Associations between lower urinary tract dysfunction and health-related quality of life in children with chronic kidney disease.

Aim: Little is known about the health-related quality of life (HRQoL) of children with lower urinary tract dysfunction (LUTD) and chronic kidney disease (CKD). We investigated LUTD and other possible predictors of impaired HRQoL in children with conservatively treated moderate-to-severe CKD or with a kidney transplant.
Methods: All 64 children with CKD or a kidney transplant treated at Karolinska University Hospital, Stockholm, Sweden, between June 2011 and December 2012 were approached and 59 children aged 8-18 were enrolled in the study. Lower urinary tract function was evaluated with voiding history, frequency and volume chart, uroflowmetry and postvoid ultrasound measurements. Self-reported HRQoL was assessed with validated generic instruments.
Results: The HRQoL of the study cohort was as good as the general paediatric population, apart from the physical and psychological well-being dimensions, and was no different to children with other chronic conditions. Urinary incontinence, but not LUTD in general, was associated with impaired HRQoL, as was having a kidney transplant and being female in some dimensions.
Conclusion: LUTD was common in children with CKD or a kidney transplant but did not affect their general HRQoL. Predictors of impaired HRQoL included incontinence, having had a kidney transplant and being female.
