PCAR: presumed circle area ratio of the prostate; RIP: resistive index in the prostate; MHA: maximal horizontal area of seminal vesicles; PSV: peak systolic velocity in the flaccid penis; IPSS: international prostate symptom score; IIEF-5: the five-item version of the International Index of Erectile Function; PV: prostate volume; RW: resected prostatic weight; N: patient number; ^b: before TURP; ^a:12 months after TURP; *p < 0.05 indicates a significant difference; Data are expressed as mean ± SD; The Mann–Whitney U test was used for statistical analysis.
