- Percutaneous nephrolithotomy in patients with spinal cord injury: should all these patients be automatically assigned a Guy's stone score of 4?(2021) TORRICELLI, Fabio C. M.; VICENTINI, Fabio C.; ZANETTI, Lucas; PERRELLA, Rodrigo; MARCHINI, Giovanni S.; DANILOVIC, Alexandre; BATAGELLO, Carlos A.; MURTA, Claudio B.; CLARO, Joaquim F. A.; SROUGI, Miguel; NAHAS, William C.; MAZZUCCHI, EduardoPurpose To assess the complication and stone-free rates of PCNL in patients with spinal cord injury (SCI) and to evaluate whether this population should be assigned a Guy's stone score (GSS) of 4. Methods A case-control study was conducted, and electronic charts were reviewed to search for patients with SCI, bladder dysfunction, and kidney stones who had undergone PCNL. Control cases were randomly selected from among patients with complete staghorn calculus (GSS = 4). Results One hundred and seventeen patients were included. Patients with SCI had a significant shorter operative time (119 vs. 141 min;p = 0.018). There were no significant differences between the groups in terms of the patients' position, number of renal tracts, bleeding or transfusion rate; however, there was a significantly higher complication rate (23.1% vs. 7.8%;p = 0.009) and a longer hospital stay (5.8 vs. 3.1 days;p = 0.002) among patients with SCI. With regards to the stone-free rate in patients with different grades of GSS patients with SCI who had a GSS of 1 had a stone-free rate of 85.7%, while those with a GSS of 2, 3, or 4 had 50%, 50%, and 31.5%, respectively (p = 0.024). Only patients with a GSS of 4 in the SCI group had outcomes that were similar to those of control patients (31.5% vs. 31.6%). Conclusion Patients with SCI should not be automatically assigned GSS 4. Stone-free rate is related to stone burden in these patients, although they do show a higher complication rate and a longer hospital stay than non-neurological patients.

Therefore, alternative strategies to decrease infectious complications are needed. Our aim was to evaluate the effectiveness of intrarectal povidone-iodine cleansing plus formalin disinfection of the needle tip in decreasing infectious complications after transrectal ultrasound guided prostate biopsy.Materials and Methods:We conducted a prospective, single-center, phase III trial in patients undergoing transrectal ultrasound guided prostate biopsy randomized 1:1 to rectal mucosa cleansing with gauze soaked in 10% povidone-iodine solution wrapped around the gloved index finger and needle tip disinfection by immersion in a 10% formalin solution before each puncture vs control group. The primary end point was the rate of infectious complications defined as 1 or more of the following events: fever, urinary tract infection, or sepsis.Results:Overall, 633 patients were randomized to the intervention group and 623 to the control group. The infectious complication rate was 3.9% in the intervention group and 6.4% in the control group (RR 0.61; 95% CI 0.36-0.99; P = .049). The rates of sepsis, urinary tract infection, and fever were 0.3% vs 0.5% (P = .646), 2.3% vs 4.1% (P = .071), and 1.3% vs 1.9% (P = .443), respectively. The positive urine culture rate was 5.2% in the intervention group and 9% in the control group (RR 0.57; P = .015). There was no statistically significant difference between the groups regarding the occurrence of noninfectious adverse events.Conclusions:Intrarectal povidone-iodine cleansing plus formalin disinfection of the biopsy needle tip was associated with a reduction in infectious complications after transrectal prostate biopsy.
- 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.
