Benign prostate hypertrophy (BPH) and inflammation are common non-cancerous enlargement of the prostate, which result in urinary interference and incomplete drainage of the bladder. Compression of the urethra is common cause of such resistance of full draining, and may over time result in progressive hypertrophy, instability, urgency, nocturia and weakness of the bladder musculature.
Prostatic growth frequently begins in the 30s, and it is estimated that 50% of all males have benign enlargement leading to 75% by age 80. BPH and low grade inflammation is one of the ten most prominent and costly disorders in males over 50.
Urinary tract symptoms are divided into issues of storage, voiding, and post-void symptoms can be associated with bladder outlet obstruction (BOO).
This study utilizes isolation of adipose-derived stem/stromal cellular stromal vascular fraction (AD-cSVF) deployed as an IV suspension in sterile Normal Saline (500cc). Due to the anti-inflammatory and immunomodulatory effects common to AD-cSVF are tested in relief of the inflammatory elements and the concurrent hypertrophy in BPH. Early pilot use has suggested a positive effect on these issues, and have relieved much of the incomplete voiding, pain, nocturia, delay in starting/stopping urination, and increased urgency and frequency.
Lipoharvesting of Adipose-Derived tissue stromal vascular fraction (AD-tSVF) is now a common closed access to subdermal adipose stromal/stem cell population consisting of both stem and stromal cells, each of which are felt to contribute a wide variety of effects and potentials. Closed, sterile isolation of the AD-cSVF is possible with advent of closed systems to enzymatically release these cells from the actual matrix (scaffolding) within the adipose tissue complex (ATC). This group of largely un-designated cell population is isolated and concentrated via a standard gradient layer separation by centrifugation. This cellular isolate is then suspended in an IV of 500 cc Normal Saline and reintroduced to the patient.
This study is examining the clinical safety and efficacy of this approach, as well as tracking the duration of effects and establish a therapeutic interval.

Prostatic growth frequently begins in the 30s, and it is estimated that 50% of all males have benign enlargement leading to 75% by age 80. BPH and low grade inflammation is one of the ten most prominent and costly disorders in males over 50. BPH is often a progressive disease and may lead to increased urinary stasis and increased risk of urinary tract infections.
Urinary tract symptoms are divided into issues of storage, voiding, and post-void symptoms can be associated with bladder outlet obstruction (BOO). Storage symptoms include need to urinate frequently, waking at night to urinate (nocturia), and incontinence (involuntary). Voiding issues include urinary hesitancy, intermittency (start/stopping flow), leaking after voiding and may include some pain (dysuria) associated with urination. Post-voiding symptoms include abdominal pain, feeling of full bladder, acute urinary retention and frequency, dysuria, hesitancy, etc.
Causation may be associated with age related changes in androgens (such as testosterone and others), but do not seem to be the direct cause of the enlargement.
Androgens promote prostate cell proliferation, but relatively low levels of testosterone are often found in patients with BPH.
Treatment often has been aimed at lifestyle change (exercise, decrease nighttime fluid intake, moderating alcohol and caffeine, decrease certain anticholinergic medications. Use of medication have some advantages, including alpha blocker and 5 alpha-reductase inhibitors, and some broad spectrum antibiotics (like Ciprofloxacin) seem to help many of those with increasing symptoms. Self catheterization and surgery are occasionally needed for patient comfort and reduction of symptomatology.
Alternative remedies include herbal remedies (saw palmetto) and anecdotal effects in patients receiving parenteral stem/stromal cell therapies for other clinical issues. Initially commented that the patient reported improvement of symptoms, have led to this study to determine if any long-interval therapy may be as effective as surgery or catheterization.

Exclusion Criteria:
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
Malignancy means cancer. Criteria about another or earlier malignancy ask whether you have had a different cancer, usually within a set number of years.
Some are commonly allowed, such as treated skin cancers other than melanoma and early cancers removed completely — check the exceptions this study lists.
A biopsy takes a small piece of tissue to examine. “Archival tissue” is a sample already taken, for example at diagnosis, and kept by the hospital.
Whether a stored sample will do depends on when it was taken, how much there is and what the study needs. Ask whether the study accepts your stored sample or needs a new biopsy.
