Nonneurogenic urinary incontinence in a canine female pseudohermaphrodite.
Nonneurogenic incontinence was observed in a 1-year-old Pekingese X Poodle with female pseudohermaphroditism. The dog had male external genitalia as well as a well-developed vagina, uterus, and ovaries. Urinary incontinence was caused by an anomalous communication of the prostatic urethra with the vagina. Ovariohysterectomy and surgical correction of the urethrovaginal fistula was followed by remission of urinary incontinence. Subsequently, the dog developed estrogen responsive urinary incontinence. Nonneurogenic incontinence to be a common finding in canine pseudohermaphroditism associated with abnormalities of the vagina or urethra (or both). Surgical correction should be considered to correct anomalous communications between the genital and lower urinary tracts.
Midline myelotomy of the clinically normal canine spinal cord.
Clinically normal dogs underwent dorsal laminectomy, durotomy, and full-thickness midline myelotomy between either the 1st and 2nd lumbar vertebrae or the 3rd and 4th lumbar vertebrae. The myelotomy was 1 1/2 vertebral bodies long and was performed with a microbalance spatula. Neurologic and histopathologic changes were recorded. Full-thickness midline myelotomy done by this technique was found to cause severe necrosis of spinal gray matter.

Modified deep dorsal laminectomy in the dog.
Spinal cord compression subsequent to radical laminectomy was investigated. A modified deep dorsal laminectomy technique was devised to allow extensive exposure and decompression of the canine spinal cord without undue hazard of postoperative fibrotic spinal cord compression. A previously described laminectomy technique was modified by the addition of spinal plating to avoid the occurrence of constrictive fibrosis.
