RESUMO

PURPOSE: To identify independent risk factors for urethroplasty failure in a prospective dataset. METHODS: Since 2008, data of all male patients undergoing urethroplasty at Ghent University Hospital have been prospectively recorded and maintained. This analysis excluded: posterior strictures, strictures of the perineostomy, urethral malignancy-related strictures, age < 18 years and follow-up < 1 year. Postoperatively, a voiding cysto-urethrography (VCUG) was performed after 2 weeks and in absence of significant contrast extravasation, the transurethral catheter was removed. Patients were followed after 3 m, 12 m and annually thereafter. Failure was defined as stricture recurrence requiring additional urethral intervention(s). Uni- and multivariate Cox regression analyses were performed on the entire patient cohort and for one-stage urethroplasty (OSU) at specific locations. RESULTS: In total, 474 patients were included. Median follow-up was 62 m (IQR 35-91). Significant extravasation was present in 6.9%. Bulbar stricture location was identified as independent protective factor for urethroplasty failure (HR 0.44; p = 0.046) and significant extravasation at first VCUG was identified as independent risk factor for urethroplasty failure (HR 2.86; p = 0.005). Cox regression analyses for OSU at specific locations could not identify other risk factors. All but one (89%) of the failures preceded by significant extravasation at first VCUG occurred within 2 years of follow-up whereas 44% of the failures with no or insignificant extravasation at first VCUG occurred after 2 years of follow-up (p = 0.03). CONCLUSIONS: Bulbar stricture location is an independent protective factor for urethroplasty failure. Significant extravasation at first urethrography is an independent risk factor for urethroplasty failure and is associated with earlier stricture recurrence than other failed cases.

RESUMO

PURPOSE: We evaluated the surgical and functional outcomes, and the effect of the learning curve of nontransecting anastomotic repair for short bulbar and posterior urethral strictures. MATERIALS AND METHODS: A total of 75 patients were treated with nontransecting anastomotic repair for short bulbar strictures in 55 and for posterior strictures in 20. Surgical morbidity was scored using the Clavien-Dindo classification at 3 months. Sexual function was measured using SHIM (Sexual Health Inventory for Men) scoring preoperatively and postoperatively. Post-void dribbling before and after nontransecting anastomotic repair was also determined. To evaluate the learning curve outcomes were evaluated in patients 1 to 25, 26 to 50 and 51 to 75. RESULTS: Median followup was 30 months. Stricture recurred in 6 patients (8%), all diagnosed within 7 months after nontransecting anastomotic repair. Median operative time was 95 minutes and median hospital stay was 2 days. In 61 patients (81.3%) no surgical morbidity was recorded. Five (6.7%), 6 (8%) and 3 patients (4%) experienced a grade 1, 2 and 3b complication, respectively. Seven of 32 (21.9%) and 2 of 42 evaluable patients (4.7%) reported de novo erectile dysfunction and post-void dribbling, respectively, 3 months after nontransecting anastomotic repair. No difference in outcomes was observed among the 3 patient groups. CONCLUSIONS: Nontransecting anastomotic repair appears to be safe without a substantial learning curve effect. Patient counseling about possible surgical complications and transient erectile dysfunction is important.

RESUMO

OBJECTIVE: To determine the relationship of age to side-effects leading to discontinuation of treatment in patients with stage Ta-T1 non-muscle-invasive bladder cancer (NMIBC) treated with maintenance bacille Calmette-Guérin (BCG). PATIENTS AND METHODS: We evaluated toxicity for 487 eligible patients with intermediate- or high-risk Ta-T1 (without carcinoma in situ) NMIBC randomised to receive 3 years of maintenance BCG therapy (247 BCG alone and 240 BCG + isoniazid) in European Organisation for Research and Treatment of Cancer Genito-Urinary Group trial 30911. The percentage of patients who stopped for toxicity and the number of treatment cycles that they received were compared in four age groups, ≤60, 61-70, 71-75 and >75 years, using the Mantel-Haenszel chi-square test for trend. RESULTS: The percentage of patients stopping BCG for toxicity was 17.9% in patients aged ≤60 years, 21.9% in patients aged 61-70 years, 22.9% in patients aged 71-75 years, and 16.4% in patients aged >75 years (P = 0.90). For both systemic and local side-effects, there was likewise no significant difference. CONCLUSION: In patients with intermediate- and high-risk Ta-T1 NMIBC treated with BCG, no differences in toxicity as a reason for stopping treatment were detected based on patient age.

