What is the appropriate management for a 17-year-old male with gradual penile shortening?

Gradual Penile Shortening in a 17-Year-Old Male

This adolescent requires urgent evaluation to differentiate between ischemic priapism sequelae, lichen sclerosus, congenital conditions, or other pathology, with immediate referral to pediatric urology for definitive diagnosis and management.

Initial Diagnostic Evaluation

The evaluation must focus on identifying the underlying cause through systematic assessment:

History Taking

• Duration and progression of shortening—acute versus gradual onset over months to years 1
• Associated pain with or without erection, which suggests active inflammatory or ischemic processes 1
• History of prolonged erections lasting >4 hours, which can cause corporal fibrosis and subsequent shortening 1
• Penile trauma during sexual activity or other injury 1
• Skin changes including whitish patches, scarring, or difficulty retracting foreskin suggesting lichen sclerosus 1
• Voiding symptoms such as weak stream or difficulty urinating indicating possible urethral involvement 1
• Previous surgeries including hypospadias repair or circumcision 1
• Baseline erectile function prior to onset of shortening 1

Physical Examination

• Measure penile length in both flaccid and erect states (using intracavernosal injection if needed for objective assessment) 1, 2
• Palpate for plaques or areas of induration along the penile shaft, particularly dorsally and laterally 1, 2
• Assess for curvature or deformity during erection 1, 2
• Examine the glans, meatus, and foreskin for signs of lichen sclerosus (whitish patches, scarring, meatal stenosis) 1
• Document skin changes including morphology, number, and location of any lesions 1, 3
• Evaluate for hourglass deformity or narrowing of the penile shaft 2, 4

Diagnostic Testing

Laboratory and Imaging Studies

• Corporal blood gas if there is any history of prolonged erections to assess for ischemic changes 1
• Penile duplex Doppler ultrasound to evaluate blood flow, identify plaques, and assess depth of any lesions 1
• MRI or ultrasound to evaluate depth of involvement if structural abnormality is suspected 1
• Complete blood count to screen for hematologic abnormalities including sickle cell disease 1
• Urinalysis and urine culture if urethral involvement is suspected 1

Common Etiologies in Adolescents

Priapism Sequelae

If there is history of prolonged erections >36 hours, the likelihood of permanent erectile dysfunction and corporal fibrosis with penile shortening is extremely high 1. Patients with priapism events >36 hours have low likelihood of erectile function recovery and develop significant corporal fibrosis leading to penile shortening 1. Even shorter episodes of 6+ hours can cause smooth muscle edema and atrophy 1.

Lichen Sclerosus

This inflammatory condition can affect the glans, foreskin, and urethra, causing scarring and contracture that leads to apparent shortening 1. In adolescents, lichen sclerosus may present with:

• Progressive meatal stenosis 1
• Urethral stricture disease extending to the mid-bulbar urethra 1
• Whitish plaques on the glans or prepuce 1

Peyronie's Disease (Rare in Adolescents)

While uncommon at age 17, acquired penile curvature with plaque formation can cause perceived shortening 1, 2. The typical presentation includes recent onset curvature with mild to moderate pain, though this usually affects men in their mid-50s 1.

Management Algorithm

Immediate Referral Indications

• Any history of priapism requires urgent urology evaluation 1
• Signs of lichen sclerosus with urethral involvement need specialized management 1
• Progressive symptoms with functional impairment warrant expedited assessment 1, 3

Condition-Specific Management

For Priapism-Related Shortening

If corporal fibrosis has already occurred from prior ischemic priapism, early penile prosthesis placement may be considered to preserve penile length and optimize future erectile function 1. Waiting allows progressive fibrosis and further shortening 1. Counseling should emphasize that erectile dysfunction is the most significant complication of prolonged ischemic priapism 1.

For Lichen Sclerosus

• Urethroplasty using non-genital tissue (buccal mucosa or bladder mucosa) is recommended, as genital skin grafts have 90% failure rates 1
• Avoid using penile skin flaps in reconstruction, as all genital skin may be affected by the disease process 1
• Staged reconstruction may be necessary for extensive disease 1

For Peyronie's Disease (if applicable)

• Distinguish between active disease (changing symptoms, pain) and stable disease (unchanged for ≥3 months) 1
• Active disease may improve spontaneously, particularly in younger patients with symptoms <6 months 1
• Surgical intervention is reserved for stable disease with adequate erectile function 1, 2

Critical Pitfalls to Avoid

• Do not delay evaluation assuming this is normal adolescent development—progressive penile shortening is never normal 1
• Do not perform repeated endoscopic procedures if lichen sclerosus is present, as this worsens outcomes for subsequent reconstruction 1
• Do not use genital skin for any reconstructive procedures in lichen sclerosus patients 1
• Do not dismiss psychological impact—penile concerns cause significant distress, depressive symptoms, and relationship difficulties even in adolescents 1
• Consider referral to pediatric urology for complex or concerning cases rather than attempting management in general practice 3

Counseling Points

• Prognosis depends entirely on the underlying cause and duration of the condition 1
• Surgical options exist for most causes of penile shortening, including lengthening procedures, grafting techniques, and prosthesis placement 2, 5, 6, 4, 7
• Early intervention generally provides better outcomes than delayed treatment, particularly for ischemic conditions 1
• Psychological support should be offered given the significant emotional impact of penile concerns in adolescents 1
