ABSTRACT

Objective:

We evaluated the effect of obesity on perioperative findings, postoperative success rate and complications and in the patients under going percutaneous nephrolithotomy between 2003-2013.

Material and Methods:

976 patients who underwent percutaneous nephrolithotomy in our clinic between 2003 and 2013 were included in the study. Patients were divided into three groups according to their body mass index (BMI). They were categorized as Group 1 normal (<25 kg/m2), Group 2 overweight (25-29.9 kg/m2), and Group3 obese (≥30 kg/m2). The impact of BMI was evaluated on peroperative findings (Access localization, operation time, fluoroscopy time, bleeding); postoperative outcomes (analgesic requirement, duration of nephrostomy, length of hospital stay), stone-free rates after surgery and complication rates. The outcomes of 976 patients were compared statistically.

Results:

568 male and 408 female totally 976 patients with the mean age of 47.6±10 (17-76) underwent PNL. The procedure was performed to the rightside of kidney for 536 patients and left side for 440. 420 (% 43) of the patients were normal-weight, 342 (% 35) of them were over-weighted and 214 (% 22) of them were obese. There was no significant difference between two groups when the rates of supracostal access requirement, the average operation time, mean fluoroscopy time and decline in blood count are compared (p>0,05). Average analgesic requirements, duration of hospital and nephrostomy stay were similar among all groups (p>0,05). There was no significant difference in stone-free and complication rates between two groups (p>0,05).

Conclusion:

As seen in our large series study, PNL is a highly effective and safe procedure that can be applied to the obese patients.
