Abstract

Background: Ultrasound is the main method of exploring the prostate. In benign prostatic hyperplasia (BPH), it provides important morphological information and assesses its impact, helping to guide the treatment. Objective: To compare intravesical prostatic protrusion (IPP) and middle lobe volume by ultrasound in BPH. Method: This was a single center prospective, descriptive and analytical study, over a period of 6 months, including 95 patients, undergoing prostatic trans-abdominal ultrasound. Patients were selected by a single urologist for clinical suspicion of benign prostatic hypertrophy. The ultrasound examination was done by a single senior radiologist. Results: The mean age of the patients was 66.63 ± 11.55 years with ranges from 38 to 98 years. The prevalence of BPH was 76.84%. The rate of patient with middle lobe protrusion was 48.42%. The mean middle lobe volume was 11.29 ± 12.90 ml. More than half of the patients (50.91%) had an IPP stage 3 of. The mean bladder wall thickness was 6.08 ± 2.58 mm, with 50.53% being pathological. The post-voiding residue (PVR) was significant in 38.75% of patients. Renal repercussions were present in 17.89%. The correlation analysis did not note a statistical link between prostate volume and quality of life score (p > 0.05). There was a statistically significant correlation between IPP values and quality of life score (p = 00461), IPSS score (p = 0.0424) and PVR (p = 0.0395). For middle lobe volume, there was a correlation with PVR (p = 0.0018). There was no correlation with clinical impact (quality of life score and IPSS score). Conclusion: The IPP appears to be an easy element to measure and better than the volume of the prostate and the middle lobe in assessing the impact of BPH.

Highlights

Benign prostatic hyperplasia (BPH) is the most common prostate disease
The study concerned the trans-abdominal ultrasonography (TAUS) of intravesical prostatic protrusion (IPP) and middle lobe volume in a consecutive series of patients clinically suspected of having benign prostatic hyperplasia (BPH)
A middle lobe was noted in 55 patients, achieving a prevalence of 57.89% in patient with clinical suspicion of BPH

Summary

Introduction

Benign prostatic hyperplasia (BPH) is the most common prostate disease. Its frequency increases with age [1]. Its purpose is to provide morphological information on the prostate and to assess the importance of any impact on the upper urinary tract and to help in the selection of patients to determine the type of treatment according to the weight of the prostate, the importance of post-voiding residue (PVR) and the tissue composition of BPH [3]. In benign prostatic hyperplasia (BPH), it provides important morphological information and assesses its impact, helping to guide the treatment. Objective: To compare intravesical prostatic protrusion (IPP) and middle lobe volume by ultrasound in BPH. There was a statistically significant correlation between IPP values and quality of life score (p = 00461), IPSS score (p = 0.0424) and PVR (p = 0.0395). There was a correlation with PVR (p = 0.0018). Conclusion: The IPP appears to be an easy element to measure and better
