Also, patients on concomitant treatment with nitrates or calcium channel blockers or with severe hepatic impairment were excluded. A total of 267 patients with distal ureteric stones were assessed for eligibility to enter the study.

One hundred and sixty-five patients were excluded for different reasons (not meeting inclusion criteria 70 patients, refused to participate 54 patients and for other reasons 41 patients) as in Fig.

One hundred and two patients who fulfilled the inclusion criteria were enrolled in the study. Informed written consent was obtained from all the patients after explanation of the study procedures and the possible side effects. The patients were randomly divided into 3 equal groups, and each one consists of 34 patients using closed envelope method. Group I received silodosin 8 mg once daily, group II vardenafil 5 mg once daily and group III combination of silodosin 8 mg and vardenafil 5 mg once daily. The treatment was given for all the patients until stone expulsion or a maximum of 4 weeks.

Patients were assessed by history taking, general examination, serum creatinine, urine analysis, urine culture, KUB (kidney, ureter and bladder X-ray) and non-enhanced spiral CT. Patients were advised to take diclofenac 75 mg tablet orally during pain episodes along with the allocated drug. Patients were instructed to filter their urine to detect any passed stones.

Our study was planned as a double-blind study, and both the investigators and the participants were unaware of the type of the treatment received. Follow-up was performed weekly by history taking (stone passage, number of hospital visits for pain, total analgesia required and side effects associated with MET) and ultrasonography until spontaneous passage of the stone or stoppage of MET after 4 weeks. The primary endpoint was the stone expulsion rate, and the secondary endpoints were time to stone expulsion, number of hospital visits for pain, amount of analgesic required and side effects associated with MET. Data was collected, revised, coded and entered into the Statistical Package for Social Science (IBM SPSS) version 23.

Normality of data was checked using Kolmogorov–Smirnov test for normality. The comparison between groups regarding qualitative data was done by Chi-square test . The comparison between more than two independent groups with quantitative data and parametric distribution was done by one-way ANOVA test. There was no statistically significant difference between the groups for patient’s age, stone site and stone size ( P > 0.05) as in Table 1. The stone expulsion rate was significantly higher in combination than silodosin and vardenafil groups ( P = 0.025), the time to stone expulsion was significantly shorter in combination than silodosin and vardenafil groups ( P Table 2 Comparison between 3 groups regarding stone expulsion rate, stone expulsion time, number of hospital visits for pain and amount of analgesic required.

There was no significant difference among the studied groups regarding headache ( P = 0.749), dizziness ( P = 0.856), orthostatic hypotension ( P = 0.585).

However, incidence of retrograde ejaculation was significantly higher in silodosin and combination groups than vardenafil group ( P Table 3 Comparison between

A great advance in the MET has been

achieved

The ?-1 adrenoreceptor antagonists act by inhibiting basal muscular tone, uncoordinated hyperperistaltic wave frequency and ureteral contractions of distal ureter leading to relaxation of ureteral smooth muscles with subsequent ureteral lumen dilatation which results in increase in the rate of stone expulsion [11]. Recently, PDE5 inhibitors were reported to act on the nitric oxide (NO)/cyclic guanosine sex power tablet price monophosphate (cGMP) pathway in the smooth muscles, resulting in accumulation of cGMP, resulting in ureteral smooth muscle relaxation.

So, PDE5 inhibitors are potentially able to facilitate stone expulsion [8]. Despite having a well-established role in erectile dysfunction (ED) and benign prostatic hyperplasia (BPH), the use of viagra tablet online price PDE5 inhibitor for MET is in the preliminary stage. In our study, we found that the stone expulsion rate was significantly higher in combination than silodosin and vardenafil groups (90.0%, 76.7% and 60.0%, respectively) ( P = 0.025).

[12] reported that there was a higher expulsion rate 76% in combination therapy group compared to 73% in tadalafil group and 70% in tamsulosin group.

There was an increase in expulsion rate in patients with combination therapy, though statistical significance could not be demonstrated.

[6] reported

that

[13] reported that the stone expulsion rate was 58% for placebo group, 80% for tadalafil group and 74% for tamsulosin group. Tadalafil was superior to placebo in stone expulsion rate ( P = 0.017). The reason for a higher stone expulsion rate in combination group can be explained by the fact the combination of vardenafil and silodosin with different mechanisms of action.

Silodosin acts as ?-1A adrenoceptor blocker, whereas vardenafil acts as PDE5 inhibitor, and thus, the combination of the two drugs may further help in increase in stone expulsion [1].

