N/A Various urodynamic studies have been used in patients with bladder outlet obstruction in order to evaluate the degree of obstruction, the results of therapy and postprostatectomy conditions. Radionuclide urodynamic study was performed in 27 patients with bladder outlet obstruction and 30 normal controls. The parameters evaluated were voiding time, 50% voiding time, average flow rate, peak flow rate, corrected peak flow rate, ejection fraction of the bladder and residual urine. Voiding time, 50% voiding time and residual urine of patients were significantly larger than controls and average flow rate, peak flow rate, peak corrected flow rate and ejection fraction were significantly lower in patients. This method was noninvasive procedure for determining of voiding parameters and it avoids the extraexamination needs to determine the residual urine.

N/A Vasculogenic impotence is produced by abnormalities of vascular blood supply or drainage, and is the most common cause of various organic impotences. An increasing awareness of vascular causes of impotence has resulted from development of various diagnostic tests, but precise measurement of penile blood flow is difficult. Radionuclidc penogram has been introduced recently to diagnose vasculogenic impotence. Forty-one impotent patients and 12 normal men were studied with radionuclide erection penogram using Tc-99m pertechnetate and an intracavernous injection of papaverine. We defined arteriogenic impotence as arterial index less than 0 66, and vcnogenic impotence as venous index greater than 0.09. By this criteria, the false positive ratio in normal men was 17% and the false negative ratio in radically cystectomized patients was 0%. Side effects were small purpura of the penile shaft and dull pain during injection of papaverine. The radionuclide erection penogram was noninvasive and gave a dynamic evaluation of the arterial supply, venous drainage, and blood flow in the corporeal bodies. This method should be considered as a valuable adjunct to evaluate patients with vasculogenic impotence.
