Cysto-Conray II is indicated for use in retrograde cystography and cystourethrography.
Unless contraindicated, an appropriate laxative is given the night before the examination.
The radiographic procedure normally employed for cystography and cystourethrography should be employed. A preliminary radiograph is recommended before the contrast agent is administered.
Sterile catherization is essential. Cysto-Conray II may be introduced by gravity flow using an appropriate venoclysis set or by syringe. Excessive pressure should be avoided with any method of administration.
Either Conray 43 supplied at 43% w/v or Cysto-Conray II supplied at a 17.2% w/v concentration may be used for these procedures. The desired concentration will vary depending upon the patient’s size and age and also with the technique and equipment used (SEE CONRAY 43 PACKAGE INSERT FOR SPECIFIC INFORMATION ABOUT THE USE OF THIS PRODUCT). 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. Adults usually require a volume in the range of 200 to 400 mL. Children require a volume in proportion to their body size. The usual dose ranges from 30 to 300 mL.
Store at 20° to 25°C (68° to 77°F) [see USP Controlled Room Temperature]. Exposing this product to very cold temperatures may result in crystallization of the salt. If this occurs, the containers should be brought to room temperature. Shake vigorously to assure complete dissolution of any crystals. The speed of dissolution may be increased by heating with circulating warm air. Before use, examine the product to assure that all solids are redissolved and that the container and closure have not been damaged.
This product is sensitive to light and must be protected from strong daylight or direct exposure to the sun.
As with all contrast media, the containers should be inspected prior to use to ensure that breakage or other damage has not occurred during shipping and handling. All containers should be inspected for closure integrity. Damaged containers should not be used.
