Description of intervention(s) / exposure
Premature babies will undergo ultrasound kidneys, eye examination ,blood test for renal function and urine analysis twice ( at 32 weeks corrected age and a at 38 weeks corrected age). The investigations will take approximately 1 hour on each occasion. The total duration of the study is for 24 months

Comparator / control treatment
A group of term babies ( born after 37 completed weeks) will undergo ultrasound kidneys, eye examination ,blood test for renal function and urine analysis as premature baby but only once . The testing will be done in the first week of life and the duration all the tests would be approximately 1 hour.The total duration of the study is for 24 months
Control group
Active

Outcomes
Primary outcome [1] 258980 0
Kidney volume will be calculated by measuring the width, thickness and length of the kidney. The estimated glomerular filtration rate (eGFR ) would be calculated using serum creatinine and Cystatin C levels.

Summary
Brief summary
The main focus of this study is to look at the effect of prematurity on kidney growth and function . Kidney size and function in a cohort premature babies (< 32 weeks) is compared with control group (term babies).The study also looks at the rate of kidney growth when a baby is born premature .It will also determine if retinal vasculature ( arterial/venous diameter and branching angles) has correlation to kidney size , kidney function , baby's sex and ethnicity. Most literature says that the foetal retinal matures by 36 to 37 weeks gestation . Baby with significant Retiopathy of prematurity (ROP) will be excluded from analysis .
