Calculous anuria is one of the complications of upper urinary tract calculi and may be caused by mechanical obstruction at some point of the tract, renal insufficiency, and a combination of obstructive and renal factors. The clinical features may vary from a complete absence of symptom to the time when the patient observes he could not pass urine. An immediate roentgenogram and catheterization of the ureters in an attempt to restore the excretion of urine are always recommended and in from 50 to 55 per cent of the patients the calculus is expelled. Even if anuria recurs after withdrawal of the catheter, the patient is in better condition for surgical intervention as a result of the removal of accumulated nitrogenous waste products. Uric acid calculi comprise from 3.5 to 4 percent of urinary calculi. A low purine diet, allopurinol and alkalinization of urine are proved very effective in management of it. Recently we have experienced a case of calculous anuria due to bilateral ureteral stones in 41 years old man and present it with the review of the literatures.

니켈-크롬 합금과 Porcelain laminate의 결합력에 관한 연구
이승로,진태호,동진근,Lee Seung-Lo,Jin Tai-Ho,Dong Jin-Keun 대한치과보철학회 1992 대한치과보철학회지 Vol.30 No.1
The purpose of this study was to evaluate the bonding strength between porcelain laminate and Ni-Cr alloy in the various surface treatments of the bonding faces. For this study the metal surface of specimens were treated : 1) etching only, 2) sandblasting only, and 3) sandblasting and etching. The porcelain laminate were made and bonded to the metal specimens with light curing composite resin cement. Instron testing machine was used to measure their bonding strength : and the result was obtained as follows : 1. The bonding strength of the double treatment of the sandblasting and etching group was higher than that of the single treatment of sandblasting or the etching group. 2. The bonding strength of the sand blasting group was higher than that of the etching group. 3. The debonding were mainly occurred between the Ni-Cr alloy and the composite resin cement.

Stroke 환자의 말명료도에 영향을 주는 우리 말소리 연구
이승로,김숙희 국제다문화의사소통학회 2015 다문화의사소통 Vol.4 No.-
말운동장애는 명료도의 문제를 가지고 있기 때문에 우리말의 어떤 말소리와 가장 민감하고 관련이 있 는지를 알아 보고자 하였다. 14명(남 8명, 여 6명)의 마비말장애의 평 균 연령은 53.26(± 6.89)이었고, 정상군은 51.67(± 2.35)이었다. 연구결 과 첫 번째, 기식음과 VOT와의 관련이 높게 나타났음며, 둘번째, SPL 과 성문저항 분석에서도 모두 기식음에서만 유의미한 차이를 보이고 있어 낮은 성문저항은 음의 강도를 증가시킴에도 불구하고 구강압력의 형성의 실패로 명료도에 영향을 주는 것으로 나타났다. 따라서 우리말 의 기식음이 신경학적 말운동장 환자의 명료도와 관련이 있는 것으로 나타났다. In order to execute speech, basically, phonation and proper speech is produced by the function of various methods and sequences of articulators and coordination among valve and structures or airflow generation. As a result, the following conclusions were reached. First, according to the result of study on coordination of superior larynx system, it was shown that VOT, the temporal coordination parameter of superior larynx system, was proportional to the level of aspiration, and an evidence for propriety was provided according to phonation type, rather than articulation place. Finally, a problem with adductor according to the incoordination or weakness of intrinsic laryngeal muscle in neurological speech disorder had an effect on aspiration.

Stroke 환자의 발성시 기류의 효율성에 대한 비교 연구
이승로 국제다문화의사소통학회 2020 국제다문화의사소통학회 학술대회 Vol.2020 No.6
본 연구의 목적은 stroke 환자의 말소리를 공기역학적으로 변별하기 위한 음향학적, 기류적 파라미터들 을 측정하여 말소리에 영향을 줄 수 있는 강도와 기류율, 성대진동과 성문기류사이 관계를 분석하는 동시에 성문하압을 음향학적 에너지로 변환시키는 후두 능력 척도인 발성효율성(vocal efficiency)을 알 아봄으로써 공기역학적 측면에서 변별 정도를 제시 할 수 있는 근거내지는 단서로 활용하여 stroke 환 자의 전반적인 명료도를 연구하는데 기초적 자료로 활용하여 말메커니즘의 기능적 측면과 유기적인 상 호작용을 이해하는데 도움을 주고자 하였다.

3차원 전산화단층촬영 혈관조영술(3D-CTA)을 이용한 뇌동맥류의 진단
이승로 한양대학교 의과대학 1999 한양의대 학술지 Vol.19 No.2
In contrast to the cerebral angiography, 3D-CTA is a noninvasive diagnostic method with high-speed volumetric data acquisition and this permits fast images in adequate quality without significant complications. The ability of multiplanar reconstruction and three dimensional display from different angles of 3D-CTA enables us to form useful information about the aneurysm itself in terms of shape, direction, neck, lumen and adjacent structures including vessels that helps in the planning of surgical treatment. Although 3D-CTA is as sensitive as cerebral angiography in detecting aneurysm with larger than 3mm, smaller aneurysms or aneurysms located near skull base may fail to demonstrate with 3D-CTA. Some limitations as small field of view, not shown flow dynamics, misregistration and artifact may lead misdiagnosis and need for cerebral angiography. Improvement of hardware and image reconstruction method of 3D-CTA such as Multi-Angle Reconstruction Plan (MARP) and Local Maximum Intensity Projection (LMIP) could advance anatomic detail and permit larger field of view with shorter scanning time. Therefore 3D-CTA may replace cerebral angiography in the near future.

자발성 흉부 척수 탈출증은 척수가 손상이나 수술적 조작의 기왕력이 없는 경막을 통해 탈출 되는 드문 질환이다.이 질환은 척수병증을 유발하는 질환 중에서 치료가 가능한 경우이나 잘 알려져 있지 않은 질환이므로 적절한 진단이 늦어지는 경우가 많다.저자들은 CT와 MR소견상 흉부 척수가 경막 결손을 통해 전측방으로 탈출되어 있었던 자발적 흉부 척수 탈출증의 증례를 경험하여 보고한다. Spontaneous herniation of the spinal cord is a rare disease entity in which spinal cord substance is herniated through a previously uninjured and/or untouched dura. It is a cause of myelopathy that is treatable but difficult to diagnose. We report the CT and MR findings of a case of spontaneous thoracic spinal cord herniation manifesting as ventrolateral protrusion of thoracic spinal cord through a dural defect.
