Purpose: To study what adult women with congenital adrenal hyperplasia (CAH) thought about the timing of genital surgery.

Methods: As part of a larger follow-up study performed between the years 2002-2005 there were questionnaires concerning genital surgery, type of surgery, their thoughts about timing of genital surgery and experience of information about surgery. Early surgery was defined as ≤4 years of age and late ≥10 years.

Objectives: There is a lack of studies on men's individual experiences of living with hypospadias. We aimed to explore the personal experiences of having hypospadias in relation to healthcare and surgery.

Subjects And Methods: Purposive sampling was used to include men (aged 18 and over) with hypospadias representing different phenotypes (from distal to proximal) and ages in order to maximise the variation and richness of our data.

Classic bladder exstrophy represents the most severe end of all human congenital anomalies of the kidney and urinary tract and is associated with bladder cancer susceptibility. Previous genetic studies identified one locus to be involved in classic bladder exstrophy, but were limited to a restrict number of cohort. Here we show the largest classic bladder exstrophy genome-wide association analysis to date where we identify eight genome-wide significant loci, seven of which are novel.

Bladder exstrophy is a rare congenital malformation leaving the urinary bladder open in the midline of the abdomen at birth. There is a clear genetic background with chromosome aberrations, but so far, no consistent findings apart from 22q11-duplications detected in about 2%-3% of all patients. Some genes are implicated like the LZTR1, ISL1, CELSR3, and the WNT3 genes, but most are not explained molecularly.

Congenital malformations often have a genetic background associated with a recurrence risk and may be part of a syndrome. Therefore, for children with a congenital malformation, the parents should be offered genetic counseling, and the child should also be offered the same when they reach adulthood. Hypospadias is a common malformation in boys that arises during genital development in weeks 8 to 16.

Introduction: Neurogenic lower urinary tract dysfunction (LUTD) has been reported in 20-50% of children with anorectal malformations (ARM). As neurogenic LUTD represents an inherent risk of renal deterioration and urinary tract infections, an early diagnosis is important. The gold standard for evaluating neurogenic LUTD involves invasive urodynamic testing but a useful addition should be an easy-to-perform, non-invasive method of screening.

Article Synopsis
  • Previous research shows that a specific phosphate transporter is present in the pronephric kidneys of developing zebrafish and is linked to cloacal exstrophy, a defect affecting urinary tract development.
  • The study used morpholino oligonucleotide knockdowns in zebrafish to observe that disruptions led to kidney malformations and voiding issues, resembling conditions seen in human cloacal exstrophy.
  • Additional genetic analysis in 690 individuals with bladder exstrophy-epispadias complex revealed new variants linked to the condition, but phosphate transport itself didn't seem to be affected, suggesting other cellular mechanisms, like apoptosis, could play a role in the disease's development.
