Laparoscopic Nephron-Sparing Calycectomy for Treating Fraley's Syndrome

Area of Science:

• Urology
• Minimally Invasive Surgery
• Nephrology

Background:

• Fraley's syndrome is a rare renal vascular anomaly causing upper calyceal obstruction.
• Symptoms include flank pain and hematuria.
• Nephron-sparing surgical techniques are described, but minimally invasive approaches are anecdotal.

Observation:

• A pure laparoscopic retroperitoneal approach was utilized for surgical correction.
• The procedure involved laparoscopic calycectomy without clamping of renal vascular branches.

Findings:

• Laparoscopic calycectomy without clamping renal branches completely avoids parenchymal ischemia.
• Preserving surrounding renal tissue maintains intrasinusal segmental artery flow.
• Hemostatic sutures did not cause accidental closure of arteries.

Implications:

• Laparoscopic nephron-sparing calycectomy is a safe and effective treatment for Fraley's syndrome.
• This technique preserves renal function and tissue.
• Requires significant laparoscopic surgical experience for successful implementation.
