[Advantages of ilio-inguinal extraction of the kidney after retroperitoneoscopic nephroureterectomy].

INTRODUCTION: The manner to extract the specimen after retro-peritoneoscopic nephroureterectomy varies to different surgical teams. The aim of the surgeon is to extract the specimen with minimum parietal injuries, according with oncologic principles. The objective of our study was to evaluate the ilio-inguinal approach to extract the specimen after retro-peritoneoscopic nephroureterectomy.

MATERIAL AND METHOD: Evaluation and follow-up of 71 patients with retroperitoneoscopic nephroureterectomy for urothelial cancer (65 pelvic urothelial carcinoma and 6 urothelial carcinoma of the ureter). Ilio-inguinal incision was used for 68 patients to extract the specimen.

RESULTS: The operating time was 110 +/- 47 min. Blood lost 101 +/- 57 ml. Retroperitoneoscopic approach 10 +/- 4 min. Ilio-inguinal approach 25 +/- 10 min. The weight of the specimen was 601 +/- 127g. Tumor dimension was 5.9 +/- 1.9 cm. No conversion to open surgery was made. No late post surgery complications were registered ( follow-up at 2 and 6 months).

CONCLUSIONS: The enlarged nephroureterectomy can be performed using retroperitoneoscopic approach and the specimen can be extracted through an incision at iliac fossa. This approach can be used to extract large specimens preserving the esthetic laparoscopic benefit as well as the oncologic salty and reducing the risk of post-operative eventration.
