We describe the use of the Uro Dyna-CT, an imaging system used in the operating room that produces real-time three-dimensional (3D) imaging and cross-sectional image reconstructions similar to an intraoperative computerized tomography, during a percutaneous nephrolithotomy and a contralateral flexible ureteroscopy in a complete supine position. A 65 year-old female patient had an incomplete cal...

PURPOSE It is believed that extracorporeal shock wave lithotripsy (ESWL) may be less effective than other modalities for treating stones in complex calculi. In this study, we investigated the efficacy of ESWL for treatment of complex stones. MATERIALS AND METHODS Between September 2002 and October 2003, 250 complex cases of urolithiasis, including ureteral stones, staghorn stones, and stones ...

INTRODUCTION Hemorrhage is a major complication after percutaneous nephrolithotomy (PCNL). In the current study, we analyzed the risk factors for severe bleeding after PCNL. MATERIAL AND METHODS Medical records of 982 consecutive patients undergoing PCNL at the Department of Urology, the Third Xiangya Hospital, were reviewed. The type of stone included: solitary (n = 471), multiple (n = 192) ...

BACKGROUND AND OBJECTIVES Cystinuria is a rare inherited renal stone disease. Mutations in the amino acid exchanger System b(0,+), the two subunits of which are encoded by SLC3A1 and SLC7A9, predominantly underlie this disease. The work analyzed the epidemiology of cystinuria and the influence of mutations in these two genes on disease severity in a United Kingdom cohort. DESIGN, SETTING, PAR...

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 AND OBJECTIVES Presently, percutaneous nephrolithotomy (PCNL) is a well-established and effective method of treating upper urinary tract stones at our institution. The aim of this paper was to evaluate a single surgeon's four-year experience of PCNL in the Singapore General Hospital. MATERIALS AND METHODS Between January 1996 and December 2000, 300 PCNLs were performed on 280 ren...

BACKGROUND Transcatheter renal artery embolization is an effective and minimally invasive treatment option for acute renal bleeding. Early post-interventional complications include groin hematoma, incomplete embolization, coil misplacement and coil migration. Late complications are rare and mostly related to coil migration. CASE PRESENTATION A 22-year-old woman with a history of recurrent sto...

Percutaneous Nephrolithotomy is currently the preferred first line treatment for simple & complex renal calculi. The technique also being used increasingly for smaller stones that have failed ESWL. Aim of the study is to share our experience in PCNL in course of time. This study was conducted from January 2009 to December 2012, 131 patient's with 142 renal units of 5-75 yrs of age, PCNL were pe...

Since August 1989, we have seen 4 patients with leukoplakia of the renal pelvis associated with a longstanding renal stone. In 2 of them, excretory or retrograde pyelography revealed multiple filling defects in the left renal pelvis as well as a renal stone, although urine cytological examination was negative. One of the other 2 patients underwent extracorporeal shock wave lithotripsy (ESWL) fo...