RESUMO

OBJECTIVE: The efficacy of intravesical chemotherapy in abolishing small papillary recurrences of non-muscle-invasive bladder cancer (NMIBC), the disease-free interval in responders and patients' preferences were explored. METHODS: When a small (≤1 cm) papillary recurrence of a NMIBC was diagnosed, the patient could choose between immediate transurethral resection of the bladder (TURB) or four weekly intravesical instillations with mitomycin C (MMC) or epirubicin (ERC). Control cystoscopy was scheduled 2-3 weeks after the last instillation. Complete remission was defined as total disappearance of all papillary tumours and negative cytology. RESULTS: 25 patients with 47 recurrence episodes were recruited from February 2003 until August 2011. The median follow-up was 35 months. After exclusion of 2 patients with intolerance to the instillations, 45 study episodes could be analysed. All patients to whom this was proposed preferred the instillations over immediate TURB. Complete, partial and no response was seen in 23 (51%), 6 (13%) and 16 (36%) out of 45 episodes, respectively. The median disease-free interval after complete remission was 16 months (95% confidence interval 9-24). CONCLUSIONS: Small papillary recurrences of NMIBC completely disappear in about half of the cases receiving four weekly bladder instillations with MMC or ERC. This is followed by a disease-free interval. Intravesical chemotherapy was preferred by all patients over immediate TURB.

RESUMO

OBJECTIVE: To explore the outcome of transurethral resection of the prostate (TURP) in the treatment of refractory recurrent acute bacterial prostatitis. PATIENTS AND METHODS: From 2004 to 2013, 23 TURP for this indication were performed in 21 patients; two patients underwent it twice. The files of these patients were retrospectively analysed for outcome and side effects. TURP intended to remove as much infected tissue as possible under appropriate antibiotherapy. RESULTS: Twelve patients became free of symptoms during a follow-up of 3-108 months (median 44), two others became disease-free after one and two postoperative attacks, respectively; eight were not cured and had rapid recurrences; three patients had follow-up of a few weeks only. Two failures developed orchiepididymitis shortly after the procedure and one a year later. No incontinence or bladder neck contracture was noted. CONCLUSION: TURP is an acceptable procedure in the treatment of refractory recurrent bacterial prostatitis. It could cure about two thirds of patients.

RESUMO

INTRODUCTION: Localized prostate cancer is increasingly treated by robot-assisted radical prostatectomy (RARP). We evaluated the introduction of RARP following a training program at a high-volume robotic center. MATERIALS AND METHODS: Before starting RARP, a young urologist followed a 6-month training program. The outcome of his first 50 RARPs was compared with the last 50 open radical prostatectomies (ORPs) performed by an experienced urologist at the same institution. Tumor characteristics were similar in both groups. Median follow-up was 12 (RARP) and 31 (ORP) months (p < 0.001). RESULTS: RARP was associated with more nerve sparing (82 vs. ORP 46%, p < 0.001), longer operation time [median 205 (range 120-310) vs. ORP 180 (85-280) min, p = 0.001], lower decline of postoperative hemoglobin [RARP -2.1 (0.1-4.5) vs. ORP -4.0 (1.0-7.0) g/dl, p < 0.001] and shorter catheter stay [6 (5-47) vs. ORP 14 (9-43) days, p < 0.001]. Complication rates were similar. Overall and pT2-positive surgical margin rate was 8 vs. 24% (p = 0.054) and 0 vs. 11.8% (p = 0.114) for RARP vs. ORP, respectively. One-year urinary continence rate was 76.7 (RARP) and 75.8% (ORP, p = 0.833). CONCLUSIONS: RARP was safely introduced after a training program in a high-volume robotic center, both surgically, oncologically and functionally.

