A series of 70 pyonephrotic kidneys drained by percutaneous nephrostomy tube was examined to evaluate the contribution of radiologic imaging to the diagnosis of pyonephrosis and to assess the diagnostic and therapeutic role of drainage by percutaneous nephrostomy catheter. The diagnosis of pyonephrosis is suspected when the clinical symptoms of fever and flank pain are combined with the radiologic evidence of obstruction to the urinary tract. Sonography gives a prompt diagnosis of hydronephrosis, and needle puncture of the kidney yields pus and establishes the presence of pyonephrosis. A percutaneous nephrostomy catheter is then inserted and serves for initial drainage of infected urine and for evaluation of residual kidney function before definitive surgery. The nephrostomy catheter is used for diagnostic nephrostograms, ureteral perfusions, therapeutic dissolution of stones, and indefinite drainage of the kidney. In 10 azotemic patients, the blood urea nitrogen and serum creatinine values returned to normal levels after antibiotic therapy and nephrostomy drainage of infection. Long-term evaluation of residual renal function by means of an excretory urogram or a renogram was available in another 26 patients and 25 of them showed function of the previously pyonephrotic kidney.

While calcium oxalate and calcium phosphate make up at least 80% of all kidney stones, infection-induced and uric acid stones occur in 10% and 8%, respectively. Although any type of stone may become infected, the term "infection stones" means that stone formation exclusively depends on urease-producing bacteria. The splitting of urea leads to a rise in urinary pH which may induce crystallization of struvite (magnesium-ammonium-phosphate), the major constituent of infection stones, or carbonate apatite. Struvite stones account for the majority of staghorn calculi. They can grow quite large and may fill the entire collecting system. Patients with struvite stones may present with acute flank pain or remain completely asymptomatic. The cure of infection stones requires complete removal of the stone material. For uric acid crystallization and stone formation, low urine pH (below 5.5) is a more important risk factor than increased urinary uric acid excretion. Main causes of low urine pH are tubular disorders (including gout), chronic diarrheal states or severe dehydration. Accordingly, the treatment of uric acid stones consists not only of hydration (urine volume above 2000 ml per day), but mainly of urine alkalinization to pH values between 6.2 and 6.8. Urinary uric acid excretion can be reduced by a low-purine diet as well as--in case of recurrent uric acid stones and/or gout--by allopurinol. Cystinuria is a rare hereditary gene disorders with impaired tubular reabsorption of cystine. Stone formation occurs as a consequence of cystine's relatively low solubility at urine pH levels below 8. Only symptomatic diet and drug treatments are currently available, with urine dilution and urine alkalinization being the most efficient ones. Cystine stones respond poorly to shockwave lithotripsy, so that invasive procedures may regularly be necessary. 2,8-dihydroxy-adenine stones occur as a consequence of an enzyme deficiency that involves purine metabolism. These resulting stones are not visible by fluoroscopy and are therefore often misinterpreted as uric acid stones. Low-purine diet and allopurinol reduce the frequency of stone formation.

Acute renal failure (ARF) occasionally occurs after intravenous injection of contrast medium, but complications are rare after retrograde pyelography. After reviewing the reports in the English-language literature, the authors found very few on those complications after retrograde pyelography. The authors present a patient who had ARF after the technique. The patient had a history of hypopharyngeal cancer with underlying serum creatinine level at the high end of the normal limits. Bilateral flank pain and decreased urine amount were noted soon after the procedure of retrograde pyelography. Subsequently, blood urea nitrogen and creatinine levels both elevated, and hemodialysis was needed. Several days later, diuretic phase took place. Thereafter, the symptoms subsided gradually. Pyelorenal extravasation of contrast medium was remarkable during the procedure. There was no evidence of hydronephrosis during the course of ARF. Early awareness and management may prevent the complications of ARF such as acute lung edema and hyperkalemia. Therefore, clinical physicians should be aware of the occurrence of ARF and its clinical presentation after performing retrograde pyelography.

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.

A 56-year-old woman with obesity and poorly controlled diabetes mellitus presented with a two-day history of abdominal fullness and vomiting. No fever, flank pain or dysuria was present. On admission, her blood urea nitrogen concentration was 74 mg per deciliter and the serum creatinine concentration was 3.5 mg per deciliter. Laboratory data revealed an elevated white blood cell count (11.72 x 10(3)/ml), blood sugar (826 mg/dl), pyuria (WBC 30-50/HPF) and negative urine ketone. A plain abdominal radiograph revealed right renal stones and localized air accumulation at the left upper abdominal area.

Emphysematous or gas-forming infections, a very small percentage of bacterial infections of the urinary tract, attract importance because of their life threatening potential. Herein, we report a 60-year-old Saudi female patient who was a known case of Diabetes mellitus for 15 years. She was admitted with left flank pain of 5 days duration, abdominal distension, nausea, vomiting and chills associated with increased frequency of urine, urgency, and dysuria. She had leukocytosis, high blood sugar, elevated urea and creatinine and pyuria. Urine culture grew Escherichia coli. Ultrasound and CT scan showed left pelvicalyceal dilatation and air in the left kidney and urinary bladder. She was treated with a prolonged parenteral antibiotic course, and insulin, with complete recovery.

An undifferentiated renal tubular carcinoma was diagnosed in a juvenile male olive baboon (Papio anubis). The animal suddenly appeared depressed and refused to eat. During physical examination, a firm, palpable mass in the left abdominal area and flank pain were detected. Clinical pathology findings included mild anemia, hypoalbuminemia, hyponatremia, and mildly increased serum creatinine and urea concentrations. Radiographs revealed a large mass in the left abdominal area. Exploratory laparotomy disclosed a 10 cmx15 cm multilobulated mass involving the left kidney and adjacent organs. Because of a poor prognosis, the animal was humanely euthanized, and necropsy was performed. Tissue samples of the neoplasm were taken for histopathological examination. Immunohistochemical staining was done using vimentin, cytokeratin, S-100 protein, Ki-67, alpha-actin, and desmin-specific primary antibodies. Microscopically, elongated and irregular tubules were lined by 2 or more layers of atypical epithelial cells. Anisocytosis, anisokaryosis, and frequent mitotic figures were also observed. Following immunohistochemical staining, the cytoplasm of neoplastic cells was positive for cytokeratin, vimentin, and S-100 protein and negative for alpha-actin and desmin. Positive nuclear staining for Ki-67 was observed. The neoplasm was diagnosed as an undifferentiated renal tubular carcinoma.

A 65-year-old man with a history of Castleman's disease presented with abdominal and right flank pain. He denied any recent trauma. On admission, his hemoglobin was 7.0 g/dL, and the blood urea nitrogen and serum creatinine concentration was 30 and 1.62 mg/dL, respectively. Computed tomography of the patient's abdomen revealed a large right perinephric hematoma. The patient underwent emergency nephrectomy. Microscopic examination of the specimen revealed an incidental renal cell carcinoma.
