Zero ischaemia partial nephrectomy: a call for standardized nomenclature and functional outcomes

The introduction of partial nephrectomy for the removal of small renal masses has enabled preservation of patients' renal function. However, this technique involves clamping of the renal hilum, resulting in ischaemia. In the past 5 years, researchers have developed a variety of techniques described as 'zero ischaemia'. Here the authors describe these various techniques and their outcomes, highlighting a need for standardized nomenclature and outcome measures.
