We describe a 40-year-old living-donor renal-transplant recipient who underwent successful ureterolithotripsy. He had been on hemodialysis for >15 years pre-transplant and underwent ureteroureterostomy along with the surgery. One year post-transplant, ultrasound examination demonstrated hydronephrosis, and CT showed a 6-mm ureteral calculus at the ureteroureterostomy site. No pain and no elevated serum creatinine were present. As the ureter was easily accessed, we performed a ureterolithotripsy, which would confirm whether a suture caused the calculus...

INTRODUCTION: A precise puncture of the renal collecting system is the most essential step for percutaneous nephrolithotomy (PCNL). There are many techniques describing this crucial first step in PCNL including the bull's eye technique, triangulation technique, free-hand technique, and gradual descensus technique. We describe a novel puncture guide to assist accurate percutaneous needle placement during bull's eye technique. METHODS: The mini access guide (MAG) stabilizes the initial puncture needle by mounting it on an adjustable multidirectional carrier fixed to the patient's skin, which aids in achieving the "bull's eye" puncture...

Crossed fused ectopic kidney is an unusual congenital malformation of the urinary tract. This condition is usually identified in the autopsy specimen rather than in general clinical scenario. In this condition, both kidneys are located on one side of the midline and are fused with each other. This condition is generally asymptomatic and usually diagnosed as incidental finding. We came across a case of crossed fused left to right ectopia with inferior infusion with nephroptosis. Generally, in cases of crossed fused renal ectopia, one kidney is lower than the other one but in our report, both kidneys were present at the same level...

Background: Actinomycosis is a condition in which Actinomyces, a normal component of the oral and gastrointenstial flora, becomes pathogenic in the setting of damaged tissue, leading to widespread tissue destruction across fascial planes. Prior literature describing this condition is rare, particularly cases involving the retroperitoneum. In this study, we report a case of retroperitoneal actinomycosis caused by an infected, obstructing ureteral stone. Case Presentation: A 48-year-old woman with a history of substance abuse, malnutrition, and gastric bypass presented to the emergency room with a 3-week history of abdominal pain and fevers...

Bilateral hydroureteronephrosis involves the dilatation of the renal pelvis, calyces and ureter; it develops secondary to urinary tract obstruction and leads to a build-up of back pressure in the urinary tract, and it may lead to impairment of renal function and ultimately culminate in renal failure. Although clinically silent in most cases, it can be diagnosed as an incidental finding during evaluation of an unrelated cause. In a minority of patients, it presents with signs and symptoms. Renal calculus is the most common cause, but there are multiple non-calculus aetiologies, and they depend on age and sex...

The ureterocele is an uncommon congenital anomaly of the lower ureter. Ureterocele with a single pelvicalyceal system, bilateral, and orthotopic variety is less common. Calculi within bilateral ureterocele are a rare occurrence. To the best of our knowledge, only a few similar cases have been reported in the literature. Among the all reported presentations of this type of ureterocele, presentation with Acute Urinary Retention (AUR) has not been described in the literature. We present a case of nine-year-old child having bilateral, single system orthotopic ureterocele with calculi in bilateral ureterocele and presented with AUR due to obstructive bulbar urethral calculus...

BACKGROUND: Uric acid is the metabolic end product of purine metabolism in humans. Altered serum and urine uric acid level (both above and below the reference ranges) is an indispensable marker in detecting rare inborn errors of metabolism. We describe different case scenarios of 4 Sri Lankan patients related to abnormal uric acid levels in blood and urine. CASE 1: A one-and-half-year-old boy was investigated for haematuria and a calculus in the bladder. Xanthine crystals were seen in microscopic examination of urine sediment...

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.
