Ureteroscopic lithotripsy of ureteric stone using thulium fiber laser in a pregnant patient, case report.

Nephrolithiasis represents a common cause of non-obstetrical abdominal pain during pregnancy with 1 out of 200 pregnancies being affected. 20%-30% of patients require ureteroscopy. Many studies were done on safety of holmium:yttrium-aluminium-garnet (YAG) during pregnancy but none on Thulium Fiber Laser (TFL). To our knowledge, this is the first reported case of pregnant patient with nephrolithiasis that was treated using ureteroscopy and TFL. We present a 28 years old pregnant woman that presented to our hospital with a left distal ureteric stone. Patient underwent URS and lithotripsy using TFL. The procedure was tolerated with no complications.
