Purpose: To assess the safety and efficacy of percutaneous nephrolithotomy
in patients more than 60 years old.
Patients and Methods: We retrospectively evaluated and compared the data of
28 percutaneous nephrolithotomies (PCNL) performed on 27 patients aged 60
years and older (mean 65.8) with the data of the remaining 178 PCNL procedu
res on 166 patients performed in our clinic between December 1997 and Decem
ber 1999,
Results: Although staghorn stones seemed to be more common in the elderly g
roup (25% v 22%), no statistical significance was demonstrated (P = 0.715),
and the stone burden was similar for the two groups (P = 0.112), The only
interesting finding in terms of patient characteristics was a significantly
higher incidence of solitary kidney in patients aged 60 years or older (29
% v 7%; P = 0.003). The success rates (stone-free patients and patients wit
h residual stones <4 mm) were similar, being 89% for the elderly group and
92% for the younger patients (P = 0.718). Transfusion rates were also simil
ar (21.4% in the elderly v 18% in the younger group; P = 0.662), No signifi
cant complication was observed in this elderly group, and no renal deterior
ation has been detected even in the follow-up of patients with a solitary k
idney.
Conclusions: Despite the somewhat higher stone burden in the elderly patien
ts (1077.92 mm(2) v 920.85 mm(2)), the stone-free rate was similar to that
obtained in the younger patients, without any higher rates of complications
or blood transfusions or longer hospital stay. Percutaneous nephrolithotom
y is a safe and effective method of stone treatment in the elderly, even if
they have a solitary kidney or complex calculi.
