Although stone free rates were quite high in both size categories (95% versus 89%, respectively), retreatment rates were significantly higher in the larger stone group (45% versus 11%, respectively), translating into an efficiency quotient of 81 for treatment of stones ≤ 7 mm and 58 for stones > 7mm. Although this size cutoff was chosen randomly, it provides a reasonable algorithm to guide trea...

OBJECTIVES To report our experience of diagnosis and multimodal management of urolithiasis in renal transplantation. PATIENTS AND METHODS From January 1995 to December 2012, 953 patients underwent renal transplantation in the Kidney Transplant Unit of Treviso General Hospital. Ten (10%) of them developed urinary calculi and were referred at our institution. Their mode of presentation, investi...

Objective: To compare the effects of calculus removal through nephroscopy and holmium laser calculus removal through ureteroscopy on patients with concurrent urinary infection at one side of their upper ureteral calculi. Method: A total of 160 patients admitted to our hospital because of concurrent urinary infection at one side of their upper ureteral calculi were selected from March 2014 to Fe...

INTRODUCTION AND OBJECTIVES We report the results of a randomized controlled trial comparing three different lithotriptors using semirigid ureteroscopy (URS) for distal ureteral stones. METHODS Between September 2009 and November 2010 69 patients undergoing ureteroscopy were randomized to three groups: LithoClast classic (Group 1), Holmium Laser (Group 2), and StoneBreaker™ (Group 3). A 7.5F ...

A twenty-eight-year-old female with a history of suprapubic pain and recurrent urinary tract infections presents for urology referral with a kidney, ureter, and bladder radiograph showing a 4.4 cm bladder calculus and 6.5 cm distal left ureteral stone. She underwent effective cystolitholapaxy of the bladder stone. Endourologic attempt (left ureteroscopy) was unsuccessful because of ureteral sto...

BACKGROUND AND PURPOSE Ureteroscopy is nowadays one of the techniques most widely used for upper urinary- tract pathology. Our goal is to describe its complications in a large series of patients. PATIENTS AND METHODS Between June 1994 and February 2005, 2436 patients aged 5 to 87 years underwent retrograde ureteroscopy (2735 procedures) under video and fluoroscopic assistance. We used semirig...
