[The bladder-stone punch--a new principle of visual lithotripsy (author's transl)].

Description of a bladder-stone lithotriptor which works similarly to a punch resectoscope. This 24 French instrument can be used in simultaneously with electrohydraulic lithotripsy (Urat I), i.e., stones of the size of a cherry can be simply punched, while all larger stones may be destroyed first by electrohydraulic lithotripsy and then cut into smaller pieces for removal with the punch. The instrument, with irrigation qualities and a sight like a resectoscope, allows a quick operation, so that lithotripsy and TUR of the prostate may be performed opportunely.

Endoscopic lithotripsy in the common bile duct.

After appropriate preliminary experiments in animals and in corpses, electrohydraulic lithotripsy has been used for the first time in humans in an attempt to destroy stones in the bile duct. For this purpose, a lithotripsy probe combined with a Dormia basket was constructed. To date, this method has been successfully applied to break fragments off large calculi in three patients, without any complications arising. In one case, subsequent extraction of the remaining part of the stone was possible. The probe must, however, be improved to ensure that the stone is always held centrally in the basket.

Role of External Vibratory Lithoclast (Lithecbole) in Improving Lower Pole Stone Clearance After Extracorporeal Shock Wave Lithotripsy (ESWL).

<b>Background and Objective:</b> Extracorporeal shock wave lithotripsy (ESWL) is a widely used non-invasive treatment for renal stones. However, its effectiveness in clearing stones located in the lower pole of the kidney is often limited due to the anatomical challenges that impede the spontaneous passage of fragmented stones. This study evaluate the efficacy and safety of External Physical Vibration Lithecbole (EPVL) when used as an adjunctive therapy following ESWL in patients with lower pole renal stones, with a focus on improving stone clearance rates. <b>Materials and Methods:</b> This prospective interventional study was conducted at Al Yarmouk Teaching Hospital over two years and included 100 patients with 10-15 mm lower pole renal stones. Patients were randomized into two groups: The ESWL alone and ESWL plus EPVL. All patients received two ESWL sessions (3000 shocks/session). The treatment group additionally received EPVL therapy using a flank-applied vibration device. Follow-up was performed using ultrasound and KUB radiography. Statistical analysis was conducted using appropriate tests with significance set at p<0.05. <b>Results:</b> Baseline characteristics, including age, gender, weight, stone size and location, were statistically comparable between groups. The mean stone size was 12.4&#xb1;1.7 mm. A significantly higher stone-free rate was observed in the ESWL+EPVL group compared to the ESWL-only group (66% vs. 48%, p = 0.027). Although the residual stone size showed a numerical difference favoring EPVL, it was not statistically significant (p = 0.11). Complication rates were low, mild and similar in both groups (p = 0.3). Logistic regression analysis revealed that smaller stone size (p<0.001) and lower patient weight (p = 0.030) were significantly associated with successful stone clearance. Subgroup analysis further confirmed that patients with stones <11 mm or a weight <70 kg had the highest stone-free rates. <b>Conclusion:</b> In this initial evaluation, EPVL demonstrated a safe and effective adjunct to ESWL in enhancing stone clearance for lower-pole renal stones. Its application was associated with improved treatment outcomes without increasing complication rates. Further studies with extended EPVL sessions and longer follow-up are warranted.

Electrohydraulic lithotripsy: experimental study and case reports with the stone disintegrator.

Electrohydraulic lithotripsy with the SD-1 for crushing bladder stones was performed experimentally, in vitro and in vivo. The results of this experiment in laboratory animals and in 19 patients revealed that the procedure is safe and superior to the conventional methods with blind or optical lithotriptors. The methods is easy to learn and application of the technique may be combined in the same session with other urological operations. This procedure was done more than 50 times in toto without any complication.

Electrohydraulic impulse lithotripsy of bladder stones with URAT-I.

The electrohydraulic method of crushing bladder stones due to many aforesaid advantages can fully replace mechanical lithotripsy as being both more effective and having little danger of traumas. In rare cases when the stone cannot be crushed with Urat-I its removal should be performed by way of cystomy.

Temporal evolution of minimally invasive pediatric urolithiasis treatment over 30 years.

