Case presentation: 

A 43 years-old female visited urology outpatient department for persisted left ureter stone with renal colic, after attempted ureteroscopy lithotripsy in other hospital 3 weeks ago. At urology clinic, KUB showed left ureteropelvic junction stone and double J catheterization in the left collecting system. Urinalysis revealed RBC = 30-49/HPF and WBC = 6-9/HPF. Abdominal CT scan revealed double J catheter in situ but not over the stone. Retrograde Intrarenal Surgery with flexible ureteroscopy was performed. Incomplete duplication of collecting system with ureteral stone impaction in the lower moiety. Lithotripsy was done with holmium laser and a 4.8 Fr 26 cm double J catheter was implanted to the collecting system. Postoperative image of KUB showed stable double J catheter in the left collecting system with no radiopaque lesions. The patient recovered well and had follow up at urology outpatient department.

  

Discussion:

  Ureteral duplication is most common in females and may be incomplete or complete. Complications of  incomplete duplication is most often associated with ureteroureteral reflux or ureteropelvic junction obstruction of the lower pole of the kidney, which may also be associated with urinary stones. Incomplete duplication of collecting system may be difficult to detect preoperatively. During endoscopic surgeries, the lesions such as urinary stones or tumors may easily be neglected. Therefore, preoperative image study such as CT urography is helpful for diagnosis.
