Leopold Ritter Von Dittel
Leopold Ritter von Dittel (May 29, 1815 – July 28, 1898) was an Austrian urologist born in Fulnek, a community now located in the Czech Republic. Dittel received his medical doctorate in 1840 from the University of Vienna, and as a young man worked as a physician in Trenčianske Teplice, Trentschin-Teplitz. From 1853 to 1857, he was an assistant to Johann von Dumreicher (1815-1880) and a surgical assistant at the university hospital in Vienna. Later, he became surgeon-in-chief of the ''Allgemeines Krankenhaus'', and in 1865 attained the title of associate professor. He is credited for developing a number of innovative diagnostic and surgical practices in the field of genitourinary medicine. He is remembered for his pioneer diagnostic work with the cystoscope, a device that was a recent invention of urologist Maximilian Nitze (1848–1906). In urology, the cystoscope is used for endoscope, endoscopic detection of urinary bladder, bladder tumors and other urinary disorders. With F ...

Urethra
The urethra (from Greek οὐρήθρα – ''ourḗthrā'') is a tube that connects the urinary bladder to the urinary meatus for the removal of urine from the body of both females and males. In human females and other primates, the urethra connects to the urinary meatus above the vagina, whereas in marsupials, the female's urethra empties into the urogenital sinus. Females use their urethra only for urinating, but males use their urethra for both urination and ejaculation. The external urethral sphincter is a striated muscle that allows voluntary control over urination. The internal sphincter, formed by the involuntary smooth muscles lining the bladder neck and urethra, receives its nerve supply by the sympathetic division of the autonomic nervous system. The internal sphincter is present both in males and females. Structure The urethra is a fibrous and muscular tube which connects the urinary bladder to the external urethral meatus. Its length differs between the se ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Jewish Encyclopedia
''The Jewish Encyclopedia: A Descriptive Record of the History, Religion, Literature, and Customs of the Jewish People from the Earliest Times to the Present Day'' is an English-language encyclopedia containing over 15,000 articles on the history, culture, and state of Judaism up to the early 20th century. The encyclopedia's managing editor was Isidore Singer and the editorial board was chaired by Isaac K. Funk and Frank H. Vizetelly. The work's scholarship is still highly regarded. The American Jewish Archives deemed it "the most monumental Jewish scientific work of modern times", and Rabbi Joshua L. Segal said "for events prior to 1900, it is considered to offer a level of scholarship superior to either of the more recent Jewish encyclopedias written in English." It was originally published in 12 volumes between 1901 and 1906 by Funk & Wagnalls of New York, and reprinted in the 1960s by KTAV Publishing House. It is now in the public domain. History Conce ...

Kidney Calculus
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 im ...

Bladder Stone
A bladder stone is a stone found in the urinary bladder. Signs and symptoms Bladder stones are small mineral deposits that can form in the bladder. In most cases bladder stones develop when the urine becomes very concentrated or when one is dehydrated. This allows for minerals, such as calcium or magnesium salts, to crystallize and form stones. Bladder stones vary in number, size and consistency. In some cases bladder stones do not cause any symptoms and are discovered as an incidental finding on a plain radiograph. However, when symptoms do occur, these may include severe lower abdominal and back pain, difficult urination, frequent urination at night, fever, painful urination and blood in the urine. The majority of individuals who are symptomatic will complain of pain which comes in waves. The pain may also be associated with nausea, vomiting and chills.

Theodor Billroth
Christian Albert Theodor Billroth (26 April 18296 February 1894) was a German surgeon and amateur musician. As a surgeon, he is generally regarded as the founding father of modern abdominal surgery. As a musician, he was a close friend and confidant of Johannes Brahms, a leading patron of the Viennese musical scene, and one of the first to attempt a scientific analysis of musicality. Early life and education Billroth was born at Bergen auf Rügen in the Kingdom of Prussia, the son of a pastor. His father died of tuberculosis when Billroth was five years old. He attended school in Greifswald where he obtained his ''Abitur'' degree in 1848. Billroth was an indifferent student, and spent more time practicing piano than studying. Torn between a career as a musician or as a physician, he acceded to his mother's wishes and enrolled himself at the University of Greifswald to study medicine, but gave up the whole of his first term to the study of music; Professor Wilhelm Baum, however, ...

Franz Von Pitha
Franz Freiherr von Pitha (born ''Jiří František Piťha'', 8 February 1810 – 29 December 1875) was an Austrian surgeon. He was rector of the Charles University in Prague in 1854–1855. Biography Pitha was born in Řakom near Klatovy (today part of Dolany in the Czech Republic). In 1836 he received his medical doctorate at Prague, and was later a professor of surgery at Charles University in Prague, and at Josephs Academy (Josephinum) in Vienna, where he was chair of surgery from 1857 to 1874. During the Italian Wars of Independence, Pitha was chief of field medical services. In this role he made advancements in Austrian military hygiene, and also gained experience regarding battle-related injuries. He published a treatise titled ''Verletzungen und Krankheiten der Extremitäten'' (Injuries and Diseases of the Extremities), as a result of his war-time experiences. Pitha was instrumental in acquiring a position for Theodor Billroth (1829–1894) at the medical faculty in Vie ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Prostate
The prostate is both an accessory gland of the male reproductive system and a muscle-driven mechanical switch between urination and ejaculation. It is found only in some mammals. It differs between species anatomically, chemically, and physiologically. Anatomically, the prostate is found below the bladder, with the urethra passing through it. It is described in gross anatomy as consisting of lobes and in microanatomy by zone. It is surrounded by an elastic, fibromuscular capsule and contains glandular tissue as well as connective tissue. The prostate glands produce and contain fluid that forms part of semen, the substance emitted during ejaculation as part of the male sexual response. This prostatic fluid is slightly alkaline, milky or white in appearance. The alkalinity of semen helps neutralize the acidity of the vaginal tract, prolonging the lifespan of sperm. The prostatic fluid is expelled in the first part of ejaculate, together with most of the sperm, because of th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dislocation Of Hip
A hip dislocation is when the thighbone (femur) separates from the hip bone (pelvis). Specifically it is when the ball–shaped head of the femur (femoral head) separates from its cup–shaped socket in the hip bone, known as the acetabulum. The joint of the femur and pelvis (hip joint) is very stable, secured by both bony and soft-tissue constraints. With that, dislocation would require significant force which typically results from significant trauma such as from a motor vehicle collision or from a fall from elevation. Hip dislocations can also occur following a hip replacement or from a developmental abnormality known as hip dysplasia. Hip dislocations are classified by fracture association and by the positioning of the dislocated femoral head. A posteriorly positioned head is the most common dislocation type. Hip dislocations are a medical emergency, requiring prompt placement of the femoral head back into the acetabulum ( reduction). This reduction of the femoral head back ...

Human Male Genitalia
The male reproductive system consists of a number of sex organs that play a role in the process of human reproduction. These organs are located on the outside of the body and within the pelvis. The main male sex organs are the penis and the testicles which produce semen and sperm, which, as part of sexual intercourse, fertilize an ovum in the female's body; the fertilized ovum (zygote) develops into a fetus, which is later born as an infant. The corresponding system in females is the female reproductive system. External genital organs Penis The penis is the male intromittent organ. It has a long shaft and an enlarged bulbous-shaped tip called the glans penis, which supports and is protected by the foreskin. When the male becomes sexually aroused, the penis becomes erect and ready for sexual activity. Erection occurs because sinuses within the erectile tissue of the penis become filled with blood. The arteries of the penis are dilated while the veins are compressed so that ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
