• Aerocyst — An anatomical structure in the shape of a bladder, pouch, or sac filled with air, found in the stem or leaf structure of certain aquatic plants and marine algae (such as those of the genus Fucus). This floating vesicle functions as a natural hydrostatic organ, keeping the plant at the water surface to capture a maximum amount of sunlight required for photosynthesis.
• Aerocystography — A radiological method for investigating the urinary bladder consisting of performing radiographs after the bladder cavity has been distended by insufflating a controlled amount of air or another sterile gas. This imaging examination highlights the contour of the bladder walls, detecting radiolucent tumors, calculi, or diverticula, functioning as a negative contrast medium.
• Aerocystoscope — An endoscopic medical instrument specially designed for the direct visual examination of the inside of the urinary bladder after it has been mechanically distended by insufflating sterile air or another gas, instead of liquid. This device allows the urologist to inspect the bladder mucosa without the optical distortions sometimes caused by fluids.
• Aerocystoscopy — A method of direct visual endoscopic examination of the inside of the urinary bladder using an aerocystoscope, after the cavity has been mechanically distended by insufflating sterile air or another gas. This diagnostic or therapeutic procedure allows a meticulous inspection of the bladder mucosa and small surgical interventions without using a liquid medium.
