The eDM3d is a useful tool easily filled in by patients with a high satisfaction rate. Adequate validation of the eDM3d is required.

Aim To validate an electronic 3‐day bladder diary (BD) as an easy‐to‐use app for smart‐phone (eDM3d). Methods Descriptive and cross‐sectional prospective study. One hundred and thirty‐six patients with overactive bladder syndrome (OABs) or nocturia who had a smart‐phone and attended the urology clinics of a tertiary hospital from June to November 2017 were included. Patients filled the eDM3d (test) and the Spanish validated paper BD (DM3d) and questionnaires ICIQ‐UISF and BASQ during the first week. Two weeks later, they repeated the eDM3d (retest). We assessed feasibility of the eDM3d (percentage of variables completed), test‐retest reliability (qualitative variables: McNemar test; quantitative variables: ICC), paper‐app correlation (qualitative variables: Kappa index; quantitative variables: ICC) and convergent validity (correlation between eDM3d and questionnaires, Spearman's rank test). Patients answered a question about satisfaction: “If you had to repeat a BD again, would you choose paper or the app version?” Results One hundred and twenty‐three (90.4%) participants completed all the variables of the first eDM3d. There were no significant differences in the proportion of patients classified as positive for each symptom between test and retest. ICC ranged from 0.73 to 0.94 for all variables (P < 0.001) in the test‐retest assessment. Paper‐app correlation was good to excellent for all variables (ICC 0.76‐0.95, P < 0.001; Kappa index 0.56‐0.84, P < 0.001). Correlation between the eDM3d and the questionnaires ranged from 0.23 to 0.6 (P < 0.01). 120 (88.2%) patients would choose the eDM3d if they had to repeat a BD. Conclusion The eDM3d presents suitable feasibility, reliability, and validity to assess patients with OABs or nocturia who have a smart‐phone.

La cirugía NOTES (Natural Orifice Transluminal Endoscopic Surgery) es una modalidad quirúrgica que utiliza las vísceras huecas para acceder a la cavidad peritoneal, evitando así incisiones en la piel. Si combinamos este tipo de cirugía con la laparoscopia convencional, obtenemos una técnica híbrida que nos permitirá abordar órganos grandes, como el riñón, disminuyendo al máximo las incisiones cutáneas. Presentamos el primer caso de nefrectomía radical híbrida transvaginal por cáncer renal. Para poder realizar este procedimiento, se utilizó el acceso vaginal para la colocación de una cámara deflectable y la asistencia de dos puertos abdominales. La incisión del trócar vaginal se amplió para la extracción de la pieza quirúrgica. La nefrectomía híbrida transvaginal NOTES asistida debe considerarse, una técnica quirúrgica factible y reproducible que debe ser considerada como opción terapéutica en pacientes mujeres candidatas a nefrectomía por cáncer renal.
