PRIMARY neoplasms of the lower urinary tract of the dog are relatively uncommon. These neoplasms occur most frequently in older dogs and, while they can originate anywhere along the urinary tract, the urinary bladder is by far the most common site. Reports in the literature indicate that neoplasms of the urinary bladder account for approximately 0.5% of all tumors in dogs.1  相似文献

Intraoperative Irradiation of 16 Spontaneously Occurring Canine Neoplasms   总被引：1，自引：1，他引：0  
Sixteen dogs with malignant neoplasms were treated with intraoperative radiation therapy after surgical debulking. Fractionated external beam radiation therapy was given postoperatively to 11 dogs. Healing of surgical incisions was uncomplicated in 14 dogs. When the ureters or urinary bladder were included in the irradiation field, they became stenotic and fibrotic. Urinary incontinence and secondary renal injury were common. Local tumor control was poor regardless of site or tumor type.  相似文献

Evaluation of histologic data obtained from 90 breeds of dogs with 3,837 neoplasms collected over 10 years (1961-1971) revealed 21 cases of urinary bladder neoplasmia in 14 breeds of dogs. There was no breed predispostion. The mean age of dogs with urinary bladder neoplasia was 9.5 years; 6 were males, 13 were females, and 2 were spayed females.  相似文献

Between Jan 1, 1981, and June 30, 1985, fibromas were diagnosed in tissues removed from the urinary bladders of 51 dogs. Hematuria, the most common clinical sign, was associated with the fibromas in 47 of 50 cases. Most dogs responded well to surgical excision of the neoplasms, with rapid resolution of the hematuria followed by long periods without abnormal clinical signs. Three dogs were euthanatized because of continuing or recurrent clinical problems, which included bladder dysfunction. One dog required continuing medication with antibiotics and corticosteroids to control hematuria.  相似文献

The aim of the study was to estimate the prevalence and localization of different tumors in the urogenital system in dogs and cats in relation to sex, age and breed of animals. The study was performed on tumors or tissue specimens from tumors of the urinary and genital system obtained during surgery from dogs and cats submitted to the Division of Pathological Anatomy, Department of Clinical Sciences Agricultural University of Warsaw from 1998 to 2005. Most tumors of the urogenital system recognized in the present study derived from dogs (94.20%, 130 cases), and only a few cases were obtained from cats (5.79%). Occurrence and localization of urogenital system tumors in present review is similar to findings reported by other authors. Testicular tumors in males, ovarian lesions in females and urinary bladder tumors in both sexes were most commonly recognized. Older dogs were most often affected, animals with nonmalignant tumors were a bit younger than those with malignant lesions. Any obvious breed predilections were found, but terriers were at increased risk for development of transitional cell carcinoma of the urinary bladder and mixed breed and German shepherd for development of testicular neoplasms.  相似文献

One hundred and fifteen dogs with neoplasms of the lower urinary tract (bladder and/or urethra) were retrospectively evaluated at five referral institutions participating in ongoing studies by the Veterinary Cooperative Oncology Group. Most tumors were malignant (97%) and of epithelial origin (97%). Lower urinary tract tumors were more common in older dogs weighing greater than 10 kg. The following significant (P less than 0.05) statistical associations were found using the University of Guelph hospital population as control; there was no sex predisposition although the female:male ratio was 1.95:1. Neutered dogs were predisposed as were Airedale Terriers, Beagles, and Scottish Terriers, whereas German Shepherds were significantly under-represented among dogs with lower urinary tract tumors. These statistical associations should be interpreted cautiously because of possible demographic differences in hospital populations among the University of Guelph and other cooperating institutions. There were no significant correlations between age, gender, weight, breed, response to therapy, and survival time. Clinical signs were indicative of lower urinary tract disease and included hematuria, stranguria, and pollakiuria. The laboratory data were nonspecific except for urinalysis test results. Hematuria and inflammatory urinary sediments were most commonly reported; neoplastic cells were identified in the urine sediment of 30% of dogs with lower urinary tract tumors. Contrast cystography was a useful noninvasive diagnostic method since 96% of the dogs had a mass or filling defect in the lower urinary tract demonstrated by this technique.(ABSTRACT TRUNCATED AT 250 WORDS)  相似文献

