Efficacy and safety of circumcision alone on risk of febrile urinary tract infections in boys with posterior urethral valves: a prospective randomized open-label multicentric trial enriched with historic controls. CIRCUP 2
This research study, called CIRCUP 2, is investigating the best way to prevent urine infections that cause a fever in young boys who have a condition called Posterior Urethral Valves. This condition affects the tube that carries urine out of the body. The study wants to see if circumcision by itself is effective at stopping these infections, compared to other usual treatments like antibiotics. Researchers will be looking at how long it takes for a boy to get his first fever-related urine infection over two years. They will also check if any treatment affects kidney health and identify the types of germs causing these infections. The goal is to find safer and more effective ways to protect these children.
At a glance
What is this study about?
Imagine your child has a condition called Posterior Urethral Valves (PUV). This means there's a blockage in the tube that carries urine out of his body. This can make it harder for him to pee and can sometimes lead to urine infections. These infections can be serious, especially if they cause a fever, and can sometimes affect the kidneys.
This study, called CIRCUP 2, is trying to find the best way to stop these fever-related urine infections in boys with PUV. Currently, doctors often use antibiotics to prevent these infections. However, the study is asking if circumcision – a surgical procedure to remove the foreskin – could also be a helpful way to prevent these infections, either by itself or alongside antibiotics.
The main thing the researchers want to find out is how long it takes for a boy to get his first fever-related urine infection after starting one of the treatments. They'll follow the boys for two years. They also want to understand if a treatment affects kidney health, how many infections occur, and what types of germs cause them. By comparing different approaches, the study hopes to discover better ways to protect these boys from serious infections and keep their kidneys healthy.
Key takeaways
- This study compares circumcision to antibiotics for preventing urine infections in boys with PUV.
- It aims to find the safest and most effective way to protect these children.
- Participation involves regular check-ups and urine tests for two years.
- Treatments are assigned randomly, meaning your child might receive circumcision, antibiotics, or both.
- The study also looks at kidney health and the specific germs causing infections.
Who may be eligible?
This study is specifically looking for boys who have a condition known as Posterior Urethral Valves (PUV).
If your son has been diagnosed with PUV, he might be able to take part in this research. The study is open to boys of any age who have this condition. Only male participants are being recruited for this particular study.
The healthcare team will check other details from your son's medical history to make sure he's suitable and that the study is safe for him to join. They will explain everything clearly during the initial assessment.
Could this study suit you?
Answer these quick questions to see if you may be eligible. This is a guide only — the research team makes the final call.
- Is my child a boy?
- Does my child have a diagnosis of Posterior Urethral Valves (PUV)?
- Am I able to commit to regular hospital visits for two years?
- Am I comfortable with my child potentially receiving a circumcision or specific antibiotics as part of the study?
What does participation involve?
If your child takes part in this study, he would be randomly assigned to one of several treatment groups. This could mean receiving circumcision alone, antibiotics alone (like Bactrim, Alfatile, or Augmentin), or a combination of both. You wouldn't choose which group he is in, as this is decided by chance, like flipping a coin, to ensure fairness in the study. Your child would likely have regular doctor's visits over a two-year period. During these visits, the doctors will regularly check for fever-related urine infections. This would involve checking his temperature and taking urine samples, possibly using a small tube (catheter) or needle (suprapubic aspiration) to get a clean sample. They will also monitor his general health and may perform kidney scans to check for changes. The total duration of active follow-up for the main part of the study is two years.

Common questions
What are Posterior Urethral Valves (PUV)?
PUV is a condition in boys where there's a blockage in the tube that carries urine out of the body, making it hard to pee and increasing the risk of infections.
What is a 'fever-related urine infection'?
It's a urine infection that causes a high temperature (over 38.5°C) along with signs of infection in the urine and other inflammatory markers in the blood.
What is 'circumcision'?
Circumcision is a common surgical procedure where the foreskin, the skin covering the tip of the penis, is removed.
Will my child automatically receive a circumcision if we join?
Not necessarily. Your child would be randomly assigned to a treatment group, which could include circumcision, antibiotics, or a combination. The researchers will explain the options.
How long will my child be in the study?
The main part of the study involves following your child for a period of two years to see how the treatments work over time.
