Transmesenteric approach for left transperitoneal renal surgery: technique and experience

Area of Science:

• Urology
• Minimally Invasive Surgery
• Surgical Techniques

Background:

• Laparoscopic surgery is the standard for treating various urological conditions like renal cancer and ureteropelvic junction obstruction (UPJO).
• A transmesenteric approach minimizes bowel manipulation during left laparoscopic pyeloplasty, reducing potential complications.
• This technique is being explored for other left renal procedures.

Purpose of the Study:

• To detail the surgical technique of the transmesenteric approach for laparoscopic pyeloplasty, pyelolithotomy, and simple nephrectomy.
• To evaluate the advantages and outcomes of this approach in clinical practice.

Main Methods:

• A retrospective review of 12 laparoscopic procedures using a transmesenteric approach for left renal diseases.
• Procedures included treatment for left UPJO (9 cases), left pelvic-ureteral stones (2 cases), and left end-stage kidney disease (1 case).
• Data collected from December 2007 to May 2010.

Main Results:

• All 12 procedures were completed laparoscopically without conversion to open surgery.
• No intraoperative complications or need for blood transfusions were reported.
• Patients experienced rapid recovery, with oral intake and bowel function resuming within 48 hours post-procedure.
• All patients had an uneventful postoperative course.

Conclusions:

• The transmesenteric approach is a valuable technical advancement in minimally invasive urological surgery.
• It offers advantages for treating left renal diseases, demonstrating safety and efficacy.
• This technique provides a beneficial alternative for laparoscopic pyeloplasty, pyelolithotomy, and nephrectomy.
