RESUMO

OBJECTIVE: To develop performance metrics that objectively define a reference approach to a transurethral resection of bladder tumours (TURBT) procedure, seek consensus on the performance metrics from a group of international experts. METHODS: The characterisation of a reference approach to a TURBT procedure was performed by identifying phases and explicitly defined procedure events (i.e., steps, errors, and critical errors). An international panel of experienced urologists (i.e., Delphi panel) was then assembled to scrutinise the metrics using a modified Delphi process. Based on the panel's feedback, the proposed metrics could be edited, supplemented, or deleted. A voting process was conducted to establish the consensus level on the metrics. Consensus was defined as the panel majority (i.e., >80%) agreeing that the metric definitions were accurate and acceptable. The number of metric units before and after the Delphi meeting were presented. RESULTS: A core metrics group (i.e., characterisation group) deconstructed the TURBT procedure. The reference case was identified as an elective TURBT on a male patient, diagnosed after full diagnostic evaluation with three or fewer bladder tumours of ≤3 cm. The characterisation group identified six procedure phases, 60 procedure steps, 43 errors, and 40 critical errors. The metrics were presented to the Delphi panel which included 15 experts from six countries. After the Delphi, six procedure phases, 63 procedure steps, 47 errors, and 41 critical errors were identified. The Delphi panel achieved a 100% consensus. CONCLUSION: Performance metrics to characterise a reference approach to TURBT were developed and an international panel of experts reached 100% consensus on them. This consensus supports their face and content validity. The metrics can now be used for a proficiency-based progression training curriculum for TURBT.

RESUMO

Urology is a medical-surgical specialty that deals with the study, diagnosis and treatment of the medical and surgical diseases of the urinary apparatus and retroperitoneum in both sexes and the male genital apparatus without age limit, due to congenital, traumatic, septic, metabolic, obstructive and oncological conditions. Urologic oncology is the broadest urological part, where research and new advances make continuous learning essential. In this chapter we treat all academic features related with training in the field of Urooncology.

RESUMO

BACKGROUND: About 30-40% of men with localized prostate cancer undergoing radical prostatectomy will have cancer recurrence. It is estimated that one third recur locally and two thirds develop distant metastases with or without local recurrence. METHODS: In the present study we investigate the detection of prostate-specific antigen (PSA) mRNA in peripheral blood samples (n=200 patients) and pelvic lymph nodes (n=154 patients) by PSA reverse transcriptase polymerase chain reaction (RT-PCR) and compare these results to standard histological and immunohistochemical staging. RESULTS: We have observed a statistically significant correlation of lymph node PSA RT-PCR with standard pathologic risk factors, such as Gleason score (p=0.011), the presence of Gleason patterns 4 or 5 (p=0.005), lymph node metastasis (p<0.001) and a nearly significant correlation with the pT category (p=0.087). 39.5% (57/145) of the pN0 patients had PSA mRNA detectable in their lymph nodes. Blood PSA RT-PCR showed no correlation with the aforementioned factors and was even inversely correlated with preoperative serum PSA and lymph node status. Immunohistochemistry did not detect unsuspected prostate micrometastases in any pN0 patient. CONCLUSIONS: Lymph node PSA RT-PCR correlates with the Gleason score and the presence of Gleason patterns 4 or 5. Further clinical follow-up and correlation of RT-PCR status with overall outcome is required to allow validation of lymph node RT-PCR as a predictor of distant disease recurrence.
