Does aging affect the outcome of percutaneous nephrolithotomy?
To investigate whether aging affects surgical outcomes by comparing the results of two patient groups undergoing PNL: those over 60 and those under 60. A retrospective screen was made for patients undergoing conventional PNL surgery for renal stones performed in two separate centers between 2010 and 2013. 520 patients included were classified into age groups: patients aged 18-59 comprised Group-1 and those aged over 60 comprised Group-2. Those between 60-69 years (sexagenarian) were assigned to Group-2a; 70-79 years (septuagenarian) to Group-2b; and 80-89 years (octogenarian) to Group-2c. Patients' demographic characteristics (accompanying comorbidities, ASA scores, body mass indices and stone size) and perioperative values (duration of surgery and hospital stay, success and complication rates) were compared between the groups. Mean stone size was similar in groups (30.1 ± 15.5 vs. 31.5 ± 15.4 mm, p = 0.379). The mean ASA value for the patients in Group-1 was 1.61; significantly lower than that in the other groups (p = 0.000). The level of accompanying comorbidities in Group-1 was significantly lower than that of the other groups (p = 0.000). The mean duration of surgery, postoperative hematocrit drop, complication and success rate were statistically similar in Groups 1 and 2 (p = 0.860, p = 0.430, p = 0.7, and p = 0.66, respectively). The duration of hospital stay was significantly shorter in the patients in Group-1 compared to those in Group-2 (p = 0.008). In experienced hands, PNL can be safely and reliably performed in the treatment of renal stones in elderly patients.
