This study aimed to assess the sensitivity of the Malay version of the Brief Manual Sexual Function Inventory (BMSFI) on patients with and without urinary symptoms in Malaysian population. Validity and reliability were studied in patients with lower urinary tract symptoms (LUTS) and patients without LUTS. Reliability and validity was evaluated by using the test-retest method while internal consistency was assessed by Cronbach's alpha. Sensitivity to change was expressed as the effect size in the pre-intervention versus post-intervention score in patients who underwent transurethral resection of the prostate (TURP). Internal consistency was excellent. A high degree of internal consistency was observed for each of the 11 items and 5 domains (Cronbach's alpha value = 0.67 and higher and 0.73 and higher respectively). Test-retest correlation coefficient for the 11 items scores was highly significant. Intraclass correlation coefficient was high (ICC = 0.68 and above). The sensitivity and specificity showed a high degree of sensitivity and specificity to the effects of treatment. A high degree of significant level between baseline and post-treatment scores were observed across 3 domains in the treatment corresponds cohort but not in the control group. The Mal-BMSFI is a suitable, reliable, valid and sensitive to clinical change in the Malaysian population.

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.

Penile duplex sonography with intracorporeal papaverine injection has been proposed as a reliable noninvasive method to evaluate the cavernosal arteries. To provide insight into the clinical value of this test. penile duplex sonography was comparatively analyzed with penile brachial index. nocturnal penile erection and selective internal pudendal pharmacoangiography in 60 patients suggestive of arteriogenic impotence. The duplex sonogram, penile brachial index and angiogram of both cavernosal arteries were evaluated separately and compared each other. Cavernosal arteries were interpreted as normal by duplex scanning if the artery demonstrated a 75% or greater increase in diameter and systolic peak flow velocity of greater than 25 cm/sec after intracorporeal injection of 60 mg or papaverine HCI. There was no significant difference between the degree of arterial dilatation and peak flow velocity on penile duplex sonogram. Arterial dilatation and peak flow velocity did not correlate with nocturnal penile erection and cavernosal arteriogram. But peak flow velocity correlate with penile brachial index. In conclusion. although penile duplex sonography is a useful method to evaluate the cavernosal arteries. it alone can make an error to misdiagnose the arteriogenic impotence. Therefore supplementary tests should be added to the duplex sonography to avoid this error.

We recently experienced a case of hypervascularization of the glans after arterialization of the deep dorsal vein(Furlow`s method) in a 25-year-old man having vasculogenic impotence due to arterial insufficiency of the penis. The Hypervascularization of the glans was corrected by ligating the branches of the deep dorsal Vein at the corona of the penis.

Penile-brachial Index(P. B. I) was measured before and after injection of papaverine in 79 psychogenic impotences, 31 arteriogenic impotences and 11 neurogenic impotences. Its diagnostic usefulness was compared with qualities of papaverine induced artificial erection and pudendal angiographic findings. The results were as follows , 1. Among 31 patients with arteriogenic impotence, 17(54.8%) patients were above 0.8 in P. B. I before injection of papaverine. Thus, the arteriogenic impotence could not be excluded in patients of P. B. I. above 0.8. 2. Among the psychogenic impotences, there was no case of P. B. I. below 0.8 after injection of papaverine. So arteriogenic impotence could be like in the case of P. B. I. below 0.8. However, the arteriogenic impotence could not be excluded in the case of P. B. I. above 0.8 because 25(86.6%) patients of arteriogenic impotence were above 0.8. 3. The specificity. sensitivity and efficiency of the P. B. I. concerning prediction of response to papaverine injection were 88.2, 41.2, 80.4% in P. B. I. of 0.8. 4. The specificity, sensitivity and efficiency of the P. B. I. concerning prediction of findings of pudendal angiogram were 71.4, 90.3, 86.8% in P. B. I. of 0.9. In conclusion, it was difficult to establish the base line of normal value of P. B. I. and there was limitation of diagnostic value of the P.B.I.

Diagnosis of vasculogenic erectile dysfunction (ED), which can not based on single method, is the key for the successive surgical treatment. Revascularization is a safe, effective method to treat arteriogenic ED. The key for successive treatment is to select the most suitable patients and to avoid any risk factors for the surgical candidates, especially for those revascularization as the only therapeutic method. The high failure rate in surgery of ED is due to venous leakage which has led to these techniques being abandoned by almost all urologist. Newly appeared methods with little or no damage are welcome by the patients with vasculogenic ED, and the better results can be achieved by the combination of general treatment.

Recent evidence implicates NO (Nitric oxide) as the principal mediator in an erection. To investigate the role of NO in the human erectile function, we studied the distribution pattern of nitroxergic fibers in the corpus cavernosum specimens obtained from 38 men using nicotinamide adenine dinucleotide phosphate diaphorase (NADPH-d) histochemistry. Diffusely scattered delicate nerve fibers showing blue color reaction after NADPH-d histochemical staining were observed in normal control specimens from potent men. The neurogenic impotence group showed a statistically-significant decrease in the number of positive fibers compared to the normal control group. The number of positive fibers in the non-neurogenic impotence group was decreased compared to the normal control group but was statistically insignificant. With nitric oxide synthase (NOS) immunohistochemical stain, immunoreactive nerve bundles were easily seen in normal control specimens from potent men. NOS immunoreactive nerve bundles were contained within the corpus cavernosa which stained with NADPH-d reaction. Our results suggest that nitric oxide, a potent smooth muscle relaxing neurotransmitter in the autonomic nervous system, plays a physiologic role in erectile function and NADPH-d enzyme histochemical staining on the biopsied corpus cavernosum may be used as an important diagnostic method in the evaluation of neurogenic impotence.

Penile and digital systolic pressures were measured with Doppler ultrasonic sthetoscope in 65 normal subjects. This technique is simple, reliable, inexpensive OPD procedure for the detection of penile arterial lesion in patients with impotence. With this study, we concluded that normal men have a PDI ratio above 0.77, and impotent men have a. PDI ratio below 0.63. However, the ratio range from 0.63 to 0.77 is borderline range which is not clearly impotent or normal. Hyperemic stress test is indicated the patient with borderline range. Pelvic steal test can detect vascular pathological condition previously missed by PDI. We indicate this test in the patients with history of intermittent gluteal claudication. We concluded that arteriogenic impotence is easily diagnosed by PDI combined with hyperemic stress test and pelvic steal test, if indicated.
