Resumen Introduccion Pocos son los estudios que comparan la prostatectomia radical abierta (PRA) con la prostatectomia radical laparoscopica (PRL) y sus resultados funcionales, como la continencia urinaria (CU), que es uno de los objetivos prioritarios tras el control oncologico. Objetivos Comparar la CU postoperatoria en los pacientes con adenocarcinoma de prostata localizado intervenidos mediante PRA frente a PRL. Material y metodos Comparacion de dos cohortes (312 con PRA y 206 con PRL) entre los anos 2007 y 2015. El estado de CU se recogio a los 3, 6, 12, 18 y 24 meses. Para el manejo estadistico hemos agrupado la continencia en: a) CU, pacientes que no precisaron absorbentes, y b) incontinencia urinaria (IU), pacientes que precisaron absorbentes. Para el contraste de variables cualitativas se ha utilizado el test de la chi cuadrado para las variables cualitativas y ANOVA para las cuantitativas. Analisis multivariable mediante regresion logistica para la variable dependiente IU. La significacion estadistica se considero cuando existio una p Resultados En el 51,7% se realizo conservacion neurovascular. A los 24 meses de la cirugia, el 72,4% presentaban CU, de los cuales el 87,8% con PRA frente al 78,1% con PRL (p = 0,004). El 22,7% presentaron recidiva bioquimica (RB), siendo el 83% tratados con radioterapia de rescate (RTR). Los pacientes con RTR presentaron mayor porcentaje de IU frente a los que no la recibieron (p = 0,036). Se objetivo mayor porcentaje de estenosis de la anastomosis en PRA (p = 0,03). Conclusiones La PRL, la no preservacion de los fasciculos neurovasculares y la RTR se relacionaron directamente con la CU postoperatoria.

Introduction There are very few articles comparing open radical prostatectomy (ORP) vs. laparoscopic radical prostatectomy (LRP) and their functional results or urinary continence (UC), which is one of the most important objectives to pursue after oncological results. Objectives to compare postoperative UC in patients with localized prostatic adenocarcinoma treated with OPR or LRP. Materials and Methods Comparison between two patient cohorts (312 for ORP and 206 for LRP) between 2007−2015. The UC was evaluated at 3, 6, 12, 18 and 24 months. Continence was defined and classified as follows: a) UC, no need of pads, and b) urinary incontinence (UI), use of pads. To compare the qualitative variables, we employed the chi-squared test and ANOVA for quantitative variables. We performed a multivariate analysis using logistic regression with dependent qualitative variable UI. Statistical significance when p Results Nerve-sparing was performed in 51,7% cases. At 24 months after surgery, 72,4% patients had UC, of which 87,7% were from the ORP group and 78,1% in the LRP group (p = 0,004). 22,7% of patients experienced biochemical recurrence (BR), with 83% treated with salvage radiotherapy (SRT), presenting greater UI percentage (p = 0,036). ORP patients showed a higher percentage of anastomosis stricture (p = 0,03). Conclusions LRP, non-nerve sparing, and SRT were directly related to postoperative IU.
