A 4-year-old cat was presented for polyuria and polydipsia. Unilateral hydronephorosis and hydroureter was diagnosed on ultrasound examination of the abdomen, and right ureteral calculi were seen in survey abdominal radiographs. Intravenous urography confirmed hydronephrosis and indicated poor renal funttion in the right kidney. Surgical removal of the ureteral calculus improved right renal function. Analysis of the calculus indicated composition of calcium oxalate, an uncommon calculus in cats.  相似文献

A 9-month-old, castrated male domestic shorthair cat with urinary incontinence was referred for surgical correction of an ectopic ureter. Excretory urography revealed hydronephrosis of the right kidney, right hydroureter, and ureterocele. A partial ureterocelectomy and neoureterocystostomy were performed. This report describes the surgical modification of the ureterocele and ectopic ureter to correct ipsilateral hydronephrosis, hydroureter, and urinary incontinence.  相似文献

BackgroundCircumcaval ureter is an anomaly in the development of the caudal vena cava, rarely reported in ferrets.Materials and methodsInclusion criteria for ferrets were circumcaval ureter confirmed on surgery or post-mortem examination. Data collection of ferrets with circumcaval ureters presented between January 2014 and January 2021 included signalment, medical history, clinical signs, laboratory diagnostics, diagnostic imaging results, treatments, and clinical outcomes.ResultsTwo ferrets met the inclusion criteria. One presented following diarrhea, and one was found on routine examination that revealed a right nephromegaly. Abdominal ultrasound revealed severe unilateral hydronephrosis associated with hydroureter in both ferrets. No obvious cause of obstruction was identified. Biochemical results were unremarkable in both patients. Hydronephrosis was investigated through CT scans, revealing Type 1 circumcaval ureter in both ferrets. Section and relocation of the right ureter by uretero-vesical anastomosis was performed in one ferret. This ferret died 48 hours later following a nephrectomy performed due to persistent hydronephrosis. The second cas underwent right nephrectomy andd ureter resection due to severe hydronephrosis and stenosis of the circuncaval segment. This ferret has remained healthy on followup with no abnormalities found in biochemistries or ultrasound examination.Conclusion and case relevanceFindings suggest that circumcaval ureter should be suspected in ferrets with unilateral hydronephrosis and associated hydroureter without any identified cause of obstruction on abdominal ultrasonography. It should be confirmed with CT scan and/or urography and treated surgically.  相似文献

An 8‐month‐old neutered male ferret was presented for vaccination and preventive treatment for adrenal gland disease. Abdominal ultrasound revealed severe bilateral hydronephrosis and hydroureter. Excretory urography and negative contrast cystography showed bilateral ureterovesical junction stenosis. Positive retrograde cystography demonstrated right ureteral reflux. A subcutaneous ureteral bypass was placed in the left kidney; however, it had to be removed 3 months later due to an obstruction and persistent urinary tract infection. Bilateral ureteroneocystotomy was performed. Although congenital strictures are uncommon in veterinary patients, they should be included in the differential diagnosis in ferrets presenting with hydronephrosis and hydroureter of undetermined cause.  相似文献

A 2.5-year-old, female opossum had acute stranguria. Based on radiography and ultrasonographic examination a cystic structure was identified in the caudal abdomen associated with bilateral hydroureter and hydronephrosis. This structure contained a neutrophilic fluid, determined to be urine. There was a neutrophilic leukocytosis. Serum chemistry values were within normal limits. The opossum was euthanized. An intra-abdominal fat pad incarceration of the urinary bladder above the trigone was present, resulting in complete obstruction of the urinary bladder and partial obstruction of the ureters. Vessels to the bladder were involved in the incarceration which resulted in vascular compromise and infarction of the bladder. Mild to moderate hydroureter and hydronephrosis were present.  相似文献

A nine-year-old female German shepherd dog was presented in severe renal failure. Clinical and ultrasonographic examination revealed the presence of adrenal neoplasia, bilateral hydroureter and hydronephrosis but no evidence of urolithiasis or bladder neoplasia. In the absence of anuria, therapy for the renal failure was attempted but the azotaemia did not improve. Remarkably, bilateral hydroureter appeared to have been induced by a past routine surgical procedure--ovariohysterectomy.  相似文献

