In benign prostatic hyperplasia (BPH), it provides important morphological information and assesses its impact, helping to guide the treatment. <strong>Objective:</strong> To compare intravesical prostatic protrusion (IPP) and middle lobe volume by ultrasound in BPH. <strong>Method:</strong> 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. <strong>Results:</strong> 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 (<em>p</em> > 0.05). There was a statistically significant correlation between IPP values and quality of life score (<em>p</em> = 00461), IPSS score (<em>p</em> = 0.0424) and PVR (<em>p</em> = 0.0395). For middle lobe volume, there was a correlation with PVR (<em>p</em> = 0.0018). There was no correlation with clinical impact (quality of life score and IPSS score). <strong>Conclusion:</strong> 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.展开更多

Symptomatic Benign prostatic hypertrophy may cause obstructive symptoms, irritative symptoms or both obstructive symptoms include a sensation of incomplete bladder emptying, straining to void, urinary hesitancy and weak stream while irritative symptoms include dysuria, nocturia, urinary frequency and urinary urgency. A quantitative measure of the severity of lower urinary tract symptoms due to benign prostatic hypertrophy can be obtained using the International Prostate Symptoms Score. Ultrasonography is useful for helping to determine bladder and prostate size in patients with urinary lower urinary tract symptoms. Uroflowmetry is a non-invasive test that assesses voiding function. It provides valuable data on the voided volume, time is taken to reach maximum flow rate and average flow rate. The goal of this study was to improve the follow up of patients with benign prostatic hypertrophy by providing simple, available, affordable and non-invasive that best predict bladder outlet obstruction and the quality of life in these patients. <strong>Method: </strong>This was a cross-sectional analytic study carried out over a period of five months from May 2020 to September 2020 at the Yaounde Gynaeco-Obstetric and Paediatric Hospital, which is a tertiary hospital in Cameroon. Were included in the study, adult males who presented with lower urinary tract symptoms and prostatic enlargement suggestive of benign prostatic hypertrophy taking into account clinical, uroflowmetry and ultrasound findings. <strong>Results:</strong> A study population of 103 participants was recruited. The mean age of patients was 63.17 ± 10.26 years. Concerning the International Prostate Symptoms Score, the mean total, voiding (obstructive) and storage (irritative) scores were 14.6 ± 6.2, 8.5 ± 4.1 and 6.05 ± 2.7 respectively. The mean maximum flow rate was 13.44 ± 3.88 mL/s. The mean prostate volume was 53.71 ± 16.46 ml. A majority of patients have an enlarged prostate 1.5 to 2 times (46 to 60 mL) the upper limit for normal value. The intravesical prostatic protrusion was present in eighty-three (80.58%) and absent in 20 (19.42%). Above a prostate volume of 60 mL, 91% to 100% of our patients had intravesical prostatic protrusion. There was strong evidence (p < 0.001) that a change from no intravesical prostatic protrusion to intravesical prostatic protrusion grade 1 increased the chances of having a low maximum flow rate with a crude odds ratio of 7.98. The adjusted odds ratio after multivariate analysis was 5.26 and this remained statistically significant (p = 0.03). <strong>Conclusion:</strong> the measure of intravesical prostatic protrusion is superior to the prostate volume in the assessment of maximum flow rate and thus the follow up of patients with benign prostatic hypertrophy. This measure which is non-invasive, easy to measure, easily accessible, and cost effective may be a useful tool in predicting voiding dysfunction and acute urinary retention.展开更多
