Resumen
Antecedentes: Actualmente en la literatura se observa una tendencia a una correlación baja entre el puntaje internacional de síntomas de la próstata y la uroflujometría en diversos estudios efectuados en diferentes regiones del mundo con asociación tanto significativa, como no significativa en la correlación.
Metodología: Estudio retrospectivo en el cual se recolectaron 79 hombres con diagnóstico de hiperplasia prostática (HPB) que consultaron por síntomas obstructivos urinarios bajos al Centro Especializado de Urología de Neiva, entre enero de 2020 y mayo de 2021. La recolección se realizó mediante la revisión de la base de datos del centro médico. Todos los pacientes debían tener registrado el resultado de la uroflujometría y del IPSS.
Resultados: La edad promedio fue de 65 años. La media del IPSS fue de 11.5, con un 50% que fueron clasificados con severidad moderada. La mediana del Qmax de 12 ml/segundo, y fue clasificada como anormal en un 38,46% de los casos. El volumen miccional presentó una mediana de 280 ml.
La correlación entre las dos pruebas fue de -0.293 (p=0.009). Al efectuar un análisis entre el nivel educativo y el valor del IPSS, en el grupo con mayor nivel de formación académica la correlación fue de -0.40 (p=0.728).
Conclusiones: A medida que se presenta un puntaje mayor de IPSS, el índice del Qmax disminuye. El análisis de correlación mostró una correlación negativa y débil, pero significativa.
Descripción
Abstract
Background: Currently in the literature there is a trend towards a low correlation between the international score of prostate symptoms and uroflowmetry in various studies carried out in different regions of the world with both a significant and non-significant association in the correlation.
Methodology: This is a retrospective study in which 79 men with a diagnosis of prostatic hyperplasia (BPH) who consulted the Centro Especializado de Urologia en Neiva for lower urinary obstructive symptoms were collected, between January 2020 and May 2021. The collection was carried out through the review from the medical center database. All patients had to have their uroflowmetry and IPSS results registered.
Results: The average age was 65 years. The IPSS mean was 11.5, with 50% being classified as moderate severity. The median Qmax was 12 ml / second, and it was classified as abnormal in 38.46% of the cases. The voiding volume presented a median of 280 ml.
The correlation between the two tests was -0.293 (p = 0.009). When carrying out an analysis between the educational level and the IPSS value, in the group with the highest level of academic training the correlation was -0.40 (p = 0.728).
Conclusions: As a higher IPSS score is presented, the Qmax index decreases. Correlation analysis showed a negative and weak correlation, but significant.
