[Open and minimally invasive partial nephrectomy. Management of complications].

Current guidelines increasingly recommend organ-preserving surgical procedures in the treatment of renal tumors. Both the open surgical and minimally invasive surgical techniques are well established. In the literature, various systems for the systematic evaluation of comorbidities and complications have been reported. Already while taking the patient's history and preoperative planning prior to partial nephrectomy, it is recommended that a detailed risk assessment be carried out regarding expected complications. Essentially the two critical factors - the comorbidities of the patient and anatomic complexity level of the tumor - should be evaluated in order to achieve the best possible selection of patients for a partial nephrectomy and the determination of the surgical method.
