A fifty-nine year-old male was hospitalized for exacerbation of chronic pancreatitis. As a gigantic cyst of the pancreatic tail was identified, it was fused with the jejunal loop. Due to persistent fever and severe symptoms in the storage and voiding phases, the patient was referred to a urologist. Because transrectal ultrasound examination revealed a fluid collection resembling the left seminal vesicle filled with purulent material, a transrectal puncture procedure was performed. The analysis of computed tomography scans led to the diagnosis of duplicated collecting system of the left kidney with the enormous ureter of the upper moiety that entered the prostate gland...

Background: Fibroepithelial polyps of the urothelial system are rare and are considered to be benign tumors. Ultrasonography (USG), contrast-enhanced CT, and contrast-enhanced MRI can be used for detecting fibroepithelial polyps in the urothelial system. These polyps can be treated by performing open exploration and endoscopic or laparoscopic resection. Previous studies have also reported the frequent use of laser treatment for treating fibroepithelial polyps located in the proximal ureter. Case Presentation: A 54-year-old female patient presented to our clinic with right flank pain...

RATIONALE: Mucinous tubular and spindle cell carcinoma (MTSCC) is a variant of renal cell carcinoma newly added to the WHO classification in 2004. It is a rare variant of renal cell carcinoma and sometimes it is not easy to distinguish MTSCC from papillary renal cell carcinoma, chromophobe renal cell cancer, etc. The prognosis of MTSCC is favorable after surgical resection. PATIENT CONCERNS: A 45-year-old male patient presented with a right renal mass that was detected on ultrasonography incidentally...

Background: Seminal vesicle cyst is an extremely rare condition, which is frequently congenital and associated with Zinner's syndrome. This syndrome represents a constellation of seminal vesicle cyst, ipsilateral or contralateral renal agenesis or renal dysplasia, ureteral ectopia, and ejaculatory duct obstruction. We report a young symptomatic patient undergoing robot-assisted laparoscopic excision of a huge seminal vesicle cyst during which an atrophic ipsilateral kidney was discovered incidentally and managed by nephroureterectomy in the same session without changing trocar positions...

Acute kidney injury (AKI) most commonly occurs in the hospital setting, and hospital-acquired AKI accounts for 22% of all AKI cases worldwide. AKI causes 2 million deaths per year, and 50% of critically ill patients develop AKI. AKIs include prerenal, intrarenal, and postrenal causes. Treatments include renal replacement therapies and correcting reversible causes. Management of these patients includes medical and social history, laboratory studies, tests such as renal biopsy and ultrasonography, vital signs, volume status, and identifying risk factors...

Renal cancer represents 2% to 3% of all cancers, and its incidence is rising. The increased use of ultrasonography and cross-sectional imaging has resulted in the clinical dilemma of incidentally detected small renal masses (SRMs). SRMs represent a heterogeneous group of tumors that span the full spectrum of metastatic potential, including benign, indolent, and more aggressive tumors. Currently, no composite model or biomarker exists that accurately predicts the diagnosis of kidney cancer before treatment selection, and the use of renal mass biopsy remains controversial...

BACKGROUND: Nephroblastoma (NB) is a malignant embryonal neoplasm derived from nephrogenic blastemal cells. NB usually forms a solid mass, but in extremely rare cases, it may show cystic changes. CASE PRESENTATION: A six-month-old girl with persistent high fevers was found to have pyuria and bacteriuria. Ultrasonography revealed multilocular cysts in the right kidney. Right nephrectomy was performed with cyst wall rupture during surgery. An intraoperative rapid diagnosis, based on peritoneal fluid cytology, confirmed three components of blastemal, stromal, and epithelial cells...

Renal ectopia and fusion anomalies are Congenital Anomalies of the Kidney and the Urinary Tract (CAKUT) that are usually incidentally detected and asymptomatic. Patients affected present a higher risk of complications like recurrent urinary tract infections or obstruction. Pancake kidney (PK) is one of the rarest types of renal anomaly with complete fusion of the superior, mild and inferior poles of both kidneys in the pelvic cavity. Each kidney has its own excretory system with two ureters that do not cross the midline...

AIM: Indigenous Australians have an increased risk of developing Chronic Kidney Disease (CKD). Indigenous women have a higher rate of CKD than men. In a cohort of Indigenous and non-Indigenous preterm neonates, we assessed total renal volume (TRV) (a proxy indicator for nephron number). We hypothesised that there would be no difference in renal volume between these two groups at term corrected (37 weeks gestation). METHODS: Normally grown preterm neonates less than 32 weeks of gestation were recruited and at term corrected dates, the neonates underwent renal ultrasonography (TRV measurements), urine microalbumin-creatinine ratio (ACR) and serum analysis for Cystatin C measurement for eGFR calculation...

BACKGROUND AND OBJECTIVES: Patients are informed of the risk of kidney biopsy-related complications using data from nonhospitalized patients, which may underestimate the risk for hospitalized patients. We evaluated the rate and risk factors of kidney biopsy-related complications in hospitalized patients with acute kidney disease (AKD) to better estimate the risk in this population. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS: We used data from the Yale biopsy cohort to evaluate rates of kidney biopsy-related complications including adjudicated procedure-related bleeding requiring blood transfusions or angiographic interventions, medium- or large-sized hematomas, reimaging after biopsy including abdominal ultrasonography or computed tomography, and death in hospitalized patients with AKD (including AKI)...

Carcinosarcomas are biphasic malignant tumors composed of 2 distinct neoplastic cell populations, epithelial cells and mesenchymal cells. A 13-y-old, female, mixed-breed goat was presented with a 1-wk history of anuria and lethargy. Transabdominal ultrasonography showed an irregular and heterogeneous structure in the region of the bladder and uterus and changes in the echogenicity of both kidneys. Given the poor prognosis, euthanasia was elected. Autopsy revealed a large mass within the uterine cervix and confirmed the changes in the urinary tract...

INTRODUCTION: Increased ultrasonography (US) use has been correlated with an increased incidence of pediatric renal cysts. For simple and stage II cysts, the malignancy risk is low in adulthood, no follow-up is recommended; but there is no consensus on childhood management. Since pediatric renal cysts may be manifestations of hereditary cystic diseases, a different approach and follow-up should be taken for these patients. Herein we present the clinical characteristics and follow-up data of our pediatric patients with simple and stage II renal cysts...

Posterior urethral valves (PUV) are an important cause of paediatric obstructive uropathy. PUV are usually diagnosed by prenatal ultrasonography (US) revealing hydronephrosis and bladder distention. We describe a 17-day-old male infant with abdominal distention who had no hydronephrosis on prenatal US. Laboratory investigations showed serum creatinine of 12 mg/dL, hyperkalaemia and metabolic acidosis. Abdominal US showed large amount of ascites, normal-sized kidneys without hydronephrosis and incompletely distended bladder...
