“…Our initial detected fragmentation rate was 91% overall, 94% for patients harbouring renal calculi and 89% for ureteric calculi. Similar results have been reported by Bergsdorf et al [28] with 94.7% (<5 mm) in 75 patients using the same shockwave delivery system, Pulso11 ® , which was implemented in a Siemens Lithostar Modularis platform in an experimental setup. Seitz et al [12] reported an initial fragmentation rate of 95% in 218 patients using the Lithoskop.…”

Treatment efficacy and outcomes using a third generation shockwave lithotripter

Objectives• To evaluate the clinical efficiency of a third generation electromagnetic shock wave lithotripter, the Lithoskop ® (Siemens, Erlangen, Germany), regarding outcomes, stone disintegration, retreatment and complication rates.• To compare the results of the Lithoskop with other currently available systems and the reference standard lithotripter, the HM-3 (Dornier MedTech Europe GmbH, Wessling, Germany). Patients and Methods• We analysed the data from 183 patients, including 13 children, undergoing extracorporeal shock wave lithotripsy (ESWL) for renal and ureteric calculi collected from a prospectively populated database. • Outcomes were assessed by plain abdominal film of kidney, ureter and bladder and renal ultrasonography for radiopaque and computerized tomography for radiolucent stones 1 day after treatment and after 3 months.• We analysed stone size and location before and after treatment, stone disintegration rate, retreatment rate, stone-free and residual fragment rates after 3 months, along with auxiliary procedures and complications. Results• The mean (range) patient age was 48.6 (1.3-81.4) years, including 13 children with a mean (range) age of 8.4 (1.3-16.7) years, and 77% of the patients were male.• In all, 46% of the calculi were localized in the kidney and 54% in the ureter. Renal stones were localized in the upper, middle and lower calyx and in the renal pelvis in 9, 29, 30 and 32% of patients, respectively. Ureteric stones were localized in the upper, mid-and distal ureter in 29, 19 and 52% of patients, respectively. The median (range) stone size before ESWL was 10 (4-25) mm in the kidney and 8 (4-28) mm in the ureteric calculi.• The overall stone-free rate after 3 months was 91% (88% for renal and 93% for ureteric calculi); the mean number of sessions to achieve these rates was 1.3.• Stone-free rates and the required number of sessions were determined only by stone size. In 7.1% of the patients (n = 13) post-interventional auxiliary procedures were necessary.• We observed one perirenal haematoma as a major complication (0.5%), but this did not require any further therapy. Conclusions• Clinical stone-free rates with the Lithoskop are high and similar to those of other available systems, including the reference standard HM-3 lithotripter.• Retreatment and complication rates are low, supporting the use of ESWL as first-line therapy for urinary calculi <10 mm, independent of stone location.

“…19,20 In nonstented and stented cases with stones 10 mm or less we achieved a SFR of 83.3% and 74.3%, respectively (p ϭ 0.2). The treatment success rate of 93.6% and 97.1%, respectively (p ϭ 0.7), was comparable to that in a prospective preference trial.…”

“…Therefore, electromagnetic shock wave systems were developed with variations in the focal zone, allowing the delivery of greater energy per impulse. 1,18,20 We evaluated and compared the treatment outcome in renal and ureteral stone cases with and without prior ureteral stent placement using the novel Pulso electromagnetic shock wave system integrated into the Lithoskop platform. Its large focal width allows the delivery of increased energy per impulse to the stone and low energy density to minimize adverse effects.…”

Novel Electromagnetic Lithotriptor for Upper Tract Stones With and Without a Ureteral Stent

et al. 2009

View full text Add to dashboard Cite

A high success rate and a low complication rate were achieved in renal and ureteral stone cases with and without prior ureteral stent placement. Total energy needed to achieve a stone-free state did not differ between stented and nonstented ureteral cases, suggesting the absence of a significant influence of the stent. Overall stents decreased complications necessitating hospitalization and auxiliary invasive measures.
