Lithotomy
Lithotomy from Greek for "lithos" (stone) and "tomos" (cut), is a surgical method for removal of calculi, stones formed inside certain organs, such as the urinary tract (kidney stones), bladder (bladder stones), and gallbladder (gallstones), that cannot exit naturally through the urinary system or biliary tract. The procedure is usually performed by means of a surgical incision (therefore invasive). Lithotomy differs from lithotripsy, where the stones are crushed either by a minimally invasive probe inserted through the exit canal, or by an acoustic pulse (extracorporeal shock wave lithotripsy), which is a non-invasive procedure. Because of these less invasive procedures, the use of lithotomy has decreased significantly in the modern era.

Kidney Stone
Kidney stone disease, also known as nephrolithiasis or urolithiasis, is a crystallopathy where a solid piece of material (kidney stone) develops in the urinary tract. Kidney stones typically form in the kidney and leave the body in the urine stream. A small stone may pass without causing symptoms. If a stone grows to more than , it can cause blockage of the ureter, resulting in sharp and severe pain in the lower back or abdomen. A stone may also result in blood in the urine, vomiting, or painful urination. About half of people who have had a kidney stone will have another within ten years. Most stones form by a combination of genetics and environmental factors. Risk factors include high urine calcium levels, obesity, certain foods, some medications, calcium supplements, hyperparathyroidism, gout and not drinking enough fluids. Stones form in the kidney when minerals in urine are at high concentration. The diagnosis is usually based on symptoms, urine testing, and medical i ...

Calculus (medicine)
A calculus (plural calculi), often called a stone, is a concretion of material, usually mineral salts, that forms in an organ or duct of the body. Formation of calculi is known as lithiasis (). Stones can cause a number of medical conditions. Some common principles (below) apply to stones at any location, but for specifics see the particular stone type in question. Calculi are not to be confused with gastroliths. Types * Calculi in the urinary system are called urinary calculi and include kidney stones (also called renal calculi or nephroliths) and bladder stones (also called vesical calculi or cystoliths). They can have any of several compositions, including mixed. Principal compositions include oxalate and urate. * Calculi of the gallbladder and bile ducts are called gallstones and are primarily developed from bile salts and cholesterol derivatives. * Calculi in the nasal passages (rhinoliths) are rare. * Calculi in the gastrointestinal tract ( enteroliths) can be enormous.

Common Era
Common Era (CE) and Before the Common Era (BCE) are year notations for the Gregorian calendar (and its predecessor, the Julian calendar), the world's most widely used calendar era. Common Era and Before the Common Era are alternatives to the original Anno Domini (AD) and Before Christ (BC) notations used for the same calendar era. The two notation systems are numerically equivalent: " CE" and "AD " each describe the current year; "400 BCE" and "400 BC" are the same year. The expression traces back to 1615, when it first appeared in a book by Johannes Kepler as the la, annus aerae nostrae vulgaris (), and to 1635 in English as " Vulgar Era". The term "Common Era" can be found in English as early as 1708, and became more widely used in the mid-19th century by Jewish religious scholars. Since the later 20th century, BCE and CE have become popular in academic and scientific publications because BCE and CE are religiously neutral terms. They are used by others who wish to be sensit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Paulus Aegineta
Paul of Aegina or Paulus Aegineta ( el, Παῦλος Αἰγινήτης; Aegina, ) was a 7th-century Byzantine Greek physician best known for writing the medical encyclopedia ''Medical Compendium in Seven Books.'' He is considered the “Father of Early Medical Writing”. For many years in the Byzantine Empire, his works contained the sum of all Western medical knowledge and was unrivaled in its accuracy and completeness. Life Nothing is known about his life, except that he was born in the island of Aegina, and that he travelled a good deal, visiting, among other places, Alexandria. He is sometimes called ''Iatrosophistes'' and ''Periodeutes'', a word which probably means a physician who travelled from place to place in the exercise of his profession. The exact time when he lived is not known; but, as he quotes Alexander of Tralles, and is himself quoted by Yahya ibn Sarafyun (''Serapion the Elder''), it is probable that Abu-al-Faraj is correct in placing him in the latter half ...

Susruta
The ''Sushruta Samhita'' (सुश्रुतसंहिता, IAST: ''Suśrutasaṃhitā'', literally "Suśruta's Compendium") is an ancient Sanskrit text on medicine and surgery, and one of the most important such treatises on this subject to survive from the ancient world. The ''Compendium of Suśruta'' is one of the foundational texts of Ayurveda (Indian traditional medicine), alongside the '' Charaka-Saṃhitā'', ''the Bheḷa-Saṃhitā'', and the medical portions of the Bower Manuscript. It is one of the two foundational Hindu texts on the medical profession that have survived from ancient India. The ''Suśrutasaṃhitā'' is of great historical importance because it includes historically unique chapters describing surgical training, instruments and procedures which is still followed by modern science of surgery. One of the oldest ''Sushruta Samhita'' palm-leaf manuscripts is preserved at the Kaiser Library, Nepal. History Date Over a century ago, the scholar ...

