Urodynamic studies were carried out in a 14-year-old boy with Prune Belly Syndrome and terminal renal failure prior and after successful renal transplantation. Increased bladder capacity, nonprovocative detrusor instability and a high compliance were the most characteristic findings during the filling phase of the bladder. During the voiding phase an increased detrusor pressure was demonstrated. Outflow resistance and maximum urinary flow rate were within normal range before and after transplantation. In contrast to the findings before renal transplantation, however, micturition was imbalanced after transplantation (residual urine 100 ml). Urodynamics revealed that the bulging of the posterior urethra, observed in the early voiding phase, was due to a congenital insufficiency of the posterior urethral musculature (megalourethra) and not caused by mechanical obstruction leading to urethral dilatation. It is suggested that detrusor-bladder-neck-dyssynergia is the primary cause of the imbalanced micturition and its consequences (bladder distention, reflux, urinary tract infection, hydronephrosis, pyelonephritis) in patients with Prune Belly Syndrome. The findings of a normal, respectively increased detrusor activity are in contrast to the observations of some authors, describing attenutation and absence of detrusor muscle fibres. The indications and effects of transurethral resection and internal urethrotomy, proposed by some authors, are discussed.

Seven patients on dialysis with renal failure received transplants from mismatched cadaver donors and were treated with cyclosporin A (CyA), initially as the sole immunosuppressive agent. CyA was effective in inhibiting rejection but there was clear evidence of both nephrotoxicity and hepatotoxicity. A cyclophosphamide analogue was added to the CyA treatment in six of the patients. Five patients are out of hospital with functioning allografts, and two of these have received no steroids. One patient required an allograft nephrectomy because of pyelonephritis in the graft. Another died of systemic aspergillus and candida infection. Further careful study of this potentially valuable drug will by required before it can be recommended in clinical practice.

A 59-year-old woman with end-stage renal failure due to chronic pyelonephritis developed Candida albicans peritonitis after receiving chronic intermittent peritoneal dialysis for 4 months. She was successfully treated with 5-fluorocytosine added to the dialysis fluid.

The surgical riks were analyzed in 305 patients with end stage renal failure who underwent bilateral nephrectomy through midabdominal approach in preparation for kidney transplantation. The over-all mortality rate was 3.6 per cent. Age was the most significant risk factor in the mortality. Patients less than fifty years of age had an operative mortality rate of 3.1 per cent while those more than fifty years had an operative mortality of 11.1 per cent. Other pertinent risk factors were preoperative complications of renal failure and additional surgical procedures at the time of bilateral nephrectomy. The leading causes of death were those of cardiovascular complications and infection. The morbidity rate was 58.7 per cent being major in 18 per cent and minor in 40.7 per cent. Bilateral nephrectomy is recommended selectively in patients with (1) chronic pyelonephritis with urinary tract infection, (2) major vesicoureteral reflux, (3) immunologically active glomerulonephritis, (4) severe hypertension uncontrollable by adequate dialysis, and (5) extremely large or infected polycystic kidneys.

The pattern of renal disease and its basic principles of management are essentially the same in the tropics as in the temperate environment. Glomerulonephritis and pyelonephritis with concomitant hypertension account for most cases of renal failure. Malaria is now well recognised as a cause of the nephrotic syndrome. Economic and manpower factors dictate a conservative approach to therapy. Maintenance haemodialysis and renal transplantation are not realistic in the present context, having regard to the order of priorities in health care delivery.

Five patients who presented with acute renal failure in association with urinary tract infection are reported. Renal function improved rapidly on antibacterial therapy and no alternative cause for acute renal failure could be identified. None had previously been known to have renal disease but three of the five had taken considerable amounts of analgesics. The unusual severity of renal functional impairment resulting from urinary tract infection in these patients is unexplained but may relate to previous analgesic abuse and/or delay in treatment. Since acute non-obstructive pyelonephritis may result in severe reversible renal failure, this diagnosis must be considered in patients presenting with acute uraemia.

Trigonal-colonic anastomosis for diversion of urine into the colon was performed in 12 clinically normal dogs and in 10 incontinent dogs with diseases of the urinary bladder or urethra. Dogs were studied from 1 to 30 months after surgery. The surgical procedure was technically satisfactory. Fifteen of 22 dogs were studied with intravenous urography, and only 1 case of hydronephrosis was found. Pyelitis was a common histopathologic finding in both groups of dogs. Pyelonephritis developed in 30% of dogs, regardless of duration of anastomosis. Glomerular filtration rate was reduced in all dogs studied, but renal failure was infrequent. Values for blood urea nitrogen and serum inorganic phosphorus were elevated due to intestinal recycling of nitrogenous products and phosphate. Electrolyte imbalances were not a problem, but gastrointestinal disturbances developed in 3 of the 10 diseased dogs. Six of 10 diseased dogs survived from 9 months to more than 3 years. Trigonal-colonic anastomosis appears to be a satisfactory salvage procedure for incontinent dogs with diseases of the urinary bladder or urethra that do not respond to other forms of therapy.

Complications are the major causes of illness and death after burning and most of them stem from the burn wound. Their origin and importance are reviewed with emphasis on problems and growing points in knowledge. Fluid leakage from the circulation into the burn is the cause of hypovolemic shock, but the underlying permeability changes in the burn are only partly understood. Other nonbacterial complications include acute cardiac failure, acute anemia, hemolytic jaundice, renal failure, encephalopathy, complex hypermetabolic effects including pseudodiabetes, gastric and duodenal ulceration, deep vein thrombosis and pulmonary embolism, pulmonary and glomerular microthrombosis, hepatic jaundice, and arterial thrombosis. Involvement of the airway in conflagrations carries special hazards like glottic edema and inhalation of irritant fumes. Nowadays, bacterial causes are dominant and these remain the main challenge. Bacterial infection and invasion of the burn are usually responsible for septicemia, bronchopneumonia, and pyelonephritis although other sources also contribute. Indirect manifestations of septicemia include paralytic ileus, acute gastric dilatation, toxic myocarditis, and some cases of renal failure. Therapeutic complications like agranulocytosis, thrombocytopenia, and colitis occur at times. High concentrations of oxygen given therapeutically can produce fatal aseptic hypoxic pneumonitis.

Six patients with fetal alcohol syndrome were found to have developmental abnormalities of the kidney. In only one patient was investigation for renal pathology made in the absence of clinical indication. Two had palpable masses in the left upper quadrant, one had pyelonephritis, one had painless hematuria, and the fifth patient had symptomatology suggestive of renal failure. Although the renal pathology was not of the same type in all cases, it is of interest that four patients had either unilateral or bilateral renal hypoplasia.

A 4-year-old girl, who had been in perfect health, presented with the acute onset of renal failure and abdominal mass. Investigations revealed a solitary left kidney which on histology had the typical features of xanthogranulomatous pyelonephritis. The child had no previous history suggestive of chronic renal disease and had no radiologic evidence of renal osteodystrophy. She had no improvement in renal function and has gone on to hemodialysis and transplantation. The unique mode of presentation and the unusual features of this case are discussed.
