“…Clinical signs present with this case included only weight loss and polyuria. Unlike the previous case report of ureteral hemangiosarcoma [9], our patient was not noted to have hematuria. The vague clinical signs associated with a ureteral mass are broad and may be attributed to a multitude of different diseases, warranting a complete and thorough diagnostic evaluation as necessary for an accurate diagnosis [9].…”

“…Similar to the previously documented case of ureteral hemangiosarcoma, our patient's pre-operative thoracic radiographs did not reveal any signs of metastatic disease indicating our patient was a suitable candidate for an exploratory celiotomy [9]. Treatment options for a ureteral mass commonly include surgical resection, specifically by ureteroneocystostomy or ureteronephrectomy [6,9,28,29].…”

“…In this case report, abdominal CT confirmed the presence of a distal ureteral mass with secondary hydroureter. As in people, distal ureteral masses in dogs are more likely to be malignant, whereas proximal ureteral masses are more likely to benign [4,9,12,26,27]. The histopathology results in this case report of malignant tumor of the distal ureter are supported by these previous findings.…”

“…Previously reported ureteral tumors include leiomyosarcoma, fibroepithelial polyps, fibropapilloma, transitional cell carcinoma, mast cell tumors, giant cell sarcoma and leiomyoma [2,4,6,8,[11][12][13][14][15]. Hemangiosarcoma is a well-known malignant tumor originating from vascular endothelial cells [2,9,16,17]. The most common primary sites reported for hemangiosarcoma include the spleen, right atrium, liver, and skin (particularly the dermis and subcutis) [9,17,18].…”

“…The most common primary sites reported for hemangiosarcoma include the spleen, right atrium, liver, and skin (particularly the dermis and subcutis) [9,17,18]. The canine urinary tract being a primary site of hemangiosarcoma is extremely rare [9,19,20]. Previous reports of hemangiosarcoma originating from the urinary tract were localized to the retroperitoneal space, kidney, urethra, prostate, and proximal ureter [9,[21][22][23][24][25].…”

Background Primary ureteral neoplasia in dogs is extremely rare. To the best of the authors’ knowledge, this is the second documented case of a primary ureteral hemangiosarcoma. This case report describes the clinical and pathological findings of a primary distal ureteral hemangiosarcoma. Case presentation A 12-year-old spayed female goldendoodle was presented with a history of polyuria and weight loss. Abdominal radiographs revealed a large cranial abdominal mass. Abdominal ultrasound and computed tomography (CT) identified a left sided distal ureteral mass with secondary hydroureter and a left lateral hepatic mass with no evidence of connection or diffuse metastasis. A left ureteronephrectomy, partial cystectomy, and left lateral liver lobectomy were performed. Histopathology was consistent with primary ureteral hemangiosarcoma and a hepatocellular carcinoma. Adjunctive therapy including chemotherapy was discussed but declined. Conclusion Due to its rarity, the authors of this case presentation believe that ureteral hemangiosarcoma should be included as a differential diagnosis when evaluating a ureteral mass. With the unknown, and suspected poor prognosis, routine monitoring with adjunctive therapy should be considered.

A ureteral rhabdomyosarcoma was diagnosed in a 2-year, 9-month-old, entire, male dobermann with persistent haematuria. Diagnostic imaging revealed unilateral hydronephrosis and hydroureter. In addition, it showed thickening of the distal ureteric wall and focal thickening of the mucosa of the bladder trigone between the ureters. No mass was identified. The patient underwent exploratory laparotomy, and biopsies of the bladder mucosal thickening and right ureteral thickening were obtained. Histopathology of the ureteral thickening was suggestive of a ureteral rhabdomyosarcoma. A right ureteroneocystostomy was performed, and histopathology confirmed the suspected ureteral rhabdomyosarcoma, which was fully excised. Six months later, the patient remains asymptomatic with no evidence of recurrence or metastases on abdominal ultrasonography.

A 5‐year‐old spayed female Maltese presented with a 1‐week history of severe hematuria. Abdominal ultrasonography and thoracic, and abdominal computed tomography identified bilateral hydronephrosis and hydroureter due to an obstruction at the left ureter and urinary bladder lesion with no evidence of metastasis. After surgical removal of the material and placement of a temporary ureteral stent, the patient was able to urinate normally. Histological examination revealed a massive blood clot. Based on our review of the literature, this is the first published report describing the imaging diagnosis of obstructive hydronephrosis and hydroureter induced by idiopathic renal hematuria in a dog.
