Cystography is the method of roentgenologic examination of the bladder. For cystography use solution of sergazina, cardiotest, diodon or other contrast agents. Cystography can be ascending and descending.
For ascending (retrograde) cystography in entering the bladder through the catheter 150-200 ml 10-30% solution of one of contrast agents and produce x-rays in direct and oblique projections at horizontal position of the patient on his back and stomach. On zitohroma judged on the shape and size of the bladder.
Cystography helps identify stones, anomalies, diverticula, tumors and other diseases of the bladder.
When introduced into the bladder oxygen or carbon dioxide this study called pneumocystography. To establish the prevalence of tumor process used sedimentary pneumocystography using introduction into the bladder barium suspension and oxygen, as well as paleographie (see), combining pneumocystography with the introduction of oxygen in paravesical (kolapushinu) tissue.
Descending (excretion) cystography produce during urography (see), in 1-2 hours after intravenous administration of contrast, when the latter accumulates in the bladder.
