The ureteroscopic approach to ureteral strictures has diminished morbidity because of smaller-caliber equipment, improved optics, Ho:YAG laser, and a better understanding of the risk factors for ureteral strictures. Direct visualization by means of retrograde ureteroscopy provides a safe and effective approach to treat ureteral strictures without the need for an open incision or percutaneous nephrostomy access. All patients with a ureteral stricture require an extensive evaluation and planning before treatment. Generally, patients with ureteral strictures and a history of carcinoma should undergo biopsy of the area of stricture. With recurrent cancer, patients may present with pain, nausea, vomiting, pyelonephritis, or loss of the ipsilateral renal unit. Malignant strictures tend to not respond well to balloon dilation alone. Open or laparoscopic resection and reconstruction may be indicated if there is a chance for cure. In patients who are not good surgical candidates or in those who have advanced disease, the urologist is left with the option of an indwelling stent or nephrostomy tube.

There are approximately 250,000 cases of acute pyelonephritis each year, resulting in more than 100,000 hospitalizations. The most common etiologic cause is infection with Escherichia coli. The combination of the leukocyte esterase test and the nitrite test (with either test proving positive) has a sensitivity of 75 to 84 percent and a specificity of 82 to 98 percent for urinary tract infection. Urine cultures are positive in 90 percent of patients with acute pyelonephritis, and cultures should be obtained before antibiotic therapy is initiated. The use of blood cultures should be reserved for patients with an uncertain diagnosis, those who are immunocompromised, and those who are suspected of having hematogenous infections. Outpatient oral antibiotic therapy with a fluoroquinolone is successful in most patients with mild uncomplicated pyelonephritis. Other effective alternatives include extended-spectrum penicillins, amoxicillin-clavulanate potassium, cephalosporins, and trimethoprim-sulfamethoxazole. Indications for inpatient treatment include complicated infections, sepsis, persistent vomiting, failed outpatient treatment, or extremes of age. In hospitalized patients, intravenous treatment is recommended with a fluoroquinolone, aminoglycoside with or without ampicillin, or a third-generation cephalosporin. The standard duration of therapy is seven to 14 days. Urine culture should be repeated one to two weeks after completion of antibiotic therapy. Treatment failure may be caused by resistant organisms, underlying anatomic/functional abnormalities, or immunosuppressed states. Lack of response should prompt repeat blood and urine cultures and, possibly, imaging studies. A change in antibiotics or surgical intervention may be required.

Urinary tract infection (UTI) is one of the most common childhood bacterial infections, after upper respiratory tract and middle ear infections. The current goal of management is to prevent detrimental effects of UTI by early detection and treatment. Recommendations for the imaging of children depend upon age at presentation and sex. All children aged <5 years who have had a febrile UTI require a radiologic evaluation to identify any underlying genitourinary pathology. Older children can undergo a more tailored work-up depending on whether there is a febrile UTI or cystitis-type symptoms. Dysfunctional voiding and urge syndrome significantly increase the risk of developing UTIs in children. Vesicoureteral reflux can increase the risk of pyelonephritis and renal scarring in children with UTIs. For the most part, pyelonephritis can be diagnosed on clinical grounds in the majority of patients and a subsequent (99m)Tc-dimercaptosuccinic acid scan can be reserved to identify post-nephritic renal scarring. When renal scarring is identified, the child and parents need to be educated regarding the possibility of hypertension, proteinuria, progressive nephropathy, and the risk of complications in future pregnancies. Treatment of UTI is started in the unwell child before the culture results are available and subsequently changed to culture-specific antimicrobial therapy. A short course of treatment is required for acute uncomplicated UTIs. A child with acute pyelonephritis requires 10-14 days of antibacterial treatment. The oral route in young children often causes vomiting, which implies therapeutic delay, a well known risk factor for scarring.

Aortic dissection is a life-threatening illness requiring early diagnosis and treatment. Uncommon early presentations mimicking various illnesses can delay diagnosis. This case study describes a 44-year-old woman with type B aortic dissection initially presenting as acute pyelonephritis (APN). Early clinical manifestations were sudden onset of left flank pain, fever, hematuria and pyuria, and following admission, severe abdominal pain, nausea, vomiting, reduced urine output and renal function deterioration. Abdominal computed tomography showed type B aortic dissection complicated with a small bowel infarct, ischemic ascending colon and left renal infarct. Emergency surgical interventions of small bowel resection, ileoduodenostomy and cholecystectomy were performed; a second laparotomy was subsequently performed for anastomosis leakage. The patient died due to septic shock with multiorgan failure. Aortic dissection initially mimicking APN is rare. Accurate early diagnosis of aortic dissection with indeterminate presentation is crucial. Early surgical intervention for visceral organ ischemia is important to preventing morbidity and mortality.

