“…In our hands, in this study, electrohydraulic shock waves achieved a success rate of 62%, a figure much lower than those published by Willscher et al [14], Denstedt and dayman [13], and Begun et al [12], who reported success rates of 100, 91 and 83%, respectively. The small er diameter of the stones (mean diameter of 8 mm) in Willscher's and Denstedfs studies could partly explain to the smaller dimensions of the stones.…”

“…well documented, but in adults convincing evidence for the safety of intramural dilatation was documented by EHL was the primary mode of fragmentation used in the present series; it has been found to be safe and eÂective Garvin et al, who reported no clinically significant longterm sequelae from routine dilatation of the ureteric for fragmentation of ureteric calculi in adults [14,15]. It is a powerful shockwave source which can be delivered orifice to 24 F [7].…”

Objective To study the eÃcacy and safety of ureterosand 97% of the procedures in the upper, mid and lower ureters, respectively. In three children the procedure copy in the management of paediatric ureteric calculi at various levels. failed and they were salvaged by ureterolithotomy. During the procedures, an upper ureteric Patients and methods The records of 50 ureteroscopic procedures performed on 43 children (age range 6 perforation occurred in one patient and a lower perforation in another. MCUG revealed low grade vesicomonths-12 years) for primary ureteric calculi or ureteric fragments after electrohydraulic shockwave lithotripsy ureteric reflux in 17% of the patients, but close followup showed the reflux to be sterile and clinically (EHWL) were analysed retrospectively. The distribution of the calculi was in nine in the upper upper, seven in insignificant. Conclusion Ureteroscopy was safe and eÂective for the the mid and 30 in the lower ureter, with a mean stone burden of 1.26 cm. Ureteroscopy was performed with management of mid and lower ureteric calculi but the results for upper ureteric calculi were marginally the 8.5/9.5/11.5 F Wolf ureteroscopes, and EHL was used as the primary method of fragmentation.inferior. Ureteroscopy must be performed judiciously to minimize ureteric injury in children. The incidence Intravenous urograms were available in 34 children (79%) and micturating cystography (MCUG) was perof vesico-ureteric reflux after mechanical dilatation of the intramural ureter was infrequent and clinically formed in 23 children (54%) during the follow-up. Results An overall stone-free status was achieved in 40 insignificant. Keywords Electrohydraulic lithotripsy, paediatrics, children (93%) after performing 47 ureteroscopies (94%). Stones were completely cleared in 78%, 100% ureter, ureteric calculi, ureteroscopy in 43 children with ureteric calculi to evaluate the safety

“…Despite technical improvements and extensive clinical experience, especially in bladder and ureteric stones, EHL has the narrowest margin of safety. If the electrode is discharged when not in contact with the stone, the spark can damage the ureteroscope lens or the collecting system, and cause major intrarenal bleeding [5].…”
