A man with a solitary bladder carcinoma suffered acute tubular necrosis following hydrostatic pressure therapy. The nephrotoxicity caused by antibiotics and/or the septicemic shock seems to be responsible. The animal experiment suggested changes in the technique: 1) the bladder should be overdistended via a Foley catheter with a rubber ballon at the tip to prevent a possible postoperative complication and 2) one should try to decrease rather than maintain the high intravesical pressure during overdistension to avoid bladder wall rupture. The overstretching of a blood vessel alone is quite sufficient to bring the anoxia upon the bladder tumor, which is verfied by the biophysical principle.

Bilateral internal iliac artery infusion of chemotherapeutic agents in patients with advanced bladder carcinoma, Stage D, resulted in a 50% response or greater in nine of 15 patients with a median survival, thus far, of 52 weeks. Hematuria was controlled in eight of ten patients, and pain was relieved in 12 of 15 patients. Three additional patients were treated as adjuvants after their residual tumor was removed surgically or irradiated before chemotherapy. Cis-diamminedichloroplatinum (CDDP) was infused at a dose of 80--120 mg/m2 over a 24-hour period. When CDDP failed or in the presence of impaired renal function, a combination of 5-fluorouracil (5-FU) infused intraarterially while Adriamycin and mitomycin C were delivered intravenously, salvaged two patients. Complications were tolerable, consisting of transient acute tubular necrosis in two patients, a lower extremity embolus in one, and skin reactions due to 5-FU in two patients.

Renal failure secondary to CDDP is due to acute tubular necrosis and is usually reversible. We report 4 cases of definitive renal failure secondary to administration of cisplatin (CDDP). Three women and one man, mean age 40 +/- 8 years (24 to 64 years), at onset of dialysis are reported. They had received 1 to 4 courses of CDDP for an endometrial carcinoma (n = 2), a breast carcinoma or a thymoma. The mean total dose of CDDP was 447 +/- 169 mg (160 to 900 mg). There was no additional nephrotoxic drug. Before treatment serum creatinine concentration was normal (77 +/- 7 mumol per liter) in all patients. In 2 cases dehydration (due to vomiting and use of mannitol) occurred during CDDP treatment. One patient was treated 30 days after a nephrectomy. At the onset of dialysis, renal ultrasound was normal. In 3 cases dialysis was necessary within 15 days following chemotherapy. In one case renal function deteriorated progressively to end stage renal failure 12 months after CDDP treatment. Dialysis was performed in 3 cases by hemodialysis and in one patient by peritoneal dialysis. All patients remained more than 6 months on dialysis. Three patients died from their cancer. One patient, being considered cured from his thymoma, is currently being evaluated for a kidney transplantation. Our observations outline the potential severity of CDDP nephrotoxicity. Systemic hydration with serial serum creatinine measurements are mandatory during and after CDDP administration these patients.

We describe 2 patients with minimal-change glomerulopathy (MCG) associated with an undifferentiated carcinoma of unknown origin and urothelial carcinoma. Oliguric acute renal failure and histopathological changes consistent with acute tubular necrosis were also observed. Fourteen other cases of MCG complicating solid tumors reported in the literature are reviewed. MCG should be included in the nephropathies which cause nephrotic syndrome in adult patients with carcinoma.

The records of 33 patients with perforated left colon lesions over a 6-year period from 1992 to 1998 were examined retrospectively for clinical course and complications. All patients had a free perforation, feculent or purulent peritonitis, and/or a large inflammatory mass. All patients had primary resection and anastomosis without a protective colostomy or ileostomy. Indications included diverticulitis in 28 patients, obstructing colorectal carcinoma in 3, and iatrogenic perforations in 2. Complications occurred in 10 patients, including atelectasis in 1, urinary retention in 2, urinary tract infections in 2, wound infections in 3, line catheter sepsis in 1, and acute tubular necrosis in 1. There was one anastomotic dehiscence, which was successfully converted to a Hartmann procedure. Patients were discharged an average of 7 days after surgery. Two patients required surgery after discharge: one had a fascial dehiscence and the other an incisional ventral hernia. There was no mortality. Primary resection and anastomosis of selected perforated left colon lesions can be performed with a morbidity and mortality rate lower than that usually reported for the Hartmann procedure.

In the developing world, up to 80% of the population uses traditional medicine for primary health care. In industrialized countries, adaptations of traditional medicine, termed "complementary" or "alternative" medicine (CAM), are used by a growing number of patients for preventive or palliative care. However, alternative medicine (AM) may be an important risk for the development of acute and chronic kidney injury because of several factors: nonconventional preparations rarely meet the required essential standards of consistency in composition and biological activity; many of these products contain undisclosed over-the-counter or prescription drugs or can be adulterated with hormones and glandular extracts; herbal preparations can be contaminated by pesticides and heavy metals; and because of errors in plant identification and confusing terminology, opportunities for mistakes and deliberate substitution can occur. Furthermore, there is a lack of reports of adverse events and drug interactions because of a lack of professional surveillance, and specific data on systemic and kidney toxicity are not easily available. Kidney injury/kidney syndromes caused by AM consist of acute tubular necrosis/toxicity (eg, Fanconi's syndrome), acute interstitial nephritis, papillary necrosis, hypertension, kidney stones, urinary retention, chronic tubulointerstitial nephritis with fibrosis, urinary tract carcinoma, and acute rejection of the kidney transplant. To improve the care for patients using AM, extension of physicians' knowledge about its possible hazards and toxicity is essential. This review deals with acute and chronic kidney toxicity caused by animal-, plant-, and mineral-based, nonconventional medicine and kidney failure caused by drug interactions with AM.

