A 7‐year‐old intact male Boxer was referred to our services at the Veterinary Teaching Hospital of the University of Trás‐os‐Montes and Alto Douro, suffering from a persistently erect penis (including the bulbus glandis) that had been exposed for several days. Radiographic and ultrasonographic examinations detected a 5.0 × 3.5 cm mass located dorso‐laterally to the urinary bladder. The microbial culture of the mass revealed Staphylococcus spp. At that time, we suspected the involvement of an abscess in the origin of the priapism. Medical and surgical treatments were promptly instituted, which allowed for penile withdrawal into the prepuce; however, the resolution of the penile erection was not accomplished in the following days and penile amputation was required. Histological evaluation of the excised penis revealed extensive infarction of the erectile tissue of the pars longa and bulbus glandis, and also of the blood vessels of the penis. Following penile amputation and antimicrobial therapy, the animal fully recovered. Ultimately, the animal died as a consequence of gastric torsion. At necropsy, some lesions compatible with a previous perforation of the intestinal wall were recorded. The data gathered from the anamnesis, the physical and imaging examinations, along with the post‐mortem findings, allowed us to conclude that in this clinical case the primary cause of priapism was a perineal abscess due to bowel perforation. 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

Priapism developed in a cat 2 days after castration and strangury. The priapism was unresponsive to massage and antimicrobial treatment. Because of penile engorgement and necrosis, a perineal urethrostomy was performed. Clinical signs of priapism resolved after urethrostomy. Histologic examination of tissues revealed vascular stasis within the corpus cavernosum penis and funiculitis of the right spermatic cord. 相似文献

A 2-year-old dog was examined after a 22-month history of intermittent drying and chafing of the distal portion of the penis after traumatic loss of the cranial portion of the prepuce and fracture of the os penis at 8 weeks of age. A multiple-staged surgical procedure was performed to reconstruct the prepuce, including free buccal mucosal grafting and transfer of a peripreputial bipedicle subdermal plexus flap. Preputial reconstruction provided mucosal and cutaneous coverage of the penis. 相似文献

Partial phallectomy or en bloc resection are surgical methods to address pathological conditions of the penis and/or prepuce including neoplasia, trauma, habronemiasis, chronic paraphimosis or permanent penile paralysis, and priapism. Haemorrhage associated with urination is a common complication observed after penile surgery but usually resolves spontaneously without specific treatment. This report describes a case of post urination haemorrhage (PUH) that recurred with each urination and persisted without significant improvement for a period of 2 weeks following en bloc resection of the penis and the prepuce. A perineal incision (PI) into the corpus spongiosum of the penis (CSP) resolved PUH by decreasing the blood pressure in the CSP distal to the PI. We propose that PI of the CSP can be an effective method to address PUH after penile surgery and may decrease time of hospitalisation for horses affected with PUH after phallectomy procedures. 相似文献

A case of preputial glomangioma in an 8-year-old Springer Spaniel dog is reported. The dog presented a solitary nodular mass, approximately 3.5 x 5.2 cm in diameter, located on the lateral wall of the prepuce at the base of the penis. Histologically, the excised tumour mass consisted of proliferating round epithelioid cells arranged in a cordon-like structure around small blood vessels. The neoplastic cells were positive for alpha smooth muscle actin and negative for cytokeratin, desmin, S-100 protein and neurone-specific enolase. Based on these pathologic features, the tumour was diagnosed as glomangioma, a neoplasm extremely rare in dogs. To our knowledge, this is the first report of preputial glomangioma in the dog. 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

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

Objectives : The overall aim of this study was to examine the nature of the relationship between dog‐ownership and canine obesity, explored in two cohorts of overweight/obese or non‐overweight dogs (n=125). This paper concentrates on the owners’ perception of dog weight. Methods : A researcher‐mediated questionnaire was used to collect data from dog owners attending a small veterinary practice. Interviewees (n=121) were asked qualitative and quantitative questions, designed to examine the owners’ views of their relationship with their dogs. Results : Although a high proportion of owners claimed to have discussed the dog's weight with their veterinarian, some discrepancies were apparent between owner perception of animal weight and the veterinarian's evaluation of body condition score. Owner disagreement was significantly greater for the veterinarian‐defined overweight dogs (P=0·005). Owners often provide personal narratives to account for their dog's weight status. Clinical Significance : This study confirms the important role of the vet in providing information about the issue of dog weight but also suggests that providing verbal information is sometimes insufficient. The study also indicates the potential value of qualitative research methods to further understand client perception of complex animal care issues and highlights the need for further in‐depth research. 相似文献

A 7‐year‐old neutered male Jack Russell terrier‐cross was presented for signs of recurrent paraphimosis, despite previous surgical enlargement of the preputial ostium. Revision surgery was performed using a combination of preputial advancement and phallopexy, which resulted in complete and permanent coverage of the glans penis by the prepuce, and at 1 year postoperatively, no recurrence of paraphimosis had been observed. The combined techniques allow preservation of the normal penile anatomy, are relatively simple to perform and provide a cosmetic result. We recommend this combination for the treatment of paraphimosis in the dog, particularly when other techniques have failed. 相似文献

