LITHIASIS ON FOREIGN BODIES
Figure 1. Lithiasis on suture thread in a 79-year-old man. A) and B) Lithiasis on suture thread. C) Fragment: 55% whewellite, 40% weddellite and 5% hydroxyapatite. D) Infrared spectrum (IRS) of organic matter. E) IRS corresponding to whewellite, weddellite, and hydroxyapatite.
The main cause of lithogenesis is supersaturation of some constituents in urine. Other factors as extreme pH, anatomical malformations or presence of promoters can facilitate this process too.
