Results indicated renomegaly was not associated with ureteral obstruction in cats, and abdominal palpation was an unreliable method for detection of renomegaly. The most consistent abnormal finding for cats with ureteral obstruction was hypercreatininemia.
CASE DESCRIPTION A 4-year-old spayed female Beagle was evaluated because of a 2-month history of intermittent pollakiuria, stranguria, dysuria, and abdominal pain. A diagnosis of bacterial cystitis was initially made, but clinical signs persisted despite appropriate antimicrobial treatment, so the dog was referred for further evaluation and treatment. CLINICAL FINDINGS Abdominal ultrasonography revealed a large, thin-walled, cystic structure in the urinary bladder at the level of the expected right ureterovesicular junction that communicated with the uniformly dilated right ureter. Severe right-sided pyelectasia was also detected. A presumptive diagnosis was made of a right-sided orthotopic ureterocele with secondary hydroureter and pyelectasia. TREATMENT AND OUTCOME Cystoscopy revealed a large cystic structure in the region of the right ureterovesicular junction without obvious communication between the ureter and urinary bladder. Portable C-arm fluoroscopy was used to confirm the presence of an intramural orthotopic tract and to measure the diameter of the ureter and renal pelvis via retrograde contrast ureteropyelography. Complete laser ablation of the ureterocele was performed by incising it circumferentially near its base. Clinical signs resolved immediately following the procedure. Six weeks later, the dog remained free of clinical signs and abdominal ultrasonography revealed resolution of hydroureter with persistence of mild right-sided pyelectasia. CLINICAL RELEVANCE Cystoscopic-guided laser ablation of an orthotopic ureterocele secondary to ureterovesicular stenosis was a safe and effective minimally invasive treatment for the dog of this report, resulting in immediate and continued improvement of clinical signs and ultrasonographic changes. Laser ablation should be considered as an alternative to surgery for the treatment of orthotopic ureteroceles in dogs.
CASE DESCRIPTION A 7-year-old 44-kg (97-lb) neutered male Great Pyrenees was referred for evaluation because of episodic dyspnea with cyanosis of 1 to 2 weeks' duration. Three days prior to evaluation, the clinical signs had worsened, including 1 episode of collapse. CLINICAL FINDINGS Thoracic radiography and CT revealed a well-delineated soft tissue mass, located approximately 1.5 cm cranial to the carina and occupying almost 90% of the tracheal lumen. A CBC and serum biochemical analysis were performed, and all results were within reference limits. TREATMENT AND OUTCOME Tracheoscopy confirmed the presence of a broad-based bilobate mass that was protruding from the right dorsal aspect of the trachea and occupied almost the entire tracheal lumen. The mass was successfully resected by endoscopic-guided electrocautery ablation. Findings of histologic evaluation were consistent with a diagnosis of liposarcoma. Immediately following the ablation procedure, the previously noted clinical signs of respiratory tract disease resolved. On follow-up examination 12 months later, no regrowth of the mass was evident on thoracic helical CT and tracheoscopy. CLINICAL RELEVANCE Endoscopic-guided electrocautery ablation of tracheal liposarcoma was a safe and effective minimally invasive treatment for the dog of this report. The procedure was brief and appeared to be well tolerated, resulting in immediate improvement of clinical signs.
The following report describes the unique procedure currently emerging to treat spondyloptosis. Here we describe the case of K.P. 17 year old female who had been diagnosed with spondylolisthesis. Her chief complaint was lower mechanical back pain, for which she underwent a lumbar-sacral fusion procedure in Port of Spain General Hospital in 2011. Upon follow up in clinic, she presented with severe axial / mechanical back pain which was affecting her lifestyle. This progressively became worse. On further evaluation a spondyloptosis of L5/S1 was diagnosed and despite previous fusion, a Modified Bohlman`s procedure with non-vascularized fibula autograft after decompression of L5 /S1 motion segment, was performed. This procedure has never been reported in the Caribbean region. The occurrence, pathomechanics, operative technique and outcomes are discussed in detail.
