[Correlation of prostate peripheral zone thickness with benign prostatic hyperplasia/ lower urinary tract symptoms: An update].

BPH is a most common benign disease causing dysuria in old and middle-aged males. Studies show that the total prostate volume (TPV) is not necessarily correlated with the severity of lower urinary tract symptoms (LUTS). All BPH hyperplastic nodules occur in the prostate transitional zone and the glandular region around the urethra. Therefore, there are few clinical studies on the correlation between the peripheral zone thickness (PZT) of the prostate and BPH/LUTS. Relevant literature on the correlation between PZT and BPH/LUTS published at home and abroad in recent years indicate that PZT is a novel, simple, economical, reliable and simple measurement of prostate parameters independently associated with urinary tract symptoms in patients with BPH and will be a new factor in the evaluation and management of male BPH/LUTS. However, further research is needed to clarify the clinical utility of PZT in place of invasive urodynamic testing, and its applicability to the BPH patients in China more has to be certified by more clinical and prospective studies.
