We present a case of a patient with xanthogranulomatous pyelonephritis (XGP) presenting with a large (18 × 12 cm) left-sided flank mass with worsening left flank pain. CT abdomen/pelvis demonstrated a left kidney with parenchyma replaced by multiple large hypodense collections containing fluid and gas, a left staghorn calculus, and a communication between the kidney and large flank collection. ...

Urinary tract infections (UTI) are common in adults and are known to cause deterioration in renal function in patients with chronic renal impairment, solitary kidneys and renal transplants. Acute non-obstructive pyelonephritis is rarely considered in the differential diagnosis of acute renal failure (ARF), especially in patients with little or no evidence of previous kidney disease. Diagnosis i...

Aim: To evaluate our experience with emphysematous pyelonephritis in a tertiary care facility and to describe approach. Study design: Cross-sectional retrospective study Place duration of study: Dept Urology, Shaikh Zayed Hospital, Lahore from 1st January 2017 31st December 2020. Methodology: Thirty six patients who died out the 976 between 34-82 years were enrolled. Used classification systems...

Although coliform bacteria are the organisms most commonly recovered from the urine of patients with pyelonephritis, they seldom cause infection in the absence of some kind of renal injury.' These bacteria are not suitable, therefore, for experiments designed to study alterations of structure and function attributable to infection alone. For these purposes it would seem preferable to employ mic...

Introduction. Pyelonephritis is a common complication of pregnancy. It is also exacerbated by immunocompromised states and also the sickle cell gene. We reviewed this condition in Jamaican women. Method. We did a six year hospital database docket review. We found 102 confirmed cases. Results. Pyelonephritis was found in 0.7% of deliveries. The mean maternal age was 24 ± 5.83 years with 51% prim...

Emphysematous pyelonephritis is a gas-producing, necrotizing infection involving the renal parenchyma and surrounding tissue that is associated with high mortality and morbidity. Common causative organisms include Escherichia coli and Klebsiella pneumoniae. While most patients are being managed conservatively these days, nephrectomy may be needed in severe cases.

Emphysematous pyelonephritis (EPN) is a severe necrotizing infection of the renal parenchyma. The clinical course of EPN can be severe and life-threatening if not recognized and treated promptly. Most of the information has been from case reports, a few large series have also been reported. Using an evidence-based approach, this review describes the pathogenesis, classification, complications, ...

The initial management of pyelonephritis needs to look for complicating factors. Ultrasound and X ray of the abdomen are able to rule out a urinary dilatation or a stone. The treatment is then surgical with renal drainage. Additional investigations such as a CT scan should be performed in patients with complicating factors or recurrence. In uncomplicated pyelonephritis a ambulatory treatment wi...

The pattern of ampicillin resistance and possible association with virulence factors of 78 Escherichia coli isolates taken from 78 pregnant women with pyelonephritis were evaluated. The current incidence of ampicillin resistance among pyelonephritis isolates (46%) was significantly higher than that reported in 1985 (22%). Resistance was found more frequently during the first (60%) and third (53...

Rats with desoxycorticosterone (DCA) -saline induced hypertension have been shown to exhibit increased susceptibility to experimental pyelonephritis (1, 2). These studies lend support to the hypothesis that various injuries, including nephrosclerosis, predispose to human pyelonephritis and that pyelonephritis is superimposed upon hypertensive disease more frequently than is usually suspected. O...
