An Investigation of the Male Genitourinary Abscess Originated from Urinary Tract in a Tertiary Hospital, Shanghai, China, from 2004 to 2019
Abstract
Background: Male genitourinary abscess is one of the serious complications of urinary tract infections (UTIs). There were few researches on the clinical and pathogenic characteristics of male genitourinary abscess. Patients and Methods: A retrospective observational study was conducted between January 2004 and April 2019. Male patients with genitourinary abscess originated from urinary tract, including sites of scrotum, testis, epididymis, spermatic cord, and prostate, were enrolled. Clinical and microbial records were collected and analyzed, and antimicrobial susceptibility testings were performed according to CLSI standard. Whole-genome sequencing was applied to detect the β-lactamase genes and virulence genes, as well as to determine the multilocus-sequence typing (MLST) of the collected Klebsiella pneumoniae ( K. pneumoniae ) isolates. Results: A total of 22 male patients were included. The main clinical symptoms were fever (86.4%), scrotal swelling (68.2%), local skin warmth (59.1%) and ulceration (45.5%). Urinary irritation was often presented in prostate involved abscess. Ultrasound features had a 94.7% positive rate. Surgical treatment, including abscess drainage, was helpful to the prognosis. No matter where the specimens obtained from, including blood, urine or pus, multidrug-resistant K. pneumoniae was the dominant (11 cases, 50.0%) microorganism in positive cultures. Nine of eleven K. pneumoniae isolates had been preserved and recovered. As for MLST typing, all…
