OBJECTIVES: To present the safety and efficacy of fluoroscopy-free ultrasound-guided PCNL for the treatment of renal calculi in pediatric patients of all ages. METHODS: 30 children with mean age of 5 years (6 months-12 years) underwent totally ultrasound-guided PCNL from March 2013 to August 2016. The pyelocalyceal system was punctured in prone position using only ultrasonography guidance, and the tract was dilated using a single shot dilation technique. No fluoroscopy was used during any of the stages of renal access...

Introduction: Percutaneous nephrolithotomy (PCNL) is traditionally performed with the patient in the prone position for large renal calculi. However, anesthetic limitations exist with the prone position. Similarly, the supine position is associated with poorer ergonomics due to the awkward downward position of the renal tract, a smaller window for percutaneous puncture, and a higher risk of anterior calyx puncture. This study aimed to demonstrate the feasibility and safety of lateral-PCNL in managing large renal calculi without the disadvantages of prone and supine positions...

Conventionally, patients suffered from recurrent common bile duct (CBD) stone after cholecystectomy are suggested to be treated with endoscopic retrograde cholangiopancreaticography. This study was designed to explore the feasibility of laparoscopic common bile duct exploration (LCBDE) as a salvage procedure for recurrent CBD calculi after cholecystectomy. A retrospective review was conducted of data from 65 patients who underwent LCBDE for recurrent CBD calculi after cholecystectomy from January 2011 to July 2015...

Cholelithiasis is a major cause of morbidity worldwide. The incidence of gall stone in children in Pakistan has not been sufficiently studied and is increasingly being detected: the reason may be a true rise in the incidence or an improvement in diagnosis due to liberal use of diagnostic facilities and thus the increased opportunity to detect disease. A healthy 2 years and 2 months old male child presented to outpatient with history of recurrent attacks of pain abdomen and anorexia. Ultrasonography showed a 0...

INTRODUCTION: Urinary lithiasis is a recurrent disease defined by the presence of calculi in the urinary tract. Most urinary calculi have as a major component calcium oxalate which occurs mainly in two crystalline forms: Calcium oxalate monohydrate (whewellite) and calcium oxalate dihydrate (weddellite). The target behind, this work is to study the inhibiting effect of the calcium oxalate's crystallization by the extract of the Ammi visnaga and the Punica granatum. METHODS: The inhibition of crystallization has been studied in vitro with both the absence and the presence of the different concentrations of the extracts of the two plants...

Bladder calculi occur in female is uncommon and the evaluation of bladder stone in women with any history of previous pelvic surgery demands careful attention. Bladder erosion due to previous anti-incontinence surgery formed the nidus for stone formation, and often presented as recurrent cystitis or refractory urinary incontinence since the early postoperative period. We hereby reported a rarely delayed appearance of the symptomatic iatrogenic bladder stone occurred 10 years after previous tension-free vaginal tape procedure...

The objective of this meta-analysis was to evaluate the association between a history of urinary calculi (UC) and the risk of bladder cancer (BC). A literature search was performed from inception until July 2017. Studies that reported odds ratios (OR), relative risks or hazard ratios comparing the risk of BC in patients with the history of UC vs those without the history of UC were included. Pooled odds ratios and 95% confidence interval (CI) were calculated using a random-effect or fixed-effect method. Thirteen studies were included in our analysis to assess the association between a history of UC and risk of BC...

PURPOSE: The Sepsis-3 Task Force proposed a new definition of sepsis based on SOFA and introduced a novel scoring system, qSOFA, for screening high-risk patients for sepsis. Their clinical usefulness, however, is unclear. Therefore, we investigated their predictive performance for mortality in APN-UTC patients. MATERIALS AND METHODS: This retrospective study included 141 consecutive patients clinically diagnosed with APN-UTC outside the ICU. We evaluated the performance of qSOFA, SOFA, and SIRS in predicting in-hospital mortality and ICU admission using the AUC of the ROC curve, NRI, IDI, and decision curve analysis...

Heterotrophic bone formation in the pelvicalyceal system acting as a nidus for stone formation is a rare phenomenon. We report a case of a 16 years old female who, during percutaneous nephrolithotomy for right renal calculi, was found to have bone attached to the renal pelvic epithelium over which stone formation had occurred.

Background: Vaginal stones are rare and often unknown entities. Most urologists may never see a case in their careers. Case Presentation: We present the case of a 34-year-old bedridden Caucasian woman with mental and physical disabilities who presented with a large primary vaginal calculus, which, surprisingly, had remained undiagnosed until the patient suffered a right renal colic caused by a ureteral stone. The vagina was completely filled and a digital examination was not possible. For this reason, the stone was removed using surgical pliers with some maneuvering...

We report the case of a 23-year-old woman treated by mesalazine for ulcerative colitis and who subsequently presented recurrent renal colic due to mesalazine urinary stones. This is the second case described in the literature.Mesalazine stones are soft, friable and have an orange-beige color. They are not visible on non-contrast computed tomography (CT). Their diagnosis is based on morpho-constitutional analysis and CT-urography. Patients treatedby mesalazine who present renal colic should undergo CT-urography in order to make the diagnosis...

PURPOSE: The paper focuses on the relationship of risk factors and metabolic disorders with mineralogical composition of calculi, age and gender of calcium oxalate stone formers. MATERIALS AND METHODS: Stone mineralogical composition, 24 hour biochemistry and pH-profile of urine were examined for sixty four stone formers using powder X-ray diffraction, spectrophotometric and potentiometric techniques. RESULTS: The analysis indicated that 44 % of calculi were composed of pure calcium oxalate monohydrate, whereas other 56 % contained both monohydrate and dihydrate or usually their mixtures with hydroxyl apatite...

INTRODUCTION: Urolithiasis is a globally-distributed disease; however, its prevalence varies across countries and regions. Countries in the Middle East have been reported to have particularly high nephrolithiasis prevalence rates. To date, however, we have an incomplete understanding of the composition of stones seen in this region. Therefore, we performed a study to characterize stone composition over a 14-year period in the Eastern Province of the Kingdom of Saudi Arabia (KSA). MATERIALS AND METHODS: A retrospective review of all adult patients who had the composition of their upper urinary tract calculi analyzed at Johns Hopkins Aramco Healthcare (JHAH) between 1999 and 2013 was performed...