Urolithiasis in children has increased substantially over the past 30 years, and surgical management maintains an important role in treatment. Technological advances such as lasers and miniaturization have broadened treatment options, and researchers investigate the best indications for each procedure. The aim was to identify publication trends in the field and explore reasons why Extracorporeal Shockwave Lithotripsy is being gradually less applied in the treatment of pediatric urolithiasis. A Reverse Systematic Review of the literature was conducted regarding the surgical treatment of urolithiasis in children. Five databases were screened, gathering all articles from inception that were evaluated in systematic reviews. We examined 123 publications, 197 reports, and 15,878 procedures, consisting of the largest studied population in the field. There was an increasing number of publications, although in progressively less prestigious journals. The number of studies on miniaturized percutaneous techniques and flexible ureteroscopy has increased closely with the rise in popularity of these procedures worldwide, mainly driven by studies from Asia, Europe, and North America. A trend of self-renewed interest is fueled by technological innovation and has led to fewer publications on Extracorporeal Shockwave Lithotripsy over the years. This review highlights the fact that, despite positive results in recent studies, the low popularity of ESWL within the scientific community is driving a decline in the technique's indications. Moreover, based on the findings of this study, key research priorities include continued reporting of high-quality outcomes, and technological progress in ESWL would contribute meaningfully to the field.

Electrohydraulic cystolitholapaxy.

The electrohydraulic lithotrite generates high voltage discharges which, in a liquid medium, are converted to hydraulic shock waves capable of fracturing bladder stones. Electrohydraulic litholapaxy was successful in treating 28 of 30 patients with bladder stones. In nine patients other procedures were performed during the same anesthetic. In one patient, a calculus was removed from within a narrow-necked bladder diverticulum. Compared with conventional mechanical lithotripsy with serrated, jawed instruments, electrohydraulic lithotripsy is a safe, easy to learn and effective technique for treating bladder stones.

Factors associated with additional intervention requirement following ESWL in pediatric patients with urolithiasis.

OBJECTIVE: To identify predictors of additional intervention following extracorporeal shock wave lithotripsy (ESWL) in pediatric patients and to develop a clinically applicable predictive model. MATERIALS AND METHODS: This retrospective cohort study included 647 pediatric patients who underwent ESWL between 2015 and 2025. Demographic, clinical, and radiological variables were analyzed. Univariable and multivariable logistic regression analyses were performed to identify independent predictors of additional intervention. Model performance was evaluated using receiver operating characteristic curve analysis. RESULTS: Additional intervention was required in 65 patients (10.0%). On multivariable analysis, stone size 10-20 mm (OR: 3.04, p = 0.003), moderate (OR: 2.16, p = 0.049) and severe hydronephrosis (OR: 6.05, p < 0.001), and multiple stones (OR: 3.52, p = 0.030) were identified as independent risk factors. Increasing age (OR: 0.84, p = 0.026), history of urolithiasis (OR: 0.41, p = 0.006), and lower calyx location (OR: 0.14, p = 0.034) were associated with a reduced risk. The model demonstrated good discriminative performance (AUC: 0.794), with a sensitivity of 72% and specificity of 75%. Internal validation using bootstrap resampling demonstrated stable model performance, yielding a corrected AUC of 0.732. CONCLUSION: Stone burden, hydronephrosis severity, and stone multiplicity are key determinants of additional intervention after ESWL in pediatric patients. The proposed model shows good predictive performance and may support individualized risk stratification and clinical decision-making.

Advances in fragment removal devices in ureteroscopy: up-to-date review.

PURPOSE OF REVIEW: The development of laser lithotripsy for flexible ureteroscopy (fURS) has improved access and the ability to fragment renal stones. A common challenge for endourologists is managing the residual fragments (RF) of these stones. These RFs are associated with higher complication rates and the need for reinterventions and could serve as a focus for future stone formation. We aim to summarize recent technological advancements that increase the likelihood of removing more RFs and ultimately achieving stone-free status (SFS). RECENT FINDINGS: New technologies expand upon existing devices or create novel techniques, improving efficiency and increasing the volume of RF that can be extracted. Improvements to stone-grabbing baskets enable more controlled passes, reducing damage and complications. The flexible and navigable suction ureteric access sheath (FANS) builds on the traditional ureteral access sheath (UAS) by offering greater manoeuvrability and RF extraction from difficult anatomical locations. The development of urothelial-safe hydrogels provides an effective way to group and remove fragments. Additionally, magnetic hydrogels show promise for extracting tiny particles from hidden renal structures, advancing toward an ideal SFS. The Spinner-Induced Synergistic Circulation and Spiral Flow device also shows potential for rapidly removing numerous fragments. SUMMARY: Novel technological advancements build upon existing technologies or develop new methods of maximizing RF extraction while maintaining the balance of suction, irrigation, intrarenal pressure, and temperature - the Quadrifecta of retrograde intrarenal surgery (RIRS).

