Abstract:

Background
The aim of the study is to find the correlation between the prostate volume and severity of lower urinary tract symptoms (LUTS) as measured by international prostate symptoms score and maximum urine flow rate among patients with benign prostatic hyperplasia (BPH).

Methods
The study was a prospective correlational study conducted between June 2016 and November 2017. A total of 290 patients who presented with LUTS suggestive of BPH and satisfied the inclusion criteria were consecutively recruited. Clinical evaluation including digital rectal examination of the prostate was done. Symptoms severity was assessed using the self-administered international prostate symptoms score (IPSS) questionnaire. Prostate volume was determined by transrectal ultrasound scan, and the urine flow rate was measured using uroflowmeter. Data were analyzed using SPSS version 20.0, and p value < 0.05 was taken to be statistically significant.

Results
The mean age of the patients was 64.22 ± 9.04 years with a range of 40 to 95 years. Most of the patients had moderate symptoms (55%) on IPSS with the mean IPSS value of 16.41 ± 7.43. The mean Qmax value was 16.55 ± 7.41 ml/s, and the median prostate volume (IQR) was 45.05 (35, 59). There was a positive significant correlation between prostate volume and IPSS (r = 0.179, p = 0.002) and a negative significant correlation between prostate volume and Qmax (r = − 0.176, p = 0.003).

Conclusion
This study showed a significant correlation between the prostate volume and IPSS, and also between prostate volume and maximum flow rate (Qmax).
