Infections and Tumors of Kidney MCQs

Nephron-sparing surgery with the recent increase in incidental detection of small renal masses (tumours Partial nephrectomy should be the treatment of choice in tumours less than 4cm, in well-selected tumours between 4 and 7cm, in bilateral tumours, in tumours in solitary kidneys and in patients with pre-existing renal dysfunction. Radical nephrectomy is limited to tumors >7cm Minimally invasive techniques by laparoscopy or robots have reduced postoperative morbidity. Because of the limitation of ischaemia time, minimally invasive techniques should be reserved for tumours with non-complex anatomy, as predicted by nephrometry scores. Alternative techniques such as surveillance, cryoablation or radiofrequency ablation of small renal tumours may be offered in patients with high surgical risk (e.g. elderly patients, patients with multiple comorbidities).
