Urethral obstruction in a male llama 总被引：1，自引：0，他引：1
B G McLaughlin N C Evans 《Journal of the American Veterinary Medical Association》1989,195(11):1601-1602
An 8-year-old sexually intact male llama was euthanatized because of obstruction of the penile portion of the urethra and rupture of the urinary bladder. Clinical signs of obstruction included anorexia, lethargy, teeth grinding, straining to defecate, inability to urinate, and tense abdomen. Laboratory findings included anemia, leukocytosis with left shift, high serum urea nitrogen, creatinine, and phosphorus concentrations, and low serum chloride concentration. Necropsy revealed ruptured urinary bladder and acute fibrinous peritonitis. A firm, gray, nonmineralized urethral plug occluded the penile portion of the urethra for a distance of 14 cm in the midpenile region, distal to the sigmoid flexure of the penis. The urinary bladder mucosa and the urethra had microscopic evidence of chronic inflammation. Escherichia coli, Klebsiella sp, and alpha-streptococci were isolated from the urethral plug. 相似文献

Metabolic changes were studied in the serum, saliva and peritoneal fluid of 5 healthy yearling feedlot steers after experimentally induced urinary bladder rupture. There were statistically significant decreases in serum, saliva and peritoneal fluid sodium and chloride values and significant increases in serum, saliva and peritoneal fluid urea nitrogen, creatinine and phosphorus values. Serum calcium, pH, bicarbonate, and base excess decreased significantly. Potassium did not change significantly in serum but did increase significantly in the saliva. The hemogram and peritoneal fluid analysis failed to provide clinicopathologic evidence of peritonitis. The average time of death or euthanasia after bladder rupture was 13.6 days with a range of 8-21 days. No single biochemical parameter could be identified which would allow prediction of the approaching time of death or duration of the disease process. There was no peritonitis at necropsy indicating that urine was not irritating to the bovine peritoneal cavity. Extracellular replacement fluid with or without sodium bicarbonate supplementation appeared to be the fluid of choice for correction of fluid and electrolyte imbalances in steers with ruptured urinary bladders. The ratio between serum and peritoneal fluid creatinine concentrations appears to be valuable for the clinical diagnosis of ruptured urinary bladders in steers. 相似文献

Squamous cell carcinoma (SCC) is the most common external genital neoplasm. Early detection, diagnosis and treatment are paramount to successful outcome; overlooked or misdiagnosed SCC can rapidly invade tissues and metastasise, producing potentially fatal complications. This report describes a case of overlooked SCC that resulted in severe penile infiltration, urethral stricture, and subsequent urinary bladder rupture and peritonitis. 相似文献

A case of peritoneal sclerosing mesothelioma in a 3-year-old German shepherd dog is reported. The dog presented a severe abdominal distension. Cytological examination of the peritoneal fluid revealed anaplastic epithelioid cells. Necropsy findings revealed an irregular-shaped mass attached to the pancreas and stomach with numerous nodules covering the intestinal and urinary bladder serosa. The diagnosis was made by histology and immunohistochemistry, with cytokeratin, vimentin and calretinin antibodies. Differential diagnosis with chronic peritonitis and spreading of abdominal primary carcinoma is discussed. 相似文献

A 14-month-old female dog, Gos d'Atura Catala was presented for a 7-month-history of reoccurring urinary tract infection. Using sonography, a focal multilobulated thickening of the urinary bladder wall was discovered. The solid mass was arising from the area of the ureteral papllDae and bulging into the lumen of the bladder neck. The wall of the urethra was uniformly thickened. These findings were not considered typical for a generalized urinary tract infection but more indicative of local severe inflammation, neoplasia or hyperplasia in the area of the ureteral openings. The thickening of the urethra was suggestive of urethritis or neoplastic infiltration. Signs of metastasis were not detected on the thoracic radiographs or in the remainder of the abdominal ultrasound examination. A surgical excision of the multilobulated mass was performed and histologic examination was conducted. A fibrosarcoma in the lamina propria of the urinary bladder wall was diagnosed. Because of reoccurence of hematuria and unresponsiveness to therapy the dog was euthanized. Postmortem examination confirmed the diagnosis of fiborsarcoma in the urinary bladder. Additionally, neoplastic infiltration of the urethral wall and metastasis in the lungs and liver were detected histopathologically. 相似文献

