Urinary tract after abdomino-perineal resection

Area of Science:

• Urology
• Radiology
• Surgical Oncology

Background:

• Abdomino-perineal resection (APR) is a complex surgical procedure for pelvic cancers.
• Post-operative complications can significantly impact patient outcomes and quality of life.

Purpose of the Study:

• To analyze uroradiological findings in patients following abdomino-perineal resection.
• To identify common complications and anatomical changes affecting the urinary tract after APR.

Main Methods:

• Retrospective analysis of uroradiological examinations.
• Involved 33 patients who underwent abdomino-perineal resection.
• Detailed assessment of ureteral position, bladder morphology, and presence of complications.

Main Results:

• Medial ureteral displacement was the most frequent finding, with right ureter crossing midline.
• All patients exhibited bladder deformity, ranging from mild to severe.
• 30% experienced localized ureteral narrowing (stricture/neoplasm); abscesses, fistulas, and retention were also noted, more in men.

Conclusions:

• APR significantly alters urinary tract anatomy, primarily ureteral position and bladder shape.
• Radiological monitoring is crucial for detecting complications like strictures and abscesses post-APR.
• Gender-specific differences in complication prevalence warrant further investigation.
