We report on 3 cases of femoral neuropathy following radical surgery f
or urologic malignancy. The defect was bilateral in 2 patients. Compre
ssion from self-retaining retractors was the presumed mechanism of inj
ury in all patients. Spontaneous improvement was observed in each case
although the symptoms did not resolve completely. The pathophysiology
contributing to this operative complication as well as measures for p
revention and treatment are discussed.
