“…Chia et al reported that IPP of >16 mm was associated with a higher BOO index. A greater length of IPP was also related to a lower response to medical treatment including α ‐blockers and dutasteride . Mariappan et al noted that patients with greater IPP had a lower success rate of decatheterization after acute urinary retention.…”

“…It can be examined non‐invasively by transabdominal ultrasonography. IPP has been known as a predictor of efficacy not only for medical treatment such as an α‐1 blocker and dutasteride but also for surgical intervention . The IPP, however, is not always the same shape because the middle lobe and/or lateral lobes sometimes protrude into the bladder.…”

“…They enrolled 218 patients for 6 months or more on a combination medical therapy. During follow up 21% needed surgical intervention and IPP (odds ratio 1.133, p < 0.001) was the strongest independent factor predicting conversion to surgical intervention [22] .…”

Intravesical prostatic protrusion (IPP) has emerged as a new prostatic morphometric parameter of significance to aid the clinicians in various aspects of managing the patients with some diseases of the lower urinary tract and the prostate. These include but may not be limited to its role in such conditions as: bladder outlet obstruction, trial without catheter, medical treatment effect, progression of lower urinary tract symptoms related to benign prostatic hypertrophy (LUTS/BPH), risk factor for bladder stone in BPH, overactive bladder, prostate carcinoma, and early urinary continence recovery after laparoscopic radical prostatectomy. In this review, I will try to summarize the different researchers' efforts on the potential practical application of this clinical tool. Technology is ever evolving to help us in the diagnosis and management of our patients. However, we as clinicians should contemplate their cost and possible suffering for the patient by wise and judicious utilization based on our clinical experience and tools. IPP seems to be one such promising clinical tool.

“…Tamsulosin therapy may be more effective in improving IPSS and Q max in patients with mild IPP than in those with moderate or severe IPP [34]. Moreover, Hirayama et al [35] deduced that combination therapy (i.e., α 1 -blockers and dutasteride) has insufficient efficacy towards LUTS and/or BPH with severe IPP due to a low proportion of stromal components in the prostate. For these reasons, well-designed studies are needed to assess the effect of IPP on the scope of treatment.…”

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

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.
