A multiplex quantitative methylation specific polymerase chain reaction assay determining the methylation status of GSTP1, APC and RASSF1 was strongly associated with repeat biopsy outcome up to 30 months after initial negative biopsy in men with suspicion of prostate cancer. Adding this epigenetic assay could improve the prostate cancer diagnostic process and decrease unnecessary repeat biopsies.

In conclusion, the UK urological community has embraced the need for laparoscopic urology, and looks forward to a proper training programme for its junior colleagues. We look to those charged with providing it to do so with haste. REFERENCES 1 Clayman RV, Kavoussi LR, Soper NJ et al.

Alfuzosin (10 mg) once daily significantly improved the rate of successful TWOC in patients with AUR related to BPH, even in elderly patients and those with a large drained volume who were at increased risk for TWOC failure. This should contribute to decrease the morbidity and mortality associated with emergency surgery and avoid the discomfort and potential morbidity associated with an in situ catheter.

12%). Of the TCCs in this group half were G3 and half were invasive (pT1±3). In the ONU group there were more ureteric tumours because of selection criteria and overall 16 (39%) were G3 and half were invasive. Information on nodal status was available in one LNU and two of the ONU reports. Within a mean follow-up of 32.9 months for LNU and 42.3 months for ONU, nine (21%) of the ONU group and four (16%) of the LNU group had died, with a mean survival of 15.1 and 17 months, respectively, after surgery (not signi®-cant). All of these deaths were associated with G3 pT1±3 disease. Conclusions In this series the case mix and outcomes were similar for those undergoing LNU and ONU. As laparoscopic renal surgery is associated with less postoperative morbidity it would seem reasonable to offer LNU to all patients with upper tract TCC, where appropriate and when there is no evidence of local invasion or metastasis. Because of the strong correlation between grade and stage, preliminary ureteroscopic assessment and biopsy may in¯uence the surgical approach adopted.

obtained from the hospital database and case-note review. RESULTSIn all, 164 patients with upper urinary tract TCC and 2197 with bladder TCC were identified. There was a correlation between grade and stage of both upper urinary tract and bladder TCCs. 35% of the upper tract TCCs were classified as grade 2 and 44% as grade 3, while for bladder TCCs, 31% of lesions were classified as grade 2 and 35% as grade 3 ( P = 0.003). Of the upper urinary tract lesions 33% were stage pT2-T4, compared with only 20% of bladder TCCs ( P = 0.001). CONCLUSIONSUpper urinary tract TCC is a higher grade and stage disease than bladder cancer, a finding that emphasizes the need for aggressive treatment of upper urinary tract TCC. If endourological management of upper urinary tract TCC is considered, histopathological determination of tumour grade before treatment is essential.
