In medicine, a sound (/ s aʊ n d /), also called a sonde (/ s ɒ n d /), [help 1] is an instrument for probing and dilating passages within the body, the best-known examples of which are urethral sounds and uterine sounds.
Examples of sinusoidally amplitude- and frequency-modulated signals. The neural representation of stimulus envelope, ENV n, has typically been studied using well-controlled ENV p modulations, that is sinusoidally amplitude-modulated (AM) sounds. Cochlear filtering limits the range of AM rates encoded in individual auditory-nerve fibers. In the ...
Urethral sounding is the practice of inserting objects (typically made by metal or silicone) into the urethra for sexual gratification. [1] Urethral dilatation is a urological procedure that uses probes called sounds to enlarge the inside diameter of the urethra and locate obstructions in the urethra, or as a treatment for urethral strictures.
Trills involve the vibration of one of the speech organs. Since trilling is a separate parameter from stricture, the two may be combined. Increasing the stricture of a typical trill results in a trilled fricative. Trilled affricates are also known. Nasal airflow may be added as an independent parameter to any speech sound.
It is also sometimes called a stricture (as in urethral stricture). [ 3 ] Stricture as a term is usually used when narrowing is caused by contraction of smooth muscle (e.g. achalasia , prinzmetal angina ); stenosis is usually used when narrowing is caused by lesion that reduces the space of lumen (e.g. atherosclerosis ). [ 4 ]
Obstruction in the urethra, for example a stricture (usually caused either by injury or STD), a metastasis or a precipitated pseudogout crystal in the urine; Pseudodyssynergia; STD lesions (gonorrhoea causes numerous strictures, leading to a "rosary bead" appearance, whereas chlamydia usually causes a single stricture) Emasculation
A urethral stricture is a narrowing of the urethra, the tube connected to the bladder that allows urination. The narrowing reduces the flow of urine and makes it more difficult or even painful to empty the bladder. [1] Urethral stricture is caused by injury, instrumentation, infection, and certain non-infectious forms of urethritis. The ...
Laryngotracheal stenosis is an umbrella term for a wide and heterogeneous group of very rare conditions. The population incidence of adult post-intubation laryngotracheal stenosis which is the commonest benign sub-type of this condition is approximately 1 in 200,000 adults per year. [10] The main causes of adult laryngotracheal stenosis are:
