High Intensity Focused Ultrasound (HIFU) Ablation for Treatment of Prostate Tissue in Bladder Outlet Obstruction

Objectives: To assess the efficacy of HIFU therapy for benign prostatic tissue ablation in patients with lower urinary tract symptoms (LUTS) due to bladder outlet obstruction (BOO) that caused by Benign prostatic hyperplasia (BPH). The primary objective of the study is to determine the efficacy of HIFU therapy by assessing the changes in IPSS score in 6-month post HIFU procedure for BPH with compared to baseline. The secondary objectives of this study are as follow: * To assess any adverse events related to the procedure or device. * To assess the operation related characteristics including: total operation time and ablation time required in HIFU procedure for BPH, total catheterization time after the HIFU procedure for BPH, and categorical ablation zone * To assess the patient's post operative pain level at different post op time points. * To assess the urinary flow and symptoms improvement by studying the changes in IPSS, Qmax, and PVR at different post op time points compared to the baseline. * To assess the effectiveness of HIFU by studying the changes in PSA levels, types of medication for BPH or any urologic condition, proportion of patients who are taking BPH medication, prostate volume, and prostate calcification level and the reoperation rate within 12-month post-op. * To assess changes in patients' sexual function at different post op time points. The hypothesis is that a HIFU ablation is a safe and effective treatment for patients with LUTS due to BOO from BPH.

INTUPRO in the Treatment of Benign Prostatic Hyperplasia-Related Symptoms

The goal of this clinical trial is to determine whether INTUPRO can improve the quality of life in patients with Benign Prostate Hyperplasia (BPH). The main questions it aims to answer are: Can INTUPRO treatment lead to the removal of the Foley catheter? Can INTUPRO treatment improve urinary flow? Can INTUPRO treatment lower or minimize waking during sleep to urinate? Can INTUPRO reduce urinary hesitancy, urgency and frequency? Participants will: Receive INTUPRO treatment on Day 1. Visit at Day 30 and Day 90 for checkups, tests and Prostate MRI.

US Imaging for the Assessment of LUTS

The purpose of this research is to develop an ultrasound (US) based urodynamics (UDS) evaluation of voiding based on successful magnetic resonance imaging (MRI)-UDS evaluation. Both US and MRI are non-invasive imaging techniques, but US is a more cost-effective and widely available technology. 80 participants will be enrolled and will be on study for up to 2.5 hours (1.5 hour MRI and 1 hour US).

Blue Diode Laser Vaporization for BPH

This is a prospective data collection of subjects using blude diode laser for the treatment of BPH.

Effect of Group Preoperative Pelvic Floor Training for HoLEP

The main goal of this study is to see if group pelvic floor training before surgery can help prevent urinary incontinence after Holmium laser enucleation of the prostate (HoLEP) surgery. The study has the potential to inform preoperative intervention strategies for managing incontinence after HoLEP.

Proof-of-concept Study to Evaluate the Safety and Efficacy of Tryptophan in Patients with BPH.

Benign prostatic hyperplasia (BPH) is one of the most prevalent human diseases and a major cause of lower urinary tract symptoms (LUTS). Some men respond to current medical treatment (mainly α-1 adrenoreceptor antagonists and 5 α-reductase inhibitors), but a large proportion of patients continues to need a surgical procedure to treat resistant LUTS or even more serious complications of BPH, creating the emerging necessity for novel pharmacological therapies. Oxitriptan may have a possible positive effect on BPH associated symptoms with probably no impact in sexual function (which is a common side effect of the current drugs for BPH associated symptoms). Also, improvement in symptoms could be higher than that of current drugs used for this condition. This is a single-center parallel group, randomized clinical trial. The study will take place in Hospital de Braga (Urology department). Eligible patients will be randomized to receive tamsulosin 0.4mg (once a day, q.d.) or 5-HTP (5-hidroxitriptophan) 100mg (three times a day, t.i.d.), for 6 months.

Evaluation of SureCore Plus Biopsy System

This is a post-market study of a cleared biopsy system. The quality of tissue cores varies with standard of care biopsy needles. The SureCore Plus biopsy system is being evaluated as to quality and volume of tissue from prostate biopsy as compared to standard of care biopsy needles.

Prostate Enucleation With Intravesical Botox Injections in Treating BPH and Bladder Overactivity

The aim of this study is to evaluate the effect of intravesical Botox injections on lower urinary tract symptoms (LUTS) when administered during Bipolar prostate enucleation surgery in patients with bladder outlet obstruction (BOO) and overactive bladder symptoms (OAB).

Intra-operative Loop Diuretics to Improve Same-day Discharge Rates After HoLEP

Holmium Laser Enucleation of the Prostate (HoLEP) is a size-independent treatment option for benign prostatic hypertrophy (BPH) as recommended by the American Urological Association (AUA) Guidelines. Loop diuretics (furosemide) have been given historically during the morcellation portion of HoLEP to promote urine production in the post-operative setting and to minimize the impact of fluid absorption during long periods of morcellation. The intra-operative use of 20mg IV furosemide in perioperative HoLEP pathways has been propagated with the dissemination of HoLEP across North America without evidence to support its routine administration. With increasing surgical efficiency from improvements in laser and morcellator technology, the role of intra-operative furosemide is unknown. This study is designed to assess if there is a significant difference in same day discharge rates after Holmium Laser Enucleation of the Prostate (HoLEP) with and without IV furosemide. .

Long Term Safety and Efficacy of Butterfly Medical Prostatic Retraction Device in Benign Prostatic Hyperplasia (BPH) Patients Who Completed 12 Months of Follow-Up Post Implantation (Continuation Study for Study BM-011-IL)

This study evaluates the long term safety and efficacy of use of the Butterfly Medical's prostatic retraction device in Benign Prostatic Hyperplasia (BPH) Patients. The study follows patients implanted with the Butterfly device for up to 5 year after implantation. The evaluations include recording of safety events and BPH related symptoms by Uroflowmetry tests, residual urine and International Prostate Symptom Score (IPSS) questionnaires. The study also assesses the sexual quality of life after implantation of the Butterfly device.
