CHORDEE

Jennifer A. Hagerty, DO

BASICS

DESCRIPTION

• Chordee is ventral penile curvature that occurs with or without hypospadias:

– Epispadias can occur with dorsal curvature

– Lateral curvature also can occur with or without hypospadias

EPIDEMIOLOGY

Incidence

The incidence of chordee is unknown

Prevalence

• 44% of fetuses through the 2nd trimester suggesting chordee is a normal part of development (1)[A]

• Chordee occurs without hypospadias in 4–10% of cases of congenital chordee (2)[C]

• Hypospadias occurs in 1 of 250 live births (3)[A]

– Chordee is identified in 1/3 of these patients (3)[A]

RISK FACTORS

• Congenital

• Prior penile surgery

• Trauma

Genetics

• Found in syndromes associated with hypospadias

• Chromosomal abnormalities found in 22% of individuals with severe hypospadias associated with undescended testicles

• 14% of hypospadias in siblings

• 8% incidence in offspring

PATHOPHYSIOLOGY

• Chordee could be considered an arrest of normal embryologic development

• Different proposed etiologies for chordee without hypospadias (2,4):

– Class I: Results when corpus spongiosum, dartos, and Buck fasciae are deficient over the involved portion of the urethra; urethra is just below the skin, and the dense fibrous tissue beneath the urethra is responsible for the chordee.

– Class II: Spongiosum is normal while the dartos and Buck fasciae are dysgenetic.

– Class III: Only the dartos fascia is deficient.

– Class IV: Corporeal disproportion.

ASSOCIATED CONDITIONS

• Hypospadias

• Epispadias

• Penile torsion

• Cryptorchidism

• Disorders of sexual development

GENERAL PREVENTION

None known

DIAGNOSIS

HISTORY

• Visualized curvature of the penis with an erection

• Presence of hypospadias

PHYSICAL EXAM

• Observe the individual’s erection if possible

• Possible coexisting findings:

– Hypospadias or epispadias

– Incomplete foreskin ventrally

– Penoscrotal webbing

– Penile torsion

– Hypoplasia of the ventral shaft skin

– Cryptorchidism

DIAGNOSTIC TESTS & INTERPRETATION

Lab

• Routine lab testing not typically indicated

• Chromosomal testing and/or biochemical testing in the individual with a suspected syndrome or disorder of sexual differentiation

Imaging

• Renal and bladder ultrasound routinely recommended only in individuals with:

– Severe hypospadias

– Hypospadias associated with other organ system anomalies

Diagnostic Procedures/Surgery

• Intraoperative artificial erection test at the time of repair

– Infusion of injectable saline into the corpora with a tourniquet at the base of the penis

Pathologic Findings

N/A

DIFFERENTIAL DIAGNOSIS

• Disorder of sex development

• Epispadias

• Hypospadias

• Normal penile variant

• Penile torsion

TREATMENT

GENERAL MEASURES

Chordee repair is the standard approach

MEDICATION

First Line

None usually indicated specifically for chordee

Second Line

N/A

SURGERY/OTHER PROCEDURES

• Specific surgery dependant on the associated conditions and the severity of the curvature

• Performed typically after 6 mo of age

• General points:

– Following penile skin release, induce artificial erection. This should be repeated to confirm correction.

– Chordee without hypospadias often can be corrected by penile degloving with excision of the fibrous tissue superficial to Buck fascia.

– More moderate chordee requires simple plication and/or excision of ellipses from the site of maximum curvature.

– In the most severe cases, often associated with hypospadias the urethra may be foreshortened and need to be transected.

– Chordee secondary to corporeal disproportion involves incising the tunica albuginea on the ventral surface of the penis, transversely over the point of maximal curvature; than covering the defect with either a free dermal, tunica vaginalis or single ply small intestinal submucosal (SIS) graft.

– It is critical to identify and preserve the neurovascular bundles during dissection and plication.

– Skin flaps may be required for penile skin coverage after correction of the chordee.

ONGOING CARE

PROGNOSIS

• Excellent prognosis postoperatively with a low complication rate

• There may be progression of chordee after puberty (5)[C]

COMPLICATIONS

Recurrence of chordee

FOLLOW-UP

Patient Monitoring

• Postoperative checkup within several weeks after surgery

• Consider follow-up after puberty
