Is Bone Grafting Unnecessary in the Treatment of Cystic Scaphoid Pseudoarthrosis?

PURPOSE OF THE STUDY: The basic aim of the treatment of cystic nonunion is to provide stable fi xation and mechanical compression to increase union, but there is no consensus on whether to perform bone grafting in the cystic area or not. The aim of this study was to compare the clinical and radiological results of patients with cystic scaphoid non-union who received open grafting, and internal fi xation and those treated with percutaneous fi xation without grafting. MATERIAL AND METHODS A retrospective evaluation was made of patients included those determined radiologically with Slade and Dodds grade IV scaphoid cystic non-union. Two different surgical procedures were performed. Percutaneous screw fi xation was carried out on the patients in group 1. Open curettage-grafting and screw fi xation were performed on the patients in group 2. Group 1 was comprised of 16 patients treated with percutaneous screw fi xation, and group 2 was comprised of 17 patients who had open curettage-grafting and screw fi xation. RESULTS In the radiological evaluation at the fi nal follow-up examination, union was determined in 12 of the 16 (75%) patients in group 1 and 15 of the 17 (88%) patients in group 2. There was no statistically signifi cant difference between the two groups in terms of union, functional outcomes and complication rates. DISCUSSION In the current study, the union rate was higher in the patients who had open curettage-grafting and fi xation with a headless screw (88%) than in those with percutaneous screw without grafting (75%), but the difference was not determined to be statistically signifi cant. The union rate of the group that received grafting was similar to the rates reported in the literature. CONCLUSIONS We think that both of these techniques may be successfully used for cystic scaphoid nonunions but percutaneous technique should be preferred as it is minimally invasive. Nevertheless, there is a need for further prospective, randomised studies with larger series to have better comparisons. KEY WORDS: scaphoid bone, nonunion, fracture fi xation, internal, bone grafting, bone screws.

Preparation and Structure of the Ion-Conducting Mixed Molecular Glass Ga2I3.17.

Modern functional glasses have been prepared from a wide range of precursors, combining the benefits of their isotropic disordered structures with the innate functional behavior of their atomic or molecular building blocks. The enhanced ionic conductivity of glasses compared to their crystalline counterparts has attracted considerable interest for their use in solid-state batteries. In this study, we have prepared the mixed molecular glass Ga2I3.17 and investigated the correlations between the local structure, thermal properties, and ionic conductivity. The novel glass displays a glass transition at 60 °C, and its molecular make-up consists of GaI4- tetrahedra, Ga2I62- heteroethane ions, and Ga+ cations. Neutron diffraction was employed to characterize the local structure and coordination geometries within the glass. Raman spectroscopy revealed a strongly localized nonmolecular mode in glassy Ga2I3.17, coinciding with the observation of two relaxation mechanisms below Tg in the AC admittance spectra.

Evaluation of factors affecting treatment and mortality in patients over 65 years of age and without chronic disease, followed in the Intensive Care Unit due to COVID-19.

OBJECTIVE: In this study, demographic, clinical, and laboratory data of patients aged 65 and over who are followed on mechanical ventilators due to COVID-19 in intensive care clinics will be useful in terms of strategies to be developed in the fight against COVID-19 and other infectious agents. PATIENTS AND METHODS: Our study included 299 patients aged 65 years and older, who were not chronically ill, and who were followed up on mechanical ventilators due to COVID-19 in intensive care clinics in the period between 2020 and 2022. Our study was designed as a retrospective cross-sectional study. The demographic characteristics of the patients included in the study, their complaints during hospitalization, the time between the beginning of the complaint and the admission to the hospital, the vital signs at the time of admission to the hospital, the lung computed tomography findings during hospitalization, and the treatments given were examined. RESULTS: 55.9% of all patients were males, and the mean age was 75.45±7.47 years. While there was no significant difference in terms of mean age between the groups of patients with/without a higher risk of mortality, there was a significant difference in gender (p=0.025). There was a statistically significant difference between the COVID-19 intensive care (p=0.001) and renal failure (p=0.014) and mortality groups. The mean nutric score, Procalcitonin (PCT), Lactate Dehydrogenase (LDH), Blood Urea Nitrogen (BUN), Phosphorus, and lactate values, which are important parameters, were statistically higher in the group with a higher risk of mortality (p<0.001). In addition, there was a statistically significant difference in terms of sepsis, neuromuscular blocker (Nmb), vasopressor, and intubation between the groups of patients with/without a higher risk of mortality (p<0.001). In the group with high mortality, 34.2% (n=55) had plasmapheresis treatment, and 14.2% had hemodiafiltration treatment (p<0.001). According to the results of the multivariate logistic regression model in determining the factors associated with a higher risk of mortality, those who were males (p=0.001), those with kidney failure (p<0.001), those with organ failure (p=0.006), increased in alanine aminotransferase (ALT) values (p=0.019), those with sedation (p=0.001) and those with vasopressors (p<0.001) were found to have an increased risk of mortality. CONCLUSIONS: We think that our study is valuable in terms of determining the most appropriate treatment strategies by following the patients in terms of parameters that are significant in the findings during their follow-up period in the Intensive Care Unit.

