Introduction An epispadias is a rare type of malformation of the penis in which the urethra ends in an opening on the upper aspect (the dorsum) of the penis. It can also develop in females when the urethra develops too far anteriorly
Epidemioligy around 1/ 120,000 male 1/500,000 female births
Etiology It is a partial form of a spectrum of failures of abdominal and pelvic fusion in the first months of embryogenesis known as the exstrophy - epispadias complex. It occurs as a result of defective migration of the genital tubercle primordii to the cloacal membrane, and so malformation of the genital tubercle, at about the 5th week of gestation .
Associated anomalies The causes of epispadias are not known. It may occur because the pubic bone does not develop properly. Epispadias can occur with bladder exstrophy . In this rare birth defect, the bladder is inside out and sticks through the abdomen wall. Epispadias can also occur with other birth defects .
Presentation Most cases involve a small and bifid penis , which requires surgical closure soon after birth, often including a reconstruction of the urethra. Where it is part of a larger Exstrophy, not only the urethra but also the bladder ( bladder exstrophy ) or the entire perineum ( cloacal exstrophy ) are open and exposed on birth, requiring closure.
Presentation…………. Males usually have a short, wide penis with an abnormal curve . The urethra usually opens on the top or side of the penis instead of the tip. However, the urethra may be open along the whole length of the penis. Females have an abnormal clitoris and labia. The opening is usually between the clitoris and the labia, but it may be in the belly area. They may have trouble controlling urination (urinary incontinence ).
Examination Abnormal opening from the bladder neck to the area above the normal urethra opening Backward flow of urine into the kidney (reflux nephropathy) Urinary incontinence Urinary tract infections Widened pubic bone
Tests (for assos . anomaly) Blood test Intravenous pyelogram (IVP), a special x-ray of the kidneys, bladder, and ureters MRI and CT scans, depending on the condition Pelvic x-ray Ultrasound of the urinary system and genitals
Treatment The main treatment for isolated epispadias is a comprehensive surgical repair of the genito -urinary area usually during the first 7 years of life, including reconstruction of the urethra, closure of the penile shaft and mobilisation of the corpora .
modified Cantwell- Ransley approach The most popular and successful technique is known as the modified Cantwell- Ransley approach.
complete penile disassembly technique In recent decades however increasing success has been achieved with the complete penile disassembly technique despite its association with greater and more serious risk of damage
Complications Recurrence Sexual problems Incontinence UTI Infertility Psycho-social stress
