[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.
