Objective To study the sensitivity and specifity for detection of bladder tumor by Narrow-band imaging flexible cystoscopy compared with WLI flexible systoscopy. Methods Between February 2009 and July 2009, NBI flexible cystoscopy and conventional WLI flexible cystoscopy with the same instrument (Olympus Exera Ⅱ endoscopy system) were both performed on 31 patients highly suspect of bladder neoplasm with same observed time and in a randomized sequenced paradigm. Every suspect mucosa lesion was biopsied in both NBI and WLI image to compare the diagnostic accuracy between them. Results Twenty-eight patients(90%) were pathologically bladder urothelial cell carcinoma (UCC). Of 28 patients 3 were Tis, 15 were Ta, 7 were T1, and 3 were T2. Twenty were low grade carcinom, 8 were high grade carcinoma and 16 had multiple tumors, 12 had a single tumor.Of 73 biopsied lesions, 61 were diagnosed UCC under WLI image with 84% sensitivity, while 80 of 91 diagnosed under NBI image with 88% sensitivity. WLI detected 23 patients with bladder UCC while NBI detected all 28 patients. NBI detected 19 additional UCC lesions in 15 of 28 patients, as compared with WLI(P<0. 05). Conclusion NBI flexible cystoscopy can detect more bladder urothelial cell carcinoma than WLI flexible cystoscopy. 相似文献

ObjectiveThis is a prospective trial comparing the impact of intraoperative flexible, rigid, and no cystoscopy on dysuria immediately after permanent seed prostate brachytherapy (PB). It prospectively documents the time course and characteristics of dysuria, as well as the rates of urinary retention post-PB. Furthermore, this study attempts to establish the utility of routine, post-PB cystoscopy, by documenting the incidence of finding significant pathology on cystoscopy.Materials and methodsBetween January 2003 and January 2007, 225 patients deemed by their physician to be candidates for PB alone were recruited to the study. Patients who had external beam radiation therapy and/or androgen deprivation therapy were excluded. Preimplant International Prostate Symptom Score (IPSS), urinary quality of life score, urine leakage score, Sexual Health Inventory for Men score, and Radiation Therapy Oncology Group Bowel Health Inventory Scores were obtained. Patients were assigned to one of the following three groups: intraoperative rigid cystoscopy, flexible cystoscopy, or no cystoscopy following PB. Patient self-administered questionnaires were given to the patient in the recovery room after PB. These questionnaires evaluated the intensity, type, and duration of urinary symptoms associated with the first four urinations post-PB. All patients were seen on postoperative Day 1 when the surveys were retrieved. Patients were then followed up every 3 months. Acute urinary retention (AUR) was documented in the follow ups. Frequencies of significant pathology (defined as bladder tumor, urethral stricture, or large blood clots) were documented at the time of cystoscopy. AUR rates were also evaluated by the isotope used (I125, Pd103, or Cs131).ResultsA total of 225 patients were enrolled into this study, but only 194 patients could be analyzed for dysuria. Thirty-one patients were excluded from analysis (6, 13, and 12 patients from the rigid, flexible, and no cystoscopy groups, respectively). These patients did not return the questionnaire, or were in retention, and thus did not have dysuria scores to report. Baseline characteristics for the 194 patients in terms of preimplant IPSS, quality of life, prostate volume, and isotope used were well balanced between all three groups. There were no significant differences in dysuria between the three cystoscopy groups at any time point following PB. The mean dysuria score across all time points was 5.5 of 10, with 0 representing “no pain” and 10 representing “the worst possible pain.” Pain was most often characterized as “burning” (78%), whereas dysuria most commonly was “only during urination” (56%). AUR rates (6.8–9.5%) and duration of catheter dependence (10.5–19 days) were not found to be significantly different between the assigned groups. When results were stratified by isotope, patients treated with I125, Pd103, and Cs131 seeds experienced a 6%, 14%, and 0% retention rate, respectively. The I125 and Pd103 patients had similar pretreatment IPSS and prostate volumes. Seven percent of patients undergoing cystoscopy had significant findings. The most common finding was “clots thought too large to void” (3%). Seeds in the bladder/urethra occurred in 1% of cases. Only 0.7% of patients were found to harbor unsuspected bladder tumors.ConclusionThere was no significant difference in dysuria in the first four urinations post-PB between patients in the rigid, flexible, and no cystoscopy groups. Larger blood clots that may have been difficult to void, seeds in the bladder and/or urethra, and other abnormalities were found in 7% of patients who had cystoscopy. This may suggest that cystoscopy may be worthwhile post-PB. The incidence of AUR was not significantly different between the three cohorts. 相似文献

