Management of 1-2 cm renal stones
Introduction: The preferred treatment of <1cm stone is shockwave lithotripsy (SWL), while that of stone >2 cm is percutaneous nephrolithotomy (PCNL), but treatment of 1-2 cm renal stones is a controversial issue. We searched the literature to present a comprehensive review on this group.
Material and Methods: Pubmed search of literature was done using the appropriate key words. We separately discussed the literature in lower polar and non lower polar stone groups.
Results: For non lower polar renal stones of 1-2 cm, SWL is preferred approach, while for the lower polar stones; literature favors the use of PCNL. Retrograde intrarenal surgery (RIRS) is emerging as a promising technique for these calculi.
Conclusions: Treatment of renal stone disease depends on stone and patient related, as well as on renal anatomical factors. Treatment should be individualized according to site of stone and available expertise
What is the role of adjuvant chemotherapy in locally advanced and lymph node-positive bladder cancer after radical cystectomy?
Does treatment rate impact the efficacy of extracorporeal shock wave lithotripsy for kidney or ureteral stones?
What happens to the patients with muscle-invasive bladder cancer who refuse cystectomy after neoadjuvant chemotherapy?
Hemodialysis vascular access options after failed Brescia-Cimino arteriovenous fistula
The survival of patients on long-term hemodialysis has improved. End-stage renal disease patients now need maintenance of their vascular access for much longer periods. Arteriovenous fistulae formed at the wrist are the first choice for this purpose, but, in many patients, these fistulae fail over time or are not feasible because of thrombosed veins. We searched the Pubmed database to evaluate the various options of vascular access in this group of patients based on the published literature. It is quite evident that, whenever possible, autogenous fistulae should be preferred over prosthetic grafts. Use of upper arm cephalic and basilic veins with transpositions wherever required can enhance autogenous fistula options to a large extent. Upper arm grafts should be used when no autogenous fistula is possible. Lower limb and body wall fistula sites are to be considered at the end, when all options in both upper limbs are exhausted
