Meta-Analysis
Certain types of vasculitis occur more frequently and present differently in patients with familial Mediterranean fever (FMF). We assessed the characteristics of patients with FMF and systemic vasculitis through a systematic review of the literature. Medline was searched by two independent investigators until December 2017. We screened 310 articles and selected 58 of them (IgA vasculitis = 12, polyarteritis nodosa (PAN) = 25, Behçet's disease (BD) = 7, other vasculitis = 14). Clinical case reports were available for 167 patients (IgA vasculitis = 46, PAN = 61, BD = 46, other vasculitis = 14), and unavailable for 45 patients (IgA vasculitis = 38, PAN = 7). IgA vasculitis was the most common vasculitis in FMF patients with a prevalence of 2.7-7%, followed by PAN with a prevalence of 0.9-1.4%. Characteristics of FMF did not differ between patients with and without vasculitis. Patients with FMF and IgA vasculitis displayed more intussusception (8.7%) and possibly less IgA deposits on histological analysis than patients with IgA vasculitis alone. Patients with FMF and PAN had a younger age at vasculitis onset (mean age = 17.9 years), as well as more perirenal hematomas (49%) and CNS involvement (31%) than patients with PAN alone. Glomerular involvement was noted in 33% of patients diagnosed with PAN, suggesting an alternative diagnosis. Sequencing of the gene confirmed the presence of two pathogenic variants in 73% of FMF patients with IgA vasculitis or PAN. The majority of patients with BD were from one case series, and presented more skin, gastrointestinal, and CNS involvement than patients with isolated BD. In conclusion, FMF, particularly when supported by two pathogenic mutations, could predispose to IgA vasculitis, or a PAN-like vasculitis with more perirenal bleeding and CNS involvement.

Meta-Analysis Review
We aimed to perform a systematic review of randomized trials to summarize the evidence on the safety and stone-free rate after Tubeless percutaneous nephrolithotomy (PCNL) (ureteral stent/catheter, no nephrostomy) compared to Standard PCNL (nephrostomy, with/without ureteral stent/catheter) to evaluate if the tubeless approach is better. The inverse variance of the mean difference with a random effect, 95% Confidence Interval (CI), and p values was used for continuous variables. Categorical variables were assessed using Cochran-Mantel-Haenszel method with the random effect model, and reported as Risk Ratio (RR), 95% CI, and p values. Statistical significance was set at p < 0.05 and a 95% CI. 26 studies were included. Mean operative time was significantly shorter in the Tubeless group (MD-5.18 min, 95% CI - 6.56, - 3.80, p < 0.00001). Mean postoperative length of stay was also significantly shorter in the Tubeless group (MD-1.10 day, 95% CI - 1.48, - 0.71, p < 0.00001). Incidence of blood transfusion, angioembolization for bleeding control, pain score at the first postoperative day, the number of patients requiring postoperative pain medication, fever, urinary infections, sepsis, perirenal fluid collection, pleural breach, hospital readmission, and SFR did not differ between the two groups. Incidence of postoperative urinary fistula was significantly lower in the Tubeless group (RR 0.18, 95% CI 0.07, 0.47, p = 0.0005). This systematic review shows that tubeless PCNL can be safely performed and the standout benefits are shorter operative time and hospital stay, and a lower rate of postoperative urinary fistula.

Meta-Analysis Review
CONTEXT
Laparoscopic cryoablation (LCA) and percutaneous cryoablation(PCA) have been used on patients with small renal masses(SRMs) for many years. However, clinical studies assessing their feasibility and safety have reported contradictory outcomes. This systematic evaluation was performed to obtain comprehensive evidence with regard to the feasibility and safety of PCA compared with LCA.
METHODS
A systematic search of Embase, Pubmed, Medline, the Cochrane Library were performed to identify studies that compared LCA with PCA were published up to Mar 2016. Outcomes of interest included perioperative, pathologic variables, and complications.
RESULTS
Thirteen studies estimating LCA versus PCA were included for meta-analysis. Patients undergoing PCA were significantly older(WMD = -0.16 years; P = 0.01) and patients with posterior tumors were significantly prefer undergoing PCA than LCA(OR = 0.23; P = 0.0007), whereas patients with anterior tumors were significantly prefer undergoing LCA(OR = 3.82; P = 0.02). although PCA was associated with shorter hospital stay(WMD = 1.17 days; P < 0.0001) and higher incidence rate of perirenal hematoma(OR = 0.18; P < 0.0001). All the other analyzed parameters were similar, regardless of the surgical approach.
CONCLUSIONS
Patients undergoing PCA have shorter hospital stay and PCA was more frequently used in older patients and posterior tumors. Whereas LCA was associated with lower incidence rate of perirenal hematoma. Further multicenter, prospective and long-term follow-up RCTs are required to verify these findings.

