1. a simple outline, as of the side view of the head or face.
2. a graph representing quantitatively a set of characteristics determined by tests.
biophysical profile a numeric scoring system used to assess the well-being of the fetus in high-risk pregnancies, based on the nonstress test combined with sonographic evaluation of fetal breathing, fetal movements, fetal tone, amniotic fluid volume, and, sometimes, the echogenicity of the placenta.
PULSES profile a tool for early functional assessment, comprising assessment of physical condition, upper limb function, lower limb function, sensory components, excretory function, and emotional or mental status.
urethral pressure profile (UPP) a record of the resistance of the urethra to fluid flow, measured as variations in urethral pressure. A liquid or gas is pumped into the bladder with a catheter in place and the catheter is slowly withdrawn while measurements are taken of the pressure at various points in the urethra. It is usually done from the internal orifice to the external orifice in females and from the internal orifice to the sphincter urethrae muscle in males.
u·re·thral pres·sure pro·file
the continual recording of pressure through a hole in the side of a small catheter as it is pulled (at a constant rate, although either water or a gas is infused through the hole) from a point within the bladder, through the vesical neck, and down the entire urethra; a form of resistance measurement that gives a tracing indicative of the functional length of the urethra and the points of maximal urethral resistance.
urethral pressure profileUrology A dataset used to determine the functional length, resting pressure, and maximal pressure of the urethral sphincter mechanisms
pertaining to or emanating from urethra.
urethral agenesis, urethral atresia
failure of development of all or part of the urethra: characterized by complete urine retention. A rare cause of neonatal uremia.
causes a syndrome of acute urethral obstruction (below).
see urachal diverticulum.
due to trauma; occurs in bulls in which the urethra lies superficially near its end. A fistula may affect the discharge of semen from the normal meatus sufficiently to cause infertility.
a median groove along the ventral surface of the genital tubercle providing an eventual location for the penile urethra in the male.
a cause of urinary incontinence in female dogs and rarely cats.
striated muscle in the wall of the male pelvic urethra.
causes acute abdominal pain with grunting and straining to urinate, tail switching, distention of the bladder, dripping of blood-stained urine, protrusion of the penis. Eventually the bladder ruptures or the urethra perforates. Caused usually by calculus. See also urolithiasis.
occurs usually at the site of urethral obstruction by a calculus. Causes urinary infiltration of the ventral abdominal wall and terminal uremia. Called also waterbelly. Rarely the accumulation occurs retroperitoneally and is palpable rectally. See also hypospadias.
a solid cord of endodermal cells which arise from the floor of the urogenital sinus, contributing to the formation of the urethral groove.
occurs in male cats causing urethral obstruction; associated with feline urological syndrome. The plug is composed of proteinaceous material with cellular debris and struvite crystals.
urethral pressure profile
a study of the intraurethral pressure as a means of identifying the cause of urinary incontinence in dogs and cats.
urethral pressure profilometry
a measure of intraurethral pressures; used in the investigation of urinary incompetence in dogs and cats. Usually carried out with a pressure-measuring device in the tip of a catheter placed in the urethra and bladder.
the extension of the urethra beyond the end of the glans penis. In the horse it is mostly concealed in the urethral fossa. In small ruminants it is in the form of a 1 to 2 inch long filiform appendage and is easily injured during shearing, interfering with the animal's subsequent fertility.
protrusion of urethral mucosa at the end of the penis.
a synthetic conduit used in the treatment of urethral stricture or obstruction in cats, particularly following an unsuccessful urethrostomy.
proximal urethral ulceration
causes hematuria at the end of urination in horses.
see urethral perforation (above).
urethral sphincter mechanism incompetence
a cause of urinary incontinence in female dogs and occasionally cats.
caused by trauma, particularly injury associated with urethral calculi or urethral surgery. Clinically similar to obstruction except that the condition is subacute or chronic and characterized by a persistently distended bladder, dribbling of urine and the passage of a thin stream, usually accompanied by straining.
