Objective: the main objective is to assess whether urolithiasis diagnosed in patients with previous APRT need more endoscopic procedures to reach stone-free status and if these procedures are longer. The secondary objective is to find out if these patients have more complications resulting from endourologic procedures.
Design and methodology: we designed a case-control unicentric study including patients with upper urinary tract lithiasis treated with retrograde ureterorenoscopy (URS) between 2006 and 2022. Case patients have previous history of APRT, while controls are patients without this history. We collected epidemiological, lithiasis and treatment related information in both groups.
Results: we identified 18 upper urinary tract stones in cases that underwent endoscopic retrograde treatment. We linked these urinary stones with 18 urolithiasis diagnosed in control patients. The average age in patients and the diameter of the stones diagnosed were very similar in both groups, as well as the stones’ location. Longer surgical time was found for lithiasis treatment in case patients (129.6 versus 80.2 minutes in controls, p = 0.025). No significant differences were found regarding the rest of variables.
Limitations: this is a retrospective and observational study, and the sample size is small, so we need to expand to a multicentric study.
Originality and value: to our best knowledge this is the first study to provide data on how APRT may affect the effectiveness of endourological treatment of urolithiasis.
Conclusion: endourological procedures for treatment of upper urinary tract stones in patients with previous APRT are longer than in patients without this background.
