The lowest possible concentration giving satisfactory contrast should be employed. The use of undiluted Cysto-Conray should be necessary only in selected adult patients. The bladder should be emptied before the contrast agent is instilled. The radiographic procedure normally employed for cystography, cystourethrography and retrograde pyelography should be employed. A preliminary radiograph is recommended before the contrast agent is administered.
Sterile catheterization is essential.
Excessive pressure should be avoided with any method of administration. About 5 to 6 mL are usually administered for each exposure. The desired concentration will vary depending on the patient's size and age and also with the technique and equipment used. Sufficient volume of contrast medium is administered to adequately fill the urinary bladder. The volume of solution required will vary depending upon the individual patient.
