1. A pressure sensor array for urodynamic testing installed in a catheter, the pressure sensor array comprising:
a base substrate having flexibility, the base substrate comprising a lower surface and an upper surface opposing the lower surface, the base substrate comprises a first via hole and a second via hole spaced apart from each other and passing through the base substrate;
a bladder pressure sensor formed on a portion of the base substrate to be positioned in bladder and configured to measure bladder pressure;
a first readout element connected to the bladder pressure sensor and disposed adjacent to the bladder pressure sensor;
a prostate pressure sensor formed on a portion of the base substrate to be positioned in prostate and configured to measure prostate pressure;
a second readout element connected to the prostate pressure sensor and disposed closer to the prostate pressure sensor than the bladder pressure sensor;
a urethral pressure sensor formed on a portion of the base substrate to be positioned in urethra and configured to measure urethral pressure; and
a third readout element connected to the urethral pressure sensor and disposed closer to the urethral pressure sensor than the bladder pressure sensor and the prostate pressure sensor,
wherein the third readout element, the urethral pressure sensor, the second readout element, the prostate pressure sensor, the first readout element, and the bladder pressure sensor are arranged in this order on the base substrate,
wherein the prostate pressure sensor and the urethral pressure sensor are formed on the lower surface of the base substrate, and the bladder pressure sensor is formed on the upper surface of the base substrate,
wherein the second readout element and the third readout element are formed on the upper surface of the base substrate and are respectively electrically connected to the prostate pressure sensor and the urethral pressure sensor, formed on the lower surface of the base substrate, via the first via hole and the second via hole,
wherein the first readout element is formed on the upper surface of the base substrate,
wherein the bladder pressure sensor and the first readout element are connected to each other via circuit wiring,
wherein the prostate pressure sensor is formed in a first area of the base substrate,
wherein the urethral pressure sensor is formed in a second area of the base substrate,
wherein the bladder pressure sensor is formed in a third area of the base substrate, and
wherein the third area is smaller than each of the first area and the second area.
