Background/Purpose:
The technical and ergonomic details of laparoendoscopic single site (LESS) reconstruction have not been reported. In this study, we explored the feasibility and safety of performing advanced LESS upper urinary tract reconstruction with conventional laparoscopic instruments.
Methods:
Between September 2010 and March 2011, we retrospectively reviewed prospectively collected data from five patients who underwent LESS urinary tract reconstruction. The LESS reconstruction included pyeloureterostomy (N = 1), dismembered pyeloplasty (N = 2), ureteroneocystostomy (N = 1), and ureteroplasty for bifid blind ending ureter (N = 1). The perioperative and postoperative parameters were collected for analysis. The ergonomic principles and techniques are detailed.
Results:
All reconstructive LESS procedures were completed successfully without open conversion or laparoscopic conversion. Ancillary ports or ancillary instruments were not applied in any of the patients. The mean patient age was 40.4 years. The mean operative time was 213 ± 69 minutes, the estimated blood loss ranged from minimal to 50 mL, and the mean hospital stay was 4.4 ± 4 days. No operation-related complication occurred.
Conclusion:
Based on our ergonomic principles and suturing/knotting techniques, conventional laparoscopic instruments are feasible and safe for LESS urinary reconstructive procedures.
