“…Non-contrast CT scans are less likely to identify duplex ureters, especially without prior clinical suspicion [ 10 ]. However, a faceless renal appearance devoid of vascular or collecting system markings on a transverse CT section usually points to a duplex system [ 11 ]. Other investigations used in evaluating patients with duplex systems are voiding cystourethrography (VCUG) to check for vesicoureteric reflux and dimercaptosuccinic acid (DMSA) scans to assess scarring and function.…”

Ureteric calculi are common urological problems. However, the management of stone disease varies considerably with patient choice and anatomy. There are few reports about ureteral calculi in patients with unilateral complete duplex kidneys managed by ureteroscopy. We hope to increase the awareness of urologists when investigating patients with similar symptoms.We present the case of a 28-year-old man with recurring left flank pain. Non-contrast computed tomography (CT) scans of the kidney showed an impacted left vesicoureteric junction stone measuring 6 mm. Intra-operatively, a stone in the left duplex system was discovered. He was managed with ureteroscopy, laser fragmentation, and the insertion of ureteric stents.The case demonstrates the complexity of managing ureteric stones in a complete duplex kidney. We highlighted the diagnostic limitations of non-contrast scans in identifying duplex systems. It is important to consider contrast CT scans in patients with unusually persistent symptoms to outline the anatomy of the kidney and collecting systems.

“…This has important implications, especially in emergency cases where the wrong ureter may be stented, leaving the patient with an infected, obstructed system and sepsis requiring repeat imaging and procedures, as reported by H.H. Huang et al [ 11 ].…”
