This retrospective study demonstrates 16G needles provide more glomeruli, more diagnostically adequate renal tissue, with fewer cores without a significant increase in complications compared with 18G needles. Based on these observations, 16G needles should be considered as the first line option in native-kidney PRB.

In patients with autosomal dominant polycystic kidney disease (ADPKD), drinking more water could potentially reduce urine osmolality and suppress arginine vasopressin release and decrease the rate of kidney cyst growth and its associated organ dysfunction. In a 3-year trial, adults with ADPKD randomized to drink more water so as to lower urine osmolality did not have slower kidney growth than did a group who drank water as they wished.
