Robot-assisted versus three-dimensional laparoscopic radical prostatectomy: 12-month outcomes of a randomised controlled trial.

OBJECTIVES: To compare functional and oncological outcomes of robot-assisted laparoscopic prostatectomy (RALP) to three-dimensional laparoscopic radical prostatectomy (3D-LRP) at 12 months after surgery. PATIENTS AND METHODS: Prospective randomised single-centre study of 145 consecutive men referred to radical prostatectomy in a tertiary referral centre in Finland. Patients were randomised 1:1 to the RALP (N = 75) and 3D-LRP (N = 70) groups. The primary outcome was urinary continence evaluated with the Expanded Prostate Cancer Index Composite 26-item version (EPIC-26) incontinence domain score at 12 months after surgery. Secondary outcomes included the use of protective pads at 12 months after surgery, EPIC-26 domain scores of irritative/obstructive, bowel, sexual and hormonal symptoms, positive surgical margin (PSM) rate, and biochemical recurrence (BCR). Complication frequency within the 3-month period after surgery was evaluated according to Clavien-Dindo classification. Statistical significance between groups was analysed using Mann-Whitney, chi-square and Fisher's exact tests. The trial was terminated after interim analysis based on no statistically significant difference in EPIC-26 urinary incontinence domain scores. Altogether 145 patients of the target accrual of 280 patients were recruited. RESULTS: Postoperative continence at 12 months after surgery according to the EPIC-26 incontinence domain was 79.25 in both groups (P = 0.4). Between group difference was -5.8 (95% confidence interval -15.2 to 3.6). There was no statistically significant difference in the rates of PSM or BCR between the two surgical modality groups. CONCLUSION: We were unable to demonstrate a difference between the RALP and 3D-LRP groups for functional and oncological outcomes at 12 months after surgery.

Visual Analogue Scale (VAS) in the Evaluation of Functional Outcomes After Three-dimensional Laparoscopic Prostatectomy.

OBJECTIVE: To assess suitability of visual analog scale (VAS) in the evaluation of functional outcomes after 3D laparoscopic prostatectomy (3D LRP) METHODS: Two hundred men underwent 3D LRP for localised prostate cancer at Seinäjoki Central Hospital in Finland between December 2013 and September 2018. In October 2019, an EPIC-26 survey along with VAS scales enquiring urinary (VAS-incontinence) and sexual (VAS-sexual) symptoms was mailed to the patients, and the correlations between these 2 methods were evaluated. In the EPIC-26 survey, scores for incontinence-(EPIC-26 UI) and sexual (EPIC-26-sexual) domains were calculated using the University of Michigan scoring system. In the VAS questionnaires, patient put a mark on the 10 cm long horizontal line in place, which described his experience of continence and potency. The Spearman rank correlation coefficient was used to evaluate the correlation between methods. RESULTS: The median scores were as follows: EPIC-26-UI, 79.25 (14.5-100); EPIC-26-sexual, 36.17 (0.0-100); VAS-incontinence, 8.8 cm (1.4-10.0); and VAS-sexual, 3.2 cm (0.0-10). The correlation coefficient between EPIC-26 UI and VAS-incontinence was 0.722 (95% confidence interval [CI], 0.63-0.79; p <.0001) and 0.883 (95% CI, 0.84-0.91; p <.0001) between EPIC-26-sexual and VAS-sexual. CONCLUSION: Our study shows a strong correlation between VAS and EPIC-26 urinary incontinence and sexual domains. In daily clinical practice VAS-scale may serve as a simple tool to evaluate the key functional outcomes of radical prostatectomy.

Visual Analogue Scale and Expanded Prostate Cancer Index Composite-26 in the Evaluation of Urinary Continence Recovery After Three-Dimensional Laparoscopic Radical Prostatectomy, a Single-Center Prospective Registered Study.

