Dr. Gan and Collegues (5) from China performed on page 786 an interesting study about thea novel semirigid ureterorenoscope with irrigation and vacuum suction system and a modified ureteral access sheath (UAS) to overcome the deficiencies of the current procedure and to improve the efficiency and safety during treatment of upper urinary calculi. This study is on the cover in this number and concluded that this new ureterorenoscope is technically feasible, efficacious and safe for treatment of upper urinary calculi because of its advantages of high stone free rate and low complication rates. Dr. Campos and Collegues (6) from Brazil and USA developed and validated on page 796 a new test of specific technical skills required for microsurgical varicocelectomy and suggested that the task--specific checklist of microsurgical varicocelectomy is reliable and valid in assessing microsurgical skills. Dr. Amaral and Collegues (7) from Brazil analyzed on page 805 the serum and urinary markers of the Renin-Angiotensin-Aldosterone System (RAAS) in myelomeningocele patients with renal function abnormalities detected on DMSA and shows that the analysis of serum Angiotensin-Converting Enzyme (ACE), Angiotensin-Converting Enzyme 2 (ACE 2) and urinary ACE were not significant in patients with myelomeningocele and neurogenic bladder with renal injury previously detected by renal DMSA. The Editor-in-chief expects everyone to enjoy reading and for sure better times will come soon.
