Two cases of xanthogranulomatous pyelonephritis are reported in Negroes. The clinical findings are similar to those in previously reported cases. In 1 case nephrolithotomy was followed by the development of a perinephric abcess 8 months later. Late diagnosis has limited experience with more conservative management, which should be reserved for demonstrably focal disease.

A series of 29 femoropopliteal bypass operations is described. The patients were selected carefully to exclude those with clinical and aortographic evidence of aorto-iliac disease. ⋯ There was a highly significant difference in the result of the operation between patients with a pulsatility index of 4 or more in the common femoral artery and patients with a pulsatility index of less than 4. We concluded that calculation of this pulsatility index provides useful additional evidence when selecting patients suitable for a femoropopliteal bypass.