OBJECTIVE: To assess the correlation between the Visual Analogue Scale (VAS) and the Expanded Prostate Cancer Index Composite (EPIC)-26 in the evaluation of urinary continence (UC) recovery after 3-dimensional laparoscopic radical prostatectomy (3D-LRP). METHODS: 105 men underwent 3D-LRP in Seinäjoki Central Hospital Finland between November 2018 and February 2021. VAS forms and EPIC-26 questionnaires were used to assess UC preoperatively and at 6 weeks, 3-, 6-, 9-, 12-, 15-, 18-, 21-, and 24 months postoperatively. On the VAS form, the patient put a mark on the 10 cm long horizontal line in place, which described his experienced degree of UC (0 cm; fully incontinent-10 cm; fully continent). The scores for the urinary incontinence domain of EPIC-26 (UI-EPIC-26) were calculated and transformed to a scale of 0-100. Spearman´s rank correlation coefficient was used to evaluate the correlation between the VAS and UI-EPIC-26. RESULTS: A total of 915 VAS forms and 909 EPIC-26 questionnaires were evaluable. UC improved significantly during the first year but not after that. The medians for UI-EPIC-26 and VAS were 50.8 (0-100) and 7.2 cm (0-10 cm) at 3 months, 76.8 (14.5-100) and 8.7 cm (1.7-10 cm) at 12 months and 79.6 (8.25-100) and 9.0 cm (2.7-10 cm) at 24 months. The correlation coefficient (95% confidence interval) between VAS and UI-EPIC-26 preoperatively, at 12 months and at 24 months was 0.639 (0.505-0.743), 0.807 (0.716-0.871), and 0.831 (0.735-0.894), respectively (P < 0.001). CONCLUSION: The VAS can be utilized as an easy-to-use alternative to the EPIC-26 when evaluating UC recovery after 3D-LRP.

Role of hexaminolevulinate-guided fluorescence cystoscopy in bladder cancer: critical analysis of the latest data and European guidance.

OBJECTIVE: Hexaminolevulinate (HAL) is an optical imaging agent used with fluorescence cystoscopy (FC) for the detection of non-muscle-invasive bladder cancer (NMIBC). Guidelines from the European Association of Urology (EAU) and a recent, more detailed European expert consensus statement agree that HAL-FC has a role in improving detection of NMIBC and provide recommendations on situations for its use. Since the publication of the EAU guidelines and the European consensus statement, new evidence on the efficacy of HAL-FC in reducing recurrence of NMIBC, compared with white light cystoscopy (WLC), have been published. MATERIAL AND METHODS: To consider whether these new trials have an impact on the expert guidelines and on clinical practice (e.g. supporting existing recommendations or providing evidence for a change or expansion of practice), a group of bladder cancer experts from Denmark, Finland, Norway and Sweden met to address the following questions: What is the relevance of the new data on HAL-FC for clinical practice in managing NMIBC? What impact do the new data have on European guidelines? How could HAL-FC be used in clinical practice? and What further information on HAL-FC is required to optimize the management of NMIBC? RESULTS AND CONCLUSIONS: This article reports the outcomes of the discussion at the Nordic expert panel meeting, concluding that, in line with European guidance, HAL-FC has an important role in the initial detection of NMIBC and for follow-up of patients to assess tumour recurrence after WLC. It provides practical advice, with an algorithm on the use of this diagnostic procedure for urologists managing NMIBC.

3D laparoscopic prostatectomy: results of multicentre study.

INTRODUCTION: Three-dimensional laparoscopic prostatectomy (3D LRP) is a potentially cost-effective option for robot-assisted laparoscopic prostatectomy (RALP). Results for two-dimensional LRP and RALP are well documented; however, little has been published on the outcomes of 3D LRP. Our objective was to report the perioperative and short-term results of 3D LRP in a multicentre study. MATERIALS AND METHODS: In total, 496 unselected men with prostate cancer underwent 3D LRP by three surgeons between December 2013 and December 2018. Median age was 64 (43-76) years. Median prostate-specific antigen (PSA) was 7.9 (0.7-148) ng/ml. Preoperative and perioperative data and complications according to the Clavien-Dindo classification were collected. PSA and continence results were reported at 3 and 12 months postoperatively. Data were analysed with IBM SPSS statistics (25). RESULTS: Pathological Gleason score was 6 in 29%, 7 in 55.4%, 8 in 9.1%, 9 in 5.2% and 10 in 1.2% of patients. Pathological tumour classification was T2c in 59.5%, T3a in 19.5% and T3b in 10.9% of cases. Positive surgical margins occurred in 27.2%. Lymphadenectomy was performed in 36.3%, with positive lymph nodes in 11.8%. Median operative time was 137 (78-334) min and median blood loss 200 (10-1100) ml. Clavien-Dindo IIIa and IIIb complications occurred in 6.9% and 1.6%, respectively. At 3 and 12 months postoperatively, 90.2% and 91.4% of patients, respectively, had PSA <0.2 ng/ml, while 77.1% and 87.7% of patients were completely dry or using a maximum of one pad daily. CONCLUSIONS: 3D LRP shows promising results, comparable to similar studies published on RALP.

