title: Isaac Judaeus Israeli: a Jewish founder of the origins of nephrology.
abstract: This paper discusses the Book of Urine in the Opera Omnia Isaci of Isaac Judaeus Israeli. Born in Egypt in the middle of the ninth century, Isaac Judaeus was considered a genius by his peers. The book accepted Galen's ideas and expanded them. Its original contribution was in the concept of the seeping of fluid and sediment from blood into the kidney and from the kidney to the bladder. This concept corresponds to glomerular filtration and tubular secretion.
