“…They described two parenchymal groups of arteries, urethral and capsular. The color flow signals in the lesions described in their article are mostly supplied by the capsular group of arteries [14]. In studies with CDUS, objective grading of the amount of flow signal is difficult and is different from paper to paper.…”

“…The urethral arteries, conversely, course parallel to the prostatic urethra after they enfold into the prostate at the bladder neck. 3 In this study, it was found that the mean value and geometric mean were higher for mean PI, mean RI, PSV and S/D in the malignant group than in the benign group, but none of the parameters were found statistically significant between the benign and the malignant groups. Huang and Hsieh 4 also showed that high-grade prostate cancer tends to have higher RI.…”

Objectives: To compare the transrectal (TR) spectral Doppler findings between benign prostatic hyperplasia group and prostate cancer group. Methods: All the patients were assessed for adequate preparation, and informed consent was obtained prior to the procedure. The control group (n 5 33) comprised patients who were negative for malignancy on biopsy. The study group (n 5 22) were positive for malignancy and were also divided into three groups on the basis of the Gleason score. Study parameters included mean values for resistive index (RI), pulsatality index (PI), systolic/diastolic ratio (S/D) and peak systolic velocity (PSV). These were separately measured for bilateral capsular and urethral branches and compared between groups. In patients with unilateral tumour, these were compared between the tumour and non-tumour sides. Finally, the parameters were compared with patient's age. MannWhitney U test was used to evaluate the statistical significance. Results:The mean values of RI, PI, S/D and PSV were found to be 0.84/1.03, 1.8/1.99, 3.93/4.45 and 15.52/ 16.15 cm s 21, respectively, in the control and study groups which were not statistically significant. In patients with unilateral malignancy (n 5 16), there was no significant difference from the non-tumour side. Doppler parameters showed statistically significant relationships with age. The mean of minimum RI was found to be 0.60 in patients less than 60 years of age and 0.76 in patients more than or equal to 60 years of age in the benign category (p-value 5 0.014). The PI and S/D also showed significant difference in the benign category. Conclusion: TR spectral Doppler parameters did not reveal any significant difference in patients with or without prostatic malignancy, irrespective of the Gleason grade. Doppler parameters, however, showed significant correlation with age and were lower in younger patients. Advances in knowledge: TR spectral Doppler is unlikely to emerge as a diagnostic and prognostic tool for prostate carcinoma.

“…The prostatic vasculatures at bilateral NVB sites were analyzed in the largest transverse section of the prostate (Fig. 1) in accordance with reports by Leventis and colleagues 14 and Neumaier and colleagues 15 The arteries at the NVB sites were examined at the point just before they entered the prostate, rather than the intraprostatic branches penetrating into the gland. Once the pulsatile waveforms of a given Doppler spectrum became stable for the consecutive five repeats, the peak-systolic velocity (PSV), enddiastolic velocity (EDV), and the resistive index (RI) of each site were measured and recorded.…”

Introduction and Objectives: There is a need to improve prescreening determination of prostate cancer to better select patients who need biopsy. Such a strategy properly implemented, will decrease the number of negative biopsies for prostate cancer and in turn better balance the risks and morbidity for patients recommended for biopsy. The aim of study is to investigate Doppler spectral waveform parameters of neurovascular bundle (NVB) vessels and determine differences between benign and malignant pathologies. Patients and Methods:We performed a prospective analysis involving 292 patients who received prostate biopsy for elevated prostate-specific antigen (PSA) values or abnormal digital rectal examination, as well as 174 patients with symptomatic benign prostatic hyperplasia. Doppler spectral waveform (DSW) parameters (peaksystolic velocity [PSV], end-diastolic velocity [EDV], and resistive index [RI]) were measured at bilateral NVB vessels through Doppler transrectal ultrasound at the right lateral decubitus position, compared, and analyzed among patients with benign versus malignant histology for each side. Results: Overall, both PSV and EDV at malignant sides were significantly higher than those at benign sides, as well as lower RI (all p-values < 0.05, unpaired t-test). In subgroup analysis with 93 patients of serum PSA between 10 and 20 ng/mL and 56 patients with one-side malignancy, higher EDV and lower RI were significantly associated with malignancies (all p < 0.05). The values of PSV and EDV rather than RI might be influenced by the patients' position and RI by the prostate volume. Conclusions: In this study, DSW parameters (mainly EDV and RI) at NVB vessels were significantly associated with prostate cancer, particularly in patients with serum PSA of 10-20 ng/mL. It should be in caution that the patients' position and prostate volume may influence the Doppler signal as demonstrated in the current study. These findings can provide more diagnostic information before prostate biopsy.

Normal prostate gland: examination with color Doppler US.

Abstract: Transrectal color Doppler US can depict the vascular anatomy of the prostate gland. Knowledge of the normal vascular appearance of the gland should aid in the differentiation of normal from abnormal findings.