RESUMO

The purpose of this pilot study was to evaluate the efficacy and safety of Salvia officinalis in controlling hot flashes in prostate cancer patients treated with androgen deprivation therapy (ADT). Ten patients experiencing hot flashes were included in a single-centre prospective pilot study. Treatment consisted of 150 mg of Salvia officinalis extract taken orally three times daily. A diary questionnaire scoring hot flashes, subjective side effects and quality of life (QOL) had to be completed. Clinical examination was performed at every visit and the concentration of ADT-linked hormones, haemoglobin and cholesterol was measured before, during and after ending treatment. Before the start of treatment, a 1 week baseline registration was performed. An analysis of variance with time of measurement as a within-subject factor was performed. When analysing the hot flashes score, one patient was excluded due to insufficient diary notes. The mean weekly score declined from 112 (SD = 71) at baseline to 59 (SD = 54) at the end of treatment (p = 0.002). Hot flashes diminished significantly from the first week up to and including week 3. This was maintained during treatment. There was no effect on QOL. There were no side effects. It is concluded that Salvia officinalis is efficient and safe in the treatment hot flashes, without improving QOL.

RESUMO

The objective of the present review was to evaluate the effect of population-based screening on the incidence of prostate cancer, prostate cancer tumor stage and grade, prostate cancer mortality, and overall mortality. A systematic review was carried out in April 2011, searching the Medline and Web of Science databases. The records were reviewed to identify comparative and randomized controlled trials evaluating the effect of screening on prostate cancer. Eight trials were identified containing personalized data on a screened versus a non-screened cohort. Prostate-specific antigen and digital rectal examination were the main screening tools. Prostate-specific antigen threshold and screening interval was not uniform among the different trials. Screening was associated with a significant increase in prostate cancer detection (relative risk 1.55; P=0.002), and a significant shift towards more localized (relative risk 1.81; P=0.01) and more low-grade tumors (relative risk 2.32; P=0.001). In overall analysis, no significant effect on prostate cancer mortality (relative risk 0.88; P=0.18) and overall mortality (relative risk 0.90; P=0.27) in favor of screening was observed. An adjusted analysis excluding papers with short follow up, high prostate-specific antigen contamination in the non-screening group and low participation in the screening group was able to show a significant reduction in prostate cancer mortality of 24%. The ideal screening strategy is unclear. Screening is associated with better PC detection and this in a more localized stage and of less aggressive tumors. Excluding the main shortcomings in screening studies (short follow up, high prostate-specific antigen contamination in non-screening group and low participation in screening group), screening is able to reduce prostate cancer mortality.

RESUMO

OBJECTIVES: To evaluate the outcome of different techniques of urethroplasty and to assess the quality of an in-home algorithm. METHODS: Two hundred fifty-two male patients underwent urethroplasty. Mean patient's age was 48 years (range 1-85 years). Data were analyzed for the failure rate of the different techniques of urethroplasty. An additional analysis was done based on an in-home algorithm. RESULTS: Median follow up was 37 months (range: 6-92 months). Global failure rate was 14.9%, with an individual failure rate of 11.7%, 16.0%, 20.7% and 20.8% for anastomotic repair, free graft urethroplasty, pedicled flap urethroplasty and combined urethroplasty, respectively. In free graft urethroplasty, results were significantly worse when extrapreputial skin was used. Anastomotic repair was the principle technique for short strictures (83.3%), at the bulbar and posterior urethra (respectively 50.8 and 100%). Free graft urethroplasty was mainly used for 3-10 cm strictures (58.6%). Anastomotic repair and free graft urethroplasty were more used in case of no previous interventions or after urethrotomy/dilation. Pedicled flap urethroplasty was the main technique at the penile urethra (40.7%). Combined urethroplasty was necessary in 41 and 47.1% in the treatment of, respectively, >10 cm or panurethral/multifocal anterior urethral strictures and was the most important technique in these circumstances. Two-stage urethroplasty or perineostomy were only used in 2% as first-line treatment but were already used in 14.9% after failed urethroplasty. CONCLUSION: Urethroplasty has good results at intermediate follow up. Different types of techniques must be used for different types of strictures.

