Complications

Renal and ureteric stones can lead to significant morbidity owing to urinary tract obstruction, infectious complications and loss of renal function. Bilateral obstructing ureteric stones or ureteric calculi in a solitary kidney can present with anuria (calculous anuria). Infectious complications include pyelo nephritis, pyonephrosis, renal abscess or septicaemia. Uncom mon but serious complications include XGP and pyeloenteric or cutaneous fistulae in neglected cases. Nephron loss can occur as a result of recurrent episodes of infection and obstruc tion, causing chronic renal failure.
