“…Our study showed no significant difference in Qmax values in the two groups of patients (p-value = 0.45) ( Table 1). In contrast to our findings, the urinary flow rate was found inversely associated with the PUA (11), and a larger PUA was associated with a lower urinary flow rate (14). On the other hand, no significant difference in Qmax values between patients with PUA more or less 35ẘ as reported (12).…”

“…Patients with PUA ≥ 35° had larger prostate volume and higher BOO index, in comparison with those who had PUA < 35° (12). Further studies showed that the PUA is significantly associated with maximum flow rate (Qmax) and voiding symptom scores in men with LUTS (13)(14). In terms of medical therapy for BPH several drugs are widely distributed in the market and selective α1-blocker is the recommended treatment (15).…”

“…We first suggested in 2008 that the PUA is a causal factor of LUTS/BPH based on a fluid dynamic model and mathematical simulation. Subsequently, we also showed that the PUA significantly associates with the Qmax and symptom scores in men with LUTS [8], [14], [15]. In a retrospective study of 270 LUTS/BPH patients by Park et al [16], an increased PUA is associated with an aggravation of voiding symptom.…”

“…The PUA was defined as the angle formed by 2 rays of both proximal and distal prostatic urethra on the midsagittal plane image, and which was taken with the posterior wall of the prostate positioned as flat as possible to minimize the influence of pressure from the rectal probe as shown in Fig. 2 [8], [12]. Two independent urologists (DHK and JYL) calculated the PUA, and the average of these two values was scored for greater accuracy.…”

“…LUTS secondary to BPH generally consists of three components: benign proliferation of the stroma and epithelium, bladder outlet obstruction and symptoms resulting from obstruction. 5 BPH has been considered to be one of the most important risk factors for LUTS; 6 however, it is becoming increasingly recognized that the origin of LUTS is multifactorial resulting from more than prostate enlargement. 7,8 We propose that the autonomic nervous system plays an important role in the development of LUTS.…”
