The surgical technique known as sectio mariana marked a distinct advancement in sixteenth-century medical practice. Developed by Mariano Santo, this procedure utilized a specialized instrument called the esploratorium to facilitate the extraction of renal calculi. Santo’s career spanned decades of clinical study, military service, and academic instruction across various European cities throughout the Renaissance era.
Early Education and Career
Born in 1488 in Barletta, Italy, Santo relocated to Rome in 1510 to begin his formal study of medicine. His professional path led him to an academic position at Bologna University, where he instructed students in surgical methods. This early period established his reputation as a scholar of medicine before he transitioned into more specialized clinical roles.

In 1520, Santo returned to Barletta following his father's death. He married Maddalena Braccio in 1524, and the couple eventually had four sons. Their residence shifted frequently during this decade, including a move to Milan in 1526 and a relocation to Ragusa, now known as Dubrovnik, in 1527. During the conflict between Austria and the Ottomans, he provided surgical care on active battlefields, eventually settling in Venice.
Contributions to Surgical Literature
Santo produced significant medical texts during his career, writing in Latin. His primary works include Artium et medicine, De lapide renum, and Libellus Aureus de lapide a vesica per incisionem extrahendo. These publications codified his observations and techniques, specifically regarding the treatment of urinary tract conditions. These works were distributed in centers such as Paris, ensuring the circulation of his surgical theories among contemporary practitioners.
Final Years and Legacy
The latter portion of his life concluded in Rome, where he passed away in 1577 at the age of 89. His remains were interred at the church of Santa Maria sopra Minerva. His career remains a subject of study in the history of urology due to his early introduction of formal tools and specific incisions designed to treat bladder and kidney stones.
