“…A previous study demonstrated morphologic changes of the mucosa in the stone bed after 48 hours, such as a marked increase in hyperplasia and mitotic activity in histologic examinations [18]. This gradual increase in ureteral mucosal oedema prevents luminal distension and the formation of uid interfaces, impeding adequate delivery of shock wave energy, which decreases fragmentation and expulsion of stones [19]. Furthermore, Cummins et al [20] showed that the duration after symptom onset was the most important predictor of ureteral stone removal.…”

“…6). This can be explained by the above pathophysiological principles that oedema and hyperplasia of the ureteral mucosa due to stone obstruction limit the luminal distension and formation of uid interfaces [19]. This not only reduces the fragmentation rate after ESWL but also compromises stone clearance, simultaneously increasing the sessions of ESWL and the need for ureteroscopic lithotripsy.…”

Objective To compare the clinical efficiency and safety of emergency extracorporeal shock wave lithotripsy (eESWL) and delayed extracorporeal shock wave lithotripsy (dESWL) in the treatment of ureteral stones. Methods Cochrane Library, PubMed, Google Scholar, and Web of Science were searched from inception to September 30, 2022, and all comparative studies involving eESWL and dESWL for ureteral calculi were included. Statistical analysis was performed using Review Manager 5.3 software. Results A total of 9 articles involving 976 patients diagnosed with ureteral stones were included. The results showed that the stone-free rate (SFR) after four weeks was significantly higher in the eESWL group than in the dESWL group [odds ratio (OR) = 2.19, 95% confidence interval (CI): 1.62–2.96, P < 0.01]. In subgroup analysis of different stone locations, proximal ureteral calculi [OR = 2.37, 95% CI: 1.66–3.38, P < 0.01] and mid-to-distal ureteral calculi [OR = 2.47, 95% CI: 1.23–4.97, P < 0.05] all showed a higher SFR in the eESWL group. eESWL significantly shortened the stone-free time(SFT) [mean difference (MD) = -5.75, 95% CI: -9.33 to -2.17, P < 0.01]. In addition, eESWL significantly reduced auxiliary procedures [OR = 0.45, 95% CI: 0.32–0.64, P < 0.01]. No significant difference in complications was found between the two groups [OR = 0.84, 95% CI: 0.56–1.27, P > 0.05]. Conclusion eESWL can significantly improve SFR, shorten SFT, and reduce auxiliary procedures.

“…5 Although the treatment with ESWL showed the variation in the stone-free rate between 50-70%, 70-90% and 50-90% respectively. 6 However, a number of variables, including stone size, content, pelvicalyceal anatomy, and others, affect the success rate of ESWL 7 . Additionally, there are issues with numerous sessions, in complete stone clearance, the necessity for additional operations, and complications following ESWL.…”

Aim: To provide a specific guidance in managing renal stones. Study Design: Place and Duration of Study: Pakistan Atomic Energy Commission, General Hospital Islamabad from 1st 2018 to 30th November 2018. Methodology: Eighty two patients were included and divided into two groups. Patients in group A underwent ESWL, while those in group B underwent PCNL. All of the participants underwent thorough diagnostic and therapeutic procedures. As per inclusion and exclusion criteria, patients with renal stones (10-20 mm), detected by CT scan were selected for either ESWL or PCNL. Results: Thirty four patients in the PCNL group and 21 patients in the ESWL group, had post-operative hematuria at the time of presentation (p=0.072). There is a substantial difference between patients between 18-38 years and those in the 60+ years. According to the stone-free rate, 76 individuals had favourable results whereas only 6 had negative ones (p=0.756 and p=0.050). Conclusion: Extracorporeal shockwave lithotripsy and pecutaneous nepthrolithotripsy are both effective technique options for kidney stones. However, since ESWL is non-invasive and has fewer adverse effects than PCNL treatment option, it is more successful in treating medium-sized kidney stones (20 mm or smaller).

“…Despite clinical CT techniques that currently approach 1 mm resolution, patients with SWL-derived residual stone particles that are ≤ 3–4 mm in diameter are considered to be “clinically insignificant residual fragments” because they are assumed to be able to spontaneously pass. Therefore, patients with fragments up to this size are classified as being in a “stone free state” and considered to not require further treatment 15 – 18 , 25 . In contrast, post-SWL treatment patients also commonly experience high stone recurrence rates that reach ~ 78% 26 , 27 , which may at least partially result from crystallization at sites of SWL-induced tissue damage as observed in renal histology section 28 .…”

GeoBioMed perspectives on kidney stone recurrence from the reactive surface area of SWL-derived particles

Shock wave lithotripsy (SWL) is an effective and commonly applied clinical treatment for human kidney stones. Yet the success of SWL is counterbalanced by the risk of retained fragments causing recurrent stone formation, which may require retreatment. This study has applied GeoBioMed experimental and analytical approaches to determine the size frequency distribution, fracture patterns, and reactive surface area of SWL-derived particles within the context of their original crystal growth structure (crystalline architecture) as revealed by confocal autofluorescence (CAF) and super-resolution autofluorescence (SRAF) microscopy. Multiple calcium oxalate (CaOx) stones were removed from a Mayo Clinic patient using standard percutaneous nephrolithotomy (PCNL) and shock pulse lithotripsy (SPL). This produced approximately 4–12 mm-diameter PCNL-derived fragments that were experimentally treated ex vivo with SWL to form hundreds of smaller particles. Fractures propagated through the crystalline architecture of PCNL-derived fragments in a variety of geometric orientations to form rectangular, pointed, concentrically spalled, and irregular SWL-derived particles. Size frequency distributions ranged from fine silt (4–8 μm) to very fine pebbles (2–4 mm), according to the Wentworth grain size scale, with a mean size of fine sand (125–250 μm). Importantly, these SWL-derived particles are smaller than the 3–4 mm-diameter detection limit of clinical computed tomography (CT) techniques and can be retained on internal kidney membrane surfaces. This creates clinically undetectable crystallization seed points with extremely high reactive surface areas, which dramatically enhance the multiple events of crystallization and dissolution (diagenetic phase transitions) that may lead to the high rates of CaOx kidney stone recurrence after SWL treatment.
