Controlled Clinical Trial
Comprehensive evaluation of bladder and urethral dysfunction symptoms: development and psychometric validation of the Urinary Symptom Profile (USP) questionnaire.
To develop and validate a standardized tool assessing urinary symptoms among men and women with stress, urge, frequency, or urinary obstructive symptoms for use in clinical practice to complement clinical measures and diagnosis. ⋯ USP is the first valid and reliable questionnaire providing comprehensive evaluation of all urinary disorders and their severity in both men and women with SUI, OAB, and LS. It allows the screening and contributes to the differential diagnosis of these symptoms. The USP is a valuable tool for use in clinical practice.

To compare different tools for evaluate prostate-specific antigen (PSA) kinetics before prostate biopsy, such as PSA velocity, PSA slope, natural logarithm PSA slope (lnPSA slope), and PSA doubling time (PSADT). ⋯ The results for PSA, PSA velocity, PSA slope, and lnPSA slope were significantly higher in patients with prostate cancer than in controls. The results of the present study suggest that lnPSA slope may be useful for prostate cancer diagnosis. At the ROC analyses, the lnPSA slope AUC was better than that of PSA, PSA velocity, PSA slope, and PSADT.

Conformal radiotherapy with adjuvant androgen suppression is used in our center to treat localized prostate cancer. We compare Phoenix as an alternative to American Society of Therapeutic Radiology and Oncology (ASTRO) for defining biochemical failure. Our primary aim was to assess the Phoenix and ASTRO definitions of biochemical failure in a population of mainly Asian men with early localized prostate cancer treated with conformal radiotherapy with and without androgen ablation. ⋯ The ASTRO definition helped to standardize reporting of biochemical failures post-radiotherapy but inadequacies have been identified especially when adjuvant hormone therapy has been given. The Phoenix definition has been noted to be a more accurate and precise description of biochemical failure in international series, and we find this to be true in our Asian population as well.

Comparative Study
Productivity and cost implications of implementing electronic medical records into an ambulatory surgical subspecialty clinic.
Electronic medical records (EMRs) have been proposed as technology through which the quality of healthcare could be improved. We present an analysis of the cost and productivity implications associated with the transition from transcription to an EMR system in an ambulatory setting. ⋯ The results of our study have shown that the implementation of an EMR system when an economy of scale exists coincides with an increase in the revenue per encounter and per provider compared with transcription. The advantage of the fixed costs of an EMR system compared with the variable costs of a transcription-based system is the allowance of cash savings in an ambulatory surgical subspecialty practice.

Randomized Controlled Trial Comparative Study
Optimal approach for prostate cancer detection as initial biopsy: prospective randomized study comparing transperineal versus transrectal systematic 12-core biopsy.
Transperineal and transrectal prostate biopsy are both used for prostate cancer detection. However, which approach is superior remains unknown. In this study, we performed a prospective randomized study to compare the efficacy of transperineal versus transrectal 12-core initial prostate biopsy. ⋯ No significant differences were found in the cancer detection rate, cancer core rate, or complications between the two approaches. We believe that the preferred approach as an initial prostate biopsy is the transrectal approach, which does not require spinal anesthesia or another burdensome process.
