Abstract

OBJECTIVE

To report our experience in applying the Lich-Gregoir extravesical ureteral reimplantation (EVR) approach to complex cases (megaureter, duplex systems) through a small inguinal incision, with the goal of minimizing invasiveness.

MATERIALS AND METHODS

We reviewed the records of all patients who underwent common sheath or tapered EVR through an inguinal incision. Patient characteristics and reflux grade were obtained, and outcomes were assessed. The technique involved a 2-cm incision made in the lowest inguinal skin crease, standard cord exposure and lateral retraction, and opening the floor of the canal to isolate the ureter. Excisional tapering was performed with the ureter dismembered from the bladder and then reimplanted via detrusorrhaphy, whereas common sheath reimplantation was performed with advancement fixation sutures and the ureters in situ.

RESULTS

Twenty-eight patients (15 males and 13 females) with a median age of 1.7 years (range: 0.9-4.8 years) were included. Fifteen patients had ureteral tapering, 12 underwent common sheath reimplantation, and 1 child had both. Success was seen in 94% for tapering and 92% for common sheath reimplants, with a mean follow-up of 29.6 months. There were no postoperative obstructions, urinary leaks, or wound infections.

CONCLUSION

The inguinal approach can safely and effectively be applied to cases of extravesical ureteral tapering and common sheath reimplantation.
