We've curated a database of terms and conditions related to pediatric urology to help everyone learn more about the field.
UVJO is the result of an anatomic or a functional abnormality in the distal segment of the ureter.
UVJO can be complete or partial.
The cause of potential obstruction is thought to be a segment of distal ureter that is aperistaltic.
non-refluxing megaureters are seen.
of bilateral involvement in cases.
of neonatal hydronephrosis cases.
The diagnosis is confirmed with diuretic renography and ruling out VUR with voiding cystourethrogram.
As many as 70% to 80% of non- refluxing megaureters resolve spontaneously over time, making surgical intervention for congenital UVJ obstructions rare.
Non-refluxing megaureters with delayed drainage on diuretic renography are often observed.
Surgery is indicated in decreased renal function, UTIs, or other clinical indications.
Reimplantation with ureteral remodeling is the surgical intervention.
