Evaluation of the effectiveness of four alternative approaches for the classical cough test during a urodynamic study in the context of the COVID-19 global pandemic

Table 2 Different kinds of alternatives compared with the classical cough test

Approach	Amplitude(mean ± SD^bcmH20)	P value	Case Number(n)
Cough test(classic)	73.14 ± 22.48	N/A^a	120
Quickly pressing the bladder area	66.17 ± 17.12	0.076	120
Performing the Valsalva maneuver	82.93 ± 18.95	0.182	120
Performing the Kegel maneuver	26.50 ± 8.68	< 0.05	120
Letting the patient close their mouth while performing a cough test	68.90 ± 20.32	0.342	120

ALL urodynamic study system was air catheter system (ACS); P < 0.05 shows statistically significant; 1cmH20 = 0.133kpa
