PURPOSE: This study is designed to explore the role of retrograde urethrography as a predictor of recovery of urinary continence after radical retropubic prostatectomy. MATERIALS AND METHODS: A total of 40 patients who underwent radical retropubic prostatectomy from January 2005 to April 2007 were investigated. Among them one neurogenic bladder patient and one follow up loss patient were excluded. Voiding pattern and urinary incontinence were investigated with voiding diary monthly after Foley catheter removal. Recovery of urinary continence was defined as usage of less than 1 diaper per day. Pericatheter urethrography was conducted 2 weeks after operation. If definite bladder-urethral extravasation was not detected, an retrograde urethrography was performed immediately. 30 patients with sufficient length of urethra, regular margin of urethra and beaky appearance were defined as Group A, and 8 patients without above mentioned characteristics were marked as Group B. Differences between two groups were compared in terms of age, prostate volume, prostate specific antigen, urodynamic parameters, and duration of urinary incontinence. RESULTS: No significant differences were found in age, prostate volume, PSA between two groups. In group A, recovery rates of urinary continence were 70% (21 persons), 100% (30 persons) at 1,3 months after removal of catheter, respectively. In group B, rates of urinary continence recovery were 16.6% (1 person), 37.5% (3 persons), 75% (6 persons) at 1,3,4 months, respectively and 1 person regained continence at 7 months. CONCLUSION: A catheter free retrograde urethrography can be easily added after confirmation of bladder urethra anastomosis site healing. It gives us some valuable informations about external sphincter. The characteristics of retrograde urethrography can be used as a predictor of early recovery of postoperative incontinence.

Primary malignant melanoma occurring within the male urethra is very rare. Here we report a case of malignant melanoma of the urethra in a 74-year-old man. He presented with asymptomatic gross hematuria for 5 months. His glans penis and adjacent penile skin had become discolored black 10 years ago. Cystourethroscopy showed a smooth oval-shaped elevated mass in the fossa navicularis. There were no abnormal findings in the proximal urethra and urinary bladder. Computed tomography did not detect any inguinal lymph node enlargement or distant metastases. The patient underwent partial penectomy and ilioinguinal lymph node dissection. Grossly, the distal urethra revealed an ovoid pigmented nodule, that measured 1 x 0.5 cm. Microscopic findings showed a nodular malignant melanoma arising in the urethral mucosa with pagetoid spread to the epidermis of the glans penis. There were no recurrences over a period of 12 months after surgery without chemotherapy. This is the second case of a primary malignant melanoma of the male urethra in Korea.

PURPOSE: Several studies have shown that finasteride limits hematuria in patients with benign prostatic hyperplasia(BPH). However, there are few reports addressing dutasteride therapy. We evaluated the effect of dutasteride on intraoperative blood loss and on microvessel density(MVD) in patients with BPH. MATERIALS AND METHODS: We studied 39 patients with BPH who underwent transurethral resection of the prostate(TURP). Group I included 22 patients who received dutasteride 0.5mg daily for 2 weeks preoperatively, and group II included 17 patients who did not. Blood loss was evaluated by comparing preoperative and postoperative hemoglobin. Sections from the prostatic suburothelium and hyperplastic prostate were individually stained for CD 34. MVD was calculated by counting the number of positively stained blood vessels in 5 random high power fields. There were no significant differences between the groups in terms of age, total prostatic volume, resected prostatic weight, or prostate-specific antigen (PSA). RESULTS: The mean MVD in the suburethral portion in dutasteride-treated patients was significantly lower than that seen in untreated patients(14.47 versus 22.19 vessels per high power field, p=0.026). In nodular hyperplasia, there was no significant difference in MVD between the two group(14.72 versus 15.24 vessels per high power field, p=0.801). CONCLUSIONS: Short term pretreatment with dutasteride decreases suburethral prostatic MVD in patients with BPH and may help reduce blood loss during TURP, particularly in huge BPH, which sometimes bleeds excessively during operation.

