Active clinical trials for "Hyperplasia"

Restenosis due to neointimal hyperplasia causes repeat target vessel revascularization in a relevant number of patients undergoing percutaneous coronary interventions (PCI). Drug-eluting stents (DES) are currently adopted to reduce the rate of restenosis; however, they may increase risk of stent thrombosis. Experimental data and first clinical experiences showed that inhibition of neointimal hyperplasia may be obtained by local administration of anti-proliferative drugs (like paclitaxel) loaded on the surface of angioplasty balloons. Data on the efficacy of novel coronary drug-eluting balloons (DEBs) are lacking. Aims of this open label prospective, randomized trial is to evaluate neointimal hyperplasia in patients undergoing bare-metal stent (BMS) implantation alone compared to those receiving additional DEB use and to assess if the technique of DEB use may affect the degree of neointimal hyperplasia. Neointimal hyperplasia will be assessed by Optical coherence tomography (OCT).

The objective of the study is to confirm that the efficacy of vaginal progesterone is at least as good as oral progesterone in order to protect the endometrium of uncontrolled proliferation and prevent endometrial cancer.

The purpose of this study is to assess the effect of saw palmetto and sanmiaoshan, on top of alpha blocker, on urinary flow rate and BPH symptoms in patients with BPH.

Arteriovenous grafts are used as the vascular access in 40-50% of hemodialysis patients. Grafts are prone to recurrent stenosis (narrowing) and thrombosis (clotting). Graft clotting is usually due to a narrowing at the site where the graft joins the vein. The standard treatment is to remove the clot and angioplasty the narrowed area. The long-term outcome is not good, lasting only about 1 month. Placing a stent (a small metallic, PTFE covered, spring) at the narrowed site may keep the graft open longer. Principal investigator's preliminary research data suggest that placing a stent at the stenotic site prolongs graft patency following thrombectomy, as compared to conventional angioplasty. This is a single-center, randomized clinical trial, in which patients with a clotted graft with underlying stenosis at the venous anastomosis of the graft will be allocated to thrombectomy + angioplasty (control group) or to thrombectomy + stent placement (study group). The primary endpoint will be primary (unassisted) graft patency. The secondary endpoints will be secondary (assisted) graft patency and overall access-related costs.

The study objective is to assess the safety and efficacy of iTind three to five years following treatment.

The purpose of this study is to conduct an open, randomized controlled clinical trial, evaluating the effects of different dosage forms of glucocorticoid on the Recovery of Reproductive Function in Patients With 21α-hydroxylase Deficiency.

A multicentre randomised controlled trial evaluating the benefit of median lobe preservation on the incidence of retrograde ejaculation during prostate enucleation by HoLEP.

Prostate adenoma or benign prostatic hypertrophy (BPH) is a benign disease of the prostate gland. It results in an increase in the volume of the prostate area located in contact with the urethra. Compression of the prostatic urethra by the adenoma can cause lower urinary tract disorders. The classic treatments in case of failure of medical treatment are endoscopic resection of the prostate and adenomectomy, but these techniques are characterized by a significant hemorrhagic risk that may require transfusions and prolonged hospitalization. Minimally invasive treatments with low morbidity have been developed to overcome these drawbacks. They allow to propose a therapeutic solution adapted to patients: not tolerating their medical treatment, wishing to keep antegrade ejaculation, elderly and/or frail, at risk of bleeding, wishing an ambulatory treatment, refusing the conventional surgical techniques. The Focal One® device was developed to treat prostate cancer using ultrasound energy. This energy is delivered through a probe placed in your rectum. Connected to this probe, an ultrasound machine will allow your doctor to see precisely which part of your prostate is being treated. By heating the prostate tissue to a very high temperature in one treatment session, the energy delivered will then destroy the tissue. Ultrasound guidance coupled with the localized nature of the treatment allows the targeted area to be treated while respecting the prostate tissue and structures adjacent to the prostate and thus reducing side effects. Treatment of prostate adenoma with HIFU would allow for localized destruction to reduce prostate volume. The reduction of the compression of the prostatic urethra thus obtained would allow an improvement of the urinary disorders. The treatment is performed transrectally under real-time ultrasound control, which allows the adjacent structures to be respected, thus preserving antegrade ejaculation and limiting the side effects.
