A Maltese (case 1) and a Labrador Retriever (case 2) presented with urinary incontinence. General conditions were good and screening tests, including a complete blood count, serum chemistry and radiography, were performed. Excretory urography was conducted, and fluoroscopy was performed for case 1 and computed tomography was performed for case 2. The dogs were diagnosed as right extramural ectopic ureter in case 1 and bilateral intramural ectopic ureter in case 2. We performed surgical corrections, including a neoureterocystostomy for extramural ectopic ureter and neoureterostomy for intramural ectopic ureter. After surgery, the dogs were catheterized with an indwelling catheter for 3 days. Urinary incontinence improved completely and the clinical outcomes were good. The choice of adequate surgical procedure is important for correcting ectopic ureters in canines.

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.

환아는 4개월부터 직장 탈출증과 심한 변비를 보였으며, 9개월에 질로부터 대변이 배출되는 증상을 나타냈으나 검사상 우측 이상 형성 콩팥 및 이소성 요관 이외 특이 소견이 없어 경과 관찰을 시행하였다. 16개월에 전신 마취하에 이학적 검사를 시행하여 누공을 확인하였고 이를 통한 대장 조영술에서 직장 중복증을 진단하여 수술을 시행하였다. 수술 시야에서 직장부터 횡행 결장에 이르는 관형의 뒤창자 중복을 확인하고, 직장-질 누공을 분리하고 결장 및 직장에는 중격절개술을 시행하였으며, 동반된 기형인 이소성 요관과 무기능 우측 신장은 절제하였다. 환아는 수술 후 3년간 잘 지내고 있다. 직장-질 누공을 동반한 관형의 뒤창자 중복은 매우 드문 선천성 기형으로 저자들의 경험을 문헌 고찰과 함께 보고하는 바이다.

Ureteropelvic junction obstruction and duplicated collecting system are common urologic anomalies in upper urinary system, but they seldom occur in combination. These obstruction can occur in both partial or complete duplicated collecting system. Complete duplication of the ureter may be asymptomatic or recognized when complications develop as a result of reflux into the lower pole ureter or obstruction of the upper pole with an ectopic ureterocele. It is difficult to choose an optimal therapy due to the high variability in function, degree of obsturction, damage and potential fir regeneration in growing kidney. We report our experience of successful surgical interventions in the ureteropelvic junction obstruction of the lower pole with complete duplicated collecting system.

Gastrointestinal duplications are rare congenital malformation that may require surgical intervention in the neonate, infant, and occasionally the older child. Symptoms produced by duplications vary according to their location, size, type and histology. We report the clinical characteristics and the surgical results of 9 cases of the gastrointestinal duplications treated at at Asan Medical Center between 1989 and 2000. Five patients were boys and four were girls; age of patients ranged from 5 days to 10 years. Eight duplications were cystic and one was tubular. One involved the stomach; five were in the ileum, and two in the cecum. The most common presentation was intestinal obstruction. There was associated anomaly in one patient, pulmonary sequestration and double ureter. Ectopic gastric mucosa was found in two. All patients underwent surgical resection. There was no perioperative mortality or morbidity. Although gastrointestinal duplication is a rare entity. consideration of associated anomalies and being familiar with the anatomy and clinical features are required for adequate management. In cystic form. complete excision is recommended but planned surgery is required for long segment tubular lesion.

Purpose : Renal duplication is a common occurrence, and the range of ureteral and renal anomalies draining the two poles of the duplex kidney leads to a variety of clinical presentations. Method : A series of 61 children with duplicated systems was studied retrospectively who were admitted during last 12years. Results : Of the children $60.6\%$ were accompanied with urologic anomalies that required surgical treatment, and most children initially were presented with urinary tract infection. $42.6\%$ of children were either diagnosed incidentally during evaluation of other non-urologic disease or during follow-up evaluation of abnormal antenatal renal sonogram. Conclusion : From our point view, children with history of abnormal antenatal renal sonogram, or with symptoms such as urinary tract infection, hematuria, abdominal pain should be evaluated radiologially fully to confirm further abnormality and accompanied complications. And routine follow-up using abdominal ultrasonogram, VCUG, and urine culture should be used to prevent and detect early treatable complications.

A castrated male Yorkshire Terrier dog was presented for urinary incontinence and constipation. On physical examination, the dog showed difficult urination. There were no neurological abnormalities and no bacterial detection on urinalysis. Rectal examination revealed a regular, normal-sized prostate. Urethral catheterization was performed easily. Excretory urography and retrograde positive contrast urethrocystography showed displacement of the urinary bladder to the intrapelvic region. There was no evidence of an ectopic ureter. A tentative diagnosis of urethral sphincter mechanism incompetence accompanied with a pelvic bladder was made. Cystopexy was decided to place the urinary bladder to its normal position. The neck of the urinary bladder was anchored to the body wall and prepubic tendon using mattress sutures. Additional sutures were placed to appose the lateral part of the urinary bladder and abdominal wall. A simple interrupted suture was placed to tack the apex of the urinary bladder on the abdominal incision line. A urinary catheter was placed in the urinary bladder to provide post-operative evacuation. The catheter was removed when the dog was able to urinate with minimal straining at 3 days post-operatively. The owner reported that the dogs showed normal urination without straining at 3 days after the catheter was removed. Excretory urography revealed that the urinary bladder was located on its normal position at 2 months post-operatively. Subsequent communication with the owner by telephone revealed that the dog was in good urination at 3 years 11 months post-operatively.
