BACKGROUND AND PURPOSE: Strictures of the vesicourethral anastomosis (VUA) following radical prostatectomy tend to recur. We used the holmium:YAG laser for treatment of recurrent stricture of the VUA. We evaluated the technique and its efficacy. PATIENTS AND METHODS: In 10 patients, the Ho:YAG laser was used with a 365-mum fiber at a setting of 2 J and frequency 10 to 20 Hz, creating a deep incision of the scar tissue at the 6 o'clock position. This was followed by a vaporizing resection of the remaining scar tissue between 3 and 9 o'clock. We aimed to vaporize up to well-vascularized surrounding tissue. Retrospectively, the charts were reviewed for hospital stay, voiding complaints, recurrence of stenosis, complications, and flow rates. The mean follow-up was 18 months. RESULTS: There were no operative complications. After removal of the catheter, all patients could void without difficulty. No re-treatment was needed for recurrent stenosis. Any existing irritative voiding complaints or incontinence did not change after treatment. In all patients, the flow pattern improved: the mean maximum flow rate increased, and the mean postvoiding residual volume decreased. CONCLUSION: The Ho:YAG laser seems to be a safe and effective treatment for first or recurrent strictures of the VUA after radical prostatectomy. 相似文献

Objectives
To determine the outcomes of open vesicourethral anastomotic reconstruction (VUAR) for outlet stenosis following radical prostatectomy (RP).Methods
Review of all cases of VUAR within an IRB-approved database was performed. Preoperative factors assessed included cancer treatment modality, duration of symptoms, prior treatments, and length of defect. Outcomes reviewed included length-of-stay (LOS), complications, maintenance of patency, continence, and need for additional procedures.Results
Twelve cases of VUAR performed by a single surgeon (BJF) from 2004 to 2012 were identified. Surgical approaches were either abdominal (7), perineal (3), or abdominoperineal (2). All patients underwent prior RP, with 25 % having subsequent radiotherapy. Among patients with stenosis, 43 % were completely obliterated. Two cases had prior anastomotic disruption in the early postoperative period after RP. The median length of stenosis was 2.5 cm (range 1–5 cm) and median LOS was 3.0 days (range 1–7 days). At a median follow-up of 75.5 months (range 14–120 months), 92 % of men retained patency; only 25 % were continent.Conclusion
In experienced hands, VUAR can restore durable patency for men afflicted with outlet stenosis after RP. Despite anatomic restoration, incontinence is likely. 相似文献8.

We report three cases with severe anastomotic strictures, which recurred several times after radical prostatectomy despite repeated treatments of urethral dilation, internal urethrotomy and/or transurethral resection. All three cases were finally treated with holmium laser successfully without any intraoperative or postoperative complications after repeated failures of each treatment. There were two specific characteristics in these three cases: the early onset of the stricture and the pinhole opening located on the top (12-o'clock) of the stricture wall. 相似文献

Abstract Objective. The aim of this investigation was to determine whether postoperative urine colour could be used as a predictor for the presence or absence of a urinary leakage at the vesicourethral anastomosis after open radical prostatectomy. Material and methods. In this prospective study, the urine colour of 223 patients who underwent open radical prostatectomy due to histologically proven localized prostate cancer was assessed macroscopically and microscopically on postoperative day (POD) 6, 7 and 8. All patients underwent evaluation of perianastomotic extravasation by retrograde cystography on POD 8. Baseline characteristics included age; prostate-specific antigen; prostate volume; tumour, node, metastasis classification; and Gleason score. Results. The urine colour was a highly significant predictor for perianastomotic extravasation in cystography when it was red on POD 6, 7 and 8. The sensitivity and specificity of urine colour as a predictor for extravasation were 71.4% and 83.2% on POD 6, 71.4% and 85.8% on POD 7, and 81.8% and 90.9% on POD 8, respectively, with a clear or slightly ensanguined urine colour. The negative and positive predictive values were 98.6% and 81.8%, respectively. Conclusion. A cystography can be omitted if the patient demonstrates a clear urine colour on POD 8, without an increased risk of missing a perianastomotic extravasation. 相似文献

