A low fractional excretion of sodium (FENa) of less than 1% was present in two patients who had acute renal failure due to sepsis. Both patients had bacteremia and had undergone major abdominal and vascular surgery. Prerenal azotemia due to volume depletion was not present as adequate central filling pressures were maintained with a Swan-Ganz catheter. Interstitial nephritis and obstructive uropathy were carefully ruled out. Acute renal failure due to sepsis should be included among the other conditions recently reported with a low FENa. This is of great importance as errors in fluid management are possible in this high-risk patient population when much reliance is placed on the interpretation of a low FENa of less than 1%.

Two infants who had obstructive uropathy accompanied by renal failure and sepsis are reported herein. Diagnostic and therapeutic techniques used to treat this type of surgical emergency are discussed in the order they were performed, as follows: (1) resuscitation for severe fluid and electrolyte disturbances; (2) gathering of cultures and initiation of antibiotic therapy; (3) the decision of whether or not dialysis is required, as well as when and how diagnostic evaluation should proceed; (4) the decision of whether dialysis is necessary or whether correction of obstructive uropathy can begin; and (5) the choice of the best operative procedure for this individual. This article emphasizes the necessity for a multidisciplinary team approach to these patients.

Indications for ureteral stents are mainly malignant ureteral stenoses and obstructive uropathy in high risk patients. In a retrospective study, the experience with ureteral splints in 48 major German hospitals was analyzed for application, results and complications. 323 splints were used in 302 patients for 275 neoplastic or 48 benign ureteral stenoses. Urinary drainage varied between 16 days and 4 years. In 63 patients drainage for more than 1 year was guaranteed. Complications in 164 patients were in decreasing frequency: hematuria, fever, downward migration, kinking of the splint, upward migration, calcification and septicemia. Ureteral stents have to be limited to those cases in which the benefit overrides possible complications.

Fournier's gangrene is a necrotising soft-tissue infection of the scrotum and perineal region caused by gram-negative and gram-positive Enterobacteriaceae. The disease is characterised by its unique appearance, its speed of onset, and its high mortality. CASE REPORT. A 26-year-old male presented to the emergency room complaining of a painful, tremendously swollen scrotum and penis (Fig. 1) that had developed within the past 24 h. Later, slurred speech, pallor, and hypotension were recognised, leading to the patient's admission to the intensive care unit. Suspecting a severe internal haemorrhage, vigorous volume therapy was started using crystalloids and colloids until blood and fresh frozen plasma were available. One hour later, septic shock was presumed and therapy augmented by IV antibiotics, tracheal intubation, and mechanical ventilation. Despite all efforts, the patients condition deteriorated rapidly and he died a few hours later due to multiple organ failure in septic shock. Postmortem, a perforated external hemorrhoidal node was found to be the primary focus of sepsis. Microbiologic cultures revealed Escherichia coli in blood and tissue samples. DISCUSSION. Fournier's gangrene is a rare disease; nevertheless, its clinical picture has to be recognised immediately in order to provide appropriate treatment in time. It occurs predominantly in males after minor trauma, colorectal or urological disease, and perineal or abdominal surgery. Fournier's gangrene usually begins with itching and pain in the scrotal region followed by swelling and dark-blueish discolouration of the scrotum and penis, occasionally including the lower abdominal wall. Fever and chills are usually present. The illness progresses to severe prostation and septic shock with a mortality of 20%-50%. Tissue cultures mostly reveal E. coli, gram-positive enterococci, Pseudomonas, Proteus, and various anaerobes. The treatment should include immediate radical surgical debridement, i.v. administration of broad-spectrum antibiotics, and cardiopulmonary support. CONCLUSION. The dramatic course of Fournier's gangrene requires early recognition, extensive surgical debridement, as well as intensive care treatment in order to prevent irreversible septic shock.

