WMT for Recurrent Urinary Tract Infections (WMT-rUTI)
A Prospective, Single-Center, Single-Arm Clinical Study of Washed Microbiota Transplantation for Recurrent Urinary Tract Infections
연구 개요
상세 설명
This study evaluates WMT as an interventional treatment for rUTI. WMT preparation follows the Nanjing Consensus on Washed Microbiota Transplantation (Chin Med J, 2020). Donor stool is obtained from healthy screened donors and processed using the GenFMTer intelligent fecal microbiota separation system with repeated washing and strict quality control.
Patients will receive WMT via mid-gut TET or colonic TET for 2-3 sessions. Clinical assessments include UTI episode frequency, symptom severity, antibiotic usage, and adverse events. Microbiological assessments include urine routine and clean-catch midstream urine culture during acute episodes. Fecal and urine samples will be collected at baseline (before TET placement), 3 months, and 6 months post-WMT for 16S rRNA gene high-throughput sequencing to analyze gut and urinary microbiota composition, alpha/beta diversity, and donor colonization via SourceTracker.

Participants will receive washed microbiota transplantation delivered via mid-gut transendoscopic enteral tubing (TET) or colonic TET for 2-3 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 mid-gut or colon through an indwelling TET tube.
