WMT for Multidrug-Resistant Organism UTI
Sponsor: The Second Hospital of Nanjing Medical University
Summary
This is a single-center, prospective, single-arm, exploratory clinical study to evaluate the efficacy, safety, and potential mechanisms of washed microbiota transplantation (WMT) in patients with recurrent urinary tract infections caused by multidrug-resistant organisms (MDRO-UTI). With increasing antimicrobial resistance, MDRO UTI becomes refractory and poses a significant therapeutic challenge. WMT may reconstruct gut microbiota, reduce uropathogen colonization, decrease antibiotic resistance gene burden, and modulate host immunity and metabolism. Approximately 10 eligible patients will receive WMT delivered via colonic transendoscopic enteral tubing (TET) for 3 times according to the Nanjing Consensus on Washed Microbiota Transplantation. Participants will be followed for up to 12 months with clinical, microbiological, metagenomic, metabolomic, and immunological assessments.

Washed Microbiota Transplantation (WMT)
Participants will receive washed microbiota transplantation delivered via colonic transendoscopic enteral tubing (TET) for 3 times. The WMT preparation follows the Nanjing Consensus on Washed Microbiota Transplantation (Chin Med J, 2020). Donor fecal material is obtained from healthy screened donors and processed using the GenFMTer intelligent separation system with repeated washing and quality control. The final microbiota suspension is transplanted into the colon through an indwelling TET tube.
