Background: Intravesical prostatic protrusion (IPP) is a manifestation of benign prostatic hyperplasia marked by overgrowth of the prostatic median lobe into the bladder, producing bladder outlet obstruction and related storage and voiding symptoms. Methods: A MEDLINE® database search of the current literature was guided using combination of “prostate” with the following terms: intravesical prostatic protrusion, bladder trabeculation, bladder outlet obstruction, lower urinary tract symptoms, alpha blockers, transrectal ultrasonography, and prostatectomy. Results: Although IPP can be identified via a variety of imaging modalities, it is easily detected via transrectal ultrasonography (TRUS). Failing to detect IPP promptly by TRUS may result in refractory symptoms of benign prostatic hyperplasia, as the condition may not respond to typical α1-adrenoceptor antagonist therapy. In addition, depending on grade, IPP can influence outcomes and complications of prostatectomies. Conclusion: Upon report of lower urinary tract symptoms, initial performance of TRUS along with digital rectal examination prevents delay in the appropriate evaluation and management of prostatic diseases.

In this review, we have looked at three important areas in understanding male lower urinary tract symptoms. These are improvement in terminology, detrusor underactivity, and nocturia. Benign prostatic hyperplasia leading to bladder outlet obstruction has been covered in a previous review.

Objective: We investigated the correlation of the PUA on clinical parameters and bladder outlet obstruction (BOO) in men with lower urinary tract symptoms (LUTS) suggestive of benign prostatic hyperplasia (BPH). Material & Method: This study was performed between January to April 2011. A cross sectional analysis of 24 men with LUTS associated BPH aged > 50 years was performed. Patients underwent evaluation including International Prostatic Symptom Score (IPSS), transrectal ultrasonography, uroflowmetry, and pressure-flow study. Statistical analysis was performed to evaluate correlation of the PUA on clinical parameters and bladder outlet obstruction (BOO). Results: A total of 24 patients, aged 51 to 78 years were enrolled in this study. The mean value of total IPSS, prostate volume, PUA, and Qmax was 22 (range 7-35), 34,4 cm3 (range 21–70 cm3), 37,3° (range 25°–55°), and 10,5 mL/s (range 4,2–17,9 mL/s), respectively. Pearson’s correlation analysis showed that PUA was not significantly correlated with IPSS (p = 0,117), Qmax (p = 0,434), total prostate volume (p = 0,213). Patients with increased PUA (PUA > 35°) had higher incidence and degree of BOO (p < 0,05). Conclusion: PUA may be one method to assess the presence of BOO in men with LUTS associated BPH. Our investigation suggest that PUA may help in the treatment of individuals by better predicting their likely classification from a pressure-flow study.Keywords: Prostatic urethral angle, benign prostatic hyperplasia, lower urinary tract symptoms, bladder outlet obstruction.
