Evidence-practice gaps exist in urology. We previously surveyed European Association of Urology (EAU) guidelines for strong recommendations underpinned by high-certainty evidence that impact patient experience which practice variations were suspected. The recommendation "Do not offer neoadjuvant androgen deprivation therapy (ADT) before surgery patients with prostate cancer" was prioritised further investigation. ADT is neither clinically effective nor cost and has serious side effects....

Fetal urinomas are often diagnosed in prenatal ultrasonography. The etiology is usually an obstructive uropathy leading to hydronephrosis and increased intrarenal pressure putting future kidney function at risk. Rupture of pyelocaliceal system such cases may lead retroperitoneal urinoma or urinary ascites, sepsis, uraemia, acute renal failure. On the other hand, this serve as “pop-off valve” mechanism decreasing protecting from definitive loss. We present a case newborn girl with urinoma,...

Pediatric urolithiasis is a very specific and challenging problem in the field of modern urology. Currently, there are three major methods for kidney stone removal: extracorporeal shock wave lithotripsy (ESWL), retrograde intrarenal surgery (RIRS), percutaneous nephrolithotomy (PCNL), latter one proving to be an efficient safe monotherapy stones even with larger burden. Different sizes nephroscopes used (standard, mini, micro), where smaller size logically correlated safer profile,...
