A 2-month-old intact female English Cocker Spaniel weighting 2.8 kg was presented with pollakiuria and urinary incontinence. On the inspection, moisture around the perineum and hindlegs was observed with a mild urine odor. No other abnormalities were detected on physical examination. Retrograde vaginourethrography revealed the urachal remnant. The vesicourachal diverticulum was surgically removed without complications.

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.

The embryological and anatomical features of urachal anomalies have been well defined. Because of the variable clinical presentation, uniform guideline for evaluation and treatment are lacking. Although urachal remnants are rarely observed clinically, they often give rise to a number of problems such as infection and late malignant changes. Therefore, a total assessment of the disease with a particular focus on embryology, anatomy, clinical symptoms, as well as the most advisable management, is necessary. Twenty six patients with urachal remnants were treated at the Department of Pediatric Surgery from August 1980 to June 1998. Of these 26, 9 were classified as patent urachus 11 as urachal sinus, 4 as urachal cyst, 1 as urachal diverticulum and 1 as an alternating sinus. The group consisted of 11 males and 15 females. The age distribution was 20 neonates, 3 infants, 2 preschoolers and 1 adult. Infection was the most frequent complication and Staph. aureus was the predominant causative microorganism. Fistulogram was performed in 4 cases and ultrasound examination disclosed cysts or sinus in 7 cases. Excision was performed in 24 patients and incision and draniage in 2 cases as a primary treatment. There was no postopreative complication or recurrence.

Since urachal abnormalities are uncommon and have various clinical manifestations such as umbilical discharge, periumbilical pain, recurrent urinary tract infection and abdominal mass according to its structure, it is not easy to diagnose. We report our experience of a patient with urachal remnant abscess who presented with gross hematuria initially, and improved after the management with intravenous antibiotics and percutaneous drainage of abscess.

The urachus is a normal embryonic remnant of the primitive dome. It generally exists as a fibrous cord extending from the dome of the bladder to the umbilicus. Disorders of the urachus are developed as a result of its incomplete regression. The urachal cyst is the most common urachal anomaly, and is usually asymptomatic in infancy and childhood. However, when the cysts are large or accompanied with secondary infection, they may be detected in its early stage. A sonography or CT scan may be helpful to confirm the diagnosis of urachal cyst. The managements of infected urachal cyst are varied from simple drainage to radical excision. Here, we report an unusual case of urachal cyst infection that occurred during corticosteroids therapy in a girl with IgA nephropathy.

Purpose : It has been well known that urinary tract infection(UTI) in infants and children is frequently associated with vesicoureteral reflux(VUR). However, the publishied papers dealing with congenital anomalies associated with UTI emphasized the importance of VUR only. The aim of our study was to evaluate the type, incidence and spectrum of urologic anomalies associated with UTI. Methods : Medical records of clinical, bacteriologic and radiologic study were assessed retrospectively in 65 infants or children with documented UTI who were admitted to the Department of Pediatrics, Samsung Seoul Hospital from March 1996 to February 1998. Results : Spectrum of anomalies were associated with UTI as follows: VUR(n=23), both ectopic kidney(n=1), ureterovesical junction(UVJ) obstruction(n=1), multicystic dysplastic kidney(n=1), ureteropelvic junction(UPJ) obstruction with hydronephrosis(n=1), hutch diverticulum(n=1), UPJ stenosis(n=1), posterior urethral valve(n=1), urachal remnant(n=1) and bladder diverticula(n=1). Congenital urinary anomalies other than VUR were detected in 9 children among 65 patients with UTI(13.8%). 4 children among 9 congenital urinary anomalies other than VUR were combined with VUR. Sex distribution with congenital urinary anomalies other than VUR was more prevalent in male than female (7 males : 2 females). Age distribution at the time of UTI was less than 5 years in most patient (under 1 year in 1 patient, 1-2 year in 5 patients, 3-5 year in 1 patient, and above 5 year in 2 patients). And age distribution at the time of UTl associated with VUR was less than 5 years in most patient (under 1 year in 6 patients, 1-2 year in 8 patients, 3-5 year in 5 patients, and above 5 year in 4 patients), too Conclusion : Because congenital urinary anomalies other than VUR are seen in as high as 13.8% of patients, more careful evaluation of all possible congenital urinary anomalies as well as VUR is mandatory in pediatric patient with UTI.
