What is PUV surgery?
Table of Contents
A surgery called a valve ablation is the most common treatment for PUV. Valve ablation is a minimally invasive surgery which involves inserting a tiny telescope into the urethra. Physicians use the telescope tube to remove the excess tissue.
What is a PUV?
Posterior urethral valves (PUV) are obstructive membranes that develop in the urethra (tube that drains urine from the bladder), close to the bladder. The valve can obstruct or block the outflow of urine through the urethra.
What does PUV mean in pregnancy?
A posterior urethral valve (PUV) is a leftover flap of fetal tissue that is located in the urethra. The urethra is the tube that carries urine from the bladder out of the body.
How is PUV treated?
The most important treatment after the baby is born is to drain the bladder to take pressure off the kidneys. The bladder can be drained with a catheter or tube. Then when the baby is bigger, the PUV can be removed with surgery.
When is fetal surgery indicated for postpartum hemorrhage (PUV)?
Currently, fetal surgery for PUV should be considered only for fetuses who have a high risk of in uteroor neonatal death due to midtrimester severe oligohydramnios and who have both a normal karyotype and evidence of good renal function based upon fetal urinary evaluation. NEED FOREARLYREFERRAL
What are posterior urethral valves (PUV)?
Posterior urethral valves (PUV) are obstructive membranes that develop in the urethra (tube that drains urine from the bladder), close to the bladder. The valve can obstruct or block the outflow of urine through the urethra. When this occurs, the bladder, ureters and kidneys become progressively dilated, which can lead to damage.
What is the prognosis of posterior urethral valve intervention during pregnancy?
Conclusions: Fetal intervention for posterior urethral valves carries a considerable risk to the fetus with fetal mortality rate of 43%. The long-term outcomes indicate that intervention may not change the prognosis of renal function or be a predictor for possible urinary diversion.
How is PUV diagnosed during pregnancy?
PUV occur in varying degrees from mild to severe. Due to increased use of prenatal imaging, PUV may be identified before any symptoms are present. If any dilation (hydronephrosis) is identified, your baby will be monitored throughout the pregnancy and after birth. Once your baby is born, further imaging studies will confirm the diagnosis.
