Week 11- Male Pelvis Flashcards
Reproductive duct that extends from the epididymis the the ejaculatory duct
Vas deferens
Superior portion of the prostate gland, which is located below the inferior margin of the urinary bladder
base
Inferior portion of the prostate gland, which is located superior to the urogenital diaphragm
apex
A longitudinal ridge within the prostatic urethral wall where the orifices of the ejaculatory ducts are located on either side.
verumontanum
Demarcation between the inner gland and the outer gland, which normally appears hypochoic.
surgical capsule
Duct that passes through the central zone and empties into the urethra; originates from the combination of the vas deferens and the seminal vesicle.
ejaculatory duct
Describe the transrectal sonographic technique used to evaluate the prostate gland, including patient preparation, positioning,, image orientation, and any contraindications to the study.
The most common approach is the endorectal approach because it results in improved visualization of the gland and surrounding structures. The patient’s bladder must be empty. The patient is placed in the left lateral decubitus position with the knees bent into the chest. Gel and a probe cover are placed over the probe and lubricating gel is applied to the probe. The transducer is then inserted into the rectal cavity. The ultrasound image is inverted during a prostate examination with the near field at the bottom of the image and the far field at the top. In the transverse plane, the right lobe of the gland is at the left side of the image and the left lobe of the gland is on the right side. In the sagittal plane, the base of the gland is at the left side of the image and the apex of the gland is at the right side of the image. Contraindications include rectal fissures, rectal tumors, thrombosed hemorrhoids, and prostatitis, which may prevent insertion of the probe due to patient discomfort
