Fluorescence of testicle. An indication of viability of spermatic cord after torsion.

We present an objective measure of testicular viability intended to aid the surgeon in salvaging the testicle at the time of operation for torsion of the spermatic cord. Following the intravenous administration of 5 to 10 cc. of sodium fluorescein, the viability of the untwisted testicle can be determined by its fluorescence when exposed to a portable long wavelength Wood ultraviolet light source.
