Acupuncture with gold needle insertion is utilized in Oriental medicine, and the effect of therapy is represented by anti-inflammatory and analgesic function, But sometimes the needle is erroneously inserted into abdominal organs, and then it may cause dangerous complications. We report a case of multiple gold needles in the abdominal organs without having definete clinical symptoms.

4.Early Clinical Experience of Interstitial Laser Coagulation(ILC) for the Treatment of Benign Prostatic Hyperplasia.
Korean Journal of Urology 1999;40(2):201-206
PURPOSE: Variable modalities, with more comfortable and less incidence of post-operative complications over TURP, have been used for the treatment of benign prostatic hyperplasia(BPH) with bladder outlet obstruction. Recently, we performed Interstitial Laser Coagulation(ILC) with the 830nm diode laser, which is considered as a method of minimally invasive treatments for BPH, to assess the efficacy and safety of the device, and to evaluate its capability of replacing TURP for managing BPH. MATERIALS AND METHODS: We analysed 16 patients, who had suffered from symptomatic BPH, treated with ILC using diode laser retrospectively from April 1996 to January 1997. Mean age of the patients was 71.7(52-84) years old and mean size of prostates before the treatments was 52.2(26.8-100.7)gm. Treatment outcome was estimated by comparing IPSS, QOL, Qmax, Qave and residual urine before the operations with them of first and second month after the operations. Post-operative transrectal ultrasonography was able to several cooperative cases and they were compared with them of pre-operative volumes, too, although it was unavailable to evaluate statistically. RESULTS: The operation were performed under epidural or spinal anesthesia with average time of 62 minutes and with 10 days of post-operative catheterization. IPSS reduced from 22.25(+/-4.82), mean value before the operation, to 11.00(+/-5.58) and 5.00(+/-3.10) at first and second month after ILC. QOL was gradually decreased from 4.44(+/-0.51) to 2.31(+/-1.20) and 1.19(+/-0.91), too. In terms of Qmax, mean was 12.29(+/-5.55)ml/sec before the operation and it was increased to 15.94(+/-7.38)ml/sec and 20.75(+/-8.48)ml/sec. Average flow rate was also increased from 6.98(+/-2.05)ml/sec to 10.38(+/-3.72)ml/sec and 14.93(+/-4.37)ml/sec. Significant reduction was observed in residual urine volume from 98.13(+/-91.72)ml to 33.19(+/-36.58)ml and 9.56(+/-11.24)ml respectively. Minimal hematuria and mild bladder irritations were common symptoms after the procedure, and possible significant complications as like anemia, electrolyte imbalance(post-TUR syndrome), epididymoorchitis, erectile dysfunction, urethral stricture, retrograde ejaculation had not found in our experience, but 1 patient was retreated with TURP because of continued bladder outlet obstruction. CONCLUSIONS: Our initial results with ILC showed that it is a relatively simple and minimally invasive method with minimal occurrence of bleeding and no electrolyte imbalance. We concluded that ILC is a safe and efficacious treatment modality, and it can be used even for elder patients with co-morbidity illness as well as patients with too large prostate to perform TURP.

Perigraft seroma is uncommon complication of polytetrafluoroethylene(PTFE) grafts applied as an arteriovenous shunt for hemodialysis. It is a collection of clear, sterile fluid confined to nonsecretory fibrous pseudomembrane, most commonly localized around the middle and distal portion of graft. The possible etiologic factors of perigraft seroma include poor graft incorporation, mechanical graft damage caused by alcohol and povidone-iodine, intraoperative streching of the graft, variations in quality control at the time of manufacture and contributing factors such as anemia and coagulopathy in uremia. The best strategy for management of perigraft seroma is not clear. spiration or drainage alone is not effective, and some authors advocate graft removal. We report a case of perigraft seroma around arterial end of PTFE graft along with a brief review of the literatures.

