- Abstract
Objective: The purpose of this study is to demonstrate that intravesical prostatic protrusion (IPP) is closely related to the degree of obstructive lower urinary tract symptoms, prostate size and residual urine volume. Methods: Male patients were identified with low urinary obstructive symptoms due to benign prostatic enlargement. The sample included 69 male patients aged between 50 and 79 years old, diagnosed with of benign prostatic hyperplasia, urinary obstructive symptoms from benign prostatic enlargement. Noninvasive methods for diagnosis, questionnaire International Prostate Symptom Score(IPSS), uroflowmetry to assess volume and peak micturition, transabdominal ultrasound to measure prostate volume, residual urine volume and intravesical prostatic protrusion was used in sagittal section. To identify exact cut point that can predict an altered Qmax value (< 15) a test ROC curve was performed to identify the value of 4.5 mm of intravesical protrusion as the point of greater sensitivity and specificity (62 and 69% respectively). Results: A significant linear correlation between intravesical protrusion and the IPSS (r = 0.41, p = 0.001) was found, as well as prostate volume (r = 0.30, p = 0.01) and Qmax (r = -0.29, p = 0.01). Finding no linear correlation between IPSS with prostate volume (r = 0.11, p = 0.34), IPSS with Qmax (r = -0.18, p = 0.13) nor with Qmax or prostate volume (r = - 0.11, p = 0.34). Trhough Roc curve, was found that the value of intravesical prostatic protrusion was 4.5 mm as the greater point of sensitivity and specificity (62 and 69 % respectively). A significant difference of patients with altered Qmax (< 15) was found, when they had a high prostatic protrusion (= 4.5mm). Conclusions: IPP is a useful parameter that correlates to the lower urinary tract obstruction in relation to Qmax, this can be used as a variable in the initial assessment of patients with obstructive lower urinary tract symptoms. The degree of IPP can guide the value of Qmax, nevertheless, it does not replace uroflowmetry.
