[Functional ability of the ileo-ureter determined by camera function scintigraphy]

Area of Science:

• Veterinary Medicine
• Surgical Techniques
• Diagnostic Imaging

Background:

• Investigating the functional outcomes of surgical interventions on the urinary system is crucial for improving patient care.
• Evaluating different surgical techniques for ureteric reconstruction requires reliable functional assessment methods.

Purpose of the Study:

• To assess the functional performance of the ileo-ureter and operated kidney in dogs following various surgical techniques.
• To compare the efficacy of different ureteroileal anastomosis methods using functional scintigraphy.

Main Methods:

• Functional scintigraphy was employed in 23 dogs using two radiopharmaceuticals: iodine-131-labeled iodohippuran (131I-Hippuran) and technetium-99m-labeled diethylenetriamine penta-acetate (99mTc-DTPA).
• A gamma camera microprocessor system was utilized for non-invasive imaging and data acquisition.
• Surgical techniques varied among the canine subjects, allowing for comparative functional analysis.

Main Results:

• The direct single-layered ileo-ureteric anastomosis technique exhibited the most effective urine transportation.
• Camera functional scintigraphy provided valuable insights into the functional status of the operated kidney and the ileo-ureter.
• Differential assessment of radiopharmaceutical clearance indicated varying degrees of functional success among surgical groups.

Conclusions:

• The direct single-layered ileo-ureteric anastomosis is recommended for optimal urine transport in canine urinary reconstruction.
• Camera functional scintigraphy is a valuable non-invasive tool for evaluating the function of ureteroileal conduits and operated kidneys.
• This surgical approach holds significant practical importance for veterinary surgical procedures.
