Transrectal ultrasound- normal seminal vesicles (variants) and normal anatomy of vas deferens:
(added - 10th July 2007)
(a septate appearance)
Transurethral resection of the prostate (TURP):
(added- 9th April 2007)
In this TRUS sonographic image, the defect due to a Trans-Urethral Resection of the Prostate, is evident. Here, the transition zone of the prostate has been resected. The transition zone is the seat of the benign hyperplasia of the prostate, and is a part of the “inner gland”.
Prostatic carcinoma and TRUS imaging:
TRUS (transrectal ultrasound) imaging of the prostate is very important to diagnose as well as grade prostate carcinoma. 70% of prostatic cancers occur in the peripheral zone of the prostate. This 70 yr. old male patient had a large hard nodule palpable on digital rectal examination. TRUS ultrasound images (transverse and para-sagittal) show a typical hypoechoic lesion of 16 mm. in the left peripheral zone. There is no obvious breach of the prostatic capsule or the surgical capsule. No obvious involvement of the seminal vesicles is seen. There is also evidence of benign prostatic hypertrophy with significant intravesical enlargement.
Diagnosis: prostate carcinoma with Benign hypertrophy.
This is a middle aged male patient who complained of dysuria
and pyrexia of unknown origin (PUO).
He was referred for an ultrasound of the prostate.
TRUS scan shows a hypoechoic collection of 2.5 cms within the right lobe
of the prostate. The walls of the lesion are shaggy s/o an abscess.
Marked tenderness was present in this region on probe pressure.
The seminal vesicles were engorged and measured almost
19mm. to 21 mm. in width.
DIAGNOSIS: PROSTATIC ABSCESS.

PROSTATIC UTRICLE CYST:
This is a 32 year old young male, with complaints of dysuria.
The transabdominal image (A) shows a doubtful, hypoechoic lesion in the prostate.
The TRUS (TRANSRECTAL ULTRASOUND) image (B) shows a transverse section
through the prostate. Image (C) shows the same cyst in a sagittal section.
Observe the close relation of the midline cyst to the prostatic urethra.
The cyst measures typically 11 x 8 mm.
These findings suggest prostatic utricle cyst.
Other cysts of prostate: Mullerian duct cysts, ejaculatory duct cysts,
cystic degeneration of benign hyperplasia of prostate, cavitary
prostatitis, retention cysts and prostatic abscess.
