Our Research

Driving innovative research on pelvic organ prolapse, urinary incontinence, birth injury, and fecal incontinence.

Our group has led the transformation of Urogynecology from an empirical to a scientific approach.

John O. DeLancey, Program Co-Director

Our Approach

Our multidisciplinary group of basic scientists, clinicians, and researchers rely on a variety of methodological approaches, including:

  • Using computer modeling to study injuries to the pelvic floor that occur during childbirth
  • Using advanced magnetic resonance imaging of the pelvic floor to study the details of pelvic floor injury in women with incontinence and prolapse
  • Developing innovative technologies for improving the assessment of pelvic floor muscle strength and urethral function
  • Using the detailed information from the studies to improve the selection of patients for proper treatment

The goal of this study is to develop a computer simulation platform that allows the effects of surgical procedures to be assessed so that operative planning can be done specifically to each woman’s unique structural failure sites.  
 
Principal Investigator: Luyun Chen
This University of Michigan and Peking University Joint Institute study will determine the pelvic floor anatomical differences between Chinese and Caucasian women and enhance our understanding of the differences in both anatomy and mechanisms of prolapse between these two groups.
 
Principal Investigator: Luyun Chen
Current urodynamic testing uses 1950s technology and has not benefited from significant progress in sensor technology. This project seeks to develop new assessments that will provide physiologically relevant and accurate measures of urethral structure and function.
 
Principal Investigator: John DeLancey
LURN Logo
The purpose of this multi-site study is to develop tools and approaches to better understand the causes and clinical course of common lower urinary tract symptoms (LUTS) and how they affect women and men.
 
Principal Investigator: John DeLancey
This study will quantify the age‐related levator ani muscle and cardinal ligament length change per decade in living women and create an age‐specific pelvic floor biomechanical model to investigate aging’s contribution to the development of pelvic organ prolapse development.
 
Principal Investigator: Luyun Chen
