Ureteroscopy is a procedure in which a small flexible scope is inserted into the bladder and ureter and it is used to diagnose and treat a variety of problems in the urinary tract. For ureteral stones, it allows the urologist to actually look into the ureter, find the stone and remove it. The surgeon passes a tiny wire basket into the lower ureter via the bladder, grabs the stone and pulls the stone free. This is an outpatient procedure with or without a stent inserted. Ureteroscopy treatment can be used for virtually any kidney stone of a size appropriate for it. Fragmentation of stones using helium laser device ureteroscopy is more successful than with shock wave lithotripsy. Ureteroscopy is used for stones in the ureter, especially for stones closest to the bladder, in the lower half of the ureter. Ureteroscopy is divided into diagnostic endoscopy and therapeutic treatments. Diagnostic endoscopy minimizes mucosal distortion, allowing for complete mapping of the upper urinary tract. Therapeutic ureteroscopy is used in varied applications, including in the treatment of stones, urothelial tumours, and stricture disease. Ureteroscopy is a safe and minimally invasive method of treating stone disease in the kidneys and ureter as shown below. It can be used either as primary therapy or as salvage therapy for residual stones following treatment with other modalities. Most people are able to go home the same day of the procedure. But one may need to stay in the hospital for a maximum of 24 to 48 hours. For several hours after the procedure one may have a burning feeling when one urinates. This feeling should go away within a day. Drinking a lot of water can help reduce the burning.