The Dialysis Centre at the Lagos University Teaching Hospital was established in November 1981 as the first unit in West Africa to undertake chronic hemodialysis treatment. More than 500 patients have been managed in the center since then. Of these, 175 were cases of acute renal failure. The causes and outcome of these cases have been reviewed. There were 89 males (50.9%) and 86 females (49.1%). The majority, 111 (63.4%), were aged < 40 years. The main cause was sepsis, which occurred in 67 cases (38.3%). Gynecological and obstetric cases were 45 (25.7%), including 14 cases (8%) of pregnancy toxemia. Other causes were hemorrhage 18 (10.3%), obstructive uropathy 6 (3.4%), acute glomerulonephritis 8 (4.6%), and poisoning with "Holy Water" 6 (3.4%) and other nephrotoxins 9 (5.1%). Sixty-nine patients (39.4%) died in hospital, 92 (52.6%) recovered, and the fate of 14 (8%) was unknown as they were transferred from the hospital. Reasons for the high mortality included delayed hospitalization, selection of severe cases, and inability of patients to afford more than only one session of dialysis even though they needed more. It is hoped that as awareness of the value of dialysis increases and early treatment can be sought, the overall mortality will be reduced.

In a retrospective study, we identified 55 elderly patients with acute renal failure (ARF) admitted to our hospital during an 8-year period from 1985 to 1993. Information about the etiology, complications, laboratory data, and treatment course were obtained from the clinical history. Of the 200 patients with ARF admitted to the hospital during this period, 28% were patients more than 60 years old (41 male and 14 female) with an average age of 68.5 +/- 7 years. The main causes of ARF were sepsis, volume depletion, low cardiac output, arterial hypotension, nephrotoxicity by antibiotics, and obstructive uropathy. The global mortality of elderly patients with ARF was 53%. The mortality rate of the different types of the ARF were: prerenal 35%, intrinsic 64% (oliguric 76%, nonoliguric 50%), and postrenal 40%. Mortality as a result of sepsis occurred in 18 patients (62%), by cardiovascular disease in 4 patients (13%), by acute respiratory failure in 2 patients (7%), and by other causes in 5 patients (18%). In the cases of sepsis, Pseudomonas was detected in 7 cases (39%), Escherichia coli in 2 cases (11%), Gram-negative nonspecific in 3 cases (17%), Klebsiella in 1 case (5%), and in 5 cases (16%), the hemoculture was negative. The patient survival rate was 47% (26 of 55 patients). Of these patients, 19 recovered their normal renal function (73%), but 7 patients remained with renal failure (27%). In conclusion, the global mortality in the elderly patients without considering the types of ARF was 53%. The oliguric form had the highest mortality rate with 76%. The main causes for mortality were sepsis with 62%, cardiovascular disease with 13%, and other causes 18%.

Acute renal failure (ARF) is one of the most frequent and potentially life threatening complications following bone marrow transplantation (BMT). Several renal syndromes that occur are either unique or occur with a disproportionate frequency post-BMT. Clinically ARF can be classified according to the time of onset post-BMT. Immediate ARF syndromes include tumor lysis syndrome and marrow-infusion associated toxicity, which usually occur within 5 days post-BMT. Hepatorenal-like syndrome secondary to venoocclusive disease occur within one month and is the most common cause of early ARF syndrome. The late renal syndromes, more than 4 weeks post-BMT, include BMT-associated nephropathy, which may be acute or chronic, and cyclosporin nephrotoxicity. Other non-specific causes of ARF such as sepsis, hypotension, volume depletion, nephrotoxic agents and obstructive uropathy can also occur at any time period. Frequently ARF is multifactorial in these patients with complicated clinical course. Therapeutic approach depend on the underlying etiology. Supportive treatment such as optimization of volume status and dialysis when indicated are important steps as specific therapy is rarely available. Therefore, efforts should be targeted to the prevention of ARF. This includes prophylaxis for tumor lysis syndrome and marrow infusion toxicity by hydration and alkaline diuresis, avoiding nephrotoxic agents, early recognition and treatment of infection and correction of volume depletion.

