[Necessity of prophylactic contralateral nephroureterectomy in the renal transplantation patients with transitional cell carcinoma of unilateral upper urinary tract].

OBJECTIVE
To discuss the necessity of prophylactic contralateral nephroureterectomy in renal transplantation patients with upper urinary tract transitional cell carcinoma (TCC).


METHODS
In our study 15 renal transplantation patients with upper urinary tract TCC were involved from Dec.2006 to May 2013. All the patients received prophylactic contralateral nephroureterectomy 3 months after their last nephroureterectomy. A retrospective analysis was performed.


RESULTS
TCC of upper urinary tract was confirmed by postoperative pathology in all the 15 cases .Similarly, TCC of contralateral upper urinary tract was detected in 7 of these cases (46.7%), and 13 survived after 36 months' follow-up (86.7%).


CONCLUSION
In the renal transplantation patient with unilateral upper urinary tract TCC, the possibility of contralateral upper urinary tract TCC is high, thus the necessity of prophylactic contratateral nephroureterectomy is certain.
