Post catheterization Fournier's gangrene involving the entire anterior urethra: case report.

INTRODUCTION AND IMPORTANCE

Fournier's gangrene is necrotizing fasciitis involving the penis, scrotum, or perineal region. This is to report necrosis of the entire anterior urethra by necrotizing infection even though the involvement of the urethra by Fournier's is a very rare presentation. A high index of suspicion is important for early intervention. The main Mode of treatment for Fournier's gangrene is debridement.

CASE PRESENTATION

This is a case report for a 58-year-old male patient who presented with penile and scrotal swelling after he was catheterized with NG tube for acute urinary retention. The physical finding shows swollen scrotum with ulcerated necrotic glans penis anteriorly. Laboratory result shows leukocytosis and urine analysis is positive for urinary tract infection and ultrasound shows bladder diverticula with normal prostate volume. He underwent debridement up to the level of membranous urethra and suprapubic catheterization was done. He was treated with antibiotics and wound care and finally, the wound closed. Post-operative cystourethrography was done 9 months later and we offered staged urethroplasty but he decided for permanent SPC.

DISCUSSION

Fournier's gangrene is a fatal rapidly spreading infection that occurs in the perineal area. Involvement of urethra by necrotizing infection following catheterization is very rare presentation and diagnosis is mostly clinical. Once it is diagnosed the management is surgical debridement.

CONCLUSION

Fournier's gangrene with urethral involvement is a very rare presentation and a high index of suspicion is important for early diagnosis and management. Following the standard procedural steps of catheterization is important to avoid this complication.
