“…In contrast, both Keijzers et al [4]and Francisca et al [7]found that patients who were younger, and had higher symptom scores and lower peak uroflow rates at baseline, had a significantly higher retreatment rate, particularly receiving instrumental or invasive surgery. For prostate volume, there is some equivocation in the literature [4, 7, 11, 13]. In our study, there were no significant differences according to the patients’ age, symptom score, IPSS, peak uroflow rate or prostate volume among patients requiring no further therapy, receiving endoscopic surgery and medication.…”
