The prevalence and clinical profile of patients diagnosed with renal calculi at the American Mission Hospital in the Kingdom of Bahrain

Abstract EN

Background : The prevalence of renal stone disease is increasing, with 5 % of women and 12 % of men in the US developing a kidney stone during their life.

Assessment of prevalence can help provide an improved understanding of risk factors and the impact of the disease at community level in Bahrain.

Objective : This study aimed to determine the prevalence of renal calculi and the clinical profile of patients presenting with renal colic at the American Mission Hospital (AMH).

Method : Study design, a retrospective medical record review of all patients with renal colic who visited AMH Jan to Dec 2010.

Data extraction was carried out by one investigator and cross checked.

Results : In this study population the prevalence of renal colic was found to be 0.022 %, and of renal calculi 0.020 %.

A higher percentage (60.5 %) of females than males were diagnosed with renal calculi : and 63 % occurred in the 20-40 yr and 30 % in the higher, and 7 % in the lower (< 20yr), age groups.

Non-smokers (67.4 %) were more affected than smokers.

Most (72 %) patients had no history of alcohol intake ; compared to mild (7 %), moderate (19 %), and high intake (2 %).

More cases (72 %) of renal calculi were diagnosed in the winter season compared to 28 % in the summer season.

Conclusion : The majority of patients with renal colic were diagnosed with renal calculi which were more common in females and in the 20-40 yr age group.

There appeared to be no significant relationship between smoking and alcohol intake and prevalence of renal calculi.
