Symptomatic pyelonephritis in elderly men.

A prospective study was carried out of the clinical, laboratory, radiologic and therapeutic features of acute, symptomatic, bacterial pyelonephritis as experienced by 12 consecutive elderly, noncatheterized men who required hospitalization. In spite of the advanced ages of the men and the inordinate frequency of bacteremia and septic shock, no patient died. "Appropriate" antibiotic therapy, supportive treatment, and, as importantly, a lack of associated "imminently" or "ultimately" fatal illnesses contributed to the 100 per cent survival rate. Guidelines are provided for the diagnostic evaluation and antibiotic therapy of community-acquired pyelonephritis in elderly men.
