El proceso de producción de «Étude sur le Rein des Urinaires», tesis doctoral de Joaquin Albarrán en la Facultad de Medicina de París

Joaquín Albarrán described and beautifully illustrated himself the role «pyogenic bacillus» (E. coli) played in renal infection, bacteriemia, renal failure sepsis and patient death. The evolution of pyelonephritis to perinephritis and perinephric abscess was masterly interpreted, with new description of ascending infection and lymphatic peritubular dissemination of bacteria. The differences detected between written and printed work are numerous and can be explained by the corrections of Prof. Guyon before definite presentation and the technical process to perform the lithographs.
