[Possibilities of endoscopic treatment of primary vesicoureteral reflux].

INTRODUCTION: Vesicoureteral reflux, urinary infection and pyelonephritic scarring represent a well known triad in pediatric practice that may lead to severe scarring of kidneys, and development of so called reflux nephropathy. Apart from standard therapeutic options (conservative treatment and surgical therapy), endoscopic correction of refluxing vesicoureteral junction has been introduced into clinical practice. MATERIAL AND METHODS: This study included endoscopically treated patients with primary vesicoureteral reflux over a 9-year period, as well as certain clinical parameters. RESULTS: Endoscopic correction of primary vesicoureteral reflux with teflon paste has been successful in up to 93.5% of patients. After one application vesicoureteral reflux disappeared in 58.8% of cases. After two applications 86.0% of ureters were cured, whereas the third application had no further effect on existing reflux. Improvement with spontaneous regression of reflux was established in 7.5% of treated ureters. DISCUSSION: Endoscopic correction should be performed in all patients with third grade vesicoureteral reflux, and in selected patients with second and fourth grade reflux. First grade reflux should be treated conservatively, and fifth grade reflux should be treated surgically. CONCLUSION: Endoscopic treatment of primary vesicoureteral reflux is an easy, simple, fast and safe procedure that prevents regurgitation of urine from bladder to upper parts of the urinary system in most of cases.

[External genital abnormalities in male schoolchildren: an epidemiological study].

INTRODUCTION: External genital abnormalities represent the most common congenital anomalies. Proper, not delayed diagnosis and treatment of certain abnormalities (undescended testis, hypospadia, varicocele) is of great importance for future fertility potential of children. MATERIAL AND METHODS: An epidemiological study, that consisted of an urological checkup, was performed among school-aged boys in two elementary schools. Prevalence of external genital, and inguinal region was examined. RESULTS: A total of 1229 elementary school boys were examined. The incidence of external genital abnomalities was 27.8%. Certain anomalies were already surgically treated in 7.8% of boys. Phimosis wasfound in 66 patients (5,5%), which represents 26.6% of all abnomalities. DISCUSSION: In this study the incidence of undescended testis was 2.0%. Although it is similar to literature data, the fact that undescended testis was found in 25 boys older than 7 years (two of them 15 years old!) suggests that the primary health care is not satisfactory. The incidence of inguinal hernia and hydrocele varies according to different authors from 0.8-4.4% to 13.44%. In this study the incidence was 2.4%. Varicocele represents a developmental anomaly and the incidence is increasing with age. It is rare in boys up to 10 years of age, but the incidence of varicocele in boys aged 15 years (15.8%) reaches the level of incidence in adults (19.82%). The incidence of phimosis in this study was 5.5%. CONCLUSION: High incidence of external genital abnormalities in school aged boys suggests a need for further education of physicians in primary health care services as well as of parents.

[Ureteral triplication--a case report].

INTRODUCTION: Of all children born with congenital anomalies, 30-40% have urogenital abnormalities. Most of them are asymptomatic, but if any symptoms occur, they are usually symptoms of urinary infections. CASE REPORT: A four-year old girl was admitted because of recurrent urinary infections and in order to perform a thorough clinical examination. Clinical examination showed an asymmetrical gluteus and presence of a fibroma in the same region. Detailed radiologic examinations (ultrasonography, plain X-ray, excretory urography, voiding urethrocystography) revealed a triplicate ureter on the right side with a vesicoureteral reflux of the fifth grade on the same side. Intraoperatively, type III ureteric triplication according to Smith's classification was established. Ureteral remodeling and reimplantation was done. The postoperative course was good, and follow-up voiding urethrocystography showed absence of reflux. DISCUSSION: Ureteral triplication is a consequence of either development of three buds on the mesonephric duct, or development of two buds, one of which further divided into two parts. Most common anomalies associated with ureteral triplication are: ureteral duplication on the other side (37%), ectopy of the ureteric orifice (28%) and kidney dysplasia (8%). Vesicoureteral reflux is very common on affected or on both sides. Symptomatology is the same as in ureteral duplication--dominated by signs of urinary infections. CONCLUSION: Diagnosis of ureteral duplication requires detailed imaging. Treatment of symptomatic abnormalities should be individual, regardless of the applied treatment (conservative or operative).
