title: [Detrusor pseudohyperactivity syndrome in children with constipation].
abstract: OBJECTIVE
  was the evaluation of dependencies occurring between constipation and observed nocturia, pressing tenesmus and daytime urinary incontinence.
  
  
  METHODS
  the studies were conducted in 51 children aged between 3 and 17 years including 25 girls and 26 boys hospitalized in the Clinical Department because of nocturia, pressing tenesmus and daytime urinary incontinence. In all children a complex diagnostic work up of the urinary system and the lower segment of alimentary tract was performed. Results of the examinations were compared to the control group.
  
  
  RESULTS
  analysis of the results of the conducted examinations indicates that the overblown rectal ampulla, through the pressure exerted on the urinary bladder, seemingly decreases its volume causing the occurrence of pressing tenesmus, nocturia and daytime urinary incontinence. This process leads to the formation of detrusor hyperactivity syndrome characterized by: chronic constipation, increase of miction frequency and simultaneous decrease of volume of each portion of urine, nocturia and/or daytime urinary incontinence.
  
  
  CONCLUSIONS
  chronic constipation disturbs the functional-morphological equilibrium between the end segment of alimentary tract and the urinary bladder. By influencing the process of filling and accumulation of urine in the bladder they lead to the formation of detrusor hyperactivity syndrome.
