Urinary stones Ureteroscopy Objective: the intervention proposed to you is intended to: - process a calculation - treat a tumor - treat another condition - carry out a diagnostic exploration Some notions of anatomy of the urian system The diagram below will help you locate the different parts of the urinary system. This will allow you to better understand the explanations of your surgeon who indicated this treatment. In your abdomen (tummy) is the entire system for making and storing urine and the passages for its evacuation. The diagram opposite will help you locate the different parts of the urinary system. The kidneys (R) are located at the top and back of the abdomen. There is usually one kidney on the right and one on the left. The kidney is about 12 cm high and contains cavities (calyxes) to collect urine. These calyxes come together to form the renal pelvis (B). From there a thin channel leads the urine from the kidney to the bladder (V): this is the ureter (U). It measures approximately 20 cm in length. The two ureters (right and left) carry urine to the bladder. The bladder is the reservoir for urine. Urine leaves the bladder (urination) through a channel called the urethra. Ureteroscopy provides access to the ureter and renal cavities for diagnostic or therapeutic purposes.

Disease Urinary stones affect approximately 10% of the adult population. In some cases they can be eliminated spontaneously and do not require any treatment. However, they can also be complicated by pain, infections and in some cases can affect kidney function. Intervention is then necessary. Tumors of the renal cavities and ureter are very rare. They can be revealed by bleeding in the urine but can also be diagnosed incidentally. They most often justify treatment in a urological environment. Other benign or malignant affections can reach the renal cavities and the ureter. The diagnosis and treatment of these conditions can also be done by ureteroscopy. Support options at this point Kidney stones and ureter stones can be treated in a variety of ways. Extracorporeal lithotripsy is one of the most widely used treatments. Nevertheless, some calculations, by their size, their location, their symptomatic nature or the risks they pose to your health may justify treatment by natural means called ureteroscopy. Tumors of the renal cavities and the ureter can be the subject of different treatments by endoscopic or surgical way. The progressive risks may justify the performance of a ureteroscopy. Certain affections of the renal cavities and the ureter can also be treated by endoscopic means.

Principle of the intervention The intervention consists of introducing a device called a ureteroscope into the ureter. This optical instrument measures approximately 3 mm in diameter and allows work under visual control. It contains a working channel through which various instruments are introduced. Some ureteroscopes are metallic and rigid, others are flexible. The choice of the instrument will be made by the urologist according to different parameters.
