Patient's preferences: an unmet need by current urolithiasis guidelines: a systematic review

Shared decision making (SDM) in surgical specialties was demonstrated to diminish decisional regret, decisional anxiety and decisional conflict. Urolithiasis guidelines do not explicit patient preference to choose treatment. The aim of this review article was to perform a systematic evaluation of published evidence regarding SDM in urinary stone treatment.

A systematic review in accordance PRISMA checklist was conducted using the MEDLINE (PubMed) database. Inclusion criteria were studies that evaluated stone treatment preferences. Reviews, editorials, case reports and video abstracts were excluded. ROBUST checklist was used to assess quality of the studies.

188 articles were obtained. After applying the predefined selection criteria, seven articles were included for final analysis. Six out of seven studies were questionnaires that propose clinical scenarios and treatment alternatives. The last study was a patient preference trial. A general trend among included studies showed a patient preference towards the least invasive option (SWL over URS). The main reasons to choose one treatment over the other were stone-free rates, risk of complications and invasiveness.

This review provides an overview of the patients' preferences towards stone treatment in small- and medium-sized stones. There was a clear preference towards the least invasive management strategy. The main reason was less invasiveness. This is opposed to the global trends of performing more ureteroscopies and less SWL. Physicians played a pivotal role in counselling patients. SDM should be encouraged and improved. The main limitation of this study is the characteristics of the included studies.
