Two techniques are available for endovascular treatment of post-SAH vasospasm: mechanical angioplasty and phamacologic infusion(papaverine or other vasodilator). The advantages of papaverine infusion are simplicity, safety, and the ability to reach small distal vessels. The disadvantages are that the treatment results may be temporary and inconsistant. The advantages of balloon angioplasty are rapid, dramatic result and consistantly successful. It is important to treat vasospasm as soon as possible for two reasons: vascular response is better and permanant ischemic damage is minimized. If ischemic symptom have developed, it may already to be late. So, the treatment of vasospasm should be proreactive rather than reactive.

Snap Gauge bands were applied to measure nocturnal penile rigidity in the impotent patients and the results were compared with PBI and findings of the papaverine induced artificial erection. The results were as follows: 1. The results of Snap Gauge test were relatively competitive with the degree of erectile dysfunction which organic impotent patients complained of. 2. PBI less than 0.85 implied insufficient rigidity and PBI over 0.95 showed sufficient rigidity in Snap Gauge tests. 3. The possibility of "false positive" or "false normal" in diagnosis of the impotence was higher in the papaverine induced artificial erection tests than in the Snap Gauge tests. Conclusively, Snap Gauge band is simple to use and effective to measure quantitatively the penile rigidity reached during nocturnal erections in impotent patients.

A variety of technique of dynamic pharmacocavernosometry have been described to evaluate cavernous veno-occlusive function: however, there is no uniquely reliable and standard method so far After intracavernous (IC) injection of 45 mg papaverine and 2.5 mg phenblamine, we performed gravity cavernosometry(GC) and pump cavernosometry(PC), ie, measurement of saline infusion rate needed to obtain and to maintain an erection and measurement of pressure decay for 30 seconds and pressure drop time to 75 mmHg when pump was turned off at 150 mmHg IC pressure. Final diagnosis of venous leakage was made by cavernosoeraphy done at 90 mmHg IC pressure. The parametric values measured by each method to diagnose venous leakage and correlation among these methods were analyzed. The etiology of impotence in 45 patients studied was psychogenic in 8, venogenic in 21, combined arteriogenic and venogenic in 16. The measurement of induction flow rate was less reliable(p<0.05) for the diagnosis of venous leak than the other methods of PC and GC (p<0.01). The standard deviations of the induction and maintenance flow rate and pressure drop time were similar to or even higher than mean values. There was correlation among all these methods. Therefore, GC and PC, particularly measurement of the intracorporeal pressure decay are believed to be valuable methods for diagnosis of the corporal-venous leakage.

To determine whether intracavernous injection of papaverine can discriminate vascular versus psychogenic impotence 40mg papaverine were injected intracorporally into 203 importens. And the diagnostic usefulness of intracavernous papaverine-induced artificial erection was compared with Snap Gauge test, penile brachial index(PBI), internal pudendal angiography and cavernosography. The results obtained were as follows ; 1. Among the 119 psychogenic impotent patients, 104(87.4%) showed full rigid erection and 1(0.8%) soft or absent erection at 5 minutes after injection, and 88(73.8%) full rigid erection and 2(1.7%) soft or absent erection at 30 minutes after injection. Among 33 patients with arteriogenic impotence none showed full rigid erection and 20(60.6%) soft or absent erection at 30 minutes. Among 12 patients with venous leak only one(8.3 %) showed full erection at 5 minutes, and none fully rigid erection and 7(58.3%) soft or absent erection at 30 minutes. 2. Of the 78 patients with an abnormal Snap Gauge test, the response papaverine injection was absent in 37(47.4%) and fully rigid erection in 11(14.1%). Of the 105 patients with a normal Snap Gauge test the response was full erection in 89(84.7%) and absent in 2(1.9%). 3. Among 17 patients of PBI < 0.75, 14(82.4%) showed soft or full erection and one(5.9%) full erection with papaverine injection. Among 186 patients of PBI >=0.75, 26(13.9%) showed soft or absent erection and 113(60.7%) full erection with papaverine injection. 4. Among 27 patients with severe arterial lesion on arteriogram, the response to papaverine injection was absent in 18(66.7%) and full erection in one(3.7%). Among 20 patients with severe venous leak on cavernosogram the response to papaverine injection was absent in 12(60.6%) and full erection in one(5.0%). Therefore, we conclude intracavernous papaverine-induced artificial erection is the best valuable test for differentialdiagnosis of psychogenic and vasculogenic impotence.

After pelvic trauma, complications of urethral stricture and organic impotence may develop. Certain cases of these are combined with penile curvature, which treatment method of artificial erection alone is not suitable, because severe penile pain may occur during erection, Therefore proper surgical methods should be added for straightening the penile curvature. After pelvic trauma, complete urethral stricture and organic impotence with penile curvature developed in 3 patients who complained severe pain due to curvature during the intracavernosal injection test. To all, treatment of choice for complete urethral sticture was visual internal urethrotomy for prevention of further development of curvature, and for curvature, Nesbit's penile straightening operations were performed, one by one. All patients could well urinate and enjoy their sexual intercourse after intracavernosal injection of PGE1 or papaverine. We recommend visual internal urethrotomy and the Nesbit's operation as effective methods to treat the case of penile curvature combined with complete urethral stricture after pelvic trauma.
