“…As a matter of fact they do not exclude patients with DO, creating a bias in the definition of the right predictive BWT cut-off value to define the presence of BPO. 6,27 We must also acknowledge some limitations of our study. This is the first retrospective analysis of a prospective collected database to test the possible association between DO and increased BWT in male patients, and therefore the findings may depend upon the enrolled population.…”

“…Our findings highlight one possible limitation of the current studies evaluating BWT or DWT for the prediction of BPO in male patients. As a matter of fact they do not exclude patients with DO, creating a bias in the definition of the right predictive BWT cut‐off value to define the presence of BPO …”

“…In addition, a study by Güzel et al suggested that the urinary bladder wall thickness (BWT) increases simultaneously with increasing urinary BOO. 14 The authors of this study showed that the measurement of BWT is a simple, fast and reproducible procedure predicting the severity of urinary BOO. Hakenberg et al revealed that men with LUTS and benign prostate enlargement presented with a moderate increase in BWT.…”

Prostate cancer is one of the most common neoplasms in elderly males in Europe and is rapidly becoming a major health burden throughout the world. Radical prostatectomy is a first-line treatment in the case of organ-confined prostate cancer and in selected cases of locally advanced disease. Recent studies have suggested that the urinary bladder wall thickness (BWT) is an important predictor of an overactive bladder (OAB). This article focuses on a hypothesis for the mechanism of urine incontinence in patients after radical prostatectomy due to urinary bladder hypertrophy. To verify the possible influence of changes in the urinary bladder structure on urine incontinence development, we designed an experiment in which patients with prostate cancer were qualified for radical prostatectomy. Our hypothesis that urinary bladder hypertrophy influences urine incontinence development in patients after radical prostatectomy may provide an insight toward the prevention and control of urine incontinence after surgery by oral pharmacotherapy or intravesical onabotulinumtoxinA injections in pre-radical prostatectomy mode.

“…There is considerable variation in the DWT cut‐off values used in previous studies investigating its use in the diagnosis of BOO: 3.25 mm in the study of Guzel et al, 5 mm in the study of Manieri et al, 2 mm in the study of Oelke et al, and 2.9 mm in the study of Kessler et al DWT measurement are greatly affected by the degree of bladder filling . However, no optimum cut‐off value of DWT has been defined in the literature thus far that can accurately predict BOO.…”

Objective: This study investigated whether the resistive index (RI) of prostate and bladder sonomorphologic parameters (total prostate volume [TPV], detrusor wall thickness [DWT], intraprostatic protrusion [IPP]) can be used instead of urodynamic studies (UDS) to predict bladder outlet obstruction (BOO) in benign prostatic hyperplasia (BPH) with lower urinary tract symptoms (LUTS). Methods: Men aged ≥50 years with clinical BPH/LUTS were prospectively enrolled included. Basic evaluations, measurement of sonomorphologic parameters, and UDS were performed in accordance with the International Continence Society's Good Urodynamics Practices protocol.Results: Data of 240 patients were divided into two groups based on the BOO index(BOOI).Group 1 consisted of patients negative for BOO (BOOI <40), whereas Group 2 consisted of patients positive for BOO (BOOI > 40). Patient age, International Prostate Symptom Score (IPSS), quality of life score and post-void residual volume were comparable between the two groups, whereas significant differences were evident in peak flow rate, TPV, DWT, RI, and IPP (P < 0.01 for all). Pearson correlation analysis revealed a significant correlation between BOOI and DWT (r = 0.198, P = 0.002), IPP (r = 0.450, P = 0.000), and RI (r = 0.334, P = 0.000). Multiple regression analysis revealed a significant correlation between BOOI and IPP (β = 0.382, P = 0.000) and RI (β = 0.226, P = 0.000). Receiver operating characteristic analysis showed that the area under curve was 0.785 for RI (95% confidence interval [CI] 0.703-0.867, P < 0.001) and 0.905 for IPP (95% CI 0.850-0.961, P < 0.001). At a cut-off value of 7.5 mm for IPP, the sensitivity was 86.9%, specificity was 83.3% and positive predictive value was 92.41%.Conclusion: IPP and RI may be the best non-invasive predictors for BOO in selected patients with LUTS/BPH.
