Renal hypodysplasia/aplasia 3
A severe, autosomal dominant disease encompassing a spectrum of kidney development defects. Clinical manifestations are highly variable and include bilateral or unilateral renal agenesis, renal aplasia, hypoplasia, (cystic) dysplasia, severe obstructive uropathy, and vesicoureteral reflux. Bilateral renal agenesis is almost invariably fatal in utero or in the perinatal period. Unilateral renal agenesis can lead to future health issues including end-stage renal disease.

Renal hypodysplasia/aplasia 2
A perinatally lethal renal disease encompassing a spectrum of kidney development defects, including renal agenesis, bilateral renal aplasia, hypoplasia, (cystic) dysplasia, and severe obstructive uropathy.
Coreceptor for GDNF, a neurotrophic factor that enhances survival and morphological differentiation of dopaminergic neurons and increases their high-affinity dopamine uptake (PubMed:10829012, PubMed:31535977). GDNF-binding leads to autophosphorylation and activation of the RET receptor (PubMed:31535977)

Renal hypodysplasia/aplasia 4
An autosomal recessive, severe congenital anomaly of the kidney and urinary tract characterized by bilateral renal agenesis, and severely reduced or absent amniotic fluid during pregnancy. Patients exhibit the Potter sequence, including flattened nose, ear anomalies, and receding chin. Some affected individuals have limb contractures and joint dislocations. Bilateral renal agenesis is almost invariably fatal in utero or in the perinatal period.
Integrin alpha-8/beta-1 functions in the genesis of kidney and probably of other organs by regulating the recruitment of mesenchymal cells into epithelial structures. It recognizes the sequence R-G-D in a wide array of ligands including TNC, FN1, SPP1 TGFB1, TGFB3 and VTN. NPNT is probably its functional ligand in kidney genesis. Neuronal receptor for TNC it mediates cell-cell interactions and regulates neurite outgrowth of sensory and motor neurons

Renal hypodysplasia/aplasia 1
A perinatally lethal renal disease encompassing a spectrum of kidney development defects, including renal agenesis, bilateral renal aplasia, hypoplasia, (cystic) dysplasia, and severe obstructive uropathy.
Ligand for members of the frizzled family of seven transmembrane receptors (Probable). Functions in the canonical Wnt/beta-catenin signaling pathway. Required for normal embryonic kidney development, and for normal development of the urogenital tract, including uterus and part of the oviduct and the upper vagina in females, and epididymis and vas deferens in males. Activates a signaling cascade in the metanephric mesenchyme that induces tubulogenesis. Acts upstream of WNT4 in the signaling pathw

Hirschsprung disease 1
A disorder of neural crest development characterized by absence of enteric ganglia along a variable length of the intestine. It is the most common cause of congenital intestinal obstruction. Early symptoms range from complete acute neonatal obstruction, characterized by vomiting, abdominal distention and failure to pass stool, to chronic constipation in the older child.

Long-Term Outcomes, Including Fetal and Neonatal Prognosis, of Renal Oligohydramnios: A Retrospective Study over 22 Years.
To assess the long-term outcome of renal oligohydramnios and risk factors for fetal, neonatal, and postneonatal death. This retrospective cohort study included fetuses with prenatally detected renal oligohydramnios between 2002 and 2023. Patients who were lost to follow-up were excluded. Fetal, neonatal, and long-term outcomes were evaluated, and their risk factors were analyzed. Of 131 fetuses with renal oligohydramnios, 46 (35%) underwent a termination of pregnancy, 11 (8%) had an intrauterine fetal death, 26 (20%) had a neonatal death, nine (7%) had a postneonatal death, and 39 (30%) survived. Logistic regression analyses showed that an earlier gestational age at onset (OR 1.16, 95% CI 1.01-1.37) was significantly associated with intrauterine fetal death; anhydramnios (OR 12.7, 95% CI 1.52-106.7) was significantly associated with neonatal death as a prenatal factor. Although neonatal survival rates for bilateral renal agenesis, bilateral multicystic dysplastic kidney (MCDK), and unilateral MCDK with contralateral renal agenesis were lower than for other kidney diseases, 1 case of bilateral renal agenesis and two of bilateral MCDK survived with fetal intervention. Kaplan-Meier overall survival rates were 57%, 55%, and 51% for 1, 3, and 5 years, respectively. In the Cox proportional hazards model, birth weight <2000 g (hazard ratio 7.33, 95% CI 1.48-36.1) and gastrointestinal comorbidity (hazard ratio 4.37, 95% CI 1.03-18.5) were significant risk factors for postneonatal death. Long-term survival following renal oligohydramnios is a feasible goal and its appropriate risk assessment is important.
Aphallia: A Very Rare Congenital Anomaly, With Associated Genitourinary And Ano-Rectal Malformation.
Aphallia or penile agenesis is very rare congenital anomaly of unknown cause occurring 1 in 30 million live births. Very little has been written in literature about aphallia. There is absent phallus and urethra may open abnormally in perineum or into rectum posing various surgical, social and psychological implications as the child grows. We are presenting 03 cases of aphallia with associated congenital anomalies such as unilateral renal agenesis, bilateral undescended testes, anorectal malformation and rectovasical fistula.
Multi-modality imaging review of congenital abnormalities of kidney and upper urinary tract.
Congenital abnormalities of the kidney and urinary tract (CAKUT) include a wide range of abnormalities ranging from asymptomatic ectopic kidneys to life threatening renal agenesis (bilateral). Many of them are detected in the antenatal or immediate postnatal with a significant proportion identified in the adult population with varying degree of severity. CAKUT can be classified on embryological basis in to abnormalities in the renal parenchymal development, aberrant embryonic migration and abnormalities of the collecting system. Renal parenchymal abnormalities include multi cystic dysplastic kidneys, renal hypoplasia, number (agenesis or supernumerary), shape and cystic renal diseases. Aberrant embryonic migration encompasses abnormal location and fusion anomalies. Collecting system abnormalities include duplex kidneys and Pelvi ureteric junction obstruction. Ultrasonography (US) is typically the first imaging performed as it is easily available, non-invasive and radiation free used both antenatally and postnatally. Computed tomography (CT) and magnetic resonance imaging (MRI) are useful to confirm the ultrasound detected abnormality, detection of complex malformations, demonstration of collecting system and vascular anatomy and more importantly for early detection of complications like renal calculi, infection and malignancies. As CAKUT are one of the leading causes of end stage renal disease, it is important for the radiologists to be familiar with the varying imaging appearances of CAKUT on US, CT and MRI, thereby helping in prompt diagnosis and optimal management.