RESUMO

OBJECTIVES: To explore indications for a definitive perineal urethrostomy (PU). To objectify the proportion of patients not completing the final stage procedure in an intended multi-stage urethroplasty. To analyze the incentives for both of these scenarios. MATERIALS AND METHODS: Since 2000, data of all men undergoing urethroplasty at our center have been collected in a database. This study included patients with a definitive PU and patients after ≥1 stages of an intended multi-stage urethroplasty. Patients <18 years or with a follow-up <3 m were excluded. Descriptive statistics were used and groups were compared with nonparametric statistical tests. RESULTS: Among 1015 urethroplasties, 34 patients underwent a definitive PU and 63 underwent ≥1 stages of an intended multi-stage urethroplasty with a median (IQR) follow-up of respectively 57 (31-120) and 32 (14-101) months. In the definitive PU group, patients were significantly older (P < .001) and had more cardiovascular comorbidity (P = .01), panurethral stricture disease (P = .02) and longer strictures (P = .02) than patients in the multi-stage urethroplasty group. Half of the definitive PUs were surgeon driven and 33% were patient driven. Final stage procedures were completed by 35/63 (56%) patients. Patients not completing the final stage were significantly older (P = .001). CONCLUSION: Definitive PU is particularly performed in older patients with worse cardiovascular condition, panurethral stricture disease and longer strictures. PU is often explicitly chosen by well informed patients and as nearly half of the patients refuse closure of the urethrostomy after the first stage, a definitive PU should be proposed as reasonable alternative to complicated urethral reconstruction from the start, especially in older patients.

RESUMO

OBJECTIVE: To report long-term surgical outcomes after urethroplasty for failed hypospadias repair (FHR) related strictures in adults. MATERIALS AND METHODS: A database of all adult (≥18 years) men who underwent urethroplasty since 2000 at Ghent University Hospital was created (prospective data since 2008). Patients with a follow-up <1 year or non-FHR related strictures were excluded. Postoperative complications were categorized according to Clavien-Dindo (<90 days), high-grade being ≥ grade 3. Failure was defined as stricture recurrence at the site of reconstruction requiring additional urethral manipulation. For penile strictures, outcomes were stratified per surgical technique. RESULTS: In total, 85 patients were included with a median (IQR) follow-up of 89 (57-165) months. Respectively 76, 6 and 3 patients had a penile, bulbar and penobulbar stricture. Postoperative complication rate was 27%. High-grade complications were seen in 7 of 85 (8.2%) patients and in 4 of 85 (4.7%) patients this involved fistula formation. Failure occurred in 29 of 85 (34%) patients, corresponding with a failure-free survival estimate (SD) of 82% (4.1), 73% (5.0) and 57% (6.7) after respectively 1, 5 and 10 years. For penile strictures, anastomotic repair had the highest failure rate (5/7, 71%) and a first stage Johanson procedure only had the lowest failure rate (1/10, 10%), followed by definitive perineal urethrostomy (1/4, 25%), pedicled flap urethroplasty (2/8, 25%) and free graft urethroplasty (7/23, 30%). CONCLUSION: FHR related strictures are predominantly seen in the penile urethra. Failure rate after urethroplasty for FHR related strictures increases steadily over time suggesting prolonged follow-up in these patients. For penile FHR related strictures, anastomotic repair should be discouraged.

