Abnormal renal mobility--an indication for surgical intervention.

Movable kidney is a debated entity and therefore not diagnosed in many cases. According to our experience the diagnosis should be made much more frequent in patients who suffer from loin and/or abdominal pain which is relieved by recumbent position. Twenty-nine cases of patients who suffered from loin and/or abdominal pain and were diagnosed as suffering from abnormal renal mobility by medical history, intravenous pyelogram, angiography and dynamic scanning were operated upon with a reported high rate of relief of pain (87%; 25/29). The technique employed was the modified Deming operation.
