Partial nephrectomy for renal tumour: 21 cases.

Partial nephrectomy has been performed in 21 cases of kidney tumours. It can be used for well-limited parenchymatous tumours and obligatory in patients with a solitary kidney, but is not advisable for tumours originating in the urothelium. These results are compared with the parallel experience with radical surgery and followed during 46 years in the same centre, they give a greater value to this study and encourage the reasoned practice of partial nephrectomy for tumours especially in the solitary kidney.
