However, increasing trend towards elective nephron sparing surgery (ENS), only a few studies can be found imperative nephron sparing surgery (INS). In this study we compared patients after they had undergone NSS with regard to renal function and oncological long-term follow up.
We defined two groups, A group consisted of RCC occurred after radical nephrectomy in 5 cases and RCC occurred in patient with congenital single kidney in one case, on the other hand B group consisted of two patients who had bilateral renal tumors simultaneously.
The mean follow-up was 89months (range 24-228 months), all of 7 patients survived without recurrence.
A group; previous pathological revealed that 5 cases were clear cell carcinoma (CCC), pathological grade 1-2, pT1a-2, average recurrence duration were 113months, Preoperative evaluation, nephrometry score were 4-10 point (average 6 point) all cases were CCC. 4 cases were pT1a, remaining case was pT3a, Clampless had underwent 3cases, 2 cases had used microtase coagulator, remaining one case underwent soft coagulator with suture less procedure. The mean preoperative GFR was 56ml/min, and mean postoperative GFR was 53ml/min. Two of them showed postoperative recurrence, mean time was 96 months. The mean preoperative GFR was 55ml/min, and mean postoperative GFR was 46min/ml.
B group; All of two patients underwent partial nephrectomy for one side tumor which had a larger size than another one. Several months later patients underwent surgical procedure with contra lateral tumor. All tumor resection underwent with mechanical renal pedicle clamping.
The mean preoperative GFR was 50.5ml/min. and postoperative GFR was 33.4ml/min. then one of them had underwent hemodialysis 4 years later.
However oncologic surgical outcome seems to be appropriate for INS, regarding postoperative renal function, indication of INS for bilateral tumors should be consideration.
