OBJECTIVES To evaluate semirigid retrograde ureteroscopy complications on a significant series of patients and to establish the factors associated with the occurrence of intraoperative complications. PATIENTS AND METHODS Between June 1994 and June 2013, 8150 semirigid ureteroscopic procedures for ureteral lithiasis were performed in 7456 patients. We used semirigid ureteroscopes(8 9.8F Wolf, ...

Urolithiasis is the formation of stones in the urinary tract, causing pain and bleeding, and may lead to secondary infection. It is the third most common affliction of the urinary tract. Of many types of stones that are formed, the most common are calcium oxalate. The formation of such concretion encompasses several physicochemical events beginning with crystal nucleation, growth, aggregation, ...

OBJECTIVE Urinary lithiasis affects between five and 10% of the human population during their lifetime, only 2-3% of whom are children. Therapy of urolithiasis in the pediatric age group with minimally invasive methodology represents an attractive alternative. This study presents results of extracorporeal shockwave lithotripsy, a minimally invasive methodology, for the treatment of urinary lith...

INTRODUCTION In special situations such as malrotated or ectopic kidneys and UPJ stenosis treatment of renal lithiasis can be challenging. In these rare cases laparoscopy can be indicated. OBJECTIVE Describe the Laparoscopic-assisted rigid nephroscopy performed via transpyelic approach and report the feasibility. PATIENTS AND METHODS We present two cases of caliceal lithiasis. The first is ...

BACKGROUND endoscopic ultrasonography (EUS) and magnetic resonance cholangiography (MRC) are the elective tests in the diagnosis of choledocholithiasis. MRC is best accepted by patients, but its sensitivity might decrease in the evaluation of microlithiasis. AIM to evaluate the diagnostic accuracy and therapeutic impact of EUS in a prospective cohort of patients with intermediate suspicion of...

INTRODUCTION Laparoscopic surgery through a single port is an evolution of laparoscopic surgery, possible after recent technological development of new access systems. It is an established minimally invasive technique, although its indications in the field of Urology are currently under development. MATERIAL AND METHODS We present the first case of incision-less pyelolithectomy, performed thr...

Cystinuria is a hereditary disorder caused by a defect in the apical membrane transport system for cystine and dibasic amino acids in renal proximal tubules and intestine, resulting in recurrent urolithiasis. Mutations in SLC3A1 and SLC7A9 genes, that codify for rBAT/b(0,+)AT transporter subunits, cause type A and B cystinuria, respectively. In humans, cystinuria treatment is based on the preve...

INTRODUCTION Laparoscopic surgery is following a natural course as it decreases surgical aggression on the abdominal wall without undermining the curative and functional results. Although it is still being developed, single port surgery has meant an advance in this sense. MATERIAL AND METHODS We present the first single port laparoscopic pyelolithectomy surgery in horseshoe kidney, using conv...

There is still an ongoing debate regarding the optimal endourological treatment of upper urinary tract lithiasis, a significant parameter being the stone free rate. However, despite the apparent simplicity of notions such as stone free or success rate, when analyzing the available literature one may discover the complex, intricate and debatable issues behind them. The main problems reside in th...
