TRUS imaging- some helpful hints

TRUS or transrectal ultrasound imaging is increasingly being used to investigate male infertility. The sonographic imaging of the prostate, vas deferens, seminal vesicles and ejaculatory ducts using TRUS is crucial in determing pathology of these parts of the male genito-urinary system. But often, the insertion of the endocavitary probe or Transrectal probe, causes considerable pain and hence non co-operation from the patient.
I have found this technique to be useful in almost all cases:
Ask the patient to breath in and out (deeply inspire and expire), and insert the transducer very slowly with each breath.
Another method: ask the patient to strain as though trying to defecate; this causes the anal sphincters to open and makes probe insertion easy.