Aulus Cornelius Celsus
Aulus Cornelius Celsus ( 25 BC 50 AD) was a Roman encyclopaedist, known for his extant medical work, ''De Medicina'', which is believed to be the only surviving section of a much larger encyclopedia. The ''De Medicina'' is a primary source on diet, pharmacy, surgery and related fields, and it is one of the best sources concerning medical knowledge in the Roman world. The lost portions of his encyclopedia likely included volumes on agriculture, law, rhetoric, and military arts. He made contributions to the classification of human skin disorders in dermatology, such as myrmecia, and his name is often found in medical terminology regarding the skin, e.g., kerion celsi and area celsi. Life Nothing is known about the life of Celsus. Even his praenomen is uncertain; he has been called both Aurelius and Aulus, with the latter being more plausible. Some incidental expressions in his ''De Medicina'' suggest that he lived under the reigns of Augustus and Tiberius; which is confirmed by ...

Alexandria
Alexandria ( or ; ar, ٱلْإِسْكَنْدَرِيَّةُ ; grc-gre, Αλεξάνδρεια, Alexándria) is the second largest city in Egypt, and the largest city on the Mediterranean coast. Founded in by Alexander the Great, Alexandria grew rapidly and became a major centre of Hellenic civilisation, eventually replacing Memphis, in present-day Greater Cairo, as Egypt's capital. During the Hellenistic period, it was home to the Lighthouse of Alexandria, which ranked among the Seven Wonders of the Ancient World, as well as the storied Library of Alexandria. Today, the library is reincarnated in the disc-shaped, ultramodern Bibliotheca Alexandrina. Its 15th-century seafront Qaitbay Citadel is now a museum. Called the "Bride of the Mediterranean" by locals, Alexandria is a popular tourist destination and an important industrial centre due to its natural gas and oil pipelines from Suez. The city extends about along the northern coast of Egypt, and is the largest city on t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ammonius Lithotomos
Ammonius Lithotomos (; el, Ἀμμώνιος; fl. 3rd century BC), of Alexandria, was a Greek lithotomist. Work Reported by Celsus, Ammonius invented the tools to break up " bladder stones". :"A hook or crotchet is fixed upon the stone in such a way as easily to hold it firm, even when shaken, so that it may not revolve backward; then an iron instrument is used, of moderate thickness, thin at the front end but blunt, which, when applied to the stone and struck at the other end, cleaves it. Great care must be taken that the instrument do not come into contact with the bladder itself, and that nothing fall upon it by the breaking of the stone." This is the method Ammonius uses to break up stones in the bladder as reported by Celsus Lithoclastic cystotomy is attributed to Ammonius ''Lithotomos'' (stone-cutter), from which arose the term lithotomy, now having the arbitrary signification of cutting for the stone. Celsus gave the first description of lithotomy as performed before and du ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Perineum
The perineum in humans is the space between the anus and scrotum in the male, or between the anus and the vulva in the female. The perineum is the region of the body between the pubic symphysis (pubic arch) and the coccyx (tail bone), including the perineal body and surrounding structures. There is some variability in how the boundaries are defined. The perineal raphe is visible and pronounced to varying degrees. The perineum is an erogenous zone. The word perineum entered English from late Latin via Greek περίναιος ~ περίνεος ''perinaios, perineos'', itself from περίνεος, περίνεοι 'male genitals' and earlier περίς ''perís'' 'penis' through influence from πηρίς ''pērís'' 'scrotum'. The term was originally understood as a purely male body-part with the perineal raphe seen as a continuation of the scrotal septum since masculinization causes the development of a large anogenital distance in men, in comparison to the corresponding lack ...

Physician
A physician (American English), medical practitioner (Commonwealth English), medical doctor, or simply doctor, is a health professional who practices medicine, which is concerned with promoting, maintaining or restoring health through the study, diagnosis, prognosis and treatment of disease, injury, and other physical and mental impairments. Physicians may focus their practice on certain disease categories, types of patients, and methods of treatment—known as specialities—or they may assume responsibility for the provision of continuing and comprehensive medical care to individuals, families, and communities—known as general practice. Medical practice properly requires both a detailed knowledge of the academic disciplines, such as anatomy and physiology, underlying diseases and their treatment—the ''science'' of medicine—and also a decent competence in its applied practice—the art or ''craft'' of medicine. Both the role of the physician and the meaning ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Surgeon
In modern medicine, a surgeon is a medical professional who performs surgery. Although there are different traditions in different times and places, a modern surgeon usually is also a licensed physician or received the same medical training as physicians before specializing in surgery. There are also surgeons in podiatry, dentistry, and veterinary medicine. It is estimated that surgeons perform over 300 million surgical procedures globally each year. History The first person to document a surgery was the 6th century BC Indian physician-surgeon, Sushruta. He specialized in cosmetic plastic surgery and even documented an open rhinoplasty procedure.Ira D. Papel, John Frodel, ''Facial Plastic and Reconstructive Surgery'' His magnum opus ''Suśruta-saṃhitā'' is one of the most important surviving ancient treatises on medicine and is considered a foundational text of both Ayurveda and surgery.

Hippocratic Oath
The Hippocratic Oath is an oath of ethics historically taken by physicians. It is one of the most widely known of Greek medical texts. In its original form, it requires a new physician to swear, by a number of healing gods, to uphold specific ethical standards. The oath is the earliest expression of medical ethics in the Western world, establishing several principles of medical ethics which remain of paramount significance today. These include the principles of medical confidentiality and non-maleficence. As the seminal articulation of certain principles that continue to guide and inform medical practice, the ancient text is of more than historic and symbolic value. It is enshrined in the legal statutes of various jurisdictions, such that violations of the oath may carry criminal or other liability beyond the oath's symbolic nature. The original oath was written in Ionic Greek, between the fifth and third centuries BC. Although it is traditionally attributed to the Greek doc ...
