Objective: To evaluate the results of nephropexy in patients with a diagnosis of symptomatic mobile kidney that had been established by dynamic sonography with provocation of pain.
Design: Prospective study.
Setting: University hospital, Sweden.
Subjects: 19 consecutive patients with symptomatic right-sided mobile kidney and 6 controls who had urographically mobile kidneys but no pain.
Interventions: Dynamic sonography and dislocation of the kidney by manipulation. All 19 patients experienced pain on manipulation and the 6 controls did not. The 19 patients were treated by nephropexy and followed for at least four years postoperatively.
Main outcome measure: Relief of pain after nephropexy.
Results: In 16/19 patients the pain was relieved by nephropexy.
Conclusion: Dynamic ultrasound is useful in correlating the abnormal position of the kidney with pain, and successfully indicates those patients whose symptoms will be relieved by nephropexy.
