Abstract
Context: Intravesical prostatic protrusion (IPP) is a potential candidate for the initial evaluation of patients with lower urinary tract symptoms (LUTS). Intravesical prostatic protrusion is also known to predict the outcome of trials without a catheter and medical treatment outcomes and to determine bladder outlet obstructions. Objectives: This study aimed to determine whether IPP influences the residual LUTS after surgery in patients with benign prostate hyperplasia who have undergone prostate surgery. Evidence Acquisition: An online database search was conducted regarding the prognosis of postoperative benign prostate hyperplasia patients with intravesical prostatic protrusions. The selected databases comprised PubMed, ScienceDirect, EBSCO, and Cochrane Library. Randomized controlled trial, cohort, or case control studies that were written in English or Bahasa and published up until November 2020 were included. We reviewed postoperative outcomes, including subjective symptoms, based on the International Prostate Symptom Score and objective signs, such as Qmax and post voiding residue. Results: Our initial database search yielded 143 papers. After exclusion from abstract screening, seven papers were considered for full-text analysis. Five of these studies showed higher preoperative intravesical prostatic protrusion within successful postoperative outcomes. Some studies showed that patients with significant intravesical prostatic protrusions had more significant International Prostate Symptom Score decrements. However, two studies demonstrated that intravesical prostatic protrusion was not a significant prognostic factor. Conclusions: Most studies suggested that intravesical prostatic protrusion can predict better post-surgery lower urinary tract symptom outcomes. Further research using information about the risk of bias in ultrasound examination and more homogeneous surgical techniques and considering the duration of patients’ illness before they receive surgical management is needed.

Abstract
PURPOSE To evaluate the association of intravesical prostatic protrusion (IPP) and overactive bladder (OAB) in male patients with lower urinary tract symptoms (LUTS). IPP has been suggested to correlate with storage symptoms in addition to bladder outlet obstruction. METHODS This was an open-labeled, single-center, prospective study involving 128 men older than 40 years presenting with LUTS. We analyzed the relationship of IPP with age, prostate volume, uroflowmetry, post-void residual urine volume (PVR), International Prostate Symptom Score (IPSS), urgency severity scale (USS), and OAB symptom score (OABSS). The patients with an urgency score of ≥ 2 (OABSS question 2) and sum score of ≥ 3 were considered to have OAB. IPP was measured in the mid-sagittal section using transrectal ultrasound. The degree of IPP was classified as grade 1 (≤ 5 mm), grade 2 (> 5-10 mm), and grade 3 (> 10 mm). RESULTS The mean age of the patients was 64.9 ± 9.2 years, and 101 patients were diagnosed with OAB (79%). Mean IPPs were 2.4 ± 1.4 mm (grade 1, n = 77), 7.6 ± 1.4 mm (grade 2, n = 27), and 14.8 ± 4.4 mm (grade 3, n = 24). IPP was positively correlated with age, prostate size, PSA, PVR, and OABSS nocturia subscore, but not correlated with the presence or severity of OAB. Areas under the receiver-operating characteristic (ROC) curves for the diagnosis of OAB were 0.807 and 0.604 for IPSS-storage subscore and IPP, respectively. CONCLUSION IPP is not a good predictor of OAB in men presenting with LUTS. However, grade 3 IPP indicates higher frequency of nocturia.

Abstract
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.

Impact of intravesical protrusion of the prostate in the treatment of lower urinary tract symptoms/benign prostatic hyperplasia of moderate size by alpha receptor antagonist. Int Neurourol J 2012; 16:187-90. [PMID: 23346485 PMCID: PMC3547180 DOI: 10.5213/inj.2012.16.4.187] [Citation(s) in RCA: 14] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/01/2012] [Accepted: 12/13/2012] [Indexed: 11/08/2022] Open
Abstract
PURPOSE To evaluate whether intravesical protrusion of the prostate (IPP) is related to the treatment effect of alpha-1 receptor antagonist in patients with lower urinary tract symptoms (LUTS)/benign prostatic hyperplasia (BPH) with a prostate size of less than 40 g. METHODS A total of 77 BPH patients over 50 years of age treated with alfuzosin (alpha blocker) were enrolled prospectively. The study included only patients with BPH of 40 g or less. The patients were classified into two groups depending on the presence of IPP at baseline: the IPP group (41 patients) and the non-IPP group (36 patients). Prostate volume, prostate-specific antigen (PSA), International Prostate Symptom Score and quality of life (IPSS/QoL), maximum flow rate (Qmax), and postvoid residual (PVR) volume were compared between the groups. The clinical significance of IPP was evaluated after the patients had been taking alfuzosin for 8 weeks. RESULTS PSA and IPSS (total and voiding subscore) showed significant correlations with IPP (P<0.05). Comparison of parameters before and after 8 weeks showed that alfuzosin improved the total IPSS and all subscores (P<0.001), QoL (P<0.001), Qmax (P<0.001), and PVR (P=0.030) in the non-IPP group. CONCLUSIONS Alfuzosin may be less effective in improving symptom scores, PVR, and Qmax in the treatment of LUTS/BPH in the presence of IPP.

