Sensitive method for intraoperative roentgenograms.
A new technique using mammography film has been developed. A portable x-ray machine and mammographic film has been used to obtain excellent intraoperative radiographs of renal calculi. The kidney is exposed through a flank incision. The film is cut to a size and shape that will permit an easy fit behind the kidney. Exposed film is developed in an automatic processor. This technique has facilitated location and removal of small calculi and faintly opaque calculi. Uric acid stones have been demonstrated in vitro. It is an inexpensive technique that requires no special equipment.
