Cholelithiasis in the Kenyan African.

A prospective and retrospective review of 20 cases of cholelithiasis diagnosed at Kenyatta National Hospital (KNH) between June 1987 and June 1989 was done. Females were more often affected (6 times) than their male counterparts. 94% of the females were parous with a mean parity of 5.6. Most patients were in the 4th decade at the time of diagnosis. Qualitative analysis for gall-stones showed evidence of cholesterol in all stones analysed with calcium being detected in only one female patient.
