| 1 | Multitract percutaneous nephrolithotomy in staghorn calculus显示文摘Staghorn calculi are branched stones which occupy a majority portion of the pelvicaliceal system.An untreated staghorn calculus over time can damage the kidney and deteriorate its function and/or cause life threatening sepsis.Total stone clearance is an important goal in order to eradicate any infective focus,relieve obstruction,prevent recurrence and preserve the kidney function.Percutaneous nephrolithotomy(PCNL)is currently the accepted first-line treatment option for staghorn calculi.The options available are single-tract PCNL with an auxiliary procedure like shockwave lithotripsy,single-tract PCNL with flexible nephroscopy,or multitract PCNL.Each has its own pros and cons.But the ultimate goal of treatment for any patient with staghorn calculi should be safety,cost-effectiveness,and to achieve total stone clearance.With this article,we review the management of staghorn calculi with multiple percutaneous(“multitract”)access,its advantages and disadvantages and its current position by studying the various published materials across the globe. | Arvind P.Ganpule MNaveen Kumar Reddy SBSudharsan Shaishav BShah Ravindra BSabnis Mahesh RDesai | 2020 | Asian Journal of Urology2020，7，2： | 4 |

| 4 | Synthesis and microwave dielectric behavior of (Bi_(1-x)Pb_(x))NbO_(4) ceramics显示文摘Ceramic samples of(Bi_(1-x)Pb_(x))NbO_(4)(x=0,0.025,0.05,0.10,0.15,0.20)with 0.75 wt.%V2O5 addition sintered at 920℃,940℃ and 960℃ are investigated.Pb is selected as a substitute for Bi^(3+)in BiNbO_(4) ceramics as it exists in two stable valence states of+2 and+4 and the average valency matches to that of Bi^(3+).The average Shannon radius(for octahedral coordination)of Pb^(2+)(1.19Å)and Pb^(4+)(0.775Å)cations is 0.9825Å,which is similar to that of Bi^(3+)ion(1.03Å).The dense(>94%)polycrystalline(Bi_(1-x)Pb_(x))NbO_(4) samples fabricated mostly reveal orthorhombic(Pnna)phase(α-BiNbO_(4),Sp.Gp.52)by powder XRD.Presence of satellite Pb2Nb2O7 phase,the amount of which is increasing with increase in Pb content,is also noticed.The microwave dielectric constant(ε'r)values of the niobates are found to increase from 42 to 71,whereas the quality factor(Qu.f)values are found to decrease from 5400 to 550 GHz with increasing substitution of Pb.The compositions so synthesized are important as hardly there are any microwave dielectric ceramics available with 45<ε'r<75. | S.P.Butee K.R.Kambale Shaishav Upadhyay S.Bashaiah K.C.James Raju Himanshu Panda | 2016 | Journal of Advanced Dielectrics2016，6，1： | 0 |
