Therapeutic efficacy and short-term durability of trans-urethral amniotic bladder injections for the treatment of refractory COVID-associated cystitis.

Introduction: COVID-19-associated cystitis (CAC) may arise following a COVID-19 infection and is characterized by the development of novel or worsening overactive bladder (OAB). CAC is possibly associated with bladder mucosal damage and the release of pro-inflammatory cytokines, resulting in inflammation and fibrosis of the bladder wall. Amniotic membrane (AM) has been shown to possess anti-inflammatory and anti-fibrotic properties and might potentially be beneficial for CAC.

Amniotic bladder therapy: six-month follow up treating interstitial cystitis/bladder pain syndrome.

Introduction: Interstitial cystitis/bladder pain syndrome (IC/BPS) is characterized by chronic pelvic pain and usually accompanies lower urinary tract symptoms. We have previously reported that amniotic bladder therapy (ABT) provides symptomatic improvement in refractory IC/BPS patients for up to 3 months. Herein, we evaluated the durability of ABT up to 6 months.

Treatment of chronic post-radiation cystitis with trans-urethral amniotic bladder therapy appears durable at 9 months: A clinical study.

Purpose: Chronic radiation cystitis (CRC) develops after radiation therapy and can present with symptoms like urinary frequency, urgency, pelvic pain, and nocturia. We have previously reported that amniotic bladder therapy (ABT) provides symptomatic improvement in refractory CRC patients for up to 3 months. Herein, we evaluated the durability of ABT up to 6 months.

A Novel Interaction between Chemokine and Phosphoinositide Signaling in Metastatic Prostate Cancer.

Prostate cancer commonly metastasizes to bone due to its favorable microenvironment for cell growth and survival. Currently, the standard of care for metastatic prostate cancer is medical castration in conjunction with chemotherapeutic agents and newer anti-androgen/androgen receptor therapies. While these therapies aim to improve the quality of life in patients with advanced disease, resistance to these therapies is inevitable prompting the development of newer therapies to contain disease progression.

Can MRI Help Inform Which Men With a History of Multifocal High-Grade Prostatic Intraepithelial Neoplasia or Atypical Small Acinar Proliferation Remain at an Elevated Risk for Clinically Significant Prostate Cancer?

Purpose: We investigated the association of MRI findings in men with a previous diagnosis of atypical small acinar proliferation (ASAP) or multifocal high-grade intraepithelial neoplasia (HGPIN) with pathologic findings on repeat biopsy.

Materials And Methods: We retrospectively reviewed patients with ASAP/multifocal HGPIN undergoing a repeat biopsy in the Michigan Urological Surgery Improvement Collaborative registry. We included men with and without an MRI after the index biopsy demonstrating ASAP/multifocal HGPIN but before the repeat biopsy.

A preliminary report assessing the feasibility and effectiveness of amniotic bladder therapy in patients with chronic radiation cystitis.

Introduction: Chronic radiation cystitis (CRC) can develop between 6 months and 20 years after radiation therapy that presents with symptoms of urinary frequency, urgency, bladder pain, and nocturia. Amniotic membrane (AM) is known to contain pro-regenerative properties and could thereby be a potential therapeutic modality for radiation-induced tissue injury of the bladder.

Materials And Methods: CRC patients recalcitrant to previous treatments received amniotic bladder therapy (ABT) comprised of intra-detrusor injections of 100 mg micronized AM (Clarix Flo) diluted in 10 mL 0.

Early three-month report of amniotic bladder therapy in patients with interstitial cystitis/bladder pain syndrome.

Background: Interstitial cystitis/bladder pain syndrome (IC/BPS) is characterized by symptomatic frequency and urgency, as well as chronic pelvic pain. Disruption of the urothelial barrier is closely associated with IC/BPS. As amniotic membranes (AM) offer capabilities of wound healing in many other fields of medicine, likewise amniotic bladder therapy (ABT) may offer capability of urothelial healing in IC/BPS.
