A previously healthy 2.5-year-old boy developed symptoms of acute pyelonephritis following an acute gastroenteritis. The patient received parenteral ampicillin and gentamicin for 72 hours and then ampicillin for an additional 11 days when the original urine and stool cultures grew Salmonella enteritidis, sensitive to ampicillin. The patient responded very well to treatment, but B-mode renal ultrasonogram revealed a left hydronephrosis and megaureter suggestive of longstanding obstruction of the ureterovesicular junction, later confirmed by other diagnostic studies and by surgical exploration and repair. Salmonella infection has been rarely documented to cause pyelonephritis in children. Obstructive uropathy appears to be a predisposing factor for this unusual complication of Salmonella enteritis.

A total of 638 patients with acute renal failure (ARF) of diverse etiology were studied over a period of 9 years (July 1985-Dec, 1994) of which 96 (15%) patients were classified as elderly ARF with mean age of 72.5 years. Medical causes accounted for 80% of geriatric ARF while 20% patients, had ARF of surgical origin. Decreased renal perfusion resulting from gastroenteritis was the predominant (52.8%) cause of ARF in the medical group. Nephrotoxic ARF and ARF due to F. malaria were seen in 10 and 7 patients respectively. Obstructive uropathy was observed in 12 patients in surgical group and in remaining 8 patients ARF developed following various surgical procedures. ARF in association with multiorgan failure was not observed in our study. Mortality was seen in 24 patients (25%). The causes of mortality were GI bleed (6), peripheral circulatory failure (5), hyperkalemia (4) and sepsis (4). Thus medical ARF remains the major cause of acute renal failure in elderly patients in our study in contrast to ARF associated with multiorgan failure and surgery in developed countries.

Rotavirus (RV) is a common pathogen that causes acute gastroenteritis in childhood. Some cases with RV infection also have prerenal renal failure induced by dehydration associated with vomiting and diarrhea. Here, we report 4 patients with RV infection who developed postrenal renal failure induced by urinary tract obstruction with uroammoniac calculi or crystals. The patients did not have metabolic disorders or abnormalities of the urinary tract, and increased urinary excretion of uric acid was not recognized at discharge. In addition, no abnormalities in the uric acid transporter (URAT1) were found in any of the patients. Uric acid stone formation was considered to have originated from the low pH caused by dehydration and the increase of urinary uric acid excretion from damaged cells.

Acute gastroenteritis with viral infection in infants causes severe diarrhea and often results in acute renal failure due to severe dehydration. However, a viral infection, particularly rotavirus, rarely induces postrenal failure due to bilateral stones in infants. Herein, we report three cases of postrenal failure in infants due to bilateral ureteral stones induced by acute gastroenteritis with rotavirus. Following immediately nephrostomy, chemical dissolution therapy succeeded to treat postrenal failure. Immediate nephrostomy for the release of upper urinary tract obstruction combined with urinary alkalization as a chemical dissolution therapy should be considered in such cases.