Renal failure secondary to carboplatin therapy is due to acute tubular necrosis and is usually reversible. However, acute renal failure with rapid progression to end-stage renal disease is an exceedingly rare complication of carboplatin therapy. The authors report a case of definitive renal failure secondary to carboplatin chemotherapy for a nasopharyngeal carcinoma. The mechanisms that give rise to the chronic nephropathy are discussed.

Numerous anatomical and functional changes occurring in the aging kidney lead to reduced glomerular filtration rate, lower renal blood flow and impaired renal autoregulation. The elderly are especially vulnerable to the development of renal dysfunction and in this population acute renal failure (ARF) is a common problem. ARF is often iatrogenic and multifactorial; common iatrogenic combinations include pre-existing renal dysfunction and exposure to nephrotoxins such as radiocontrast agents or aminoglycosides, use of NSAIDs in patients with congestive cardiac failure and use of ACE inhibitors and diuretics in patients with underlying atherosclerotic renal artery stenosis. The aetiology of ARF is classically grouped into three categories: prerenal, intrinsic and postrenal. Prerenal ARF is the second most common cause of ARF in the elderly, accounting for nearly one-third of all hospitalized cases. Common causes can be grouped into true volume depletion (e.g. decreased fluid intake), decreased effective blood volume (e.g. systemic vasodilation) and haemodynamic (e.g. renal artery stenosis, NSAID use). Acute tubular necrosis (ATN) is the most common cause of intrinsic ARF and is responsible for over 50% of ARF in hospitalized patients, and up to 76% of cases in patients in intensive care units. ATN usually occurs after an acute ischaemic or toxic event. The pathogenesis of ATN involves an interplay of processes that include endothelial injury, microvascular flow disruption, tubular hypoxia, dysfunction and apoptosis, tubular obstruction and trans-tubular back-leak. Vasculitis causing ARF should not be missed as this condition is potentially life threatening. The likelihood of a postrenal cause for ARF increases with age. Benign prostatic hypertrophy, prostatic carcinoma and pelvic malignancies are all important causes. Early identification of ARF secondary to obstruction with renal imaging is essential, and complete or partial renal recovery usually ensues following relief of the obstruction.A comprehensive medical and drug history and physical examination are all invaluable. Particular attention should be paid to the fluid status of the patient (skin turgor, jugular venous pressure, lying and standing blood pressure, urine output). Urinalysis should be performed to detect evidence of proteinuria and haematuria, which will aid diagnosis. Fractional excretion of sodium and urine osmolality may be measured but the widespread use of diuretics in the elderly gives rise to unreliable results. Renal imaging, usually ultrasound scanning, is routinely performed for assessment of renal size and to exclude urinary obstruction. In some cases, renal biopsy is necessary to provide specific diagnostic information. The general principles of managing ARF include treatment of life-threatening features such as shock, respiratory failure, hyperkalaemia, pulmonary oedema, metabolic acidosis and sepsis; stopping and avoiding administration of nephrotoxins; optimization of haemodynamic and fluid status; adjustment of drug dosage appropriate to glomerular filtration rate; early nutritional support; and early referral to nephrologists for diagnosis of ARF cause, timely initiation of dialysis and initiation of specific treatment. The treatment of prerenal and ATN ARF is largely supportive with little evidence of benefit from current pharmacological therapies. Despite advances in critical care medicine and renal replacement therapy, the mortality of ARF has not changed significantly over the last 40 years, with current mortality rates being up to 75%.

Oxaliplatin is an effective chemotherapeutic agent frequently used in the treatment of colorectal carcinoma. Rare cases of renal failure and hemolytic reactions have been reported as separate side effects of oxaliplatin. Here we present a clinical picture of immune-related intravascular hemolysis and acute tubular necrosis in a patient receiving this drug. This case suggests a mechanistic explanation of renal failure in patients treated with oxaliplatin.

We report a patient with unknown primary undifferentiated carcinoma who developed acute renal failure associated with interstitial fibrosis following pemetrexed therapy. Despite drug withdrawal, renal function remained altered and the patient experienced chronic renal insufficiency. Pemetrexed disodium (Alimta) is a multitargeted antifolate agent approved by the Food and Drug Administration (FDA) for patients diagnosed with mesothelioma and non-small cell lung cancer. This drug is almost exclusively cleared by renal excretion [1]. The most common side effects are hematologic dose-limiting toxicities and nonhematologic toxicities including fatigue, diarrhea, nausea, mucositis and rash. Although few cases of renal failure have been published, no study has reported on the renal pathological findings in this setting. We present a case of acute tubular necrosis associated with interstitial fibrosis after pemetrexed therapy.
