This study was proposed to compare the clinical effectiveness of mini-tract percutaneous nephrolithotomy (MPCNL) with standard-tract percutaneous nephrolithotomy (SPCNL) and verify whether MPCNL is associated with both higher renal pelvic pressure (RPP) and incidence of postoperative fever. A total of 228 patients with kidney stone were randomly allocated to the MPCNL group (n=114) and SPCNL group (n=114). Both intraoperative and postoperative indexes along with the incidence of complications were compared between the two treatment groups...

About 10% of the people is the subject of an episode of kidney stones during their lifetime, about 70% of these people undergoes relapses. About 80% of the urinary stones contains calcium, of wich 80% is formed of calcium oxalate, in pure form or associated with calcium phosphate. Therefore we can saythat in most cases (about 65%) the urinary stones are composedof calcium oxalate. Use of supplements of potassium citrate and magnesium citrate can help in the prevention of kidney stones of calcium oxalate, but mostly they can be used in the days before a shockwaves lithotripsy treatment to make the stones more fragile to the effect of the shock waves...

OBJECTIVE: Urolithiasis of the transplanted kidney has an incidence of 0.2 to 1.7%, it increases the risk of infection in immunosuppressed patients and it can lead to ureteral obstruction that is often associated with deterioration of renal function. Urolithiasis of the transplanted kidney has different characteristics compared to the native kidney, due to the absence of innervation, which does not lead to colic pain. Percutaneous approach is an optimal choice in transplant patients. MATERIAL AND METHODS: Here we report our experience in two cadaveric transplant patients with urolithiasis...

We present the case of a 37-year-old lady who presented with severe colicky left sided flank pain associated with vomiting, chills and rigors. A non-contrast Computed Tomography of the Kidney Ureter and Bladder was performed which showed a 2-3 mm stone in the pelvic part of the left ureter. Following 2 days of conservative treatment she was still complaining of increasingly severe pain. A contrast computed tomography of the abdomen was performed which was suggestive of a perforation of the left collecting system...

CONTEXT AND AIMS: Ureteroscopy is the definitive management for ureteric stone. Conventional ureteroscopy uses fluoroscopy guidance which has radiation exposure to patients as well as hospital staff. Ultrasound is a good radiation-free alternative for using in the urological procedure. With this background, we executed a prospective randomized trial comparing fluoroscopy-guided ureteroscopy versus ultrasound-guided ureteroscopy. SUBJECTS AND METHODS: Patients were randomized into two groups (41 into fluoroscopy and 41 into ultrasound group after exclusion) in a single center from July 2014 to March 2015...

BACKGROUND: Stone retropulsion represents a challenge for intracorporeal lithotripsy of ureteral calculi. The consequences are an increased duration and cost of surgery as well as decreased stone-free rates. The use of additional tools to prevent proximal stone migration entails further costs and risks for ureteral injuries. We present the simple technique of using a coil of the routinely used guidewire to prevent stone retropulsion. METHODS: We retrospectively evaluated all patients with mid-to-proximal ureteral stones in 2014, which were treated by ureteroscopic lithotripsy (Ho: YAG and/or pneumatic lithotripsy)...

OBJECTIVES: Although previous studies have indicated that stone heterogeneity can affect shock wave lithotripsy outcomes, there is no established measurement of stone heterogeneity on computed tomography imagery. We investigated whether variation coefficient of stone density can predict shock wave success. MATERIALS AND METHODS: We conducted a retrospective review of 245 patients with urinary calculi who had undergone shock wave lithotripsy. We compared the predictive powers of treatment success between variation coefficient of stone density and other parameters associated with computed tomography attenuation...

INTRODUCTION: Ureteroscopy is increasingly used to treat upper tract urinary stone disease. A negative ureteroscopy is a ureteroscopy performed with the intent of removing a kidney or ureteral stone, but in which ultimately no stone is removed. Negative ureteroscopy may occur when the stone is found to have already passed, or the presumed stone is found to be outside of the collecting system. We sought to determine the rate of negative ureteroscopy in a large population-based sample as well as factors associated with its use...

We performed extracorporeally induced destruction of kidney stones on 72 patients. No complications have resulted from the tissue exposure to high energy shock waves. Clearance studies before and after the shock wave treatment indicate no changes in renal function. The method was used successfully in all patients with stones in the renal pelvis. In none of these patients was an open operation required. Two patients with ureteral stones also were treated with shock waves but had to be operated upon because of insufficient destruction of the stone...

BACKGROUND: In recent years, the incidence of urinary stone disease reportedly has been increasing. The use of shockwave lithotripsy has seen low success rates, the inefficacy of a single session, and the need for general anaesthesia in children; additionally, children are exposed to radiation. These suboptimal treatment conditions have all led to ureteroscopy (URS) becoming the treatment method of choice for paediatric ureter stones. The aim of this study is to examine the effectiveness of 4...

OBJECTIFS: Double J ureteral stents (DJ), whatever their material, are rapidly covered by a biofilm, subject to encrustation onset. To prevent this, it is admitted that DJ should be replaced periodically. However, encrustation may vary with indication, with a highest risk in "stone" patients. Our target was to evaluate the actual DJ medium/long-term indwelling times and relevant encrustation rates perceived by urologists in daily practice. MéTHODES: Data were collected through an observational retrospective study...
