In the top-right image, the cystoscope has been bent within the bladder to look back on itself. The bottom two images show an inflamed urethra. If a patient has a stone lodged higher in the urinary tract, the physician may use a much finer calibre scope called a ureteroscope through the bladder and up into the ureter. (The ureter is the tube ...
Ureteroscopy is an examination of the upper urinary tract, usually performed with a ureteroscope that is passed through the urethra and the bladder, and then directly into the ureter. [1] The procedure is useful in the diagnosis and treatment of disorders such as kidney stones and urothelial carcinoma of the upper urinary tract. [ 1 ]

The use of urinary catheters may cause a bladder stone. Individuals who are paralyzed or are unable to adequately pass urine may require the use of small plastic tubes placed into the bladder. The use of these tubes may lead to an infection, which irritates the bladder, resulting in stone formation. Finally, a kidney stone may travel down the ...
A technical drawback of ureteric stents is that they by-pass the 1-way valve at the entrance of the ureter into the bladder, the normal vesicoureteral (ureteral-bladder) junction. The function of this valve is to prevent backflow of urine from the bladder to the kidney ( vesicoureteral reflux ).

Urethral sounding is the practice of inserting objects (typically made by metal or silicone) into the urethra for sexual gratification. [1] Urethral dilatation is a urological procedure that uses probes called sounds to enlarge the inside diameter of the urethra and locate obstructions in the urethra, or as a treatment for urethral strictures.
The ureters are 1.5–6 mm (0.06–0.24 in) in diameter [1] and surrounded by a layer of smooth muscle for 1–2 cm (0.4–0.8 in) near their ends just before they enter the bladder. [2] The ureters enter the bladder from its back surface, traveling 1.5–2 cm (0.6–0.8 in) before opening into the bladder at an angle on its outer back surface ...
