Does aging affect the outcome of percutaneous nephrolithotomy?

Area of Science:

• Urology
• Geriatric Surgery

Background:

• Aging is associated with increased comorbidities and potentially altered surgical outcomes.
• Percutaneous nephrolithotomy (PNL) is a standard treatment for large kidney stones.

Purpose of the Study:

• To compare surgical outcomes of PNL in patients over 60 versus those under 60.
• To determine if age impacts the safety and efficacy of PNL for renal stones.

Main Methods:

• Retrospective analysis of 520 patients undergoing PNL for renal stones (2010-2013).
• Patients were divided into two groups: Group-1 (18-59 years) and Group-2 (over 60 years).
• Demographic data, comorbidities, ASA scores, stone size, operative time, hospital stay, and complication/success rates were compared.

Main Results:

• Stone size and mean operative duration were similar between groups.
• Patients over 60 had higher ASA scores and more comorbidities.
• Complication and success rates were comparable; younger patients had shorter hospital stays.

Conclusions:

• PNL is a safe and effective treatment for renal stones in elderly patients.
• While older patients may have more comorbidities, PNL outcomes are not significantly worse.
• Experienced surgeons can achieve good results in elderly patients undergoing PNL.
