BACKGROUND: Percutaneous nephrolithotomy (PCNL) is recommended for treating staghorn stones or stones measuring > 20 mm. Extracorporeal shockwave lithotripsy (ESWL) or flexible ureteroscopy (URS) may be used as a complement. However, PCNL can cause trauma to the kidney parenchyma, and patients may find a noninvasive procedure, such as ESWL, to be more attractive. OBJECTIVES: The aim of this study was to evaluate the clinical efficiency of MiniJFil® stenting associated with ESWL or second-line URS for the treatment of medium-to-large kidney stones...

Background: Flexible ureteroscopy (fURS) is one of the main treatment options for urolithiasis less than 2 cm. Although fURS has no relative contraindication, some anatomical factors may need to be considered, as not all patients are suitable for the regular lithotomy position (LP). We report the case of a patient with a right iliac vascular graft that after an fURS without intraoperative incidences developed a reperfusion syndrome of the right lower limb. Case Presentation: A 46-year-old male patient was referred for treatment and follow-up in the cystinuric clinic after being found to have a 3 cm pelvic stone with a Double-J catheter in place after two failed sessions of shockwave lithotripsy...

: Purpose We sought to test the content validity of a new training model for flexible ureteroscopy: the Key-Box. Material & Methods Sixteen medical students were randomized to either a training group (n=8) that underwent 10 days of training on 10 different exercises to learn (1) specific movements for the flexible ureteroscope and (2) how to catch and release stones with a nitinol basket using the Key-Box, or a non-training control group (n=8). Subsequently, an expert endourologist (OT) blindly assessed the skills of all students (trained and non-trained) by observing their performance on two ureteroscope manipulation exercises and one stone capture exercise...

REVIEW
Ahmed M Harraz, Ahmed I Kamal, Ahmed A Shokeir
Urolithiasis in the context of renal transplant is a quite rare event that requires keeping a higher index of suspicion and vigilance. Donors with incidentally discovered asymptomatic renal stones "donor gifted lithiasis" are potentially considered for donation should they are not recurrent stone formers and in the absence of active biochemical disorders. Stone clearance from the donors can be done before donation using shock wave lithotripsy and/or flexible ureteroscopy. Ex vivo ureteroscopy at time of transplant is equally feasible and safe...

BACKGROUND: Controversy remains on the superiority of combination therapy over monotherapy on ureteral stent-related symptoms (SRSs). We tend to explore if there is a necessity of combination therapy. METHODS: One hundred cases of unilateral upper urinary tract calculi with stent insertion (pre and post flexible ureteroscopy) were randomized into 4 groups, given non-treatment, solifenacin, tamsulosin or combination respectively. Eight times of follow-ups were given after each insertion...

Open ureterolithotomy and pyelolithotomy used to be first line therapy for treating kidney and ureteral stones. With the advent of shockwave lithotripsy, open stone surgery became less prevalent, but once ureteroscopy became more prevalent, open stone surgery became all but extinct. Advances in smaller, more flexible endoscopes and improvements in intracorporeal lithotripters, ureteroscopy has become a mainstay of therapy for kidney stones. The holmium:YAG laser can be utilized through flexible instruments and fragments any stone no matter what it is composed of...