Meta-Analysis
An ongoing debate concerns the need for routine placement of prophylactic intra-abdominal drains following kidney transplantation. <br/><br/>Aim: We conducted a systematic review and meta-analysis to determine whether such an approach brings any advantages in the prevention of perirenal transplant fluid collection, surgical site infection, lymphocele, hematoma, urinoma, wound dehiscence, graft loss, and need for reoperation. <br/><br/>Methods: We conducted a random-effects meta-analysis of non-randomized studies of intervention comparing drained and drain-free adult renal graft recipients regarding perirenal transplant fluid collection and other wound complications. ROBINS-I tool and funnel plot asymmetry analysis were used to assess the risk of bias. <br/><br/>Results: Five studies at moderate to critical risk of bias were included. A total of 2094 renal graft recipients were evaluated. Our analysis revealed no significant differences between drained and drain-free patients regarding perirenal transplant fluid collection (pooled odds ratio [OR], 0.77; 95% confidence interval [CI], 0.28-2.17; I 2 = 72%), surgical site infection (OR, 1.64; 95% CI, 0.11-24.88; I 2 = 80%), lymphocele (OR, 0.61; 95% CI, 0.02-15.27; I 2 = 0%), hematoma (OR, 0.71; 95% CI, 0.12-3.99; I 2 = 71%), and wound dehiscence (OR, 0.75; 95% CI, 0.21-2.70; I 2 = 0%). There was insufficient data concerning urinoma, graft loss, and need for reoperation. <br/><br/>Conclusions: The available evidence is weak. Our findings show that the use of intra-abdominal drains after kidney transplantation seems to have neither beneficial nor harmful effects on perirenal transplant fluid collection and other wound complications. The present study does not support the routine placement of surgical drains after kidney transplantation. <i>In this systematic review and meta-analysis we summarize the most up-to-date evidence for and against the routine use of intra-abdominal drain following renal transplantation.</i>.

We review the safety and early oncological outcomes of irreversible electroporation (IRE), a novel non-thermal ablation technique, in small renal masses (SRMs). Following PROSPERO registration (CRD42020197943), a systematic search of MEDLINE, EMBASE and SCOPUS databases according to PRISMA guidelines was performed. Critical appraisal of the included studies was performed using the Newcastle-Ottawa Scale. Of 224 articles screened, 10 met the inclusion criteria. In total, 83 patients were identified. Except for one cohort study ( = 41), the remaining studies were case series of < 10. Follow up was <12 months in 7/10 articles (range 3-34 months). About 10/10 articles reported safety outcomes. There were no 30-day mortalities. The most frequently reported adverse events were transient haematuria (11/83) and asymptomatic perirenal haematomas (7/83). About 62/63 patients with reported length of stay were discharged within 24 h. No significant long-term changes in renal function were reported. About 7/10 articles reported oncological outcomes. Only one article assessed histopathological outcomes, whilst the remaining studies used cross-sectional imaging modalities to assess efficacy, recurrence or disease progression. About 4/7 patients with histopathology outcomes, showed complete response (CR). About 43/55 patients with radiological outcomes showed CR. No mortalities were reported due to SRMs. These initial findings support IRE as safe and feasible in managing SRMs. However, results from larger studies with longer follow-up are needed to evaluate oncological outcomes and compare these with other ablation methods.
