Abstract PDF Supplementary Material PubReader ePub: Purpose
Fournier gangrene (FG) is a rare but life-threatening necrotizing infection requiring prompt recognition and intervention. This multicenter study aimed to investigate the clinical characteristics, treatment outcomes including mortality, and risk factors associated with death among patients with FG over the past 15 years in Korea. Materials and Methods: We retrospectively reviewed 84 patients diagnosed with FG between 2008 and 2022 across 7 hospitals. Demographics, comorbidities, laboratory findings, and clinical outcomes were analyzed. Mortality-related risk factors were assessed using univariate and multivariate logistic regression analysis.
Results
The mean age was 58.1±15.9 years, and 95.2% of patients were male. Diabetes mellitus (42.9%) and hypertension (36.9%) were the most prevalent comorbidities. Sepsis developed in 38.1% of patients, and the overall mortality rate was 14.3%. In univariate analysis, age ≥70 years, low body mass index, diabetes mellitus, low hemoglobin, low hematocrit, high respiratory rate, and Fournier gangrene severity index (FGSI) ≥9 were significantly associated with mortality. After data correction and multivariate adjustment, diabetes mellitus (odds ratio [OR], 39.61; 95% confidence interval [CI], 2.39–656.32; p=0.010) and respiratory rate (OR, 1.44; 95% CI, 1.09–1.91; p=0.011) were identified as independent predictors of mortality. FGSI≥9 demonstrated borderline association with mortality (p=0.08), indicating its potential clinical relevance.
Conclusions
In this multicenter Korean cohort, the mortality rate of FG remained substantial at 14.3%. Diabetes mellitus and elevated respiratory rate were independent predictors of mortality, while FGSI≥9 demonstrated a borderline yet clinically meaningful association, suggesting its role as a useful severity indicator in early risk stratification.

Korean Multicenter Study of Infectious Complications after Transurethral Prostate Surgery in Patients with Preoperative Sterile Urine: Seong Hyeon Yu, Seung Il Jung, Eu Chang Hwang, Tae-Hyoung Kim, Jae Duck Choi, Koo Han Yoo, Jeong Woo Lee, Dong Hoon Koh, Sangrak Bae, Seung Ok Yang, Joongwon Choi, Seung Ki Min, Hoon Choi; Urogenit Tract Infect 2022;17(3):81-88. Published online December 31, 2022; DOI: https://doi.org/10.14777/uti.2022.17.3.81

Purpose: To evaluate the efficacy of antibiotic prophylaxis and determine the risk factors of infectious complications after transurethral surgery of the prostate.
Materials and Methods: Seven hundred and seventy-two patients who underwent transurethral resection of the prostate (TURP) or holmium laser enucleation of the prostate (HOLEP) were reviewed. Of these, this study enrolled 643 patients without bacteriuria who had not received antibiotics for urinary tract infections for two weeks before surgery. The patients were divided into two groups according to the duration of the antibiotics (Group 1: less than one day, n=396 vs. Group 2: more than one day, n=247).
Results: The overall incidence of postoperative infectious complications in 643 patients was 5.0% (32/643). When postoperative infectious complications were compared according to the duration of the antibiotics (Group 1 vs. Group 2), the infectious complications rates were 5.6% (22/396) vs. 4.0% (10/247), respectively (p=0.393). When postoperative infectious complications were compared according to the duration of antibiotics (Group 1 vs. Group 2) in the TURP and HOLEP groups, the infectious complications rates were 6.3% (12/192) vs. 1.0% (1/103) (p=0.035) and 4.9% (10/203) vs. 6.0% (8/134) (p=0.677), respectively. The duration of Foley catheterization was independently associated with infectious complications (p=0.003).
Conclusions: The results showed that prolonged postoperative catheterization affects postoperative infectious complications associated with transurethral prostate surgery. Although antibiotics administered for less than one day are effective for antibiotic prophylaxis of transurethral prostate surgery, a longer antibiotic therapy is recommended for TURP.
