Task: Answer Verification
Input (English): Question: Is penile Doppler ultrasound in men with stuttering priapism and sickle cell disease -- a labile baseline diastolic velocity a characteristic finding?
Answer: Men with SP had a unique baseline Doppler ultrasound waveform, with a low PR waveform and an elevated, variable cavernosal artery velocity. We propose that this may be the sonographic manifestation of a reduced, fluctuating smooth muscle tone and that PDU may have a role for diagnosis and therapeutic monitoring of SP.
Output (English): yes
