Emphysematous sloughed floating ball after prostate water vaporization Rezum: A case report

BACKGROUND Rezum (TM) water vapor therapy is a new minimally invasive endoscopic technology for the management and treatment of benign prostatic hyperplasia. CASE SUMMARY A 63-year-old male presented to our department with severe dysuria, frequency, urgency, and interrupted stream 2 mo after receiving Rezum (TM) therapy. The symptoms were caused by a retained floating emphysematous necrotic sloughed tissue. We also discovered a persistent bacterial infection that was resistant to parenteral antimicrobial therapy. The treatment of the patient included surgical removal of the necrotic tissue. CONCLUSION Despite the good safety profile and minimal adverse events related to Rezum (TM) therapy, major complications can still occur.
