Abstract
Background: Incidence of symptomatic prostatic diseases increases with age. Nocturia disturbs sleep. We set out to determine the quality of sleep and severity of lower urinary tract symptoms (LUTS) and bother score in patients with benign prostatic hyperplasia (BPH) and carcinoma of the prostate (CAP).
 Methods: A cross-sectional study of new patients seen in the urology outpatient clinic with bladder outlet obstruction (BOO) from either BPH or CAP over a period of 18 months. Patients were interviewed using Pittsburgh Sleep Quality Index (PSQI) and International prostate symptoms score (IPSS) questionnaires. Data obtained were analyzed using SPSS version 23.
 Results:168 patients were interviewed. CAP patients were older than their BPH counterparts. About 45% of the patients had poor sleep quality. CAP patients (52.9%) were more of poor sleepers compared with BPH patients (40.0%). CAP patients (46.3%) had more severe IPSS than BPH patients (33.3%). Both CAP (70.6%) and BPH (76.0%) patients reported high bother score.
 Conclusion: CAP and BPH patients have high bother score, affirming need for early treatment. CAP patients had more severe lower urinary tract symptoms and poorer sleep quality than BPH patients.

Highlights
Prostatic diseases including carcinoma are major health problems encountered in middle aged and elderly males worldwide [1, 2]
This study set out to compare the quality of sleep, severity and bother score of lower urinary tract symptoms (LUTS) in patients with carcinoma of the prostate (CAP) and benign prostatic hyperplasia (BPH)
Consecutive consenting new patients with lower urinary tract symptoms and with diagnosis of bladder outlet obstruction (BOO) secondary to either BPH or CAP were recruited into the study after appropriate counselling
Summary
Prostatic diseases including carcinoma are major health problems encountered in middle aged and elderly males worldwide [1, 2]. The diseases are more common in men from the sixth decade of life and beyond as evidenced by their high prevalence of lower urinary tract symptoms (LUTS) [3,4,5]. A number of factors affect sleep quality among patients with lower urinary tract (LUT) obstruction. This study set out to compare the quality of sleep, severity and bother score of LUTS in patients with carcinoma of the prostate (CAP) and benign prostatic hyperplasia (BPH). We set out to determine the quality of sleep and severity of lower urinary tract symptoms (LUTS) and bother score in patients with benign prostatic hyperplasia (BPH) and carcinoma of the prostate (CAP). Patients were interviewed using Pittsburgh Sleep Quality Index (PSQI) and International prostate symptoms score (IPSS) questionnaires. CAP patients had more severe lower urinary tract symptoms and poorer sleep quality than BPH patients
