Overview of the handling of extracorporeal shock wave lithotripsy for disintegration of urinary tract stones.
Different international associations have proposed their own guidelines on urolithiasis. However, the focus is primarily on an overview of the principles of urolithiasis management rather than step-by-step technical details for the procedure. The International Alliance of Urolithiasis (IAU) is releasing a series of guidelines on the management of u...
It is well recognized that the popularity of extracorporeal shock wave lithotripsy (SWL), despite its non-invasive character, has decreased during recent years. This is partly explained by the technological achievements in endoscopy and urologists’ enthusiasm for such procedures. Another explanation is that many urologists have been insufficiently...
With a prevalence of 2–3%, urolithiasis is one of the most common diseases. Currently there is no causal therapy against the forming of stones. Until 35 years ago, when the first patient was treated with extracorporeal shockwaves and kidney stones were reduced to a size which permitted the fragments to be passed naturally, it required a surgical in...
Prostate cancer is diagnosed 10 years earlier and men
live almost 4 years longer than 30 years ago. This means
that the therapeutic necessity is more than double the
time than it was then. None of the classical therapies is
effective enough to cover this time frame as a
monotherapy without a significant risk of aggressive
recurrence during these ye...
Over the past 25 years, the average life expectancy for men has increased almost 4 years, and the age of prostate cancer detection has decreased an average of 10 years with diagnosis increasingly made at early-stage disease where curative therapy is possible. These changing trends in the age and extent of malignancy at diagnosis have revealed limit...
Objective:
To report the oncological outcome of Salvage high-intensity focused ultrasound (S-HIFU) for locally recurrent prostate cancer (PCa) following External Beam Radiotherapy (EBRT) from a multicenter database.
Materials and methods:
This retrospective study comprises patients from 9 centers with local recurrent disease following EBRT treat...
We performed extracorporeally induced destruction of kidney stones on 72 patients. No complications have resulted from the tissue exposure to high energy shock waves. Clearance studies before and after the shock wave treatment indicate no changes in renal function. The method was used successfully in all patients with stones in the renal pelvis. In...

ESWL still remains the least invasive treatment modality for any urinary stone.
With proper equipment, an understanding of the basic physics of shock waves and adequate training in
the safe application of shock wave energy, results are excellent with minimal complications.
In order to achieve optimal treatment results with ESWL,
an understanding...
At a time when there is an almost unlimited enthusiasm and preference among urologists for endoscopic stone removal, we have found it essential to meet some of the frequently presented arguments on why extracorporeal shockwave lithotripsy (SWL) should not be used. We have based our considerations in this brief article on our 30-35 years' experience...
Although shock wave lithotripsy (SWL) remains an excellent non-invasive method for active removal of stones from the ureter and kidney, its popularity has decreased during recent years and the arguments for choosing endoscopic procedures rather than the only non-invasive surgical procedure are usually based on the opinion that SWL results are infer...
Following its introduction in the 1980s extracorporeal shock wave lithotripsy (SWL) became the gold standard for therapy of ureteral and renal calculi. The research data published during the last decade suggest a paradigm shift to endourological techniques.
The purpose of this study was to compare whether the suggested loss of status for SWL corres...
The attraction of robotic high-intensity focused ultrasound (HIFU) is mainly based on its noninvasive, precise quality of high-tech robotic therapy. For 18 years, HIFU is applied clinically as a therapeutic tool for the treatment of prostate cancer using a transrectal ablation technique.
HIFU’s clinical investigation started in the 1990s and led to...
Background and purpose:
Shockwave lithotripsy (SWL) is the gold standard treatment of patients with most renal and proximal ureteral calculi. Severe bleeding complications in SWL are extremely rare. Uncorrected bleeding diathesis might increase the risk and is considered to be an absolute contraindication for SWL. Perioperative management of antic...
ESWL still is the least invasive treatment modality for any urinary stone. Mainly due to a lack of proper training results with ESWL are often poorer than expected, inciting urologists to choose for more invasive endourologic treatment modalities for their patients. With proper equipment, an understanding of the basic physics of SW and adequate tra...
Shock wave lithotripsy (SWL) is the gold standard for the treatment of upper urinary tract stones. Despite being relatively non-invasive, SWL can cause renal hematoma (RHT). The aim of this study was to determine incidence and risk factors for RHT following SWL. 857 patients were included in a prospectively maintained database. The observation peri...
