    Complications and specimen quality in transrectal ultrasound guided prostate biopsy: Comparison of 16G and 18G needles
    (2020) Bayraktar, Ahmet Murat; Olcucuoglu, Erkan; Hasirci, Eray; Nalbant, Ismail; Yesil, Suleyman; 0000-0002-4147-2966; AAI-7997-2021
    Objectives: To evaluate specimen quality, pathological results, complications and pain in transrectal ultrasound (TRUS) guided prostate biopsy using 16 gauge (G) or 18G biopsy needles Design: Retrospective study Setting: Turkiye Yuksek Ihtisas Training and Research Hospital, Ankara, Turkey Subjects: Retrospective analysis of 243 TRUS guided prostate biopsies between March 2011 and April 2016 Interventions: Group 1 (n=121) underwent TRUS guided prostate biopsy using a 16 G needle and Group 2 (n=122) underwent TRUS guided prostate biopsy with an 18 G-needle. Main outcome measures: We compared two biopsy needle sizes (16G vs 18G) in relation to sample quality, prostate cancer detection rate, pain, bleeding and infection rates in 243 patients. Core fragmentation and short specimen length (<10mm) rate were the sample quality criteria. Pain was evaluated using visual analog scale (VAS). Results: There were no statistically significant differences in mean patient ages, prostate-specific antigen values and prostate volumes between groups 1 and 2. Sixteen gauge needles caused significantly less fragmentation of the biopsy cores when compared to 18G needles (p=0.00), but no statistically significant difference between two groups was recorded for pathological results (p=0.72) and shorter specimen length (p=0.567). Haematuria, rectal bleeding and infection were similar in both groups. Mean VAS score of group 1 was significantly greater than that of group 2 (3.19 vs 2.66;p=0.027). Conclusion: Though thicker needles provided better sampling quality, the cancer detection rate was not altered by the needle size. Also, even though complication rates were similar for different needle sizes, the 18G needles were better tolerated.

    The Optimum Dosage of Prilocaine in Periprostatic Nerve Block During Transrectal Ultrasound Guided Prostate Biopsy: A New Approach in Dose Calculation
    (2016) Gonulalan, Umut; Kosan, Murat; Kervancioglu, Enis; Cicek, Tufan; Ozturk, Bulent; Ozkardes, Hakan
    Objective: We aimed to calculate the optimum dose of prilocaine per one mL prostate volume in periprostatic nerve block (PPNB) during transrectal ultrasound (TRUS) guided prostate biopsy (PBx). Materials and Methods: We retrospectively evaluated the medical records of 83 patients from whom 12 cores TRUS guided PBx were obtained between years 2011 and 2013. Prostatic sizes were evaluated separately as Size 1 (anterior-posterior on the axial plane), Size 2 (transversal), and Size 3 (cranial-caudal on the sagittal plane) for all patients. The visual analog scores (VAS) of the patients during PBx, prostatic volumes, and prilocaine doses per one mL prostate were evaluated. The correlation between VAS of patients during PBx and prostatic volume, the prostatic sizes and prilocaine dosage per one mL prostate was analyzed using Cubic regression test. Results: It was found that VAS scores of patients were significantly positive correlated with prostatic volume, Size 1, 2 and 3 (p<0.05). However, there was a negative significant correlation between VAS and prilocaine dose per one mL prostate volume (r=-0.402, p<0.01). The dose of 0.1 mL prilocaine infiltration per one mL prostatic tissue in PPNB was the maximum dose that caused a mild and under annoying pain (VAS<2) in patients according to cubic regression formula. Conclusion: Prilocaine dosage, prostatic volume and prostatic sizes (especially anterior-posterior and cranial-caudal) significantly affect VAS scores during TRUS guided PBx. The pain in TRUS guided PBx should be controlled with an optimum dose of prilocaine as 0.1 mL per one mL of prostatic tissue.