Severe hydronephrosis and hydroureter associated with ectopic ureters were diagnosed in 2 dogs. Surgical transplantation of the ectopic ureters into the urinary bladder resulted in urinary continence in both dogs. Intravenous urography revealed a marked decrease in the size of hydronephrosis and hydroureter in both dogs 28 to 35 weeks after surgery. In 1 dog with bilateral ureteral ectopia, kidney size and renal function remained normal for 5 years after surgery. A dog with one ectopic ureter and an associated ureterocele had a marked reduction in size of the affected kidney and an apparent decrease in function of that kidney, as indicated by decreased opacification on an intravenous urogram.  相似文献

A 10-month-old, intact male chinchilla (Chinchilla lanigera) was diagnosed with urolithiasis, unilateral hydroureter, and hydronephrosis secondary to ureteral obstruction confirmed by radiography and ultrasonography. Nephrectomy and cystotomy were performed, and the urolith was suspected to be a semen-matrix calculus (mineralized copulatory plug) based on the discovery of sperm within the renal pelvis of the nephrectomized kidney on histopathology; this was later confirmed through a postmortem examination. Three months after initial presentation the chinchilla was diagnosed with recurrent urolithiasis, hydroureter, and hydronephrosis of the remaining kidney and ureter, and euthanized due to poor prognosis. Necropsy confirmed the presence of semen-matrix calculi in the ureter and urinary bladder. Veterinary clinicians should consider semen-matrix calculi as a differential diagnosis for radiopaque calculi within the bladder or urethra of male chinchillas. Pathogenesis may be formation of a coagulum secondary to retrograde ejaculation.  相似文献

Three dogs and one cat with lymphoma affecting the urinary bladder are reported and the findings on abdominal radiographs and ultrasound are described. Mural lesions representing lymphoma affecting the urinary bladder were identified ultrasonographically in all animals. The most common complications associated with urinary bladder lymphoma were hydronephrosis and hydroureter. In two patients contrast radiography was necessary to detect leakage of urine in the peritoneal and retroperitoneal space. The radiographic and ultrasonographic signs were similar to those reported with other urinary bladder neoplasms; hence urinary bladder lymphoma could not be distinguished from the more common urinary bladder neoplasms, such as transitional cell carcinoma. It is important to include lymphoma in the differential diagnosis of urinary bladder wall thickening and mural mass in dogs and cats.  相似文献

A captively maintained mature male opossum (Didelphis virginiana) utilized in a research protocol was presented with clinical signs of chronic diarrhea and severe muscle wasting. At necropsy, there was multifocal mural gastric, intestinal, and urinary bladder thickening, concurrent bilateral hydroureter and hydronephrosis, and extensive fibrous abdominal adhesions. Histologic evaluation revealed intestinal adenocarcinoma with coelomic metastasis to the stomach and urinary bladder. The adenocarcinoma was evaluated using histochemistry and electron microscopy. Paneth, enteroendocrine, and goblet cell differentiation was documented in primary and metastatic sites. This unique presentation of intestinal adenocarcinoma has not previously been reported in the opossum or any other animals. Intestinal neoplasia with Paneth cell differentiation is extremely rare and has been reported in humans with familial adenomatous polyposis.  相似文献

Progressive hydroureter and hydronephrosis were diagnosed in a dog after anastomosis of a crushed ureter. Nephrectomy was averted when partial resolution was noticed one month after the ureteral repair. The appearance of the kidney and ureter was nearly normal several months later. Conservative management should be considered in cases of partial unilateral ureteral obstruction.  相似文献

Severe hydroureter and hydronephrosis secondary to ureteral obstruction by calculus were present in a guinea pig. A palliative ultrasound-guided percutaneous antegrade hydropropulsion was performed under general anesthesia to relieve the ureteral obstruction and the associated clinical signs. We describe the technique and the considerations for its potential application in similar cases.  相似文献

A 2 1/2-month-old, female German Shepherd Dog was examined because of incontinence since birth. Multiple urinary anomalies which included left renal agenesis, right hydronephrosis and hydroureter and urinary bladder dysfunction were found by excretory urography. These abnormalities were confirmed at necropsy. In addition, vesicovaginal continuity with apparent absence of the urethra was also found  相似文献

