Cases of paraphimosis are rarely described in ferrets. Phimosis has not been reported in the ferret. Two castrated ferrets with abnormalities of the prepuce were presented separately. Case 1 had a 4-month duration of a non-reducible paraphimosis. A shortening of the sheath prevented complete covering of the penis. Case 2 had dermatitis around the prepuce of a month's duration. The foreskin was distended by urine which could be eliminated through a barely visible opening by the application of manual pressure. The penis could not be extruded under general anesthesia. Surgery was performed in both cases. In case 1, parts of the skin of the prepuce, and mucosa of the sheath were resected to create an enlarged opening correcting the constriction of the penis. In case 2, a circular incision was made along the periphery of the skin with dermatitis, and the skin of the prepuce. The skin was resected to enlarge the preputial orifice. Surgical treatment was successful in both cases, did not present any technical difficulties, and was of a short duration. Surgical treatment of paraphimosis and phimosis have not been reported in ferrets and should be considered in cases of scalding of the prepuce not responding to medical treatments.  相似文献

CASE DESCRIPTION: A 6-year-old castrated male Shih Tzu was evaluated because of intermittent bleeding during urination. CLINICAL FINDINGS: Necrosis of the cranial portion of the penile shaft extended distally from the preputial fornix. Penile necrosis secondary to strangulation from paraphimosis was diagnosed. TREATMENT AND OUTCOME: A midline preputiotomy incision was used to expose the penile shaft; amputation was performed caudal to the preputial fornix. The terminal portion of the urethra was anastomosed to the preputial mucosa, which allowed the dog to urinate through the preputial orifice. CLINICAL RELEVANCE: Unlike the more conventional urethrostomy procedures performed in dogs, preputial urethrostomy eliminates the potential for local skin irritation during urination. Preputial urethrostomy is also easier to perform in those dogs in which penile amputation is required adjacent to the preputial fornix. A release incision cranial to the prepuce can be used to facilitate caudal displacement of the preputial mucosa, which facilitates urethral anastomosis to this structure. A midline preputiotomy incision provided excellent exposure of the penile shaft for this surgical procedure.  相似文献

An eight-week-old male Boston terrier presented for penile desiccation and urine pooling in the prepuce due to congenital hypospadias. An advancement flap was created from the dorsal mucosa of the incompletely formed prepuce and sutured circumferentially to construct a longer distal preputial mucosa. V- to Y-plasty of the ventral abdominal skin was utilised to create the preputial skin overlying the mucosal flap. Urethrostomy and partial penile amputation were also performed. Following surgery, the clinical signs of penile desiccation and preputial urine pooling resolved and acceptable cosmetic appearance was achieved. This technique may be considered for glandular or penile hypospadias or following resection of the ventral aspect of the distal prepuce when inadequate tissue is present for a simple two-layer closure of the preputial mucosa and skin.  相似文献

A preputial foreign body caused severe preputial swelling and depression in a 4-year-old Shorthorn bull. Disruption of the preputial epithelium by the foreign body resulted in abscess formation lateral to the prepuce. A patent urethral fistula, probably a complication of prior fibropapilloma excisional surgery, was also detected on the distal portion of the glans penis. Foreign body removal, antimicrobial administration, and warm hydrotherapy resolved the swelling and abscess. Electroejaculation was used to extend the penis and to minimize preputial adhesions. Breeding soundness examinations were used to evaluate breeding potential.  相似文献

OBJECTIVE: To compare sensitivity for diagnosing Tritrichomonas foetus infection in bulls using 2 sampling tools and to calculate negative predictive values for infection. DESIGN: Randomized clinical trial. ANIMALS: 30 Bos taurus bulls naturally or experimentally infected with T foetus. PROCEDURE: Preputial scrapings were obtained once/wk for 6 weeks using an artificial insemination pipette and a metal brush; which tool was used first for each bull was randomly determined. Samples were collected first from the left side of the prepuce and then from the right side and placed in commercially available transport media chi 2 Values and confidence limits were adjusted for effect of clustering of results by bull. RESULTS: Significant differences in sensitivity of results were not found between samples collected using the brush or pipette. Using the pipette, sensitivity was estimated to be 91.6% (95% confidence interval, 84.3 to 95.7%); negative predictive values ranged from 41 to 99% for prevalence of infection of 90 to 5%, respectively. Sensitivity was 88.8% for first sample obtained and 96.1% for second sample obtained. CONCLUSIONS AND CLINICAL RELEVANCE: Collection of preputial scrapings with an artificial insemination pipette or a metal brush and use of a commercially available culture system can provide a sensitive diagnostic test for T foetus infection in bulls. Calculated negative predictive values indicated that 1 or 2 tests would suffice in most clinical situations. For bulls from herds in which T foetus is endemic, 2 to 4 tests/bull may be required to ensure that each bull is not infected.  相似文献

