Modified pluck method in en bloc nephroureterectomy with bladder cuff for upper urothelial cancer.
OBJECTIVE
To evaluate the surgical results of the en bloc removal of the kidney and ureter with a bladder cuff by using our modified pluck method.


METHODS
We employed this procedure in 28 patients with renal pelvic and ureteral cancer. The clinical stages of the 28 patients were T(1-3)N(0-1)M(0). These patients were operated on by nephrectomy with standard open or retroperitoneoscopic surgery, and then standard or blind dissection of the distal ureter. After simultaneously making a transurethral circular incision of the ureteral meatus with a J-shaped electrode, the ureteral end was plucked out of the bladder, and en bloc removal of the kidney and ureter was performed from the wound.


RESULTS
The mean operating time for nephroureterectomy using the pluck method was 278 min in all cases. The mean time for the pluck procedure after nephrectomy was 24 min in 22 cases, and 73 min in six cases where the nephrectomy was carried out via a new lower pararectal wound. There were no intra- or postoperative complications associated with these procedures. Within the mean follow-up period of 25 months, there was no recurrence of tumors in the perivesical retroperitoneal space; however, the usual rate of intravesical recurrence was observed. Three patients died, two of metastatic urothelial cancer and one of heart disease.


CONCLUSIONS
En bloc nephroureterectomy using our modified pluck method is a useful procedure for patients with upper urothelial cancer because of the simplicity and ease of the procedure.
