Elastography of shift wave in diagnostics of prostate diseases
[Original research] [Urology]
Alexandr Bolotskov; Andrey Volkov; Mikhail Petrichko;
The aim was to assess capacity of elastography of
shift wave (ESW) in differential diagnostics of pros-
tate (P) diseases. 179 patients had undergone tran-
srectal ultrasound with color Doppler analysis (CDA)
and ESW. Threshold stiffness (rigidity) for the benign
tumor in peripheral zone of P is E <45 kPa. Increase
of rigidity of P transitory zones ≥ 35 kPa appeared to
be one of the criteria for assessment of the therapy
efficacy. E mean > 70 kPa in most of cases was as-
sociated with P cancer. Differential diagnostics be-
tween acute focal prostatitis and tumor requires ESW
in the dynamics.