Epidemiology, diagnosis, and surgical management of urolithiasis in older adults: overview from EAU endourology.

PURPOSE OF REVIEW: Population ageing is changing everyday urological practice. The number of older adults is increasing, and urology already treats a patient population that is, on average, older than the general population. Consequently, older adults with urolithiasis represent a core part of contemporary endourological practice. Given this, a focused review of the available evidence is valuable to inform clinical practice. RECENT FINDINGS: A peak in stone disease can occur in older adults who may also be less likely to present with the classical features of renal colic. As such, delayed or missed diagnosis may carry greater clinical consequences. Although the literature remains relatively limited, ureteroscopy, shock wave lithotripsy, and percutaneous nephrolithotomy remain feasible options in appropriately selected older adults. In this group in particular, broader health associations merit consideration, as the presence of urolithiasis in older adults may reflect overall health status in later life. SUMMARY: The burden of urolithiasis in older adults is increasing and now represents a routine component of everyday clinical practice. Clinical presentation may differ from that seen in younger "index" patients, and complications may have a greater impact on recovery and function. Management should therefore be individualized, taking into account comorbidity, frailty, functional status, and the patient's own priorities.

Endoscopic procedures in the treatment of urologic disorders in children.

Cystoscopy has been a well established procedure in adult urology for years and more recently for the endoscopic evaluation of the lower urinary tract of infants and children. Utilizing small caliber cold light endoscopes and resectoscopes, therapeutic manipulations are readily possible. Among these are extraction of ureteral stones, lithotripsy of bladder calculi, transurethral resection of bladder tumors, as well as transurethral incision and resection of bladder-neck obstructions, urethral valves and urethral stenoses. The excellent results obtained in the treatment of infravesical urinary obstruction have contributed to the importance of transurethral surgery in pediatric urology.

[The effect of electrohydraulic waves and ultrasound on the urothelium].

An experimental study on 30 rabbit urinary bladders showed that the ultrasound lithotripsy causes less tissue damage and fewer complications than the use of electrohydraulic waves. The danger of perforation using electrolithotripsy is high whereas bladder wall perforations never were caused by ultrasound using the usual amplitudes and frequencies. An increase in temperature and edema formation in the bladder wall was caused by the ultrasound but this probably would be a minor damage in the clinical use.

Retrograde intrarenal surgery with flexible and navigable suction access sheaths vs mini-percutaneous nephrolithotomy for large upper urinary tract stones: a&#xa0;systematic review and meta-analysis.

OBJECTIVE: To conduct a meta-analysis comparing the efficacy and perioperative outcomes of contemporary flexible and navigable suction access sheath-assisted retrograde intrarenal surgery (FANS-RIRS) against percutaneous nephrolithotomy (PCNL) for the management of large upper urinary tract stones, as despite technological advances in RIRS such as high-powered lasers and FANS that have substantially enhanced its performance, current guidelines continue to recommend&#x2009;PCNL as first-line treatment for renal stones >2cm. METHODS: MEDLINE, Embase, and the Cochrane Library were searched for studies performing direct comparisons of FANS-RIRS against PCNL in adult patients until September 2025. Primary outcomes included stone-free rates (SFRs) and need for ancillary procedures. Secondary outcomes included operative time, length of postoperative hospitalisation, and postoperative complications. RESULTS: A total of 10 studies (three randomised control trials, seven retrospective cohort studies) comprising 2347 patients were included; preoperative stone sizes were predominantly 2-3&#x2009;cm. All PCNL procedures in the studies included were performed as mini-PCNL. The SFRs for FANS-RIRS were comparable with mini-PCNL across all stone sizes (odds ratio [OR] 0.90, 95% confidence interval [CI] 0.70-1.17) and stones &#x2265;2&#x2009;cm (OR 0.80, 95% CI 0.60-1.08), with low heterogeneity. Ancillary procedures rates were similar (OR 1.22, 95% CI 0.61-2.44). FANS-RIRS was associated with significantly fewer overall complications, specifically smaller haemoglobin decline, need for transfusion, and shorter hospital stay. However, mini-PCNL demonstrated shorter operative times for stones &#x2265;2&#x2009;cm. Urosepsis rates were low and similar between both groups. Limitations include predominance of Asian studies, variability of practice, and inclusion of non-randomised studies. CONCLUSIONS: Contemporary FANS-RIRS achieves SFRs comparable to mini-PCNL even for 2-3&#x2009;cm stones, while offering superior safety profiles and shorter hospitalisation; this supports FANS-RIRS as a viable primary treatment in selected patients.
