  • Title: Utility of Rigiscan and papaverine in diagnosis of erectile impotence.
    Author: Weinberg JJ, Badlani GH.
    Journal: Urology; 1988 Jun; 31(6):526-9. PubMed ID: 2453968.
    Abstract:
    The Rigiscan machine was used to measure nocturnal penile tumescence and rigidity in 41 men referred for evaluation of erectile impotence. In 6 patients, the Rigiscan was compared with the Tumistore and Snap-Gauge bands. Two patients achieved significant tumescence as measured by Tumistore, and 3 had significant tumescence as indicated by the breaking of two or three of the Snap-Gauge bands. None of these men achieved sufficient rigidity for intercourse as measured by the Rigiscan. Fourteen patients with organic impotence received intracorporeal injections of papaverine and were then monitored by Rigiscan. Six of the 14 were noted to have a Peyronie plaque. Of the remaining 8, 6 of these men achieved lasting erections sufficient for intercourse. The other 2 had erections that lasted ten minutes and were considered to have venous leak impotence. All patients with Peyronie disease had tumescence after papaverine injection, but in 5 the penis became rigid only at the base. Complications of papaverine injection were uncommon and minor. The Rigiscan and papaverine are useful in the diagnosis and management of erectile impotency.
