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.
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.
Stop soap, wipes, fragrance and suspected lubricants, wash once daily with lukewarm water or bland emollient substitute and dry gently.
Keep the foreskin in its natural position and use a small amount of bland emollient barrier; never force retraction in a child.
First-line Candida careTreat likely yeast and its driver
Patchy soreness, discharge and peripheral papules support Candida, particularly after antibiotics or with diabetes.
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.
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.
