Item Study of Variations In Superior Segmental Branch of Renal Artery.(2014-10) Chandragirish, S; Nanjaiah, C M; Shirur, Suhas Y; Saheb, Shaik HussainBackground: Based on vascular divisions the renal tissue divided into five segments that are apical, anterior superior, anterior inferior, inferior and posterior. The apical segment occupies the antero medial region of the superior pole. The superior segment includes the rest of the superior pole and the central antero-superior region. The segmental arteries of the kidney supply the organ in such a way that, each renal pole receives its own artery while, the anterior portion between the poles is supplied by an upper and lower segmental vessel. The present study concentrated on variation of superior segmental artery which is help in nephrology clinical practice. Materials andMethods: Fifty pairs of kidneys with intact abdominal aorta and renal artery were collected from the dead bodies obtained from themortuary of Forensic department, JSSMedical College andMysore Medical College and studied in JSS Medical College. For study of segmental variation Corrosion cast technique method was used. Results: In present study type I superior segmental artery were found in 28%, type II in 12%, type III in 14%, type IV 20%, type V in 1% o and type VI 23% of cases. Conclusions:We observed variations in superior segmental branch of renal artery in 100 kidneys and observed 6 types of variation. These knowledge of vascular segments of kidney helpful for the clinician to do renal transplantation interventional radiological procedures.Item Study on Accessory Renal Artery.(2014-10) Chandragirish, S; Nanjaiah, C M; Shirur, Suhas Y; Saheb, Shaik HussainBackground: Knowledge of the variations of renal vascular anatomy has importance in exploration and treatment of renal trauma, renal transplantation, renovascular hypertension, renal artery embolization, angioplasty. The anomalies of accessory renal artery may be important from the clinical point of view. The importance of being familiar with the renal artery and segmental artery variability, which has become indispensable to urological surgery, has increased as a result of the large number of renal transplants and vascular reconstructions. Materials and Methods: 100 kidneys (Fifty pairs) intact with abdominal aorta were collected from department of Forensic department, JSS Medical College and Mysore Medical College. For study of segmental variation Corrosion cast technique method was used. The variations of posterior division were observed and recorded. Results: Accessory renal arteries were found in two specimens originating directly from aorta out of 100 specimens, it is recorded as 2%. Conclusion: In present study we observed 2% of cases as accessory renal artery. The recent days the increasing demand for kidney transplantation, grafts from living donor is major source for that, with this concept the knowledge of accessory renal artery very essential for kidney transplantation.Item Study on Variations of Anterior Division of Renal Artery.(2014-10) Chandragirish, S; Nanjaiah, C M; Shirur, Suhas Y; Saheb, Shaik HussainBack ground: Urinary System is one of most important system among many systems in our body the most common variations in case of circulatory system usually occur in form of origin, number, length, and diameter. Based on divisions of renal artery, the renal parenchyma is divided into five segments: apical, anterior superior, anterior inferior, inferior and posterior. The main renal artery divides initially into an anterior and posterior branch. The anterior branch almost always supplies the upper, middle and lower segments of the kidney. Materials andMethods: Fifty pairs of kidneys with intact abdominal aorta and renal artery were collected from the dead bodies obtained from themortuary of Forensic department, JSSMedical College andMysore Medical College and studied in JSS Medical College. For study of segmental variation corrosion cast technique method was used. Results: In present study type I anterior division of renal artery were found in 31%, type II in 19%, type III in 8%, type IV 20% and type V in 16% of cases. Conclusion: We observed variations in anterior division of renal artery in 100 kidneys and observed 5 types of variation. These variations are helpful for the surgeon performing major surgeries like kidney transplant and partial nephrectomy.Item Study on Variations of Anterior Inferior Segmental Branch of Renal Artery.(2014-10) Chandragirish, S; Nanjaiah, C M; ShirurSuhas, Y; Saheb, Shaik HussainBackground: The kidneys are paired solid organs that lie in the retro peritoneum along the borders of psoas muscle. Each kidney is positioned obliquely and awareness of the relationship of the kidneys to the surrounding organs is paramount. Each kidney is supplied by a renal artery, which is a branch of the abdominal aorta, the branching pattern of renal artery shows very much variations , the knowledge of individual segmental artery variation are very helpful for clinical practices of renal surgeries. Materials andMethods: Fifty pairs of kidneys with intact abdominal aorta and renal artery were collected from the dead bodies obtained from themortuary of Forensic department, JSSMedical College andMysore Medical College and studied in JSS Medical College. For study of segmental variation Corrosion cast technique method was used. Results: In present study type I anterior inferior segmental artery were found in 47%, type II in 16%, type III in 24%, type IV 10%, type V in 0% o and type VI 1% of cases. Conclusion: The variation of the anterior inferior segmental artery has not been given importance in previous works and they have been typed (6 types) in the present work. The knowledge of anterior inferior segmental artery variations are helpful in renal surgeries in particular with anterior inferior segmental artery distribution area.Item Study on Variations of Inferior Segmental Branch of Renal Artery.(2014-10) Chandragirish, S; Nanjaiah, C M; Shirur, Suhas Y; Saheb, Shaik HussainBackground: The segmental arteries of the kidney supply the organ in such away that, each renal pole receives its own arterywhile, the anterior portion between the poles is supplied by an upper and lower segmental vessel. These two arteries also include in their territory the lateral edge of the kidney and adjacent to the strip of parenchyma on the dorsal or posterior aspect of the organ. The knowledge of inferior segmental branch of renal artery is very important for surgeries in its distribution area in kidney. Materials and Methods: 100 kidneys (Fifty pairs) intact with abdominal aorta were collected from department of Forensic medicine, JSS Medical College and Mysore Medical College. For study of segmental variation Corrosion cast technique method was used. The variations of inferior segmental branch of renal artery were observed and recorded. Results: In present study type I inferior segmental branch of renal artery were found in - 59% cases, type II in - 6% cases, type III in - 28% cases, type IV in - 2% cases. Conclusion: The inferior segmental artery from the anterior division of the renal artery is the commonest event –arising in 59%. This is Type I, the normal type. It arises from the renal artery (28%) or from the posterior division (6%) or from the aorta (2%). The knowledge of inferior segmental branch of renal artery helpful in kidney transplantation and renal surgery because these type of surgeries success mainly depends on arterial ligations.Item Study on Variations of Posterior Division of Renal Artery.(2014-10) Chandragirish, S; Nanjaiah, C M; Shirur, Suhas Y; Saheb, Shaik HussainBackground: Kidney transplantation is the treatment of choice for the vast majority of patients with end stage renal disease. Many of the current challenges with the donor grafts are the results of anatomic variants, such as multiple renal arteries, multiple. The previous studies have shown that use of vessel grafts is associated with a higher incidence of vascular and urologic complications. With this back ground the knowledge of variations in vascular pattern is very helpful for renal transplantation and renal surgeries. Materials and Methods: 100 kidneys (Fifty pairs) intact with abdominal aorta were collected from department of Forensic department, JSS Medical College and Mysore Medical College. For study of segmental variation Corrosion cast technique method was used. The variations of posterior division were observed and recorded. Results: In present study type I posterior division of renal artery were found in - 27% cases, type II in - 42% cases, type III in - 25% cases. Conclusion: In present studywe found three types of posterior division of renal artery this knowledge helpful in treatment of renal trauma, renal transplantation, renovascular hypertension, renal artery embolization, vascular reconstruction.
