left intramural ureter

The left intramural ureter is the terminal segment of the left ureter that passes through the wall of the urinary bladder. It is the section of the left ureter that travels within the bladder wall before opening into the bladder interior at the left ureteric orifice.

The left intramural ureter is located in the lower pelvis, embedded within the posterior wall of the urinary bladder on the left side. It connects the left distal ureter to the bladder interior, coursing obliquely through the bladder wall.

The left intramural ureter conducts urine from the left kidney into the urinary bladder. Importantly, its oblique course through the bladder wall creates a valve-like mechanism that helps prevent backflow (reflux) of urine from the bladder into the left ureter when bladder pressure increases.

Conditions involving the intramural ureter may include vesicoureteral reflux, ureteral obstruction, or abnormalities at the ureterovesical junction. These are evaluated by healthcare professionals through appropriate imaging and clinical assessment.

The left intramural ureter may be evaluated with imaging studies such as CT urography, intravenous pyelography, or ultrasound. Cystoscopy allows direct visualization of the ureteric orifice, and voiding cystourethrography may be used to assess reflux.
