Background: Intravesical prostatic protrusion (IPP) is a noninvasive test that can predict bladder outlet obstruction in patients with benign prostatic hyperplasia (BPH). Objective: The objective of this study was to determinethe correlation between IPP and International Prostate Symptom Score (IPSS) in patients with BPH. Patients and Methods: A cross-sectional prospective study of new patients with symptomatic BPH who presented to the urology clinics of NAUTH, Nnewi. Ethical approval and informed consent were obtained. Participants had abdominal ultrasonography measurements of IPP from midline sagittal image of the prostate (at bladder volume ≥100 mL) using Prosound SSD3500 with abdominal probe frequency of 3.5 MHz. IPP was divided into three grades (grade I: 0–4.9mm, grade II: 5.0–9.9 mm, and grade III: ≥10.0 mm). Data were analyzed using SPSS version 20. The data were subjected to analysis of variance, and Pearson's correlation was used to assess correlation where necessary. P value < 0.05 was considered significant. Results: In all, 101 men with a mean age of 67.09 ± 10.93 years were included in the study. The average IPSS, storage symptoms IPSS (IPSS-S), voiding symptoms IPSS (IPSS-V), Quality of Life (QoL) index, and IPP were 17.05 ± 7.62, 7.81 ± 5.17, 9.24 ± 3.16, 4.75 ± 1.59, and 13.50 ± 7.47 mm, respectively. There were significant differences between the mean IPSS (P = 0.000), mean IPSS-S (P = 0.000), and mean IPSS-V (P = 0.002) among the three grades of IPP. There were significant positive correlations between IPP and IPSS (P = 0.000), IPSS-S (P = 0.000), IPSS-V (P = 0.000), and IPSS QoL index (P = 0.000). Conclusion: There were significant positive correlations between IPP and IPSS, IPSS-S, IPSS-V, and IPSS QoL index.
