OBJECTIVE
To report the experience with in situ ESWL for patients with middle ureteral stones.


METHODS
52 patients suffering from stones with an average 11 mm (range 5 - 20 mm) in dimension were treated using modified Puigvert technique in prone position via the entry route of lateral abdomen. The patients received 3,000 - 5,000 shocks per session at the power setting ranged from 2 to 7.


RESULTS
The stone free rate at 3 months was achieved in 96% patients retreatment was performed in 30% patients. The therapeutic results were calculated as efficiency quotient being 74%. No severe complications occurred in all patients.
