The prevalence of contralateral renal abnormalities in noncystic-dysplastic kidney (NCDK) disease and renal agenesis is unknown. Twenty-four patients with NCDK disease and 16 patients with renal agenesis were studied in this 11-year retrospective study. In all patients the urinary system was evaluated by renal ultrasonography, and excretory urography or radionuclide scan. In addition, voiding cystourethrography was performed in 21 of 24 patients with NCDK disease and in 10 of 16 patients with renal agenesis. In those patients where voiding cystourethrography was performed, 14 (67%) patients with NCDK disease and 9 (90%) patients with renal agenesis had contralateral urologic abnormalities. Contralateral vesicoureteral reflux was the most common contralateral abnormality identified in 9 (43%) patients with NCDK disease and in 3 (30%) patients with renal agenesis. It is concluded that contralateral urologic abnormalities are common in patients with NCDK disease and in patients with renal agenesis and that vesicoureteral reflux is the most common contralateral abnormality noted.

Objective: Congenital heart diseases in childhood are an important cause of morbidity and mortality. The frequency of non-cardiac anomalies in children with congenital heart diseases is between 7-50%. Urinary system anomalies are an important risk factor in children with congenital heart diseases. The aim of this study was to evaluate the presence, types and frequency of urinary system anomalies detected during cardiac catheterization in children with congenital heart diseases. Methods: The cineurography records of 6000 patients who underwent cardiac catheterization due to congenital heart diseases were retrospectively analyzed. Urinary system anomalies detected were examined as renal agenesis, renal ectopia, renal fusion, dysplastic kidney, obstructive uropathy, vesicoureteral reflux, ureter anomaly and bladder anomaly. Patients were grouped as right ventricular outflow tract obstruction, left ventricular outflow tract obstruction, left-to-right shunted hearth disease and, cyanotic or complex heart diseases. The groups were compared in terms of urinary system anomaly types. Results: Seventy-six patients (47 male and 29 female) with urinary system abnormalities were detected. Obstructive uropathy was found in 43 (56.5%) patients, renal agenesis was found in 14 (18.4%) patients, ureter anomaly was found in 14 (18.4%) patients, renal fusion was found in 3 (3.9%) patients, renal ectopia was found 1 (1.3%) patient, vesicoureteral reflux was found in 1 (1.3%) patient. There was no significant difference in term of the urinary system anomaly types among the groups (p>0.05) Conclusion: Urinary system anomalies may also be frequently accompanied in children with congenital heart diseases, so urinary system should also be evaluated during the cardiac catheterization procedure.

To establish prevalence of some renal abnormalities in schoolchildren, an epidemiologic study of 132 686 schoolchildren, including 69 903 boys and 62 783 girls, was conducted from March 1987 to May 1988 in the city of Taipei. At the health station of each school, the students were screened quickly by a physician with portable real-time ultrasound equipment. When a renal abnormality was detected or suspected, the examinee was referred to Taipei Municipal Women and Children's Hospital for further investigation. Radiologic and urologic procedures were then selectively performed to establish the correct diagnosis. Renal abnormalities were detected in 645 students (approximately 0.5% of total population screened). There were 256 cases of hydronephrosis, 103 cases of unilateral renal agenesis, 128 cases of unilateral small kidney, 90 cases of renal cystic disorders, 30 cases of ectopic kidney, and 38 cases of other abnormalities. Surgically correctable lesions were demonstrated in 50 of these students. Rapid renal ultrasonography was found to effectively detect some renal abnormalities initially, and prevalence could then be established after further investigations.

Introduction: This study evaluates the accuracy of renal ultrasonography (US) in the detection of vesicoureteral reflux (VUR) compared to voiding cystourethrography (VCUG).Methods: We retrospectively reviewed the medical records of 131 children with urinary tract infection. Ultrasound findings were considered to be suggestive of VUR if a “pelvocalyceal dilatation”‚ “retrovesical ureteral dilatation” and/or an “increase in one or both kidneys’ size” were reported.Results: Ultrasound findings were positive for VUR in 5 of 24 patients with confirmed VUR on VCUG, and were negative in all of 107 patients without VUR on VCUG. Altogether, of the 131 children‚ 24 had reflux on VCUG, 19 (79%) of who had no sonographic findings suggestive for reflux. The sensitivity and specificity of ultrasound in Suggesting VUR were 20% and 100%, respectively.Conclusion: The results of this study showed that ultrasonography cannot accurately detect or predict vesicoureteral reflux. This outcome should be mentioned by clinicians in evaluation of patients with complaints which are suggestive for VUR.