The introduction of new lithotripters increased problems of shock wave application. Recent studies concerning mechanisms of stone disintegration, shock wave focussing, coupling and application have appeared that may address some of these problems. Moreover, manufacturers have introduced new devices with significant modifications.
The theory of dyna...
Purpose:
We describe the long-term cancer control and morbidity of high intensity focused ultrasound with neoadjuvant transurethral resection of the prostate, the risk of metastatic induction by transurethral prostate resection, and the evolution of high intensity focused ultrasound application and technology with time.
Materials and methods:
A...
Shock wave lithotripsy still remains the only noninvasive treatment modality for urolithiasis besides conservative stone management. Overall it has high efficacy, comfortable application without the need of general anesthesia, low rate of side effects, and high patient acceptance. To obtain the best results, careful attention has to be paid to choi...
A number of considerations are necessary for an optimal result of extracorporeal shock wave lithotripsy. In this chapter, we present some examples of patients that pose specific problems that need to be identified and appropriately dealt with in order to achieve the desirable result of a satisfactory disintegration without serious complications. It...
The present review summarizes the most important considerations and steps for an optimal result of extracorporeal shockwave lithotripsy. The relationship between shockwave path, geometry and anatomical conditions is of utmost importance. Selection of appropriate treatment variables in terms of shockwave number, power and frequency, is an important...

The @-Registry includes data from consecutive patients treated with Ablatherm (EDAP-TMS) HIFU at nine European Centres during the period 1994 an...
Interest in the technology of high-intensity focused ultrasound (HIFU) is based largely on the noninvasive nature of therapy. In urologic oncology, HIFU is used as a therapeutic tool for treatment of prostate and kidney cancer. While the treatment of renal cancer is still being tested in experimental and clinical studies, HIFU therapy of prostate c...
The application of a water-jet dissector for mucosal elevation was shown to improve resection of lesions of the gastrointestinal tract. We present the first prospective clinical trial on the application of a combined water-jet dissector and needle-knife (HybridKnife) in transurethral dissection (TUD) of urothelial carcinoma of the bladder (UCB).
Th...
Attractivity of robotic high intensity focused ultrasound (HIFU) is based largely on the non-invasive, extremely precise nature of this high-tech robotic therapy as well as its clean, radiation free, surgical, but nevertheless, bloodless character. Today, in urological oncology, HIFU is used clinically as a therapeutic tool for the treatment of pro...
High-intensity focused ultrasound (HIFU) is an emerging, noninvasive, local treatment of prostate cancer with 15 years of clinical experience, during which about 30,000 HIFU treatments have been performed worldwide. In this paper, we review relevant publications regarding the means by which new and old prostate cancer technologies are evaluated, th...
The introduction of new lithotripters has increased problems associated with shock wave application. Recent studies concerning mechanisms of stone disintegration, shock wave focusing, coupling, and application have appeared that may address some of these problems.
To present a consensus with respect to the physics and techniques used by urologists,...
Positive lymph node (LN) status is considered a systemic disease state. In prostate cancer, LN-positive diagnosis during pelvic LN dissection (PLND) potentially leads to the abandonment of radical prostatectomy (RP).
To compare the overall survival (OS) and relative survival (RS; as an estimate for cancer-specific survival) in LN-positive patients...
The treatment of localized prostate cancer with high-intensity focused ultrasound (HIFU) has been researched since the 1990s and today the treatment is an actively used therapy for the disease. HIFU works in two ways to destroy tissue, namely thermal and mechanical effects. The most recent data on the Ablatherm HIFU device come from an internationa...
In one-third of patients, prostate cancer (PCa) is monofocal. These patients can undergo focal high-intensity focused ultrasound (HIFU) therapy of the tumor without damage to surrounding structures and not compromising uro-oncologic safety. Robot-assisted HIFU coagulates the entire targeted volume within the prostate transrectally, in one session,...
Shock waves are acoustic waves generated by a spark or an electric coil mounted in a membrane or piezoceramic element (electrohydraulic lithotriptor [EHL], electromagnetic lithotriptor [EML], piezoelectric lithotriptor [PEL]), propagated through water and are focused on the stone. Focal width, wave peak pressure and rate delivery play a major role...
