BackgroundThe use of grafts with multiple renal arteries has been considered a relative contraindication because of the increased incidence of vascular and urologic complications The aim of this study is to determine whether the kidney grafts with multiple arteries have any adverse effect upon post-transplant graft and patient survival.MethodsWe reviewed the records of 225 adult kidney transplants done consecutively at our institution. Twenty-nine patients (12.8%) had grafts with multiple renal arteries. We analyzed the incidence of post-transplant hypertension and vascular complications, mean creatinine levels, patient and graft survival. In 17 cases reconstruction was done as conjoined anastomosis between two arteries of equal size, and in 6 cases as end-to-side anastomosis of smaller arteries to larger arteries. Multiple anastomoses were performed in 6 cases.ResultsIn one patient postoperative bleeding occurred. Mean systolic blood pressures, creatinine levels at first year and last follow-up and complication rates were all in acceptable ranges. There was no significant difference in graft and patient survival between multiple and single renal artery allografts.ConclusionAlthough the kidney grafts with multiple renal arteries have been considered a relative contraindication because of the increased risk of complications, in our study allografts with multiple arteries were used successfully in kidney transplantation.

Soft contact lenses and rigid gas-permeable contact lenses cause corneal thickening and corneal flattening in the first months, but they cause corneal thinning and corneal steepening with time. These alterations can be evaluated as evidence that contact lenses negatively influence corneal physiology.

Purpose: Aim of this study was to report our experience in elective and emergency surgery on chronic hemodialysis (CH) patients for end-stage renal disease (ESRD). Methods: All patients on CH for ESRD who underwent various surgical procedures in our unit within the past 9-year period (2001)(2002)(2003)(2004)(2005)(2006)(2007)(2008)(2009)(2010) were included in this study. These patients were divided into two groups according to the type of surgery performed: elective or emergency. Demographic data, indications for surgery, primary causes of ESRD, surgical procedures, postoperative complications, and mortality rates were studied. Results: Of 130 patients, 121 underwent elective surgery while 10 were addressed for emergency operation. In the elective surgery group, the most common diseases were secondary hyperparathyroidism, kidney diseases, cholelithiasis, and diabetic foot gangrene. Complications occurred in nine patients (morbidity rate, 7%) and only one patient died (mortality rate, 0.8%). In the emergency surgery group, the most common diseases were diabetic foot gangrene and obstructed sigmoid colon cancer. In this group, complications occurred in seven patients (total morbidity rate, 70%) and two patients died (mortality rate, 20%). Conclusions: Elective surgery in patients on CH for ESRD can be performed with acceptable surgical risks provided careful preoperative preparation, intraoperative, and postoperative precautions are taken.