In Reply.— In our article, we reported on 645 renal abnormalities found in 132 686 school children screened through the use of renal ultrasonography. Of those with renal abnormalities, 50 patients had surgically correctable lesions. The other 595 cases have been examined fully to establish the correct diagnosis and the prevalence of renal abnormalities in school children. However, in this study, the cost to benefit ratio was determined by total expense to number of surgically treatable diseases.

BACKGROUND: Vesicoureteral reflux (VUR) represents a common pediatric anomaly in children with an upper urinary tract infection (UTI) and is defined as a retrograde flow of urine from the bladder into the upper urinary tract. There are many diagnostic options available, including voiding cystourethrography (VCUG) and contrasted-enhanced urosonography (ceVUS). ceVUS combines a diagnostic tool with a high sensitivity and specificity which, according to previous study results, was even shown to be superior to VCUG. Nevertheless, despite the recommendation of the EFSUMB, the ceVUS has not found a widespread use in clinical diagnostics in Europe yet. MATERIALS AND METHODS: Between 2016 and 2020, 49 patients with a marked female dominance (n = 37) were included. The youngest patient had an age of 5 months, the oldest patient 60 years. The contrast agent used in ceVUS was SonoVue®, a second-generation blood-pool agent. All examinations were performed and interpreted by a single experienced radiologist (EFSUMB Level 3). RESULTS: The 49 patients included in the study showed no adverse effects. 51%of patients (n = 26) were referred with the initial diagnosis of suspected VUR, while 49%of patients (n = 23) came for follow-up examination or to rule out recurrence of VUR. The vast majority had at least one febrile urinary tract infection in their recent medical history (n = 45; 91,8%). CONCLUSION: ceVUS is an examination method with a low risk profile which represents with its high sensitivity and specificity an excellent diagnostic tool in the evaluation of vesicoureteral reflux, especially in consideration of a generally very young patient cohort.

INTRODUCTION Positional installation of contrast cystography (PIC cystography) represents a new method to identify vesicoureteral reflux (VUR) that is unrevealed by standard diagnostic procedures. It is performed by radiological examination of the vesicoureteral junction during cystoscopic installation of the contrast medium at the ureteral orifice. OBJECTIVE We studied the significance of PIC cystography to demonstrate VUR that failed to be revealed by standard voiding cystourethrography (MCUG), as well as the degree of the correlation of such a finding with endoscopic appearance and the position of the ureteral orifice (UO). METHOD The aim of the paper was to analyze a sample of 5 children (4 girls and 1 boy), aged 6-15 years (mean 9.8 years) with recurrent febrile urotract infections, complicated with scarring changes of the renal parenchyma and normal findings on MCUG. The grade of VUR demonstrated by PIC cystography was classified using the standard hydrodistensional scale. RESULTS All 5 patients had VUR, disclosed by PIC cystography, of whom in 4 it was unilateral and in one bilateral. Of 5 patients, 4 had VUR grade I and one grade II. All the children with VUR detected by PIC cystography also had evident cystoscopic abnormalities in the position and/or configuration of the ureteral orifice at the same side, while at the side with normal finding on PIC cystography, the endoscopic finding was also within normal limits. CONCLUSION PIC cystography is the method of choice in the confirmation of VUR as the cause of recurrent urotract infection and its complications in children with a normal finding on standard MCUG. In all our patients with VUR verified by PIC cystography, at the same side we also revealed endoscopic changes in the position and/or configuration of UO.

Objective: Demographical, pre-transplantation and post-transplantation features and post-treatment results of four pediatric cases, who had vesicoureteral reflux (VUR) in the graft kidney, were discussed. Methods: Transplantation age, primary diagnosis, VUR to pretransplantation in native kidneys, history of bladder dysfunction, bladder capacity, results of urodynamic studies, donor and its features, induction treatments and ongoing immunosuppressive treatments, acute rejection episodes, CMV and BK infections, VUR grade in the renal graft, DMSA results, treatment type and its outcomes, and the renal graft functions of four patients who underwent kidney transplantation at Tepecik Training and Research Hospital between 2008 and 2016 and for whom VUR was determined via voiding cystourethrography (VCUG) due to recurrent urinary tract infections, were evaluated. Results: All of four cases were female. Their mean transplantation age was 8.7 years (5-16). High grade (Grade 4) VUR was determined in the graft kidney in all but one. DMSA included multiple scar foci apart from one case having low grade VUR. Cases were primarily treated endoscopically and then by open surgery. Spontaneous recovery occurred in one case. Graft dysfunction was not observed in any of the cases. Conclusion: VUR is an important risk factor in recurrent urinary tract infections after post-transplantation. A special assessment should be done for the patient in the presence of VUR and conservative and surgical treatments should be executed together. It should be remembered that VUR can be spontaneously regressed by the bladder capacity increasing treatments and prophylaxis.
