A total of 481 cases of retroperitoneal fibrosis (RPF) presented in the literature have been reviewed. Ten additional cases from this hospital have been added. One etiological factor, methysergide, has been implicated in 12.4 percent of cases, but the majority remain unexplained. Characteristically, the patient will be male (2:1 ratio), in his 50's (30.9 percent), with vague lower back pain (34.2 percent) or possibly flank pain (34.0 percent). Physical examination usually will be unrevealing. The patient's serum chemistry probably will show some degree of azotemia (55.4 percent) and perhaps anemia (13.6 percent). The intravenous pyelogram characteristically shows bilateral hydroureteronephrosis (67.6 percent) or unilateral hydroureteronephrosis (20.3 percent) associated with medial deviation of the ureter due apparently to external compression of the ureter. Methysergide should be discontinued if implicated. Laparotomy for ureteral compression characteristically will reveal a dense, rubbery plaque in the retroperitoneum. Generous frozen section biopsies show fibrosis, usually with some chronic inflammation, suggestive of RPF. Careful inspection of retroperitoneal nodes and liver may reveal the presence of malignancy in 7.9 percent of patients. In the absence of malignancy, the ureters should lyse fairly freely and peristasis may return. If no malignancy is present on permanent sections of biopsy material, the patient can be given a fairly optimistic prognosis (cumulative mortality rate, 9 percent). Suboptimal improvement probably is an indication for steroid therapy and surgical re-exploration may become indicated. In these cases further search for malignancy should be undertaken.

Cocaine abuse is associated with a constellation of serious medical complications. An unrecognized and recently described complication of cocaine use is rhabdomyolysis with acute renal failure. We describe the first patient identified in our institution with this entity, admitted to the medical services with oliguric acute renal failure. Three days prior to admission the patient had a cocaine snorting binge. He presented with bilateral flank pain, gross hematuria, vomiting and chills. No history of crush injury, prolonged immobilization and or seizures was reported. On admission the vital signs were normal, physical exam revealed periorbital edema and marked soft tissue neck swelling. Lab values: Bun 120 mgs%, Creat. 10.7 mgs%, Na 132 meq/lt, Co2 13mq/lt, Cl, 103meq/lt, Co2 13meq/lt, Ca 5.3 mgs%, CPK 30,800 U/L with a MM fraction of 98%, LDH 600 U/L, SGOT 300 U/L. The urine was dark red with a ph of 6.5 and 100 rbc/hpf. The anti-GBM antibody and blood cultures were negative. An abdominal sonogram was normal. He received peritoneal dialysis and was discharged on his 14th hospital day with a CPK of 2,800 U/L and decreasing azotemia. Cocaine associated rhabdomyolysis has only been recently described in the literature (AJM April, 88). Acute myoglobinuric renal failure needs to be added to the growing list of medical complications of cocaine use.

A 54-year-old male with the chief complaint of bilateral flank pain was admitted to our hospital. Blood chemistry test revealed marked azotemia and retrograde pyelogram showed bilateral hydronephrosis with median shift of narrowed ureters. Abdominal CT scan demonstrated a well-defined dense mass around the aorta implicating bilateral ureters. These findings were interpreted as aortic perianeurysmal fibrosis resulting in bilateral ureteral obstruction. On laparotomy, a large hard mass was found in the lower part of aorta, vena cava, common iliac vessels, inferior mesenteric artery and bilateral ureters. Because of the extension of the mass, ureterolysis and intraperitoneal displacement of ureters wrapped with isolated omentum was performed. Postoperative recovery from azotemia and ureteral obstruction was satisfactory. Biopsy specimen of the mass showed marked fibrosis with non-specific inflammation.

Two cases of acute renal failure associated with ticrynafen administration are reported. Both patients had received hydrochlorothiazide prior to the institution of ticrynafen therapy and were mildly hyperuricemic. Flank pain, oliguria, and azotemia developed after the institution of ticrynafen in both cases. Clinical and laboratory features were consistent with acute uric acid nephropathy in both patients. In addition, a newly formed collection of radiolucent material was found by intravenous urography in the renal pelvis of one of the patients. Both patients were treated with intravenous fluids and sodium bicarbonate. One of the patients received allopurinol as well. Complete recovery of renal function was observed in both patients. Ticrynafen-induced hyperuricosuria in these previously volume-depleted and hyperuricemic subjects is felt to have been responsible for intrarenal and extrarenal deposition of uric acid in our patients.

