Internal ureteral stents significantly dilate ureters and cause low-pressure vesicoureteral reflux in canines. However, these stents do not impact renal function or alter serum chemistry.

Area of Science:

  • Urology
  • Nephrology
  • Comparative Medicine

Background:

  • Internal ureteral stenting is a common procedure.
  • Understanding the associated anatomical and functional changes is crucial.

Purpose of the Study:

  • To evaluate the anatomic, hydrodynamic, functional, and pathologic changes following unilateral internal ureteral stenting in female canines.
  • To assess the impact on renal function, vesicoureteral reflux, and ureteral morphology.

Main Methods:

  • Selective glomerular filtration rates (GFR) measured using technetium 99m diethylenetriamine pentaacetic acid (DTPA) renal scans.
  • Cystometry and cystography performed to assess vesicoureteral reflux and intravesical pressure.
  • Comparison of ureteral lumenal capacities between stented and unstented ureters.

Main Results:

  • Ureteral lumenal volumes were threefold greater in stented ureters (p < 0.002).
  • Low-pressure vesicoureteral reflux occurred in 84.6% of canines.
  • No significant differences in selective GFR or serum chemistries were observed.
  • Ineffective ureteral peristalsis was noted on fluoroscopic imaging.

Conclusions:

  • Internal ureteral stents cause significant ureteral dilation and vesicoureteral reflux.
  • Renal function, as measured by GFR, remains unaltered by stenting.
  • Stenting impacts ureteral hydrodynamics and function without systemic effects.
