From January 1982 to December 1990, there were 229 cases with 337 ureters having vesicoureteral reflux (VUR). Thirteen of them (3.86%) were also found to have ureteropelvic junction (UPJ) obstruction in the same ureter. They were categorized into three groups based on the therapeutic implications. Group 1 (two ureters) underwent pyeloplasty. Group 2 (two ureters) received both pyeloplasty and reimplantation. The remaining nine ureters having VUR and pseudo-obstruction fell into group 3, and two of them became true UPJ obstruction eventually. We stressed the importance of evaluating upper urinary tract in all refluxed ureters with inappropriately dilated renal pelvis. By doing that we can avoid unnecessary surgery and prevent complications from wrong sequence of operation to a least extent.

Extracorporeal shock wave lithotripsy (ESWL) has been proved to be an effective method of treating upper urinary tract calculi. However, there is little experience with the use of this approach in pediatric urolithiasis, especially for lower urinary tract calculi. Nine children, aged 1-18 years, were treated here with urolithiasis in the renal pelvis, lower ureter and bladder, using Dornier MFL 5000. A polystyrene plate was used to protect small children from chest damage. Prone position was routinely used to treat lower ureteral and vesical calculi, thus avoiding bony pelvis blockage of shock wave energy. Excellent pulverization was achieved in eight cases; fragmentation in only one case, then required cystolithotripsy for bladder stone fragments three months after ESWL. No patient had melena. Neither hemoptysis nor gastrointestinal complications were seen. Extracorporeal shock wave lithotripsy is a safe and effective method of treating urinary tract calculi in children.

Ten cases of duplex kidney with ectopic ureterocele were detected by ultrasound in the recent four years. There were eight girls and two boys. One case was found to have bilateral ectopic ureterocele, the others were unilateral. Urinary tract infection was found in five cases, urinary dribbling was told in one case, and the other four cases were asymptomatic. The age distribution ranged from newborn to 15 years. Six cases received surgery, and the other four cases were followup at O.P.D. In these cases, the sonography could identify the hydronephrotic nature of the upper pole moiety. Dilatation of the upper pole ureter could be demonstrated. A sonolucent intravesical cystic mass also could be outlined. In this series, five cases with residual parenchyma were assessed by ultrasonography, and two cases with pus formation in the upper pole collecting system were detected. On intravenous urogram, the affected upper pole moiety was not or poorly visualized in these cases, thus produced some diagnostic challenges. Ultrasonic examination is an excellent method to identify a fluid-filled cystic structure, and can provide a simple and non-invasive technique for confirmation of ectopic ureterocele, which is independent of renal function. Therefore, it has become an important modality in the detection, diagnosis and followup of this anomaly.

Congenital megacalyces is a calyceal anomaly characterized by nonobstructive dilatations of the calyces, associated with hypoplasia of the medullary pyramids. In the past three years, seven patients with congenital megacalyces were found incidentally during renal ultrasonic examination. There were five boys and two girls who were asymptomatic, except for a case with hematuria. Three cases presented bilateral and four unilateral, ages ranged from 7 to 14 years. In this series, all cases with dilatations of the calyces were initially detected by sonography, and then confirmed by other radiologic examinations. On intravenous urography, contrast material was visible at the normal time, but prolonged opacification. The radiological features presented widen calyces, flattened papillae, absence of papillary tips and usually no significant dilatation of the renal pelvis and ureter. The renal medulla had become thin. An ultrasound examination showed the kidneys with dilated calyces and decreased parenchyma. Renal pelvis and ureter were mostly normal in size. Diuretic radionuclide renogram T1/2 was performed in five cases, to disclose nonobstructive lesions. Radionuclide cystography, underwent in three cases, revealed no reflux phenomenon. Renal function was normal in all cases. Congenital megacalyces are a non-progressive lesions. Therefore, it is important to recognize the clinical entity and avoid unnecessary surgery. Since sonography is a noninvasive modality, it can serve as a tool for long-term follow-up of these patients and for the detection of possible future stone formation.

Two girls, each with a single ectopic ureter inserted into the proximal urethra, are reported. Abdominal ultrasonography showed that the involved kidneys were small and hydronephrotic. The associated ureters were dilated and opened into the proximal urethra. Diagnosis was confirmed by voiding cystourethrogram.

Two cases of duplex kidney with ectopic urethral ureter are reported. Using abdominal ultrasound, the poorly functioning upper pole pelvis of the involved kidney was found to be sonolucent which may have been misinterpreted for a simple renal cyst. The corresponding ureter was dilated and drained into the proximal urethra. Ultrasound is an ideal imaging modality in the assessment of children with a duplicated renal system and may provide detailed information about this structural anomaly, such as the exact insertion of the ectopic ureter.
