Bilateral hydronephrosis secondary to urinary obstruction leads to a buildup of back pressure in the urinary tract and may lead to impairment of renal function. We present a case of a 57-year-old male with a history of alcoholic liver cirrhosis, who presented with tense ascites and acute renal failure. Bilateral hydronephrosis was seen on abdominal ultrasound. Multiple large-volume paracenteses...

Laboratory mice develop naturally occurring lesions that affect biomedical research. Hydronephrosis is a recognized pathologic abnormality of the mouse kidney. Acquired hydronephrosis can affect any mouse, as it is caused by any naturally occurring disease that impairs free urine flow. Many etiologies leading to this condition are of particular significance to aging mice. Non-invasive ultrasoun...

Objectives: To describe the maternal and fetal characteristics of isolated antenatal hydronephrosis (ANH), to address parental concerns by providing local data based on the fetal renal pelvis anteroposterior diameter (APD), and to determine the most effective APD cutoff in the second and third trimester for prediction of postnatal urological outcome. Methods: A retrospective review of all cases...

STUDY OBJECTIVE Hydronephrosis is readily visible on ultrasonography and is a strong predictor of ureteral stones, but ultrasonography is a user-dependent technology and the test characteristics of clinician-performed ultrasonography for hydronephrosis are incompletely characterized, as is the effect of ultrasound fellowship training on predictive accuracy. We seek to determine the test charact...

Parapelvic cysts are uncommon conditions that are usually found during autopsy. Their ultrasonographic appearance is similar to hydronephrosis. We report the case of a 46-year-old female with a 4-year history of vague flank pain and a previous history of bilateral moderate hydronephrosis. The patient was investigated by ultrasonography and non-enhanced CT scan, and finally diagnosed as bilatera...

Patients with vesicoureteral reflux (VUR), the retrograde flow of urine from bladder to kidney, are known experience renal scarring; this results in worsening function. Reflux nephropathy is a cause chronic kidney disease, and VUR has also been observed dialysis patients. major underlying precursor condition urinary tract infection (UTI) sometimes accompanied by hydronephrosis. However, there n...

AIMS The current study aims to assess the role of ultrasound (US) parameters in explaining the variance of hydronephrosis grades in reno-urinary anomalies, as well as their performance in quantifying the incidence of patients with uropathies. METHODS In this study 196 patients were prospectively included. All of them had renal/urinary tract anomalies and were recruited from 5992 US examined h...

Congenital obstructive nephropathy is the primary cause of chronic renal failure in children. Disorders of mitochondrial energy metabolism may be a primary factor underlying tubular cell apoptosis in hydronephrosis. The β-F1-ATPase (ATP5B) and electron transfer flavoprotein β subunit (ETFB) metabolic markers are involved in mitochondrial energy metabolism in other diseases. The aim of the prese...

PURPOSE To investigate hydronephrosis after the establishment of tubeless cutaneous ureterostomy by using our definition of the tubeless condition and our indications for catheter insertion. MATERIALS AND METHODS Twenty-eight (54 renal units) patients with both establishment of tubeless cutaneous ureterostomy 3 months after surgery and at least 12 months of follow-up were investigated in this...

A 77-year old woman visited the emergency room (ER) because of abdominal pain and severe diarrhea. She had undergone radiation therapy for cervical cancer 30 years earlier. Pertinent initial laboratory data included a serum urea nitrogen level of 90.9 mg/dL and a creatinine level of 4.1 mg/dL. Sigmoidoscopy showed circular ulceration with whitish exudates consistent with ischemic colitis in the...
