas in cats and especially combined and/or delayed studies were of paramount importance for the final diagnosis.

The Imaging Diagnosis of Patients with Shoulder Pain Caused by Sports Injury

“…This article mainly uses Philips 3.0 MRI to examine the patient, selects a special scanning system for the limbs and joints, and assists the patient to adopt a supine position, keep the upper limbs in a neutral position, and use a coil to wrap the shoulder joint of the patient's side; give the disease Patients with oblique coronal position PDWIFSET1WI, horizontal axis position PDWIFSET1WI, oblique sagittal position PDWI fat suppression sequence scan, PDWI-FST2WI if necessary, parameter setting: layer thickness 3.0 mm~4.0 mm, matrix 288 × 224, FOV is 18 × 18 mm. Arthroscopy: the patient sits on the beach or in a chair, is anesthetized regularly, and uses traditional medicine to help diagnose the shoulder joint by applying the assault joint system [ 25 ].…”

Nontraumatic Paraureteral Urinoma in a Cat with Urolithiasis

“…The combination of imaging, and clinical and laboratory findings led us to the suspected diagnosis. The ultrasound-guided percutaneous contrast inoculation helped in radiographically outlining the well-encapsulated fluid collection and differentiating it from ascite, playing a role in the decision to propose the surgery in order to find the source of extravasation and to perform the fluid drainage, as recommended by previous studies [ 8 , 10 , 12 ]. The early death of patient did not allow for performing it.…”

“…In human medicine, urinoma is widely reported because of blunt or penetrating trauma, fibrosis, or a surgery of the retroperitoneal space, intra-abdominal neoplasms, and urinary-tract obstruction by uroliths [ 1 , 4 , 5 ]. In veterinary medicine, urinoma is an uncommon condition with few reports described in small and large animals [ 6 , 7 , 8 ]. In cats, urinomas are often described as post-traumatic in nature.…”

“…In cats, urinomas are often described as post-traumatic in nature. The radiography, ultrasonography, excretory urography, and computed tomography of pseudocysts and the urinary tract were used to diagnose urinomas [ 8 , 9 , 10 , 11 , 12 ]. This study describes the clinical and diagnostic findings of a well-encapsulated paraureteral urinoma associated with urinary-tract stones in a critical feline patient.…”

Urinary Tract Trauma in Cats: Stabilisation, Diagnosis and Management

“…Patients with a urinoma usually present several weeks after the initial trauma as the urinoma increases in size due to ongoing urine accumulation. [35][36][37][38][39] The clinical signs associated with urinoma are usually non-specific, such as anorexia, depression, lethargy and weight loss, although presence of a mass/ swelling in the dorsal mid-abdomen may help to narrow the differential diagnoses (Figure 4a). Hematobiochemical analysis may detect mild azotaemia and a non-specific inflammatory leukogram.…”
