Renal Duplex Systems


  
Case of Bilateral Renal Duplex System

Patient is a 36year old female, with h/o right ureterocele excision. 

USG was done initially, in which there was a tubular anechoic structure in right adnexa, mimicking a Hydrosalpinx. TVS confirmed the structure to be a dilated lower ureter, which was showing peristalsis and was seen in continuity with the right VUJ. This type of Ureteric Dilatation (Possibly secondary to reflux) can be easily mistaken for a hydrosalpinx. See the link below.

 CASE REPORTS: 'Duplex Megaureter Misdiagnosed as a Hydrosalpinx on Ultrasound '

Since there was right upper calyceal dilatation, Right Duplex System was suspected. LK was normal at time of USG.



LK shows two ureters

LK shows two ureters






CT images showed bilateral entirely duplicated ureters, bilateral upper moeity hydronephrosis. Right superior moeity ureter was seen inserted at a lower than normal position, with abnormal segmental dilatation of the distal 8-9cm.
