There were 64 (40.8%) and 93 (59.2%) patients with and without associated PD, respectively. Disease recurrence rate was 43.9% in our overall cohort through the course of follow\u2010up.

The overall post\u2010operative complication rate among surgically treated patients was 31.1%, and the presence of bilobar stones was found to be independently associated with higher odds of post\u2010operative complications (odds ratio 3.51, 95% CI 1.26\u20139.81, <jats:italic>P<\/jats:italic> = 0.017).<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>Surgical treatment is associated with decreased recurrence risk in RPC, but with significant post\u2010operative morbidity.
