To present a rare case of prenatal bladder rupture secondary to posterior urethral valves (PUV) and systematically review similar cases.
Approach:
Case Report: A male patient with prenatal bladder rupture due to PUV was reported, detailing prenatal findings, postnatal treatment, and outcomes.
Systematic Review: A systematic review was conducted according to PRISMA guidelines, analyzing pediatric cases of bladder rupture associated with PUV.
Key Findings:
Prenatal imaging at 23 weeks showed bladder rupture with urinary ascites.
Postnatal treatment included endoscopic valve ablation, vesicostomy, and ileocystoplasty.
Prenatal diagnosis of bladder rupture was reported in 33% of reviewed cases, mainly in the third trimester.
Common prenatal findings included fetal ascites, hydronephrosis, and oligohydramnios.
Management typically involved urgent postnatal urinary decompression followed by valve ablation.
Interpretation:
Fetal bladder rupture in PUV is a rare and severe manifestation of lower urinary tract obstruction, with limited data suggesting preserved kidney function but frequent bladder dysfunction.
Limitations:
Data is limited to heterogeneous case reports.
Follow-up data on kidney and bladder outcomes are scarce.
Conclusion:
Multidisciplinary follow-up is essential for assessing kidney and bladder outcomes in patients with PUV-associated bladder rupture.
