Epispadias
|
Generally associated with bladder exstrophy (see this term) that combines a abnormal closure of the pubic symphysis, a significant defect of the abdominal wall and severe abnormalities of the terminal portion of the urinary and genital tract. There is a male prevalence.
Clinical presentation:
- boy: the urethra opens at the upper face of the penis with an external urethral orifice located at the proximal part of it; urinary incontinence
- girl: there is a wide open urethral canal between the 2 hemiclitoris; narrow, horizontalized vagina; urinary incontinence.
The epispadias associated with bladder exstrophy is repaired either during a third stage of the exstrophy reconstruction (in childhood) or in the neonatal period if reconstruction is done in one stage.
The two types of approaches currently used are:
1) 3-step reconstruction:
- 1st stage: in the neonatal period, closure of the abdominal wall, the bladder and the pubic symphysis (iliac osteotomies);
- 2nd stage: reconstruction of the urethra and anti-reflux surgery by the endovesical route (Cohen's intervention most often);
- 3rd stage: repair of the epispadias; sometimes associated with bladder augmentation surgery.
2) Reconstruction in a single procedure: it is a very long neonatal and hemorrhagic operation (6 hours) aiming to quickly create a functional bladder.
It includes 5 steps:
- closure of the bladder and the bladder neck,
- repair of the epispadias,
- reconstruction of the pelvis and the pubic symphysis with bilateral iliac osteotomies (hemorrhagic stage),
- bilateral inguinal herniorraphia,
- closure of the abdominal wall with a muscle and a skin layer
In girls, the stage of epispadias repair consists in a clitoroplasty and there is an additional surgical step: a vaginoplasty.
Isolated epispadias is corrected in infancy.
Primary prevention of latex allergy is necessary from the first procedure.
Anesthetic implications:
check renal function; indication of a lumbar epidural block for perioperative analgesia.
