  • Concomitant Renal and Urinary Bladder Allograft Transplantation Rochester, Minn.

    Patients that need reconstruction or re-building of their urinary bladder are often limited to having a segment of their intestine used for that purpose. Using intestine is less than ideal as it is an absorptive, mucous producing tissue and placing this in constant contact with urine creates significant long term problems. In patients that require a kidney transplant and bladder reconstruction, this study seeks to use a bladder graft from a deceased donor rather than intestine.

  • Effects of Testicular Torsion on Fertility Rochester, Minn.

    The purpose of this study is to examine the paternity rates of men with a history of testicular torsion.

  • Fetal Cystoscopy for Severe Lower Urinary Tract Obstruction (LUTO): A Prospective Trial (LUTO) Rochester, Minn.

    This is a pilot study to evaluate the safety, feasibility and effectiveness of fetal cystoscopy in the prenatal diagnosis and therapy of fetuses with bladder outlet obstruction. Fetal bladder outlet obstruction is a rare congenital anomaly with severe consequences to the fetus. Because of the bladder outlet obstruction, amniotic fluid is diminished, drastically leading to abnormal development of the fetal lungs. In addition, the obstruction leads to significant kidney damage, including development of end stage renal disease. Fetal vesicoamniotic shunting is the clinical therapeutic option for these fetuses. However, the shunt has many complications including blockage and dislodgement. Fetal cystoscopy has been proposed as an alternative treatment with potential advantages over the shunt by allowing the correct prenatal diagnosis and specific treatment. Initial clinical trials have demonstrated favorable outcomes. The purpose of the study is to study the outcomes of maternal and fetal patients who are undergoing fetal intervention for severe, isolated lower urinary tract obstruction (LUTO) at Mayo Clinic in Rochester, Minnesota. The objectives are to evaluate the safety, feasibility, and effectiveness of fetal cystoscopy as an experimental procedure in avoiding perinatal death and renal impairment and to compare to our clinical experience with fetal vesico-amniotic shunting.

  • Hydronephrosis Registry Rochester, Minn.

    The purpose of this research study is to contribute to an existing registry that was developed by Virginia Commonwealth University (VCU). The registry will warehouse data points for patients detected prenatally or postnatally with hydronephrosis.