A two-year-old, castrated male Main Coon cat was referred because of chronic, recurrent pollakiuria, haematuria, and acute vomiting. On clinical examination, a smooth, soft-tissue mass, suspected to be the urinary bladder, was palpable outside of the abdominal wall in the inguinal area. On radiographs, the urinary bladder was found to be extra-abdominal, and herniated through an enlarged right inguinal canal at exploratory coeliotomy.The left inguinal canal was also enlarged. The urinary bladder was repositioned and fixed to the caudal abdominal wall by incisional cystopexy and both enlarged inguinal canals were partially closed with an interrupted suture pattern. 相似文献

CASE DESCRIPTION: A 5-year-old Labrador Retriever was evaluated because of a 3-day history of lethargy, anorexia, vomiting, stranguria, and anuria after routine ovariohysterectomy. CLINICAL FINDINGS: On initial examination, signs of abdominal pain and enlargement of the urinary bladder were detected. Clinicopathologic abnormalities included leukocytosis, azotemia, and hyperkalemia. Radiography and surgical exploration of the abdomen revealed urinary bladder torsion at the level of the trigone; histologically, there was necrosis of 90% of the organ. TREATMENT AND OUTCOME: After excision of the necrotic wall of the urinary bladder (approx 0.5 cm cranial to the ureteral orifices), the remaining bladder stump was closed with a colonic seromuscular patch. Eleven weeks later, cystoscopy revealed an intramural ureteral stricture, for which treatment included a mucosal apposition neoureterocystostomy. Thirteen months after the first surgery, the dog developed pyelonephritis, which was successfully treated. By 3 months after subtotal cystectomy, the dog's urinary bladder was almost normal in size. Frequency of urination decreased from 3 to 4 urinations/h immediately after surgery to once every 3 hours after 2 months; approximately 4 months after the subtotal cystectomy, urination frequency was considered close to normal. CLINICAL RELEVANCE: Urinary bladder torsion is a surgical emergency in dogs. Ischemia of the urinary bladder wall may result from strangulation of the arterial and venous blood supply and from overdistension. Subtotal resection of the urinary bladder, preserving only the trigone area and the ureteral openings, and colonic seromuscular augmentation can be used to successfully treat urinary bladder torsion in dogs. 相似文献

A six‐year‐old neutered female albino ferret was presented with an acute episode of lethargy and anorexia. Clinical examination revealed marked cranial abdominal pain. A severe neutrophilic leukocytosis was present. Abdominal ultrasound was consistent with a diffuse peritonitis and severe bile duct inflammation. Cytology of the abdominal effusion revealed bile peritonitis. An exploratory laparotomy was performed and the gall bladder appeared inflamed with multiple perforations. A cholecystectomy was performed. The ferret recovered without complication. Bacteriological culture of the bile and gall bladder yielded a pure growth of Pseudomonas aeruginosa. Histopathological analysis of the gall bladder and liver was consistent with a marked cholecystitis and cholangiohepatitis. On the basis of sensitivity testing, the ferret was treated with marbofloxacin for one month. No complications or reoccurrence were seen up to 1 year after the diagnosis. To the author's knowledge, this is the first report of bile peritonitis secondary to gall bladder rupture in a ferret. 相似文献

A 14-year-old spayed female poodle-pekinese dog with a history of hematuria was tentatively diagnosed with non-radiopaque uroliths or urinary bladder neoplasia following temporary resolution of clinical signs after several rounds of antibiotic treatments, normal abdominal radiographs and no growth on urine culture. Abdominal ultrasound revealed a mass in the trigone area of the urinary bladder which was confirmed to be an invasive transitional cell carcinoma by histopathology following euthanasia. 相似文献

A 5-year-old guinea pig with suspected urolithiasis was presented for radiology and ultrasound examinations of the abdomen. Radiographically, an irregular-shaped mineral opacity was detected in the area of the urinary bladder. Ultrasonographically, pyelectasia of the right kidney, hydroureter with an ureterolith cranial to a thickened ureter wall close to the ureterovesical junction, and a thickened urinary bladder wall were detected. Histopathologically, the thickened ureter wall was found to be a papilloma. The ureter calculus consisted of 100% calcite. 相似文献