RESUMO

OBJECTIVES: To explore the differences between primary and redo urethroplasty and to directly compare according stricture-free survival (SFS). Materials and Methods. Data of all male patients who underwent urethroplasty at Ghent University Hospital were collected between 2000 and 2018. Exclusion criteria for this analysis were age <18 years and follow-up <1 year. Two patient groups were created for further comparison: the primary urethroplasty (PU) group (no previous urethroplasty) and redo urethroplasty (RU) group (≥1 previous urethroplasty), irrespective of prior endoscopic treatments. A comparison between groups was performed using the Mann-Whitney U test and Fisher's Exact test. SFS was calculated using Kaplan-Meier statistics. A functional definition of failure, being the need for further urethral manipulation, was used. Uni- and multivariate Cox regression analyses were performed on the entire patient cohort. RESULTS: 805 patients were included. Median (IQR) follow-up of the PU (n = 556) and RU (n = 556) and RU (p=0.1). The RU group involved more penile strictures (p=0.1). The RU group involved more penile strictures (p=0.1). The RU group involved more penile strictures (p=0.1). The RU group involved more penile strictures (p=0.1). The RU group involved more penile strictures (p=0.1). The RU group involved more penile strictures (p=0.1). The RU group involved more penile strictures (p=0.1). The RU group involved more penile strictures (p=0.1). The RU group involved more penile strictures (. CONCLUSIONS: Several differences between primary and redo urethroplasties exist. Redo urethroplasty entails a distinct patient population to treat and is, in general, associated with lower stricture-free survival than primary urethroplasty, although more homogeneous series are required to corroborate these results. Prior urethroplasty and diabetes are independent risk factors for urethroplasty failure.

RESUMO

PURPOSE: We determined the current etiology of urethral stricture disease in the developed world and whether there are any differences in etiology by patient age and stricture site. MATERIAL AND METHODS: Between January 2001 and August 2007 we prospectively collected a database on 268 male patients with urethral stricture disease who underwent urethroplasty at a referral center. The database was analyzed for possible cause of stricture and for previous interventions. Subanalysis was done for stricture etiology by patient age and stricture site. RESULTS: The most important causes were idiopathy, transurethral resection, urethral catheterization, pelvic fracture and hypospadias surgery. Overall iatrogenic causes (transurethral resection, urethral catheterization, cystoscopy, prostatectomy, brachytherapy and hypospadias surgery) were the etiology in 45.5% of stricture cases. In patients younger than 45 years the main causes were idiopathy, hypospadias surgery and pelvic fracture. In patients older than 45 years the main causes were transurethral resection and idiopathy. In cases of penile urethra hypospadias surgery idiopathic stricture, urethral catheterization and lichen sclerosus were the main causes, while in the bulbar urethra idiopathic strictures were most prevalent, followed by strictures due to transurethral resection. The main cause of multifocal/panurethral anterior stricture disease was urethral catheterization, while pelvic fracture was the main cause of posterior urethral strictures. CONCLUSIONS: Of strictures treated with urethroplasty today iatrogenic causes account for about half of the urethral stricture cases in the developed world. In about 1 of 3 cases no obvious cause could be identified. The etiology is significantly different in younger vs older patients and among stricture sites.

RESUMO

PURPOSE: We retrospectively analyzed cases of anastomotic urethroplasty for posttraumatic urethral strictures that were done at our center. Surgical and functional outcomes were evaluated. The impact of previous urethral manipulations was assessed. MATERIAL AND METHODS: Between 1993 and 2006, 61 males were treated with anastomotic urethroplasty because of urethral trauma after pelvic fracture. Mean followup was 67 months (range 19 to 173). In 21 of the 61 cases (34.4%) urethral manipulation had been performed previously (secondary cases) but had failed. All patients were treated via the perineal approach. RESULTS: In 9 patients (14.8%) recurrence was reported. The recurrence rate was higher in patients who underwent former treatment than in primary patients (19% vs 12.5%). Posttraumatic impotence was reported by 20 patients (32.8%) but in 2 erectile function was restored after treatment. One patient had minor stress incontinence. In 2 secondary cases the rectum was injured during the procedure but could be repaired. CONCLUSIONS: Anastomotic urethroplasty via the perineal approach is an excellent treatment for posttraumatic urethral stricture. Results are good at long-term followup. Although statistical significance has not been attained, failures and complications seem to be higher in patients who have already undergone failed urethroplasty.

