AIMTo evaluate the effects of metabolic profiles on lower urinary tract symptoms (LUTS) in men with erectile dysfunction (ED).

METHODSA total of 75 impotent men aged 25-75 years old (mean 58.1 years) were included in the study on a prospective basis. Patients were evaluated with a complete history, physical examination, anthropometry and metabolic profiles. LUTS were assessed using the International Prostate Symptom Score (IPSS).

RESULTSOverall, there was no correlation between the IPSS and continuous parameters. However, when continuous variables were categorized, some parameters were significantly associated with LUTS. Patients with triglyceride level of 150 mg/dL or higher had more severe symptoms than those with triglyceride levels less than 150 mg/dL (19.4 +/- 2.4 vs. 14.3 +/- 1.1, P = 0.033). When 40 mg/dL was chosen as the high-density lipoprotein (HDL)-cholesterol cut-off level, the IPSS was significantly different between the two groups divided by 40 mg/dL (19.4 +/- 2.6 for HDL-cholesterol < 40 mg/dL vs. 14.4 +/- 1.0 for HDL-cholesterol = or > 40 mg/dL, P = 0.042). The area under the receiver operating characteristic curve (AUROCC) of triglyceride was 65.7% (95% confidence interval [CI], 52.6%-82.3%; P = 0.034) for severe LUTS. However, the AUROCC for 'HDL-cholesterol' was not significant (area, 65.4%; 95% CI, 48.2%-82.7%; P = 0.062). No other factors were determined to be significant in this regard.

CONCLUSIONThe results of the present study indicate that some metabolic profiles might influence LUTS in men with ED.

Recurrent disc herniation and postoperative fibrosis are the main disease entities causing failed back surgery syndrome (FBSS) and magnetic resonance (MR) imaging has become a major diagnostic modality in differentiating the two. To observe the variable entities of FBSS and their MR findings, we retrospectively analyzed 15 MR images in 12 patients. The causes of FBSS were as follows; normal (no organic cause), fibrosis, new or recurrent disc herniation, discitis, osteomyelitis, inflammation at operation site, epidural abscess, arachnoiditis, and hematoma. Except a case of hematoma, gadolinium enhancement scan was necessary and informative in the diagnosis of FBSS and MR imaging only was not enough in the diagnosis of arachnoiditis.

PURPOSE: This study was initiated to establish the hazard ratios for risk of urinary stone formation in chronic spinal cord injury (SCI) patients. MATERIALS AND METHODS: A total of 140 male patients who were injured before 1987 were eligible for this investigation and they were followed up on a yearly basis from January 1987 and December 2003. RESULTS: Over the 17 years, 39 patients (27.9%) and 21 patients (15.0%) were diagnosed with bladder and renal stones for a total of 59 and 25 episodes, respectively. On multivariate analysis, bladder stone was more common for the patients who were injured at 24 years old or older than is was for those patients who were injured at less than 24 years old (odds ratio [OR]: 2.490; 95% confidence interval [CI]: 1.092-5.677; p=0.030). In another model, the patients with complete injury had a greater risk of renal stone formation than those with incomplete injury (OR: 4.095; 95% CI: 1.295-12.944; p=0.016). We also found that renal stone was more common for the patients with urethral catheterization (UC) than for the patients who could spontaneous void (OR: 5.668; 95% CI: 1.306-24.604; p=0.021), and for patients with bladder stone than for those without bladder stone (OR: 4.678; 95% CI: 1.447-15.126; p=0.010). CONCLUSIONS: Injury characteristics are important for the development of urinary stone in chronic traumatic SCI patients. In addition, our findings suggest that for the cases who cannot undergo intermittent catheterization or when the bladder cannot empty spontaneously, suprapubic cystostomy is better than UC is regards to renal stone formation in this population.

Various laparoscopic nephroureterectomy techniques for urothelial carcinoma of the upper urinary tract have been developed to minimize postoperative discomfort and the necessity for a lengthy convalescence. We performed hand-assisted retroperitoneoscopic nephroureterectomy without hand-assisted device in 3 male patients with urothelial carcinoma of the distal ureter. Average operative time and estimated blood loss were 251 min (range 235 to 280) and 250 mL (range 200 to 300), respectively. Complication did not occur and conversion to open surgery was not necessary in all cases. Postoperative analgesic requirements were moderate and the time to regular diet intake averaged 3 days (range 2 to 4). None of the patients had a positive margin on the final pathologic specimen. At the average follow-up of 8.1 months, no regional recurrence, port-site metastasis, bladder recurrence, or distant metastasis were noted in any patient. We described our initial experience with the described technique, which obviates the need for midprocedural patient repositioning.

Acute airway obstruction after anterior cervical surgery is rare, but does occur. Airway obstruction due to prevertebral soft tissue swelling is unpredictable, but potentially lethal. We managed a 67-year-old male who developed acute airway obstruction caused by marked prevertebral soft tissue swelling on the first day after anterior cervical discectomy and fusion at the C4-C5 level.

For the patients suffering from extensive deep vein thrombosis (DVT), the placement of an inferior vena cava (IVC) filter in conjunction with anticoagulant therapy has been used to prevent pulmonary embolisms. However, for the patients who anticoagulant is contraindicated or if this is complicated, the use of an IVC filter without concurrent anticoagulation may become the sole treatment for pulmonary embolisms. In this situation, the thrombi trapped in the IVC filter may cause significant clinical problems. We report here on a case of IVC filter thrombosis that was successfully treated by aspiration thrombectomy after placing another filter proximal to the previous filter.

