Post-prostatectomy impotence.
With the help of the principles of rapid eye movement sleep and nocturnal penile tumescence, 14 patients who underwent transurethral prostatectomy were studied by monitoring the electroencephalograph, electro-oculograph and penile plethysmograph activity preoperatively and postoperatively. No instance of complete loss of penile erection was found postoperatively. The need for objective rather than subjective data is emphasized.