Causes of copulatory failure in beef bulls   总被引：1，自引：0，他引：1  
A cow in full standing estrus is required to assess a bull's ability to copulate. Insufficient libido is not involved if the bull sniffs the cow's vulva and attempts to mount. Blood or pus exiting the penis or prepuce indicates penile or preputial lacerations or other lesions. Rear foot or stifle lesions, seminal vesiculitis, traumatic reticulitis or lumbar spinal injuries may prevent the bull from mounting. Preputial stenosis, penile adhesions, desensitization, hematomas or deviations, peripreputial abscess, cavernosal shunts, insufficient penile length and occlusions of the cavernosal canals may prevent intromission after mounting.  相似文献

: This clinical case report described a three-month-old mongrel dog that had the urethral orifice opening 3 cm from the tip of the penis and lacked a completely formed preputial sheath. It was presented to the clinic with an exposed penile shaft that was dry. The dog had urinary incontinence that was not of neurological origin. It also had unilateral agenesis of the right testicle. The preputial sheath was successfully reconstructed. Urinary incontinence stopped soon after surgery, suggesting that it had been probably due to an ascending urethritis. A large preputial opening was left because of the location of the urethral opening.  相似文献

A 14-year-old male poodle weighing 7.5 kg presented due to complications after preputial urethrostomy for management of preprostatic urethral rupture. Revision surgery was performed with preputial tube-flap urethroplasty via preputiotomy. A longitudinal flap was raised from the prepuce and anastomosed to the end of the previously cut urethra to create a neourethra and reduce tension at the urethrostomy site. Follow-up retrograde positive contrast urethrography performed 10 days and 6 months postoperatively showed no contrast leakage from either the neourethra tube flap or new preputial urethrostomy. A follow-up email questionnaire, based on the American Urological Association Symptom Index, was completed by the owner 6 months after surgery. The dog had excellent symptom scores, and urinated from the prepuce without difficulty in a manner resembling physiological urination.  相似文献

Metastatic transmissible venereal sarcoma in a dog   总被引：1，自引：0，他引：1  
An adult male dog with large penile sheath and serosanguineous exudate from the preputial orifice and a cutaneous fistula in the right inguinal area was examined. Necropsy revealed tumor masses on the penis and prepuce, in superficial inguinal and external iliac lymph nodes, and in the liver. Histopathologic diagnosis of the tumor was confirmed by transplantation studies.  相似文献

A 6-month-old Thoroughbred colt was referred to Rossdales Equine Hospital with a recent history of discomfort and inability to protrude the penis whilst urinating, resulting in accumulation of urine within the prepuce. Careful examination and manual palpation revealed a constrictive ring of fibrous tissue at the level of the preputial orifice. With no evidence of trauma or a persistent penile frenulum, a tentative diagnosis of phimosis due to congenital preputial stenosis was made. Exploratory surgery confirmed the diagnosis and surgical transection and release of the fibromuscular ring at three sites allowed the colt to protrude the penis and urinate normally immediately post-operatively. At follow-up examination 11 months later, the colt continued to be able to extrude the penis and urinate conventionally. A slight excess of skin was present at the end of the prepuce but this was only of minor cosmetic concern.  相似文献

