[Lower pole pedicle in a series of 84 pyelo-ureteral junction syndromes surgically treated in children].

Objective: To evaluate the involvement and consequences of the lower pole pedicle (LPP) associated with ureteropelvic junction syndrome.

Material And Method: Retrospective study in 81 children presenting a total of 84 ureteropelvic junction syndromes operated consecutively between 1994 and 1998. Urinary tract ultrasound and cystography were systematically performed.

Piezoelectric shockwave lithotripsy of urinary calculi: comparative study of stone depth in kidney and ureter treatments.

Purpose: The aim of this prospective study was to assess the relation between stone depth and the efficiency of piezoelectric extracorporeal shockwave lithotripsy (SWL).

Patients And Methods: A total of 150 patients presenting with 25 pelvic, 75 caliceal, and 25 upper and 25 lower ureteral calculi were treated using the EDAP LT02 lithotripter. All of the stones were easy to localize with sonographic and radiographic systems, and their largest diameter ranged from 4 to 25 mm (mean 8.
