Flashcards in 5. Duplex collecting system - Congenital solitary functioning kidney Deck (6):
1

Duplex collecting system - mechanism / definition

Bifurcation of ureteric bud before it enters the metanephric blastema creates a Y-shaped bifid
ureter. Duplex collecting system can alternatively occur through two ureteric buds reaching and
interacting with metanephric blastema.

2

Duplex collecting system - is strong ly associated with

1.vesicoureteral reflux and/or
2.ureteral obstruction,
3. Increase risk for UTIs.

3

Congenital solitary functioning kidney - definition / mechanism

condition of beiing born with onely one functional kidney

4

Congenital solitary functioning kidney - clinical presntation

Majority asymptomatic with
compensatory hypertrophy of contralateral kidney, but anomalies in contralateral kidney are
common.

5

To what anomaly does bifurcation of the uteric bud before it enters the metanephric blastema lead?

Duplex collecting system

6

A 4-year-old has vesicoureteral reflux and multiple UTIs because of asynchronous muscle contraction. What is the developmental pathogenesis?

Duplex collecting system caused by bifurcation of the ureteric bud before it enters the metanephric blastema, result in a bifid ureter
