Patient selection before endopyelotomy: can it improve the outcome?

Area of Science:

• Urology
• Surgical Innovation
• Medical Imaging

Background:

• Pelvi-ureteric junction (PUJ) obstruction is a condition that can impair kidney function.
• Endopyelotomy and reconstructive surgery are common treatments for PUJ obstruction.
• Identifying patients at risk for endopyelotomy failure is crucial for optimizing treatment outcomes.

Purpose of the Study:

• To compare the effectiveness of endopyelotomy and primary reconstructive procedures in patients with PUJ obstruction.
• To evaluate the role of endoluminal ultrasonography (US) in identifying risk factors for endopyelotomy failure.
• To determine if pre-treatment US guidance can improve patient selection and surgical outcomes.

Main Methods:

• Nineteen patients with PUJ obstruction underwent pre-treatment endoluminal US.
• US findings, including crossing vessels and degree of hydronephrosis, guided treatment decisions.
• Patients were divided into two groups: Group 1 (reconstructive surgery based on US findings) and Group 2 (endopyelotomy without pre-treatment US guidance).

Main Results:

• Endoluminal US identified crossing vessels in 13 of 19 patients, altering treatment plans for nine.
• Endopyelotomy success rate was 12/13 in Group 1 (with US guidance) compared to 8/12 in Group 2 (without US guidance).
• Reconstructive surgery was successful in 5/6 patients.

Conclusions:

• Endoluminal US is a valuable tool for selecting patients who are unlikely to succeed with endopyelotomy.
• Utilizing reconstructive procedures for high-risk patients identified by endoluminal US may enhance overall treatment success rates for PUJ obstruction.
• Further investigation in larger cohorts is warranted to confirm these preliminary findings.
