Parenchymal volume and functional recovery after clamped partial nephrectomy: potential discrepancies

PVA is highly accurate for predicting SRF in PN patients preoperatively and for assessing functional outcomes in patients managed with hypothermia or limited WI. However, with prolonged WI, there is discordance between parenchymal volume and function that progressively increases beyond 24 minutes. Avoidance of prolonged WI should be considered in patients with solitary kidneys and/or significant pre-existing chronic kidney disease.
