Introduction: Bladder outflow obstruction may cause obstructive or irritative symptoms. The diagnosis of female functional bladder neck obstruction requires a pressure/flow study and electromyography performed by videourodynamics. The treatment includes self-catheterization or bladder neck incision. We administered tamsulosin, an α₁A/α₁D-selective adrenergic antagonist, in women with functional bladder neck obstruction to evaluate its potential therapeutic effects. Patients andMethods: A group of 18 women affected by functional bladder neck obstruction was selected. The diagnosis was made by means of a pressure/flow study combined with electromyography and a fluoroscopic test. The diagnostic criteria were: high detrusor pressure with reduced maximum flow, silent electromyography activity, and bladder neck nonfunnelling during the fluoroscopic test. Tamsulosin 0.4 mg once daily was administered for at least 30 days. Patients with a postvoid residual urine volume ≧100 ml performed intermittent self-catheterization. Patients with a postvoid residual urine volume <100 ml performed self-catheterization every 7 days. After 30 days of therapy, all patients underwent a new pressure/flow study and a micturition fluoroscopic test. Results: 10 (56%) out of 18 treated patients showed a statistically significant improvement in symptoms, maximum flow, and postvoid residual urine volume (p < 0.01). Conclusion: The use of α₁-blockers may be an initial treatment option for female functional bladder neck obstruction, as this therapeutic option proved to be effective in more than 50% of our patients suffering from this voiding dysfunction.

The pelvic floor is a complex multifunctional structure that corresponds to the genito-urinary-anal area and consists of muscle and connective tissue. It supports the urinary, fecal, sexual and reproductive functions and pelvic statics. The symptoms caused by pelvic floor dysfunction often affect the quality of life of those who are afflicted, worsening significantly more aspects of daily life. In fact, in addition to providing support to the pelvic organs, the deep floor muscles support urinary continence and intestinal emptying whereas the superficial floor muscles are involved in the mechanism of erection and ejaculation. So, conditions of muscle hypotonia or hypertonicity may affect the efficiency of the pelvic floor, altering both the functionality of the deep and superficial floor muscles. In this evolution of knowledge it is possible imagine how the rehabilitation techniques of pelvic floor muscles, if altered and able to support a voiding or evacuative or sexual dysfunction, may have a role in improving the health and the quality of life.

We evaluated the agreement between wedged hepatic vein pressure (WHVP), portal vein pressure (PVP), and its relationship with portal hemodynamics in 21 patients with HCV-related cirrhosis with esophageal varices. Direct measurements of the portohepatic gradient (HVPG) were obtained by ultrasound-guided fine needle puncture of the right hepatic and the portal veins. In five cases PVP was 6.4-10.4 mm Hg higher than WHVP. In 12 cases measurements were similar (WHVP - PVP < or = 3 mm Hg). In the remaining four cases WHVP was 3.6-9.6 mm Hg higher than PVP. WHVP and PVP agreement was not related to HVPG mean value, Child-Pugh score, or grading of esophageal varices. By contrast, the difference between WHVP and PVP was inversely related to the portal flow velocity (P = 0.053) and directly related to the portal vascular resistance (P = 0.02). Whereas the portal branches were visualized in patients with WHVP lower or similar to PVP, a predominant left portosystemic collateral flow was observed in patients with WHVP > PVP. Our data point out that, in patients with cirrhosis due to hepatitis C virus infection, discrepant HVPG values reflect true hemodynamic differences.
