Examplesofurethralurethral These changes are attributed to decreasedurethralvascularization, to a decrease in alpha-adrenergic receptors and to smooth muscle tissue atrophy. From theCambridge English Corpus The aim of initial investigations therefore is to identify the group of infants at greatest risk - principally boys withurethralvalves or severe primary reflux. From theCambridge English Corpus Because of the morbidity and cost of invasive surgery, there have also been attempts to increaseurethralresistance by more conservative measures. From theCambridge English Corpus This would lead to decreasedurethralclosure pressure, predisposing the patient to the appearance of stress incontinence. From theCambridge English Corpus There is general consensus that maximumurethralpressure, maximumurethralclosure and length of the functional urethra decrease with age in women. From theCambridge English Corpus The lowerurethralpressure may not compensate for the rise in intravesical pressure in pregnancy. From theCambridge English Corpus Urethralpressure is maintained at a higher rate during filling, by contraction of muscle fibres within the bladder neck and urethra. From theCambridge English Corpus If faecal loading andurethralobstruction due to prostatic hypertrophy have been excluded, then use of intermittent catheterization should be considered. From theCambridge English Corpus Other neurological disease, or bladder disease (lithiasis, neoplasia, infection), or bladder-outlet obstruction (prostatic hyperplasia,urethralstenosis) may also be contributory. From theCambridge English Corpus When theurethralatrophy is extensive, the patient may notice an urge sensation. From theCambridge English Corpus Three had increases in bladder capacity, a fall in bladder pressure at capacity and increase inurethralpressure. From theCambridge English Corpus Caesarean section was associated with a decrease in the internal core of theurethralsphincter but not the rhabdosphincter. From theCambridge English Corpus Conventional micturating cystourethrography remains the gold standard for initial evaluation since, unlike indirect isotope cystography, it permitsurethralvisualisation and grading of reflux. From theCambridge English Corpus It is probably multifactorial but related largely to nerve damage and/or an alteration in the physiology and structure of theurethralsphincter. From theCambridge English Corpus Incontinence results when the intravesical pressure exceeds the pressure exerted by theurethralsphincter.
