Pyogenic Granuloma is a benign vascular tumor that rarely reported in the urinary tract of pediatric population. Herein we present a case of a child followed for recurrent painless macroscopic hematuria. We performed ureteroscopy, and a whitish lesion was discovered in the upper calyx of the right kidney. The lesion resected endoscopically, and microscopic examination of the lesion was consistent with Pyogenic Granuloma. It is important for pediatricians and urologists to properly recognize Pyogenic Granuloma as a possible source of hematuria in the pediatric population...

REVIEW
Chad M Gridley, Bodo E Knudsen
The field of ureteroscopy has undergone a continual evolution since the first ureteroscopes were introduced. Over the past 10 years, we have entered into the digital era of ureteroscopy with both semirigid and flexible options becoming available. The following review looks at the benefits and drawbacks of digital flexible ureteroscopes as well as the current commercially available options.

Retrograde ureteroscopy (URS) has become a common procedure for the management of urinary stones. Although its efficacy and safety are well known, the literature about major complications is still poor. This study highlighted some cases of life-threatening complications after semirigid ureteroscopy (s-URS) or flexible ureteroscopy (f-URS). We enrolled experienced endourologists (more than 75 cases/year in the last 3 years) and we performed a survey asking to review their series and report the cases encumbered by major complications (Clavien-Dindo IIIb-IV grade)...

INTRODUCTION: Percutaneous nephrolithotomy (PNL) is usually performed worldwide with a rigid-only antegrade approach. Daily practice suggests that adding flexible nephroscopy and/or ureteroscopy to conventional rigid PNL might improve its efficacy and safety, but available evidence is weak. Appraisal of reliable outcomes of such PNL techniques would better guide intraoperative choices and optimize surgical results. Therefore our objective was to systematically review relevant literature comparing the outcomes of rigid-only PNL and combined flexible PNLs (adding flexible nephroscopy and/or flexible ureteroscopy) for the treatment of large and/or complex upper urinary tract calculi, with regard to efficacy and safety...

OBJECTIVE: To assess the feasibility and safety of a novel flexible mini-nephroscope in minimally-invasive PCNL. Presumably, limiting the size and number of tracts during percutaneous-nephrolithotomy(PCNL) has the potential of decreasing the morbidity of the procedure. We present our experience with, this new technique. METHODS: A retrospective analysis of patients with multiple kidney stones treated with mini-PCNL combined with a novel flexible mini-nephroscope was performed...

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...

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...