A Thoroughbred stallion developed priapism that was unresponsive to medical treatment and lavage of the corpus cavernosum penis with heparinized 0.9% NaCl solution. Three weeks after onset of priapism, the penis was firm and noncompliant, and penile pain sensation and ability to retract the penis were lost. Ultrasonography confirmed thrombosis of the corpus cavernosum penis. The stallion was euthanatized because of poor prognosis for return to breeding soundness. Necropsy revealed enlargement of numerous lymph nodes. The dorsal penile nerves were demyelinated distal to the crura of the penis. A diagnosis of generalized malignant melanoma was made; however, neither metastasis to the vertebral canal nor compression of spinal nerve roots as they exited the vertebral foramen was found. Priapism is a persistent erection without sexual arousal and is initially unassociated with penile paralysis, but if prolonged, leads to irreversible venous occlusion where collecting veins join the cavernous spaces. Damage to the dorsal penile nerves may explain the long-term penile paralysis and loss of sensation that accompanied priapism in this stallion. Priapism unassociated with the use of phenothiazine-derivative tranquilizers is uncommon in horses. 相似文献

Three dogs with recurrent paraphimosis were surgically treated by creation of a phallopexy between the dorsal surface of the penis and the corresponding surface of the prepuce. Follow-up evaluation was performed 4 to 31 months postoperatively. Treatment was successful in each case, and no dog had any adverse sequelae. 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 8-year-old Quarter Horse stallion was admitted with a swelling involving the prepuce, dorsal part of the scrotum, and root of the penis. The swelling was first noticed 10 days after breeding, with no evidence that it had resulted from a kick by the mare. The penis was retracted into the prepuce, except for a 10- to 15-cm protrusion of the glans penis. Treatment included warm hydrotherapy, massage, stockinette compression, antidiuretics, antibiotics, penile support, and exercise, without success. At necropsy, a massive preputial hematoma was found extending forward from the root of the penis to 12 cm proximal to the glans penis. The exact origin of the hematoma could not be determined. Most likely, bleeding had originated from the vascular plexus lying subfascially on the surface of the penis outside the intact tunica albuginea or from a branch of the external pudendal artery. 相似文献

Electrophysiological Studies of the Cutaneous Innervation of the External Genitalia of the Male Dog 总被引：1，自引：0，他引：1
The external genitalia and perineum of the male dog receive cutaneous innervation from the caudal cutaneous femoral, superficial perineal and genitofemoral nerves and the dorsal nerve of the penis. In addition the cranial and caudal iliohypogastric nerves occasionally supply the prepuce. Considerable overlaop between adjacent cutaneous areas, particularly on the prepuce, is noted and the extent of all cutaneous areas is greater and more expansive than previosly described. Only the cutaneous area of the genitofemoral nerve is reduced from earlier accounts, being restricted to the prepuce, inguinal region, and medial thigh but never supplying the scrotum. 相似文献

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

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

A review of the literature is given concerning the anatomy and pathophysiology of the equine penis with regard to priapism: a prolonged erection of the penis not associated with sexual arousal. Several treatment options, such as flushing of the corpus cavernosum penis with heparinized saline and the creation of shunt between the corpus cavernosum penis and the corpus spongiosum penis are discussed. Subsequently, a case of priapism in a stallion following the injection of acepromazine, is discussed. The priapism resolved after the corpus cavernosum penis was flushed with the stallion under general anaesthesia. 相似文献

Various types of hypospadias and methods of surgical treatment of this anomaly in 6 dogs was described in this article. Methods of surgical treatment were set up individually for each case and depended on the type of hypospadias and coexisting anomalies. Shortening of the penis was performed in two dogs, amputation in three cases and an urethral reconstruction in one patient. Castration was performed in three cases. Persistent frenulum of the prepuce was found in two dogs. Additionally three patients were submitted to the plastic surgery of the prepuce anomalies. In one dog, the loose and free falling part of the prepuce was suspended and attached to the abdominal integument according to the original own method. In all dogs, uncomplicated wound healing was observed. Surgical procedures resulted in improved cosmesis with reducing clinical signs of hypospadias and other coexistent anomalies. 相似文献

A 1‐year‐old Shih Tzu dog was presented for examination because of abnormal external genitalia. A residual penis with a prepuce was located in a position typical of a male. The dog had no palpable testicles or scrotum. The ultrasound examination revealed the presence of the prostate, but the gonads remained undetectable. Cytogenetic analysis performed on chromosome preparations obtained from lymphocyte culture showed two cell lines – 78,XX and 78,XY. Molecular analysis of 14 polymorphic microsatellite markers allowed us to distinguish leucocyte chimerism from whole body chimerism. The presence of 3 or 4 alleles was confirmed in DNA isolated from blood, while in DNA isolated from hair follicles only 1 or 2 alleles were detected. The case was classified as leucocyte 78,XX/78,XY chimerism. Our study showed that XX/XY leucocyte chimerism might be associated with disorder of sexual development in dogs. Furthermore, it is emphasized that the use of cytogenetic study, in combination with analysis of polymorphic markers in DNA isolated from different somatic cells, facilitates distinguishing between leucocyte and whole body chimerism. 相似文献
