Urologic disorders after forty.

New trends have emerged in the management of urologic disorders that commonly present after 40. Surgical treatment of stone disease has largely been replaced by reliable nonoperative methods. Advances have been made in the design of penile prostheses. New concepts of the natural history of urinary tract infection and incontinence have made diagnosis and treatment more effective and less costly. Lack of progress in treating disseminated urologic cancer has reinforced the urgency of prompt diagnosis and treatment.