CASE DESCRIPTION: A 2-month-old male degu was treated for preputial damage and lateral penile displacement that occurred during attempted castration. CLINICAL FINDINGS: Bruising and swelling of the prepuce and severe edema to the left of the prepuce were evident. The penis could not be extruded from the prepuce. Radiography revealed a large bladder. Contrast medium injected into the prepuce filled the peripreputial subcutaneous tissues. TREATMENT AND OUTCOME: During surgical exploration through a peripreputial approach, the penis was found to be completely separated from the prepuce and located in the adjacent subcutaneous tissue. The penis was repositioned in the prepuce and anchored with a suture at its base. The following day, the preputial orifice was crusted over, urine was leaking from the incision, and the penis could not be extruded from the prepuce. The anchoring suture was removed, and the tip of the penis was sutured to the preputial orifice so that the penis protruded slightly from the prepuce. Urination was normal after the second surgery. Two years later, the preputial orifice remained adhered to the distal portion of the penis and the exposed penile tissue was healthy. CLINICAL RELEVANCE: Penile displacement from the prepuce is an unusual complication of castration in degus. The surgical technique used in this animal may be an effective means of repair. Permanent exposure of the tip of the penis may be well-tolerated in degus.  相似文献

Two trials were carried out to assess the diagnostic sensitivity and practicability of preputial scraping as a method of collecting preputial material from bulls infected with Tritrichomonas foetus. In the 1st trial, preputial material was collected by simultaneous scraping and aspiration from 3 infected and 1 uninfected bull 10 times over a 5-week period. In the 2nd trial, samples from 5 infected bulls were collected by both sheath washing and scraping on 6 occasions, while 8 uninfected animals were sampled 3 times. Samples were cultured using a modified Trichomonas culture medium (Oxoid). In the first trial, 29 of 30 samples from infected bulls were found to be positive. In the second trial, 83 % of samples collected by both methods tested positive. In neither trial were any samples from the control bulls found to be positive. Scraping was found to be quick and safe, and offered advantages over preputial washing in that urine contamination was easily avoided, samples were smaller and more concentrated and contamination was reduced. It may, however, be subject to greater operator variability than sheath washing. It is concluded that preputial scraping is as effective as washing and represents a suitable alternative for the collection of material for direct examination and culture of Tritrichomonas foetus.  相似文献

A young dog was presented with a history of adopting an unusual posture to urinate, resulting in urine soaking of the ventral abdomen and caudal forelimbs. The dog was initially treated surgically with cranial advancement of the prepuce, which did not resolve the problem. Further surgery was then successfully carried out to create a more caudal preputial orifice, which angled the penis ventrally when extruded, directing urine away from the body. At follow-up clinical examination, the dog was clinically normal.  相似文献

An 11-month-old, intact male Great Pyrenees was presented for recurrent, nonpainful accumulation of suppurative fluid within the prepuce. Surgical exploration revealed a continuation of the urethral mucosa with the cutaneous epidermis of the prepuce, thus creating a closed preputial cavity surrounding the penis where fluid could accumulate. A persistent frenulum and a previously undescribed tissue remnant connecting the dorsal and distal aspects of the penis to the dorsal wall of the prepuce were also present. Surgical correction of the preputial and penile deformity, along with correction of the resulting paraphimosis and pendulous prepuce that became apparent following the initial surgery, are discussed.  相似文献

A 2-year-old intact male alpaca was presented for a post-breeding preputial prolapse of 5 days duration. The internal lamina of the prepuce was prolapsed approximately 6 cm and the exposed preputial epithelium was edematous and necrotic. Following 7 days of medical treatment, resolution of the preputial prolapse was achieved.  相似文献

Abstract: A 7‐year‐old neutered male polecat‐type ferret (Mustela putorius furo) was presented for evaluation of a cutaneous mass close to the preputial orifice. Cytologic examination of a fine‐needle aspirate revealed numerous large clumps of amorphous pink mucinous material and numerous large clumps of slightly pleomorphic epithelial cells. The cells were arranged in papillary structures, palisades, and loosely cohesive sheets with a vaguely honeycomb appearance. Occasional acinar formations were also seen. The cells had moderate to large amounts of finely granular gray to gray–blue cytoplasm. The cells were round to wispy and elongated, with indistinct borders. Often, anuclear cytoplasmic clumps were seen free in the background or adjacent to intact cells. Nuclei were round to oval and usually off‐center. Chromatin was finely stippled and contained 1–3 indistinct nucleoli. Anisokaryosis and anisocytosis were moderate. Binucleated cells were noted occasionally. The cytologic features were consistent with a carcinoma of probable apocrine origin. Histopathologic examination supported a diagnosis of secretory apocrine adenocarcinoma of the preputial skin. Secretory apocrine adenocarcinomas of the prepuce are seen relatively frequently in ferrets, although their cytologic appearance has not been described widely. These neoplasms carry a poor prognosis although prompt surgical removal with wide and deep surgical margins and adjunctive radiotherapy may improve survival.  相似文献

