[Endoscopic recanalization in treating ureteral obliteration]

Area of Science:

• Urology
• Medical Imaging

Background:

• Urethral obliteration presents diagnostic and therapeutic challenges.
• Accurate assessment of urethral defects and surrounding structures is crucial for effective treatment.

Purpose of the Study:

• To evaluate a comprehensive diagnostic approach for urethral obliteration.
• To assess the efficacy and safety of endoscopic urethral recanalization for treating urethral obliteration.

Main Methods:

• Developed a complex examination method including X-ray, ultrasound, and NMR tomography.
• Performed endoscopic urethral recanalization on 86 patients aged 7-78.
• Utilized repeated internal optic urethrotomy and chronic urethral bouginage for rehabilitation.

Main Results:

• The complex examination provided significant information on urethral defects and adjacent tissues.
• Endoscopic urethral recanalization achieved good or satisfactory results in 93.02% of patients.
• Secondary urethral stricture occurred in 41.86% of patients, with 94.4% stabilized after further treatment.
• Serious intraoperative complications occurred in 3.49% of patients, including rectal perforation, TUR syndrome, and a fatal outcome due to hemorrhage and myocardial infarction.

Conclusions:

• The developed complex examination method enhances diagnostic accuracy for urethral obliteration.
• Endoscopic urethral recanalization is a viable treatment option with a high success rate, but requires vigilant management of potential complications and secondary strictures.
• Careful technique and patient selection are vital to minimize intraoperative risks.
