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...

Simple hepatic cysts are common and most often asymptomatic. In symptomatic cases, hemorrhage, rupture, and infection are major complications. However, urinary tract obstruction caused by a simple hepatic cyst is rare. We treated an 82-year-old Japanese man with an infected giant hepatic cyst causing right hydronephrosis who had a past history of left nephrectomy for renal cell carcinoma. The p...

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. Cases of giant hydronephrosis are rare and usually contain no more than 1-2 litres of fluid in the collecting system. Here, we report a rarely seen case with giant urinary bladder and bilateral giant hydronephrosis due to bladder neck o...

Duplex collecting system of the kidney is a common congenital anomaly urinary tract. It usually asymptomatic clinically with normal renal function. In rare instances, it may complicate giant hydronephrosis. The following case middle aged woman history recurrent tract infections (UTI) and flank pain diagnosed bilateral partial duplex complicated unusual non-functioning lower moiety left hydronep...

We performed a prospective study of patients with suspected ureteral colic to evaluate the test characteristics of bedside renal ultrasonography (US) performed by emergency physicians (EPs) for detecting hydronephrosis, and to evaluate how US can be used to predict the likelihood of nephrolithiasis. Thirteen EPs performed US, recorded the presence of hydronephrosis, and made an assessment of th...

Nephrogenic diabetes insipidus (NDI) can cause nonobstructive hydronephrosis. Congenital NDI (CNDI) is caused by a genetic mutation. This case report presents a 12-year-old girl who was incidentally diagnosed with nonobstructive hydronephrosis due to NDI caused by AQP2 gene mutation after being evaluated for microscopic hematuria found on routine health examination at school. The patient’s medi...

Background Renal colic is a common emergency department presentation. Hydronephrosis is indirect sign of urinary obstruction which may be due to obstructing ureteric calculus and can be detected easily by bedside ultrasound with minimal training. Objective To compare the accuracy of detection of hydronephrosis performed by the emergency physician with that of radiologist's in suspected renal co...
