Nephrolithiasis, although a common entity in adults, is less common in children and rare in newborns. The evaluation and management strategies of renal stones in neonates are unclear. We report a rare scenario of renal calculus in a newborn aged 3 days presenting with decreased urine output, fever and crying during micturition. Patient was thoroughly investigated and managed conservatively. Further follow-up showed increase in stone size with recurrent urinary tract infections, hence shock wave lithotripsy was performed to successfully break and clear the stone fragments...

INTRODUCTION: Percutaneous Nephrolithotomy (PCNL) is the treatment modality used for the extraction of large renal stones, or multiple calculi or stones resistant to shock wave lithotripsy. The General Anaesthesia (GA) is the standard modality for PCNL. However, few studies conclude that Spinal Anaesthesia (SA) can be an alternative method of anaesthesia with similar incidence of complications. AIM: In our study we evaluated the feasibility of spinal anaesthesia in terms of intraoperative and postoperative results in patients undergoing PCNL...

Nephropleural fistula following percutaneous nephrolithotomy (PCNL) is a very rare complication and there are only a few case reports available in the literature. We present a case of a 65-year-old male patient with a right staghorn renal calculus and a left upper ureteric calculus who developed a right nephropleural fistula following right-sided PCNL. The patient required intercostal tube drainage. The cause of the fistula was identified to be a superior calyceal infundibular obstruction due to tiny residual stone fragments and oedema, which was endoscopically dilated, and the fistula subsequently healed...

An in-depth comprehension of the epidemiology as well as pathophysiology of uric acid urolithiasis is important for the identification, treatment, and prophylaxis of calculi in these patients. Persistently low urinary pH, hyperuricosuria, and low urinary volume are the most important factors in pathogenesis of uric acid urolithiasis. Other various causes of calculus formation comprises of chronic diarrhea, renal hyperuricosuria, insulin resistance, primary gout, extra purine in the diet, neoplastic syndromes, and congenital hyperuricemia...

Here, we reported our clinical application of ureterorenoscope (URS) and flexible URS lithotripsy in stone removal on 10 cases of excised living donor kidney graft. After the extraction of donor kidney by retroperitoneal laparoscopy, the donor graft was perfused with 4 °C HCA solution. Calculus between 2-4 mm were removed intact with lithotomy forceps under direct vision of URS. Larger calculi of >4 mm were fractured with flexible URS combining holmium laser lithotripsy. Fragments of the calculus were extracted with basket extractor and lithotomy forceps...

REVIEW
Nicholas Fulton, Prabhakar Rajiah
Detector-based spectral computed tomography (SDCT) is a recently introduced technology that uses a single x-ray tube and 2 layers of detectors to simultaneously collect low- and high-energy data. In this article, we provide an overview of this novel SDCT technology in abdominal imaging. Several applications of SDCT in abdominal imaging are discussed and illustrated, along with a brief description of current literature on the status of dual-energy computed tomography in these applications. This includes urinary calculus composition, characterization of masses (renal, adrenal, hepatic, and others), tumor perfusion, improving vascular contrast, improving lesion conspicuity, decreasing artifacts, and reducing radiation dose...

Prostatic parenchymal calculi are common in ageing men who are evaluated for benign prostatic hyperplasia or prostate cancer. Giant prostatic calculi are very rare, usually associated with local predisposing factors for urinary stasis and infections, and traditionally managed by open surgery. We present the first case of its kind to be associated with a concurrent staghorn nephrolithiasis, and removed successfully by endoscopic approach using an access sheath through the urethra.

A duplex ureter constitutes about 1% of the renal tract anomalies.A 39-year-old man presented with a 4-week history of left loin pain and microscopic haematuria. Investigation with a non-contrast CT KUB revealed a 6 mm non-obstructing calculus in the left distal ureter.Left ureteroscopy and lithotripsy was planned. However, ureteroscopy failed to identify the calculus. A double J ureteric stent was left in situ and the procedure abandoned in favour of further assessment with a CT urogram. Imaging surprisingly showed a left duplex ureter with the calculus in the non-stented ureter...

INTRODUCTION: Early data support the use of medical expulsive therapy (MET) in children. However, little is known regarding use or outcomes associated with MET outside of pediatric-specific practices. Using a national administrative dataset, we sought to characterize utilization patterns of MET as well as assess outcomes associated with MET exposure. STUDY DESIGN: We interrogated the MarketScan Commercial Claims and Encounters database to identify children under the age of 18 presenting to the emergency department (ED) with any diagnosis of upper urinary tract calculi (UUTC, including renal and ureteral calculi)...

Silicate urolithiasis is rare in humans (0.2%) but common in herbivorous animals. We report a previously unreported instance in India where a pediatric patient with renal pelvic calculus who underwent percutaneous nephrolithotomy was found to have silicate urolithiasis on stone analysis. Retrospective analysis did not reveal any risk factors associated with silicate stone formation.
