Morbidity and mortality of renal exploration for cyst.

Surgical exploration for a renal mass is a procedure associated with a low mortality and morbidity, even in a population with a median age of 58 years, most of whom were listed according to the American Society of Anesthesiologists as class II or greater. As a consequence, the procedure warrants serious consideration as a diagnostic measure. Nonsurgical diagnostic procedures are associated with less immediate risk to the patient but with less immediate risk to the patient but with more limited accuracy. The decision as to which methods of evaluation to use in each particular patient must be individualized. The general and related symptoms, physical and laboratory findings and the quality and results of roentgenography and puncture studies of the patient warrant consideration in recommending a reasonable course. Whatever procedures are recommended, the patient should be adequately informed to recognize that alternative treatment approaches are available.
