Systemic hypocalcemia after clinical injections of radiographic contrast media: amelioration by omission of calcium chelating agents.

abstract：:In men who otherwise seem to have responded to chemotherapy for nonseminomatous germ cell tumors (NSGCTs), enlarging masses can represent benign tissue rather than residual or recurrent malignancy. One hundred eighty-five men with negative serum tumor markers after first-line chemotherapy for NSGCT underwent surgical ...
