Abstract
Introduction:
To compare percutaneous nephrolithotomy (PCNL) outcomes between the elderly and young age groups and examined differences between young-old, old-old, and oldest-old patients.
Methods:
A retrospective analysis was conducted on 8191 renal units that underwent PCNL between September 1997 and March 2020 at three Turkish academic institutions. Patients were classified into young (18–64 years) and elderly (65+ years) age groups. The elderly age group was classified into young-old (65–69 years), old-old (70–79 years), and oldest-old (80+ years). Demographics, stone features, and perioperative and postoperative outcomes were compared between groups. The factors affecting stone-free rates and complications were determined in the elderly age group.
Results:
The patients' median age was 47 years (18–100) and the female to male ratio was 1:1.72. The stone-free and complication rates were 78.9% and 16.4%, respectively. General complications, blood transfusion, postoperative urinary tract infections, and major complications rate were similar between the young and elderly age groups (P = .902, P = .740, P = .659, P = .219, respectively). The stone-free rate was higher in the elderly age group (P = .002). Presence of partial or complete staghorn stones and number of stones were independently associated with stone-free rates for elderly age group patients (P = .006, P < .001, respectively). Stone burden (≥400 mm2) and presence of partial or complete staghorn stones were significantly associated with complications for the elderly age group patients (P = .038, P = .014, respectively).
Conclusions:
In the young-old, old-old, and oldest-old age group, PCNL appears like the preferred treatment with high stone-free rates but similar complication rates compared to their younger counterpart.
