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 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

The aim of this study was to describe a modified surgical technique for treatment of severe penile pathology, and the long‐term outcome. The surgery consisted of subischial urethrostomy and penile amputation with preputial ablation, with the horse in dorsal recumbency. A redundant section of the penis root and body was left in situ, rather than being retroflexed as described elsewhere. Follow‐up was obtained using a structured owner telephone questionnaire. The 15 cases included: 11 squamous cell carcinomas (73.3%); 2 melanomas; one chronic preputial discharge with no associated neoplasia; and one paraphimosis following routine sedation. Length of survival ranged from 0.9 to 74.6 months (median 25.1 months). From the 14 horses with follow‐up, 9 survived >18 months (64.3%) [Correction added on 17 August 2015, after first online publication: The percentage in the preceding sentence was wrong and has been corrected to '64.3%' from '69.2%']. Four euthanasias were due to presenting or post operative complications, while 2 were unrelated to the procedure. This procedure presents a simplified, viable option for treatment of extensive mixed penile lesions; reducing surgical complexity and time in comparison to previously described techniques requiring retroversion. 相似文献

Circumcision (or reefing operation) was performed on an aged pony stallion to remove excessive granulation tissue involving the preputial integument following an injury and subsequent paraphimosis. Postoperative swelling of the penis and prepuce was reduced daily with gentle massage. Initially, an improvised suspensory was used to support the penis postoperatively. The pony was able to voluntarily retract its penis six months following surgery. 相似文献

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

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

Here we present a case of preputial benign fibrous histiocytoma in a 7‐year‐old mule. This case was treated surgically. Pathologic analysis and diagnosis of these lesions were based on a combination of light microscopy and immunohistochemistry. Histologically, the tumour was composed primarily of a storiform pattern of fibroblastic and poligonal cells. In immunohistochemistry, except for consistent immunoreactivity for vimentin, nearly all tumour cells were positive for CD68, S‐100 protein, pan‐cytokeratin, alpha‐smooth muscle actin, and desmin. Benign fibrous histiocytoma of the prepuce in mule is rarely reported in veterinary literature. 相似文献

An 11‐year‐old gelding presented with a large mass located in the dermis of his preputium that surrounded the penis completely. This mass was first noted years ago but did not increase in size. Histological examination diagnosed a fibroma. No treatment was initiated since no signs of discomfort were noticed and the gelding was performing at a high level in competitive showjumping. Next to skin tumours, tumours of the penis and preputium are most common. Most frequently, squamous cell carcinomas and sarcomas are diagnosed. Although fibromas can develop anywhere in connective tissue, a preputial location of a fibroma in a gelding is rare. Differential diagnosis and possible treatment options are discussed. 相似文献

A 21‐year‐old gelding with ventral abdominal and preputial oedema was evaluated for right hindlimb lameness. Partial phallectomy had been performed 3 years prior for treatment of squamous cell carcinoma. Regional analgesia did not localise the source of lameness and nuclear scintigraphy was recommended. The results of the scan revealed severe increased radiopharmaceutical uptake in the proximal femur. Radiographic and ultrasound examinations were inconclusive. The horse was discharged with recommendations of stall confinement and a 2 week course of nonsteroidal anti‐inflammatory drugs. Four weeks later the horse presented for an inability to elevate his neck and persistent hindlimb lameness. The owner elected humane euthanasia. Post mortem examination revealed metastatic squamous cell carcinoma in the proximal femur and fifth cervical vertebrae consistent with metastasis from the penile squamous cell carcinoma. To the authors’ knowledge, multiple site bone metastasis of squamous cell carcinoma has not been reported previously in the horse. 相似文献

