indigo-carmine and Uterine-Prolapse

Many gynecologic, urologic, and pelvic reconstructive surgeries require accurate intraoperative evaluation of ureteral patency.. We performed a randomized controlled trial to compare surgeon satisfaction with 4 methods of evaluating ureteral patency during cystoscopy at the time of benign gynecologic or pelvic reconstructive surgery: oral phenazopyridine, intravenous sodium fluorescein, mannitol bladder distention, and normal saline bladder distention.. We conducted an unblinded randomized controlled trial of the method used to evaluate ureteral patency during cystoscopy at time of benign gynecologic or pelvic reconstructive surgery. Subjects were randomized to receive 200 mg oral phenazopyridine, 25 mg intravenous sodium fluorescein, mannitol bladder distention, or normal saline bladder distention during cystoscopy. The primary outcome was surgeon satisfaction with the method, assessed via a 100-mm visual analog scale with 0 indicating strong agreement and 100 indicating strong disagreement with the statement. Secondary outcomes included comparing visual analog scale responses about ease of each method and visualization of ureteral jets, bladder mucosa and urethra, and operative information, including time to surgeon confidence in the ureteral jets. Adverse events were evaluated for at least 6 weeks after the surgical procedure, and through the end of the study. All statistical analyses were based on the intent-to-treat principle, and comparisons were 2-tailed.. In all, 130 subjects were randomized to phenazopyridine (n = 33), sodium fluorescein (n = 32), mannitol (n = 32), or normal saline (n = 33). At randomization, patient characteristics were similar across groups. With regard to the primary outcome, mannitol was the method that physicians found most satisfactory on a visual analog scale. The median (range) scores for physicians assessing ureteral patency were 48 (0-83), 20 (0-82), 0 (0-44), and 23 (3-96) mm for phenazopyridine, sodium fluorescein, mannitol, and normal saline, respectively (P < .001). Surgery length, cystoscopy length, and time to surgeon confidence in visualization of ureteral jets were not different across the 4 randomized groups. During the 189-day follow-up, no differences in adverse events were seen among the groups, including urinary tract infections.. The use of mannitol during cystoscopy to assess ureteral patency provided surgeons with the most overall satisfaction, ease of use, and superior visualization without affecting surgery or cystoscopy times. There were no differences in adverse events, including incidence of urinary tract infections.

The objective of the study was to determine the incidence of ureteral obstruction during vaginal surgery for pelvic organ prolapse and the accuracy and efficacy of intraoperative cystoscopy.. The study was a retrospective review of 700 consecutive patients who underwent vaginal surgery for anterior and/or apical pelvic organ prolapse with universal intraoperative cystoscopy.. Thirty-seven patients (5.3%) had no spillage of dye from 1 or both ureters intraoperatively. The false-positive and negative cystoscopy rates were 0.4% and 0.3%, respectively. Thus, the true incidence of intraoperative ureteral obstruction was 5.1%. Intraoperative cystoscopy was accurate in 99.3% of cases, with a sensitivity and specificity of 94.4% and 99.5%, respectively. Suture removal relieved ureteral obstruction in 88% of cases. Six subjects (0.9%) had true ureteral injuries.. Vaginal surgery for anterior and/or apical pelvic organ prolapse is associated with an intraoperative ureteral obstruction rate of 5.1%. Intraoperative cystoscopy accurately detects ureteral obstruction and allows for relief of obstruction in the majority of cases.

Unrecognized ureteral and bladder injury are a known source of morbidity and mortality in gynecologic surgery. The objective of this study was to determine the frequency that intraoperative cystoscopy during prolapse and incontinence procedures produced a change in intraoperative management to prevent ureteric and bladder injury.. This study reviewed the charts and operative reports of 235 cases of routine intraoperative cystoscopy during prolapse and incontinence surgery during a 2-year period in a tertiary care urogynecology unit. Demographic data and potential risk factors for intraoperative urinary tract injury were recorded. Cases that involved a change in management brought about by intraoperative cystoscopy with intravenous indigo carmine were compared with cases in which intraoperative cystoscopy was normal. Variables were compared with use of the Student t test and the chi(2) test.. Of 235 cases, 11 were excluded. Of the 224 remaining cases, 12 (5.3%) underwent changes in intraoperative management as a result of cystoscopic findings. Eight cases involved ureteric blockage. Patients with abnormal cystoscopies did not differ from patients with normal intraoperative findings with regard to age, weight, parity, maximum grade of prolapse, estimated blood loss, or previous surgery. In 58% of patients with abnormal cystoscopies, there was no suspicion of technical difficulty on the basis of previous surgical history. Preoperative renal imaging did not predict cases with abnormal cystoscopy. There were no cases of complications caused by the intraoperative cystoscopy.. Intraoperative cystoscopy with intravenous injection of indigo carmine is a safe technique that can detect otherwise undetected intraoperative compromise of the urinary tract during prolapse and incontinence surgery. It is recommended that cystoscopy be used liberally to reduced the frequency of serious sequelae from urinary tract injury.
