Correlation Between Prostatic Urethral Angle and Bladder Outlet Obstruction Index in Patients With Lower Urinary Tract Symptoms

Clinical significance of prostatic-urethral angulation on the treatment outcome of patients with symptomatic benign prostatic hyperplasia treated with tamsulosin hydrochloride

“…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). The reason for this difference between our study and others may be the selection of our patients.…”

“…At baseline evaluation (pre-treatment), no difference in the IPSS/QoL score was found between both groups (P-value = 0.68 and 0.09 respectively) ( Table 1). These findings are similar and agree with previous reports (12)(13). At 2 months of follow-up our study showed a statistically significant improvement in the IPSS/QoL scores in group A compared to group B (P-value = 0.0005 and < 0.000 respectively) ( Table 2).…”

“…The PUA cutoff value in previous studies was 35˚; at this angle a significant difference in clinical symptoms and urodynamics parameters in patients and healthy men were found. Subsequently, we classified our patients into 2 categories (PUA ≤ 35º and PUA > 35º) based on these studies (11)(12). All patients received medical treatment in the form of tamsulosin hydrochloride 0.4 mg once daily for 8 weeks.…”

“…Recently, Cho et al introduced the term prostatic-urethral angulation (PUA) as a new measurement that could be a causal factor for BPH (10), and in their subsequent preliminary clinical study using the fluid dynamic model, they reported that the urinary flow rate decreased by more than 27% as the PUA increased from 35° to 90° (11). 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).…”

Peut-on évaluer le débit urinaire maximal et le résidu postmictionnel par l’échelle visuelle analogique (EVA) ? Une étude prospective chez 31 patients

“…L'étude « pressiondébit » est l'examen de référence recommandé par l'ICS pour l'exploration de l'obstruction sous-vésicale [4]. Plusieurs méthodes ont été proposées pour évaluer l'obstruction sous-vésicale de façon non invasive (épaisseur de la paroi vésicale, angle urétral, index de protrusion prostatique…) [7][8][9][10][11]. Cependant, aucune étude ne s'est intéressée à l'éva-luation subjective du débit urinaire isolé tel qu'il est perçu par le patient.…”
