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...

A 46-year gentleman presented with a left-sided lumbar region pain without fever or dysuria. He denied episodes of acute urinary retention. There was a hard mass at the distal urethra with normal laboratory blood tests. Computed tomography urogram revealed a concurrent left renal staghorn calculus and large distal urethral stone. The urethral stone was fragmented via endourologic technique successfully. We report a case of a non-obstructing large urethral calculus in a gentleman with concurrent left renal staghorn calculus and discuss the literature review...

A 40-year-old man was referred to our urology clinic due to vague abdominal pain and hematuria. Computed tomography (CT) without contrast material visualized an ectopic kidney in the left iliac fossa with a complete staghorn stone. Under general anesthesia, operation was done in supine position with a gentle lateral elevation on the right side. The surgeon stands on the right side of the patient. First, a 12 mm port was inserted at the umbilicus using the Hasson technique. After creation of pneumoperitoneum, operation was done by three 5 mm trocars were arranges as paraumbilical, the point between umbilicus and inguinal canal at left and right side...

INTRODUCTION AND OBJECTIVES: Stone formers often have a chronic exposure to significant quantities of ionising radiation from radiological investigations and interventions. Predicting radiation exposure would allow the clinician to quantify expected cumulative radiation and find strategies to minimise exposure. We evaluated radiation exposure during ureteroscopy and laser lithotripsy (URS + LL) for a single stone episode and correlated the results to stone characteristics. METHOD: Data was collected retrospectively for all patients undergoing URS + LL in our institution over a 1 year period...

BACKGROUND: Minimally invasive procedures have become the standard option for treatment of urinary stones; the use of more invasive techniques is not a common practice currently. This emergent technology is not always available and laparoscopy is the alternative option. There are few reports of laparoscopic management for urinary lithiasis in pediatric patients. This study is about the use of laparoscopic surgery combined with pyeloscopy as a feasible first-line treatment for pediatric urolithiasis in renal and proximal ureteral locations...

Background: Percutaneous nephrolithotomy (PCNL) is a procedure typically performed under general anesthesia (GA); however, many patients might be considered unfit for GA and locoregional anesthesia is their only chance to have the procedure done. Case Presentation: A 60-year-old Middle-Eastern female with end-stage lung disease underwent evaluation for lung transplant; she was found to have severe restrictive pattern on steroid and continuous oxygen therapy, pulmonary hypertension with dilated right ventricle, chronic anemia, and asthma...

RELEVANCE: Management of patients with large and staghorn stones of a solitary kidney is widely debated among urologists and has not been sufficiently investigated, which determined the relevance of this study. MATERIALS AND METHODS: The study comprised 80 patients with large (>20 mm) and staghorn stones of an anatomically or functionally solitary kidney. Of them, 58 patients underwent percutaneous nephrolithotripsy (PNL), and 22 had open surgery. The criterion of the treatment effectiveness was the complete stone clearance or small residual fragments sized less than 3 mm...

OBJECTIVE: To evaluate the effect of prepuncture on the double-tract percutaneous nephrolithotomy (PCNL) under ultrasound guidance for renal staghorn calculi. METHOD: Double-tract or even multi-tract is necessary for the treatment of staghorn calculi. However, intraoperative injury, exudation, bleeding, and influence of original tract might lead to difficulty in second puncture, thus prolonging operating time, and even lead to puncture failure. We retrospectively reviewed the records of 178 patients with renal staghorn calculi who received double-tract PCNL in our department...

INTRODUCTION: Struvite stones account for 15% of urinary calculi and are typically associated with urease-producing urinary tract infections and carry significant morbidity. This study aims to characterize struvite stones based on purity of stone composition, bacterial speciation, risk factors, and clinical features. METHODS: Retrospective data was collected from patients diagnosed with infection stones between 2008 and 2012. Stone analysis, perioperative urine cultures, bacterial speciation, and clinical data were collected and analyzed...

During the excavation of the 19th century Peoria City Cemetery (Peoria, Illinois), a skeleton of a female, aged 20-30 years old, was found with large, bilateral calcified masses in the abdominal region. The masses were analyzed by Fourier transform infrared (FTIR) spectroscopy, and the results compared to published clinical data in an effort to determine the etiology of the stones. The calcified masses were determined to be staghorn struvite uroliths, which commonly result from chronic urinary tract infection and likely impacted the overall health of this individual...
