Future Prospects for Urodynamic Study in Clinical Evaluation of Benign Prostatic Hypertrophy
It is estimated that one-third of all men older than 60 have enlarged prostates, yet only 25% of them complain of voiding dysfunction.7 Many of these men also have no gross symptoms of obstructed flow. These observations are in accord with the findings of Yalla et al.,12 who discovered that men with moderate or even severe enlargement of the prostate can be without symptoms of obstruction. When tested by urodynamic methods, obstruction was found to be either mild or altogether absent. On the other hand, Platenkamp9 observed that totally asymptomatic men can have occult obstruction that may not be evident unless sensitive testing techniques are used. Using the urinary drop spectrometer (UDS), 461 apparently normal men in the armed services (age 19–55 years) were surveyed at random. They produced a total of 4109 voidings. Of the 461, Platenkamp found 29 who had UDS patterns that were compatible with obstruction. The age groupings of the men in the study and of those with abnormal UDS patterns are shown in Table 1.
