Docs can you explain what is a duplex kidney & should i still go on holiday if i still have a kidney infection?

Normal variant: Duplex kidney means your kidney drains via 2 ureters (tubes connecting kidney to bladder) but a single kidney, usually a little larger than a non-duplex kidney. Presence of kidney infection suggests possible urinary reflux from bladder to kidney. Worth checking with VCUG (bladder x-ray). No doubt on antibiotics (a) for infection & continue to take. Go & consider prophylactic as whilst on vacation.
