Piezoelectric lithotripsy monotherapy for partial or total staghorn lithiasis and calculi larger than thirty millimeters.

Thirty patients with partial or total staghorn lithiasis or calculi larger than 30 mm were treated by piezoelectric lithotripsy (PEL) monotherapy using an EDAP LT-01 lithotripter with ultrasound guidance. Nineteen of these patients had a pelvic stone; the other 11 had partial (nine) or total (two) staghorn lithiasis. All patients first underwent an initial lithotripsy session.

[Exclusive piezo-electric lithotripsy (EDAP LT 01) in the treatment of calculi larger than 30 mm. Pyelic, partial or total staghorn].

Thirty patients with partial of total staghorn calculi or pyelic calculi greater than 30 mm were treated by extracorporal piezo-electric lithotripsy (PEL) exclusively with an EDAP LT 01 lithotripter equipped with an ultrasound localisation system. Nineteen patients had a pyelic calculus and the others a partial (n = 9) or total (n = 2) staghorn calculus. All patients first underwent extracorporal lithotripsy (ECL).

[Extracorporeal piezoelectric lithotripsy in the treatment of calculi of the ureter. Apropos of a series of 143 cases].

The results obtained in 143 cases or ureteral stones treated by EDAP LT-01 were analysed concerning stone location, ureteral manipulation, and treatment position. The ureter was divided into six segments: ureteropelvic junction (UPJ), proximal ureter higher than the lower pole of the kidney (PU1), proximal ureter between the lower pole and the iliac crest (PU2), mid-ureter between the iliac crest and the lower end of the sacroiliac joint (MU), distal ureter between the lower end of the sacroiliac joint and the ischial spine (DU1), and the distal ureter below the ischial spine to the meatus (DU2). The overall fragmentation rate (FR) was 72%, as detailed below: (table; see text) Anesthesia or iv sedation was never used for EPL.

The results for 143 cases of ureteral stones treated by EDAP LT01 were analyzed concerning stone location, ureteral manipulation and treatment position. The ureter was divided into six segments: ureteropelvic junction (UPJ), proximal ureter (PU1 and PU2), mid-ureter (MU), distal ureter (D1 and D2). The overall fracturization rate (FR) was 72%, as detailed below: UPJ (89%, 26/29), PU1 (86%, 13/15), PU2-MU (62%, 15/24), DU1 (59%, 25/42), DU2 (72%, 24/33).

[Intraprostatic spiral for the treatment of benign prostatic hypertrophy. A new method of insertion with sonographic monitoring. Apropos of 35 patients].

The treatment of subvesical obstruction with a spiral endoprostatic prosthesis is now well-known since Fabian's initial work (1980). A new method of insertion of the spiral with a releasable catheter and under sonographic monitoring has been proposed recently. This article is a report of a series of 35 patients.
