  9. During the course of surgery for benign prostatic hypertrophy (benign enlargement of the prostate tissue which occludes the prostatic urethra) an electrical cutting device is inserted into the penile, then prostatic urethra, to remove the hypertrophic tissue.

    Is well imaged radiologically using an intravenous urogram
    Is extraperitoneal
    B and D
  11. During a vasectomy, the ductus deferens is ligated in the superior part of the scrotum. Two months following this sterilization procedure, the subsequent ejaculate contains:

    Seminal fluid and prostatic fluid
    Sperm only
    Sperm and seminal fluid
    Sperm, seminal fluid, and prostatic fluid
  12. An elderly male patient presents with dysuria and urgency. You suspect benign prostatic hypertrophy which has caused an enlargement of the:
    interureteric crest
    prostatic utricle
    seminal colliculus
    sphincter urethrae
    uvula
  13. An elderly patient is having difficulty in voiding (urinating). He complains that after voiding, he still feels as though he needs "to go" again. You suspect that this patient suffers from benign prostatic hypertrophy, which has caused enlargement of the __________ of the bladder.
    seminal colliculus
    interureteric crest
    ampulla
    trigone
    uvula
  14. The prostate gland:
    encircles the urethra

    Femoral nerve
    Hypogastric nerve
    Internal pudendal artery
    Obturator artery
    Pelvic splanchnic nerves
  16. A structure which is homologous to the male scrotum:
    Labia minora
    Labia majora
    Glans
    Shaft of corpus cavernosum
  17. The male pelvis tends to differ from the female pelvis in that the male pelvis often has a:

    smaller subpubic angle
    straighter sacral curvature
    larger pelvic outlet
    rounder pelvic inlet
  18. The boundaries of the perineum include all the following except:
