Introduction and Objectives: Advances in assisted reproductive techniques (ART) have caused an increase in requests for postmortem sperm retrieval (PMER). The use of these techniques is usually tied to legal, ethical and medical/casuistic problems. The objective of this work is to analyze technical and legal aspects of PMER in Spain using two real cases and to establish guidelines to help in decision-making after a PMER request., Material and Methods: Two real cases in which a PMER was requested and others published in Spain in recent years are presented. We proceed to an exposition of the techniques used in postmortem ART cases and specifically in PMER, and a detailed study of the current legal framework is carried out., Results: In Spain we have a complete law on ART. Article 9 expressly requires an authorization from the deceased male partner for the use of his reproductive material in the following 12 months. Regarding the PMER, technical and logistical considerations require a quick and organized decision-making. The time until extraction should not exceed 24-36hours from death and a good choice of biological material is essential., Conclusions: Medical-scientific advances now allow PMER and the use of postmortem ART. A good knowledge of the technical, logistical and legal aspects is necessary for a fast and coordinated action., (Copyright © 2022 Asociación Española de Andrología, Medicina Sexual y Reproductiva.

Objective: The aim of this study was to develop a postoperative prognostic nomogram for disease-free survival in patients with renal adenocarcinoma., Materials and Methods: A total of 224 patients with organ-confined or locally advanced renal adenocarcinoma were treated with radical or partial nephrectomy. The variables included in the model were age, histological type, pathological stage, Fuhrman grade and DNA ploidy. Tumor recurrence was defined as any clinical evidence of recurrence. The probability of progression-free survival was calculated using the Kaplan-Meier estimate, and multivariate analysis was performed using a Cox regression. The nomogram was created using the data obtained from the Cox regression., Results: Tumor recurrence was detected in 89 patients (39.74%). The median progression-free time in these patients was 9.55 months (range 0-133). Of these patients, 70.9% relapsed during the first 2 years, and only 15 patients (6.9%) were alive but ill at the end of the study. The probability of progression-free survival at 5 and 10 years was 66.64 and 61.97%, respectively. We performed a statistical validation of the model with accurate predictions that were discriminated with a confidence interval of 0.75 (comparing the predicted and actual probability). According to the nomogram obtained, patients with low-grade, diploid, organ-confined tumors would be candidates for follow-up not exceeding 5 years due to the low probability of recurrence (<40 points)., Conclusion: The nomogram we developed is clinically relevant and can provide prognostic information for both patients and researchers. In addition, it can be used by researchers during the monitoring protocols that categorize patients based on their relative risk of disease progression., (Copyright © 2012 S. Karger AG, Basel.)
