The right hepatic artery is an end artery and contributes sole arterial supply to right lobe of the liver. Misinterpretation of normal anatomy and anatomical variations of the right hepatic artery contribute to the major intraoperative mishaps and complications in hepatobiliary surgery. The frequency of inadvertent or iatrogenic hepatobiliary vascular injury rises with the event of an aberrant anatomy. This descriptive study was carried out to document the normal anatomy and different variations of right hepatic artery to contribute to existing knowledge of right hepatic artery to improve surgical safety. This study conducted on 60 cadavers revealed aberrant replaced right hepatic artery in 18.3% and aberrant accessory right hepatic artery in 3.4%. Considering the course, the right hepatic artery ran outside Calot's triangle in 5% of cases and caterpillar hump right hepatic artery was seen in 13.3% of cases. The right hepatic artery (normal and aberrant) crossed anteriorly to the common hepatic duct in 8.3% and posteriorly to it in 71.6%. It has posterior relations with the common bile duct in 16.7% while in 3.4% it did not cross the common hepatic duct or common bile duct. The knowledge of such anomalies is important since their awareness will decrease morbidity and help to keep away from a number of surgical complications.

Objective Renal collecting system macroscopically consists of minor calyx, major calyx, renal pelvis and ureter. Stone in renal collecting system is a common presentation in everyday urological practice. The prevalence of renal calculi ranges from 4% to 20% in different geographical distribution. Anatomical variation in renal collecting system plays a significant role in formation of calculi in its parts. The large extra renal pelvis leads to stagnation of urine for longer durations and formation of stones. The stone free rate after percutaneous nephrolithotomy and extra corporeal shock wave lithotomy is significantly related to anatomical factors, particularly the type of renal pelvis and dimensions (length and width) of lower infundibulum. Previous authors described the morphology of pelvicalyceal system in a highly variable manner and the available anatomical description of pelvicalyceal system is contradictory and incomplete. Hence an attempt has been made to provide the precise anatomy of pelvicalyceal system in adult human kidneys. Methods We studied 196 formalin embalmed kidneys to note the number of infundibulum, major and minor calyces. The location and shape of pelvis were also studied. Results The intra-renal pelvis was narrow and had funnel shaped appearance in 95 of total 196 (48.5%) specimens, and the extra-renal pelvis was dilated as balloon shaped in 43 of 196 (21.9%) specimens. In 41 (20.9%) specimens, the renal pelvis was having partially intra- and extra-renal in location. Bilateral symmetry was found in only 27.1% of 196 renal collecting systems. The length of lower infundibulum was more than 22 mm in 19 (9.7%) of 196 cases which directly affects the stone clearance rate during open and endoscopic surgeries on pelvicalyceal system. Conclusion This study provides the accurate morphological details of the shape and dimensions of renal pelvicalyceal system to help the urologists and nephrologists.

Introduction: Cryotherapy is any form of therapeutic application of cold which decreases the temperature of tissues. Objective: To compare the variations in surface temperature of the quadriceps muscle at three different times when exposed to two forms of cryotherapy: ice bags or bags containing a mixture of ice and water. Material and Methods: The study involved 18 subjects, aged between 18 and 25 years, of both sexes. In each volunteer, ice cryotherapy on the left thigh and a mixture of ice and water on the right thigh was simultaneously applied for 15 minutes to the quadriceps femoris region. The temperature was measured by a thermograph and the following moments were recorded: before cryotherapy, immediately and 5 and 30 minutes after removal of the modality of cryotherapy. Results: Both cryotherapy methods were effective to decrease the temperature of the quadriceps and the mixture of ice and water was able to induce a lower temperature compared to the modality which used ice only. The cooling for both modalities lasted for at least 15 minutes after the removal of ice and surface temperature had been restored at pre application 30 minutes after removal. Conclusion: Both methods promoted a reduction in temperature that lasted at least 15 minutes, and 30 minutes after the with drawal the temperature was reestablished to normal levels. However, the mixture of ice and water produced cooling more remarkable than the ice alone.
