The case demonstrates the use of ureteroscopy with laser lithotripsy in the treatment of an obstructed left proximal ureteral stone with forniceal rupture. The patient presented to the emergency department with the signs and symptoms of a ureteral stone and was taken for imaging and a diagnostic ureteroscopy. Following confirmation of the diagnosis, the patient was scheduled for ureteroscopy with laser lithotripsy.

A guidewire was placed, followed by visualization with a retrograde pyelogram and a subsequent flexible ureteroscopy. Laser lithotripsy was performed to fragment the stone. Following fragmentation, the renal pelvis and calyces were visualized to examine for retrograde movement of stone fragments. A confirmatory retrograde pyelogram was then performed, followed by placement of a temporary stent for fluid drainage. The patient was then discharged with opioids for pain medication and prophylactic antibiotics to prevent urinary tract infections and the subsequent risk of urosepsis.

Otosclerosis can lead to progressive conductive hearing loss, significantly affecting quality of life. For patients who choose surgery, the tympanic membrane is elevated, and the middle ear space is explored. If the surgeon confirms that the stapes is fixed in the oval window, either a stapedotomy or stapedectomy can be performed.

In the stapedotomy, the surgeon removes the stapes superstructure, creates a fenestration in the footplate, and places a prosthesis from the incus through the fenestration into the vestibule. In this instance, the patient was able to regain nearly all of the hearing that had been lost as a result of stapes fixation.

The patient in this case is a 76-year-old male who was admitted to the ER two weeks prior and was found to have an obstructing, 1-cm left proximal ureteral stone with a forniceal rupture. A left ureteral stent was placed, and he was started on antibiotics. In this video, Dr. Ryan Hankins at MedStar Georgetown University Hospital performs definitive management of the stone with a left ureteroscopy, laser lithotripsy, and stent replacement.
