Chronic bacterial prostatitis is generally difficult to treat. It may involve multiple courses of antibiotics and may be difficult to eradicate with high rates of recurrence. We present the case of a 33-year-old male patient with a previous history of renal tract calculi, stent insertions, and perinephric abscess with percutaneous drainage, which then led to a right nephrectomy.

Iliopsoas Abscess Mimicking a Lower Motor Neuron Lesion: A Diagnostic Challenge.

Cureus

November 2024

Internal Medicine, Mid and South Essex NHS Foundation Trust, Southend-on-Sea, GBR.

Iliopsoas abscess is a rare infection that presents with a triad of fever, back pain, and hip pain. However, due to the anatomical proximity of the psoas muscle to various structures, an abscess in this region can manifest with nonspecific symptoms, leading to potential misdiagnosis and delayed diagnosis, which can be fatal. We report a case of a 54-year-old female who presented to the emergency department with right-sided flank pain and symptoms resembling lower motor neuron disorder.

is an opportunistic bacterium that is often identified in asymptomatic, healthy individuals from colonization of the genitourinary tract. However, in immunocompromised patients with hypogammaglobulinemia, has been reported to cause a wide range of infections, most commonly urethritis and cystitis. The absence of a bacterial cell wall prevents from being cultured using routine bacteriologic media and makes it resistant to commonly prescribed antibiotics.

Urologic trauma encompassed a wide range of injuries affecting the urologic tract, resulting from various traumatic events or iatrogenic procedures. This review explores the clinical presentation, diagnostic strategies, and management approaches of urologic trauma, emphasizing the critical role of imaging, particularly computed tomography, in accurately assessing and guiding treatment decisions. Renal, ureteral, bladder, and urethral trauma are comprehensively discussed, including mechanisms of injury, classification systems, and therapeutic interventions.

Empyema complicated with nephropleural fistula and perinephric abscess.

BMJ Case Rep

October 2024

Division of Pulmonology and Critical Care, Unity Hospital, Rochester Regional Health, Rochester, New York, USA.

Article Synopsis
  • The case report discusses a rare medical situation involving empyema, nephropleural fistula, and perinephric abscess in a 90-year-old female patient presenting with chest pain and a left-sided pleural effusion.
  • Imaging revealed not only the pleural effusion but also a nephropleural fistula and perinephric collection.
  • The patient underwent thoracic surgery, had her kidney removed due to chronic infection, and showed improvement after treatment, ultimately resolving her symptoms two weeks post-discharge.

Calyceal rupture, defined as the extravasation of urine from the renal calyces into the perinephric or paranephric spaces, typically results from increased intrapelvic pressure due to urinary tract obstruction. This condition can lead to the formation of a perinephric urinoma and severe complications, such as infection, abscess formation, and impaired renal function. Timely diagnosis and management are crucial to prevent these adverse outcomes.

Renal and Urinary Conditions: Urinary Tract Infections.

FP Essent

August 2024

Family Medicine Hospitalist Fellowship Program, Womack Army Medical Center.

Urinary tract infections (UTIs), including cystitis and pyelonephritis, are common. Each year, they account for more than 10 million outpatient visits and more than 3 million emergency department visits. Recurrent UTIs (defined as three in 1 year or two in 6 months) also are common, occurring in 20% to 30% of women.

The incidence of bacterial infections is high in patients with liver cirrhosis (LC) due to compromised immune systems. They are associated with acute hepatic decompensation, multiorgan dysfunction, high morbidity, and mortality and account for 25-46% of all hospitalizations. The mortality rate is about 30% after one month and increases to 63% at one-year follow-up.

Introduction And Importance: Renal trauma is a common and associated complication of abdominal trauma. Although there is consensus that most high-grade injuries require surgical exploration, nonoperative management remains a viable approach. We aim to report case reports of four cases of nonoperative isolated high-grade blunt renal trauma in adults, followed by a literature review.

Background: Emphysematous pyelonephritis (EPN) is a rare acute severe necrotising infection of the kidneys in clinical practice. It is characterized by the presence of gas in the renal parenchyma, collecting system, or perirenal tissue. The prognosis is poor, with a high nephrectomy rate and a mortality rate of up to 20-40%.

Nephropleural fistula, a rare complication of percutaneous nephrolithotomy (PCNL), occurred in a 45-year-old male with adult autosomal dominant polycystic kidney disease (ADPKD). The patient had undergone right PCNL in 2021 and 2023 and presented to the emergency department with symptoms of fever, breathlessness, and cough lasting one week. Imaging studies, including chest radiograph and contrast-enhanced computed tomography (CECT) of the abdomen and pelvis, revealed gross right pleural effusion, right perinephric abscess, multiple renal cysts, right renal calculi and right ureteric calculi causing severe right hydronephrosis and proximal hydroureter.

Introduction: Nontraumatic biliary rupture and retroperitoneal biloma infrequently occur. Here, we report a case of retroperitoneal biloma due to spontaneous left hepatic duct perforation, which was difficult to differentiate from a perirenal abscess.

Case Presentation: A 94-year-old female patient was hospitalized with symptoms of fatigue and right back pain that lasted for 5 days.

Retroperitoneal abscess as a sequela of penetrating trauma can pose a difficult clinical scenario for surgeons and literature to inform decision making is sparse. It is logical to follow a "step-up" approach applied to other etiologies of infected retroperitoneal fluid collections, such as infected pancreatic necrosis and perinephric abscess. Video-assisted retroperitoneal debridement (VARD) is a well-established approach in infected pancreatic necrosis when surgical debridement is warranted.

Key Clinical Message: Filariasis may present as an isolated perinephric abscess. Hence, a high index of suspicion should be maintained in endemic settings.

Abstract: In cases with unexplained fever, eosinophilia and perinephric collection, it is necessary to do detailed infectious disease work up.

Renal and perinephric abscesses are rare purulent infections within or around renal parenchyma, typically treated with antibiotics or various procedural approaches depending on abscess size. In this case report, we describe the novel use of a transgastric endoscopic ultrasound (EUS)-guided technique with placement of a stent for drainage between a renal abscess and the stomach in a patient who had failed attempted percutaneous drainage twice and where an open surgical approach was deemed inappropriate. The patient presented with a chief complaint of left flank pain, with CT revealing a ~4 x 4 cm renal abscess in the upper pole of the left kidney.

Article Synopsis
  • - The study evaluated the safety and effectiveness of percutaneous cryoablation (PCA) in 94 patients with central renal tumors and found that 94% of the procedures achieved primary technical success.
  • - Out of the patients, 6% experienced major adverse events, but the overall survival rate was high at 94%, and cancer-specific survival reached 98%.
  • - The results suggest that PCA can be safely performed on central renal tumors without pyeloperfusion, indicating it could be a viable treatment option.

Emphysematous pyelonephritis (EPN) is a suppurative necrotizing form of renal infection with abscess and gas formation in the renal parenchyma and perirenal tissue. EPN with scrotal extension is rare; if not recognized and treated promptly, the clinical course can be severe and life-threatening. The most common causative organism is and association with diabetes mellitus has been found in almost all cases.

Unlabelled: Emphysematous pyelonephritis (EPN) is a rare and life-threatening sequalae of a urinary tract infection marked by a gas-producing necrotizing infection of the renal parenchyma requiring prompt treatment. It has been found to be correlated with uncontrolled diabetes mellitus and is more common in females due to their increased susceptibility to urinary tract infections. Early recognition and treatment of EPN are essential to improve the patient's prognosis and prevent further complications.
