Sterile abscess formation following periurethral injections with synthetic polycaprolactone microspheres suspended in a carboxymethylcellulose gel (Urolon®): A case report

Abstract

Periurethral injection of bulking agents is a technique used to treat urinary incontinence due to stress incontinence, preferably caused by intrinsic sphincter deficiency. The variety of the nature of existing bulking agents leads to different success rates and complications. This case report describes the formation of pseudo-abscesses after periurethral injections with a bioresorbable implant consisting of synthetic polycaprolactone microspheres suspended in a carboxymethylcellulose gel carrier.
