Occult progressive renal damage in the elderly male due to benign prostatic hypertrophy.

A review of the case histories of 345 patients who underwent protatectomy showed that 1.7 percent (6 patients) had "occult and progessive renal damage" secondary to prostatic hypertrophy. All these men were over the age of 60 and the disturbances in micturition were so mild that the patients were unaware of, or chose to ignore them. The presenting symptoms were nonspecific and included generalized weakness, anorexia, nausea, constipation, and weight loss. Investigation revealed impaired renal function of varying degrees. Prostatectomy was associated with a dramatic improvement in all 6 patients. Physicians should be aware of the clinical entity of occult and progressive renal damage secondary to obstruction of the bladder outlet, especially in the elderly male. Uremia can develop with minimal urinary symptoms. Elderly men often suppress or deny their symptoms because of the fear of operation.
