Patients with refractory ascites and HRS should be considered to present an urgent indication for peritoneovenous shunting. The shunt offers a method of continuous reinfusion of ascitic fluid which corrects avid sodium retention, oliguria and azotemia. Severe encephalopathy, jaundice or peritoneal sepsis--common complications of cirrhosis--contraindicate installation of the shunt before improvement occurs. Associated cardiac disease does not contraindicate the use of the shunt provided that ascitic fluid is removed at the time of operation and large amounts of diuretics are used. This operation has also proved useful in ascites attributed to causes other than cirrhosis. The main complications include disseminated intravascular coagulopathy, hepatic coma and sepsis in a few patients. Results of a randomized prospective study indicate that the shunt should probably be considered in patients with diet-resistant massive ascites even before they prove to be refractory to diuretic therapy.

A retrospective analysis of the results of treatment of advanced rectal cancer of the pelvis with regional intraarterial infusion of 5-fluorouracil (5-FU) is reported. A special technic for positioning the catheters selectively in the internal iliac arteries justifies this analysis. Four patients with primary inextirpable rectal cancer and 10 patients with locally recurrent rectal cancer have been treated. No immediate mortality was noted. Relief of pain was noted in two-thirds of the patients. An objective tumor response was noted in three patients with locally recurrent disease. In one patient with primary inoperable cancer it was possible to extirpate the tumor after infusion therapy. An improvement in quality of life during the first 2 months after therapy was achieved in half of the patients as judged by their performance. Complications were not serious. Hematomas with infection were seen in one patient, two patients had septicemia, and three patients had transient oliguria. Transient thrombocytopenia was reported in two patients. The results indicate that infusion therapy produces a reasonable response such as palliation of pain. Only minor complications were seen and easily controlled. The advantages of infusion therapy are that it can be given in a reasonable time with only a short hospital stay.

A female paraplegic developed intraperitoneal rupture of urinary bladder seven weeks after institution of indwelling urethral catheter drainage. Blockage of the catheter precipitated this fatal event. Oliguria after an initial encouraging urinary output despite adequate fluid replacement led us to suspect bladder rupture which was confirmed by urgent cystography. Although emergency laparotomy to repair the rent in the bladder was performed, she succumbed to gram-negative septicemia. Other hazards of indwelling urethral catheter drainage even for short periods are highlighted (though the above complication itself is admittedly rare) with an oft re-emphasised plea to consider earlier the alternative modality of intermittent catheterisation or pharmacotherapy in female patients.

Over a period of 2 years, 82 patients out of 2,390 (3.43%) admitted to an intensive care unit developed acute renal failure (ARF). The diagnosis of ARF was based on the usual criteria of oliguria, a rising blood urea nitrogen and creatinine, urine sodium concentration greater than 20 mmol/l and a U/P osmolality ratio less than 1.1. In 9.2% of patients the latter two criteria were misleading. Sepsis was the commonest cause of vasomotor nephropathy but in 20.7% potentially nephrotoxic agents had been administered before development of ARF. Overall mortality was 73.2%, with patients older than 50 years of age having the highest mortality. ARF is associated with prolonged bed occupancy--an average of 59.8 days for the dialysed patients with ARF versus an average length of stay of 8.4 days for the hospital overall.

Oliguria, an easily recognizable symptom of postoperative acute renal failure, is analyzed schematically in terms of various diagnostic aspects and a pragmatic therapeutic procedure. Differentiation among pre-, intra-, and postrenal disturbances is important. Acute renal failure caused by simultaneous and often severe insufficiency of other organs, especially in combination with septicemia, still has a bad prognosis. Prophylaxis in the form of adequate volume substitution and shock therapy is urgent in each case.

Twenty infants and young children with hereditary fructose intolerance (HFI) were admitted to hospital. None was diagnosed at admission. Referals were for vomiting of unknown aetiology (16X), pyloric stenosis or hiatus hernia (5X), toxic condition (3X), and hepatomegaly of unknown origin (5X). Feeding difficulties (20X), vomiting (18X), and failure to thrive (16X) were leading symptoms. The most frequent clinical findings were hepatomegaly (18X), pallor (14X), haemorrhages (13X). Ascites, oliguria, tachypnoea, fever, splenomegaly and rickets were less frequent. Laboratory findings were indicative of disturbed hepatic and renal tubular function and also of disturbed intermediary metabolism (hypokaliaemia, hypophosphataemia). However, hypoglycaemia was found in only 4 out of 15 patients tested. Differential diagnosis after hospital admission centered on metabolic disorders such as glycogenoses, galactosaemia, tyrosinosis, or Wilson's disease. Hepatitis, toxic hepatosis, liver tumour, intrauterine infection and sepsis were also considered. Eleven children had first ingested fructose within the first 6 weeks of life. The diagnosis was usually established only many weeks or months after first fructose intake and appearance of symptoms. This documents how difficult the diagnosis of this disease can be both in practice and in hospital. The course was severe in 11 children and lethal in 4. In only 5 patients was the course mild. The 16 survivors are doing well under fructose-exclusion diet. Irreversible visual impairment after intraocular haemorrhage occurred once. In each case HFI could have been suspected immediately, had a detailed nutritional history been taken. Practising paediatricians should know the composition of commonly used infant formulae. They should never prescribe sugared condensed milk for intractable vomiting prior to excluding HFI. Solution for intravenous infusion containing fructose and sorbitol are life-threatening for undiagnosed HFI patients.

