Combination of intravesical prostatic protrusion and resistive index is useful to predict bladder outlet obstruction in patients with lower urinary tract symptoms suggestive of benign prostatic hyperplasia

Abstract

Intravesical prostatic protrusion and resistive index are useful parameters for predicting bladder outlet obstruction in patients with lower urinary tract symptoms suggestive of benign prostatic hyperplasia. In clinical practice, the combination of intravesical prostatic protrusion and resistive index on ultrasound can be diagnostic of bladder outlet obstruction.

Association between metabolic syndrome and intravesical prostatic protrusion in patients with benign prostatic enlargement and lower urinary tract symptoms (MIPS Study)

“…The presence of median lobe enlargement implies that dyskinetic smooth muscle contraction occurs during micturition [25]. Kyung et al [26], in a longitudinal analysis during a 5-year period, showed that changes in weight and MetS status were significantly associated with the prostate growth rate.…”

Clinical Considerations for Intravesical Prostatic Protrusion in the Evaluation and Management of Bladder Outlet Obstruction Secondary to Benign Prostatic Hyperplasia

“…IPP has shown a positive predictive value of 72% for BOO [11]. In fact, the positive predictive value of the combined parameters IPP and resistive index of the prostatic capsular artery increases to 83.8% [12]. Because this resistive index is a signal of vascular resistance [13], it is a good indicator for BPH-related BOO (12).…”

Editorial Comment to From evidence‐based medicine to evidence‐balanced medicine for individualized and personalized care: As applied to benign prostatic hyperplasia/male lower urinary tract symptoms

“…1 The IPP is a comparatively recent tool, but several authors have pointed out the efficacy of this new index for evaluating the severity of BPH/LUTS as well as for post- robot-assisted laparoscopic radical prostatectomy urinary incontinence. [2][3][4] This new index assesses not only prostate size, but also prostate shape and relationship with the bladder neck and the internal ostium of the urethra. We can expect use of the IPP to spread, and more research of this type should be undertaken as well.…”

“…The present study by Foo proposes using the intravesical prostatic protrusion (IPP) degree and the presenting severity for staging therapeutic strategies for BPH/LUTS based on evidence‐balanced medicine for individualized and personalized care .