3D laparoscopic prostatectomy: A prospective single-surgeon learning curve in the first 200 cases with oncologic and functional results.

BACKGROUND: Studies for 3D-laparoscopic prostatectomy (3D-LRP) learning curve and surgical results are lacking. Combining 3D vision to LRP attenuates differences compared to Robotic assisted laparoscopic prostatectomy (RALP) with similar mini-invasiveness but lower costs. MATERIALS AND METHODS: Two hundred consecutive men with localized prostate cancer underwent 3D-LRP at Seinäjoki central hospital between 2013 and 2018. Oncological and functional results were documented. Long-term functional evaluation was done using EPIC-26 survey. Clavien-Dindo classification was used to assess complications during first 3 months. All operations were performed by a single surgeon (M.R.) with no experience of LRP or 3D-LRP. The learning curve was assessed by evaluating urethral anastomosis- and total operative time. Perioperative and postoperative data was collected prospectively during surgery and at subsequent control visits up to minimum of 1 year. RESULTS: A plateau in anastomosis time was reached after 30 cases and in operative time after 60 cases. Median operative time was 114 min (78-258 min) and median time for anastomosis was 25 min (11-90 min). Median blood loss was 150 ml (10-800 ml); 93.5% of the patients were discharged within the first 3 days. Clavien-Dindo ≥3a complications occurred in 6.5%. Positive surgical margins occurred in 23%. One-year after the operation, 93.3% had PSA ≤ 0.1; 91.9% of the patients were dry or used one daytime pad. EPIC-26 scores were as follows: Urinary incontinence 79.25 (14.5-100), urinary irritative/obstructive 93.75 (31.25-100), bowel 100 (33.33-100), sexual 36.17 (0-100) and hormonal 95 (37.5-100). CONCLUSION: The learning curve for 3D laparoscopic prostatectomy is comparable to RALP, which makes it a cost-effective alternative with comparable oncological and functional results.

[Scrotal masses in adulthood]. / Kivespussin resistenssit aikuisilla.

GPs often encounter patients with scrotal masses. Most of these are easily diagnosed by means of palpation and transillumination. Scrotal ultrasound is the primary radiological investigation, and should be done in cases of uncertain clinical diagnosis or when a solid mass in the scrotum is suspected. Benign processes such as hydrocele, spermatocele and varicocele are the most common causes for scrotal abnormalities. Symptomatic cases are treated with surgery or percutaneous sclerotherapy/embolization. Malignant testicular tumours, although less frequently seen, need prompt and accurate diagnosis and treatment. Radical orchidectomy is the primary treatment, followed by radiochemotherpy in selected cases.

Intravesical Bacillus Calmette-Guérin Versus Combination of Epirubicin and Interferon-α2a in Reducing Recurrence of Non-Muscle-invasive Bladder Carcinoma: FinnBladder-6 Study.

BACKGROUND: Patients with non-muscle-invasive bladder cancer (NMIBC) belonging to the intermediate-risk group should be treated with intravesical instillations to prevent recurrence and progression. OBJECTIVE: We compared the outcome of a monthly maintenance bacillus Calmette-Guérin (BCG) regimen with that of epirubicin (EPI) and interferon-α2a (IFN) in patients with NMIBC. DESIGN, SETTING, AND PARTICIPANTS: Our prospective randomized multicenter study comprised 229 eligible patients with frequently recurrent TaT1 grade 1-2 or low-grade NMIBC enrolled between 1997 and 2008. INTERVENTIONS: The four-arm study involved a single perioperative instillation of EPI plus five weekly instillations of BCG or EPI/IFN, followed by 11 monthly instillations in the 1-yr BCG or EPI/IFN maintenance arms, further followed by four additional quarterly instillations in the two 2-yr maintenance arms. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: Time to recurrence, progression, disease-specific survival, and overall mortality were analyzed using the Kaplan-Meier and cumulative incidence analyses plus the Cox and proportional subdistribution hazards models. RESULTS AND LIMITATIONS: The median follow-up time was 7.5 and 7.4 yr in the BCG and EPI/IFN groups, respectively. The probability of recurrence was significantly lower in the BCG group than in the EPI/IFN group. The probability was 39% versus 72% at 7.4 yr, respectively (hazard ratio [HR]: 0.41; 95% confidence interval [CI], 0.28-0.60; p<0.001). There was no significant difference in the probability of progression or in overall survival. However, there was a significant difference in disease-specific mortality in favor of the BCG group (HR: 0.20; 95% CI, 0.04-0.91; p=0.04). CONCLUSIONS: The monthly maintenance BCG regimen showed excellent efficacy and was significantly better in preventing recurrence than a similar regimen of EPI/IFN-α2a. PATIENT SUMMARY: A monthly bacillus Calmette-Guérin (BCG) regimen showed excellent efficacy and was significantly better in preventing recurrence than a similar regimen of epirubicin and interferon-α2a. TRIAL REGISTRATION: Registration was not considered necessary at this stage of the follow-up because the study was initiated as early as in 1997, before the current requirements concerning study registrations were implemented.

