Modified "pluck" nephroureterectomy for upper urinary tract disorders: combined endourologic and open approach.

Abstract

Nephroureterectomy is the standard surgical approach for upper urinary tract transitional-cell carcinoma (TCC) and many other conditions. In 1952, a modification of the conventional method was described in which a transurethral resection of the ureteral meatus and intramural ureter is undertaken until the remaining ureter has no attachment to the bladder. The resected area and the distal tip of the ureter are coagulated, and the ureter is removed in continuity with the kidney through a single flank incision. Since January 1990, we have performed 12 nephroureterectomies with this technique (9 men and 3 women with an average age of 61.8 years, ranging from 35 to 73). Six of them were operated on for a TCC of the upper urinary tract, and the postoperative follow-up of these patients was from 6 to 54 months (mean 18.6). Within the follow-up period, tumor has not recurred either at the resected trigonal area or in the retroperitoneum, and only one patient has had a tumor distant from the site of ureteric resection. One patient with bladder TCC, who had a suspect kidney mass on the left side detected by CT, underwent nephroureterectomy with this technique. Five patients had primary renal disorders and upper tract calculous problems, in which nephroureterectomy was required. After the transurethral resection, an indwelling catheter was left in the bladder for 4 days. We believe that our experience confirms the feasibility of this technique in order to improve and simplify nephroureterectomy. Therefore, we recommend the modified "pluck" technique in all patients who are candidates for an operation requiring nephroureterectomy, as it gives considerable benefit to the patient.
