1/177. lung development in diamniotic twins discordant for complete urinary tract obstruction.

    OBJECTIVES: To investigate the effect of anhydramnios on the lung development of 1 twin in the presence of a normal amniotic fluid volume in its diamniotic co-twin. methods: Three sets of diamniotic twins, discordant for complete urinary tract obstruction and anhydramnios, were followed prospectively with regular ultrasound scans and after delivery. RESULTS: All 3 twins with complete urinary tract obstruction and anhydramnios died within 2 days after birth, with confirmed severe pulmonary hypoplasia. In every case the twin with a normal amount of surrounding amniotic fluid had a normal postnatal outcome. CONCLUSIONS: The observation that a normal amniotic fluid volume in one sac does not protect the anhydramniotic twin from pulmonary hypoplasia has important implications for the aetiology of the condition and for the possibility of therapeutic septostomy. These results are discussed in relation to previous human and animal studies. ( info)

2/177. Retroperitoneal iliac fossa abscess presenting as primary disease of the genitourinary tract.

    An iliac fossa abscess is a clinical entity that has not been described in the urologic literature. Three patients presenting with urologic symptoms were evaluated and found to have iliac fossa abscesses. It is important for the urologist to be aware of the existence, diagnosis and treatment of this entity. ( info)

3/177. Late complications of abdominal aortic grafting: urologic aspects.

    After an abdominal aortic operation late suture line failure with hemorrhage and false aneurysm formation can produce symptoms and/or findings of urologic disease. The urologist should be aware of the non-urologic implications in such instances. ( info)

4/177. Delayed presentation of a posttraumatic perirenal urinoma in a 6-year-old boy.

    A 6-year-old boy presented with a perirenal urinoma over the left flank about 3 months following trauma. Delayed presentation of a post-traumatic perirenal urinoma is rare in children, and percutaneous catheter drainage was effective in this case. ( info)

5/177. A case of nephrogenic diabetes insipidus caused by obstructive uropathy due to prostate cancer.

    Nephrogenic diabetes insipidus (DI) secondary to chronic urinary tract obstruction is a rare disease. The exact cause is unknown but it is likely that increased collecting duct pressures cause damage to the tubular epithelium, resulting in insensitivity to the action of arginine-vasopressin (AVP). A 77-year-old man complaining of polyuria and polydipsia was treated with alpha glucosidase inhibitor under the impression of polyuria due to diabetes mellitus. But his symptoms did not improve. water deprivation and AVP administration study revealed that the patient had nephrogenic DI. Urinary tract obstruction due to an enlarged prostate was suggested as a principal cause of nephrogenic DI. The patient underwent transurethral resection of the prostate and bilateral subcapsular orchiectomy. After surgery, the urine osmolarity was normalized and the patient became symptom-free. We report a case of nephrogenic DI due to obstructive uropathy which was cured by surgery eliminating obstruction. ( info)

6/177. Symptomatic paraurethral corpus spongiosum cyst in a male patient.

    The case of a 25-year-old man presenting with lower urinary tract symptoms who was found to have a noninflammatory posterior corpus spongiosum cyst is presented. The case was successfully managed by surgical excision and presents an uncommon cause of lower urinary tract dysfunction through irritation of the posterior urethra. ( info)

7/177. In utero repair of rectal atresia after complete resection of a sacrococcygeal teratoma.

    PURPOSE: A case of a fetus with a prenatally diagnosed sacrococcygeal teratoma that produced high-output cardiac failure, hydrops, rectal atresia, and urinary tract obstruction is presented. The unique prenatal surgical management along with the embryogenesis of tumor-related rectal atresia is discussed. CASE REPORT: A large fetal sacrococcygeal teratoma with a significant intrapelvic component was detected at routine ultrasound in a 35-year-old gravida 3 para 2. Fetal hydrops developed rapidly due to high-output cardiac failure from the vascular 'steal' by the growing tumor. The urinary tract was obstructed due to the intrapelvic tumors mass. At 27 weeks' gestation, the female fetus underwent hysterotomy, resection of the entire mass and urinary diversion via bilateral flank ureterostomies. The rectum was found to be completely atretic due to apparent encasement by the tumor. Pull-through anorectoplasty was carried out concurrently. At 30 weeks' gestation, the mother developed preterm labor and a 1.8-kg was delivered by cesarean section. The baby did very well for 3 days but had a cardiac arrest and died due to an atrial perforation by a transfemoral venous catheter. CONCLUSIONS: To our knowledge this is the first report of a complete prenatal resection of a sacrococcygeal teratoma with concomitant pull-through anorectoplasty for rectal atresia. ( info)

8/177. A giant urinoma in a neonate without obstructive uropathy.

    We report a neonate with a giant urinoma and renal failure. A 7-day-old boy had a giant abdominal mass of 6.5 cm x 8 cm in the right quadrant, gastroesophageal reflux, and renal failure caused by the compression from the mass. Radiological observations revealed a multiseptated cyst and neither kidney could be detected. To relieve these symptoms percutaneous drainage was performed. The contents of the fluid were similar to the patient's urine. The symptoms were improved by the drainage, and we found the left kidney to be absent and the right kidney small. Four prenatal ultrasound scans detected no cystic lesions in his abdomen. Neonatal urinomas are commonly complicated by obstructive uropathy, such as posterior urethral valves or ureteropelvic junction obstruction. These obstructive uropathies were ruled out by retrograde pyelography and voiding cystourethrography. A severely dilated upper pole of a double collecting system was also ruled out by intravenous pyelography and direct observation of the kidney during an open biopsy. The cause of the urinoma is still uncertain, but trauma during delivery and the dysplastic right kidney may be involved. ( info)

9/177. epidermolysis bullosa simplex (Dowling-Meara type) associated with pyloric atresia and congenital urologic abnormalities.

    We report a case of epidermolysis bullosa simplex, Dowling-Meara type (EBS-DM), which was associated with congenital pyloric atresia (PA) and various urologic abnormalities, a diagnosis confirmed by immunofluorescence mapping and electron microscopic findings. Immunofluorescent mapping showed the serum from a patient with bullous pemphigoid faintly binding to the floor of the blister, and monoclonal antibodies against type IV and VII collagens were also stained on the floor of the blister. Electron microscopy showed epidermolytic cleavage and prominent clumping of tonofilaments in the basal and suprabasal keratinocytes. An abdominal radiograph and barium swallow showed a complete obstruction at the pyloric channel level. The widespread bullae healed without any scar formation and the bullae formation was localized on the extremities after 3 months of age without any specific treatment. Multiple urologic abnormalities such as bilateral hydronephrosis, hydroureter and a distended bladder with trabeculation were observed at 12 months of age. Currently, with the patient at 4 years of age, bullae still appear on the hands and feet and nail shedding can be observed. The patient's father, a paternal uncle and a paternal aunt had had similar bullous eruptions in infancy, all of which had improved spontaneously by the age of one. ( info)

10/177. The egg-shell sign: a possible indicator of raised intrarenal pressure.

    prenatal diagnosis of pelvicalyceal dilatation has produced clinical material that we are continually reinterpreting with the help of improving ultrasound equipment. However, the ability to predict the outcome for any one patient with marked dilatation remains poor. We describe a new sign that may help identify those fetuses who have high intrarenal pressure and therefore justify more aggressive management, while obviating the need for intervention for those in whom it is not present. The egg-shell sign consists of a thin crescent of increased echogenicity over a distended calyx and, in this case, was documented to be associated with other features of raised intrarenal pressure.
