Background:
In this paper, we reported nephron sparing surgery for renal mass in our hospital.
Methods:
From March, 1994 to October, 1997, nephron sparing surgeries were done for 19 (11 males and 8 females, whose age were ranged from 38 to 75 years old) renal mass in our hospital. The sites of lesion were 12 in right side and 7 in left side. The tumor size were from 8 to 40/mm. Almost all cases were discovered incidentally.
Results:
In all 19 cases, 6 cases were resultingly renal cell carcinoma (RCC). There was no difference in age, sex, tumor size and computed tomography findings between RCC and benign lesion. In magnetic resonance imaging (MRI) findings, iso intensity lesions of T2-weighted image were more frequent in RCC significantly. Postoperative 24 hours creatinine clearance and serum creatinine were not changed significantly compared with preoperative data.
Conclusion:
In MRI findings, iso intensity of T2-weighted image was useful for differential diagnosis between RCC and benign lesion.
