In order to assess whether it is appropriate and clinically efficient to admit adults with 'clinically diagnosed' acute pyelonephritis (APN) under urologists, as is current practice in many NHS hospitals, a prospective study was undertaken over nine months in an NHS teaching hospital. Thirty-nine patients with clinical APN were admitted to the urology unit; all were pyrexial and 30 (77%) had typical features of rigor, flank pain and irritative lower urinary tract symptoms. Twenty-one (54%) had positive urine cultures, 31 (79%) had parenteral antibiotics, while another three (7%) had oral agents initially. The remaining five (14%) were continued on agents initiated by their GPs before admission. Thirty-three (85%) had imaging procedures with eight significant anomalies being noted. Urgent invasive intervention was required in only four (10%) patients; length of stay varied from one to 25 days. Uncomplicated moderate to severe APN in adults may be treated safely without the need for admission to the urology unit, either in the outpatient setting or on an acute admissions observation ward. Complicated cases requiring intervention can be transferred to the urologist once recommended investigations have been undertaken. This care pathway may help to reduce cancellations of elective urological cases and is likely to be more cost-effective for the NHS by reducing unnecessary admissions.

PURPOSE: To evaluate the indications for and the outcomes of extracorporeal shock wave lithotripsy (ESWL) of calyceal stones <5 mm, we prospectively studied a series of 25 patients scheduled for treatment. MATERIALS AND METHODS: Between January 1994 and June 1995, 15 males and 10 females with a mean age of 44 years (median 43; range 4 to 70 years) underwent ESWL of calyceal stones <5 mm using an unmodified HM3 Dornier lithotriptor. RESULTS: Indications for ESWL included 17 patients (68%) suffering from back and flank pain, 3 patients (12%) with gross hematuria and 1 patient (4%) with recurrent episodes of pyelonephritis. Six patients (24%) were asymptomatic. Evaluation 3 months after ESWL revealed that of the 17 patients with flank pain, 13 (76%) had complete resolution of pain and 4 (24%) had partial resolution of pain and there had been no further episodes of gross hematuria or pyelonephritis in the previously affected patients. At 3-month follow-up, of the 31 kidneys treated, plain radiography were available in 29; 20 (69%) were clear and 9 (31%) had small residual fragments. CONCLUSIONS: Calyceal stones <5 mm in maximum diameter can cause significant symptoms such as pain, hematuria and infection and should not be dismissed as inconsequential. When no other obvious cause is apparent, these small stones should be treated with a high likelihood of resolution of symptoms and clearance. ESWL should not be withheld in patients with small asymptomatic calculi who request or require treatment for fear of unexpected colic or stone growth.

A 57-year-old woman, known to have diabetes mellitus, presented with a one-week history of fever, dysuria, and left flank pain. Computed tomography showed extensive left renal parenchymal destruction and a large gas collection. Urine culture revealed growth of Escherichia coli. The diagnosis of emphysematous pyelonephritis was confirmed at left nephrectomy. The clinical manifestations of emphysematous pyelonephritis, types of gas-forming renal infection, and their radiological findings are discussed.

Xanthogranulomatous pyelonephritis and staghorn calculus are rare in children. In this report, we describe a Chinese boy without history of urinary tract infection who developed insidious onset of left flank pain. Urine culture showed Proteus mirabilis infection. Sonography and computed tomography of the abdomen showed typical picture of xanthogranulomatous pyelonephritis and staghorn calculus. Photomicrography showed characteristic lipid-laden macrophage aggregates. After nephrectomy, he was symptom-free. In conclusion, xanthogranulomatous pyelonephritis should be considered in afebrile children with flank pain and staghorn calculus.

