Objectives: Determine the association  between LUTS associated with BPH and metabolic syndrome.
Methods: The study was conducted over 100 patient at Sohag university hospital.
Results: Regarding the relation between BMI and LUTS we found that the mean of BPH volume&prostatic specific antigen  was significantly higher in obese patients than normal and overweight patients.
Regarding  the relation between diabetes mellitus and LUTS we found that the mean flowrate was lower in diabetic patients than non diabetic patients.
Regarding the  relation between hypertension and LUTS we found that mean IPSS and PSA was higher in hypertensive patient than non hypertensive patients.
Conclusion: BPH volume was significantly correlated with each of age,
 body mass index,waste circumference, triglyceride and cholestrol.
IPSS was significantly correlated with body mass indx and diabetus mellitus.
