BACKGROUND Although the application of ureteroscopy in the treatment of ureteral calculi during pregnancy has been on the rise, for persistent renal colic patients without ultrasound-detected ureteral calculi, it may represent a clinical dilemma due to the potential risks for both mother and fetus. OBJECTIVE The aim of the present study is to present our experience with the application of the...

Introduction. Open surgical anatrophic nephrolithotomy (ANL) had been the standard treatment for large renal calculi prior to the development of endoscopic devices and endoscopic techniques. A previous report described the efficacy of ureteroscopy-assisted retrograde nephrostomy (UARN) and presented a case of renal calculi successfully treated with UARN during percutaneous nephrolithotomy (PCNL...

Background: Urinary calculi have serious implications in urology. Lower ureteral stones can cause obstructive uropathy and subsequent deterioration of renal function. Because the patient’s symptoms stone size do not predict loss function because there is no clear time threshold for irreversible damage, treatment should be strongly considered any patient with stones. In this study we are compari...

Drug-induced renal calculi represent 1-2% of all renal calculi. In the last decade, drugs used for the treatment of HIV-infected patients have become the most frequent cause of drug-containing urinary calculi. Among these agents, protease inhibitors (PIs) are well known to induce kidney stones, especially indinavir and atazanavir, and more recently darunavir. Urolithiasis attributable to other ...

INTRODUCTION In the current age of minimally invasive therapy, it is reasonable to offer open nephrolithotomy as the first line treatment for patients with complete staghorn renal calculi and/or infandibular stenosis. (1) The role of laparoscopic surgery as...