Disorders of the urinary system are common in geriatric dogs. Common urinary disorders that are seen in older dogs include chronic renal failure, urinary incontinence, bladder tumors, and prostate problems. Therapy for chronic renal failure is aimed at both slowing the progression of the disease and ameliorating the signs of uremia. Therapeutic recommendations for the conservative medical management of chronic renal failure include reducing dietary protein, moderately reducing salt intake, maintaining normal serum phosphorus levels, providing free access to water, avoiding stress, supplementing water soluble vitamins, using anabolic steroids to treat the anemia of chronic renal failure, treating acidosis, and controlling hypocalcemia. Urinary incontinence can often be controlled or eliminated. The appropriate approach to management of this disorder is to identify and remove specific causes. Common causes of urinary incontinence are urethral incompetence, urinary tract infection, and polyuria and polydypsia. Bladder tumors are, fortunately, not a common tumor of dogs, but are more common in geriatric dogs than in the young. The most common bladder tumor is the transitional cell carcinoma. Therapy for this tumor is usually palliative because of its malignant nature and because it is usually located in the neck of the bladder. Its location in the bladder often makes it impossible to resect the tumor completely without removing the entire bladder and diverting the ureters. New chemotherapeutic modalities are being evaluated that may increase life expectancy after diagnosis and, therefore, improve prognosis. Prostate disease is also seen in older dogs. Types of prostate abnormalities seen in dogs include prostatic hyperplasia, cysts, abscesses, acute and chronic infection, and neoplasia. The institution of proper therapy requires an accurate diagnosis; neutering is often recommended as a part of therapy regardless of the type of prostatic disease present.  相似文献

Urinary tract infection (UTI) was induced in the left kidney of seven female dogs and in the urinary bladder of eight female dogs. Several methods advocated for localization of UTI in other species were tested in the infected dogs. Although fever, renal pain, and leukocytosis were detected in some dogs with renal infection, findings were transient. Radiographic changes in the kidneys and ureters were detected in some dogs with renal infection, but were absent in others. Bladder washout studies were not reliable for differentiating renal infection from bladder infection. Antibody coating studies were positive in dogs with bladder infection and in dogs with renal infection. The positive results from dogs with bladder infection may have been because of nonspecific binding of immunoglobulins to Staphylococcus aureus after leakage of serum immunoglobulins into urine. Studies of six dogs of both sexes with naturally occurring UTI indicated that their serum contained antibody against common urinary pathogens and that this antibody gained access to the urine in some dogs. It was concluded that the antibody coating test was unreliable for localization of UTI in the dog.  相似文献

Normal cats (n = 38) and dogs (n = 40) were imaged with fundamental ultrasound and tissue harmonic ultrasound. Images of the liver, gall bladder, spleen, left kidney, urinary bladder, and jejunum were collected in all animals. Images of the left adrenal gland were collected in all dogs. All normal cats and dogs had improved imaging with tissue harmonic ultrasound. The number of organs with improved conspicuity ranged from one to all organs imaged. The most common organ to have improved conspicuity was the jejunum (100% of dogs and 89% of cats). Significant improvement by tissue harmonic ultrasound was seen in images of gall bladder (p = .05) and left adrenal gland (p = .02) in dogs, and spleen, urinary bladder, and intestinal images (p = .01) in cats. Significant improvement was seen in tissue harmonic ultrasound images of the gall bladder in dogs weighing greater than 16 kilograms (p = .03) and in the images of the urinary bladder of dogs weighing less than 16 kilograms (p = .02). These data suggest that image quality improvement of normal organs using tissue harmonic ultrasound is consistent but not predictable. The exception was the jejunum, where improvement was seen in all dogs. Sonographers should be cognizant of the potential benefits of tissue harmonic ultrasound.  相似文献

Neoplasia of the equine urinary bladder as a cause of hematuria   总被引：1，自引：0，他引：1  
In 6 horses with urinary bladder neoplasms, common clinical findings included a palpable mass in the bladder, anemia, hematuria, and/or proteinuria. Squamous cell carcinoma was found in 4 horses and appears to be the most common bladder tumor in the horse. Single cases of transitional cell carcinoma and fibromatous polyp also were identified. All horses except one were over 10 years of age. In one mare, treatment with 5-fluorouracil intracystically resulted in decreased bleeding from the bladder mass and apparent stabilization of the mass size. The mare ultimately died because of abdominal metastasis. Although rare, neoplasia of the urinary bladder should be considered when evaluating horses with hematuria.  相似文献

