UpToDate Prenatal Diagnosis Of Renal Agenesis INTRODUCTION renal agenesis refers to congenital absence of the kidney and Inactivation of the RET protooncogene, which leads to renal agenesis or http://patients.uptodate.com/topic.asp?file=pregcomp/13063
Extractions: NORMAL SONOGRAPHIC ANATOMY The kidneys and adrenals, located below the level of the stomach, on either side and anterior to the spine, are visible by ultrasonography from as early as 9 weeks of gestation and in all cases from 12 weeks. The renal echogenicity is high at 9 weeks but decreases with gestation; the adrenals appear as translucent structures with an echodense cortex. 5 mm at 1519 weeks, 6 mm at 2029 weeks and 8 mm at 3040 weeks. The normal ureters are rarely seen in the absence of distal obstruction or reflux. The fetal bladder can be visualized from the first trimester (in about 80% of fetuses at 11 weeks and more than 90% by 13 weeks); changes in volume over time help to differentiate it from other cystic pelvic structures. RENAL AGENESIS Renal agenesis is the consequence of failure of differentiation of the metanephric blastema during the 2528th day of development and both ureters and kidneys and renal arteries are absent.
Renal Agenesis Surveillance -- United States During 19701978, this code was classified only as renal agenesisthe congenital Newborns with bilateral renal agenesis have low-set, floppy ears, http://www.cdc.gov/mmwr/preview/mmwrhtml/00001301.htm
Extractions: Newborns with bilateral renal agenesis have low-set, floppy ears, a broad, flat nose, and underdeveloped lungs. These newborns often die of respiratory failure within a few hours of birth. Lungs of infants with at least one functional kidney usually develop normally; thus, unilateral renal agenesis is often not detected during the perinatal period. The cases in this evaluation included 1404 newborns with an ICD code of 753.0. Participating hospitals provided copies of the discharge summary, pathology reports, and x-ray reports. For 966 (69%) of the infants, hospital reports supported the diagnosis of renal agenesis or renal dysgenesis. Of these, 468 (48%) had bilateral renal agenesis, 105 (11%) had one agenic and one dysgenic kidney, 229 (24%) had bilateral renal dysgenesis, 136 (14%) had unilateral renal agenesis, and 28 (3%) had unilateral renal dysgenesis. For the 14-year period 1970-1983, clinical reports of anomalies coded to 753.0 showed the following trends: 1) the annual frequency of bilateral renal agenesis varied considerably but appeared to increase slowly; 2) the prevalence at birth of one agenic and one dysgenic kidney remained constant; 3) the annual frequency of unilateral renal agenesis varied, although the number of infants with this diagnosis was small, and most cases were found incidentally during autopsy; and 4) the incidence of bilateral renal dysgenesis increased 10-fold from 0.03 per 10,000 births in 1970 to 0.33 per 10,000 births in 1983.

Extractions: bilateral renal agenesis Potter's Syndrome is a rare condition occurring in sporadic and autosomally recessive forms. It is incompatible with life. The key problem is bilateral renal agenesis. Potter found this in 1 in 4000 births, especially males. Renal agenesis causes oligohydramnios. The lack of amniotic fluid to cushion the fetus results in the characteristic squashed facies and other features of Potter's syndrome.

PubMed Citation To the Editor: Germ-line mutations in the RET proto-oncogene are associated with various disease phenotypes including familial medullary thyroid carcinoma and Hirschsprung's disease. Studies have suggested an involvement of RET in the development of the mammalian kidney. The RET proto-oncogene encodes a receptor tyrosine kinase that is involved in inductive interactions between the epithelium of the ureteric bud and metanephric mesenchyme, leading to the differentiation of a functional kidney. Although mice lacking functional ret may have renal agenesis or dysgenesis, no clinically relevant renal abnormalities have been reported in patients with familial medullary thyroid carcinoma who Full Text of this Article References

Congenital anomalies occur in the kidney more frequently than in any other organ of the body. It has been stated that congenital anomalies are responsible for about 40% of all pathologic lesions involving the kidneys. Although developmental errors of form, position and structure are more prone to cause disease than anomalies of number, the condition of renal agenesis remains one of the most interesting and diagnostically important of all urologic entities. The reports in the literature of cases of

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

Extractions: Find Services ... Buscar Renal agenesis is the absence of one or both of the kidneys. Bilateral renal agenesis is invariably fatal. Unilateral renal agenesis may be asymptomatic and is often incidentally diagnosed by abdominal ultrasound or computed tomography (CT) scan secondary to another condition. In infants with unilateral renal agenesis, the remaining kidney may be enlarged, and there is increased risk of problems with the remaining kidney. Renal agenesis has been associated with such chromosomal abnormalities as trisomy 21, trisomy 22, trisomy 7, trisomy 10, 45,X mosaicism, and 22q11 microdeletion (Bianchi et al., 2000). Fetal deaths have been reported to account for 10-33% of cases of renal agenesis (Bianchi et al., 2000; Riley et al., 1998; Cunniff et al., 1994). Renal agenesis can be prenatally detected by ultrasound (Bianchi et al., 2000). Thus, in regions where elective termination is allowed, prenatal diagnosis and elective termination may reduce the birth prevalence of renal agenesis (Riley et al., 1998; Sipek et al., 1997; Chi et al., 1995; Papp et al., 1995; Stoll et al., 1995a; Stoll et al., 1995b; Cunniff et al., 1994; Julian-Reynier et al., 1994; Stoll et al., 1992). The metanephric buds begin to develop into kidneys in the fifth week of gestation. If the metanephric buds fail to develop, renal agenesis results.
Extractions: It is possible that the main title of the report Renal Agenesis, Bilateral is not the name you expected. Please check the synonyms listing to find the alternate name(s) and disorder subdivision(s) covered by this report. Bilateral Renal Agenesis is the absence of both kidneys at birth. It is a genetic disorder characterized by a failure of the kidneys to develop in a fetus. This absence of kidneys causes a deficiency of amniotic fluid (Oligohydramnios) in a pregnant woman. Normally, the amniotic fluid acts as a cushion for the developing fetus. When there is an insufficient amount of this fluid, compression of the fetus may occur resulting in further malformations of the baby.