OBJECTIVE
To investigate whether narrow‐band imaging (NBI) flexible cystoscopy improves the detection rate of urothelial carcinomas (UCs) of the bladder. NBI is an optical image enhancement technology in which the narrow bandwidth of light is strongly absorbed by haemoglobin and penetrates only the surface of tissue, increasing the visibility of capillaries and other delicate tissue surface structures by enhancing contrast between the two.PATIENTS AND METHODS
Between November 2005 and May 2007 at the Queen Elizabeth Hospital, Birmingham, NBI flexible cystoscopy was performed on 29 patients with known recurrences of UC of the bladder after initial conventional white‐light imaging (WLI) flexible cystoscopy with the same instrument (Olympus Lucera sequential RGB endoscopy system).RESULTS
Subjectively, NBI provided a much clearer view of bladder UCs and in particular their delicate capillary architecture. Objectively, NBI detected 15 additional UCs in 12 of 29 patients (41%), as compared with WLI. The mean (sd ) difference was 0.52 (0.74) UCs per patient (P < 0.001, Wilcoxon signed‐rank test).CONCLUSIONS
Even in the few patients studied there is strong evidence that NBI differs from WLI in the number of UCs it detects, with a significantly increased detection rate. We feel that further evaluation of NBI flexible cystoscopy in more patients will show this technique to be highly valuable in the detection of both new and recurrent bladder UCs, and this work is continuing in our unit. 相似文献18.
OBJECTIVE
To confirm the recently published positive effect on visual analogue pain (VAS) scale levels for men watching their flexible cystoscopy.PATIENTS AND METHODS
From June 2007 to September 2007, 154 men had a flexible cystoscopy for various indications, all carried out by one urologist. Patients were randomized into two groups; those in group 1 were allowed to watch the video screen together with the urologist during the procedure; those in group 2 were not allowed to watch the procedure on the video screen. All patients received the same real‐time explanation during the cystoscopy. After the cystoscopy procedure the patients were asked to record their experience of pain on the 100 mm VAS as soon as they left the room. The two groups were further stratified by the number of previous cystoscopies experienced to evaluate the possible modifying effect of their previous experience.RESULTS
Although the results suggested a small decrease in perceived pain there were no statistically significant differences between the groups, regardless of cystoscopy experience.CONCLUSIONS
Our results show that, in contrast to an earlier report, the pain experienced by men undergoing a first or repeated flexible cystoscopy is not strongly influenced by watching the procedure. 相似文献19.
Office based flexible cystoscopy may be less painful for men allowed to view the procedure 总被引:2,自引:0,他引:2
PURPOSE: An experienced urology nurse observed that patients seemed to tolerate the procedure better when allowed to see the monitor in real time during office based cystoscopy. We assessed the impact of this on visual analog scale pain scores. MATERIALS AND METHODS: A total of 100 consecutive male patients underwent flexible cystoscopy, as performed by a single surgeon during the study period. Patients were randomized into 2 groups. Patients in group 1 were allowed to visualize the video screen with the surgeon, while patients in group 2 had the screen positioned so that only the surgeon could visualize the procedure. Water soluble lubricant was used on all endoscopes and all men received 10 cc 2% viscous lidocaine intraurethral before cystoscopy. No sedatives or analgesics were administered. All patients provided consent before the procedure and they were asked to record their pain experience on a 100 mm visual analog pain scale as soon as the surgeon left the room. RESULTS: Men who were allowed to visualize the cystoscopy had lower visual analog scale pain scores than those who were unable to visualize the screen (14 vs 23, Wilcoxon rank sum test p=0.02). CONCLUSIONS: To our knowledge no study has shown the impact of distraction of cystoscopic findings on procedure pain levels. Men viewing cystoscopy on the video monitor experienced an approximately 40% decrease in the pain level compared to those who did not view the procedure on the monitor. We encourage office urologists to incorporate this useful point of technique during flexible cystoscopy. 相似文献