Charge-dependent targeting: results in six tumor cell lines.

BACKGROUND: Many previous studies show that cell surface sialylation of malignant cells is enhanced compared to normal tissue. The carboxyl group of the sialic acid yields, a negative surface charge of the tumor cells. This study investigates how tumor cell growth is affected when a cationic polymer is incubated with six different tumor cell lines. MATERIALS AND METHODS: Cationic dextran (CatDex) was prepared by periodate oxidation and subsequent coupling of cationic sidegroups by reductive amination. A fluorimetric cytotoxicity assay (FMCA) was used for the cell survival assay. Six different tumor cell lines (lung, breast, ovarian, prostate, colon, urinary bladder) were seeded into 96-well microtiter plates. CatDex was added at different microM concentrations and incubated for 72 h. Additionally, CatDex was fluorescence-labeled (FITC) and the interaction with the tumor cells was studied using fluorescence microscopy. The presence of sialic acid in the different cell lines was confirmed by using a FITC-labeled sialic acid binding lectin. RESULTS: CatDex showed a concentration-dependent growth inhibitory effect (i.e. the number of cationic side groups/dextran molecule and the molarity used). If the substitution was <20%, the growth inhibitory effect was small and difficult to reproduce. With 20-22% substitution, the growth inhibition varied between 20-95% depending on the molarity and the tumor type. Higher substitution resulted in complete cell death in all the cell lines. The fluorescent images showed intensive cell membrane interaction. CONCLUSION: Incubation with cationic dextran caused cell death in all six tumor cell lines. Our hypothesis is that CatDex binds to the anionic sialic acid residues and causes fatal disturbances in the cell membrane. However the exact mechanism remains to be elucidated. The results may indicate a new method of general interest for intra/local/regiolocal treatment of cancer. Clinical studies to explore this concept are pending.

Development of dextran derivatives with cytotoxic effects in human urinary bladder cancer cell lines.

BACKGROUND: In a previous study we reported on a new approach describing intravesical instillation of charged dextran in patients with superficial bladder carcinoma. The cationic derivative showed a strong tumor-selective accumulation. To develop this approach, the present study investigates the cytotoxic effect of cationic dextran derivatives on two urinary bladder cancer cell lines (J82 and 5637). METHODS: The dextran conjugates were prepared by periodate activation and subsequent coupling by reductive amination. A fluorimetric cytotoxicity assay (FMCA) was used for the cytotoxicity assay. The tumor cells were seeded into 96-well microtiter plates and different cationic dextran derivatives were added and incubated for 72 hours. RESULTS: The results showed that cationic epirubicin-dextran had a clear inhibitory effect on the growth in both cell lines (40-95% growth inhibition). The corresponding values for epirubicin (the reference) was 90-100% inhibition. Interestingly, cationic dextran had, by itself, a growth inhibitory effect. This cytotoxic effect could be strongly enhanced to be almost equal to the reference by changing the cationic sidegroup to aminohexane. Dextran alone showed no effect. CONCLUSION: The finding that cationic dextran by itself can be made cytotoxic, together with its capacity to accumulate in superficial bladder cancer, suggests possibilities for new therapeutic constructs. Cationic dextran with different cationic side-groups and in combination with cytotoxic drugs will be studied further. The cytotoxic mechanism needs to be elucidated.

Treatment of postoperative male urinary incontinence using transurethral macroplastique injections.

