An absent kidney is a condition where a person has only one kidney. It is also known as a solitary kidney, renal agenesis, or renal dysplasia.
What is Absent Kidney?
Why do some children only have one kidney?
There are several reasons why a child may only have one kidney:
- He or she may have been born with only one normal kidney. In many cases, this is discovered during a routine scan.
- The child may have had one kidney removed due to disease.
With proper monitoring and paediatric absent kidney treatment in Dubai, children with one kidney can still lead healthy, active lives.

How does the urinary system work?
The urinary system consists of the kidneys, ureters, bladder, and urethra. The kidneys filter the blood to remove waste products and form urine. Urine then flows from the kidneys down through the ureters into the bladder. From the bladder, it passes out of the body through another tube called the urethra during urination.
The ureters join the bladder at an angle, creating a flap-like valve. This prevents urine from flowing back into the ureters and kidneys (reflux) and protects the kidneys from the high pressure created during urination. This valve mechanism ensures that urine is expelled from the bladder in one direction, in a single flow.
Why does a child with one kidney need regular check-ups?
When a child is born with one normal kidney, he or she should have regular check-ups with a specialist doctor. Ongoing monitoring through paediatric absent kidney care in Dubai helps ensure the kidney is growing normally.
What are the risks of only having one kidney?
Studies have found that people with only one normal kidney are no more likely to develop kidney failure. Parents seeking reassurance can benefit from expert advice on paediatric renal agenesis treatment in Dubai.

Will children with one kidney need to follow a special diet?
A child with one kidney does not need to restrict his or her diet unless the remaining kidney is not completely normal. In such cases, the amount of salt and protein may need to be reduced. Families can seek guidance from a paediatric urologist in Dubai to ensure their child’s diet supports healthy kidney function.
Can children with one kidney participate in sports?
Children do not need to restrict their activities. However, some doctors recommend that children with one kidney avoid contact sports such as rugby or boxing.
