Benign prostatic hyperplasia (BPH) is a common condition in middle-aged and older
men and negatively affects the quality of life. An ultrasound classification for
BPH based on a previous pathologic classification was reported, and the types of
BPH were classified according to different enlargement locations in the prostate.
Afterwards, this classification was demonstrated using magnetic resonance imaging
(MRI). The classification of BPH is important, as patients with different types
of BPH can have different symptoms and treatment options. BPH types on MRI are as
follows: type 0, an equal to or less than 25 cm3 prostate showing little or no
zonal enlargements; type 1, bilateral transition zone (TZ) enlargement; type 2,
retrourethral enlargement; type 3, bilateral TZ and retrourethral enlargement;
type 4, pedunculated enlargement; type 5, pedunculated with bilateral TZ and/or
retrourethral enlargement; type 6, subtrigonal or ectopic enlargement; type 7,
other combinations of enlargements. We retrospectively evaluated MRI images of
BPH patients who were histologically diagnosed and presented the different types
of BPH on MRI. MRI, with its advantage of multiplanar imaging and superior soft
tissue contrast resolution, can be used in BPH patients for differentiation of
BPH from prostate cancer, estimation of zonal and entire prostatic volumes,
determination of the stromal/glandular ratio, detection of the enlargement
locations, and classification of BPH types which may be potentially helpful in
choosing the optimal treatment.
