Chronic kidney disease (CKD) is defined as a permanent abnormality in kidney structure or function that persists for more than 3 months (for example, glomerular filtration rate [GFR] <60 mL/min/1.73 m2 or albuminuria ≥30 mg/24 hours) and, it effects the 8% to 16% of the population worldwide.In pediatric patients with CKD, exercise capacity begins to decline in stage 3 of the disease and progressively decreases in stage 5, in dialysis and transplant patients (4, 5). Reduction in respiratory muscle strength and six minute walk test (6MWT) is observed in patients with CKD treated with hemodialysis (HD).The aim in present study is to evaluate the relationship between functional capacity and respiratory functions in stage 1-5 pediatric chronic kidney disease patients.

The aim of this study is to evaluate functional capacity with six minutes walk test (6MWT), respiratory functions with spirometer and the correlation between functional capacity and respiratory functions in pediatric CKD patients.
