Purpose. To evaluate the safety and efficacy of RIRS for the treatment of multiple unilateral intrarenal stones smaller than 20 mm.Methods. Between March 2007 and April 2013, patients with multiple intrarenal stones smaller than 20 mm were treated with RIRS and evaluated retrospectively. Each patient was evaluated for stone number, stone burden (cumulative stone length), operative time, SFRs, and complications.Results. 173 intrarenal stones in 48 patients were included. Mean age, mean number of stones per patient, mean stone burden, and mean operative time were40.2±10.9years (23–63),3.6±3.0(2–18),22.2±8.4 mm (12–45), and60.3±22.0minutes (30–130), respectively. The overall SFR was 91.7%. SFRs for patients with a stone burden less and greater than 20 mm were 100% (23/23) and 84% (21/25), respectively (χ2=26.022,P<0.001). Complications occurred in six (12.5%–6/48) patients, including urinary tract infection or high-grade fever >38.5°C in three cases, prolonged hematuria in two cases, and ureteral perforation in one case, all of whom were treated conservatively. No major complications occurred.Conclusions. RIRS is an effective treatment option in patients with multiple unilateral intrarenal stones especially when the total stone burden is less than 20 mm.

Objective: Aim of the present study was to evaluate the safety and efficacy of Percutaneous Nephrolithotomy (PCNL) in the Galdakao- Modified Supine Valdivia (GMSV) position in order to predict operative time, stone-free rate and onset of complications taking into account comorbidity, stone-related parameters and anatomic upper urinary tract abnormalities. Material and methods: A prospective evaluation of patients who underwent to PCNL in GMSV position for renal stones &gt; 2 cm, from January 2009 to February 2015 was performed. According to the technique, upper urinary tract abnormalities, stone chemical and morphological characteristics, and patients' history were matched with operative outcome, in terms of stone-free, intervention time and incidence of perioperative complications. Results: Seventy-two cases were collected; mean operative time was 105 minutes (DS 41): staghorn stones and the presence of comorbidity resulted statistically significant variables. The complication-rate resulted in line with data showed in literature: hyperpyrexia and hemorrhage were the more frequently complications found. The overall stone-free was reached in 48 patients (67%), and it was influenced by patients’ anatomic abnormalities. Conclusions: In the treatment of renal stones, PCNL may be a safe and effective choice; nevertheless, patients’ anatomic abnormalities or staghorn-stones may influence the outcomes. Thus, a prospective study with a larger population is needed to verify our outcomes.

Study Design: Retrospective cohort study. Objective: To determine the effects of operative time on postoperative complications in patients age 65 and older undergoing posterior lumbar fusion. Methods: All patients age 65 and older undergoing posterior lumbar fusion were identified in the 2012 to 2015 American College of Surgeons National Surgical Quality Improvement Program database. The primary outcome measures were complications occurring up to 30 days postoperatively, including death, any complication, and complication subtypes. The primary independent variable was operative duration. Both bivariate and multivariate analyses utilized logistic regression and analyzed operative duration as a continuous variable. Statistical significance was considered P < .05. Results: A total of 4947 patients age 65 and older undergoing posterior lumbar fusion were identified. The mean operative time was 3.3 hours (SD 1.7). The overall complication rate was 13.4% (n = 665). In multivariate analysis, each incremental hour of operative time was associated with increased risk of postoperative thromboembolism (odds ratio [OR] = 1.23; 95% confidence interval [CI] = 1.10-1.37), transfusion (OR= 1.25; 95% CI = 1.18-1.32), urinary tract infection (OR = 1.21; 95% CI = 1.10-1.32), and total postoperative complications (OR = 1.22; 95% CI = 1.16-1.27). Conclusion: For patients age 65 and older undergoing posterior lumbar fusion, longer operative time is associated with greater risk for thromboembolism, transfusion, intubation, kidney injury, urinary tract infection, surgical site infection, and overall postoperative complications. This data highlights several specific complications that are influenced by operative time in older patients, and further supports the need for future protocols that seek to safely minimize operative time for posterior lumbar fusion.

Left Flank Pain

Emphysematous pyelonephritis (EPN) is a life-threatening bacterialinfection and should be treated rapidly and carefully. We reporta case of EPN with complete duplication of the left urinary tract.A 68-year-old woman was admitted to our hospital complainingof high-grade fever and left flank pain. An abdominal computedtomography scan showed gas was presented in the renal parenchyma,not only the pelvis and ureter. Based on these findings,a diagnosis of left EPN was made. A partial nephrectomy of theaffected left upper pole moiety was performed and the patientunderwent additional medical management. Other 83 cases ofEPN from the Japanese literature were reviewed.
