Posterior urethral valve (PUV) in Thai boys often presents with urinary tract infections (UTIs). Recurrent UTIs and chronic kidney disease (CKD) are common complications, highlighting the need for lifelong monitoring.
Area of Science:
- Pediatric Nephrology
- Urology
- Congenital Abnormalities
Background:
- Posterior urethral valve (PUV) is the most common congenital bladder outlet obstruction in boys.
- PUV can lead to significant renal damage starting in utero.
- Limited data exists on long-term PUV outcomes in Thailand.
Conclusions:
- Urinary tract infections are the most frequent initial presentation of PUV in Thai boys.
- Recurrent UTIs and the development of chronic kidney disease are the most common adverse outcomes.
- Lifelong follow-up for renal and bladder function is crucial for all patients diagnosed with PUV.
