Listening to music during cystoscopy decreases anxiety, pain, and dissatisfaction in patients: A pilot randomized controlled trial

PURPOSE To determine whether listening to music during cystoscopy decreases anxiety, pain, and dissatisfaction among patients and results in a more comfortable and better-tolerated procedure. MATERIALS AND METHODS Seventy male patients who underwent rigid cystoscopy between May 2011 and December 2011 were randomized into the following: no music (Group I, n=35) or classical music during procedure (Group II, n=35). Before cystoscopy, lidocaine gel was instilled in the urethra, and both groups viewed their procedures on a video monitor. Anxiety levels were quantified according to the State-Trait Anxiety Inventory. A visual analog scale (0-10) was used for a self-assessment of satisfaction, discomfort, and willingness among patients to repeat the cystoscopy. RESULTS Demographic characteristics, mean age, procedure duration, and procedure indications were statistically similar between the two groups. The mean anxiety level and mean pain score of Group II were significantly lower than those of Group I (p<0.001 for both). Group II also carried a significant greater mean satisfaction score compared with Group I (p<0.001). Statistically significant differences were detected between groups in the postprocedural pulse rate and the systolic blood pressure (p=0.012 and p=0.008, respectively), whereas preprocedure pulse rate and systolic blood pressure were similar. CONCLUSIONS Listening to music during rigid cystoscopy significantly reduces feelings of pain, discomfort, and dissatisfaction. Music can serve as a simple, inexpensive, and effective adjunct to sedation during cystoscopy. We recommend the application of music during rigid cystoscopy for clinical use.

Preoperative erythropoietin administration in patients with prostate cancer undergoing radical prostatectomy without transfusion.

Purpose In this study, we administered erythropoietin preoperatively to patients who underwent open radical prostatectomy without transfusion to increase their hemoglobin levels and investigated the efficacy of this procedure. Materials and Methods We evaluated 62 patients who underwent open radical prostatectomy performed by the same surgeon between June 2005 and January 2011. The 22 patients who refused transfusion were assigned to group 1; the patients who accepted transfusion were assigned to group 2. Before surgery, we administered erythropoietin beta to group 1 patients whose hemoglobin levels were <12 g/dL and retrospectively compared the clinical data of the two groups. We used the t-test and the chi-square test for statistical analysis. Results Mean preoperative hemoglobin levels in group 1 after erythropoietin administration (14.5 g/dL) were significantly higher than those in group 2 (13.59 g/dL, p=0.003). Moreover, the difference in the mean hemoglobin levels before and after surgery for group 1 patients (3.55 g/dL) significantly exceeded that for group 2 patients (2.08 g/dL, p=0.000). Additional analysis revealed no statistically significant differences in perioperative complications between the groups. Conclusions Preoperative erythropoietin administration increased the safety margin of hemoglobin levels, and this strategy worked sufficiently well in our experience.

Simultaneous robotic low anterior resection and prostatectomy for adenocarcinoma of rectum and prostate: initial case report

BackgroundWe report a case of synchronous rectal and prostate cancer treated successfully with simultaneous da Vinci robotic-assisted low anterior resection of the rectum and robotic-assisted laparoscopic radical prostatectomy to address both cancers.Case presentationRecently, minimally invasive surgical techniques using da Vinci robot® system (Intuitive Surgical, Sunnyvale, USA) were introduced as curative surgical modality of prostate and rectal malignancies. Herein, we report an initial case of simultaneous robotic low anterior resection and robotic prostatectomy for adenocarcinoma of rectum and prostate sharing a considerable number of port sites.ConclusionSimultaneous robotic-assisted low anterior resection could be performed with robotic-assisted radical prostatectomy safely and effectively in synchronous rectal and prostate cancer.

Primary Adenocarcinoma of the Rete Testis With Preceding Detection of Unilateral Hydronephrosis

Primary adenocarcinoma of the rete testis is a rare malignant testicular tumor with a poor prognosis. Here we report the case of a 54-year-old man with right hydronephrosis that was detected before the diagnosis of the primary testicular lesion. During the evaluation of the right hydronephrosis by use of abdominopelvic computed tomography, a painless, hard, solid lesion was found on the right testis. The patient underwent radical orchiectomy, and the pathologic examination revealed an adenocarcinoma of the rete testis. Multiple metastases were present at the time of diagnosis. The patient received combined chemotherapy after the surgery but lived only 8 months after the initial diagnosis.

Efficacy of Periprostatic Anesthesia according to Lidocaine Dose during Transrectal Ultrasound-Guided Biopsy of the Prostate

Purpose The aim of this study was to evaluate the efficacy of periprostatic lidocaine injection according to lidocaine dose during transrectal ultrasound-guided prostate biopsy. Materials and Methods The subjects of this study were 92 patients who had undergone transrectal ultrasound-guided 12-core biopsy of the prostate. The patients were randomly assigned to three groups: group 1 (n=31, no lidocaine injection), group 2 (n=30, periprostatic injection of 10 ml 1% lidocaine), and group 3 (n=31, periprostatic injection of 20 ml 1% lidocaine). The patients were assessed for pain by use of a 10-point visual analogue scale (VAS) and for other complications after the procedure. Results The mean VAS scores of groups 1 through 3 were 0.93±0.89, 1.32±1.37, and 1.13±1.10, respectively. There were no statistically significant differences between the three groups. However, the mean VAS score of the biopsy pain was 5.0±1.48, 3.93±1.94, and 3.60±2.15, in the same groups, respectively, with statistically significant differences between group 1 and the other groups. Patients in groups 2 and 3 reported significantly less biopsy pain than did group 1 patients (p=0.004, 0.021), with no statistically significant difference in VAS score between groups 2 and 3 (p=0.533). With respect to post-biopsy complications, there were no significant differences in the incidence of hematuria, hematospermia, rectal bleeding, or infection among the three groups. Conclusions Periprostatic injection of local anesthesia with lidocaine was associated with significantly less pain than in the absence of anesthesia. Furthermore, a 20-ml dose of lidocaine produced no better pain control than did a 10-ml lidocaine dose for prostate biopsy.
