Use of ultrasonographic and nuclear imaging to diagnose scrotal hernia in a dog.

Ultrasonography and nuclear imaging were used in the diagnosis of scrotal hernia in a dog. Both techniques were useful as aids in the differential diagnosis of scrotal enlargement. Nuclear imaging was useful in ruling out testicular torsion; ultrasonography revealed a normal-appearing testis amid fluid and portions of omentum.

Urinary tract trauma.

Trauma to the canine urinary tract is a common occurrence secondary to motor vehicle accidents. Radiology is an important diagnostic technique for determining the extent of traumatic injuries. The anatomic location of the urinary system in close association with the ribs, pelvis, epaxial muscles and spine may be an advantage because of the protection offered by these structures and a disadvantage because of increased injury when these structures are damaged. Trauma to the kidneys may be managed by complete nephrectomy, partial nephrectomy, renal capsule repair and temporary nephrostomy. Trauma to the ureters may be managed by ureteral anastomosis, ureteral splinting, ureterovesicular anastomosis, nephrotomy and ureteronephrectomy. Bladder trauma is managed with cystotomy, indwelling catheter, antepubic drainage and intestinal pouch attachment. Techniques for repair of the urethra include indwelling catheterization, urethral anastomosis, and urethrostomy at a new site. The post-operative complications most frequently encountered include uremia, wound dehiscence, stricture and infection. These complications can be avoided by restoration of anatomic continuity of the injured organ, internal splinting and catheterization, urinary diversion, and peri-operative drainage.

Soft tissue surgery of the head and neck.

A variety of surgical techniques and procedures have been described for diseases of soft tissues of the oral cavity. Mandibulectomy and maxillectomy have been described for the management of oral neoplasia. These procedures involve removal of parts of the mandible and maxilla in the affected regions of the mouth. Salivary mucocele or sialocele is defined as an abnormal accumulation of saliva in the tissues of the head and neck. Depending on the location of the salivary collection, swelling can occur in the ventral neck, under the tongue, or in the oropharynx just posterior to the tonsil. In the dog this condition is managed most successfully by excision of the mandibular and sublingual salivary glands on the affected side. The ventral approach is preferred because of ease of drainage postoperatively. Diseases of the soft palate which lend themselves to surgical correction include elongation of the soft palate and hypoplasia of the soft palate. Corrective surgery for both of these conditions is desirable and the surgical results are excellent. Tonsillectomy and removal of the tonsillar crypts is recommended along with excision of the elongated soft palate to enlarge the size of the airway.
