In the propensity-score matched cohort of patients with clinical T1a RCC, we observed that RFA was an effective treatment option that provided comparable 5-year oncologic outcomes and better preservation of renal function than PN.

In appropriately selected patients with stage cT1b renal cell carcinoma radio frequency ablation is an effective treatment option that provides 5-year overall, cancer specific and disease-free survival comparable to that of partial nephrectomy as well as better renal function preservation than partial nephrectomy.

Gender disparity among living kidney donors is common world wide, which demonstrates different social and economic problems in different countries. However, few data are available for China. Therefore, we retrospectively analyzed all 139 living donor renal transplants performed in our center between 2003 and 2010. The annual number of living donor renal transplants increased from six to 26 cases per year during the observation period. Among them, 69.2% of all kidney donors were females, whereas 79.5% of the recipients were male. The average age of recipients was 34.1 ± 7.6 yr and 94% (110/117) were younger than 44 yr. In contrast, 53% (62/117) of all donors were "middle-aged" (45-59 yr) with an average donor age of 47.8 ± 9.2 yr. The first-degree relatives accounted for the majority of the donor pool, as the most common donor-recipient combination consisted of mother to son. In conclusion, there was a male and young preponderance among recipients, and a female and middle-aged one among donors of living kidney transplants in our transplant center, which might be related to socio-cultural as well as economic factors.

High preoperative neutrophil-to-lymphocyte ratio and elevated postoperative neutrophil-to-lymphocyte ratio are associated with significant increase in risk of local recurrence as well as distant metastasis. The combination of neutrophil-to-lymphocyte ratio with the other prognostic indicators can be applied in the evaluation of relapse risk in patients with clear cell renal cell carcinoma after radiofrequency ablation.