An 8-year-old intact male dwarf rabbit (Oryctolagus cuniculus) was presented with a 2-month history of unilateral scrotal swelling. The external physical examination of the rabbit patient confirmed the severe, unilateral, fluid-filled scrotal distention. Radiographic images of the effected scrotum revealed a soft tissue swelling in the area of the left testicle, and the absence of the urinary bladder in the caudal abdomen. Ultrasonography verified the presence of a fluid-filled mass in the scrotum, enveloping the left testicle. A fine-needle aspiration of the scrotal mass yielded urine, thus a diagnosis of a nonreducible herniation of the urinary bladder into the scrotum was made. An inguinal herniorrhaphy was performed, and the bladder was successfully reduced into the abdominal cavity. A bilateral routine castration and left scrotal ablation were also performed. Two months after surgery no recurrence was noted, and the patient had normal urinary function. Inguino-scrotal bladder herniation is rare in both humans and animals. Male rabbits are predisposed to inguinal and scrotal hernias because their inguinal rings remain open throughout life. Herniation of the urinary bladder should be considered as a differential diagnosis when intact male rabbits are presented with unilateral scrotal swelling. 相似文献

OBJECTIVE-To evaluate a laparoscopic technique for implantation of a urinary catheter in the right paramedian area in male sheep and to determine feasibility, benefits, and risks for this technique. DESIGN-Evaluation study. ANIMALS-6 Healthy male sheep (mean +/- SD body weight, 42.16 +/- 11.95 kg [92.75 +/- 26.29 lb]). PROCEDURES-Each sheep was anesthetized and positioned in dorsal recumbency. A 10-mm laparoscope was inserted in the right paramedian area between the xiphoid and preputial orifice. After creation of capnoperitoneum, grasping forceps were inserted in the left paramedian area at the level of the teats and used to immobilize the urinary bladder. A pigtail balloon catheter was implanted transcutaneously in the right paramedian area between the preputial orifice and teats and directed into the urinary bladder by use of laparoscopic guidance. The catheter was removed 10 days after implantation. Fourteen days after initial surgery, a second laparoscopy was performed to evaluate pathologic changes. RESULTS-Inadvertent insertion of the first trocar into the rumen of 1 sheep was the only intraoperative complication encountered. Laparoscopic-assisted implantation of the urinary catheter was successfully performed in all sheep. No postoperative complications were detected. CONCLUSIONS AND CLINICAL RELEVANCE-Laparoscopic-assisted implantation of a urinary catheter in the right paramedian area was successfully performed and may be a feasible method for use in sheep. This method can be considered as an alternative to tube cystotomy performed by laparotomy. 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

Because the abdomen of the adult horse is too thick to obtain good-quality radiographs, diagnostic ultrasound is a particularly valuable imaging modality in the diagnosis of abdominal disease. The size, shape, position, and texture of the liver, spleen, kidneys, urinary bladder, gravid uterus, and gut wall can be determined by scanning the abdominal surface. The presence or absence of abdominal fluid can be determined efficiently. Gut motility as well as ileus secondary to peritonitis or obstruction can be assessed. Suspected adhesions of the bowel can often be documented, and primary or secondary neoplastic processes can be identified and biopsied. 相似文献

A transitional cell carcinoma of the urinary bladder was found in a beluga whale stranded in the St. Lawrence middle estuary. Various organs of this animal were submitted to high resolution gas chromatography coupled with mass spectrometry analysis. High frequency of urinary bladder cancer in the human population of the same area and the presence of carcinogenic compounds in the marine environment of this animal are discussed.
Concurrent isolation of Edwardsiella tarda from various organs of this whale is also reported.

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 case of feline rectal prolapse which appeared to be secondary to transitional cell carcinoma of the urinary bladder is described. The cat was reported to be incontinent and treatment was declined by the owners. Euthanasia was performed and necropsy revealed an extensive nodular thickening of the entire urinary bladder wall. A diagnosis of urinary bladder transitional cell carcinoma was made on histopathological examination. 相似文献

A 9-year-old, quarter horse gelding with obstructive urethrolithiasis was treated with a perineal urethrostomy. The horse's condition deteriorated and abdominocentesis confirmed septic uroperitonitis. The horse was euthanized and postmortem examination revealed peritonitis, a tear in the lateral wall of the bladder, and a nephrolith within the left renal pelvis. 相似文献
