Suburethral abscess: a complication of periurethral collagen injection therapy
1Department of Gynecology, Greater Baltimore Medical Center, Maryland 21204, USA. mmclenna@gbmc.org
Background:
Urinary tract infection after collagen injection is well documented. Other adverse reactions are rare.
Cases:
Three women experienced suburethral abscess after repeat periurethral injections. All patients received local skin preparation and postprocedural antibiotics. Symptoms failed to resolve with antibiotics. The first two patients presented after 5 weeks and 10 days with irritative voiding symptoms and a tender suburethral swelling. The first patient was treated with excision. Spontaneous rupture into the urethra occurred with the second. The third woman presented with acute urinary retention at 102 days. A large suburethral mass was drained successfully in the office.
Conclusion:
Suburethral abscess may be a delayed complication of periurethral collagen injections, not preventable by postprocedural antibiotics. Drainage is required.
