Mortality prediction model for patients with bladder urothelial tumor after radical cystectomy.

Objective: Based on preoperative clinical and postoperative pathological variables, we aim to build a prediction model of cancer specific mortality (CSM) at 1, 3, and 5 years for patients with bladder transitional cell carcinoma treated with RC.

Material And Methods: Retrospective analysis of 517 patients with diagnosis of cell carcinoma treated by RC (1986-2009). Demographic, clinical, surgical and pathological variables were collected, as well as complications and evolution after RC.

Effect of adjuvant chemotherapy in locally advanced urothelial carcinoma of the bladder treated with cystectomy.

Introduction: Currently, the role of adjuvant chemotherapy (ADJ) in muscle invasive bladder tumor remains controversial.

Objective: To evaluate the effect of ADJ on cancer specific survival of muscle invasive bladder tumor after radical cystectomy (RC).

Material And Methods: Retrospective analysis of 292 patients diagnosed with urothelial bladder tumor pT3-4pN0 / + cM0 stage, treated with RC between 1986-2009.

Virtual reality and intracorporeal navigation in urology.

Objective: To provide an overview of the meaning and types of virtual reality (VR) system, its current applications in the field of urology and future implications.

Synthesis Of The Evidence: The concept of VR involves the generation of computer environments with which a user can interact directly. Urology technologies and surgical practices are constantly evolving and RV simulation has become an important complement in urologist training curricula, taking into account not only simulations in surgical techniques, but also in non-surgical techniques such as communication and decision making.

[Partial orchiectomy in testicular tumor: Surgical technique and role of intraoperatory ecography.].

Objectives: Systematic review of the treatment of small testicular masses (STM) by testicular sparing surgery (TSS), including indications, surgical techniques and complications, as well as the correlation of the analysis of frozen sections (FSE) with the final tumor histology. As a secondary objective we report the initial experience of our center in TSS.

Material And Methods: A systematic literature search of the Medline/PubMed database for studies published until June 30, 2019 with the following keywords: "testis sparing surgery", "conservative surgery", "partial orquiectomy" "testicular neoplasms", "testis tumour", "Sex cord tumor", "intraoperative ultrasonography", "enucleation", "excision" or "resection" without time limits, in English and Spanish, identifying 20 articles with a total of 204 TSS, being the series with the largest sample size of 28.

Cavoscopy in the surgical treatment of renal cell carcinoma with vena cava thrombus. Systematic review.

Objective: To perform a literature review on the use of cavoscopy during surgery for renal cell carcinoma with vena cava thrombus (RCCVCT), according to the criteria of Evidence-Based Medicine.

Material And Methods: We performed a Pubmed search for studies published with the following keywords: "renal tumor thrombus", "renal tumor cavoscopy" and "cystoscopy thrombus", without time limit and in English. With these criteria, 5 articles were identified with a total of 41 patients.
