[Preventive strategies and causes of common complications of ureteroscopy]

To discuss the causes of common complications of ureteroscopy and how to prevent them.

A total of 768 cases of common complications of ureteroscopy were retrospectively analyzed from February 2004 to February 2009.

The intra-operative complications were failed entry (n = 6, 0.78%), ureterostoma injury and ureterostoma submucosa pseudocana (n = 12, 1.56%), ureteral perforation (n = 16, 2.08%), stone displacement (n = 13, 1.87%) and ureteral mucosa evulsion (n = 3, 0.39%). And the post-operative complications were lumbago or renal colic (n = 11, 1.43%), infection (n = 9, 1.17%)and severe hematuria (n = 5, 0.65%).

Skillful operative techniques and strict indications are key to reducing complications of ureteroscopy.