Urine from 237 dogs submitted for euthanasia was collected directly by needle aspiration from the urinary bladder. The bacteriological findings were correlated with the sex and age of the dogs. E. coli was the most frequent species found. The overall incidence of bladder infection was 6–2% for males and 26–6% for females. Bladder infection can be categorized on the basis of occurrence in either very young or in older dogs. The infection incidence increased linearly in bitches older than 4 years, ending at a 50% frequency in those more than 10 years old. Pyometra frequency also increased after 4 years of age and this pattern may indicate a common causative factor for urinary tract infection and pyometra. This investigation shows that subclinical urinary tract infection is common in dogs and is related to age in bitches.  相似文献

OBJECTIVE-To identify the most common cutaneous neoplasms in dogs and evaluate breed and age distributions for selected neoplasms. DESIGN-Retrospective epidemiological study. SAMPLE-Records available through the Veterinary Medical Database of dogs examined at veterinary teaching hospitals in North America between 1964 and 2002. PROCEDURES-Information on tumor type and patient breed and age was collected. Incidence and odds ratios with 95% confidence intervals were calculated. RESULTS-Records of 1,139,616 dogs were reviewed. Cutaneous neoplasms were diagnosed in 25,996 of these dogs; records for the remaining 1,113,620 dogs did not indicate that cutaneous neoplasms had been diagnosed, and these dogs were considered controls. The most frequent age range for dogs with cutaneous neoplasms was 10 to 15 years. Lipoma, adenoma, and mast cell tumor were the most common skin tumor types. CONCLUSIONS AND CLINICAL RELEVANCE-Results supported previously reported data regarding cutaneous neoplasia in dogs but provided updated information on the most common skin tumors and on age and breed distributions.  相似文献

INTRAOPERATIVE RADIOTHERAPY OF CANINE BLADDER CANCER   总被引：2，自引：0，他引：2  
Thirteen dogs had partial surgical extirpation followed by whole bladder intraoperative radiotherapy for urinary bladder cancer. Eleven of the neoplasms were transitional cell carcinomas (five Stage T1, six stage T2); one was rhabdomyosarcoma (Stage T2), and one was leiomyosarcoma (Stage T2). Histopathologic evaluation showed that neoplasia extended to the margins of the excised tissue in at least 11 of the 13 dogs. Radiotherapy from a 137Cs teletherapy machine was applied to the surgically exteriorized bladder, with doses at the 90% isodose level varying from 2188 to 2888 cGy (10 of 13 dogs receiving 2670–2700 cGy). Sixty-one percent of the dogs were alive at 1 year, 30% at 18 months, and 15% at 2 years. From the time of initial clinical signs of bladder neoplasia, 69% of the irradiated dogs were alive at 1 year, 46% at 18 months, and 23% at 2 years (one dog is still living, at 70 months). Of the owner-reported or clinically determined posttherapy complications, there was increased frequency of urination in 46% of the dogs, urinary incontinence in 46%, cystitis in 38%, and stranguria in 15%. Either persistence or recurrence of neoplasia was found in six (46%) of the dogs and metastasis in four (30%), with two of these having both recurrence and metastasis. Qualitative assessment of the complications was not done, but owner-perceived severity of the complications, metastasis, or diagnosed persistence or recurrence of the neoplasm were the major reasons for ultimately killing most of the dogs.  相似文献

Evaluation of the anatomic location of the distended and empty urinary bladders and urethras of healthy adult male and female dogs and cats by retrograde urethrocystography revealed substantial variations. In 15 dogs in lateral recumbency with empty bladder lumens, the caudal portion of the urinary bladder was within the pelvic canal in 5 of 7 male and 5 of 8 female dogs. In female dogs examined in ventrodorsal recumbency, only 4 of 8 had the empty urinary bladders in part within the pelvic canal. After luminal distention, 3 of 7 male and 3 of 8 female dogs, while in lateral recumbency, had the urinary bladders in part intrapelvically. However, when female dogs were placed in ventrodorsal recumbency, only 1 of 7 urinary bladders was in part within the pelvis. The urinary bladders of 14 cats were consistently within the abdominal cavity, irrespective of whether the bladder lumen was distended or empty. Urethral flexures occurred in dogs with intrapelvic bladders that were distended or empty. Urethral flexures were not found in cats. The urethras of dogs and cats in lateral recumbency were generally closer to the floor of the pelvis after urinary bladder distention than when the bladder was empty. The urethra of the dogs and cats in ventrodorsal recumbency was to the left or right of or on the midsagittal plane, whether the urinary bladder was empty or distended. A greater degree of lateral displacement was encountered in ventrodorsal recumbency after urinary bladder distention.  相似文献