An active approach to severe renal lithiasis is advocated, though operative procedures often require interruption of the blood supply. Te evaluate the effect of ischemia on the kidney the literature has been searched and we have reached the following conclusions. A warm ischemic time of more than 20 minutes causes a brief and transitory reduction in renal function. If ischemia exceeds 30-40 minutes many kidneys will not regain their previous function. If the kidney's temperature is lowered to about 15 degrees C, ischemia can be tolerated for up to 12 hours. A priori these time limits applicable to normal kidneys are to broad for use in diseased kidneys. Cooling of the kidney can be achieved by either perfusion-cooling or by external parenchymatous cooling. We describe a method using the latter system for stone removal in 14 patients with staghorn calculi or multiple stones. Preoperatively 9 patients (64%) had persistent urinary tract infection, whereas infection persisted in only 2 patients following the operation (14%). Complete stone removal was achieved in 13 patients (93%). Renal function evaluated by creatinine clearance and renography generally improved following operation. There were no deaths, but in 9 patients severe complications were seen (transient oliguria and septicemia). At follow-up investigation 1.5 years after operation renewed stone formation was found in 1 patient, while the incidence of urinary tract infection had increased to 3 patients (21%). It is concluded that extensive surgery for stone removal with the use of external parenchymatous cooling is worthwhile and promising in patients with staghorn calculi or multiple stones in the kidneys.

One hundred fifty of 490 patients undergoing open heart surgery had renal failure attributable to cardiopulmonary bypass. In 69, serum creatinine concentrations did not exceed 2 mg/dl and returned to normal by the fourth postoperative day. In 60 patients, serum creatinine attained levels between 2 and 5 mg/dl, oliguria did not develop, and recovery of renal function occurred within 4 to 37 days. Serum creatinine increased to levels exceeding 5 mg/dl in 21 patients, 11 of whom were oliguric. Despite dialysis, 14 of these patients died from cardiac causes or sepsis. Prolonged cardiopulmonary bypass time, hypotension, oliguria, low output syndrome, and hemoglobinemia during open heart surgery correlated with the development of renal failure postoperatively. Although severe renal failure was an uncommon complication after open heart surgery, its occurrence carried a grave prognosis.

The acute onset of oliguria and azotemia in the postoperative setting may be caused by pre-renal causes or intrinsic renal damage. The first step in arriving at a diagnosis is to review the history as noted above for clues regarding fluid balance, treatment with nephrotoxins, etc. The typical patient with prerenal azotemia will present with evidence of the recent onset of worsening of pre-existing cardiac disease, renal or gastrointestinal fluid loss, or the accumulation of acites, edema, or retroperitoneal fluid. In the absence of very recent diuretic therapy, he will be excreting a scant amount of concentrated (greater than 400 mOsm per L) sodium free (less than 10 to 20 mEq per L) urine. The serumBUN/Cr ratio is often greater than 15 to 20:1, and their urinary sediment will be bland. In an occasional patient in whom these studies give equivocal results, additional help may be obtained with measurements of central venous pressure (CVP) or pulmonary wedge pressure (PWP) and by noting their response to intravenous fluid loading. A rising CVP or PWP in the face of salt loading is, of course, evidence against prerenal azotemia. Patients with obstructive uropathies may be oligoanuric or polyuric-occasionally a characteristic alternating polyuria and oliguria is found (due to displacement of a stone or relief of edema). When oliguric their urine typically contains substantial amounts of sodium (greater than 20 mEq per L), is isotonic, and their OsmU:OsmP is les s than or equal to 1.2. Their urinary sediment will reflect the cause of their obstruction as noted above. A renal scan, ultrasound study, or infusion IVP are mandatory to rule out the possibility of obstructive uropathy. If these nonivasive studies are equivocal, one must consider doing a unilateral retrograde. The development of ATN usually occurs in the setting of hypotension, sepsis, dehydration, and with exposure to nephrotoxins. Most patients with be excreting scant amounts of isotonic urine containing more than 20 to 30 mEq per L of sodium. Their CrU:CrP is less than or equal to 20:1 and their urinary sediment reveals many epithelial cells and casts. Those patients with nonoliguric ATN have urine outputs which may exceed 2 liters per day. Despite this output they demonstrate a stepwise increase in serum urea and creatinine. Urine sodium and osmolality are not very helpful in this setting. Many such patients do have low (less than 20 mEg per L) urine sodium concentration and excrete isotonic urine.

The mortality in 25 patients suffering from post-combat injury acute renal failure (ARF) was 64%. Abdominal injuries were present in 17 patients with a mortality rate of 64.7%. Respiratory insufficiency occurred in 14 patients, jaundice occurred in 13, and septicemia in 10. The mean period of oliguria was high, 24.1 days per survivor, and the number of hemodialyses averaged 21.6 per survivor. It is concluded that the high mortality is primary due to the severity of the underlying injury itself and not due to the renal failure, that the ARF is more severe than in civilian injuries, as evidenced by a prolonged oliguric phase, and that frequent and intensive hemodialysis regimen is necessary for the elimination of deaths from uremia per se.
