November 10, 1988 / 37(44);679-680,685-686 Renal Agenesis Surveillance United States 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.

CAR: Anomalies - Renal Renal Agenesis Search for... Abdominal Cardiac Chromosome CNS ... Back to the CAR introduction page INTRODUCTION Renal agenesis anomaly may affect one or both kidneys and has an unknown aetiology. Bilateral renal agenesis (BRA) occurs sporadically but there is some evidence that genetic factors are involved and it is important to screen both parents and siblings. BRA can also occur as part of syndromes such as VATER and branchio-oto-renal syndrome but it is more commonly an isolated finding. BRA occurs more frequently in males (2:1) and is incompatible with life. Unilateral renal agenesis (URA) is much more common than BRA and is associated with some ear and ureteral anomalies. Top of the page Back to Renal ANTENATAL Renal agenesis may not be immediately apparent on ultrasound, but the bladder is never seen and from 16 weeks gestation it becomes apparent that there is reduced, or no liquor around the fetus. Doppler studies can be used to distinguish BRA from severe intrauterine growth retardation.

Renal Agenesis and Hypoplastic Lung Syndrome Vol 2. No. 10 Ande L. Karimu MD PhD. Resident Ob-Gyn Yale New Haven Hospital Renal agenesis and hypoplastic lung syndrome are congenital malformations of the neonates involving the kidneys and the lungs respectively i.e. the newborns are born with these disorders. The etiology of these malformations is probably multifactorial i.e. there are both inherited and environmental factors in the causation of the malformations. Oftentime both conditions co-exist as part of multiple congenital malformations. Renal Agenesis Renal agenesis is the complete absence of the kidney(s). The kidneys are the organs that filter the blood of waste products, eliminating them as urine. There are two kidneys in the human under normal circumstances. Absence of the kidney could be unilateral or bilateral. If it is unilateral, it means only one kidney is absent. However, if it is bilateral, it means both kidneys are absent. Unilateral absence of the kidneys is compatible with life whereas bilateral absence of the kidneys is incompatible with life. Development of the Kidneys The kidneys are parts of the urinary system. Other members of the system include the ureters, bladder and the urethra. The urinary system develops in close association with the genital organs.

Return to Risk Factor Menu BIRTH DEFECT RISK FACTOR SERIES: RENAL AGENESIS DESCRIPTION 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.

Associated persons: Edith Louise Potter Description: Potters Syndrome is the term used to describe the total absence or malformation of infant kidneys in combination with other congenital abnormalities, including Potter's facies, pulmonary hypoplasia, oligohydramnios, failure of foetal urinary production and skeletomuscular anomalies such as clubbing of the hands and feet and contractures. Oligohydramnios (deficiency of the amount of amniotic fluid) is the cause of failure of lung development and of limb compression in the foetus. Males are more commonly affected than females. The affected children are usually stillborn or die shortly after birth. Authors disagree whether inheritance is autosomal dominant recessive. Bibliography: H. Madisson:

Radiology-Pathology Teaching File Case# 1 Ten Month Old Boy with Pelvic Mass Clinical Information: Ten-month-old white male with constipation. A nontender mass is palpated on rectal exam. A. B. IVU: Intravenous urogram (B) demonstrates non-visualization of the left kidney and conpensatory hypertrophy of the right kidney. A mass in the left pelvis indents the bladder. Pelvic ultrasound: A transverse US image (A) reveals a mid to left sided retrovesicular simple cyst with displacement of the urinary bladder anteriorly and to the right. No solid component is seen. C. D. Pathologic specimen: The gross specimen (D) reveals a cystic mass of the left seminal vesicle which was resected with the cyst. Microscopic evaluation (C) revealed a simple cyst with the cyst wall consisting of smooth muscle and fibrous connective tissue with a small amount of stratified squamous epithelium. These findings are typical for a seminal vesicle cyst. Discussion: Seminal Vesicle Cyst with Ipsilateral Renal Agenesis Ipsilateral renal agenesis and cyst of the seminal vesicle are associated due to the common origin of the ureteral bud and seminal vesicle from the mesonephric (Wolffian duct). If an insult occurs approximately at the 12th gestational week, the embryogenesis of the kidney, ureter, seminal vesicle, and vas deferens can be altered.

The c-ret gene encodes a receptor tyrosine kinase that is expressed in the Wolffian duct and ureteric bud of the developing excretory system. Newborn mice homozygous for a mutation in c-ret displayed renal agenesis or severe hypodysplasia, suggesting a critical role for this gene in metanephric kidney development. To investigate the embryological basis of these defects, we characterized the early development of the excretory system in mutant homozygotes, and observed a range of defects in the formation

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. This disorder is more common in infants born of a parent who has a kidney malformation, particularly the absence of one kidney (unilateral renal agenesis).

Renal Agenesis Forum: The Urology Forum Topic: Kidney ID From To Post Q GI Joe (08-Apr-04) I've just discovered (thru CT Scan) I have congenital unilateral renal agenesis (absent kidney). I'm a military member (U.S.)and generally in good health. Will this condition disqualify me from military service? A Forum-M.D.-KYP (09-Apr-04) GI Joe I do not work for the US miltary so I do not know what the conditions are for disqualification. However, I can give information about the prognosis of the disorder. Renal agenesis refers to congenital absence of the kidney and ureter, which may be either unilateral or bilateral. Unilateral renal agenesis has been noted in 1/1000 autopsies. The prognosis for patients with one normal kidney is excellent, with a survival rate similar to that of age and sex-matched controls from United States life tables. However, proteinuria (i.e. protein in the urine), hypertension, and renal insufficiency appear to be more common later in life. Most pediatric urologists recommend that children with a solitary kidney avoid contact sports, although the risk of kidney loss resulting from trauma is less than 1 percent. I am not sure if that last statement would be relevent in active duty. You may want to address this issue with your personal physician.
