Structural Variations of the Prostatic Urethra Within the Prostate Predict the Severities of Obstructive Symptoms: A Prospective Multicenter Observational Study

Structural differences of prostate related to prostatic urethra as reflected by rPUL were found to be significantly correlated with the severity of voiding symptoms. This finding suggests structural change of the prostatic urethra inducted by prostate enlargement underlies the development of male LUTS.