PURPOSE: To study the effect of Macroplastique injection on postoperative stress urinary incontinence (SUI) in male patients. PATIENTS AND METHODS: Since 1997, 50 consecutive men with a mean age of 66.0 years (range 51-75 years) suffering from mild to moderate postoperative SUI were treated as outpatients with transurethral Macroplastique injections. Under local anesthesia, 2.5 to 5 mL of Macroplastique was injected adjacent to the external sphincter at 5 or 7 o'clock or both. Forty-six patients had undergone radical prostatectomy, three transurethral prostatic resection, and one cystoprostatectomy with bladder substitution. Patients suffering from detrusor instability were excluded. A standardized 1-hour pad test and the patient's grading of the severity of the incontinence from 0 to 3, where 0 meant leaking took place all the time and 3 that the patient was completely dry, were carried out prior to injection and again at 3 months after each injection. Macroplastique injection was repeated if the initial treatment was not curative. RESULTS: The mean 1-hour pad test loss was 48.3 mL at baseline. After the first injection, 6 patients were completely dry and 28 improved; in the rest, no improvement was achieved. Forty patients underwent a second injection after which, 10 more patients became completely dry and 5 improved significantly. Twenty-three patients underwent a third injection, after which, 9 more patients were completely dry. Fourth injections were given to 8 patients, of whom 5 became dry, 1 improved, and 2 patients did not get any benefit. The total volume of Macroplastique injected ranged from 2.5 to 13.5 mL (mean 7.1 mL). A majority of the patients suffered some dysuria following the injection, but there were no significant side effects. CONCLUSIONS: The preliminary results of endoscopic treatment of mild to moderate postoperative SUI in males with outpatient Macroplastique injections are encouraging. To achieve satisfactory results, repeated injections are needed.

The role of BTA stat Test in follow-up of patients with bladder cancer: results from FinnBladder studies.

OBJECTIVES: To summarize the results of the FinnBladder studies of the BTA stat Test in follow-up of bladder cancer and more importantly to provide guidelines for daily clinical practise. METHODS: Voided urine samples of 501 patients were obtained prior to cystoscopy and split for culture, cytology and BTA stat testing. The overall sensitivity and specificity for the BTA stat Test were calculated, factors interfering with testing and the role of false positive test result were evaluated. RESULTS: Out of 501 patients 133 (26.5%) had a bladder cancer recurrence at cystoscopy, of which BTA stat Test detected 71 (53.4%). In the remaining 368 patients, 96 (26.1%) had a positive BTA stat Test result. An additional 9 (16.4%) recurrences were detected at further examinations. The overall sensitivities and specificities for the BTA stat Test and cytology were 56.0, 19.2 and 85.7%, and 98.3%, respectively. Urine infection and past BCG instillations and present instillations of any type caused false positive test result. Out of 79 patients with positive BTA stat Test and negative cystoscopy, 6 (7.6%) had recurrence at next scheduled follow-up cystoscopy. CONCLUSIONS: Although BTA stat Test cannot replace cystoscopy in the follow-up of patients with bladder cancer, it could replace routine cytology especially in patients with low-grade disease. Test should not be used in patients with urine infection, in those having received BCG, or in those with present instillation of any type. In case of positive test result but negative cystoscopy, urine cytology should be obtained as the first line examination. Positive cytology is the indication for further examinations, whereas patients with negative cytology might wait until the next scheduled cystoscopy.

Complement factor H as a marker for detection of bladder cancer.

BACKGROUND: The BTA TRAK and BTA stat tests for bladder cancer use monoclonal antibodies (mAbs) X13.2 and X52.1 to detect factor H (FH)-related material in urine. The exact ligands remain unknown. METHODS: Western blot analyses of purified FH, recombinant factor H-related protein 1 (FHR-1), and serum and urine samples were used to identify the ligands of X13.2 and X52.1. Recombinant FH constructs were used to identify the target sites of X13.2 and X52.1. To analyze whether natural ligands of FH could compete with its recognition by the capture mAb X52.1, we used surface plasmon resonance analysis. The role of the ligands of X52.1 in the BTA TRAK assay was tested with use of purified proteins and FH-depleted samples. RESULTS: X13.2 bound to domain 3 of FH and FH-like protein 1, whereas X52.1 bound to domain 18 of FH and to FHR-1. Using specific FH depletion from a bladder cancer patient's urine and purified FH, we demonstrated that FH is the ligand recognized by the BTA TRAK test. By contrast, FHR-1 in urine reduced the FH-dependent test signal. CONCLUSIONS: FH is a tumor marker for bladder cancer. To reveal the presence of bladder cancer, the BTA TRAK assay detects FH, whereas FHR-1 is able to partly inhibit this detection. This indicates a special mechanism for a diagnostic immunoassay based on the combined effect of simultaneous positive and negative signals in a single sample.

