Pyonephrosis is an uncommon disease that is associated with suppurative destruction of the renal parenchyma in adults. Upper urinary tract infection and obstruction play a role in its etiology. Immunosuppression from medications (steroids), diseases (diabetes mellitus, AIDS), and anatomic variations (pelvic kidney, horseshoe kidney) may also be risk factors for pyonephrosis. Fever, shivering, and flank pain are frequent clinical symptoms. On physical examination, a palpable abdominal mass may be associated with the hydronephrotic kidney. Septic shock and death can occur if the disorder is not treated with urgent surgery. After the acute phase, most patients are treated with nephrectomy. In this paper, we share the etiology, clinical features, diagnosis and treatment of pyonephrosis using the background of a case with giant pyonephrosis developing due to a kidney stone, the most common cause of upper urinary tract obstruction.

Extramedullary plasmacytoma (EMP) is a rare malignant tumor that is characterized by a malignant plasma cell neoplasm. Such neoplasms in human immunodeficiency virus (HIV)-infected patients are extremely rare. To the best of our knowledge, the present study describes the first case of a solitary adrenal EMP in a patient with HIV. A 35-year-old male who had been diagnosed with HIV 3 months previously presented with a 2-week history of intermittent right flank pain. Abdominal computed tomography revealed a soft-tissue density mass in the right adrenal gland area. The patient subsequently underwent a retroperitoneal laparoscopic adrenalectomy. Post-operative pathological diagnosis revealed a solitary EMP. Although the patient refused to undergo post-operative radiotherapy and chemotherapy, no recurrence was detected after 2 years of follow-up. The present case illustrates the fact that this rare type of solitary EMP associated with acquired immune deficiency syndrome (AIDS) can occur in the adrenal glands, and that retroperitoneal laparoscopic resection of the tumor may be a good method to manage this condition. In addition, although rare, solitary EMP should be considered in the differential diagnosis of an adrenal mass in HIV-infected patients.

Biliary and urinary obstructions can be managed endoscopically or cystoscopically, surgically or by percutansous intervention or drainage. If the obtructed system is infected, emergent decompression is needed. Early recognition and treatment is paramount in both conditions. Acute cholangitis can present many different ways, from mild symptoms to fulminant sepsis. It is usually a result of ascending bacterial colonization and biliary obstruction resulting in bacterial overgrowth. Therefore, those patients with recent biliary instrumentation or previous biliary modification are at higher risk. Charcot's triad of fever, right upper quadrant abdominal pain, and jaundice is only seen in 50%-70% of patients. Fever is seen in over 90% of cases, pain is seen in 70% of cases, and jaundice is seen in 60% of cases. Altered mental status and hypotension are associated with severe cases. All 5 symptoms of fever, right upper quadrant abdominal pain, jaundice, altered mental status, and hypotension are referred to as Reynold's Pentad. Acute pyonephrosis can also present many different ways, from minimal symptoms to fulminant sepsis. Fever, chills, and flank pain are the classic symptoms, although some patients may be relatively asymptomatic. Pyonephrosis may present with a classic triad of fever, flank pain, and hydronephrosis, or simply hydronephrosis and sepsis. Pyonephrosis usually occurs as a result of urinary obstruction with either an ascending infection of the urinary tract or hematogenous spread of a bacterial pathogen as the culprit. Up to 75% of cases are related to urinary stone disease. Patients are at increased risk for pyonephrosis when they haven anatomic urinary tract obstruction, certain chronic diseases (diabetes meliitus and AIDS), or are immunosuppressed due to immunodeficiency or medications, (chronic steroid therapy).
