[Risk of tumor seeding after nephroureterectomy combined with endoscopic resection of the ureteral meatus].
OBJECTIVE
To describe a case of tumor implantation at the site of resection in the ureteral orifice, following nephroureterectomy combined with resection of the bladder cuff of.


RESULTS
A patient with high grade and stage carcinoma of the renal pelvis and no previous bladder tumor presented with a perivesical mass 6 months following nephroureterectomy. She had a high grade transitional cell carcinoma that infiltrated all of the bladder wall, vagina and parametrium in the region of the meatus that had been resected endoscopically.


CONCLUSIONS
The present case indicates there may be histological or technique-related factors that facilitate tumor cell implantation in the deep perivesical region after this procedure is performed. It is necessary to identify these factors before this procedure is used widely.
