title: A mucosal apposition technique for ureteroneocystostomy after renal transplantation in cats.
abstract: Renal transplantation is a successful treatment for terminal renal failure in cats. However, in the initial clinical study, there was a frequent occurrence of obstruction of the implanted ureter at the bladder wall or stoma. This resulted in the use of a modified "drop-in" technique that had proved effective in the prevention of obstruction in five normal cats. When applied to renal transplant recipients, ureteral obstruction was reduced, but continued to occur. The modified "drop-in" technique was abandoned and replaced with a technique that apposed the cut edge of the ureteral mucosa to the torn edge of the bladder mucosa. This technique is recommended as it has prevented ureteral obstruction in six successive cases. Prevention of ureteral obstruction, and the required corrective surgery, markedly reduces patient morbidity and mortality, length of hospitalization, and expense to the client.
