In my Urological Biomechanics Laboratory, we conduct regenerative medicine, tissue engineering and device development research aimed at improving the health of individuals with pelvic floor dysfunction, including urinary and fecal incontinence and pelvic organ prolapse. We have developed devices for wireless catheter-free monitoring of bladder and colon function and dysfunction, and are conducting studies to validate and improve them. These devices can be utilized to better understand the neural control of the bladder and colon and to enable closed loop neuromodulation of these organ systems.

We also test cellular and noncellular methods of regenerating nerves, muscles and connective tissue that are damaged during childbirth and other polytraumatic injuries to the pelvic region. These regenerative therapies include stem cells, secretions of stem cells, electrical stimulation, and elastogenic nanoparticles. We have several patents and patent applications, and we are continuously working with corporate colleagues to license and translate this research to improve the diagnosis and treatment of these common pelvic floor disorders.

Lay Summary

We use such tools as wireless communication and integrated circuit design to improve treatments for conditions that are common among the elderly, including stress urinary incontinence (leakage of urine), fecal incontinence (leakage of stool), and pelvic organ prolapse (the genitourinary organs fall out of position in the pelvic region). We are also investigating potential treatments to regrow/renew damaged pelvic tissue, including nerves, muscles, and the connective tissue between organs, with the goal of curing these common problems.

Medication to Strengthen, Grow Muscles Shows Promise for Treating Stress Urinary Incontinence

Bimagrumab, a novel monoclonal antibody that enlarges muscle cells and builds muscle strength, has shown promise as a potential treatment for stress urinary incontinence (SUI). It’s the first muscle growth promoter to be studied for increasing urethral pressure and continence in an SUI model.

The UroMonitor Takes Monitoring Out of the Clinic

Created and developed by researchers in the Department of Biomedical Engineering, a wireless, insertable pressure sensor to assist in the diagnosis of urinary incontinence is now one step closer to clinical application. The team is actively recruiting patients for a trial that will begin in early 2020.

The Potential Regenerative Power of Mesenchymal Stem Cells for Ischemic Kidney Injury

Prolonged interruption of renal blood supply from renal artery clamping during partial nephrectomy, followed by reperfusion, can cause tissue injury and necrosis, resulting in organ dysfunction and chronic kidney disease. Effective therapies for renal ischemia-reperfusion injury (IRI) are lacking and urgently needed.
