Percutaneous nephrolithotomy is safe and effective in aging male patients: a single center experience

Abstract

Objective To assess the safety and effectiveness of percutaneous nephrolithotomy in aging male patients. Methods Two hundred eighty-three male patients over the years of forty undergoing percutaneous nephrolithotomy between December 2009 and September 2014 were evaluated, retrospectively. The patients were stratified by four age groups [40–49 (group-1), 50–59 (group-2), 60–69 (group-3), ≥70 years (group-4)]. The groups were compared regarding stone size, mean operation time, mean access number, mean nephrostomy removal time, hospitalization duration, stone-free rate, and complications rate. The patients were also evaluated with regard to glomerular filtration rate levels preoperatively and in the sixth month after surgery. Results Mean stone size was 810 ± 490 mm2 in group-1, 840 ± 500 mm2 in group-2, 845 ± 480 mm2 in group-3, and 800 ± 460 mm2 in group-4 (p = .02). There was no statistical difference between the four groups in terms of mean operation time, access number, hemorrhage, nephrostomy removal time, and hospital stay duration (p > .05). After additional interventions; no significant difference was detected for final stone-free rates among the groups (p = .12). A significant improvement was detected in glomerular filtration rate levels in the sixth month after surgery in all groups (p < .05). Conclusion These results indicate that percutaneous nephrolithotomy is a safe and effective method in aging male patients.