The traditional diagnostic test for Tritrichomonas foetus involves collection of preputial or vaginal samples followed by culture in a growth media and microscopic examination. Recently, polymerase chain reaction (PCR) techniques have been described for use as a diagnostic assay. The objective of this study was to evaluate a previously described PCR assay for detecting T. foetus in cultured preputial material. The detection limits of the assay for T. foetus organisms in a growth medium, in samples prepared from washing microscope slides, and in preputial material cultured in a growth medium were determined. Preputial samples were collected from 13 bulls uninfected with T. foetus. The PCR assay was able to detect 5 T. foetus organisms in the growth medium and the cultured preputial material. Amplification products were obtained from samples prepared from washes of microscope slides containing as few as 3 visualized organisms. The PCR assay was able to detect organisms in culture at a lower concentration than was possible by direct microscopic examination. This low detection limit may allow the PCR assay to be used to enhance the sensitivity of the current diagnostic test. In addition, the assay could be used to confirm the identification of T. foetus organisms observed by direct microscopic examination when other confirmation techniques, such as staining and phase microscopy, are not practical. 相似文献

In this study, two unusual presentations of canine prostatitis are described; in the first case a 10‐years‐old neutered Boxer dog was presented to the Veterinary Teaching Hospital of the University of Extremadura with a complaint of anorexia, apathy and preputial discharge. In the second case, a local veterinarian referred an 8‐years‐old male Labrador to the Veterinary Teaching Hospital of the University of Extremadura. The dog had a history of pain in the caudal abdomen and preputial oedema. The final diagnosis in both cases was acute prostatitis. It is concluded that although canine prostatitis is a common disease, sometimes can have presentations that may differ from those classically described in the literature. 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

Prevalence of Histophilus ovis and Actinobacillus seminis in the genital tract of sheep 总被引：1，自引：0，他引：1
Histophilus ovis and Actinobacillus seminis were isolated from the preputial cavity of 6-month-old rams and the vagina of 6-month-old ewes at a substantially higher rate than that in mature (greater than 2 years old) rams and ewes. These organisms appeared to be a transitory component of the ovine genital flora, the prevalence of which was associated with age regardless of gender. Additional evaluation of the recoverability of H ovis and A seminis from the preputial cavity of rams from birth to 1 year of age indicated that the isolation rate from rams and predominance of the organisms in the preputial cavity differed greatly over this age period. These organisms were not recoverable until ram lambs were 12 weeks of age and were most prevalent at 20 weeks of age, after which recoverability of H ovis and A seminis from the preputial cavity steadily decreased, continuing through the time of the last evaluation at 1 year of age. The time period with which these organisms can be isolated from the preputial cavity is closely correlated with the time period when epididymitis associated with these organisms develops, and may be an important factor in the pathogenesis of epididymitis. 相似文献

A one‐year‐old male domestic short haired cat was referred because of an area of keratitis that had developed adjacent to a particularly large unilateral eyelid coloboma. The defect was repaired using an undescribed three‐stage surgical technique, which is essentially a combination of existing techniques and consists of using the lower lid to re‐construct the upper lid and replacing the resultant lower lid defect with a full thickness graft from the upper lip. This technique is described and the results illustrated by photographs. A good functional and cosmetic result was achieved. 相似文献

Objective— To report a surgical technique for creation of a urethral conduit using a preputial indirect flap.
Study Design— Case report.
Animals— Male Doberman Pinscher (6 weeks old).
Methods— A urethral conduit was constructed using a multistage preputial indirect flap in a dog with severe perineal hypospadias.
Results— Successful transfer of a perineal located urethral meatus to a more anatomically normal inguinal location was achieved with a preputial flap. The procedure was performed to aid control of recurrent urinary tract infections after anal and urethral separation in a dog with imperforate anus, urethrorectal fistula, and proximal perineal hypospadias.
Conclusions— Creation of a urethral conduit from a tubed bipedicle flap using redundant preputial tissue eliminated fecal contamination of the urethral meatus, aiding control of urinary tract infection. A good functional and cosmetic outcome was achieved.
Clinical Relevance— This technique should be considered in aiding control and prevention of urinary tract infections in dogs with proximal perineal hypospadias where a preputial remnant exists. 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 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

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
