An intact male, 3-month-old, Great Pyrenees mountain dog, weighing 7.3 kg with a history of severe hematuria during 2 months was referred. Hematology showed mild leukocytosis. There were no remarkable findings in abdominal radiographs due to ingesta and gas in the gastrointestinal tracts. Ultrasonographs showed bilateral hydronephrosis, bilateral dilated and tortuous ureters, and hyperechoic sludges in the urinary bladder (UB). And a dilated cavity was identified cranial to the UB. Excretory urography and cystography were performed to examine the cause of hydronephrosis and an abnormal cavity cranial to the UB. Bilateral ureters were tortuously dilated and opened into the craniodorsal part of the UB. An abnormal cavity was connected to the UB at the left cranioventral part of the UB. Therefore bilateral ectopic ureters and urachal remnant were diagnosed.

말티즈(증례1)와 라브라도 레트리버(증례2)가 요실금 증상으로 내원하였다. 전신상태는 양호하였으며, 혈액혈청검사 및 방사선검사상에서 이상소견은 나타나지 않았다. 증례 1에서는 투시검사, 증례2에서는 컴퓨터 단층촬영을 통해 배설 요로조영검사를 실시하였다. 증례1은 우측 강외성 이소성 요관으로, 증례2는 양측성 강내성 이소성 요관으로 진단되었다. 각각의 증례는 neoureterocytostomy (증례1)와 neoureterostomy (증례2)를 실시하였다. 술후, 3일동안 요관 카테터를 장착하였다. 술후 요실금 증상은 개선되었으며, 다른 임상증상은 나타나지 않았다. 개의 이소성 요관 형태에 따른 적절한 수술법을 통해 이소성 요관을 효과적으로 치료할 수 있었다.

난소를 제거한 57개월령의 golden retrieve개가 심한 배뇨실금을 나타내며 양측성 요관이소증으로, 좌측에는 통상적인 새요관개구술(neoureterostomy)로 방광삼각지대에 새로운 요관개구부를 만들었고 방광목에 위치한 우측요관의 개구부는 그 부위를 확장만 시킴으로써 수술 후 배뇨실금 증상을 교정할 수 있었다. 방광목확장개구수술방법은 본 증례에서 처음으로 개에 시도되어 좋은 수술결과를 나타내었고 요관개구부가 방광목인 이소증 치료에 효과가 있을 것으로 생각되며 지속적인 임상적용과 관찰이 요구된다.

Purpose: Ureteral duplication is a relatively common congenital urinary tract abnormality that can be associated with various clinical problems such as vesicoureteral reflux (VUR), hydronephrosis, and ectopic ureters. The purpose of this study was to analyze the clinical characteristics of pediatric patients with recently diagnosed ureteral duplication and to identify any differences from those described in previous reports. Methods: We retrospectively reviewed the clinical characteristics and course of pediatric patients who were diagnosed with ureteral duplication between January 2008 and June 2017. Results: A total of 32 pediatric patients were diagnosed with ureteral duplication during the study period. The male to female ratio was 1:2.2. Twenty-seven patients (84.4%) were first diagnosed with ureteral duplication at less than 3 months of age, and 26 (81.3%) were first diagnosed by prenatal ultrasonography. Four of the 32 patients were diagnosed with bilateral ureteral duplication, for a total of 36 occurrences of ureteral duplication. In 17 occurrences of complete ureteral duplication (47.2%), other urinary tract anomalies were also found; namely, ureterocele (7), VUR (11), and ectopic ureter (5). However, none of the patients with incomplete ureteral duplication had ureterocele or VUR. Conclusions: With the advent of routine prenatal ultrasound, ureteral duplication is being diagnosed earlier than was previously possible, enabling timely treatment of the various accompanying urinary tract anomalies. Multicenter studies are needed to establish guidelines for standardized evaluation and treatment of ureteral duplication.
