[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.

[Constipation--a common problem in childhood].

INTRODUCTION: Constipation in children is defined as the infrequent and difficult passage of hard stool, not necessarily associated with in-frequent stools. All healthy newborns have their first stool within the first 24 to 48 hours after birth. Intestinal transit time increases with age, therapy decreasing the frequency of stooling. ANATOMY AND PHYSIOLOGY OF ANUS AND RECTUM: Acquisition of fecal continence requires: normal internal and external anal sphincters, puborectal muscle as well as intact sensory input from both the rectal vault and anal canal. ETIOLOGY AND DIFFERENTIAL DIAGNOSIS: During the first year of life, failure to have bowel movement every other day warrants evaluation. During infancy, constipation is usually due to dietary manipulations, malnutrition or some other functional abnormalities. Anatomic causes are found only in 5% of patients. DIAGNOSIS AND THERAPY: Diagnosis relies on history and physical examination. Digital rectal examination usually reveals a shorter anal canal with decreased sphincter tone. The rectal ampulla is dilated and filled with stool. Anorectal manometry is helpful in differentiating functional constipation from aganglionosis or other neurologic problems. Treatment varies depending on the underlying cause. Bowel retraining, aimed at establishing regular daily bowel movement, is of utmost importance in children. The response to treatment is usually dramatic. CONCLUSION: Constipation in children causes anxiety in the family and successful treatment requires persistent reassurance and repeted reevaluation.

[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).
