The evaluation of urinary calculi was done in 84 patients of paraplegia and quadriplegia due to traumatic spinal cord injury. These patients were diagnosed by KUB and intravenous urography at National Veterans Hospital during 6 years from Jan. 1975 to Dec. 1980. The results were as follows; 1. Overall incidence of urinary calculi was 38.1 %; Incidence of renal calculi was 8.3%, ureteral calculi 4.8%, and urinary bladder claculi 32.1%. 2.Relation of neurological level and incidence of urinary calculi were as follows; Cervical injury in 34.8% upper thoracic injury in 40.0%, lower thoracic injury in 45.0%, and lumbar injury in 36.5%. 3. Laterality was not toplay a role information of urinary claculi. 4. The urinary calculi were developed 62.5% during the first 36 months following spinal cord injury. 5. The recurrence of urinary calculi was 40.6%; True recurrence was 15.6% and pseudo recurrence was 25.05.

PURPOSE: Nitric oxide synthase(NOS) is an important enzyme in the production of nitric oxide(NO). The constitutive type(cNOS) is expressed in the normal physiologic state, and the inducible type(iNOS) in expressed in the active immune state. cNOS is divided into an endothelial type (eNOS) and a neuronal type(nNOS). eNOS affects blood vessels, while nNOS affects nerve fibers. In the present study, we evaluated the expression of eNOS and nNOS in rat bladders with short-term partial outlet obstructions. We presupposed that NO is responsible for prolonged micturition problems after partial outlet obstruction. MATERIALS AND METHODS: Specific pathogen-free Sprague-Dawley rats weighing 250-300g were used for the study. Individual bladders were obtained from sham-operated control rats(n=5) and from experimental rats at 12 hours and 1, 2, 3, and 7 days after partial urethral obstruction(n=25). eNOS and nNOS were detected using immunochemical staining and analyzed with confocal microscopy and an image analyzer. RESULTS: eNOS and nNOS expression were detected in both the control group and in the group with partial outlet obstruction. The expression of eNOS showed a sharp increase at 3 days after obstruction and returned to normal at 7 days. The expression of nNOS was not significantly different between the two groups. CONCLUSIONS: In this study, we showed that eNOS increases in the rat bladder after partial outlet obstruction. This finding suggests that overproduction of NO may be the result of ischemic injury sustained during partial bladder outlet obstruction.

PURPOSE: Benign prostatic hyperplasia (BPH) with prostatitis is a common clinical problem. There have been no previous reports of the effect of pathologic prostatitis on the improvement of lower urinary tract symptoms (LUTS) preceded by transurethral resection of prostate (TURP). Therefore, the purpose of this study was to determine the effect of pathologic prostatitis on improvement of LUTS after TURP. MATERIALS AND METHODS: From March 1996 to December 2006, 237 patients who received TURP were divided into two groups of with mild or severe pathologic prostatitis according to the pathological results of prostate tissue evaluation, International Prostate Symptom Score (IPSS), quality of life (QoL), maximum flow rate (Qmax) and the development of complications were recorded before and at 3 months follow up after surgery. RESULTS: No statistically significant differences were identified in the two groups with regard to Qmax, resection rate and complications (p>0.05). However, the IPSS and QoL were significantly different in comparisons between the two groups (p<0.05). CONCLUSIONS: Therefore, the results of this study show that BPH accompanied by pathologic prostatitis affects the improvement of LUTS, after TURP, and treatment of prostatitis may increase patients' satisfaction after surgery.

Gastric mucosa-associated lymphoid tissue (MALT) lymphoma is a low-grade lymphoma with a long median survival time because of its low proliferation rate. A 75-year-old man was referred to the hospital for hematemesis. Upper endoscopy revealed a 30-mm subepithelial tumor (SET). Abdominal CT and EUS revealed a homogeneously hypoechoic lesion arising from the second layer of the stomach, without distant metastasis. Laparoscopic wedge resection was performed. On microscopic examination, the tumor showed diffuse aggregation of small lymphoid cells with abnormal architecture. Neoplastic cells showed positive reactivity for CD20 and prominent lymphoepithelial lesions were observed. The urease breath test was also conducted, with a negative result. Our final diagnosis was Helicobacter pylori-negative MALT lymphoma (Ann Arbor classification IE2), which is a rapidly growing SET pattern. This case highlights the importance of including gastric MALT lymphoma as a differential diagnosis for rapidly growing gastric SETs.

Membranoproliferative glomerulonephritis(MPGN) is a morphologic entity and characterized by several pathologic feature. MPGN is classified into a primary (or idiopathic) and secondary forms. We report a case of type I MPGN associated with cellulitis on pathologic feature. MPGN is classified into a primary (or idiopathic) and secondary forms. We report a case of type I MPGN associated with cellulitis on lower leg. He was admitted due to ingrowing nail complicated by surrounding cellulitis and edema. Chraracteristically, hematuria and proteinuria(3.2gm/ day) were noted. We couldn't find any secondary causes', ANA, cryoglobulin, HBs Ag and RA factor were negative. Renal pathologic findings showed double-contoured basement membrane, electron-dense material infiltration and mesangial proliferation. This findings were concordant with type I MPGN and we treated with antibiotics and supportive care. During follow-up, skin lesion, proteinuria and hematuria were resolved and he readmitted in purpose of control renal biopsy, We observed resolution of previous abnormal findings other than mesangial proliferation. This case was considered as type I MPGN associated with cellulitis on lower leg.

