This category includes diseases of the urinary system and the male and female reproductive organs. Conditions range from congenital anomalies (e.g., hydronephrosis) to chronic diseases (e.g., chronic kidney disease) and infections (e.g., urinary tract infections). Phenotype logic may include diagnosis and procedure codes, lab results (e.g., creatinine, urinalysis), imaging studies, dialysis or transplant history, and medication usage. Example phenotypes might include “Nephrotic Syndrome,” defined by proteinuria, hypoalbuminemia, and edema, or “Recurrent UTI,” based on frequency of infections, culture data, and antibiotic use.
