RESUMO

Background: Fournier's gangrene is an infectious urological emergency with associated morbidity and varying rates of mortality in the world. Various predictors of mortality such as advancing age, Fournier's Gangrene Severity Index (FGSI), anatomical extent of the disease, or presence of risk factors have been studied in the literature, though with conflicting results. Aim: The aim of the study was to determine the presentation and predictors of mortality in our environment, Nigeria. Patients and Methods: A review of medical records of all the patients managed from April 2012 to December 2018 at a tertiary referral center in Nigeria was conducted. Data on clinical presentation, FGSI, management, and outcome were retrieved and analyzed. Statistical Analysis: Descriptive studies using mean and standard deviation were used for continuous variables, Fischer's exact test was used to compare categorical variables among survivors and nonsurvivors, and logistic regression analysis was used to describe the relationships of these variables with mortality. Results: The mean age of the 31 patients was 60 ± 12 years. All were men, with 9 (29.0%) patients without clinical evidence of immunosuppression or predisposing factor (idiopathic). Fourteen (45%) had documented evidence of immunosuppression. All the patients had a polymicrobial infection; however, Escherichia coli was the most common organism cultured seen in 26 (83.9%) patients. The initial empirical antibiotic regimen of choice was a combination of intravenous ceftriaxone and metronidazole in 26 (83.8%) patients and intravenous ciprofloxacin and metronidazole in 5 (16.1%) patients. Mortality was recorded in three patients representing a rate of 9.6%. Anatomical extent of the disease, anemia requiring blood transfusion, severity of infection, and FGSI were all found to be the statistically significant variable of mortality in these patients using the Fischer exact test. Furthermore, on regression analysis only the FGSI and blood transfusion were significant with P < 0.05. Conclusion: Fournier's gangrene is a disease of the older men with a higher mortality rate when the FGSI is >9 or anemia requiring blood transfusion is present.


RésuméContexte: La gangrène de Fournier est une urgence urologique infectieuse associée à une morbidité et à des taux de mortalité variables Dans le monde. Divers prédicteurs de mortalité tels que l'âge avancé, l'indice de gravité de la gangrène de Fournier (FGSI), l'étendue anatomique. De la maladie ou la présence de facteurs de risque ont été étudiés dans la littérature, mais avec des résultats contradictoires. Objectif: le but du L'étude visait à déterminer la présentation et les prédicteurs de la mortalité dans notre environnement, au Nigeria. Patients et méthodes: un examen de la Des dossiers de tous les patients pris en charge d'avril 2012 à décembre 2018 dans un centre de référence tertiaire au Nigéria ont été réalisés. Les données Sur la présentation clinique, FGSI, la gestion et les résultats ont été récupérés et analysés. Analyse statistique: études descriptives Utilisant la moyenne et l'écart type ont été utilisés pour les variables continues, le test exact de Fischer a été utilisé pour comparer les variables catégorielles Parmi les survivants et les non-survivants, et une analyse de régression logistique a été utilisée pour décrire les relations de ces variables avec Mortalité. Résultats: l'âge moyen des 31 patients était de 60 ± 12 ans. Tous étaient des hommes, avec 9 (29,0%) patients sans preuve clinique D'immunosuppression ou de facteur prédisposant (idiopathique). Quatorze (45%) avaient des preuves documentées d'immunosuppression. Tout Les patients avaient une infection polymicrobienne; cependant, Escherichia coli était l'organisme le plus couramment cultivé chez 26 (83,9%) Les patients. Le schéma antibiotique empirique initial de choix était une association de ceftriaxone intraveineuse et de métronidazole. 26 (83,8%) patients et ciprofloxacine et métronidazole par voie intraveineuse chez 5 (16,1%) patients. La mortalité a été enregistrée chez trois patients Représentant un taux de 9,6%. Étendue anatomique de la maladie, anémie nécessitant une transfusion sanguine, gravité de l'infection et FGSI Ont tous été trouvés comme étant la variable statistiquement significative de la mortalité chez ces patients en utilisant le test exact de Fischer. En outre, Sur l'analyse de régression, seuls le FGSI et la transfusion sanguine étaient significatifs avec P <0,05. Conclusion: la gangrène de Fournier est une Maladie des hommes plus âgés avec un taux de mortalité plus élevé lorsque le FGSI est> 9 ou une anémie nécessitant une transfusion sanguine est présente.

RESUMO

BACKGROUND: The presentation and management of the recurrent urethral stricture varies and depends largely on the initial treatment and the characteristics of the recurrent stricture. What are the likely determinants of recurrence? PATIENTS AND METHODS: This is a retrospective review of all patients who had urethroplasties from January 2013 to December 2017 for anterior urethral strictures in our institution. Patients with a recurrence of the strictures were identified and reviewed, while patients with hypospadias and posterior urethral stenosis or contractures were excluded from the study. The etiology, length, site, and type of urethroplasties were evaluated as variables that may contribute to the recurrence of strictures using inferential statistics and logistic regression analysis. Time to recurrence was analyzed using the Kaplan-Meier method. RESULTS: A total of 206 urethroplasties for anterior urethral strictures were evaluated with recurrence of strictures noted in 29 patients and a recurrence rate of 14.1%. Recurrence was higher in long-segment strictures, penobulbar strictures, and postinflammatory strictures. Pedicle flaps were used in 45% of the strictures that reoccurred. Using Chi-square, the length, site, of urethroplasties were statistically significant determinants of recurrence; however, only the site of stricture was found to be statistically significant following logistic regression analysis. The site of recurrence was in the bulbar urethra in 79% and the penile urethra in 21%. The choice of treatment of the recurrent strictures was anastomotic urethroplasty in 76.5%. The mean time to failure in this study was 13 months with a range of 6-120 months. CONCLUSION: In this study, the site of stricture was found to be the most determinant of stricture recurrence, with penobulbar strictures mostly implicated. Long-segment strictures were also noted to contribute to some extent in recurrence. These recurrent strictures were mostly short-segment strictures in the bulbar urethra which were amenable to excision and anastomosis to achieve cure.
