Lymphatic sparing microscopic retroperitoneal varicocelectomy: a preliminary experience.

Area of Science:

• Urology
• Pediatric Surgery
• Surgical Techniques

Background:

• The Palomo technique is a common approach for adolescent varicocele.
• The standard Palomo technique carries a risk of hydrocele formation.
• Microscopic inguinal and subinguinal surgeries have lower hydrocele rates but can be lengthy.

Purpose of the Study:

• To report the experience of a single surgeon using a modified Palomo technique for adolescent varicocele.
• To assess the efficacy of preserving lymphatics during retroperitoneal varicocelectomy using an operating microscope.
• To reduce the incidence of postoperative hydrocele compared to the traditional Palomo technique.

Main Methods:

• A total of 20 boys with grade III varicocele underwent retroperitoneal gonadal vessel ligation.
• An operating microscope was used to identify and spare lymphatic vessels during the procedure.
• Patients were followed for a mean of 11.2 months to assess outcomes.

Main Results:

• Microscopic retroperitoneal varicocelectomy with lymphatic sparing was successfully performed in all patients.
• No instances of hydrocele or varicocele recurrence were observed during follow-up.
• The operative time was shorter than traditional microscopic inguinal approaches.

Conclusions:

• The modified Palomo technique, incorporating microscopic lymphatic sparing in the retroperitoneum, is effective for adolescent varicocele.
• This approach combines the simplicity of the Palomo technique with reduced hydrocele rates.
• The technique offers high success rates with no reported complications in this series.
