Paraphimosis, retention or destructive infection

A retracted foreskin trapped behind the glans with progressive oedema and dusky ischaemic change, inability to pass urine, rapidly spreading severe genital pain, crepitus, necrosis, fever or shock requires emergency urological and surgical assessment.

Action: Provide immediate analgesia and ABCDE care, attempt paraphimosis reduction only if trained and appropriate, start sepsis treatment for suspected necrotising or invasive infection and transfer urgently; do not delay for swabs or force an inflamed foreskin.

Synopsis

Assess glans and foreskin inflammation without diagnostic shortcuts, distinguish irritant, infective, inflammatory and neoplastic disease, use safe site-specific treatment, and escalate obstruction, paraphimosis and persistent lesions.

  • Balanitis is glans inflammation; balanoposthitis includes the foreskin. It describes a site, not an organism, so history and morphology must guide treatment.
  • Irritant disease is common after soap, overwashing, urine trapping, friction, incontinence or a new product and often improves with water-only care and emollient barrier.
  • Candida produces soreness with patchy erythema, small papules, subpreputial discharge or satellites, but recurrent disease should prompt review for diabetes, immune factors and alternative diagnoses.
  • Psoriasis is sharply demarcated and glazed with reduced scale on moist genital skin; nail, scalp, natal-cleft and extensor signs may reveal the diagnosis.
  • Lichen sclerosus causes pallor, fissures and a tightening scar ring and can produce pathological phimosis, urinary spraying and urethral disease.
  • Zoon balanitis creates a persistent shiny orange-red or red-brown patch in an older uncircumcised adult and requires exclusion of carcinoma and other mimics.
  • In children, a non-retractile foreskin is usually physiological and must not be forcibly retracted; inflammation, scarring, retention and recurrent infection change the pathway.
  • Offer a private inclusive sexual and medicine history, consent and a chaperone; examination or STI testing is based on symptoms and exposure, not identity or relationship status.
  • First-line irritant treatment is avoidance, gentle drying and bland emollient; use hydrocortisone 1% briefly for significant sterile inflammation or clotrimazole 1% for clinically likely Candida.
  • Biopsy a persistent indurated, velvety, eroded, ulcerated or bleeding lesion and review non-response rather than cycling through steroid, antifungal and antibiotic combinations.

Key red flags

Urinary retention, paraphimosis, dusky or necrotic tissue, severe pain out of proportion, systemic illness, rapidly spreading cellulitis, persistent induration, ulceration or bleeding, a fixed phimosis with scarring, or enlarged groin nodes requires urgent urological, surgical or cancer-pathway assessment.

Neoplastic focus

Persistent velvety red, pigmented, keratotic, eroded, ulcerated, indurated or bleeding tissue, especially with a node, requires urgent biopsy.

Investigation priorities

01
Consent-led genital and full-skin examinationFirst step

Define morphology and find foreskin, urethral, nodal or systemic clues.

Management branches

First-line irritant careRemove exposure and restore barrier

Diffuse mild inflammation follows soap, urine, friction or overwashing without ulcer, discharge, scar or systemic illness.

  1. Stop soap, wipes, fragrance and suspected lubricants, wash once daily with lukewarm water or bland emollient substitute and dry gently.
  2. Keep the foreskin in its natural position and use a small amount of bland emollient barrier; never force retraction in a child.
  3. For marked sterile inflammation use prescribed hydrocortisone 1% thinly once or twice daily for no more than seven days and review response.
First-line Candida careTreat likely yeast and its driver

Patchy soreness, discharge and peripheral papules support Candida, particularly after antibiotics or with diabetes.

  1. Apply clotrimazole 1% cream thinly twice daily for 7–14 days, continuing gentle drying and avoiding irritants.
  2. Test or manage diabetes and review immune, antibiotic and partner symptoms when disease is severe or recurrent; partner treatment is based on symptoms rather than automatic.
  3. Re-examine if there is no clear improvement within one week and reconsider psoriasis, contact allergy, lichen sclerosus, Zoon disease, STI and neoplasia.

Key medicines

Hydrocortisone 1% cream or ointmentApply a very thin layer once or twice daily to a mapped area of significant sterile irritant or eczematous inflammation for up to 7 days, then stop and reassess; use an ointment when preservative sensitivity or dryness favours it.Do not apply blindly to an undiagnosed ulcer, untreated HSV or a persistent focal lesion, and avoid prolonged unsupervised genital use. In children use only the age-appropriate prescribed product and never beneath forced foreskin occlusion.
Clotrimazole 1% creamApply thinly to clinically candidal glans and preputial skin twice daily for 7–14 days, following current product information and reviewing at one week if response is poor.Local burning or allergy can mimic worsening disease; cream can impair latex contraceptive effectiveness depending on formulation, so check the product information. Recurrent positive Candida does not exclude lichen sclerosus, psoriasis or diabetes.
