“…Bagrodia et al [10] in USA and El-Assmy et al [11] in Egypt also found no significant differences among groups with respect to stone-free and complication rates, operative time, length of hospital stay, or need for multiple accesses. Stone-free rate and complication rates were found to be independent of BMI by Tomaszewski et al [12] and Pearle et al [13] On the other hand there are reports of longer operative time, poorer stone clearance, and increase risk of postoperative complications in obese patients undergoing PCNL. Faerber and Goh found a longer hospital stay (3.5 days vs. 4.4 days) and a higher rate of complications (16% vs. 37%) in the morbidly obese group than the normal weight group.…”

Objective: To compare the effect of body mass index (BMI) on operative time, hospital stay, stone clearance, postoperative complications, and postoperative analgesic requirement in patients undergoing percutaneous nephrolithotomy (PCNL) by comparing three BMI groups. Material and methods:This is a retrospective analysis of 129 patients who underwent PCNL from January 2010 to August 2013. All the patients underwent PCNL by a standard technique. The patients were divided into three groups: patients having a BMI ≤24 kg/m 2 were included in the normal group, those having a BMI of 24.1-30.0 kg/m 2 were included in the overweight group, and those having a BMI >30 kg/m 2 were included in the obese group. Three groups were compared for operative time, hospital stay, stone clearance, postoperative complications, and postoperative analgesic requirement.Results: A total of 129 patients including 44 females and 85 males were included with a mean age of 45.00±1.44 years. The mean age in the normal group was 43.29±1.69 years, 47.08±1.29 years in the overweight group, and 43.61±1.25 years in the obese group. The mean stone size in the normal group was 25.46±8.92 mm, 28.01±8.40 mm in the overweight group, and 26.84±7.41 mm in the obese group. Our results showed no statistically significant difference with respect to mean operative time, mean hospital stay, and stone clearance in the normal, obese, and overweight patients undergoing PCNL. Postoperative complications and analgesia requirement were also similar in all the three groups. Conclusion:There was no effect of BMI on operative time, hospital stay, stone clearance, postoperative complications, and postoperative analgesic requirement in patients undergoing PCNL. PCNL is a safe and effective procedure for the removal of renal stones in obese patients.

“…The important factors in increasing anesthesia and procedural time in the patient with a higher BMI may be more difficult in intubation, resulting in a longer time to access the kidney, displacement of the Amplatz sheath during the procedure, and time wasted to correct its location. Other studies did not show any differences [16,17,19].…”

“…So, BMI was not an effective parameter in stone-free rates in PCNL. In other studies that compared the effect of BMI in prone PCNL, stone-free rates were similar in patients with different BMIs [16][17][18][19]. The patients with more than a 5 mm residual stone were scheduled for ESWL or secondlook PCNL.…”

KEYWORDS: Complete supine PCNL, prone PCNL, BMI, stone-free rate, fever, total ultrasonic guidance CORRESPONDENCE: Siavash Falahatkar, Professor Introduction: To determine whether body mass index (BMI) can influence the outcomes of percutaneous nephrolithotripsy (PCNL) in the prone and the supine position or cannot. Materials and Methods:We have reviewed the files of 110 patients who underwent the prone and the complete supine PCNL (csPCNL) between September 2007 and December 2008 in the 3 categories: BMI < 25, 25 > BMI < 30, and BMI > 30. Results:The demographic data and surgical outcomes of the patients were evaluated. There was no statistically significant difference between groups, except the stone-free rate in the BMI < 25 group, which was higher in the prone position. Moreover, in groups with higher BMIs, the anesthesia time was increased. The overall stone-free rate was 78 and 73.3% in the prone and supine positions, respectively (p = 0.57). No statistically significant differences were found, except a higher incidence of fever in the prone approach and a significantly shorter anesthesia time in the complete supine position. Conclusion:The outcomes of PCNL in both positions were not dependent on the patient's BMI. Also, the anesthesia time was prolonged in patients with a higher BMI. This study showed that the prone and the supine PCNL in obese and morbidly obese patients were safe and effective. UroToday International Journal ® UI J

“…Pearle et al showed that in 57 patients with a BMI of >30 kg/m 2 the operative time was slightly longer but outcomes in terms of stone-free and complication rates were not different compared to 179 patients with a BMI of <30 kg/m 2 [14].…”

Percutaneous nephrolithotomy (PNL) is a safe and effective procedure in the treatment of large renal stones in obese and non-obese patients with low rate of morbidity and high success rate in different groups of body mass index (BMI), some surgeons believe that morbid obesity increases the risk of complications of PNL, but different recent studies showed there were no significant differences. Objective: To analyze the outcomes of PNL in patients with different BMI and to assess the effects of obesity in the result of PNL in terms of efficacy & safety regarding total operative time, blood transfusion, organ injury, stone clearance, hospital stay, and the need of auxiliary procedures.
