Estimation of Renal Function.—A very difficult featurein the diagnosis of renal lithiasis is the clinical estimate ofthe degree of functional capacity remaining in the affectedkidney. The amount of pus in the urine catheterized fromthe affected kidney does not always indicate the degree of RENAL STONE 215 functional destruction, nor does temporary cessation ofsecretion, as observed through cystoscopic inspection, in-dicate diminution in the amount of secretory of renal functional capacity by means of chemicaltests has frequently been found inaccurate in case of renallithiasis.
