Objective: To evaluate the operative and postoperative outcomes in patients >70 years of age who underwent PNL and to compare them with a younger group.
Material and Methods: We retrospectively evaluated 508 patient data who underwent con- ventional PNL for >2 cm kidney stones in our institution between 2016 and 2019. The patients were divided in to two group according to their age. Group 1 consisted with patient whose age is younger than 70 years and Group 2 consisted with patient whose age is equal or higher than 70 years. Patients’ comorbidities, ASA scores, body mass indices (BMI), stone size and perioperative values such as surgery time, fluoroscopy time, complica- tion rates, length of hospital stay and stone-free rates were compared between the groups.
Results: 476 patients were identified in Group 1 (younger), and 32 patients were in Group 2 (elderly). The mean age in elderly patients was 73 years (range 70-86) and 48 years (range 18- 69) in younger group. There is no difference in multiple stone rate, operation time, fluoroscopy time, length of hospital stay, the levels of stone free rate and complication rates between groups. Preoperative stone size, staghorn stone rate, and transfusion rate was significantly higher in elder- ly patients than younger group (respectively; p = 0.027, 0.009, 0.003).
Conclusion: PNL had acceptable results for large kidney stones and was safe in elderly patients. Keywords: Elderly, kidney stone; nephroli-
thotomy; percutaneous; safety