PURPOSE: The aim of this study was to assess the mid-term results of primary cementless total hip arthroplasty (THA) using Summit® stems. MATERIALS AND METHODS: One hundred twenty-eight arthroplasties in 121 patients who were performed THA from December 2004 to March 2013, were reviewed retrospectively a minimum of 4 years follow-up (mean age, 60.3 years; mean postoperative follow up period, 86.3 months). For a clinical evaluation, the Harris hip score (HHS) was used to assess outcome. Radiographic evaluation was done through spot welds, subsidence, stress shielding, canal filling. RESULTS: The mean HHS was 69.8 points preoperatively, and it improved significantly to 96.3 points at the final follow-up. Postoperatively, 10 patients experienced thigh pain and 7 patients showed a moderate limping gait. There was not only early stem subsidence but there was no more subsidence at last follow up. One hundred eighteen hips showed radiographic signs of stem bone ingrowth, and 10 hips showed fibrous ingrowth at the last follow-up. Stress shielding occurred in 85 hips and third degree stress shielding was observed in 6 hips. Complication arose in 10 hips due to dislocation. Although revisions due to recurrent dislocations led to acetabular component revision in one hip, no revisions arose due to isolated aseptic loosening of the femoral component. CONCLUSION: The clinical and radiological mid-term results of primary THA using Summit® stems revealed solid initial fixation and bone ingrowth stable fixation. Considering the satisfactory clinical results, Summit® stems may be a good treatment option in Korean patients who were required hip arthroplasty

We present one case report of anterior urethral diverticulum in a male with giant calculi. The patient was a 56-year-old male with the complaints of base-ball sized palpable scrotal mass and post-void dribbling for 15-16 years. The diverticulum was filled with multiple whitish-yellow stones. The largest one was 8X7X6cm in size.

Even though the value of computed tomography (CT) used to detect the colon carcinoma with minimal invasion is limited, its usefulnes sin the evaluation of the extent of disease such as hepatic metastasis or distant lymph node invasion has been emphasized. To examine the role of CT in the evaluation of colon carcinoma, CT scans obtained during the past 2 years in 56 patients with surgically proven colon carcinoma were reviewed and the findings correlated with pathologic results. The sensitivity and accuracy of CT for pericolic fat infiltration were 86, 58 and 80% respectively. Those of regional node were 60, 83 and 75% and distant node 67, 100 and 95%. Liver metastases showed sensitivity, specificity and accuracy of 83, 98, 96% and peritoneal metastases 67, 94 and 89% respectively. CT detected local invasion with fair degree of accuracy but the true value of CT lie in the detection of distant invasions such as liver and distant lymph node metastases thereby leading to preclusion of unnecessary procedures and implementation of appropriate precedures.

Foreign bodies in the genitourinary tract are relatively common, and almost of them are discovered within the bladder. We had experienced a patient and report herein, who had a plastic tube in the bladder, introduced through urethra during masturbation. The size of the tube was 110cm in length and 0.5cm in diameter, and it was easily diagnosed by history, symptoms, simple KUB, cystoscopy, and was removed by foreign body forceps under the cystoscopy.

PURPOSE: We report seven cases of pancreas transplantation, first performed in Korea, in the context of postsurgical radiologic studies. MATERIALS AND METHODS: All patients with insulin-dependent diabetes mellitus received transplants from cadevaric(n=6) or living related donor(n=1). Retrospective analysis of 27 US(including 19 Duplex US), two CT, four MRi, and three scintigraphy for these patients was made with surgico-pathological correlation in five cases. RESULT:Of the seven patients, three-month graft survival was five and one-year survival was two. One patient died of abdominal abscess following surgery. US gave the valuable informations regarding the graff swelling, vascular complication, and perigraff fluid collection. RBC bleeding scan was effective of the presence or absence and location of intestinal bleeding. CT was useful in determining the extent and severity of the pancreatitis. MRI gave a little information about functional status of the grafted pancreas. CONCLUSION: The choice of appropriate imaging modalities for postsurgical work up in patients who had pacreas transplantation depends on the clinical conditions of the patients and complications suspected. Further prospective studies appear to be necessary to eatablish the interval and modality choice for early detection of the complication.
