To compare the outcome of mini-percutaneous nephrolithotomy (Mini-PNL) versus standard-PNL for renal stones. Retrospective study was performed between March 2010 and May 2013 for patients treated by Mini-PNL or standard-PNL through 18 and 30 Fr tracts, respectively, using pneumatic lithotripsy. Semirigid ureteroscope (8.5/11.5 Fr) was used for Mini-PNL and 24 Fr nephroscope for standard-PNL. Both groups were compared in stone free rate(SFR), complications and operative time using Student-t, Mann-Whitney, Chi square or Fisher's exact tests as appropriate in addition to logistic regression analysis...

A renal artery pseudoaneurysm is a rare but important complication that can occur after renal trauma, renal biopsy, percutaneous nephrostomy, percutaneous nephrolithotomy (PCNL), and partial nephrectomy. The incidence of this potentially life-threatening complication is less than 1%, but is likely to increase with the increasing popularity of endoscopic renal procedures. We present a case of a 30-year female who underwent right PCNL for a right renal pelvic stone. Two weeks later, she presented with massive hematuria...

In this study, we aimed to determine factors affecting the success rate of percutaneous nephrolithotomy (PNL) in children. The series consisted of 41 consecutive children operated on by the same surgical team for renal calculi with PNL between June 2002 and May 2015 in our institution. A single calyx or pelvic stone was described as simple, while calculi located in more than one location (calyx and pelvis or more than one calices) or staghorn stones were described as complex. The procedure was deemed successful if the patient was completely stone-free (SF) or had residual fragments <4 mm...

Background: Percutaneous nephrolithotomy (PNL) is a procedure that has traditionally been performed in an inpatient or hospital setting. Many surgical procedures have evolved over time from an inpatient/hospital setting to outpatient procedures performed in surgical centers. Outpatient PNL has become an accepted standard in select patients, but to date, the procedure has not been performed in an outpatient surgical center. Case Presentation: We describe our initial experience managing large renal stone burden with PNL performed completely outpatient in a freestanding ambulatory surgery center...

The concept of adipose tissue as an organ unto itself represents a new medical construct; already differences in the volume of perirenal fat around a tumor-bearing kidney have been described. We hypothesized that renal calculi may have similar impact on perirenal fat or alternatively abnormalities in urinary metabolites may be the result of perirenal fat affecting renal metabolism and subsequent stone formation. Accordingly, we conducted a study utilizing three-dimensional imaging software to evaluate perirenal fat volume (PFV) in patients with nephrolithiasis...

The improvement of surgical care requires transparent, consistent and accurate reports concerning surgical outcomes which are assessed and documented in a standardized manner. No consensus has yet been reached as to how to define and assess postoperative complications with regard to the specificity of urological procedures. Therefore, the comparison of data from different centres is difficult. The modified Clavien-Dindo classification allows for a more uniform analysis of surgical complications. This study analyses the occurrence of perioperative complications after percutaneous nephrolithotomy assessed on the basis of the aforementioned classification...
