The investigators wish to perform a prospective study at the Men's Health Clinic in Winnipeg, Manitoba to accomplish two goals: 1) Prospectively describe 1 year outcomes for MIST therapies performed at the clinic 2) perform a head to head comparison of Rezum water vapor therapy vs the iTind device in respect to symptom score improvement, uroflow parameters and side effect profile.
A randomized, double-blind, placebo-controlled, parallel group study to compare 2 extracts of saw palmetto versus placebo on the symptoms of benign prostate hyperplasia (BPH) in 120 generally healthy participants, 45 - 80 years.
Histologically, BPH is a benign proliferative process involving both epithelial and stromal elements and is characterised by progressive enlargement of the prostate. Symptom complex including increased frequency of urination, sudden feeling of urge to urinate, nocturia, difficulty in urinating, feeling of incomplete emptying of the bladder, decreased flow rate and intermittent urination are called lower urinary tract symptoms (LUTS). The most important cause of LUTS in men is BPH. Many structural and physiological changes occur in the lower urinary system with bladder outlet obstruction. Detrusor hypertrophy and bladder hyperactivity may occur due to bladder outlet obstruction. Although the density of afferent and efferent nerves in the bladder decreases after urethral obstruction, enlargement of their trunks indicates that changes occur in these nerves. In addition, changes also occur in the neural pathways of the central nervous system following lower urinary tract obstruction. Nerve growth factor (NGF) and brain derived neurotropin factor (BDNF) are trophic proteins that act as retrograde messengers between peripheral effector tissue and the nerves that innervate it. In peripheral tissues, the source of NGF and BDNF is presumed to be the target tissues innervated by nerves. Smooth muscle cells, fibroblasts, astrocytes and other cells synthesise NGF and BDNF in culture medium. Many potential stimuli that increase NGF in the lower urinary system have been identified. These are denervation, inflammation and mechanical tension. This information has led to the idea that autonomic innervation changes in the bladder may be related with changing NGF levels. Altered afferent and adrenergic innervation in the obstructed bladder increases the possibility that NGF plays an important role in this neural growth because this type of nerves are highly sensitive to this neurotrophin. In this study, we investigated NGF ve BDNF levels in urine samples obtained before surgery (Transurethral Prostate Resection, Prostate Enucleation with Holmium Laser and Prostate Enucleation with Thulium Fibre Laser) and after removal of obstruction in patients with bladder outlet obstruction secondary to benign prostatic enlargement using ELISA method, We aimed to determine the role of NGF and BDNF in bladder outlet obstruction and bladder changes secondary to obstruction by comparing with control patients without obstruction.
The purpose of this study is to assess the safety and efficacy of the DTT106 in the treatment of erectile dysfunction associated with benign prostatic hyperplasia

There are many factors that affect uroflowmetry parameters. One of these is the urination position. Research has mostly focused on standing and sitting urination positions. However, those who prefer the standing position as a habit can urinate by opening the zipper or lowering the trousers. Although the effect of these two applications on uroflowmetry parameters in healthy men has been investigated in only one study, their effect on patients with lower urinary tract symptoms has not been examined.
Objective: Rezūm vapor ablation is a minimally invasive treatment for benign prostatic hyperplasia (BPH) that uses injections of sterile water vapor directly into the prostate for tissue ablation. Although Rezūm is currently indicated for use in men with prostate sizes ≥30 and ≤80 ml, it is unclear how effective Rezūm is for men in urinary retention. The investigators sought to determine whether Rezūm is effective in the treatment of catheter-dependent urinary retention secondary to BPH.
Positron emission tomography (PET), an advanced diagnostic imaging technique, exploits the annihilation of positrons (e+) to delineate pathological alterations within diseased tissues. Integral to PET scanners are detector systems that transform gamma photons into fluorescent photons, thereby gleaning insights into the energy, time, and spatial distribution of gamma photons emanating from positron-emitting radiopharmaceuticals. Conventional PET scanners, bear a significant financial burden primarily due to their reliance on LSO (lutetium oxyorthosilicate) or LYSO (lutetium yttrium oxyorthosilicate) scintillation crystals. The exorbitant cost and limited availability of these crystal scintillators impede the widespread adoption of PET scanners. In a departure from conventional PET technology, the prototype J-PET scanner employed in this trial employs plastic scintillators, characterized by unique physical properties. This prototype is further equipped with bespoke software enabling three-photon imaging based on the annihilation of ortho-positronium (o-Ps) generated within diseased tissue. This study delves into the clinical applicability of PET scanners employing plastic scintillators, particularly investigating the feasibility of PET imaging using plastic scintillators where gamma quanta interact by mechanisms other than the photoelectric effect. Furthermore, this study endeavors to contemporaneously acquire and analyze data related to the lifetime of ortho-positronium (o-P) atoms emanating from routine radiopharmaceuticals. Additionally, it seeks to validate the utilization of a novel diagnostic indicator, termed the "positron biomarker," through a prospective study, comparing its efficacy to conventional diagnostic PET scanning methodologies.
This is a single-center pilot randomized controlled trial among 68 physically "inactive" older men with lower urinary tract symptoms (LUTS) attributed to benign prostatic hyperplasia (LUTS/BPH) assessing a 12-week remote exercise intervention versus health education control.