Several conditions can clinically mimic renal colic. We assessed the accuracy of non-contrast-enhanced helical CT and of ultrasonography (US) in offering an alternative explanation for flank pain. In a 3-year period, 181 patients with acute flank pain underwent US and non-contrast-enhanced helical CT in a blinded sequence. Their efficacy in detecting both alternative causes of pain and additional findings unrelated to the pain was assessed in 160 cases with a confirmed diagnosis. An alternative cause was found in 23 cases (14%). US gave 4 false-negative results (1 acute appendicitis, 1 ovarian cyst torsion, 1 diverticulitis, and 1 papillary necrosis) and 2 false-positive results (1 acute pyelonephritis and 1 diverticulitis), with a 78% sensitivity and a 98% specificity for nonlithiasic causes. CT gave 5 false-negative results (1 complicated ovarian cyst, 1 pleuritis, 1 epididymitis, 1 acute pyelonephritis, and 1 papillary necrosis) and 1 false-positive (1 simple ovarian cyst described as a complicated lesion), resulting in a 74% sensitivity and a 99% specificity for diagnosing alternative causes. There were 130 additional US findings in 68 patients and 151 additional CT findings in 77 patients. A wide spectrum of findings can be identified in subjects imaged for flank pain. Non-contrast-enhanced helical CT and US have comparable accuracy in diagnosing causes other than stone disease.

During the past decade, unenhanced computed tomography (CT) has become the standard of reference in the detection of urinary calculi owing to its high sensitivity (>95%) and specificity (>98%) in this setting. Numerous diseases may manifest as acute flank pain and mimic urolithiasis. Up to one-third of unenhanced CT examinations performed because of flank pain may reveal unsuspected findings unrelated to stone disease, many of which can help explain the patient's condition. Alternative diagnoses are most commonly related to gynecologic conditions (especially adnexal masses) and nonstone genitourinary disease (eg, pyelonephritis, renal neoplasm), closely followed by gastrointestinal disease (especially appendicitis and diverticulitis). Hepatobiliary, vascular, and musculoskeletal conditions may also be encountered. Vascular causes of acute flank pain must always be considered, since these constitute life-threatening emergencies that may require the intravenous administration of contrast material for diagnosis. Radiologists must be familiar with the typical findings of urinary stone disease at unenhanced CT, as well as the spectrum of alternative diagnoses that may be detected with this modality, to accurately diagnose the source of flank pain.

Although the kidney is often involved in disseminated and localized candidiasis, bilateral emphysematous pyelonephritis (EPN) is infrequently reported. Renal papillary necrosis (RPN) caused by fungi is also rare. We describe a patient with bilateral RPN and EPN caused by Candida tropicalis, who suffered from recurrent hematuria, flank pain, acute fulminant renal failure, and obstruction by a sloughed papilla. He was treated successfully with antifungal therapy and percutaneous nephrostomy (PCN). This is the first case report of C. tropicalis-associated EPN and RPN.

Acute pancreatitis is not an uncommon disease in an emergency department (ED). It manifests as upper abdominal pain, sometimes with radiation of pain to the back and flank region. Isolated left flank pain being the sole manifestation of acute pancreatitis is very rare and not previously identified in the literature. In this report, we present a case of acute pancreatitis presenting solely with left flank pain. Having negative findings on an ultrasound initially, she was misdiagnosed as having possible "acute pyelonephritis or other renal diseases". A second radiographic evaluation with computed tomography showed pancreatitis in the tail with abnormal fluid collected extending to the left peri-renal space. We performed a literature review and discussed this rare occurrence of acute pancreatitis. We also discussed the clinical pitfalls in this case.

Xanthogranulomatous pyelonephritis is a rare condition in children. A 7-year-old boy developed right flank pain and tenderness 1 month after an appendectomy. Abdominal computed tomography scan documented a right renal mass. A right nephrectomy was performed. The pathological report documents xanthogranulomatous pyelonephritis. He experienced an uneventful recovery. Xanthogranulomatous pyelonephritis should be included in the differential diagnosis of children with fever, weight loss, flank tenderness, and a renal mass.

Acute focal bacterial nephritis or acute lobar nephronia is an acute localized non-liquefactive bacterial kidney infection. Clinically, it may develop as an abscess and present as acute pyelonephritis but is distinguishable by the presence of a focal mass on imaging studies. The authors report the case of an 8-year-old girl with fever up to 39 degrees C and left flank pain of 6 days duration. On physical examination, she had nothing remarkable except tenderness and knocking pain over the left costovertebral angle. Post-contrast abdominal computed tomography revealed several wedge-shaped hypodense lesions in the left kidney. Urine culture grew Escherichia coli. Acute focal bacterial nephritis was diagnosed. The patient was treated with antibiotics and discharged on the 12th day of hospitalization.
