Background: The aim of this study is to compare two different preparations in patients undergoing transrectal prostate biopsies samples (TPBS) and assess the prevalence of genitourinary infections (GUI).
Methods: A historical cohort of patients undergoing TBPS for suspected prostate cancer. Two groups were compared: one with endorectal lubricant jelly and another with the addition of a povidone-iodine lubricating jelly. Complications were evaluated at three weeks. A bivariate analysis was performed by calculating the OR (95 % CI) to determine if the additional endorectal povidone-iodine pre-TBPS reduced GUI and other complications.
Results: 185 patients (Group I n = 86, Group II n = 96) were evaluated. 45 and 25 % had genitourinary tract infection (OR: 0.4, CI: 0.2-0.9, p = 0.004); fever was presented in 21 and 10 % respectively (OR: 0.42, CI: 0.1-0.9, p = 0.04).
Conclusions: A reduction was observed in the presence of genitourinary infections in patients who had intrarectal povidone-iodine preparation applied.
Introducción: el objetivo de este estudio es comparar dos preparaciones distintas en pacientes sometidos a la toma de biopsias prostáticas transrectales (BPTR) y evaluar la prevalencia de infecciones genitourinarias (IGU). Métodos: se compararon dos grupos de pacientes con sospecha de cáncer de próstata sometidos a Biopsia Prostática Transrectal (BPTR): Con jalea lubricante endorrectal (grupo l, cohorte histórica) y con jalea lubricante más iodopovidona (grupo II, cohorte prospectiva). Se evaluaron las complicaciones a las tres semanas. Se realizó un análisis bivariado, calculando su OR (IC: 95 %) para determinar si la iodopovidona endorrectal adicional previa a la BPTR disminuye las IGU y otras complicaciones. Resultados: Se evaluaron 185 pacientes (Grupo I n = 86; grupo II n = 96). Tuvieron infección del tracto genitourinario el 45 y 25 % (OR: 0.4, IC: 0.2-0.9, p = 0.004); la fiebre se presentó en el 21 y 10 % respectivamente (OR: 0.42, IC: 0.1-0.9, p = 0.04). Conclusiones: Se observó una reducción en la presencia de infecciones genitourinarias en pacientes a quienes se aplicó en su preparación iodopovidona intrarrectal.