RESUMO

INTRODUCTION: Posterior urethral strictures after prostatic radiotherapy or surgery for benign prostatic hyperplasia (BPH) refractory to minimal invasive procedures (dilation and/or endoscopic urethrotomy) are challenging to treat. Published reports of alternative curative management are extremely rare. This is a preliminary report on the treatment of these difficult strictures by urethroplasty. MATERIALS AND METHODS: Seven cases were treated: 4 cases occurred after open prostatectomy or transurethral resection of the prostate for BPH, one case after external beam irradiation and 2 after brachytherapy. The 4 cases after BPH-related surgery were in fact complete obstructions at the bladder neck and the membranous urethra with the prostatic urethra still partially patent. Anastomotic repair by perineal route was done in all cases with bladder neck incision in the BPH-cases and prostatic apex resection in the radiotherapy cases. RESULTS: Mean follow-up was 31 months (range: 12-72 months). The operation was successful, with preserved continence, in 3 of the 4 BPH-cases and in 2 of the 3 radiotherapy cases. An endoscopic incision was able to treat a short re-stricture in the BPH-patient and a longer stricture at the bulbar urethra could be managed with a perineostomy in the radiotherapy-patient. CONCLUSION: Posterior non-traumatic strictures refractory to minimal invasive procedures (dilation/endoscopic urethrotomy) can be treated by urethroplasty using an anastomotic repair with a bladder neck incision if necessary.

RESUMO

CONTEXT AND OBJECTIVE: To present the updated version of 2008 European Association of Urology (EAU) guidelines on non-muscle-invasive bladder cancer. EVIDENCE ACQUISITION: A systematic review of the recent literature on the diagnosis and treatment of non-muscle-invasive bladder cancer was performed. The guidelines were updated and the level of evidence and grade of recommendation were assigned. EVIDENCE SYNTHESIS: The diagnosis of bladder cancer depends on cystoscopy and histologic evaluation of the resected tissue. A complete and correct transurethral resection (TUR) is essential for the prognosis of the patient. When the initial resection is incomplete or when a high-grade or T1 tumour is detected, a second TUR within 2-6 wk should be performed. The short- and long-term risks of both recurrence and progression may be estimated for individual patients using the scoring system and risk tables. The stratification of patients to low, intermediate, and high-risk groups-separately for recurrence and progression-represents the cornerstone for indication of adjuvant treatment. In patients at low risk of tumour recurrence and progression, one immediate instillation of chemotherapy is strongly recommended. In those at an intermediate or high risk of recurrence and an intermediate risk of progression, one immediate instillation of chemotherapy should be followed by further instillations of chemotherapy or a minimum of 1 yr of bacillus Calmette-Guerin (BCG). In patients at high risk of tumour progression, after an immediate instillation of chemotherapy, intravesical BCG for at least 1 yr is indicated. Immediate cystectomy may be offered to the highest risk patients and in patients with BCG failure. The long version of the guidelines is available on www.uroweb.org. CONCLUSIONS: These EAU guidelines present the updated information about the diagnosis and treatment of non-muscle-invasive bladder cancer and offer the recent findings for the routine clinical application.