Although the most of mushroom poisoning have a clinical menifestation of mild to moderate gastroenteritis, some mushroom may cause a serious illness; acute renal failure, hepatic necrosis. We experienced two cases of acute renal failure complicated by the poisoning of amanita virosa. Amanita virosa have a amatoxin. Amatoxin deteriorate hepatocytes, renal tubular cells, intestinal mucosal cells, and pancreas. They were transferred from local hospital for renal failure management. On admission, blood urea nitrogen and serum creatinine were highly elevated. We diagnosed acute renal failure complicated by poisoning of amanita virosa. In one case, renal function was further deteriorated compared with initial laboratory findings after creatinine was normalized at fifth day. Thus, we did a kidney biopsy. Light microscopy and EM showed interstitial inflammation and moderate tubular atrophy. They were recovered with the supportive management. We report two cases of mushroom poisoning-induced acute renal failure with review of literature.

Aminoglycoside has a broad-spectrum bactericidal activity and especially excellent effect on gram negative bacteria. But, its harmful effect is existed about kidney and ear. Among these, many studies were done about aminoglycoside nephrotoxicity. Until now, many authors have been reported its incidence was 4.45-45%. We needed parameters monitoring about nephrotoxicity. So, our study was done using 99mTc-DTPA renal scan to evaluate nephrotoxicity. We enrolled forty patients who admitted due to infection. 32 patients received Netilmicin and 8 patients Isepamicin. Mean duration and dosage were 8 days, 200mg daily. We accomplished 99mTc-DTPA renal scan, 24hr urine study and blood sampling before starting antibiotics. After mean 8 days, same procedure was repeated. Aminoglycoside nephrotoxicity(defined as 50% GFR reduction) was presented in only one patient. She didn't have risky factor, such as hepatic dysfunction, hypotension, previous renal problem. However, duration was longer than other patients(13 days). GFR was fallen by 25-50% in 6 patients. This finding represent nephrotoxic effects of aminoglycoside indirectly. Above 6 patients had not any characteristics compared to other 33 patients. In addition to renal scan, sodium excretion was increased compared to pre-antibiotics, and glomerular filtration rate using 99mTc-DTPA renal scan was positively correlated with 24hr urine creatinine clearance, GFR by Cockcroft & Gault equation. I conclude that aminoglycoside has nephrotoxic effect when used for longer period. Thus, I suggest that DTPA renal scan including other many renal monitoring method has usefulness in revealing aminoglycoside nephrotoxicity.

BACKGROUND: Pulmonary tuberculosis (TB) is still common disease among the elderly patients in Korea where the overall incidence of TB is decreasing. Adverse drug reactions (ADR) associated with anti-TB drugs occurs frequently. Especially the aged tends to have more frequent ADRs than younger ones. These ADRs can cause significant morbidity, compromise therapeutic effects of drugs and even induce drug resistance. Therefore we evaluated the effect of ADRs on the first-line anti-TB drugs in elderly patients with active pulmonary TB. METHODS: We retrospectively reviewed the charts and radiological findings of the patients with 65 and older who were bacteriologically confirmed as active TB and treated with standard anti-TB drugs for at least 6 months. Major ADR was defined with temporary or continuous stop of any first-line drugs intake. RESULTS: An ADR was noted in 54% of all patients. The incidence of major ADR was 32% in all elderly patients. Dermatologic ADR (9%) was the most common among the major ADRs. GI trouble (8%), arthralgia (6%), visual change (6%), hepatotoxicity (4%), and fever (1%) were also noted. The drugs responsible for major ADR were ethambutol (62%), pyrazinamide (35%), rifampin (18%) and isoniazid (9%). Major ADRs were associated with higher ESR level at the initiation of anti-TB drugs. CONCLUSION: First-line anti-TB drugs in elderly patients frequently caused the major ADRs. Therefore the elderly patients receiving anti-TB drugs should be closely monitored and better tolerable therapy should be considered as part of a TB research agenda.

Immunoglobulin G4-related sclerosing disease is a novel clinicopathological disease entity known to involve various organs including the pancreas, bile ducts, gall bladder, retroperitoneum, kidney, salivary gland, lung and prostate. The most common organ involved is the pancreas and cases without pancreatic involvement are uncommon. Positive response to steroids is an important characteristic of this disease and this enables early diagnosis, which is required for good prognosis. We demonstrate a case of immunoglobulin G4-related tubulointerstitial nephritis in a 59-year-old male accompanied by sclerosing cholangitis and sialadenitis without any evidence of pancreatic infiltration. The patient was treated with prednisolone and was fully recovered in 6 months.
