Hysterectomy Versus Uterine Preservation for Pelvic Organ Prolapse Surgery
An observational study of Pelvic Organ Prolapse, run by University of Calgary at 1 site in Canada.
Trial summary
Pelvic organ prolapse (POP) is the descent of pelvic organs into the vagina resulting in bulge symptoms and occurs in approximately 50% of women. Almost 20% of women will elect surgical correction of this condition by age 85. Read more about this study

About this study
Official title: Prospective Multi-site Cohort Study Investigating Hysterectomy Versus Uterine Preservation for Pelvic Organ Prolapse Surgery: The HUPPS Study
Pelvic organ prolapse (POP) is the descent of pelvic organs into the vagina resulting in bulge symptoms and occurs in approximately 50% of women. Almost 20% of women will elect surgical correction of this condition by age 85. Removal of the uterus (hysterectomy) with concomitant vaginal vault suspension is a longstanding practice in POP surgery to address apical (uterine) prolapse. Yet, contemporary evidence on the merits of this approach relative to preservation of the uterus through suspension is needed to better inform surgical decision-making by patients and their healthcare providers. The objective of this trial is to evaluate POP-specific health outcomes and service utilization of women electing uterine suspension compared to those electing hysterectomy and vaginal vault suspension for POP surgery up to 1-year post-surgery.

Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
Contact Erin A Brennand, MD (403-944-1636, Erin.brennand@albertahealthservices.ca), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Anatomic failure to correct apical POP (time frame: 1 year). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT04890951, which also lists 1 linked publication.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
