Objective: To define predictors for initial retrograde ureteral stenting (RUS) failure with the need for the percutaneous nephrostomy (PCN) insertion as a drainage method in patients with complicated acute calculus obstructive uropathy. Methods: We undertook a retrospective evaluation of patients who presented with complicated obstructive calculus uropathy (acute renal failure or obstructive pyelonephritis) between January 2016 and January 2020. Patients in whom there was failure to visualize ipsilateral ureteric orifice and those with extrinsic ureteral obstruction were excluded. Patient demographics and radiological data including stone site, hydronephrosis grade, maximum transverse stone diameter, periureteral density (PUD) and pericalcular ureteric thickness (P-CUT) at the maximum transverse stone diameter were assessed using non-contrast computed tomography at the time of admission. Results: The study included 256 patients who were managed initially by RUS trial. Of them, 48 (18.8 %) had RUS failure. The presence of acute pyelonephritis, increased maximum transverse stone diameter ≥ 9.5 mm, P-CUT ≥ 7.5 mm, and PUD at stone level ≥ 17.5 HU were risk factors associated with RUS failure (P = 0.007, 0.002, < 0.001, and < 0.001, respectively). Conclusion: Initial radiological stone and ureteric characteristics, in addition to the clinical diagnosis of obstructive pyelonephritis, can be used to determine PCN insertion as the preferred option over RUS for urinary drainage.

Introduction: To evaluate therapeutic results till 5 years after therapy of obstructive pyelonephritis (OPN) emphasizing regular follow-up. Material and Methods: During 5 years, 57 patients with OPN were treated. The patients' charts were reviewed retrospectively for clinical data. These were completed by a questionnaire. Results: In the group of 57 patients (average age 56 years), about two third were women. Urolithiasis (65%) and tumors (21%) were the main causes of obstruction; fever (91%) and loin pain (86%) the main symptoms. Three fourth of the patients showed renal insufficiency and nearly 50% anemia. E. coli and Proteus spp. were the dominating organisms. Sonography detected obstruction in 93% cases. In one third of cases, CT scan was added; 81% percutaneous nephrostomy and 19% ureteral stenting were the initial methods of urinary drainage. During therapy, 23% nephrectomies (19% complete, 4% partial) were performed. Long-term follow-up showed 11% recurrent OPN and 33% recurrent UTI. Conclusions: After diagnosis of OPN, primary nephrostomy or ureteral stenting and antibiotic therapy are the first measures. If recurrent urinary tract infections or OPN occur, long-term follow-up and low-dose antibiotic prophylaxis may be discussed.

AbstractAcute obstructive uropathy is associated with significant morbidity among patients with any condition that leads to urinary tract obstruction. Immediate urinary diversion is necessary to prevent further damage to the kidneys. In many centres, the two main treatment options include percutaneous nephrostomy (PCN) and retrograde ureteral stenting (RUS). The purpose of this study if to compare the efficacy and safety of PCN and RUS for the treatment of acute obstructive uropathy. We searched the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, CINAHL, EMBASE, the World Health Organisation International Clinical Trials Registry Platform and ClinicalTrials.gov. We also searched the reference lists of included studies to identify any additional trials. We included randomised controlled trials and controlled clinical trials comparing the outcomes of clinical improvement (septic parameters), hospitalisation duration, quality of life, urinary-related symptoms, failure rates, post-procedural pain [measured using a visual analogue scale (VAS)] and analgesics use. We conducted statistical analyses using random effects models and expressed the results as risk ratio (RR) and risk difference (RD) for dichotomous outcomes and mean difference (MD) for continuous outcomes, with 95% confidence intervals (CIs). Seven trials were identified that included 667 patients. Meta-analysis of the data revealed no difference in the two methods in improvement of septic parameters, quality of life, failure rates, post-procedural pain (VAS), or analgesics use. Patients receiving PCN had lower rates of haematuria and dysuria post-operatively and longer hospitalisation duration than those receiving RUS. PCN and RUS are effective for the decompression of an obstructed urinary system, with no significant difference in most outcomes. However, PCN is preferable to RUS because of its reduced impact on the patient’s post-operative quality of life due to haematuria and dysuria, although it is associated with slightly longer hospitalisation duration.

OBJECTIVES: Ezetimibe or colesevelam are often used for treating hypercholesterolemia when statin therapy is insufficient or not well tolerated. Our study objective was to examine prevalence of concomitant statin use and associated factors among hypercholesterolemia patients newly treated with ezetimibe or colesevelam. METHODS: This analysis evaluated a large health plan’s Commercial and Medicare Advantage claims data from 1/1/08 to 7/31/12. The first ezetimibe (excluding fixed combination therapy of ezetimibe/simvastatin) or colesevelam prescription fill date during this period was identified as the index date. Patients were assigned to either ezetimibe or colesevelam cohort based on the index drug and were required to have ≥ 2 consecutive prescriptions for the index drug and have at least 6 months and 12 months continuous enrollment before and after the index date, respectively. Prevalence of concomitant statin use was identified based on pharmacy claims. Patient demographics and clinical characterisitics were explored to examine the factors associated with concomitant statin use using multivariate logistic regression. RESULTS: A total of 679 colesevelam and 1439 ezetimibe patients were included in this study. The concomitant use of statins was 24% among colesevelam and 50% among ezetimibe patients, respectively. After adjustment for patient demographics and comorbidities, ezetimibe patients were 3.2 times more likely than colesevelam patients to have concomitant statin use (OR= 3.168, 95% CI: 2.573, 3.900, P<0.001). Other significant factors associated with higher concomitant statin use include: male gender (OR= 1.296, 95%: 1.079, 1.558, P=0.006), presence of diabetes mellitus (OR=1.262, 95% CI: 1.035, 1.539, P=0.021) and higher Charlson comorbidity score (OR=1.114, 95% CI: 1.046, 1.187, P<0.001) CONCLUSIONS: In this claims data analysis, statins were administered along with ezetimibe more frequently than administered with colesevelam, which should be taken into account when evaluating effectiveness of ezetimibe vs. colesevelam in the real-world treatment of hypercholesterolemia.

Background: Decision to undertake total thyroidectomy when gross inspection of the gland raises suspicion of widespread degenerative changes is often intraoperative. Knowing the factors associated with intraoperative conversion to total thyroidectomy may assist preoperative counselling. This study describes the probability of conversion to total thyroidectomy and factors associated with con-version among patients hitherto planned for partial thyroidectomy. Methods: We reviewed 191 records and extracted data on patient demographics, the pre-operative radiograph findings, the weight of excised gland and the operation performed. Descriptive and inferential statistics were performed. Receiver operator curve was used to assess for cut-off point. P-value was set at 0.05. Results: A total of 191 records was reviewed consisting of 181 females (94.8% 95% CI 90.6-97.5) and 10 males (5.2%, 95%CI 2.5-9.4). Only nodular goiters required conversion to total thyroidectomy. The over-all probability of total thyroidectomy was 11%(95% CI 7.0-16.3). The probability of total thyroidectomy in female was 10.5%(95% CI 6.4-16.9) while in male was 20%(95% CI2.5-55.6). The probability of total thyroidectomy in a female with nodular goiter was 8.1%(95% CI 4.8-13.5), compared to 28.6%(95% CI 3.7-71) in males. The risk of total thyroidectomy was associated with the weight of the excised gland. Conclusion: Only nodular goiters required intraoperative conversion to total thyroidecto-my and the probability of conversion was higher in males.
