introduction: to compare outcomes of retrograde intrarenal surgery (rirs) with extracorporeal shock wave lithotripsy (eswl) as treatment of choice. methods: a total number of 46 patients with renal pelvic stones 10-20 mm and body mass index (bmi) >30 randomized in two groups underwent rirs and eswl from 2011 to 2014 and followed for 3 months. results: the patients mean ± sd age was 36.1 ± 13.1 ...

background urinary stone incidence in pregnancy has been reported in a wide range, from 1 in 200 to 1 in 2000 cases. objectives the aim of this study was to investigate the efficacy and safety of ureteroscopic treatment and its results and complications for pregnant women with urinary stones. patients and methods from 2003 till 2011, 113 pregnant patients with symptomatic urolithiasis were admi...

This study aimed to evaluate the clinical value of a novel ureter dilatation method during ureteroscopic pneumatic lithotripsy in patients with ureteral calculi and polyps. Clinical information of 86 patients with ureter calculi and polyps who underwent ureteroscopic pneumatic lithotripsy was reviewed. A cavity-distention machine was used in 44 cases to inject normal saline for keeping clear op...

PURPOSE To evaluate the effects of a reverse thermosensitive polymer during ureteroscopy with laser lithotripsy in an in vivo porcine model. MATERIALS AND METHODS Six pigs underwent general anesthesia followed by bilateral ureteroscopy with laser lithotripsy of stone phantoms while measuring intrapelvic renal pressures through bilateral nephrostomy tubes. The procedures were performed in one ...

INTRODUCTION Extracorporeal shockwave lithotripsy (ESWL) is the treatment modality of choice of many urologists for proximal ureteric calculi. In this study, we compared the efficacy and safety of ESWL versus ureteroscopy with holmium laser lithotripsy for the treatment of this group of stones. MATERIALS AND METHODS Between May 1999 and October 2000, 50 patients had ESWL and another 51 patien...

biological effects extracorporeal shock wave lithotripsy (eswl) is not precisely known. we have evaluated two urinary enzymes activity n-acetyl-b-d-glucosamine (nag) and alanine amino peptidase (aap) before and after unilateral eswl as markers for renal parenchymal damage. forty eight patients with kidney stones (mean age 39) who had presented for the first time or at least one year after their...

BACKGROUND Pyelocaliceal calculi flexible ureteroscopic approach raises problems related to operative time, associated morbidity and costs, especially by potential endoscope damage. METHODS 5 series, each of 20 patients with single pyelocaliceal lithiasis, were analyzed: Group I with calculi 1 cm fragmented to dust, Group II with calculi 1 cm with lithotripsy in fragments, Group III with calc...

PURPOSE We determined whether shock wave lithotripsy of the kidney of pigs with metabolic syndrome would worsen glucose tolerance or increase the risk of diabetes mellitus. MATERIALS AND METHODS Nine-month-old female Ossabaw miniature pigs were fed a hypercaloric atherogenic diet to induce metabolic syndrome. At age 15 months the pigs were treated with 2,000 or 4,000 shock waves (24 kV at 120...

BACKGROUND Hepatolithiasis is very common in East Asia. It is benign in nature, but has a high recurrence rate. It is likely to lead to biliary cirrhosis and increase the risk of cholangiocarcinoma. Hence, the treatment of hepatolithiasis is difficult but vital. In this report, we present a novel approach to manage hepatolithiasis using the choledochoscopic Frequency-Doubled Double pulse Nd:YAG...

UNLABELLED The safety and efficacy of endoscopic sphincterotomy with large balloon dilation (EPLBD) are unclear. This study compares the safety and efficacy between EPLBD and endoscopic sphincterotomy (EST). PATIENTS AND METHODS Literatures were searched for randomized controlled trials in PUBMED, EMBASE, and Cochrane Library. Outcome measurements included adverse events; stone removal rate; ...