The intrauterine surgical placement of vesicoamniotic shunts in the treatment of fetal obstructive uropathy associated with prune-belly syndrome to avoid such complications as renal damage and oligohydramnios remains controversial. We present a case of an infant born with prune-belly syndrome at 33 weeks and 5 days of estimated gestational age to a mother of two by vaginal delivery after a pregnancy complicated by fetal obstructive uropathy with attempted intrauterine intervention. After sonographic and laboratory diagnostic and prognostic evaluations, an intrauterine procedure was performed in which a vesicoamniotic shunt was placed under ultrasound guidance. Complications included dislodgment of the initial shunt, with a failed subsequent attempt at placement, oligohydramnios, preterm labor and delivery, and traumatic gastroschisis through the surgical abdominal wall defect. His hospital stay was further complicated by chronic renal insufficiency, prematurity, respiratory distress, bowel malrotation, an episode of gram-negative sepsis with Enterobacter cloacae, signs of liver failure, an exploratory laparotomy for severe enterocolitis, and orchiopexy for bilateral undescended testes. At present, it is unclear whether vesicoamniotic shunt placement can provide any significant improvement in the morbidity or mortality for patients with prune-belly syndrome. A large, prospective, randomized trial is needed to determine its efficacy.

The epidermolysis bullosa-pyloric atresia-obstructive uropathy (EB-PA-OU) association is a rare, but well-described multisystem disease. While the prognosis at this time is still poor, an increasing number of patients are surviving to adolescence with aggressive care. It is important to understand this syndrome in order to anticipate medical complications and offer preventive strategies where possible. Prompt and expectant management of obstructive uropathy is crucial in these patients. Evidence of ureterovesicular obstruction may require bowel diversion, as excision of the obstructed ureterovesicular junction with reimplantation is often associated with a high risk of reobstruction. Many newborns succumb to sepsis or dehydration and electrolyte imbalance. Those infants who survive need close monitoring for the development of obstructive uropathy, failure to thrive, protein-losing enteropathy, respiratory compromise, and increased susceptibility to invasive infections. Once a clinical diagnosis is made, mutational analysis can confirm it and facilitate genetic counseling, as recurrence risks are 25% for this autosomal recessive condition. Mutational analysis enables direct genetic testing and accurate prenatal diagnosis. As more patients are studied, genotype/phenotype correlations may be possible.

Single-system ureteral ectopia (UE) encompasses a spectrum of malformations involving the bladder trigone, ureter, and kidney. The clinical presentation is variable, and both diagnostic and therapeutic problems are common. Reduced renal function in these patients may result from primary dysplasia, obstruction, vesicoureteral reflux, or recurrent infection. Based on our experience of seven patients, suggestions for diagnostic procedures and criteria for renal saving versus nephrectomy are offered. The relationship between ostium localization, renal function, and long-term results was investigated. From 1972 to 1990, five female and two male patients were studied. During the same period, 31 patients with UE and duplex kidneys were seen. Ages ranged from 1 day to 7 years. A ureteric opening into the bladder neck was associated with dilatation of the ureter and renal pelvis. Two patients had vaginal ectopia and severe renal dysplasia. In one, a cyst of the vaginal wall (Gardner's cyst) was detected at birth. A male newborn had multicystic renal dysplasia on the left and ureteric ectopia to the ductus deferens on the right side. To our knowledge, he is the first patient reported with renal function totally dependent on a kidney with severe UE. Follow-up ranged from 4 to 9 years. One patient died in the postoperative period because of renal failure and sepsis. All the others are well and have normal creatinine values. Improvement of renal function was noted after ureteral reimplantation (URI) in patients with bladder-neck ectopia. The numbers of infections were also drastically reduced. Our observations suggest that the combination of ultrasound, cyst urethrography, and cystoscopy will be diagnostic in most patients. A suspicion of UE should be raised in symptomatic patients with apparently solitary kidneys, enuresis ureterica, or atypical obstructive uropathy. Reduced renal function in some patients with ectopia to the bladder neck will improve after URI. This may be of importance in patients with bilateral anomalies and marginal renal function.
