Traditional Chinese medicine decreases the obstructive uropathy risk in uterovaginal prolapse: A nationwide population-based study.

Traditional Chinese medicine (TCM) is a popular treatment for voiding dysfunction in Eastern countries. However, no previous studies have investigated the effects of TCM on preventing obstructive uropathy in uterovaginal prolapse women. We conducted a large-scale nationwide population-based cohort study to investigate the relationship between TCM and obstructive uropathy in uterovaginal prolapse women. This is a retrospective cohort study with the Taiwan National Health Insurance Research Database (NHIRD). The study population was newly diagnosed uterovaginal prolapse patients between 1997 and 2010 year. Among patients, 762 uterovaginal prolapse patients in this cohort. Significant adjusted HRs of urine retention or hydronephrosis in Cox proportional hazard models were uterovaginal prolapse (hazard ratio [HR]: 1.74, 95% confidence intervals [CI]: 1.43-2.14), age 40 to 64 years (1.51, 1.01-2.27), ≥60 years (3.52, 2.32-5.34), DM (1.52, 1.23-1.89), hypertension (1.38, 1.13-1.7), constipation (1.35, 1.05-1.75), urinary tract calculi (1.54, 1.06-2.23), and TCM users (0.34, 0.28-0.41). The Kaplan-Meier analysis showed a higher incidence rate of urine retention or hydronephrosis in the uterovaginal prolapse cohort compared with that of the without uterovaginal prolapse cohort. The results of this nationwide population-based study support a relationship between TCM and a reduced risk of obstructive uropathy in uterovaginal prolapse women.
