ABSTRACT

ABSTRACT Background: Multiparametric magnetic resonance imaging improves the performance of prostate cancer (PCa) diagnostics through a better selection of patients. Objectives: The aim of the study was to study the detection rate (DR) of systematic and targeted cognitive biopsies in a cohort with the previous negative systematic biopsies. A secondary objective was to describe the value of prostate-specific antigen density (PSAd) in the detection of clinically significant PCa (CSPCa). Methods: We designed a prospective, single-center, and comparative study to determine the DR of systematic and targeted cognitive biopsies. The clinical and pathological characteristics of each patient were described. Results: A total of 111 patients with Prostate Imaging Reporting and Data System lesions > 3 were included in the study. PCa was detected in 41.4% (46 of 111 patients); 42 (91.3%) were detected by systematic biopsy and 30 (65.2%) by targeted biopsy. CSPCa was detected in 26 (23.4%), 23 (88.5%) by systematic biopsy, and 21 (76.9%) by targeted biopsy. PSAd > 0.15 was directly associated with CSPCa. Conclusion: The detection of PCa by systematic biopsy in this series was higher than 80%; hence, its routine use should not be replaced by targeted biopsy, since it continues to be the cornerstone of the diagnosis in patients with prior negative biopsies.

ABSTRACT

Objetivo: Presentar nuestra experiencia en el tratamiento de la insuficiencia venosa, empleando el Ecodoppler para el diagnóstico.Antecedentes: El tratamiento de la insuficiencia venosa hasta hace algunos años se basaba en la manifestación de la enfermedad, hoy en día hemos comprendido la hemodinamia de la insuficiencia venosa y podemos efectuar tratamientos funcionales conservando la circulación venosa superficial.Método: De noviembre de 1997 a noviembre del 2000 realizamos un Ecodoppler venoso a 80 pacientes con sintomatología atribuible a insuficiencia venosa, el estudio se clasificó como normal, incompetencia leve, moderada y severa. Se correlacionó con la clínica y se decidió el tratamiento.Resultados: De los 80 pacientes 54 fueron tratados conservadoramente, 32.5 por ciento fueron intervenidos quirúrgicamente. Los procedimientos realizados fueron: ligaduras altas, ligadura de comunicantes y fleboexcéresis limitadas. Los resultados funcionales fueron excelentes en 80.7 por ciento, buenos en 11.5 por ciento y malos en 7.6 por ciento; 19.2 por ciento requirió tratamiento estético complementario.Conclusiones: El Ecodoppler venoso permite determinar la causa de la insuficiencia venosa. Se pueden obtener resultados funcionales aceptables, permite una evaluación fisiológica completa del sistema venoso y se logra conservar safenas.
