  • Title: [Risk of tumor seeding after nephroureterectomy combined with endoscopic resection of the ureteral meatus].
    Author: Fernández Gómez JM, Barmadah SE, Pérez García J, Rábade Rey CJ, Rodríguez Martínez JJ.
    Journal: Arch Esp Urol; 1998 Oct; 51(8):829-31. PubMed ID: 9859592.
    Abstract:
    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. METHODS/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.
