  • Urinary conduit diversion

    An alternative method of redirecting urinary flow, known as urinary diversion or rerouting, involves the utilization of an intestinal segment as a conduit to guide urine towards an external collection pouch. This specialized technique employs a surgically created passage, using a segment of the intestine, to facilitate the directed drainage of urine. By establishing this…

  • Uretoscope

    A cylindrical instrument, introduced into the body through the urinary system, serves the dual purpose of visualizing and retrieving objects. This specialized device enables medical professionals to have a direct visual access and the ability to delicately grasp and remove foreign objects or obstructions within the urinary tract. Its tubular design facilitates precise maneuverability, ensuring…

  • Urethra hypermobility

    The primary contributing element to stress urinary incontinence, a condition characterized by the involuntary leakage of urine during physical exertion, is the descent of the urethra into the pelvic floor.

Serving as a crucial conduit, this tubular structure ensures the smooth and controlled elimination of urine, maintaining the body’s internal equilibrium.  

  • Ureterovesical valve

    A circular muscle-operated orifice positioned at the point where the ureter meets the bladder serves the crucial function of preventing the backward flow of urine towards the kidney. This sphincter, characterized by its ability to contract and relax, acts as a barrier, ensuring that urine remains directed towards its intended destination rather than reversing its…

  • Ureteral stent

    A medical apparatus surgically implanted in individuals with compromised ureters, designed to maintain the patency of the ureter and facilitate unhindered urine flow from the kidneys to the bladder.  

  • Urate crystals

    Solid structures formed due to elevated levels of uric acid in the bloodstream are known as uric acid crystals.  

  • Upper endoscopy

    A medical intervention involving the insertion of a slender, illuminated, flexible tube (endoscope) into the patient’s throat. Through this instrument, the physician gains visual access to the mucous lining of the esophagus, stomach, and the upper portion of the small intestine.  

  • Unresectable cancer

    A neoplasm that cannot be entirely excised through surgical intervention.  

  • Uniparental disomy
