Brief Summary

The bladder has a muscle that acts like a tap called the sphincter. Just like a tap, when pee is stored the sphincter muscle is closed and during peeing the sphincter opens. Sometimes the sphincter tap does not work properly and can cause problems. If the sphincter is weak there can be urine leak (incontinence). If the sphincter is too strong bladder might not empty properly. Children who require investigation of their urinary problems are usually assessed with non-invasive tests. Sometimes investigation is with a more invasive test videourodynamics or video cystometrogram (VCMG; this test requires the insertion of catheters into the bladder and rectum. This test provides only indirect information about sphincter function. It would be helpful to have a more direct test of the sphincter. It will allow better targeted treatments of sphincter problems which are often therapeutically challenging. Urethral pressure profile is a test used in adults to assess the sphincter. Although it has been described in children normal values have not been described. The research project is to define urethral pressure profile values in children and young people with normal, weak and overactive sphincters. Urethral pressure profile measurement is invasive as it requires the insertion of a special catheter. It will therefore be performed at the time of other invasive procedures eg VCMG or urology surgery under general anaesthetic. The study will be conducted at single site, which is a children's hospital. The study will be an observational case controlled study with three arms: controls, those with overactive sphincters and those with underactive sphincters. The study is intended to run over three years.

Sampling MethodNon-Probability Sample
Study Population

Patients attending paediatric urology or bladder clinic

You may qualify if:

  • Controls
  • Concurrent urological disease requiring surgery which includes cystoscopy
  • No significant urinary symptoms
  • No day-time urinary incontinence
  • Urinary frequency 4-7 per day
  • No history of recurrent urinary infections (more than two infections in previous year)
  • Has not passed a renal tract stone
  • Overactive sphincter
  • Require VCMG as part of their clinical care
  • A prior diagnosis of dysfunctional voiding. This will have been made in a neurologically intact child following previous non-invasive bladder investigation including two representative urine flows that demonstrate the following (Austin et al., 2014):
  • Intermittent and/or fluctuating flow rate
  • Pelvic EMG activity during voiding
  • either perform intermittent catheterisation or have no contraindication to Entonox sedation (see below)
  • Underactive sphincter
  • Have either:
  • +5 more criteria

You may not qualify if:

  • Unaccompanied by adult with parental responsibility who can give consent
  • Previous bladder outlet or urethral surgery
  • Contraindication to Entonox if sedation required for catheter insertion:
  • Conditions where gas may be trapped in a body cavity, eg middle ear occlusion, intestinal obstruction
  • Unable to understand instruction for use of Entonox
  • Evidence urinary tract infection on day UPP measurement
  • Symptoms of dysuria
  • Abnormally cloudy or offensive urine
  • Temperature of 38oc or more
  • Urine dipstick positive nitrates or leucocytes on the day of the study, in the absence of a renal tract stone or indwelling catheter
