Clinical Experience with a new Pulsed Dye Laser for Ureteral Stone Lithotripsy

Abstract: We treated 45 patients (46 ureteral stones) with a new pulsed dye laser. A 250 mu. fiber was used through a rigid (40 stones) or flexible (6) ureteroscope. Stones were in the upper (5 cases), middle (5) or lower (36) third of the ureter. Stone composition was calcium oxalate dihydrate (34 patients) or monohydrate (7), struvite (2) or uric acid (2). Of the calculi 36 (78%) were fragmented, including 14 that also required simultaneous basket removal of fragments. Ten stones were not fragmented: 6 because of the … Show more

“…The early laser generators were capable of fragmenting most stones but they did not break some of the harder calcium oxalate monohydrate calculi (Zerbib et al, 1990;Vandeursen et al, 1991). More powerful laser sources have now become available and we report our experience with the Candela MDL-2000 Lasertripter and the Candela 7.2F Miniscope.…”

“…For upper pelvic calculi, opinions vary. Some authors feel that pelvic stones are amenable to ureteroscopic extraction (Coptcoat et al, 1987 ;Ikemoto et al, 1988;Zerbib et al, 1990), but we believe it is simpler to use ESWL first.…”

“…Hochflexible Lasersonden ermöglichen die Lithotripsie über flexible Ureteroskope und damit prinzipiell die ureteroskopische Steinsanierung des gesamten oberen Harntraktes. Farbstoff-Laser konnten sich überwiegend wegen den immensen Anschaffungs-und Wartungskosten sowie der selektiven Wirksamkeit nicht durchsetzen [1,2]. Der Holmium-Laser zeigt zwar eine gute Desintegrationsleistung, ist aber durch die Gefahr der Perforation von Ureterwand bzw.…”