Perioperative single dose instillation of epirubicin or interferon-alpha after transurethral resection for the prophylaxis of primary superficial bladder cancer recurrence: a prospective randomized multicenter study--FinnBladder III long-term results.

PURPOSE: We evaluated the long-term efficacy of a single dose of interferon or epirubicin administered immediately after transurethral resection compared with transurethral resection alone for primary superficial bladder cancer recurrence. MATERIAL AND METHODS: A total of 200 patients with primary superficial stages Ta to T1, grades 1 to 3 bladder cancer were randomized into 3 treatment groups, including transurethral resection alone, transurethral resection plus 50 milliunits interferon-alpha2b and transurethral resection plus 100 mg. epirubicin. The primary end point was time to first recurrence. RESULTS: At a median followup of 72 months we observed a sustained effect of a single epirubicin instillation compared with other treatments. To date only 46% of the patients in group 3 have experienced recurrence in contrast to 73% and 68% in groups 1 and 2, respectively (p = 0.002). At 72 months the Kaplan-Meier disease-free estimates were 24%, 31% and 51% in groups 1 to 3, respectively (p = 0.002). The Cox multivariate model revealed a more than 2-fold relative risk of recurrence in group 1 versus group 3 (p <0.001). Other significant variables predicting recurrence were grade and the number of tumors. CONCLUSIONS: A single perioperative instillation of 100 mg. epirubicin causes a significant and sustained decrease in primary superficial bladder cancer recurrence, whereas a single dose of 50 milliunits interferon-alpha2b is ineffective for prophylaxis.

Differences between local and review urinary cytology in diagnosis of bladder cancer. An interobserver multicenter analysis.

OBJECTIVES: The objective of the study is to evaluate the agreement of local and review urinary cytology in patients with newly diagnosed bladder cancer and in those being followed for their disease. In addition, the effect of the type of institution on agreement was determined. METHODS: A total of 652 consecutive patients with bladder cancer from 19 institutions were evaluated; 575 (88.2%) of the patients had cytopathological sample available for central review and were eligible for analysis. One hundred and twenty nine (22.4%) of the patients had newly diagnosed bladder cancer, whereas the remaining 446 (77.6%) patients were under follow-up. A voided urine sample was obtained prior to transurethral resection of the bladder (TURB) or routine follow-up cystoscopy and split for culture and cytology. The cytopathological samples were first analysed by a local pathologist, and then re-analysed by a central reviewer. The agreement of cytological readings was determined by Kappa coefficient. RESULTS: The sensitivities of local and review cytology in detection of primary bladder cancer were 38.8 and 31.0%, respectively. Recurrence was observed in 119 of the 446 (26.7%) patients under follow-up, of which both local and review cytology detected 21 (17.6%) cases. Specificities of local and review cytology were 97.6 and 96.6%, respectively. Overall agreement of urine cytology was good in patients with primary bladder cancer and moderate in those being followed for their disease as Kappa coefficients were 0.70 and 0.60, respectively. However, some disagreement was found when results were analysed according to type of institution, to type of primary tumour, and to result of follow-up cystoscopy. In patients with primary bladder cancer the Kappa coefficient was 0.86 (very good) in university hospitals and 0.36 (fair) in city hospitals. Accordingly, in patients under follow-up the Kappa coefficient was 0.65 (good) in university hospitals and 0.39 (fair) in district hospitals. Although the stage of primary tumour had no effect on agreement, agreement was moderate (Kappa coefficient 0.45) in those with low grade tumour and good (Kappa coefficient 0.67) in those with high grade tumour. In addition, Kappa coefficients were 0.65 (good) and 0.40 (fair) in those with and without recurrence at follow-up cystoscopy. CONCLUSIONS: Although overall agreement of routine cytology was from moderate to good in both diagnosis and monitoring of bladder cancer, there is some variation in agreement according to the type of institution. Accordingly, grade of primary tumour and the result of follow-up cystoscopy had effect on agreement reflecting subjectiveness and weak reproducibility of this test. This not only emphasises the need for continuing education and quality control for urine cytologic analysis, but also inspires the development of more objective tests.