PURPOSE: Transrectal ultrasonography (TRUS)-guided prostate biopsy causes fear and pain in 65% to 90% of patients. This study was designed to evaluated the use of intravenous propofol anesthesia during TRUS-guided prostate biopsy. MATERIALS AND METHODS: Between January 2006 and June 2008, 195 men undergoing a transrectal prostate biopsy were divided into 2 groups according to anesthetic technique. Group A consisted of 99 patients who received intravenous propofol infusion through an 18 gauge needle during TRUS-guided prostate biopsy. Group B consisted of 96 patients who intrarectally received 10 ml of 2% lidocaine gel 10 minutes before TRUS-guided prostate biopsy. Pain scores were assessed on a visual analogue scale immediately after prostate biopsy. RESULTS: The pain score was significantly reduced in group A compared with group B. There was a significant difference in the mean pain score between the 2 groups (1.0+/-1.3 in group A versus 2.9+/-2.0 in group B; p<0.01). Also, there was a significant difference in the willingness to undergo rebiopsy between the 2 groups (83.8% in group A versus 17.7% in group B; p<0.01). However, the complication rates were not significantly different between the 2 groups. Gross hematuria was found in 14% of group A patients and 18% of group B patients. CONCLUSIONS: Our results proved the advantage of intravenous propofol anesthesia during TRUS-guided prostate biopsy. Intravenous propofol infusion can be a safe and simple technique that significantly reduces pain during TRUS-guided prostate biopsy.

A primary signet ring cell carcinoma (PSRCC) of the urinary bladder is a rare variant of a mucin-producing adenocarcinoma. The prognosis of a PSRCC is poor, as silent progression in a linitis platica fashion leads to delayed diagnosis. Herein, the case of a PSRCC of the bladder, which extended to the prostate, which was treated with a cystoprostatectomy, is reported.

OBJECTIVE: Modic changes are signal intensity changes in adjacent vertebral bone marrow on magnetic resonance imaging. Few studies have investigated these changes with regard to the cervical spine. In this study, we investigated the associations between cervical degenerative disease and Modic changes. METHODS: We conducted a retrospective collection of radiological data in patients with neck pain at Pusan National University Yangsan Hospital from January 2010 to December 2014. A total of 169 patients were included in this study. Disc herniation grade, disc space height and global cervical lordosis (C2–C7 Cobb angle) were measured and analyzed. If Modic changes were present, we recorded the Modic change type based on the literature, vertebral level, age, sex, and surgical requirement. RESULTS: Sixty-six patients exhibited Modic changes in the cervical spine. Out of these 66 patients, Modic change type II (56 patients, 84.8%) and C5–6 vertebral level (23 patients, 34.8%) were the most predominant categories. Patients with Modic change showed worse outcomes in regard to disc herniation grade, disc space height and global cervical lordosis than patients without (p<0.01). Among 169 patients, 18 patients had undergone anterior cervical discectomy with fusion (ACDF). Patients with Modic changes (10 of 66 patients, 15.1%) had a greater probability of undergoing ACDF than those without (8 of 103 patients, 7.8%; p<0.01). CONCLUSION: Modic changes refer cervical degenerative changes, and incidence of ACDF is higher when the Modic changes are occurred.

PURPOSE: This study was designed to investigate the relationship between the histological composition of the prostate, preoperative clinical parameters, and the results of transurethral resection of prostate (TURP). MATERIALS AND METHODS: A total of 61 patients with benign prostatic hyperplasia (BPH) who had undergone TURP were enrolled retrospectively. Slides were surveyed for relative areas (%) of glandular epithelium (GE), stroma (ST), and smooth muscle (SM) in stroma by performing immunohistochemistry, and the mean outcomes were calculated with a computer-assisted image analyzer (x200). RESULTS: Total prostate volume was less than 40 ml in 19 patients (group 1), 40 to 80 ml in 23 patients (group 2), and more than 80 ml in 19 patients (group 3). The percentage of SM was significantly greater in group 1 (29.5+/-4.2%) than in group 3 (23.7+/-3.2%), but GE and ST did not differ significantly. AG number was significantly higher in group 3 than in the other groups but did not correlate with SM. Improvements in International Prostate Symptom Score, which were similar in each group, were positively correlated with SM. CONCLUSIONS: SM in prostate adenoma is increased in men with a small prostate and may play an important role in lower urinary tract symptoms in small BPH

