Fig. (5) Urinary electrolyte and urea values in UUO. Electrolyte profiles 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. Na = sodium, K = potassium, Cl = chloride, 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; $p<0.001 vs 10d UUO BLADDER), &p<0.05 against all other groups.
