Extracorporeal shock wave lithotripsy monotherapy for bladder stones

Abstract

This report presents our initial experience in 36 patients with bladder stones, treated by extracorporeal shock wave lithotripsy. Minute fragmentation and uncomplicated evacuation occurred in 26 patients (72%). Mean treatment duration was 55 minutes. Mean number of shock waves was 3600 and electrical discharge averaged 24 kV per shock wave. No morbidity, during or after treatment, was encountered in these patients. The treatment was performed without the use of anaesthesia on an outpatient basis.

“…A cystoscopy was necessary to evacuate the calculi in 17% of patients. Kostakopoulos et al 14 reported 72% of patients free from calculi after ESWL in a series of 36 cases. Garcia Cardoso et al 15 performed ESWL in 45 patients and, after one to five sessions, 99.4% of patients were free of lithiasis, 13% of patients requiring cystoscopy assistance.…”

“…Fragmentation is obtained from sources of mechanical/ ballistic, ultrasonic, electro-hydraulic or laser energies. Several studies have demonstrated the superiority of the holmium: YAG laser compared to other lithotripsy methods [14][15][16][17][18][19] . Un-in et al 18 compared 23 patients undergoing lithotripsy with holmium: YAG laser with ten patients treated with ballistic lithotrispy.…”

Management of bladder stones: the move towards non-invasive treatment

“…7,8 Many previous studies presented promising data on its efficacy as a monotherapy in bladder stone. [9][10][11] Therefore, this retrospective study is conducted to explore the safety and effectiveness ofbladder stone management in the Cipto Mangunkusumo General Hospital (RSCM) who underwent ESWL. Patients who underwent ESWL were treated on supine position using PiezoLith 3,000 Plus -Richard Wolf.…”

The use of ESWL as a monotherapy in bladder stones, however, still has some controversial issues to address.…”
