Purpose
This study examined the prevalence of risk factors for urological stone surgery and their possible influence on outcome and complications following ureteroscopy (URS).
Methods
The Clinical Research Office of the Endourological Society Ureteroscopy Global Study collected prospective data on consecutive patients with urinary stones treated with URS at centers around the world for 1 year. The prevalence of common comorbidities and anticoagulation therapy and their relationship with complications and age were examined.
Results
Of 11,719 patients, 2,989 patients (25.8 %) had cardiovascular disease, including 22.6 % with hypertension, and 1,266 patients (10.9 %) had diabetes mellitus. Approximately six percent of patients were receiving oral anticoagulation therapy, including aspirin (3.7 %) and clopidogrel (0.8 %). The prevalence of hypertension and diabetes mellitus and the proportion of patients receiving anticoagulant medication and/or antidiabetes treatment increased with age. Elderly were more likely to develop a postoperative complication when they had diabetes, a cardiovascular disease or received anticoagulation therapy. Post-operative bleeding was higher in patients receiving anticoagulants than those not receiving them (1.1 vs. 0.4 %; p < 0.01). Patients with risk factors for stone formation had more complications than those without (4.9 vs. 3.0 %, p < 0.001).
Conclusions
This is the first study confirming in a global population that URS can effectively and safely be performed in a population with high comorbidity. The risk of a complication was highest among elderly patients presenting with comorbidities.
