INTRODUCTIONINTRODUCTION

3. DEVELOPMENT OF URETHRADEVELOPMENT OF URETHRA
•At 9 weeks the genital swellings (also called the labio-scrotal folds)
enlarge and rotate posteriorly. As they meet, they begin to fuse from
posterior to anterior.
• As the genital tubercle becomes longer, two sets of tissue folds develop
on its ventral surface on either side of a developing trough, the urethral
groove. The more medial endodermal folds will fuse in the ventral midline
to form the male urethra. The more lateral ectodermal folds will fuse over
the developing urethra to form the penile shaft skin and the prepuce. As
these two layers fuse from posterior to anterior, they leave behind a skin
line: the median raphe.
•By 13 weeks, the urethra is almost complete. A ring of ectoderm forms
just proximal to the developing glans penis. This skin advances over the
corona glandis and eventually covers the glans entirely as the prepuce or
foreskin.
4. EMBRYOLOGICAL EXPLAINATIONEMBRYOLOGICAL EXPLAINATION
Currently three main theories of penile
curvature are
1. Abnormal development of urethral plate
2. Abnormal fibrotic mesenchymal tissue
at the urethral meatus and penile shaft
3. Differential growth of dorsal and ventral
corporal tissue.

• Mild up to 30 degree
• Moderate 30-60 degree
• Severe > 60 degree
• Significant Chordee ---Curvature more
than 20-30 degree
• Bologna R A et al Urology 53:608-10 1999
9. CONTROVERSYCONTROVERSY
Young proposed that this entity was due
to congenital short urethra & he
suggested that it should be managed by
transection of hypo-plastic urethra &
reconstruction of urethra
Young HH Genital anomalies hermaphrodite and related adrenal
disease Wilkin & Wilkin 1937
10. CONTROVERSYCONTROVERSY
Devine & Horton in 1973 proposed that
chordee without hypospadias is due to
abnormal development of fascial layers of
penis & majority of these could be treated with
resection of fibrous tissue for chordee
correction, transection of urethra is rarely
required
Devine & Horton; Chordee without
Hypospadias J Urol 1973;110: 264
12. INDICATIONS OF SURGERYINDICATIONS OF SURGERY
• Most of the pediatrics urologists consider
chordee to be significant if it is more than
20-30 degree.
• A dorsal approach is preferred for mild
chordee up to 30 degree & conversely
chordee more than 50 degree in being
managed by ventral approach.
• Bologna R A et al Urology 53:608-10 1999
13. SURGERY AT WHAT AGESURGERY AT WHAT AGE
• Cendron and Melin proposed that it should correct after
puberty. They believed that the curvature would improve
spontaneously with the age and secondly it might disturb
the growth of the penis by altering the tunica of corpora
cavernosa.
• But others advocate that if diagnosed in childhood
correction should be at that time. Type III chordee
without hypospadias with mild to moderate chordee it is
logical to wait but in type II and type I should operated in
same age group as of hypospadias or whenever the
child presents to the hospital.

have raised the concern that dorsal
