  • The aim of the study was to investigate the results of bladder irrigation with Water for Injection (WFI) after transurethral resection of bladder tumours for comparison with those for adjuvant use of BCG. A total of 239 patients (158 with single tumours, group A, and 81 with multiple tumours, group B) received continuous intravesical postoperative irrigation with WFI. Some 128 patients received intravesical irrigation with WFI, followed by weekly instillations of BCG (group C). Recurrence-free rate (RFR) and recurrence-free intervals (RFI) were recorded. RFR for those patients who received only intravesical irrigation with WFI (groups A and B) was 75.8%, 66.2% and 63.2% at the 1st, 2nd and 3rd year of follow up, respectively. Corresponding rates for group C were 61.7%, 55.4% and 49%. Median RFI in group B were 18, 11, 15, 15 and 12 months for Ta, T1, grade 1, grade 2 and grade 3 tumours, respectively. In group C corresponding intervals were 20, 33, 8, 20 and 42 months. BCG improved RFR only in T1 (p=0.014) and grade 3 tumours (p=0.007). In conclusion, postoperative bladder irrigation with WFI could increase RFR during the first and second year of follow up.

  • Aim: To study the causes and significance of both microscopic and macroscopic haematuria in adult patients and assess possible relevance to early detection of urological cancers. Methods: 417 patients presenting with haematuria were assessed in our Urology Unit. Following confirmation of haematuria, these patients were subjected to imaging techniques and flexible cystoscopy. Parameters analysed included clinical characteristics, imaging results, flexible cystoscopy findings, time delay to diagnoses and eventual treatment and final diagnoses of all cases. Results: 390 haematuria cases were analysed from 417 consecutive patients with haematuria. After 27 cases were excluded as they had previous history, 245 microscopic and 145 macroscopic. Age range was 17 to 95 years old with predominance of 152 females to 239 males. The racial distribution included 180 Chinese, 100 Indians,95 Malays and 15 other races. The final diagnoses were benign prostatic hyperplasia (22.6%), no cause found (22.3%), other causes (18.7%), urolithiasis (11.5%), urinary tract infection UTI (10.8%), non specific cystitis (10.3%), bladder tumours (2.8%) and other genitourinary tumours (1%). 11 new cases (2.8%) of bladder cancers were diagnosed, with a mean age of 59 years. Only 3 of 245 (1.2%) patients with microscopic haematuria had newly diagnosed bladder tumour compared with 8 of 145 (5.5%) patients with frank haematuria (p=0.016). Mean time taken from onset of symptoms to diagnosis of bladder cancer was 53.3 days with definitive treatment (TURBT) in 20.1 days from diagnosis. Conclusion:- This study has highlighted the common causes of haematuria in our local setting. We recommend that full and appropriate investigations be carried out on patients with frank haematuria especially those above 50 years old in order to provide earlier detection and prompt management of bladder diseases especially tumours.

  • Background: Depending on various pathological factors, non muscle invasive bladder cancer (NMIBC) shows varying degrees of recurrence. The aim of this study was to determine the incidence of recurrence of NMIBS in our centre, study the influence of intrinsic tumour characteristics like grade, stage, size and number, and compare our results with data in the published literature. Materials and Methods: A hospital based retrospective study was conducted on patients who underwent treatment for NMIBC from 2011 to 2014. The factors studied were number, size, grade, stage and site for correlation with recurrence. Statistical analysis was performed using Medcalc version 12, using Pearson's Chi square test to ascertain associations between variables. Results: A total of 73 patients with NMIBC were studied of which 48 (65.8%) had low grade and 25 (34.2%) had high grade tumours. Some 38 patients (52.1%) had Ta tumours, 34 (46.6%) had T1 and one had CIS. Mean follow up was 34.3 months. Recurrence rates were found to be 33.3% in low grade and 52.0% in high grade tumours. The overall recurrence rate in our centre was 39.7%. Significant correlations were seen between stage and recurrence, with a rate of 15% for Ta and 63.3% for T1 tumours. Fourteen out of 21 bladder cancers (66.6%) with multiple tumours demonstrated recurrence (p=0.006). Grade, size and site had no influence. Conclusions: In our study, recurrence of NMIBC was found to be directly proportional to stage and number of primary tumours, but not grade, size and site. The incidence of recurrence of NMIBC both stage wise and grade wise in our centre was also low compared to the data in the published literature.
