Ureterosigmoidostomy and obstructive uropathy.

BACKGROUND

A 19-year-old mentally retarded man with failed exstrophy repair and ureterosigmoidostomy urinary diversion presented with high fever, vomiting and right-flank pain of 2 days' duration. Past medical history was notable for a left nephrectomy to treat an infected staghorn calculus in a poorly functioning kidney. Physical examination revealed pyrexia and right-flank tenderness.

INVESTIGATIONS: Physical examination, renal function tests, electrolyte and metabolic assessment, urine and blood cultures, abdominal CT, ANTEGRADE PYELOURETEROGRAPHY, sigmoidoscopy and histopathology.

DIAGNOSIS: Ureterosigmoidostomy complicated by acute pyelonephritis, obstructive uropathy, recurrent urinary tract infections, renal impairment and the development of renal stones and metabolic acidosis.

MANAGEMENT: Fluids, intravenous antibiotics, bicarbonate and potassium supplementation, and rediversion of ureterosigmoidostomy to an ileal conduit.