Abstract
Purpose To evaluate the significance of intravesical prostatic protrusion (IPP) for predicting postoperative outcomes in patients with benign prostatic hyperplasia. Materials and Methods A total of 177 patients with a possible follow-up of at least 6 months who were treated with transurethral resection of the prostate (TURP) were analyzed. We divided the patients into two groups on the basis of the degree of IPP: the significant IPP group (IPP≥5 mm, n=74) and the no significant IPP group (IPP<5 mm, n=103). We analyzed postoperative changes in parameters, such as the International Prostate Symptom Score (IPSS), IPSS quality-of-life (QoL) score, maximum urinary flow rate (Qmax), and postvoid residual urine (PVR). The IPSS was subdivided into voiding (IPSS-v) and storage (IPSS-s) symptoms. Multivariate logistic regression analysis was performed to identify whether IPP could predict surgical outcomes of TURP. Results Preoperative parameters were not significantly different between the two groups except for total prostate volume and transitional zone volume. Postoperative changes in IPSS, IPSS-v, IPSS-s, and QoL score were higher in the significant IPP group than in the group with no significant IPP. Changes in Qmax and PVR were not significantly different between the two groups. Multivariate logistic regression analysis (after adjustment for age, prostate-specific antigen level, total prostate volume, and transitional zone volume) revealed that the odds ratios (95% confidence interval) of decreased IPSS and IPSS-s in the significant IPP group were 3.43 (1.03 to 11.44) and 3.51 (1.43 to 8.63), respectively (p=0.045 and 0.006, respectively). Conclusions Significant IPP is an independent factor for predicting better postoperative outcomes of IPSS and IPSS-s.

Abstract
PURPOSE The prostatic urethra is a bent tube, and the clinical significance of the prostatic urethral angle (PUA) was recently reported. We investigated the statistical significance of an increased PUA on the International Prostate Symptom Score (IPSS) in men with benign prostatic hyperplasia (BPH)/lower urinary tract symptom (LUTS). MATERIALS AND METHODS A retrospective analysis was done of 270 men with BPH/LUTS from July 2009 to June 2011. Prostate volume, PUA, and intravesical prostatic protrusion (IPP) were measured by transrectal ultrasonography (TRUS). The IPSS was analyzed separately as storage and voiding symptom score. In order to minimize the effect of prostate size on voiding, patients with prostate size over 40 ml were excluded. RESULTS The mean age was 62.0±9.3 years. The mean prostate volume was 29.0±5.5 ml (range, 20 to 40 ml), and median PUA and IPP were 34° (range, 12 to 52°) and 1.7 mm (range, 0 to 5.3 mm), respectively. The mean IPSS, mean IPSS-ss, and mean IPSS-vs were 19.0±8.2, 7.3±4.0, and 11.6±5.5, respectively. The prostate volume had no statistically significant correlation with IPSS, IPSS-ss, or IPSS-vs. IPP had a statistically significant correlation with IPSS (p<0.001), IPSS-ss (p<0.001), and IPSS-vs (p<0.001). PUA had no statistically significant correlation with IPSS or IPSS-ss. However, PUA had a significant correlation with IPSS-vs (p=0.047). Comparing a higher PUA (≥34°) with a lower PUA (<34°), patients with a higher PUA had a higher IPSS (p=0.001) and a higher IPSS-vs (p=0.001). There was no significant difference in IPSS-ss, prostate volume, or PSA between the two groups. CONCLUSIONS IPP showed significantly correlated with the IPSS and voiding symptom score was affected by the PUA but not by the prostate volume. As the PUA increased, the patients' voiding symptoms worsened. Further study may be needed.

