Fig. (4) Urinary osmolality in UUO. Osmolalities of urine collected from the bladder of SHAM operated rats, from the bladder and obstructed kidney of rats with 3 days of UUO, and from the bladder and obstructed kidney of rats with 10 days of UUO. Expressed as mean +/- standard deviation. SHAM = sham operated animal, 3d = 3 days, UUO = unilateral ureteric obstruction, 10d = 10 days. *p<0.001 vs SHAM BLADDER; #p<0.05 vs cognate bladder urine.