The case of a 2‐year‐old gelding with acute onset of preputial swelling and prolapse is presented. After initiating conservative management using a penile repulsion device, the horse repeatedly displayed signs of mild abdominal discomfort with sudden deterioration to an episode of violent colic after 5 days of hospitalisation. Ultrasonographic examination of the preputial swelling at that time demonstrated the presence of small intestine between the internal and external laminae of the prepuce and led to the diagnosis of a direct preputial hernia. The contents of the hernia were readily reduced through a defect in the ventral abdominal wall after the anaesthetised horse was placed in dorsal recumbency. The historical information, clinical progression and surgical findings were supportive of an acquired ventral abdominal wall defect. To the authors' knowledge, this is the first reported case of a direct preputial hernia associated with an acquired ventral abdominal wall defect.  相似文献

OBJECTIVE: To report a surgical technique for penile amputation and sheath ablation in horses. Study Design-Retrospective study. Animals or Sample Population-Twenty-five adult geldings of various breeds with conditions requiring penile amputation and sheath ablation. METHODS: The medical records of horses that had penile amputation and sheath ablation were reviewed. Briefly, the technique involved en bloc resection of the skin and subcutaneous tissues of the inner and outer lamina of the prepuce and penile shaft. Resection of the penile shaft, proximal to diseased segments, and spatulation of the urethral mucosa was followed by fixation of the penis to the ventral abdomen and closure of the peripreputial skin over the ventral aspect of the penis and creation of a new mucocutaneous junction at the urethral orifice. RESULTS: Mild to moderate postoperative hemorrhage occurred in all horses. Partial dehiscence of the mucocutaneous junction occurred in 8 horses; all healed by second intention. Postoperative pain lasting 24 to 48 hours occurred in 7 horses; 1 required epidural analgesia for pain relief. Long-term follow-up was available for 8 horses; none had any long-term complications. CLINICAL RELEVANCE: Partial amputation of the penis with pexy to the ventral abdomen and revision of the peripreputial skin can be used as an alternative to en bloc resection and penile retroversion for lesions involving the free part of the penis and the prepuce. It requires smaller incisions and results in less alteration to the normal appearance of the external genitalia than retroversion techniques, while still allowing the surgeon to remove extensive portions of the penis and extirpate the regional lymph nodes.  相似文献

Abstract

CASE HISTORY: A 2-year-old Hereford bull was lame for one week before becoming recumbent.

CLINICAL AND PATHOLOGICAL FINDINGS: The scrotum and ventral perineal region were cold and blackened caudally. The semimembranosus and semitendinosus muscles were firm on palpation. The bull was subject to euthanasia, and necropsy revealed that the skin and S/C tissues of the caudal half of the scrotum were grey and necrotic. The caudal and distal aspects of the semimembranosus and semitendinosus muscles were grey and necrotic to a depth of approximately 15 cm, and these changes appeared to track along fascial planes. The tissue had an offensive smell, and large amounts of flocculent, watery, brown fluid and some gas were present. Histology of affected muscle and S/C tissues revealed coagulative necrosis, with oedema and large numbers of bacteria that were predominantly Gram-positive rods. Adjacent blood vessels contained thrombi while the epidermis overlying the affected areas appeared diffusely necrotic, suggesting infarction. Culture of the fluid yielded a pure growth of Arcanobacterium spp., which was identified as Arcanobacterium haemolyticum, using an API Coryne biochemical test strip.

DIAGNOSIS: Necrotising fasciitis and myositis due to Arcanobacterium haemolyticum.

CLINICAL RELEVANCE: Arcanobacterium haemolyticum has not previously been reported as a cause of necrotising fasciitis in any species. Necrotising fasciitis is probably an under-reported condition in cattle due to its clinical similarity to clostridial disease.  相似文献
