ABSTRACT
Performance of 16 (16 g) (n=103) and 18 gauge (18 g) (n=101) biopsy needles in transrectal ultrasound (TRUS)-guided 10-core prostate biopsies were compared in terms of cancer detection and pre-defined specimen quality criteria in this prospective randomized study. Cancer detection rates of the two groups were similar, although the mean core volume of 16 g needles was almost twice that of 18 g needles. On the other hand, using 16 g needles significantly improved specimen quality by acquiring less empty cores, small cores and fragmented cores. There were no significant differences among the complication rates and VAS pain scores of the two groups. Sixteen gauge needles can safely be used in TRUS-guided prostate biopsies, as they improve specimen quality without increasing morbidity and patient discomfort.

OBJECTIVE: To determine if the American Urological Association (AUA) Symptom Index is an accurate and reliable instrument for use in assessing the outcome after urethroplasty. PATIENTS AND METHODS: The AUA Symptom Index questionnaire was answered by 33 men (mean age 31.3 years) who underwent end-to-end urethral reconstruction after complete urethral disruption; the index was completed at a mean of 6 months after surgery. The scores were then correlated with maximum flow rates (Qmax) and presence of re-stenosis on retrograde urethrography. RESULTS: The initial mean (SD) AUA score was 10.42 (9.6) and the Qmax 22.12 (9.37) mL/s. Of the 33 patients, six (18%) had re-stenosis, with a mean score of 30 and Qmax of 6 mL/s. There was a significant inverse correlation between the AUA symptom score and Qmax (r = - 0.401, P < 0.05). CONCLUSION: The AUA Symptom Index is inversely correlated with Qmax and may indicate the presence of re-stenosis after urethroplasty. The AUA score can thus be used as a cost-effective and easy method in the first-line screening of the outcome of urethroplasty.
