Treatment of a complete lower urinary tract obstruction secondary to an expandable foam sealant

We present a unique case of an iatrogenic complete lower urinary tract obstruction with an expandable foam sealant. A 41-year-old man presented in urinary retention 36 hours after self-injecting his urethra with the foam sealant, which could be palpated throughout his entire urethra. The sealant was removed from the distal urethra in numerous fragments with a hemostat and cystoscopically. A perfect mold of the bladder and prostatic urethra were removed by suprapubic cystotomy. Cystoscopy 2 months later demonstrated a mild bulbar urethral stricture, but normal bladder mucosa. The cystoscopy at 6 months was normal.
