Table 1. Expression of E-cadherin, mast cell and TUNEL in bladder specimens of control and recurrent UTI patients.

	Control(n = 10)	Recurrent UTI (n = 30)	P-value
E-cadherin	42.4±16.7	25.4±8.9	<0.0001
Mast cell	1.3±1.2	2.5±1.8	0.046
TUNEL	0.08±0.3	1.5±1.8	<0.0001

Data are expressed as mean ± SD numbers of positive cells per 100 cells, for E-cadherin data are expressed as mean ± SD pixel of image per area unit (µm²).