In this study, we found that the mean stone expulsion time was significantly shorter in combination than silodosin and vardenafil groups (11.23 ± 3.14, 12.50 ± 1.66 and 14.67 ± 1.24 days, respectively, P 0.05).

This can be explained by the young age of the studied population. However, there was a highly significant difference among the studied groups regarding retrograde ejaculation (silodosin and combination = 86.7% vs vardenafil groups = 0.0%) ( P.

The combination of silodosin and vardenafil significantly increases the stone expulsion rate and decreases the time to stone expulsion. This combination also significantly decreases the pain episodes without incidence of serious side effects.

Cardiovascular Effects of the 3 Phosphodiesterase-5 Inhibitors Approved for the Treatment of Erectile Dysfunction. From the Heart Institute, Good Samaritan Hospital, and the Division of Cardiovascular Medicine, Keck School of Medicine, University of Southern California, Los Angeles.

Within the last year, 2 new phosphodiesterase-5 (PDE5) inhibitors have been approved by the US Food and Drug Administration (FDA) for the treatment of erectile dysfunction (ED).

Currently, sildenafil (Viagra), vardenafil (Levitra), and tadalafil (Cialis) are on the market. These agents have been shown to be effective in a broad population of men with ED, including patients with vascular disease, coronary artery disease,

hypertension

1–5 Because the enzyme that they inhibit, PDE-5, is found in smooth muscle cells of the systemic arteries and veins throughout the body, these agents have mild vasodilator effects and thus, have the potential to impact the cardiovascular system. 6 This fact is especially important for the patient with ED, because risk factors for ED include many of the same risk factors that are associated with coronary artery disease: lipid abnormalities, hypertension, smoking, diabetes, and lack of physical exercise. 7,8 Because erection is a vascular event, endothelial dysfunction may inhibit it.

9 Endothelial dysfunction, an early component of atherosclerosis, is rarely confined to the arteries supplying blood to the penis but more likely occurs throughout the vascular bed.

Kaiser et al 10 studied 30 men with ED and observed that brachial artery flow–mediated vasodilation and nitroglycerin-mediated vasodilation were reduced in these patients compared with men without ED. Thus, ED may be an early marker of vascular disease.

10 Patients with frank coronary artery disease, known to be associated with endothelial dysfunction, and frank atherosclerosis often have ED, as we recently observed in 1 study, in which three fourths of the men with chronic stable angina also reported some degree of ED. 11 Hence, the vasodilator effect of these PDE5 agents should be taken into consideration for the cardiac patient, both as a possible concern in some cases or a

Effect of PDE5 Inhibitors on Blood Pressure and Heart Rate.

Sildenafil was approved as an effective agent for treating ED in 1998, and its cardiovascular effects have been studied in great depth.

In 1 study of 8 volunteers, 12 80 mg of intravenous sildenafil reduced systolic blood pressure from 131±12 mm Hg with placebo to 122±13 mm Hg ( P 12 gave 8 healthy male subjects 100, 150, and 200 mg of oral sildenafil.

The mean maximum reduction in supine systolic/diastolic blood pressure was 10/7 mm Hg at 3 hours after dosing, with no difference in the 200-mg versus the 100-mg dose.

In most subjects, blood pressure returned to baseline within 6 hours. The authors did not observe a significant orthostatic drop in blood pressure or increase in heart rate in the standing position. Sildenafil, as expected, reduced vascular resistance.

In patients with stable ischemic heart disease 40 mg of intravenous sildenafil reduced systolic arterial pressure from 150±12 to 141±16 mm Hg (mean±SD) and diastolic blood pressure from 74±8 to 66±10 mm Hg but had no effect on heart rate.

Cardiac output was 5.6±0.9 L/min at baseline and 5.2±1.1 L/min sex power tablet price after intravenous sildenafil.

Pulmonary artery pressure fell from 16.7±4.0 to 12.1±3.9 mm Hg.

Subsequent studies verified that sildenafil results in small reductions in systolic and diastolic blood pressure, with little or no effect on heart rate. 13–15 In addition, sildenafil was shown in numerous studies of pulmonary hypertension to reduce sex power tablet price pulmonary vascular resistance and pulmonary artery pressure (PDE5 is rich within the pulmonary vasculature).

Vardenafil was the second PDE5 inhibitor to come to market in the United States, and it was approved by the FDA in 2003.