Bilateral emphysematous pyelonephritis is a rare life-threatening condition affecting almost exclusively patients with diabetes mellitus. Symptoms, which include fever, chills, abdominal and flank pain, nausea, vomiting, dysuria and pyuria, usually mimic those of classic pyelonephritis, and thus clinical suspicion for this urgent condition should be raised in every diabetic patient with similar presentation. Computed tomography (CT) remains the gold standard for the diagnosis demonstrating gas in the renal parenchyma, collecting system or perinephric tissue. Treatment, which should be aggressive, is classically surgical, and early nephrectomy is recommended. Percutaneous drainage associated with medical treatment might be an alternative. Successful exclusively medical treatment has been described but is infrequent and is reserved as an alternative for patients in whom surgical intervention is contraindicated. We report a case of bilateral emphysematous pyelonephritis in an 82-year-old female diabetic patient who presented with symptoms of typical pyelonephritis. Diagnosis was confirmed by CT, and Escherichia coli was identified as the causative factor. The patient was successfully treated medically with intravenous administration of cefepime and amikacin for 14 days and recovered fully. The therapeutical options for this severe but rare condition are discussed.

Four studies, including two being published as an abstract, have recently demonstrated the feasibility of oral treatment of pyelonephritis in children, with no increased risk of treatment failure, early urinary tract re-infection, or renal scars. To do so, the pediatrician must ensure that: (1) the patient does not appear toxic, has no vomiting; (2) there is no known severe obstructive or refluxing uropathy and (3) parents are deemed to be adherent to the treatment. If these criteria are fulfilled, the pediatrician can start an oral treatment with a 3rd generation cephalosporine for 10 to 14 days. Ambulatory follow-up is crucial, and persistance of fever after 3 days is a reason for a new outpatient visit, additional or supplementary imaging studies (renal ultrasonography) and eventually a switch to intravenous treatment.

Renal angiomyolipoma is a distinctive benign neoplasm that occurs either sporadically or in patients with tuberous sclerosis complex. A 45-year-old woman was admitted with history offlank pain and vomiting. There were no signs suggestive of tuberous sclerosis either in the patient or her family. At operation, she had a left renal mass with nephrolithiasis and hydronephrosis. Histopathology revealed epithelioid angiomyolipoma of the left kidney with chronic pyelonephritis. Immunohistochemistry confirmed the diagnosis of angiomyolipoma. This case is presented to highlight the epithelioid variant of angiomyolipoma which may behave in an aggressive manner.

We report two cases of acute renal failure in patients with nonfulminant acute hepatitis A. First case is a healthy 25 year-old man complained of myalgia and jaundice. Initial laboratory results showed BUN 40 mg/dL, creatinine 5.23 mg/dL, AST 2,220 IU/L, ALT 3,530 IU/L, total bilirubin 6.26 mg/dL, and positive anti-HAV IgM antibody. Supportive treatments including fluid therapy were started. Serum creatinine and total bilirubin levels were 7.98 mg/dL and 7.66 mg/dL respectively on the 5th hospital day, and decreased gradually. He was discharged on the 12th hospital day, and was being followed up in outpatient department. Second case is a 33 year-old woman who admitted for bilateral flank pain, high fever, nausea, and vomiting. She was diagnosed as acute pyelonephritis and acute hepatitis A. On admission, BUN 13 mg/dL, creatinine 0.74 mg/dL, AST 3,720 IU/L, ALT 2,280 IU/L, total bilirubin 0.9 mg/dL were noted, and acute renal failure developed next day. Fluid therapy with antibiotics administration were started, and maximal BUN and creatinine was 41.7 and 8.09 mg/dL respectively on the 8th day. She recovered without dialysis and was discharged on the 19th hospital day. Proper and prompt comprehensive supportive measures would decrease the need for dialysis in patient of acute renal failue associated with acute hepatitis A.

Emphysematous pyelonephritis (EPN) is a serious and often life-threatening condition due to a gas-producing and necrotizing infection involving the renal parenchyma and perirenal tissue. The infection is almost exclusively seen in diabetic patients, and the main feature of its presence is finding gas within the kidney. Patients usually present with fever, chills, flank pain, and dysuria. Laboratory testing usually reveals hyperglycemia, leukocytosis, pyuria, an elevated blood urea nitrogen (BUN) level, and high serum creatinine level. Other, nonspecific symptoms such as abdominal pain, nausea, vomiting, and diarrhea can accompany acute pyelonephritis, as found in the reported case. The appropriate management of such serious infection requires combined medical and surgical treatment. In severe infection, nephrectomy should not be delayed. We report a case of EPN in a diabetic patient who presented with gastrointestinal symptoms. A high index of suspicion, coupled with a good imaging study [preferably computed tomography (CT) scanning] of the abdomen can lead to early diagnosis. Appropriate medical and surgical management have resulted in a successful outcome.

Ovarian vein thrombosis (OVT) is a rare cause of abdominal pain that may mimic a surgical abdomen. The differential diagnosis of OVT includes acute appendicitis, endometritis, pelvic inflammatory disease, pyelonephritis, nephrolithiasis, tubo-ovarian abscess, and ovarian torsion. The complications of OVT, including sepsis and pulmonary embolism, are significant. Diagnosis relies on a careful examination of the radiographic findings. This diagnosis should be considered not only in postpartum patients but also in women with pelvic inflammatory disease, recent abdominal surgery, malignancy, or known hypercoagulable state. In this report we present a case of OVT in a 29-year-old woman presenting with 3 days of sharp left-sided abdominal pain, nausea, and vomiting after bilateral salpingectomy. We then discuss the epidemiology, pathophysiology, and clinical management of OVT.
