[Long-term blood pressure outcome after unilateral adrenalectomy for primary hyperaldosteronism]. / Contrôle à long terme de la pression artérielle après surrénalectomie pour hyperaldostéronisme primaire.

OBJECTIVES: To evaluate long-term results of adrenalectomy for primary aldosteronism (PA) and to identify prognostic factors associated. METHODS: Exhaustive retrospective review of all consecutive patients undergoing adrenalectomy for PA between 2002 and 2013 in our department. All patients underwent preoperative: clinical evaluation (age, sex, height, weight, systolic and diastolic BP under treatment, identification of anti-hypertension treatment), biological evaluation (potassium, renin, aldosterone) and radiological evaluation (CT and/or MRI). Blood pressure was assessed postoperatively at 1 month, 1 year, then at the date of the latest news. The patients were classified into three categories: cured (no antihypertensive therapy in postoperative associated with strictly lower blood pressures of 140/90mmHg), improved (decreased number of drugs or number unchanged but with better blood pressure control), and refractory (no change in the number of drug and blood pressure, or deterioration of one or other of these two parameters). RESULTS: We evaluated 43 patients, 23 men and 20 women, with a median follow-up of 74.4 months [16.8 to 141]. Pathological analysis described 34 adenomas (79%), 7 hyperplasias (16%) (5 micro-nodular and 2 macro-nodular) and 2 adrenocortical carcinoma (5%). The postoperative long-term assessment found 20% of cured patients (n=8), 65% of improved (n=26) and 15% of refractory (n=6). Prognostic factors associated with favorable long-term blood pressure outcome were those typically associated with ARS score [preoperative number of anti-hypertension drugs (P=0.005), BMI<25kg/m2 (P=0.009), and duration of hypertension (P=0.007)]. CONCLUSION: Adrenalectomy for PA is a long-term effective treatment for blood pressure control. Prognostic factors associated with long-term success are those conventionally described in ARS score. LEVEL OF EVIDENCE: 4.

[Percutaneous nephrolithotomy for kidney stones in elderly patients: Meta-analysis of results and complications]. / Néphrolithotomie percutanée des calculs rénaux des personnes âgées : méta-analyse des résultats et complications.

INTRODUCTION AND OBJECTIVE: Percutaneous nephrolithotomy (PCNL) is the gold standard treatment for kidney stones regardless of age. Elderly patients (EP)≥65years old, in growing numbers, have more comorbidities than the general population, may alter results of PCNL. The aim of this meta-analysis was to compare efficacy and complications of this procedure between EP and young patients (YP). METHODS: Original studies of prospective and historical cohorts, in English or French, presenting PCNL series published on PubMed until 2015 were identified using the keywords percutaneous nephrolithotomy, elderly patients, kidney stones and staghorn calculi. Our analysis focused on therapeutic efficacy, defined by absence of residual fragment or the presence of residual fragments<4mm at 3 postoperative months, and postoperative complications according to patient age: YP<65 years old and EP≥65 years old. Binary qualitative data were analyzed using odds ratio (OR) and quantitative data by estimating the difference of means. RESULTS: In total 397 studies were identified among which 23 were checked and 8 included in the meta-analysis for methodological quality corresponding to 4995 YP and 820 EP. No efficacy difference (OR=0.96; [IC95 %: 0.80; 1.17]; P=0.71), operating time (+1.15min in EP [IC95 %: -2.83; 5.12]; P=0.57) and average length of stay (+0.29 days in EP [IC95 %: -0.14; 0.72]; P=0.19) has been reported. It was a trend to more urinary infections (OR=2.24; [IC95 %: 0.74-6.80]; P=0.16) and a significantly increase of postoperative blood transfusions in EP (OR=1.41; [IC95 %: 1.00-1.97]; P=0.04). CONCLUSIONS: PCNL for kidney stones n EP is effective with a significantly increase the risk of postoperative blood transfusions compared to YP.
