Kidney stone disease (KSD) is a worldwide disease leading to more than one million emergency department visits each
year. The current study aimed to assess risk factors for formulation of kidney stone among adult males, through a casecontrol
study which was conducted at outpatient clinics of nephrology, urology and general medicine in Nephrology and
Urology, Mit-Ghamer Hospital, affiliated to Ministry of Health and Population on a convenience sample of 158 case,
and 158 control. The researcher developed a structured interview to assess on socio-demographic characteristics, health
status, and life style of case and control groups. Results illustrated that, case group had significant higher number of
relatives with KSD (63.3%, n=100) than those in control group (17.1%, n= 27) with 2 = 70.15, P= 0.000, urinary tract
infection, recurrent pelvic, and renal inflammations, and insertion of urinary catheter, were higher in case group then in
control group (X2=55.71, 81.99, 78.50, and 47.16, respectively and p =0.00), as well 74.1% (117) of case group was
obese, compared to only 44.3%(70) of control group. We can conclude that: health status factors as well, life style
factors can contribute to be risk factors of kidney stones formulation in adult males including; dietary habits and
inadequate water drinking. Finally the researcher has recommended reusing awareness of public about risk factors of
kidney stones, and carrying out further researches on larger sample to investigate risk factors of kidney stones among
Egyptian's males.
