Table 2. The correlation between bladder wall thickness (BWT) and parameters of urodynamic diagnosis.

Parameters of UDS	BWT <3.0 mm (n=25)	BWT ≥3.0 mm (n=23)	P-value
Qmax (mL/s)	25.24±9.08	23.91±11.26	0.187
VLPP (cmH2O)	73.58±89.50	89.50±41.05	0.064
MUCP (cmH2O)	46.20±16.32	48.52±19.97	0.319
Functional length (mm)	28.76±4.84	29.29±5.06	0.538
PVR (mL)	16.28±25.21	17.39±38.60	0.488
Duration of symptoms (mon)	62.36±59.80	43.74±30.52	0.009

Values are expressed as mean±standard deviation.

UDS, urodynamic study; VLPP, Valsalva leak point pressure; MUCP, maximal urethral closure pressure; PVR, postvoid residual volume.
