INTRODUCTION: Renal papillary necrosis is not commonly seen in daily practice, but can have severe consequences when it is not diagnosed in time. It is known to be associated with sickle cell hemoglobinopathies; however a wide range of etiologies are possible, and it is therefore not the first diagnosis clinicians consider in patients with sickle cell disease who present with hematuria. METHODS: A literature search was performed to summarize the current knowledge about renal papillary necrosis associated with sickle cell disease...

INTRODUCTION: Pediatric presentations of a prostatic utricle have received only scant attention. Though recognized with increased frequency in boys with hypospadias, little is described about their incidence and potential for morbidity in boys with normal external genitalia. METHODS: We initially reviewed a cohort of 64 patients with hypospadias seen over a 3-year period to determine the frequency of investigative lower urinary tract studies and utricle identification...

BACKGROUND: Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN) are devastating hypersensitivity disorders that cause epidermal cell death and can affect all epidermal surfaces, including the urethra, vagina, labial and scrotal skin. Despite the well-described ocular and orofacial manifestations of SJS/TEN, there is a paucity of reports on the genitourinary (GU) symptoms and their management. Specifically, consulting services often ask the pediatric urology team if it is safe to place a urethral catheter, but there is no data in the literature to help guide management...

Impacted stones frequently cause changes in the ureter, including edema of the ureteral wall, stone embedding in the ureteral mucosa or ureteral bending, which often preclude spontaneous passing of the stone and increase the risk of complications during surgery. When stone impaction is suspected preoperatively, management should be adapted accordingly. However, surgical treatment strategies remain controversial in pediatric patients because of the scarcity of cases reported. We describe the case of a 2-year-old girl with a right impacted ureteral stone who presented with gross hematuria and pyuria, but no metabolic risk factors or hematological abnormalities...

Although proteinuria is usually benign in the form of transient or orthostatic proteinuria, persistent proteinuria may be associated with more serious renal diseases. Proteinuria may be an independent risk factor for the progression of chronic kidney disease in children. Mechanisms of proteinuria can be categorized as glomerular, tubular, secretory, or overflow. A history, a physical examination, and laboratory tests help determine the cause. Transient (functional) proteinuria is temporary. It can occur with fever, exercise, stress, or cold exposure, and it resolves when the inciting factor is removed...

Pyogenic granuloma (PG) is a benign, vascular tumor that is rarely reported in the urinary tract of pediatric population. Herein we present a case of a child followed up for recurrent painless macroscopic hematuria. We performed ureteroscopy, and a whitish lesion was discovered in the upper calyx of the right kidney. The lesion resected endoscopically, and microscopic examination of the lesion was consistent with PG. It is important for pediatricians and urologists to properly recognize PG as a possible source of hematuria in the pediatric population...

INTRODUCTION: Percutaneous nephrolithotomy (PCNL) has undergone significant changes in recent years in the quest for improving efficacy and reducing morbidity. Newer minimally-invasive modalities of PCNL such as mini-PCNL, ultra-mini PCNL, and micro-PCNL have evolved with advancement in optics and technology. However, with these newer advancements, migration of small fragments produced with laser lithotripsy remains a concern, which may result in incomplete stone clearance. We describe a new technique of PCNL termed "Superperc", that utilizes suction to remove all the fragments and maintain one-way flow...

Nephrogenic adenoma (NA) is a rarely seen benign metaplastic lesion of the urinary tract. Its etiology is uncertain, but induced by chronic inflammation, irritation, and trauma. NA is located in the urinary tract, most commonly in the bladder. NA usually presents with hematuria and lower urinary tract symptoms. In the literature it is mostly seen in adults but about 30 cases of NA's have been reported in children. Treatment of intravesical lesions consists of transurethral resection (TUR) and fulguration and rarely partial or total cystectomy may be required in ineffective TUR...

Thyroid storm has a high mortality rate and is often associated with a precipitating factor such as intercurrent illness or infection. It is rare in pediatric patients. Cardiac disease in hyperthyroidism mostly manifests itself as tachycardia but more serious cardiac findings have also been described. A 5-year-old male with recent strep throat infection presented with dilated cardiomyopathy, hematuria, and symptoms and lab findings consistent with severe hyperthyroidism. He was diagnosed with thyroid storm secondary to concurrent Graves' disease and poststreptococcal glomerulonephritis (PSGN)...

Wilms tumor (WT) is the most prevalent pediatric renal tumor and most commonly occurs between ages 1 and 5 years. Data are lacking on children younger than 12 months with renal tumors. The cancer registry at the authors' institution was queried to identify patients 12 months and younger with renal masses. Demographics, clinical presentation, histopathology, stage, and survival outcomes were reviewed. The most common presenting symptoms included an asymptomatic abdominal mass (73%) and hematuria (9%). Histopathology revealed WT in 73% of patients, mesoblastic nephroma in 20%...

INTRODUCTION: Nephrolitiasis, once considered an adult disease, has become increasingly prevalent in children, with na increase from 6% to 10 % annually in past 25 years. Kidney stones in pediatric population can result from metabolic diseases in up to 50% of children affected. Other factors associated with litiasis are infection, dietary factors, and anatomic malformations of urinary tract. Standard treatment procedures for pediatric population are similar to adult population. Extracorporeal shock wave lithotripsy (ESWL), ureterorenoscopy (URS), percutaneous nepfrolithotomy (PCNL), as well as laparoscopic and retroperitoneoscopic approaches can be indicated in selected cases...

Despite being a common procedure, percutaneous renal biopsy (PRB) carries the potential for complications. The British Association of Paediatric Nephrologist (BAPN) has published standards for pediatric PRB. As Indian data are scarce, we conducted a prospective audit of 100 consecutive pediatric renal biopsies (60% males) under real-time ultrasound guidance. Nephrotic syndrome was the most common indication for PRB (68%) with minimal change disease (30%) and focal segmental glomerulosclerosis (25%) being the most common histopathological lesions...

Page kidney refers to the occurrence of hypertension secondary to renal compression and is usually associated with a subcapsular or perinephric hematoma. It generally occurs weeks to months after the initial injury. We report on a case of Page kidney occurring acutely after Grade IV blunt renal trauma in a pediatric patient with a solitary kidney following a tobogganing accident. The child was initially managed conservatively and discharged after six days bed-rest. He re-presented post-injury Day 12 with recurrent hematuria, anemia, hypertension, and renal failure that required eventual, and successful, surgical exploration...
