Robotic versus Laparoscopic Partial Nephrectomy in the New Era: Systematic Review.

(1) Background: In recent years there have been advances in imaging techniques, in addition to progress in the surgery of renal tumors directed towards minimally invasive techniques. Thus, nephron-sparing surgery has become the gold standard for the treatment of T1 renal masses. The aim of this study is to investigate the benefits of robotic partial nephrectomy in comparison with laparoscopic nephrectomy. (2) Methods: We performed a systematic review according to the PRISMA criteria during September 2022. We included clinical trials, and cohort and case-control studies published between 2000 and 2022. This comprised studies performed in adult patients with T1 renal cancer and studies comparing robotic with open and laparoscopic partial nephrectomy. A risk of bias assessment was performed according to the Newcastle-Ottawa scale. (3) Results: We observed lower hot ischemia times in the robotic surgery groups, although at the cost of an increase in total operative time, without appreciating the differences in terms of serious surgical complications (Clavien III-V). (4) Conclusions: Robotic partial nephrectomy is a safe procedure, with a shorter learning curve than laparoscopic surgery and with all the benefits of minimally invasive surgery.

Renal Failure Management in Patients with Metastatic Renal Cancer Receiving Nivolumab: Evaluation from Two Points of View.

INTRODUCTION: Immunotherapy is recommended as category 1 in first-line treatment in metastatic renal cancer (mRC), however the evidence on the management of toxicities in patients with chronic renal failure is limited. Description of the Cases: Case 1: Patient with mRC and renal failure on hemodialysis. After 25 months of treatment with Nivolumab, he presented a partial response, without toxicities. Case 2: Patient with mRC undergoing treatment with Nivolumab-Ipilimumab, who after 6 cycles was admitted for acute renal failure, compatible with grade 4 nephrotoxicity, requiring definitive suspension of treatment, corticosteroid therapy and hemodialysis. CONCLUSIONS: Nivolumab is a safe and effective therapy in hemodialysis patients, not increasing adverse events, nor requiring dose adjustment. Immunotherapy nephrotoxicity must be adequately managed in daily clinical practice in an interdisciplinary way with the nephrologist.

Introducción: La inmunoterapia está recomendadacon categoría 1 en primera línea de tratamiento en cáncerrenal metastásico (CRm), sin embargo la evidencia sobre elmanejo de toxicidades en pacientes con insuficiencia renalcrónica es limitada.Descripción de los Casos: Caso 1: Paciente con CRme insuficiencia renal en hemodiálisis. Tras 25 meses detratamiento con Nivolumab, presenta respuesta parcial, sintoxicidades. Caso 2: Paciente con CRm en tratamiento conNivolumab-Ipilimumab, que tras 6 ciclos precisa ingresopor fracaso renal agudo, compatible con nefrotoxicidadgrado 4, requiriendo suspensión definitiva del tratamiento,corticoterapia y hemodiálisis.Conclusiones: El uso de Nivolumab es seguro y eficaz en pacientes en hemodiálisis, no incrementando losefectos adversos, ni precisando ajuste de dosis. Es fundamental conocer el manejo de la nefrotoxicidad por inmunoterapia en la práctica clínica diaria y establecer un enfoque multidisciplinar con nefrología. (AU)
