Ureteric obstruction as a complication to the appendicular abscess. Case report.

In three patients an appendicular abscess caused right-sided ureteric obstruction, and temporary decompression of the upper urinary tract was necessary in two. All recovered completely following combined appendectomy and drainage of the abscess. Since early treatment is essential, the possibility of obstructive uropathy must be kept in mind in the treatment of the appendiceal abscess, especially when nonoperative management is favored.
