Research Summary

Dr. Kreder's clinical research focuses on two main areas of interest: overactive bladder/female incontinence, and interstitial cystitis. Within these fields of study, Dr. Kreder acts as principal or co-principal investigator on a number of clinical trials, including conventional medications and surgical treatments, as well as complimentary and alternative therapies. His work in the area of overactive bladder and female urinary incontinence encompasses the entire spectrum of treatments, including behavior and diet modifications and pelvic floor exercises, medications, or one of numerous reconstructive surgical procedures. Dr. Kreder's emphasis of study in interstitial cystitis begins with collaborations in the basic science research labs to help determine the etiology of this disease. His clinical work addresses both the reduction of symptoms through conventional therapies and alternative options, as well as the psychosocial impact of this condition on the patient.
