Duplication anomalies are quite common with ureteral duplication anomalies being the most frequent. Despite the relatively frequent incidence of a horseshoe kidney and duplication anomalies in any individual patient, the combination of horseshoe kidney and bilateral ureteric duplication is a very rare entity and very few cases have been reported to date. We present a case of a patient with a no...

BACKGROUND Although use of efficacious interventions, including antiretrovirals (ARVs), has dramatically reduced the rate of mother-to-child transmission of human immunodeficiency virus, the safety of in utero ARV exposure remains of concern. METHODS Data regarding 1112 infants enrolled in the International Maternal Pediatric Adolescent AIDS Clinical Trials Group protocol P1025 born between 2...

Congenital anomalies of the kidney and urinary tract are the major cause of end-stage renal disease in childhood. Children with a solitary functioning kidney form an important sub-group of congenital anomalies of the kidney and urinary tract patients, and a significant fraction of these children is at risk for progression to chronic kidney disease. However, challenges remain in distinguishing p...

Associated congenital anomalies are seen in 21% of retrocaval ureter patients; among them, associated contralateral renal agenesis is a very rare entity. We report one such case of right circumcaval ureter with left renal agenesis, diagnosed after febrile UTI. Surgical correction with uretero-ureterostomy was successful. In literature very few such cases are reported and only one case with rena...

INTRODUCTION The aims of this review are one, to consider that congenital urethral anomalies are not a simple disease entity in all patients. This is accomplished by reviewing the evidence for presence of posterior urethral valve subtypes and comorbidity of various unexplained clinical conditions in some children leading to chronic renal failure. The review's second aim is to describe the effec...

OBJECTIVE To compare the distribution of congenital anomalies within the VACTERL association (vertebral defects, anal atresia, cardiac, tracheoesophageal, renal, and limb abnormalities) between patients exposed to tumor necrosis factor-α (TNF-α) antagonist and the general population. METHODS Analysis for comparison of proportional differences to a previous publication between anomaly subgroup...

Congenital unilateral renal agenesis occurs in 0.93–1.8 per 1000 autopsies, and is usually diagnosed on an incidental imaging examination. Genital anomalies occur in 37–60% of females and 12% of males with congenital unilateral renal agenesis. Abnormalities in females include agenesis, duplication, rudimentary, unicornuate or bicornuate uterus, double or absent vagina, absent or hypoplastic ova...

To determine the incidence of silent renal anomalies in infants with isolated single umbilical artery (SUA), all infants with SUA and without other obvious congenital anomalies, identified over a six year period, were screened using renal ultrasonography. Over 35,000 placentas were examined. An isolated single umbilical artery was identified in 112 (0.32%). Nineteen infants had abnormal renal i...

BACKGROUND Occupational exposure to organic solvents during the 1st trimester of pregnancy has been associated with congenital anomalies. Organic solvents are also used in the home environments in paint products, but no study has investigated the effect of such exposure in a general population. METHODS We studied associations between residential exposure to paint fumes during the 1st trimeste...