PURPOSE: To identify the predictors of death from other causes in patients with localized renal cell carcinoma (RCC). MATERIALS AND METHODS: We identified 1,101 patients with pathologically confirmed T1 or T2 RCC with a follow-up duration of over 6 months. Survival according to the cause of death was evaluated by using the Kaplan-Meier analysis with log-rank test. Prognostic factors for death from other causes were assessed by multivariate analysis using the Cox proportional hazard regression model. Once the prognostic factors were identified, a risk-group variable was created by counting the number of unfavorable features present for each patient. RESULTS: The median follow-up was 62 months, and RCC-related death occurred in 50 patients (4.5%), whereas death from other causes occurred in 47 (4.3%). Patients who died from other causes had a higher American Society of Anesthesiologist (ASA) score (26.1% vs. 10.2%; p=0.044), older age (63.4 years vs. 55.0 years; p<0.001), smaller mass size (5.1 cm vs. 7.9 cm; p<0.001), and lower nuclear grade (p=0.003). In the multivariate Cox regression analysis, older age, higher ASA score, and lower body mass index were independent factors predicting death from other causes in patients with localized RCC. On the basis of the number of risk factors for death from other causes, the 5-year other-cause-specific survival was 98.3% (0 risk factors), 84.7% (1 risk factor), and 67.6% (2 or 3 risk factors), respectively (p<0.001). CONCLUSIONS: Older age, higher ASA score, and lower body mass index were independent predictors of death from other causes in patients with localized RCC.

PURPOSE: This study evaluated the demographics and semen parameters of males with cancer who banked their sperm prior to chemotherapy. MATERIALS AND METHODS: This is a retrospective study of 66 cases referred for sperm banking prior to initiation of chemotherapy over a 15-year period (1999~2014). Patients who had previously received cancer treatment including chemotherapy or radiotherapy were not included in this study. RESULTS: We studied a total of 66 cancer patients referred for cryopreservation of sperm prior to chemotherapy. The mean age of the patients at the time of banking was 32.0+/-7.9 years (range, 19~58 years). The types of cancer were testicular cancer (31 cases, 47.0%), non-Hodgkin's disease (10 cases, 15.1%), Hodgkin's disease (5 cases, 7.6%), leukemia (8 cases, 12.1%), gastrointestinal malignancy (5 cases, 7.6%), and musculoskeletal malignancy (5 cases, 7.6%). There were significant differences in sperm concentration and viability among the various types of cancer, but no significant difference in semen volume or sperm motility and morphology. CONCLUSIONS: In this study we found that sperm quality could decrease even before chemotherapy. Because chemotherapy can also negatively affect spermatogenesis, sperm cryopreservation prior to treatment should be strongly recommended for cancer patients of reproductive age.

We analyzed the peripheral blood of patients with gastrointestinal tract cancer at different stages to assess the presence of carcinoembryonic antigen (CEA) mRNA by reverse transcriptase-polymerase chain reaction (RT-PCR), which we used as an indicator for micrometastatic malignant cells. A total of 35 gastric, 24 colorectal, 4 esophageal and 4 biliary tract cancer patients and nine normal healthy subjects were studied. No CEA mRNA was detected in the nine normal healthy volunteers. CEA mRNA was detected in 100% (10/10) of metastatic, 33.3% (3/9) of early gastric cancer (EGC), and 18.8% (3/16) resectable gastric cancer patients, respectively. In colorectal cancer, 55.6% (5/9) of metastatic cancers were positive for CEA mRNA, and 26.7% (4/15) Duke stage B/C showed positive. One patient with stage III gastric cancer who was negative CEA mRNA initially and turned positive during follow-up, developed multiple bone metastasis one month later. Another stage III patient, who was positive for CEA mRNA, preoperatively revealed early relapse in two months. These results suggest that the identification of circulating tumor cells using RT-PCR for the detection of CEA mRNA is feasible and this analysis may be a promising tool for early detection of micrometastatic circulating malignant cells in patients with gastrointestinal tract cancer.

PURPOSE: We wanted to compare the early outcome of laparoscopic radical prostatectomy(LRP) as performed by a laparoscopic surgeon without experience with retropubic prostatectomy(RRP), and open RRP as performed by an oncologic surgeon without experience with LRP. MATERIALS AND METHODS: We reviewed the clinical data on the initial 31 LRPs(group 1) and the 107 RRPs(group 2), as performed by two surgeons at our institution. The two different surgeons performed each type of operation, respectively. Although each surgeon was an expert of laparoscopic surgery and open surgery respectively, they were unfamiliar with radical prostatectomy. RESULTS: The mean operation time was longer in group 1 than in group 2(303 minutes vs. 207 minutes, respectively, p<0.001). However, the estimated mean blood loss(685ml vs. 1,488.0ml, respectively, p<0.05) and the transfusion rate(24.1% vs. 55%, respectively, p<0.05) were significantly less in group 1. The mean duration of the hospital stay, the days to oral feeding, the duration of analgesics use and the duration of an indwelling drain were similar between the two groups. The complication rate also did not differ significantly between the two groups(27.6% vs. 23.6%, respectively, p>0.05), and no conversions or re-explorations were required and rectal injury did not occur in group 1. The histopathologic parameters of the two groups were comparable, especially in terms of the surgical margin positivity(37.9% vs. 43.4%, respectively, p>0.05). The continence rate and potency rate were also comparable between the two groups. CONCLUSIONS: Our findings suggest that early outcome of LRP is comparable to that of RRP. Especially the estimated blood loss and the rate of transfusions were lower in the LRP group. We believe that the surgical outcome of LRP will continue to improve at specialized centers as laparoscopic urologists gain experience, and even though an expert laparoscopic urologist may be a naive for prostate cancer surgery, the learning curve is overcome earlier than expected.
