2/238. Does every patient with prenatal hydronephrosis need voiding cystourethrography?

    PURPOSE: Prenatal ultrasound has allowed early identification of urinary tract abnormalities that may require urological followup or early intervention. While all children with prenatal hydronephrosis should undergo ultrasound within the first few weeks of life, we believe that there is a subset of postnatal hydronephrosis for which voiding cystourethrography can be avoided if careful observation is continued. MATERIALS AND methods: For 5 years 175 infants with a history of prenatal hydronephrosis were evaluated by ultrasound. Of 60 infants with less than Society for Fetal urology grade II unilateral or bilateral hydronephrosis 44 underwent voiding cystourethrography as part of the early evaluation and 16 were observed without voiding cystourethrography. Four infants for whom we would routinely obtain voiding cystourethrography were excluded from study due to severe prenatal hydronephrosis, renal duplication, hydroureter, ipsilateral small or echogenic kidney and grade II or higher hydronephrosis. RESULTS: Voiding cystourethrography was positive in 6 of the 40 infants (15%) with less than grade II hydronephrosis. Of these cases 3 had grade III or higher vesicoureteral reflux and 1 with high grade reflux required reimplantation. None of the 16 patients followed without voiding cystourethrography has required further evaluation or intervention. In all patients with negative or no voiding cystourethrography parenchyma was preserved and hydronephrosis stabilized or resolved. CONCLUSIONS: Prenatal and postnatal ultrasound in infants should be used to guide further urological evaluation. Among infants with less than grade II hydronephrosis postnatally 15% had reflux on voiding cystourethrography, which is significantly higher than that reported among normal children (approximately 1%). However, none of the 16 infants observed without voiding cystourethrography on short-term antibiotic prophylaxis had deleterious renal events with 6 months to 4.5 years of followup. Therefore, we question the actual significance of the reflux detected in the first cohort of infants. Voiding cystourethrography can provide a definitive answer. However, we also believe that it is not absolutely mandatory based on the outcome in the observed group. With careful counseling and followup most patients with less than grade II hydronephrosis can be observed without urological sequela.

3/238. citrobacter diversus urosepsis and cerebral abscess in a child with antenatal hydronephrosis.

    One percent of all pregnancies are found to have an antenatal abnormality; of these, 20% involve the genitourinary system. Today, controversy still exists regarding the postnatal management of some antenatal abnormalities detected by ultrasound. We present a case in which antenatal hydronephrosis initially detected by ultrasound appeared to resolve in utero. Postnatally, the child developed citrobacter diversus urosepsis, meningitis, and cerebral abscess. Voiding cystourethrogram obtained after resolution of sepsis revealed grade IV reflux. This case underscores the importance of a full postnatal evaluation for all children with antenatal hydronephrosis and alerts clinicians to a virulent pathogen not commonly associated with urinary tract infection.

4/238. Application of continent retubularized ileal stoma (Monti procedure) to an ileocecal pouch.

    We describe the application of a retubularized ileal stoma (Monti procedure) to an ileocecal pouch in a patient with a spinal cord injury who required a continent urinary diversion. When constructing a continent diversion with an ileocecal pouch, this technique seems a good choice, with significant advantages over the other alternatives.

5/238. urethral obstruction and bilateral ureteral hydronephroses secondary to fecal impaction.

    We present a case report of the first adult woman reported to suffer from both urethral obstruction and bilateral ureteral hydronephroses secondary to fecal impaction. The work-up suggested that hypothyroidism might be the cause for fecal impaction. urinary tract obstruction caused by hypothyroidism-induced fecal impaction has never been reported. fecal impaction should be considered as one of the causes for urinary tract obstruction.

6/238. 49,XXXXY syndrome with hydronephrosis caused by intravesical ureterocele.

    A 1-month-old boy was referred to our hospital with right hydronephrosis. Excretory urography showed poor visualization of the right kidney and a filling defect in the bladder. Chromosomal analysis of peripheral blood revealed a karyotype of 49,XXXXY, and a diagnosis of 49,XXXXY Klinefelter s syndrome associated with hydronephrosis caused by intravesical ureterocele was made. 49,XXXXY Klinefelter s syndrome with anomalies of the urinary tract is extremely rare, and only 2 cases have been reported so far.

7/238. Zonisamide - induced urinary lithiasis in patients with intractable epilepsy.

    We report here three patients with intractable epilepsy who developed urinary lithiasis during zonisamide (ZNS) treatment. abdominal pain due to left-sided hydronephrosis was the initial symptom in the first patient, and it was resolved after the excretion of a stone. The second patient, who had no specific symptoms, was found to have a thick sludge of calcium phosphate in the bladder when he suffered from aspiration pneumonia and dehydration. The third patient, who had a history of recurrent urinary obstruction, was also found to have a thick sludge of calcium oxalate in the bladder. The urinalysis of the three patients revealed alkaline urine and hypercalciuria. Although their urinary lithiasis was resolved by discontinuation of ZNS and supportive therapy, routine examination of urine parameters such as pH and sediments, and daily urine-output checks are thought to be necessary during treatment with ZNS, especially for patients who are bedridden for a long time and receive multiple antiepileptic drugs.

8/238. Functional urinary tract obstruction developing in fetuses with isolated gastroschisis.

    OBJECTIVE: To evaluate the frequency and natural history of urinary tract abnormalities developing in fetuses presenting with initially isolated gastroschisis. methods: Serial ultrasounds were performed prospectively on fetuses identified by our prenatal diagnosis program as having a gastroschisis. When abnormalities in the urinary tract were identified prenatally, newborns were evaluated by a pediatric urologist. RESULTS: Over a 1-year period four out of 12 fetuses with gastroschisis developed deformations of the urinary tract. In three fetuses the bladder herniated through the abdominal wall defect. Two also had upper tract dilatation. A fourth fetus developed bilateral hydronephrosis with a normally situated bladder. Once the gastroschisis was repaired none of the newborns had evidence of structural obstruction of the urinary tract, however, hydronephrosis with or without reflux persisted for several months. CONCLUSIONS: Deformations of the fetal urinary tract can develop secondary to gastroschisis. They do not appear to represent separate malformations and evaluation with fetal karyotyping may not be indicated. When hydronephrosis is present ongoing urologic evaluation of the neonate is indicated.

9/238. Inferior vena cava compression due to massive hydronephrosis from bladder outlet obstruction.

    A 71-year-old man presented with acute urinary retention due to benign prostatic hyperplasia and was found to have computed tomography-documented mechanical obstruction of the inferior vena cava (IVC) due to massive hydronephrosis. Obstruction of IVC flow promptly resolved after bladder decompression.

10/238. A case of prune belly syndrome.

    The prune belly syndrome was first described in 1839 by Frolich. Till now about 300 cases have been reported in literature. The complete form of the syndrome is presented by a classic triad that is seen only in boys and is incompatible with life. The etiology of the syndrome is uncertain. Genetic factors, intrauterine infections, adverse mechanical factors have been implicated. The prenatal diagnosis relies on the ultrasonographic findings of oligohydramnion, renal anomalies, and non-immune fetal hydropsy. The present case concerns a newborn of male sex suffering from the most severe and rare form of the syndrome. The child died 5 minutes after his birth. The pathological examination found the patient devoid of striated muscles anterior abdominal wall, urethral atresia, hyperthrophy of the urinary bladder, bilateral hydroureter and hydronephrosis and coinciding cryptorchidism. The case indicates the PBS as one of the possible reasons for non-immune fetal hydropsy.
