A tube that transports URINE from the URINARY BLADDER to the outside of the body in both the sexes. It also has a reproductive function in the male by providing a passage for SPERM.
Pathological processes involving the URETHRA.
Cancer or tumors of the URETHRA. Benign epithelial tumors of the urethra usually consist of squamous and transitional cells. Primary urethral carcinomas are rare and typically of squamous cells. Urethral carcinoma is the only urological malignancy that is more common in females than in males.
Narrowing of any part of the URETHRA. It is characterized by decreased urinary stream and often other obstructive voiding symptoms.
A musculomembranous sac along the URINARY TRACT. URINE flows from the KIDNEYS into the bladder via the ureters (URETER), and is held there until URINATION.
Partial or complete blockage in any part of the URETHRA that can lead to difficulty or inability to empty the URINARY BLADDER. It is characterized by an enlarged, often damaged, bladder with frequent urges to void.
The external reproductive organ of males. It is composed of a mass of erectile tissue enclosed in three cylindrical fibrous compartments. Two of the three compartments, the corpus cavernosa, are placed side-by-side along the upper part of the organ. The third compartment below, the corpus spongiosum, houses the urethra.
The body region lying between the genital area and the ANUS on the surface of the trunk, and to the shallow compartment lying deep to this area that is inferior to the PELVIC DIAPHRAGM. The surface area is between the VULVA and the anus in the female, and between the SCROTUM and the anus in the male.
Involuntary discharge of URINE as a result of physical activities that increase abdominal pressure on the URINARY BLADDER without detrusor contraction or overdistended bladder. The subtypes are classified by the degree of leakage, descent and opening of the bladder neck and URETHRA without bladder contraction, and sphincter deficiency.
Inflammation involving the URETHRA. Similar to CYSTITIS, clinical symptoms range from vague discomfort to painful urination (DYSURIA), urethral discharge, or both.
Surgical creation of an opening (stoma) in the URINARY BLADDER for drainage.
Passage of a CATHETER into the URINARY BLADDER or kidney.
Discharge of URINE, liquid waste processed by the KIDNEY, from the body.
The mechanical laws of fluid dynamics as they apply to urine transport.
The duct which coveys URINE from the pelvis of the KIDNEY through the URETERS, BLADDER, and URETHRA.
All the organs involved in reproduction and the formation and release of URINE. It includes the kidneys, ureters, BLADDER; URETHRA, and the organs of reproduction - ovaries, UTERUS; FALLOPIAN TUBES; VAGINA; and CLITORIS in women and the testes; SEMINAL VESICLES; PROSTATE; seminal ducts; and PENIS in men.
Endoscopic examination, therapy or surgery of the urinary bladder.
Unstriated and unstriped muscle, one of the muscles of the internal organs, blood vessels, hair follicles, etc. Contractile elements are elongated, usually spindle-shaped cells with centrally located nuclei. Smooth muscle fibers are bound together into sheets or bundles by reticular fibers and frequently elastic nets are also abundant. (From Stedman, 25th ed)
Properties, functions, and processes of the URINARY TRACT as a whole or of any of its parts.
An abnormal passage in any part of the URINARY TRACT between itself or with other organs.
Glands situated on each side of the prostate that secrete a fluid component of the seminal fluid into the urethra.
Surgery performed on the urinary tract or its parts in the male or female. For surgery of the male genitalia, UROLOGIC SURGICAL PROCEDURES, MALE is available.
Pathological processes of the URINARY BLADDER.
An erectile structure homologous with the penis, situated beneath the anterior labial commissure, partially hidden between the anterior ends of the labia minora.
Soft tissue formed mainly by the pelvic diaphragm, which is composed of the two levator ani and two coccygeus muscles. The pelvic diaphragm lies just below the pelvic aperture (outlet) and separates the pelvic cavity from the PERINEUM. It extends between the PUBIC BONE anteriorly and the COCCYX posteriorly.
Dysfunction of the URINARY BLADDER due to disease of the central or peripheral nervous system pathways involved in the control of URINATION. This is often associated with SPINAL CORD DISEASES, but may also be caused by BRAIN DISEASES or PERIPHERAL NERVE DISEASES.
The genital canal in the female, extending from the UTERUS to the VULVA. (Stedman, 25th ed)
The space or compartment surrounded by the pelvic girdle (bony pelvis). It is subdivided into the greater pelvis and LESSER PELVIS. The pelvic girdle is formed by the PELVIC BONES and SACRUM.
Involuntary loss of URINE, such as leaking of urine. It is a symptom of various underlying pathological processes. Major types of incontinence include URINARY URGE INCONTINENCE and URINARY STRESS INCONTINENCE.
Stones in the URINARY BLADDER; also known as vesical calculi, bladder stones, or cystoliths.
A slightly movable cartilaginous joint which occurs between the pubic bones.
Works containing information articles on subjects in every field of knowledge, usually arranged in alphabetical order, or a similar work limited to a special field or subject. (From The ALA Glossary of Library and Information Science, 1983)
A nerve which originates in the sacral spinal cord (S2 to S4) and innervates the PERINEUM, the external GENITALIA, the external ANAL SPHINCTER and the external urethral sphincter. It has three major branches: the perineal nerve, inferior anal nerves, and the dorsal nerve of penis or clitoris.
Paired ducts in the human male through which semen is ejaculated into the urethra.
Blood in the SEMEN, usually due to INFLAMMATION of the PROSTATE, the SEMINAL VESICLES, or both.
An idiopathic, segmental, nonatheromatous disease of the musculature of arterial walls, leading to STENOSIS of small and medium-sized arteries. There is true proliferation of SMOOTH MUSCLE CELLS and fibrous tissue. Fibromuscular dysplasia lesions are smooth stenosis and occur most often in the renal and carotid arteries. They may also occur in other peripheral arteries of the extremity.
Part of the back and base of the CRANIUM that encloses the FORAMEN MAGNUM.
Legal documents that are declarations of individuals' wishes regarding the disposal of their property or estate after death; esp: written instruments, legally executed, by which dispositions are made of estates. LIVING WILLS are written declarations regarding prolongation of life by extraordinary means.
Individuals responsible for various duties pertaining to the medical office routine.
Stress wherein emotional factors predominate.
A surgical specialty concerned with the study, diagnosis, and treatment of diseases of the urinary tract in both sexes, and the genital tract in the male. Common urological problems include urinary obstruction, URINARY INCONTINENCE, infections, and UROGENITAL NEOPLASMS.
Any substances taken in by the body that provide nourishment.
Drugs that act locally on cutaneous or mucosal surfaces to produce inflammation; those that cause redness due to hyperemia are rubefacients; those that raise blisters are vesicants and those that penetrate sebaceous glands and cause abscesses are pustulants; tear gases and mustard gases are also irritants.
