background retrograde intra-renal surgery (rirs) has been used to remove stones of less than 2 cm in the kidney. however, its role is not well defined. objectives the objective of this study was to evaluate the outcomes and safety of rirs, used either as a primary or secondary procedure, and to analyze factors predicting the stonefree rate (sfr). patients and methods a retrospective analysis wa...

The treatment of renal stone disease is very dependent on the composition of the stone. Uric acid stones for example have a completely differerent eitiology and treatment pathway to calcium phosphate or oxalate stones. Until now, the diagnosis of renal stone disease was mainly done through urine analysis and formal stone analysis once the stone has been removed. There is now a novel method of a...

A 79-year-old male with chronic myelomonocytic leukaemia and extensive bilateral renal stone disease was treated with intravenous rasburicase for persistent hyperuricaemia. Subsequent imaging revealed a complete dissolution of stone burden, avoiding the need for complex, invasive stone surgery and further renal replacement therapy.

The purpose of this study was to define factors that have a significant impact on the stone-free rate after ESWL. Methods: A total of 417 patients harboring renal or ureteral stones underwent extracorporeal shock wave lithotripsy (ESWL) between October 2008 and July 2012. Eighty five patients were lost on follow up. The remaining (n = 332). All patients were >18 yr of age. Siemens and SLX-F2 el...

Giant renal calculus is rarely seen in urologic practice. A 69-year-old woman who had right giant renal calculus with poorly functioning opposite kidney is presented. She was with a history of right pyelolithotomy for large renal calculus 10 years back. Ultrasonography(USG), uncontrast computed tomography ( CT ), plain abdominal X-ray ( KUB ) and intraveneous urography ( IVU ) revealed a giant ...

Purpose To evaluate the impact of various computed tomography scan-based parameters of renal stones on the outcome of extracorporeal shock wave lithotripsy (ESWL). Materials and Methods We conducted a retrospective study of patients who underwent ESWL for renal stones (sized 5-20 mm) from January 2013 to December 2016. We evaluated body mass index, location of the stone, skin-to-stone distanc...

Background: The aim of this study was to describe the one-decade experience in Percutaneous Nephrolithotomy surgery in children with kidney stones in Tehran, Iran. Methods: All patients (less than 18 years old) undergoing Percutaneous Nephrolithotomy at our referral medical center, were reviewed in this cross-sectional study. All the demographics, surgical data and post-operative information...

Kidney stone disease is a crystal concretion formed usually within the kidneys. It is an increasing urological disorder of human health, affecting about 12% of the world population. It has been associated with an increased risk of end-stage renal failure. The etiology of kidney stone is multifactorial. The most common type of kidney stone is calcium oxalate formed at Randall's plaque on the ren...