OBJECTIVE: Serum C-reactive protein (CRP) concentrations and white blood cell (WBC) count are commonly used to identify postoperative wound infections. We investigated whether changes in serum CRP levels and WBC counts actually differed between patients undergoing revision spinal fusion surgery and those undergoing a primary fusion. METHODS: Patients who underwent posterolateral fusion (PLF) surgery at Pusan National University Yangsan Hospital between October 2013 and April 2015 were considered for this study. Sixty-seven patients with primary lumbar PLF (pPLF) and 21 with revision PLF (rPLF) were enrolled. A retrospective assessment of preoperative and postoperative CRP levels and WBC count was undertaken. Also, we gathered peak CRP day, and CRP normalization days. Comorbidity data were also obtained to evaluate any effects on the course of CRP and WBC count postoperatively. RESULTS: CRP levels peaked at 3 days after surgery. The maximum CRP values recorded for each group: 4.17 (standard deviation [SD], 4.18) mg/dL and 4.88 (SD, 3.03) mg/dL for pPLF and rPLF. This difference was not statistically significant (p=0.24). A rapid fall in CRP within 5–9 days was observed for both groups. CONCLUSION: Out of our expectation, changes in CRP levels after spinal fusion surgery follow the same course regardless of whether it is a revision operation or not. Because of this result, both the primary PLF surgery and revision PLF surgery should be monitored using CRP in the similar way and the antibiotic administration should be determined.

PURPOSE: Heat shock protein (HSP) 27 protects the cell by controlling apoptosis and immune reactions, and c-FLIP (cellular-FLICE inhibitory protein) inhibits apoptosis by inhibiting caspase-8 activity. We investigated the relationship of HSP27 and c-FLIP expression to prostate-specific antigen, Gleason score sum (GSS), and pathologic stage. MATERIALS AND METHODS: Samples from 163 patients between May 2004 and April 2010 were analyzed: 83 from patients that had underwent a radical prostatectomy, and 80 from those that underwent transurethral resection of the prostate to alleviate urinary symptoms from benign prostate hyperplasia. c-FLIP and HSP27 expression were observed by immunohistochemistry staining. Samples with less than 5% expression-positive cells were scored as 1, with 5%-50% were scored as 2, and with more than 50% were scored as 3. Local reactions were identified as 0.5 and evaluated. RESULTS: Both the presence of HSP27 within the tumor and the number of cancer cells positive for HSP27 were significantly correlated to GSS and pathologic stage (p<0.001, p=0.001, p<0.001, p<0.001). The same was true for c-FLIP expression (p<0.001). GSS was more highly correlated to HSP27 expression than to c-FLIP expression (r=0.814 for HSP27, r=0.776 for c-FLIP), as was pathologic stage (r=0.592 for HSP27, r=0.554 for c-FLIP). CONCLUSIONS: In prostate cancer, higher GSS and a more advanced pathologic stage were associated with a higher likelihood of having a HSP27-positive tumor and more HSP27-positive tumor cells. HSP27 expression was correlated with GSS and prostate cancer stage. A more advanced pathologic stage corresponded to a higher likelihood of having a c-FLIP-positive tumor and more c-FLIP-positive tumor cells. HSP27 expression had a higher correlation with prostate cancer stage and GSS than c-FLIP expression did.

OBJECTIVE: Several studies have reported that patients with diabetes mellitus (DM) are vulnerable to infection. However, the mechanism underlying this remains unclear. We hypothesized that preoperative blood glucose levels in patients with DM may be a risk factor for surgical site infection (SSI). We aimed to investigate the relationship between hemoglobin A1c (HbA1c) level and SSI incidence following single-level spinal fusion surgery. METHODS: Patients with DM who underwent single-level lumbar posterior fusion surgery were retrospectively reviewed. Ninety-two patients were included and classified into the SSI and SSI-free groups. Clinical data with demographic findings were obtained and compared. The HbA1c cut-off value was defined using receiver operating characteristic (ROC) and area under the curve (AUC) analyses, which showed a significantly increased SSI risk. Potential variables were verified using multiple logistic regression analysis. RESULTS: Among the enrolled patients, 24 had SSI and 68 did not within 1 year. The preoperative HbA1c level was higher in patients with SSI (6.8%) than in the non-infected patients (6.0%; p=0.008). ROC analysis showed that if the HbA1c level is higher than 6.9%, the risk of SSI significantly increases (p=0.003; AUC, 0.708; sensitivity, 62.5%; specificity, 70.6%). The preoperative HbA1c level was significantly correlated with SSI incidence, after adjusting for potential variables (p=0.008; odds ratio, 4.500; 95% confidence interval, 1.486–13.624). CONCLUSION: The HbA1c level, indicating glycemic control, in patients with DM may be a risk factor for SSI in single-level lumbar spine posterior fusion.
