Abstract

Objectives: This study aimed to describe patterns of presentation, etiology, risk factors, management, and treatment outcomes of periurethral abscesses using a systematic review framework.

Materials and methods: After prospective registration on the PROSPERO database (CRD42020193063), a systematic review of Web of Science, Embase, PubMed, and Cochrane scientific databases was performed. Articles published between 1900 and 2021 were considered. Extracted data included symptoms, etiology, medical history, investigations, treatment, and outcomes. Collated data were analyzed using univariate methods.

Results: Sixty articles met the inclusion criteria reporting on 270 patients (211 male, 59 female) with periurethral abscess. The most common clinical features were pain (41.5%), pyuria (41.5%), dysuria (38.5%), urinary frequency (32.3%), fever (25%), and a palpable mass (23%). Predisposing risk factors included the presence of a sexually transmitted infection or urinary tract infection (55.0%), urethral strictures (39.6%), and recent urethral instrumentation (18.7%). Management approaches included open incision and drainage (64.3%), conservative management with antibiotics (29.8%), and minimally invasive techniques (needle aspiration, endoscopic drainage). Time trend analysis of etiology revealed a decreased incidence of infection (sexually transmitted infection/urinary tract infection, human immunodeficiency virus) and higher incidence of diabetes mellitus and periurethral bulking injections in recent years.

Conclusions: Periurethral abscesses may display a wide range of clinical features. Presentation, risk factors and underlying etiology vary with sex. The optimal management technique is guided by abscess size. Open incision and drainage combined with antibiotics continues to be the mainstay of management. However, minimally invasive techniques are gaining favor. To the authors' knowledge, this is the first systematic appraisal and management algorithm for periurethral abscess.
