The selected treatment approach should account for attendant risks and benefits of the intervention within the context of patient preferences and outcome expectations. Dr. Vasconcelos and colleagues from Brazil (5) present in page 969 a nice study about the association between attention-deficit/hyperactivity and lower urinary tract symptoms in children and adolescents in a community setting and concluded that Children and adolescents, recruited in a general pediatric outpatient clinic, with symptoms of attention-deficit/hyperactivity disorder (ADHD) symptoms are 2.3 times more likely to have LUTS. The combined type of ADHD was the most commonly associated with LUTS. Urgency and holding maneuvers were most prevalent symptoms in children and adolescents with ADHD symptoms. These findings support that all children with ADHD should be addressed for LUTS and vice versa. In page 979 Prof. Andrew Coombs (6) in a very nice editorial comment show some aspects of this important topic. Dr. Falahatkar and colleagues from Iran (7) present in page 982 a randomized double-blind clinical trial about Efficacy of tamsulosin versus tadalafil as medical expulsive therapy on stone expulsion in patients with distal ureteral stones and concluded that Tamsulosin as medical expulsive therapy is more effective for distal ureteric stones with less need for analgesics and less stone expulsion time than tadalafil. Dr. Frumer and colleagues from Israel (8) present in page 997 an interesting study about Sars--Cov 2 and Urological Emergencies and concluded that the general lockdown was accompanied by a significant decrease in common urological presentations to the emergency room. This change occurred across the clinical severity spectrum of renal colic, hematuria, and urinary retention. In the short term, it appears that patients who sought treatment did not suffer from complications that could be attributed to late arrival or delay in treatment. The long-term implications of abstinence from seeking emergent care are not known and require further investigation. Dr. Anaissie and colleagues from, USA (9) present in page 1006 an important study about the role of radical cystectomy (RC) and urinary diversion (UD) in post-operative complications and concluded that RC+UD, as compared to UD alone, is associated with an increased risk of major complications, including bleeding needing transfusion and venous thromboembolism. Additionally, continent UD had a higher risk of post-operative complication than ileal conduit. Dr. Oliveira and colleagues from Brazil (10) present in page 1020 an interesting translational study about the prostatic alterations associated to early weaning and its relation with cocoa powder supplementation in adult wistar rats and concluded that early weaning resulted in hyperglycemia and important morphological changes in the prostate. In contrast, dietary supplementation with cocoa powder attenuated these effects on the metabolism and prostatic histoarchitecture, proving to be a good nutritional treatment strategy. Dr. Favorito and colleagues from Brazil (11) present in page 1032 an important study about a new option to prevent fistulas in anterior urethroplasty in patients with kippered urethra: the tunica vaginalis flap (TVP) and concluded that a urethroplasty with TVF technique may be a viable method for repairing penile urethral erosions, but further studies are required with a bigger sample to confirm the results. We hope that readers will enjoy the present number of the International Brazilian Journal of Urology in this very difficult times of COVID-19.
