ABSTRACT
Radical treatments and active surveillance are valid therapeutic approaches for low-risk prostate cancer. The oncologic effectiveness and morbidity of Radical Prostatectomy (RP) and radiotherapy have been broadly validated. Focal therapies pursue to reduce the morbidity observed after radical treatments, while preserving the oncologic effectiveness. This study aims to review the state-of-the-art about principles, oncologic effectiveness, morbidity, and side-effects associated with leading focal therapies. We review and summarize articles related with Cryotherapy, High-Intensity Focal Ultrasound (HIFU), Photodynamic Therapy (PDT), and Irreversible Electroporating (IRE) published in MEDLINE from 2000 to 2022. There is a wide heterogeneity in terms of the measurement of effectiveness and morbidity. Hence, comparing different energies, strategies and protocols seem to be unprecise and controversial. Cryosurgery and HIFU have reported more clinical experience than PDT and IRE. Biochemical recurrence rate after the first session varied from 4.5% to 23%, and up to 20% of patients underwent a salvage radical treatment. The reported incidence of erectile disfunction and urinary incontinence ranges from 3% to 50% and 0% to 34%, respectively. None randomized clinical trial comparing any focal therapy to any radical treatment has been published. We conclude that the expansion of focal therapies requires the consolidation of MRI-guided fusion biopsies in everyday clinical practice. Short-term oncologic effectiveness has been proved and supports their usefulness in low-risk patients unfit for surgical treatment. However, long-term effects and the clinical experience in intermediate and high-risk patients remains limited. Currently none of the focal therapies can be considered the Gold Standard for low-risk patients.

OBJECTIVE: Renal malformations are rare entities and rarely have clinical consequences. Crossed renal ectopia has an incidence of 1/2.000 autopsies. The association with aortic aneurysm is even more exceptional. METHODS: We present our case and perform a bibliographic review. RESULTS: To date and in our knowledge, seven cases of crossed renal ectopia associated with aortic aneurysm were described on the literature. This malformation makes the treatment of the aneurysm more complex. The possibility of renal function decrease caused by injuries to the renal arteries during the surgical procedure is always present. Because of this risk of injury of the kidney during surgery preoperative evaluation of the vascularization must include image technologies as the MRI, CT-angiography or conventional arteriography. During the aortic intervention vascular conservation must be performed and it is necessary to minimize the time of renal ischemia. CONCLUSIONS: The association of crossed renal ectopia and aortic aneurysm is a rare event. The surgical intervention of the aorta does not have to necessarily originate a loss of renal function. Anyway the worsening of the renal clearance must be foreseen.

OBJETIVO: La malformación renal es una entidad poco frecuente y rara vez tiene traducción clínica. La ectopia renal cruzada tiene una incidencia de 1 de cada 2.000 autopsias. Su asociación con un aneurisma aórtico es todavía más excepcional.MÉTODOS: Presentamos nuestro caso y revisamos la literatura.RESULTADOS: Hasta la fecha y en nuestro conocimiento hay descritos 7 casos de ectopia renal cruzada con fusión asociados a aneurisma aórtico. Este fenómeno hace que el tratamiento del aneurisma sea más complejo pudiendo ocasionar una disminución de la función renal por lesiones en su vascularización. Para evitarlo, la vascularización renal debe ser estudiada preoperatoriamente mediante pruebas como la RM, el Angio-Tac o la Arteriografía. Durante la intervención sobre la aorta se deben realizar técnicas de conservación vascular y se debe de minimizar el tiempo de isquemia renal.CONCLUSIONES: La asociación de riñón ectópico cruzado y aneurisma de aorta es un evento raro. La cirugía o procedimientos sobre la aorta no tienen por qué acarrear una perdida de función renal importante y ésta debe ser prevista antes de la intervención (AU)
