INTRODUCTION: Ureteroscopy has been shown to be a highly efficacious and safe modality for the treatment of pediatric urolithiasis. However, conventional ureteroscopy relies on fluoroscopy for intraoperative guidance, exposing both patient and operating room personnel to ionizing radiation. Pediatric urolithiasis patients are at a particularly increased risk from this radiation exposure. The use of ultrasound in place of fluoroscopy for intraoperative guidance has emerged as one modification that can reduce radiation exposure during ureteroscopy...

OBJECTIVES: In the pediatric population, there have been significant improvements in the treatment of stones in recent years. Conventionally, ureteroscopy (URS) and/or retrograde intrarenal surgery (RIRS) are techniques performed with fluoroscopy. When using fluoroscopy, problems, including malignancy, may arise due to radiation exposure in the patient, physician and operation room staff. The aim of this study is to evaluate the possibility of ureteroscopic treatment without fluoroscopy in children with ureteral and renal stones...

PURPOSE: To investigate the morbidity, complication rate, and pain perception during removal of a novel ureteric stent with a magnetic end using a-traumatic retrieval catheter. METHODS: Between November 2013 and July 2015, 151 consecutive patients who underwent semirigid ureterorenoscopy (URS) for stone removal were prospectively enrolled. Stent removal was performed under local anesthesia using a special magnetic-end stent remover 1 week following URS. At follow-up, we obtained patients' medical history, urine culture result, renal ultrasonogram, and visual analog scale (VAS) score regarding stent irritation (VAS 1) and pain during removal (VAS 2)...

Congenital anomalies of the kidneys and urinary tracts can result in diminished natal kidney function, possibly through common embryologic pathway disruption or as a result of development taking place in the face of disordered 'post-renal' drainage. Impaired conduit and reservoir function present potential for an ongoing assault leading to further deterioration and progression of chronic kidney disease, a risk that extends to adults with these conditions, even after "correction". The drainage and storage aspects of the urinary system that can impact kidney function are reviewed with attention to correctable or manageable problems including: Bladder dysfunction wherein the low pressure storage of urine is compromised requiring the kidney to work against a pressure gradient, the classic post renal failure problem...

Maintenance of flexible ureteroscopes can involve high costs and administrative burden. Instrument fragility necessitates eventual repair, rendering scopes inaccessible during refurbishment. We conducted a multi-institutional prospective cohort study to identify perioperative factors influencing flexible ureteroscope durability. Patients undergoing flexible ureteroscopy (URS) at six United States endourology centers were enrolled between August 2014 and June 2015. Surgeon self-reported concern and satisfaction with scope performance as well as upward and downward angles of deflection for each scope tip were measured before and after each procedure...

We have developed the Peralta Stone Extraction System to increase the safety of ureteral stone extraction. The device combines a nitinol stone basket and low-pressure balloon into a single device. After visualization, the stone is captured in the tipless nitinol basket and enveloped by a low-pressure balloon. We tested the performance of device prototypes in a porcine model using stone mimics with diameters ranging from 4.2 to 6.2mm. Stones extracted with the device required less force when compared with stones in a standard ureteral stone basket...

Purpose With advances in technology, ureteroscopy is increasingly utilized for the management of urolithiasis. Previous studies have attempted to characterize the post-operative complication and readmission rates relative to the technical difficulty of the procedure. There is limited data exploring resident level of training and its effect on adverse outcomes in these cases. We review our experience with ureteroscopy to create a model to predict factors, including resident experience,that affect rates of post-operative complications Materials and Methods We reviewed ureteroscopies performed at our academic facility from January 2009 to December 2013...

INTRODUCTION: Surgical treatment of pediatric kidney stones has changed dramatically in recent years because of the miniaturization of surgical instruments and the availability of intracorporeal lithotripters. The retrograde intrarenal surgery (RIRS) technique is nowadays considered an effective and safe procedure but studies in very young children are lacking and use of a ureteral access sheath (UAS) has also been debated. OBJECTIVE: To assess safety and efficacy of RIRS using UAS in children weighing < 20 kg...

Bladder exstrophy is a malformation characterized by subumbilical anterior abdominal wall and anterior bladder wall deishence. It affects nearly 30.000-40.000 births per year, with a higher prevalence in boys. External continent urinary diversion creates a long-term outcome. However, it is not devoid of complications. We report the case of a 30-year old female patient who had undergone cystectomy with bladder replaced with ileo-caecal segment for bladder exstrophy 13 years earlier. She was followed up for 5 years and then lost to follow up...
