Constipation: a cause of enuresis, urinary tract infection and vesico-ureteral reflux in children. 1985

S O'Regan, and S Yazbeck

The observation that constipation alone may induce uninhibited bladder contractions in children and is associated with recurrent urinary tract infection in childhood suggests an etiologic association. Rectal distension due to faecal retention in chronic functional constipation causes bladder distortion and may cause stimulation of detrusor stretch receptors resulting in detrusor peroneal dyssynergism. Distortion of the trigonal area may result in failure of ureteral valve competence and allow for vesico-ureteric reflux.

UI	MeSH Term	Description	Entries
D003248	Constipation	Infrequent or difficult evacuation of FECES. These symptoms are associated with a variety of causes, including low DIETARY FIBER intake, emotional or nervous disturbances, systemic and structural disorders, drug-induced aggravation, and infections.	Colonic Inertia,Dyschezia
D004775	Enuresis	Involuntary discharge of URINE after expected age of completed development of urinary control. This can happen during the daytime (DIURNAL ENURESIS) while one is awake or during sleep (NOCTURNAL ENURESIS). Enuresis can be in children or in adults (as persistent primary enuresis and secondary adult-onset enuresis).

D012189	Retrospective Studies	Studies used to test etiologic hypotheses in which inferences about an exposure to putative causal factors are derived from data relating to characteristics of persons under study or to events or experiences in their past. The essential feature is that some of the persons under study have the disease or outcome of interest and their characteristics are compared with those of unaffected persons.

D014552	Urinary Tract Infections	Inflammatory responses of the epithelium of the URINARY TRACT to microbial invasions. They are often bacterial infections with associated BACTERIURIA and PYURIA.

D014718	Vesico-Ureteral Reflux	Retrograde flow of urine from the URINARY BLADDER into the URETER. This is often due to incompetence of the vesicoureteral valve.