Objectives
To re-evaluate safety and efficacy of transperineal reanastomosis (TPRA) as a viable therapeutic option in highly recurrent anastomotic strictures (AS) after radical retropubic prostatectomy (RRP).Methods
Retrospective analysis by standardized questionnaire inquiring for recurrence of stricture, stress urinary incontinence (SUI), sexual function, satisfaction, and changes in quality of life (QoL) was performed in all patients undergoing TPRA. Validated questionnaires (ICIQ-UI, EQ-5D, and IPSS) were included.Results
Median follow-up was 45.0 months. The average number of prior operations was 4.69. Success rate was 87% (20/23). Three recurrences were successfully treated via endoscopic means. All patients had urinary incontinence pre-op and post-op. Implantation of an artificial urinary sphincter (AUS) has been performed successfully in 73.9% (17/23). Rate of complications was low (8.7%; 2/23, Clavien–Dindo Grade II + III). EQ-5D-VAS showed a good general state of health (73.5/100). An improvement in QoL was noted in 63.6% (14/22) and patient satisfaction was high (72.7%; 16/22).Conclusions
This extended follow-up confirms the initial results for TPRA as an excellent treatment option for highly recurrent AS after RRP. Postoperative SUI as a consequence of transsphincteric urethral mobilization can be satisfactorily treated by the implantation of AUS. In case of AS recalcitrant to endoscopic treatment, the described procedure—even though technically challenging—represents a valuable treatment option.15.
A new approach for the treatment of vesicourethral anastomotic stricture after radical retropubic prostatectomy is presented. The patient had failed treatment with bougies, balloon dilation, and cold-knife incision of the anastomotic area. Transurethral resection of the bladder neck resulted in a rapid recurrence of the stricture. He was successfully treated with insertion of a UroLume urethral stent. After 18 months of follow-up, the patient is symptom free. 相似文献

Objectives: To assess the impact of laparoscopic radical prostatectomy on vesicourethral function and compare it to that of open radical prostatectomy.
Methods: Sixty-three patients undergoing laparoscopic radical prostatectomy for localized prostate cancer were included in this retrospective analysis. Urodynamic parameters, including maximum urethral closing pressure (MUCP), functional profile length (FPL), bladder compliance, maximum cystometric capacity (MCC) and detrusor overactivity, were considered. Continence status and changes in urodynamic findings before and after surgery were evaluated. In addition, postoperative urodynamic findings were compared with those in 58 patients undergoing open radical prostatectomy.
Results: After laparoscopic radical prostatectomy, MUCP and FPL showed a significant postoperative decrease. Continence rates after surgery were 82% in the laparoscopic and 78% in the open group. Comparison of postoperative data between continent and incontinent patients in both surgical groups showed significantly lower MUCP, shorter FPL, lower bladder compliance and higher incidence of detrusor overactivity in incontinent patients. Although there was no significant difference in postoperative MUCP and FPL between the two groups, bladder compliance was significantly lower and incidence of detrusor overactivity was significantly higher in the open prostatectomy group.
Conclusions: Laparoscopic radical prostatectomy has a negative impact on storage function by impairing function of the urethral sphincter and decreasing bladder compliance. There is no difference in postoperative urethral function between open and laparoscopic radical prostatectomy. Laparoscopic surgery might be associated with less impairment of bladder function than open surgery. 相似文献

OBJECTIVE: Stricture of the vesicourethral anastomosis remains a well-documented complication after radical retropubic prostatectomy. MATERIALS AND METHODS: We performed a retrospective study of 294 patients with prostate cancer who underwent radical retropubic prostatectomy. Possible correlations between anastomotic stricture formation, tumor stage, positive surgical margins, number of anastomotic sutures, bladder neck preservation, urine leakage, previous prostate surgery and/or intraoperative blood loss were examined. RESULTS: An anastomotic stricture was found in 18 cases (6%) requiring some kind of treatment. In 10 patients (56%), the bladder neck stricture occurred within 3 months after surgery, in 5 (28%) at 4-12 months after surgery and in 3 (16%) more than 12 months after surgery. Intraoperative blood loss (>1,000 ml) was found to be significantly correlated with urinary leakage (p < 0.001) and both correlated with anastomotic stricture formation (p < 0.005). CONCLUSION: Excessive intraoperative blood loss (>1,000 ml) and urine leakage was found to be significantly correlated to the formation of anastomotic stricture following radical retropubic prostatectomy. 相似文献
