| Summary: | Abstract Background This study investigates the association between urolithiasis-induced hydronephrosis and the reactivation of herpes zoster (HZ). Methods This retrospective cohort study utilized data from the TriNetX database. Participants aged ≥ 20 years with a newly diagnosis of “calculus of kidney with calculus of ureter” between 2011 and 2022 were included. The cohort was divided into two groups: those with (case) and without (control) “hydronephrosis with renal and ureter calculus obstruction.” The primary endpoint was the diagnosis of HZ within 1- and 2-year post-index date, comparing outcomes between the case and control groups. Propensity score matching was applied to create a 1:1 matched cohort. Risk ratios and odds ratios were calculated to evaluate the association between exposure and outcome. Results Before matching, there were 40,615 participants in the case group and 68,085 in the control group. After propensity score matching, the cohorts were balanced, with 38,100 participants in each group. Compared to patients without hydronephrosis, those with hydronephrosis had a higher risk of HZ, with risk ratios and odds ratios of 1.585 and 1.588 within 1 year, and 1.305 and 1.308 within 2 years, respectively. Conclusions A significant association between calculus-induced obstructive hydronephrosis and increased HZ incidence, with particularly elevated risk observed during the first year following diagnosis. These findings suggest the importance of monitoring for HZ in patients with obstructive uropathy. |
