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

A modified perineal urethrostomy was performed in 14 males cats with partial or complete urethral obstruction. Follow-up information was available for 2 to 18 months. By use of this method, the preputial tissues were preserved, and the penile urethra was anastomosed to the preputial mucosa to enlarge and lengthen the urethra. Urine flow was reestablished in all cats without evidence of urethral stenosis or other major complications. Appearance of the perineal region and prepuce was not substantially altered. 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 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

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

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 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

Fifteen cats were evaluated with urethral obstruction. Penile trauma by catheterization was the major indication for perineal urethrostomy. Ten cats had developed a urethral stricture and five had rupture of the urethra following medical management. All cats had abnormalities in penis and/or prepuce and/or scrotal sacs including hyperemia or swelling. Perineal urethrostomy was performed in all cases and they were evaluated for 6 months after surgery. Few complications were noted. Urinary tract infection was the most frequent complication observed. The clients considered their cats to have a good quality of life following surgery. 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 4-yr-old, 300-kg male Bongo antelope presented a fluctuant swelling on the ventral abdomen surrounding the penis, which was confirmed later as compatible with urethral rupture. Initial treatment included broad-spectrum antibiotic and radical surgical debridement. Total prepuce and partial penile amputation with orchidectomy was performed and normal micturition was restored. At a later stage, when the extent of the lesion was controlled, a permanent scrotal urethrostomy was performed. Complete healing by second intention was achieved 2 mo after the last surgery. Although the outcome was very good, considering the extent and severity of the tissue damage, prompt permanent urethrostomy when urethral rupture was first suspected would have prevented deterioration of the condition and prevented the need for extensive surgery. 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

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

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

A cat with pelvic fractures from being hit by a car had voided no urine in 13 hours despite iv administration of fluids. Abdominal radiography had revealed the pelvic fractures and apparently intact urinary bladder. Urine did not flow from a urethral catheter, and contrast radiography revealed the catheter to be extra-urethral within the penis. Intravenous pyelography revealed intact ureters and urinary bladder; celiotomy confirmed intact urinary bladder. Cystotomy and normograde urethral catheterization allowed localization of the ruptured urethra within the deep subcutaneous tissues of the caudal portion of the abdomen. After closure of the cystotomy and celiotomy incisions, perineal urethrostomy was performed. 相似文献

Antiseptic flushing of the canine prepuce and its exclusion from the surgical field are recommended before abdominal surgery to reduce the risk of bacterial contamination. The authors cultured the preputial cavity of 60 dogs prior to and following flushing with 0.05% chlorhexidine diacetate, 1% povidone-iodine, or 0.9% saline control. Bacterial growth was evaluated using a semiquantitative method, and bacterial organisms were subsequently identified. There were no significant differences between povidone-iodine and the saline control in any of the variables assessed. Chlorhexidine resulted in a significant decrease in the proportion of positive postflush cultures compared with povidone-iodine. Although not significant, the difference in adverse reactions between povidone-iodine (25%) and chlorhexidine diacetate (5%) suggests clinical relevance. Based on the results of this study, a 2 min flush with 0.05% chlorhexidine diacetate is recommended for presurgical preparation of the preputial cavity. 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

The medical records of 10 horses with invasive neoplasms of the penis, prepuce, and/or superficial inguinal lymph nodes in which treatment involved en bloc resection and penile retroversion were reviewed. All were geldings and ranged in age from 12 to 25 years (mean, 19 years). Evaluation of biopsy specimens obtained before surgery confirmed lymphosarcoma in 1 horse and squamous cell carcinoma in 9 horses. Typical history included swelling, ulceration, and abscessation of the penis and prepuce and large superficial inguinal lymph nodes. Complications after surgery included dehiscence of the urethrostomy site (4 horses), dehiscence of the ventral skin incision (1 horse), urine scalding of 1 hind limb (1 horse), cystitis (1 horse), severe hemorrhage (1 horse), and diarrhea (1 horse). One horse was euthanatized during hospitalization, because of severe dehydration secondary to diarrhea. At necropsy, firm nodules were scattered in the pulmonary parenchyma, myocardium, thyroid gland, parathyroid glands, cranial mediastinum, kidneys, and hilar lymph nodes. Microscopic examination of the nodules revealed undifferentiated carcinoma. Nine horses were discharged from the hospital between 1 and 5 weeks after surgery. The mean follow-up interval was 27 months (range, 6 to 96 months). Eight horses had no evidence of recurrence. One horse had recurrence of neoplasm at 6 months and was euthanatized 12 months later. 相似文献

BACKGROUND: Malassezia-type yeasts previously have been observed on cytologic examination of the intermammary region of mares that presented with tail-head pruritus; topical antiyeast treatment resolved the pruritus. Further, Malassezia dermatitis has been observed in horses in intertriginous areas such as the udder and prepuce; the species of yeast was not confirmed. It is not known whether healthy mares or male horses can be carriers of this yeast in these body areas. HYPOTHESIS: Malassezia spp. are present in the intermammary region in healthy mares and the preputial fossa in healthy geldings. ANIMALS: Eleven healthy horses (5 mares and 6 geldings). METHODS: Samples of surface material were taken digitally from the intermammary area of 5 mares and the preputial fossa region of 6 geldings. The samples were examined cytologically and were cultured on modified Sabouraud's dextrose agar. The DNA from yeast colonies grown on the agar was extracted, and samples were assayed using fungal generic polymerase chain reaction (PCR) analysis. Amplicons with positive PCR results were sequenced and compared with sequences in the BLAST database search program. RESULTS: Of 44 attempts at culture, 5 yielded a species identified as Malassezia equi, and 2 yielded M slooffiae. In contrast, of 44 cytologic examinations, yeasts with the morphology of Malassezia spp. were seen in 40 samples. CONCLUSIONS AND CLINICAL IMPORTANCE: Due to its presence in healthy horses, finding of Malassezia-type yeast on cytologic examination may not incriminate it as a pathogen. Despite difficulty in culturing, cytologic examination was an effective tool to rapidly demonstrate the organism. 相似文献