Abstract
Purpose To analyze the effectiveness of tamsulosin 0.2 mg once daily for 3 months according to the degree of intravesical prostatic protrusion (IPP) in patients with benign prostatic hyperplasia (BPH). Materials and Methods A total of 134 BPH patients over 40 years of age treated with tamsulosin 0.2 mg between January 2007 and January 2009 were enrolled retrospectively. The patients were classified into three groups according to the degree of IPP: below 5 mm (group A), between 5 and 10 mm (group B), and over 10 mm (group C). Prostate volume, prostate-specific antigen (PSA), prostatic urethral length (PUL), and prostatic adenoma urethral length (PAUL) were evaluated before treatment. International Prostate Symptom Score and Quality of Life (IPSS/QoL), maximal urine flow rate (Qmax), and postvoid residual (PVR) volume were measured before treatment, and improvement in the three groups was compared after 3 months. Results The mean age of the patients was 65.01±7.38 years. Mean IPPs were 0.90±1.39 mm (group A, n=90), 6.92±1.10 mm (group B, n=24), and 16.60±4.06 mm (group C, n=20). Prostate volume, PUL, PAUL, PSA, Qmax, and PVR showed significant correlations with IPP (p<0.05), but not with IPSS/QoL score (p>0.05). Comparison of parameters before and after 3 months showed that medication improved total IPSS and subscores (p<0.001), QoL (p<0.001), Qmax (p<0.001), and PVR (p=0.030) in group A. In group B, it improved total IPSS (p=0.01), irritative subscore (p<0.001), and obstructive subscore (p=0.03). In group C, only total IPSS (p=0.01) and irritative score (p<0.001) were significantly improved. Conclusions Tamsulosin may be more effective in improving symptom scores and Qmax in patients with mild IPP than in those with moderate or severe IPP.

Abstract
Purpose Male overactive bladder (OAB) may be caused by prostatic pathologies such as bladder outlet obstruction (BOO). Intravesical prostatic protrusion (IPP) has been found to correlate with BOO and acute urinary retention. We investigated the interrelation between male OAB symptoms and IPP for estimating anatomical changes to the prostate. Materials and Methods We assessed 179 consecutive men aged >40 years who presented with lower urinary tract symptoms. The initial evaluation included International Prostate Symptom Score (IPSS) and quality of life assessments, transrectal ultrasonography (TRUS), uroflowmetry, and postvoid residual urine volume. The degree of IPP was determined by the distance from the tip of the protrusion to the circumference of the bladder at the base of the prostate gland. Patients with IPP <0.5 cm were defined as group A (n=114), and patients having 0.5 cm≤IPP<1 cm were defined as group B (n=38). The others were defined as group C (n=27). Results A total of 51 patients complained of urgency in group A, 38 patients in group B, and 27 patients in group C. Likewise, 14 patients had a history of acute urinary retention in group A, 8 patients in group B, and 16 patients in group C. IPP grade had a statistically significant relation with both OAB and a history of acute urinary retention. Conclusions The results of our study have shown that male OAB is correlated with IPP. However, larger scale studies are needed to confirm these results.

Abstract
PURPOSE Transrectal ultrasonography (TRUS) is a non-invasive modality widely used in urology on an outpatient basis to measure the volume and anatomical structure of the prostate. However, the prostate volume measured by TRUS often varies from test to test. The aim of this study was to determine the clinical significance of the different shapes of the prostate, as shown by TRUS before and after transurethral resection of the prostate (TURP). MATERIALS AND METHODS We evaluated 103 patients who underwent TURP. TRUS was performed preoperatively, and the International Prostatic Symptom Score (IPSS) and quality of life (QoL) were assessed preoperatively and at 6 months postoperatively. Patients were classified into two groups: patients with a bilaterally enlarged transitional zone were assigned to group A, and those with a protruding retrourethral zone were assigned to group B. RESULTS There were no statistically significant differences between the two groups in preoperative variables. However, postoperative IPSS scores were lower in group A than group B (9.87+/-6.15 vs. 13.18+/-8.07, p=0.02). With regard to postoperative IPSS scores relative to preoperative IPSS scores, both groups showed a significant decrease, but group A experienced a significantly greater decrease than group B (13.43+/-7.47 vs. 8.67+/-8.33, p=0.005). CONCLUSIONS Patients with a prostate protruding into the bladder have less of a decrease in their IPSS scores after TURP, compared to patients that do not have prostate protrusion, meaning that patients with protrusion experience less symptomatic relief.
