title: Cystoscopic temporary ureteral catheterization during radical vaginal and abdominal trachelectomy.
abstract: OBJECTIVE
  To describe the role of temporary retrograde ureteral catheterization at the time of fertility-sparing radical vaginal or abdominal trachelectomy in women with early-stage cervical cancer.
  
  
  METHODS
  We analyzed a prospectively maintained database of all patients with cervical cancer who were explored for radical vaginal or abdominal trachelectomy at our institution. Cystourethroscopy and ureteral catheterization were performed prior to the vaginal or abdominal operation in all patients, except two pediatric ones. Temporary bilateral retrograde ureteral catheters were planned for all patients as part of our routine procedure to facilitate identification of the distal ureters. 5Fr whistle-tip or open-ended catheters were used and usually advanced to approximately 20 cm. Catheters were removed at the end of the operation in all cases. All catheters were inserted by a gynecologic oncology fellow or attending.
  
  
  RESULTS
  Between 11/01 and 12/05, 40 patients were taken to the operating room for planned fertility-sparing radical vaginal or abdominal trachelectomy. We previously reported on two pediatric patients; they are excluded from this report. The median age for adult patients was 32 years (mean, 31.6; range, 23-40). International Federation of Gynecology and Obstetrics (FIGO) stage included IB1 (26), IA2 (6), and IA1 with lymphovascular invasion (6). Thirty-four patients underwent radical vaginal trachelectomy and four underwent a radical abdominal trachelectomy. Two (5%) of 38 patients required immediate completion radical hysterectomy due to extensive endocervical disease (one in the vaginal group and one in the abdominal group). Bilateral ureteral catheters were inserted successfully in 37 (97%) of 38 patients and facilitated identification of the distal ureter during the dissection. In one case, the right ureteral orifice could not be successfully catheterized, and the case was completed with unilateral catheterization. The estimated time to perform this part of the operation was approximately 15-20 min. Twenty-eight patients (74%) had 5Fr whistle-tip ureteral catheters inserted, and 10 had open-ended catheters inserted. There were no intraoperative complications. Median hospital stay was 3 days (range, 3-7). Hematuria, evident in the drainage bag attached to the Foley catheter, usually resolved in 24-48 h. Two (20%) of 10 patients who had open-ended catheters inserted developed a transient rise in postoperative creatinine (1.7 and 3.5 mg/dl, respectively) compared to 0/28 patients who had whistle-tip catheters placed (P<0.001). Both were attributed to postoperative distal ureteral edema, and only one patient required reinsertion of temporary ureteral stents. No patient developed long-term urinary complications or fistulae.
  
  
  CONCLUSIONS
  Cystourethroscopy and bilateral retrograde ureteral catheterization by gynecologic oncologists is a simple and quick procedure that may facilitate identifying the distal ureter during radical vaginal or abdominal trachelectomy. We favor using 5Fr whistle-tip catheters as they may be associated with less ureteral mucosal trauma and subsequent postoperative edema. The skills needed for this procedure should be available to fellows in gynecologic oncology training.
