This is assessed by an ultrasound examination and measurement of serum creatinines after the transplant. Significant blockage of the ureter, as indicated by dilation of the ureter, would require a second surgery for revision of the opening of the ureter into the bladder. The ureter may also leak at its point of attachment. This is one of the most problematic areas in the surgery. Urine leakage would require additional surgery for revision of the ureter implant.
Rejection can occur at any time after surgery and is a threat for the remainder of the cats life.
The risk of rejection is greatest in the first month after surgery. Anemia is managed by erythropoeitin injections 2-3 times a week. This is continued until the kidney assumes its role in production of this hormone. The time for needing erythropoeitin may vary from days to months. In general, if the PCV is 25 or better we will forego erythropoeitin treatments.
