Diurnal enuresis is daytime wetting (functional daytime urinary incontinence).Nocturnal enuresis is nighttime wetting. Enuresis is defined as the involuntary voiding of urine beyond the age of anticipated control.
Nocturia is defined by the International Continence Society (ICS) as "the complaint that the individual has to wake at night one or more times for voiding (i.e., to urinate)". [1] The term is derived from Latin nox – "night", and Greek [τα] ούρα – "urine". Causes are varied and can be difficult to discern. [2]
Urination, or voiding, is a complex activity. The bladder is a balloon-like muscle that lies in the lowest part of the abdomen. The bladder stores urine and then releases it through the urethra, which is the canal that carries urine to the outside of the body. Controlling this activity involves nerves, muscles, the spinal cord and the brain.
Nocturnal enuresis usually presents with voiding of urine during sleep in a child for whom it is difficult to wake. [7] [8] It may be accompanied by bladder dysfunction during the day which is termed non-mono symptomatic enuresis. [9] Day time enuresis, also known as urinary incontinence, may also be accompanied by bladder dysfunction.
Osmotic diuresis is the increase of urination rate caused by the presence of certain substances in the proximal tubule (PCT) of the kidneys. [2] The excretion occurs when substances such as glucose enter the kidney tubules and cannot be reabsorbed (due to a pathological state or the normal nature of the substance).
A meta-analysis on the influence of voiding position on urodynamics in males with lower urinary tract symptoms showed that in the sitting position, the residual urine in the bladder was significantly reduced, the maximum urinary flow was increased, and the voiding time was decreased. For healthy males, no influence was found on these parameters ...