The occurrence of postoperative adhesions following ventral (20 dogs) or dorsal (12 dogs) urinary bladder incisions was evaluated. The bladder incisions were sutured with 3–0 polydioxanone suture material in a two-layer closure. Laparotomy (no urinary bladder incision) was performed in four dogs, which served as controls. The surgical sites were examined 1 (30 dogs) and 2 weeks (6 dogs) after surgery. Omental adherence to the urinary bladder was a frequent finding, but none of the urinary bladders was adhered to the ventral abdominal wall incision.  相似文献

The clinical, laboratory, and radiographic characteristics of polypoid cystitis in 2 dogs were similar to those commonly associated with neoplasms of the urinary bladder. Gross appearance of the polyps did not permit differentiation between inflammation and neoplasia; microscopic examination of excised tissue was required to establish a definitive diagnosis. Following surgical extirpation of the polyps, remission of clinical signs was induced by prolonged antibacterial therapy.  相似文献

Urinary incontinence was associated with an ectopic ureter in a 5-month-old, male Wire Fox Terrier. The dog regained urinary continence after transplantation of the ureter from the urethra into the urinary bladder. Of the 3 reported cases of extopic ureters in male dogs, 2 have been associated with urinary incontinence. These observations do not support the hypothesis that ectopic ureters are more frequently recognized in female than in male dogs because urinary incontinence is more commonly associated with the disorder in female dogs.  相似文献

OBJECTIVE: To identify clinical features of Corynebacterium urealyticum urinary tract infection in dogs and cats and antimicrobial susceptibility patterns of C urealyticum isolates. DESIGN: Retrospective study. ANIMALS: 5 dogs and 2 cats. PROCEDURE: Medical records of dogs and cats for which C urealyticum was isolated from urine samples were reviewed. Isolates from clinical cases, along with previously lyophilized unsubtyped isolates of Corynebacterium spp collected between 1977 and 1995, were examined and, if subtyped as C urealyticum, tested for antimicrobial susceptibility. RESULTS: Signalment of infected animals was variable. Prior micturition disorders were common, and all animals had signs of lower urinary tract disease at the time C urealyticum infection was diagnosed. Median urine pH was 8.0; WBCs and bacteria were variably seen in urine sediment. In vitro antimicrobial susceptibility testing of 14 C urealyticum isolates revealed that all were susceptible or had intermediate susceptibility to chloramphenicol, tetracycline, and vancomycin and most were susceptible to enrofloxacin. Thickening of the bladder wall and accumulation of sediment were common ultrasonographic findings. Contrast radiography or cystoscopy revealed findings consistent with encrusting cystitis in 3 dogs. Infection resolved in 2 dogs following surgical debridement of bladder plaques and antimicrobial administration. In 2 other dogs and 1 cat treated with antimicrobials, infection with C urealyticum resolved, but urinary tract infection with a different bacterial species developed. CONCLUSIONS AND CLINICAL RELEVANCE: Results suggest that preexisting urinary tract disorders are common in dogs and cats with C urealyticum infection. Treatment with appropriate antimicrobials in combination with surgical debridement might eliminate C urealyticum infection.  相似文献

Background: Electrohydraulic lithotripsy (EHL) has been used as an alternative to cystotomy in human medicine to remove urinary calculi. This prospective study evaluated the efficacy and safety of EHL to remove urinary calculi in dogs. Hypothesis: EHL is an efficient and safe method of treatment of bladder and urethral calculi in dogs. Methods: Dogs presented between January 1, 2005 and June 1, 2007 with lower urinary tract calculi diagnosed by radiographs or ultrasound examination were included in the study. Physical examination, CBC, biochemistry, urinalysis, and urine culture were performed at presentation. EHL and voiding urohydropulsion were performed under general anesthesia. Patients received IV fluids for 12 hours after which they were rechecked by ultrasound examination and discharged with antibiotics and anti‐inflammatory drugs for 5 days. All patients were reevaluated 1, 3, and 6 months after presentation by physical examination, urinalysis, and ultrasonography. Results: Twenty‐eight dogs (19 males, 9 females) presented with bladder or urethral calculi or both underwent lithotripsy. Their median weight was 8.3 kg. Calcium oxalate calculi were present in 22 dogs, struvite in 4, and mixed calculi in 2. Fragmentation was done in the bladder (23 dogs) and in the urethra (12 dogs). Calculus‐free rate was higher for urethral than for bladder calculi in males and higher for bladder calculi in females than in males. No major complications were reported. Twelve dogs relapsed within 6 months. Conclusions: Results of this study support the use of EHL as a minimally invasive treatment for bladder calculi in females and for urethral calculi in male dogs.  相似文献
