Abstract
BACKGROUND: Benign prostatic hyperplasia (BPH) is a prevalent condition among aging males, leading to progressive lower urinary tract symptoms (LUTS) due to prostate enlargement and bladder dysfunction. This study aimed to assess the correlation between prostate volume (PV) and key ultrasonographic parameters, including intravesical prostatic protrusion (IPP), bladder wall thickness (BWT), and post-void residual urine (PVRU), to evaluate their clinical significance in BPH management. METHODS: A cross-sectional study was conducted on 105 male patients diagnosed with BPH. Prostate volume, IPP, BWT, and PVRU were measured using transabdominal ultrasonography. Pearson's correlation analysis and chi-square tests were used to assess the associations between these parameters. Statistical significance was set at p < 0.05. RESULTS: Strong positive correlation were observed between PV and IPP (r = 0.789, p < 0.001), PV and BWT (r = 0.65, p < 0.001), and PV and PVRU (r = 0.805, p < 0.001). The highest correlation was found between IPP and PVRU (r = 0.851, p < 0.001), suggesting that increased IPP is a strong predictor of urinary retention. Patients with larger prostates ( > 60 cc) exhibited significantly higher grades of IPP, BWT, and PVRU (p < 0.001), indicating a progressive decline in bladder function as prostate volume increases. CONCLUSION: This study confirms that IPP, BWT, and PVRU are strongly associated with prostate volume, with IPP emerging as a key predictor of urinary retention severity in patients with BPH. These findings underscore the importance of integrating ultrasonographic assessments, particularly IPP and BWT measurements, into routine clinical evaluations to improve the early detection and management of BPH. Future multicenter, longitudinal studies are recommended to validate these findings and optimize clinical decision-making.
