A novel technique for management of the en bloc bladder cuff and distal ureter during laparoscopic nephroureterectomy.
Journal of Urology 1999 Februrary
PURPOSE: The optimal technique of excising the juxtavesical ureter and bladder cuff during laparoscopic nephroureterectomy is still evolving. We report on a novel transvesical needlescopic (2 mm. instrumentation) assisted technique of en bloc retrieval of the juxtavesical ureter and bladder cuff during laparoscopic radical nephroureterectomy for upper tract transitional cell carcinoma.
MATERIALS AND METHODS: Retroperitoneal laparoscopic nephroureterectomy was performed in 8 patients using this technique. Two needlescopic ports (2 mm.) inserted suprapubically into the bladder were used in combination with a cystoscopically positioned Collins knife.
RESULTS: Satisfactory circumferential detachment of the bladder cuff and en bloc mobilization of 3 to 4 cm. of the intact pelvic extravesical ureter were achieved transvesically in each case in a manner comparable to open surgery.
CONCLUSIONS: This technique simulates established open surgical principles of treating the distal ureter during laparoscopic nephroureterectomy.
