Ureteral substitution using the isolated interposed vermiform appendix in a patient with a single kidney and transitional cell carcinoma of the ureter.
A patient with a single kidney presented with ureteral obstruction caused by a combination of primary transitional cell carcinoma of the ureter and extrinsic involvement of the ureter by a second primary malignant retroperitoneal lymphadenopathy. Due to the complexity of the case, we chose to perform a partial ureterectomy and used a method of ureteral substitution using the interposed vermiform appendix in combination with a psoas hitch. Application of the psoas hitch may allow the use of the appendix in most cases in which ureteral substitution becomes necessary. Antireflux mechanism is easily achieved with the appendix using the split cuff nipple technique. Finally, the use of the appendix allows complete retroperitonealization of the anastomoses to both ureter and bladder. We anticipate that the appendix will be used more commonly in the future as a ureteral substitute as more urologists become more comfortable with it through its use in various reconstructive procedures.
