A simple technique of manometric scintigraphic retrograde cystography was applied prospectively to 125 patients (85 per cent children) with 142 studies. 99mTechnetium sulfur colloid (0.5 to 1 mCi.) was instilled in the bladder followed by increments of normal saline under manometric control. The sensitivity of the test was increased when the filling phase was concluded at 25 cm. water pressure rather than when the patient complained of fullness (usually at 15 cm.). The studies had a voiding phase that was essential for patients in whom pressures greater than 15 cm. could not be achieved. Reflux was not detected on the voiding phase alone in 5 patients and the voiding phase could not be performed in 5 of 34 positive studies. It was not possible to predict volumes of fluid instilled to achieve satisfactory pressures. Monitoring during the entire study was necessary to diagnose reflux, which may occur at low or high pressure, or while voiding only.
