Emergency and Acute Medicine – Paraphimosis
Paraphimosis is a urologic emergency defined by entrapment of the retracted foreskin proximal to the glans penis. This entrapment leads to progressive lymphatic congestion and venous obstruction, which can ultimately compromise arterial blood flow to the glans. If not promptly recognized and treated, paraphimosis may result in ischemia, necrosis, and permanent penile injury.
The condition most commonly occurs when the foreskin is retracted and not returned to its normal position. Predisposing factors include phimosis, inflammation, trauma, and sexual inexperience, particularly in individuals unaware of the need to reduce the foreskin after intercourse. Paraphimosis is frequently iatrogenic, occurring after physical examination, urinary catheterization, cystoscopy, or genital hygiene when the foreskin is left retracted.
Patients typically present with penile pain, a visibly retracted foreskin, and a swollen, edematous glans. The glans may appear erythematous, dusky, or cyanotic as venous congestion progresses. Local cellulitis may be present, and in advanced or untreated cases, necrosis of the glans can develop. Physical examination should include careful inspection of the entire penis to exclude constricting foreign bodies or bands, such as hair tourniquets, wire, or string, which can mimic paraphimosis.
The diagnosis of paraphimosis is clinical and should be made based on history and physical examination alone. Treatment must not be delayed for laboratory or imaging studies. Imaging is generally unnecessary unless a foreign body is suspected, in which case radiographs may be obtained after restoration of adequate perfusion.
Initial management focuses on rapid reduction of edema and prompt return of the foreskin to its normal position to restore blood flow. Pain control is essential and may require local anesthesia, a penile nerve block, systemic analgesia, or conscious sedation, especially in children. Ice packs may be applied to the glans to reduce swelling while preparations for reduction are made. Manual reduction is the first-line treatment and involves circumferential compression of the edematous glans while simultaneously applying traction to advance the foreskin distally over the glans.
If manual reduction is unsuccessful, additional techniques may be employed to reduce edema. These include the multiple puncture technique, in which small-gauge needle punctures are made in the swollen foreskin to allow expression of edema fluid, followed by another attempt at manual reduction. Osmotic methods, such as application of gauze soaked in 50% dextrose, may also help decrease edema if immediate reduction is delayed. When noninvasive methods fail, a dorsal slit of the foreskin may be required to release the constricting ring. In some cases, suturing may be necessary after reduction if the incision is extensive.
Antibiotics are generally not required unless there is associated cellulitis or balanoposthitis. Once reduction is successful and symptoms resolve, most patients can be discharged with close urologic follow-up. Admission is indicated for patients with penile necrosis, severe infection, or inability to achieve reduction. Urologic consultation is recommended in all cases, and circumcision may be considered to prevent recurrence, although this remains a topic of clinical debate.
Patient education is essential to prevent recurrence. Patients should be instructed on proper foreskin hygiene and the importance of returning the foreskin to its normal position after retraction for cleaning, sexual activity, or medical procedures. Early recognition and prompt management are key to preventing serious complications of paraphimosis.