CASE DESCRIPTION: A 4-month-old Bernese Mountain Dog was examined because of shifting hind limb lameness and lethargy of 2 weeks' duration. CLINICAL FINDINGS: The lameness was attributed to hypertrophic osteodystrophy. Portosystemic shunting was suspected on the basis of low serum albumin concentration and high serum bile acids concentration, and an intrahepatic shunt was identified ultrasono-graphically. Celiotomy was performed, and the shunt was partially closed with a cellophane band. During follow-up ultrasonography 7 months later, dilation of the left renal pelvis and proximal portion of the left ureter was identified. During exploratory celiotomy, the left ureter was found to pass dorsal to the caudal vena cava, and circumcaval ureter was diagnosed. TREATMENT AND OUTCOME: The ureter was transected, repositioned ventral to the vena cava, and anastomosed. Follow-up ultrasonographic examinations revealed gradual resolution of the hydronephrosis and hydroureter. CLINICAL RELEVANCE: Findings suggest that circumcaval ureter should be considered in the differential diagnosis for hydronephrosis and hydroureter in dogs. Partial obstruction of the middle segment of the ureter on ultrasonograms or contrast radiographs should increase the index of suspicion for this condition.  相似文献

A urinoma is an encapsulated extravasation of urine. In this case history report, the radiographic and ultrasonographic features of a urinoma in a dog are described. The dog presented with a palpable mass in the right flank which developed following ovariohysterectomy. Urinoma was considered when ultrasonographically, a sharply marginated, anechoic mass immediately caudal to the right kidney, ipsilateral hydroureter and hydronephrosis were detected. Extravasation of contrast medium was not seen during excretory urography. A fluid-filled retroperitoneal mass adjacent to a transected ureter was found at exploratory laparotomy. The diagnosis of urinoma (para-ureteral pseudocyst) and hydronephrosis was confirmed histopathologically.  相似文献

Congenital anomalies in horses are very rare, and contracted foal syndrome is one of the most commonly reported. This malformation is characterized by contraction of the joints of the forelimbs and/or hindlimbs. In addition, the syndrome can be characterized by vertebral column malformations, such as scoliosis or torticollis, and cranial deformity. The present report describes the radiological and necroscopical findings of multiple rare malformations in two foals. Both foals showed skeletal abnormalities and fenestration of the abdominal cavity. Other pathological findings include a interventricular septal defect in one and a unilateral hydronephrosis and partial hydroureter in the other foal. Although in this report a specific aetiology could not be provided, insecticides treatment provided during the second month of pregnancy might play a role in the pathogenesis of these malformations.  相似文献

A two-year-old chihuahua bitch was presented with urinary incontinence following ovariohysterectomy which had been performed at the time of caesarean section. Clinical, contrast radiographic and surgical investigation revealed the presence of right hydroureter and hydronephrosis, vesicovaginal fistula and absence of most of the urinary bladder. These abnormalities appeared to have resulted from ligation of the caudal bladder, at the level of the trigone, during ovariohysterectomy.  相似文献

A 3-month-old, Labrador bitch presented with urinary incontinence. A unilateral, ectopic ureter was diagnosed with ultrasound without the aid of additional contrast radiographic techniques. Ipsilateral hydroureter and mild hydronephrosis were also present. At the level of the bladder trigone the ectopic ureter became intramural and this was clearly demonstrable with ultrasound. The opening of the ectopic ureter into the proximal urethra was, however, not visualised owing to its intrapelvic location.  相似文献

Urinary diversion by transplantation of both ureters into a reservoir constructed from 60 cm of jejunum was performed in six clinically normal dogs. The reservoir was connected to a stoma on the abdominal wall through a valve constructed from a short segment of intussuscepted bowel to provide continence. The reservoir was emptied three times daily by catheterization. One dog did not survive the surgical procedure and two dogs died within 1 week of surgical complications. The postoperative capacity of the reservoir in surviving dogs was 100 to 200 mL; it increased during the first month to 600 to 750 mL. Continence was excellent in two dogs. One dog was continent until month 2, when partial slippage of the intussusception occurred. A reversible hyponatremic, hypochloremic, hypokalemic metabolic acidosis developed. Bacteriuria was not responsive to systemic or local instillation of antibiotics. Ascending pyelonephritis, hydroureter, and hydronephrosis occurred in two dogs. Struvite urinary calculi formed in one dog. The procedure as described would be unsuitable for clinical use in dogs.  相似文献

A ureteral sarcoma was diagnosed in a nine-year-old Weimaraner dog with gross haematuria, severe unilateral hydronephrosis, and hydroureter. Treatment consisted of unilateral nephrectomy and ureterectomy. This case was compared with 14 other ureteral tumours reported in the veterinary literature. Only three previous reports concerned a malignant ureteral tumour. Urinary tract neoplasms mainly involve the bladder and the kidney, and more rarely the urethra. The purpose of this paper is to report a rare case of malignant ureteral tumour in a dog.  相似文献
