F-URS using a holmium laser is a very effective, minimally invasive technique. It could be the best option in managing stone-bearing caliceal diverticula, especially for those patients in whom there was SWL failure. The development of the actively deflectable ureteroscope with miniaturization allowed us to obtain a high success rate, low morbidity, and a brief hospital stay.

Emphysematous cystitis is a rare disease caused by gas-forming bacterial and fungal pathogens. It complicates urinary tract infections, especially in diabetic patients. Because clinical symptoms are not specific, the diagnosis is often made incidentally on radiography. We report the case of a 34-year-old woman who presented with fever, frequency, urgency and gross hematuria. CT scan of the pelvis revealed emphysematous cystitis which resolved after antibiotic treatment and bladder drainage.