RESUMO

Urethroplasty is considered to be the standard treatment for urethral strictures since it provides excellent long-term success rates. For isolated short bulbar or posterior urethral strictures, urethroplasty by excision and primary anastomosis (EPA) is recommended. As EPA only requires the excision of the narrowed segment and the surrounding spongiofibrosis, a full-thickness transection of the corpus spongiosum, as performed in the traditional transecting EPA (tEPA), is usually unnecessary. Jordan et al. introduced the idea of a vessel-sparing approach in 2007, aiming to reduce surgical trauma, especially to the dual arterial blood supply of the urethra, and, thus, potentially reducing the risk of postoperative erectile dysfunction or glans ischemia. This approach could also be beneficial for subsequent urethral interventions such as redo urethroplasty using a free graft, in which a well-vascularized graft bed is imperative. Nevertheless, these potential benefits are only assumptions as prospective studies comparing the functional outcome of both techniques with validated questionnaires are currently lacking. Moreover, vessel-sparing EPA (vsEPA) should at least be able to provide similar surgical outcomes as tEPA. The aim of this paper is to give an elaborate, step-by-step overview of how to manage patients with isolated short bulbar or posterior urethral strictures with vsEPA. The main objective of this manuscript is to outline the surgical technique and to report the representative surgical outcome. A total of 117 patients were managed according to the described protocol. The analysis was performed on the entire patient cohort and on the bulbar (n = 91) and posterior (n = 26) vsEPA group separately. Success rates were 93.4% and 88.5% for the bulbar and posterior vsEPA, respectively. To conclude, vsEPA, as outlined in the protocol, provides excellent success rates with low complication rates for isolated short bulbar and posterior urethral strictures.

RESUMO

To date, urethral stricture disease in men, though relatively common, represents an often poorly managed condition. Therefore, this article is dedicated to encompassing the currently existing data upon anatomy, etiology, symptoms, diagnosis, and treatment of the disease, based on more than 40 years of experience at a tertiary referral center and a PubMed literature review enclosing publications until September 2018.

RESUMO

INTRODUCTION: Non-muscle-invasive bladder cancer (NMIBC) is a highly recurrent disease. Early bladder chemotherapy instillation (EBCI) after transurethral resection (TURB) is an efficient way to diminish recurrence. However, this method is often challenged. Areas covered: There was a recent publication of a large meta-analysis with the original patient data and the largest study ever on EBCI. Both brought new evidence on EBCI. Also the results of the 2 trials of EBCI with apaziquone appeared. EBCI is discussed among other methods to decrease recurrence. Expert commentary: EBCI obtains a 35% relative reduction of recurrence with the best results in low risk tumors. However, tumors with an EORTC recurrence score of 5 or more do not respond. It should be given within a few hours after TURB. Mitomycin C and epirubicin have been most widely used with no difference in response. Intensive rinsing of the bladder is also able to reduce recurrence rates by about 21%. A rare, but major problem and reason for not using EBCI is the possible extravasation of the drug after TURB. Apaziquone is rapidly inactivated in tissue and blood and is therefore ideal for local use. Two phase III trials however obtained only a modest result.

RESUMO

Objectives To explore the effect of electromotive drug administration of mitomycin C (EMDA-MMC) using a single dose of intravesical mitomycin C (MMC) to avoid transurethral resection (TURBT) for small non-muscle-invasive bladder cancer. Material and methods All patients presenting small (<2 cm), single or multiple papillary bladder tumors were proposed to undergo a single EMDA-MMC instillation with 60 mg MMC before planning TURBT. The end point is complete disappearance of all papillary tumors at 2-4 weeks after EMDA-MMC. Results Thirty-six instillations were given to 32 patients. In general the treatment was well supported, except for two patients who had severe bladder spasms, resulting in early evacuation of the MMC. Complete response occurred in 28% (10/36 instillations). In 4 EMDA-MMCs with multiple tumors some tumors disappeared while others remained. In 61% (22/36) the tumors remained unchanged. Conclusion A single EMDA-MMC in l papillary bladder tumors <2 cm gives insufficient ablative effect.
