“…Matsuura et al [26] compared SFRs between three groups of patients who were divided according to age (20)(21)(22)(23)(24)(25)(26)(27)(28)(29)(30)(31)(32)(33)(34)(35)(36)(37)(38)(39)(40)(41)(42)(43)(44)(45)(46)(47)(48)(49)(50)(51)(52)(53)(54)(55)(56)(57)(58)(59), and >70 years). The SFRs for proximal ureteral stones were independent of age-group (71.4, 83.3, and 83.3 % for the groups described above, respectively).…”

We investigated the effects of aging on the stone-free rate (SFR) after shock wave lithotripsy (SWL) for the treatment of proximal ureteral calculi. A total of 247 consecutive patients were retrospectively selected, classified into seven groups set at 10 year increments (from 20 to 90 years), and examined for SFR after SWL. According to our final analysis, 185 male and 62 female patients with an average age of 54.1 years had stones with a diameter of 11.5 mm and a density of 893.1 Hounsfield units. On average, SFR was 74.9 % at 3 months after 1.7 SWL sessions. SFR gradually reached ≥ 90 % for each age-group after 1.5-2 years. Median durations to achieve 50 % SFR were estimated to be 21 and 86 days for those in their 20 and 80 s, respectively. However, the difference between the two estimates was not significant (p = 0.064). The durations to achieve 50 % SFR for the other groups lay between these two estimates. Aging does not affect long-term SFR, but patients aged ≥ 80 years might experience delayed stone clearance within the first 12 months after SWL.

“…When these waves reencounter the stone-water interface, they generate more P and S waves which constructively overlap to generate high levels of stress in the stone, causing it to break down [53]. Cavitation bubbles also form in the surrounding fluid from the negative pressure components of the incident acoustic wave [53]. This process helps in breaking down the surface of the stone.…”

“…Shock Wave Lithotripsy: FUS waves can be used to break up kidney and ureter stones. The basic mechanism occurs when a strong US pulse hits a stone-water interface and generates longitudinal (P) and transverse (S) stress waves which propagate inside the stone [53]. When these waves reencounter the stone-water interface, they generate more P and S waves which constructively overlap to generate high levels of stress in the stone, causing it to break down [53].…”

Contrast agents have long helped researchers and physicians alike delineate boundaries, but new diagnostic information is always sought after. A new field of molecularly targeted CT agents hopes to fill this void and supply physicians with prognostic information to find better treatments for patients. Borrowing from drug delivery and design, nanoparticles and similar platforms are being explored to help visualize complex biologic processes with never before seen resolution and fidelity. We discuss the development of this field and feasibility of translating some of these prospects to the clinic. Advances in chemistry, molecular biology, and engineering have molded this field emphasizing the early detection and treatment of diseases at the molecular and cellular level. Myriads of nanomedicine platforms have been proposed and developed and tested in laboratories and in preclinical models. However, very few have been translated to clinical trials. It is therefore a critical issue to recognize the factors affecting their eventual application in human. Better understanding of biological and biophysical obstacles encountered by these agents is necessary. Toward this aim, we critically review our present understanding of the biological obstacles encountered by the nano-agents, which we hope will motivate more studies to tune these technologies for future translational and clinical applications.