The "Septic Kidney" usually originates from infected hydronephrosis. The clinical appearance is characterized by poor general condition, in particular shock, severe flank pain, high fever with chills, leucocytosis and often azotemia. The pathogenesis and definition are discussed on the basis of 110 cases. The various therapeutic modalities such as primary nephrectomy, conservative surgery or endoscopic instrumentation are compared and the indications defined. Conservative procedures are preferred over primary nephrectomy.

High dosages of nephrotoxic drugs in elderly patients might be correlated with an increase in the number of patients with tubulo-interstitial nephritis (TIN). In patients with acute TIN, marked fever, back or flank pain, CVA tenderness, skin rash, arthralgia, eosinophilia, and eosinouria are observed. Clinical symptoms might be induced by glomerular, proximal tubular or distal tubular dysfunction in chronic TIN. Mild to moderate proteinuria, edema, hypertension, azotemia, glucosuria, aminoaciduria, polyuria and polydipsia are characteristic findings in patients with chronic TIN. These findings are slowly progressive in such patients. It appears that the marked fibrosis with lymphocyte infiltration in the interstitium is a poor clinical marker in patients with TIN. Furthermore, it is important to differentiate TIN from glomerulonephritis.

Xanthogranulomatous pyelonephritis is an uncommon variant of chronic pyelonephritis that predominantly affects middle-aged women. Patients usually present with fever, back or flank pain, flank mass, and the constitutional symptoms of fatigue, malaise, weight loss, and anorexia. Rarely, they may present with a draining sinus. There is usually a history of urinary tract infection, obstruction, or instrumentation. Other abnormalities include anemia, leukocytosis, abnormal liver enzymes, pyuria, and hematuria. Mild azotemia may be present, but frank renal failure is rare. Urine and renal tissue cultures are frequently positive. The most commonly isolated bacterial pathogens are P. mirabilis and E. coli, but other organisms have also been implicated. A CT scan is the best radiologic imaging technique to discover the extent of inflammation as well as any involvement of adjacent structures. Lipid-laden macrophages called xanthoma cells characterize the disease at the microscopic level. Nephrectomy is curative. Careful preoperative evaluation will guide surgical planning in choosing an approach that provides adequate exposure of the affected tissue and facilitates subsequent care of the patient.

The syndrome of loin pain hematuria in the absence of stones is poorly understood but must be considered in the differential diagnosis for patients with clinical manifestations resembling nephrolithiasis. A 22-year-old white female with a 4-year history of left flank pain and hematuria underwent an extensive workup with normal renal ultrasound and cystourethroscopies. CT scan and MRI revealed a retro-aortic left renal vein. Posterior nutcracker syndrome was considered the most likely diagnosis. The patient underwent a left laparoscopic nephrectomy with auto-transplantation in the right iliac fossa. She developed azotemia shortly after, which resolved and since then has become asymptomatic.

Background: Zygomycoses are uncommon, frequently fatal diseases caused by fungi of the class Zygomycetes. The majority of human cases are caused by Mucorales (genus-rhizopus, mucor, and absidia) fungi. Renal involvement is uncommon and urine microscopy, pottasium hydroxide mount, and fungal cultures are frequently negative. Case Presentation: A twenty-one-year-old young unmarried lady presented to our emergency department with bilateral flank pain, fever, nausea, and decreased urine output of one-month duration. She was found to have azotemia with sepsis with bilateral hydronephrosis with a left renal pelvic obstructing stone. Even after nephrostomy drainage and broad spectrum antibiotics, her condition worsened. She developed disseminated fungal infection, and timely systemic antifungal followed by bilateral nephroscopic clearance saved the patient. Conclusion: Although renal fungal infections are uncommon, a high index of suspicion and early antifungal and surgical intervention can give favorable outcomes.

Background: Fungal masses (fungal ball or bezoars) rarely present as renal calculus. More so, Trichosporon species are even more uncommon among the noncandidial fungal infections affecting urinary tract. We report two such interesting cases that are not yet reported in the current literature. Case Reports: Our first case is a 48-year-old gentleman with diabetes presented with fever and flank pain. He was found to have bilateral obstructing radiolucent renal calculi with azotemia. Initially managed with bilateral Double-J stenting after one session of hemodialysis, and subsequently bilateral percutaneous nephrolithotomy (PCNL) was accomplished. Our second patient is a 37-year-old lady presented with bilateral flank pain with no comorbidity or sepsis. On evaluation, she was found to have bilateral radiolucent staghorn calculi and for which bilateral PCNL was performed. In view of high suspicion of fungal infection, extracted soft floppy materials were sent for fungal culture and were treated with antifungal agents after Trichosporon species was detected. Conclusion: Although renal fungal infections are rare, a strong suspicion and timely definitive management of such entities in patients with radiolucent renal calculus can prevent devastating invasive disease.
