- Impact of Obesity on Outcomes of Supine Percutaneous Nephrolithotomy(2020) FERREIRA, Thiago Augusto Cunha; DUTRA, Matheus Marques Guerra; VICENTINI, Fabio Carvalho; SZWARC, Marcelo; MOTA, Priscila Kuriki Vieira; EISNER, Brian; MURTA, Claudio Bovolenta; CLARO, Joaquim Francisco de AlmeidaObjectives:To determine whether obesity has an impact on the outcomes of supine percutaneous nephrolithotomy (PCNL). Patients and Methods:We retrospectively evaluated a prospectively created database of patients who underwent PCNL in the supine position from June 2009 to June 2014. The patients were divided into two groups according to their body mass index (BMI): <30 kg/m(2)(group 1, nonobese) and >= 30 kg/m(2)(group 2, obese). Pre, peri, and postoperative data were analyzed. Stone complexity was classified according to Guy's stone score. The primary endpoint was the absence of stone fragments of >= 4 mm on CT scans at postoperative day 1. Complications were graded according to the modified Clavien classification. Results:Of the 401 patients, 307 (76.6%) were nonobese and 94 (23.4%) were obese. Regarding demographic and stone characteristics, group 2 (BMI >= 30 kg/m(2)) had a higher percentage of female patients (67.3%vs50.4%,p = 0.002) and a higher mean BMI (34.8vs24.5 kg/m(2),p < 0.001) than group 1. Success rates were not statistically different between the groups (group 1 = 61.8%, group 2 = 51%,p = 0.08). There were no differences in the transfusion rate (group 1 = 2.9%, group 2 = 4.2%,p = NS) or total number of complications greater than Clavien grade 1 (group 1 = 13.6%, group 2 = 13.8%,p = NS). Conclusion:In a retrospective study of 400 patients undergoing PCNL, the outcomes were not different between nonobese and obese patients. To our knowledge, this is the first study evaluating these outcomes for PCNL performed in the supine position. Further multicenter and prospective studies are necessary to verify these findings.
