[Evaluation split renal function and compensatory hypertrophy using a radio-isotopic technique]

Using a new method for the determination of split renal function with a radio-isotopic technique (FG Hipaque I131 and PRP Hippuran I131) we sought to determine residual renal function with pre-operative studies, especially in preparation for nephrectomy, and secondly with postoperative studies of compensatory renal hypertrophy after total or partial nephrectomy and the restoration of function in the kidneys following surgery of the urinary tract. A total of 20 cases was studied. We noted marked compensatory hypertrophy after total and partial nephrectomy and the prompt return of function after procedures involving the urinary tract, on condition that any acute infection be prevented.
