Compared with the standard transrectal ultrasound-guided sextant biopsy
, MRI-targeted biopsies detect more intermediate/high-risk cancer using fewer biopsy cores and reduce overdetection of low-risk cancer.
In order to increase the cancer detection rate of prostate biopsy, various schemes have been applied in time such as sextant biopsy
, extended biopsy and saturation biopsy (9).
An ultrasound steered sextant biopsy
could also be advised.
Increasing prostate biopsy cores based on volume vs the sextant biopsy
: a prospective randomized controlled clinical study on cancer detection rates and morbidity.
The biopsy procedure was completed as a sextant biopsy
in left lateral decubitus position, using a 22-gauge needle accompanied by transrectal ultrasound.
Objective: To compare the diagnostic accuracy of power Doppler-guided targeted prostate biopsy and random sextant biopsy
in the diagnosis of prostate cancer.
All patients who had a sextant biopsy
at our institution were included.
 compared standard transrectal sextant biopsy
with an extended transperineal ultrasound-guided template prostate biopsy, obtaining an average of 18 cores.
Outcome of sextant biopsy
according to gland volume.
Thus, a prostate cancer diagnosis is typically made through TRUS-guided sextant biopsy
and histopathological examination.
We obtained specimens from 2400 prostate sextant biopsy
cases diagnosed between 1991 and 1997 from both academic and private-practice urologists.
Background: Targeted magnetic resonance (MR)/ultrasound fusion prostate biopsy has been increasingly used in the evaluation of patients with elevated prostate-specific antigen (PSA) following negative standard sextant biopsy
and in those patients considering active surveillance.
