[Professor Joachim Albarran. Urologist and scientist ahead of his time]

The article analyzes the scientific and practical activities of the prominent French urologist Professor Joachim Albarran (1860-1912). It is noted that a student of the founder of French urology F. Guyon I. Albarran in 1906 was elected in his place Professor of urology and head of the Department of the Necker hospital (Hopital Necker) in Paris. It is shown that in 1891 he published a work on bladder tumors, creating a new progressive classification of them. This paper presents well-known monographs by I. Albarran on the mechanism of origin of hydronephrosis, tuberculosis, and kidney tumors. He developed a method for studying the functional activity of the kidneys and proposed the method of "experimental polyuria" (1905). It is also noted that I. Albarran invented the catheterization cystoscope and this made ureteral catheterization a method widely available in practical surgery. I. Albarrans extensive operational experience was described in his manual of operative surgery of the urinary tract (1909), which still has not lost its value. I. Albarran created a brilliant scientific school, from which came a whole galaxy of outstanding clinicians and urologists.
