Surgical Conditions

  • Cryptorchidism is the failure of one or both testicles to descend into the scrotum. Toy breeds may be more at risk, but it can affect any breed of dog and is believed to be an inherited trait. Diagnosis can usually be made by palpation but sometimes requires blood testing or an abdominal ultrasound if the dog’s history is unknown. Risks of retained testicles include testicular cancer, spermatic cord torsion, and the development of undesirable male characteristics, so neutering is strongly recommended. Surgery is generally routine, and recovery is similar to any abdominal surgery.

  • Round cell tumors are among the most common skin tumors in dogs, and they typically form just under the skin, although they may change the surface of the skin above them. It is impossible to diagnose any of them without a veterinary pathologist analyzing a tissue sample of the tumor under a microscope. If detected early, most round cell tumors can be easily removed.

  • There are many health and behavioral benefits associated with spaying your rabbit, such as preventing unwanted pregnancies, reducing her risk for reproductive cancers, and minimizing the stress associated with sexual frustration. This handout explains the surgical procedure, post-operative care at home, and, although rare, possible complications that may occur.

  • An ovariohysterectomy is often referred to as a spay or spaying. It is a surgical procedure in which the left and right ovary and both left and right horns of the uterus are removed completely, to sterilize or render a female animal infertile. Spaying minimizes the risk of ovarian, uterine, breast, and pituitary gland cancers in rats. Ideally, most rats are spayed between four and six months of age. Complications are rare, but there is a small risk associated with being anesthetized. Most rats will experience no adverse effects and spaying is generally recommended for all healthy, young rats to prevent future health problems.

  • Squamous cell carcinoma (SCC) is a tumor of the cells that make up the contact or upper layer of the skin. UV light exposure has been described as a developmental factor in people and appears to be associated with its development in cats. Areas affected include the ear tips, skin, toes, or peri-ocular region. Fine needle aspiration or biopsy may be performed for diagnosis. The metastatic rate does not appear overly clear, though staging is always recommended. SCC of the toe can occur as a primary tumor or may have spread from the lung (lung-digit syndrome). Surgery is almost always recommended in any case of SCC; the role of chemotherapy is controversial. Radiation therapy has an excellent response rate in cats with the SCC affecting the nasal planum and may give long-term tumor control.

  • Squamous cell carcinoma is a tumor of the cells that make up the contact or upper layer of the skin. UV light exposure has been described as a developmental factor in people, though it is still in question as to the role for dogs. Several breeds are known to be predisposed to this type of cancer. About 30% of dogs with the digital form of the disease will have evidence of spread. Regardless of the location, surgery is typically the treatment of choice, and staging is usually recommended prior to any surgery.

  • Struvite bladder stones are one of the most common bladder stones in cats. In some cats, struvite bladder stones form because of a urinary tract infection. Signs of bladder stones typically include frequent urination, straining to urinate, blood in the urine, and urinating outside of the litterbox. If your cat is having urinary issues, your veterinarian will first recommend a urinalysis. Blood tests, abdominal X-rays, and ultrasound may also be recommended. Medical dissolution and surgical removal are two categories of treatment. Cats who have developed struvite bladder stones are likely to experience a recurrence later in life, unless the conditions that led to the formation of stones can be corrected.

  • Struvite bladder stones are one of the more common bladder stones found in dogs. Struvite bladder stones usually form as a complication of a bladder infection caused by bacteria, and if the urine becomes exceptionally concentrated and acidic. The most common signs that a dog has bladder stones are blood in the urine (hematuria) and straining to urinate (dysuria). There are three primary treatment strategies for struvite bladder stones: 1) feeding a special diet to dissolve the stone(s), 2) non-surgical removal by urohydropropulsion (flushing out the stones) and 3) surgical removal. Dogs that have experienced struvite bladder stones will often be fed a therapeutic diet for life.

  • Home care after surgery mainly involves the restriction of physical activity. Excessive physical activity often leads to injury or serious complications. Monitor the incision daily for signs of redness, swelling, discharge, or excessive licking, and never apply anything to the incision unless instructed to do so. To keep your cat from licking, your veterinarian can provide you with a protective collar or recovery suit. Your cat should gradually improve each day.
