Abstract: | OBJECTIVES: To describe a purely laparoscopic nephroureterectomy approach that avoids the disadvantages of transurethral bladder cuff excision and open/laparoscopic distal ureterectomy using the EndoGIA. METHODS: A standard transperitoneal laparoscopic nephrectomy is carried out through three or four ports in the flank. The ureter is dissected caudally into the pelvis. Two additional (5- and 10-mm) trocars are placed in the ipsilateral lower abdomen. Caudal ureteral dissection continues until the detrusor muscle fibers at the ureterovesical junction are identified. A 1-cm area of bladder adventitia around the ureterovesical junction is cleared. The ureter is retracted upward and laterally, tenting up the bladder wall. The bladder cuff is excised using a 10-mm LigaSure Atlas and detached from the bladder. A 6-cm lower-quadrant incision is used to remove the specimen in an Endocatch bag. An indwelling 16F Foley catheter is then placed. RESULTS: Thirteen adult patients with suspected upper-tract transitional cell carcinoma underwent this surgical technique (operative time: 170-270 min): none had local recurrence, and two had recurrence remote from the bladder cuff scar (follow-up: 1-23 months). CONCLUSIONS: The described procedure adheres strictly to oncologic principles (removal of the affected renal unit without opening the urinary tract), and circumvents the need for transurethral/intraureteral instrumentation and patient repositioning. |