Is laparoscopic surgery risk for surgical teams during the coronavirus disease pandemic? An in vitro study with a laser and high-speed camera.

OBJECTIVE: Laparoscopic surgery has been suggested to pose a risk of infection to the surgical team due to aerosol and gas leakage during the coronavirus (COVID-19) pandemic. However, there have been no studies on the risk of gas and aerosol leakage in laparoscopic surgery. We aimed to answer the question "Is the aerosol and gas leakage in laparoscopy is hazardous in terms of coronavirus infection?" with this study. MATERIALS AND METHODS: In this study, gas and aerosol leaks were documented by simulating the entry and exit maneuvers from a trocar during laparoscopic surgery using a high-speed camera, fog, and laser in a model representing the abdomen. RESULTS: The maximum gas and aerosol leakage were found during wet gauze extraction from the 10 mm trocar, and its velocity reached 7.5 m/s. The fastest aerosol leakage rate was observed when a 5 mm grasper was extracted from the 5 mm trocar. The results of the subsequent trials were consistent with these values. CONCLUSIONS: Higher leakage speeds were observed than the velocity of the exhaled air in a resting person. The surgical crew members, who work very close to the trocars and each other, are at serious risk of infection with COVID-19 which can spread as fast as exhalation speed through trocars. Since there is an evident risk of infection for the surgical crew from laparoscopic surgery of a patient whose intraabdominal fluids are infected with COVID-19, patients must be evaluated elaborately for COVID-19 preoperatively and infected patients should undergo surgery conventionally.

Reconstruction of proximal pole scaphoid non-union with avascular necrosis using proximal hamate: A four-case series.

Union of proximal pole scaphoid fracture is challenging because the vascular supply is limited. The avascular necrosis accompanying non-union and progressive fragmentation make surgical reconstruction difficult. The present study aimed to report short-term results of reconstruction with proximal hamate in proximal pole scaphoid non-union with avascular necrosis. Four patients (3 male, 1 female) were assessed for non-union following proximal pole scaphoid fracture. Mean age was 25.7 years (range, 22-35 years). Mean interval between injury and reconstruction was 7.5 years (range, 5-9 years). In 3 patients, no treatment was given following the fracture and in the other internal fixation was performed following cast immobilization. The non-united avascular proximal scaphoid was resected and reconstructed with proximal hamate autograft. Mean follow-up was 14.0 months (range, 9-22 months) after reconstruction. At the last control, cases were evaluated in terms of clinical and functional status, and radiologic union was determined on CT scan. Three patients reported subjective decrease in pain. Mean grip strength proportionally to the unaffected side was 24% (range, 8-51%), mean flexion-extension was 55.3% (range, 21-60%), and radial-ulnar deviation was 63.6% (range, 25-100%). Mean QuickDASH score was 32.3 (range, 13.6-52.2). Union was observed in all patients. Proximal hamate reconstruction provided union and pain relief, but only moderate objective functional results. It can be used as an alternative technique in proximal pole scaphoid non-union with avascular necrosis.

Membrane organization of photosystem I complexes in the most abundant phototroph on Earth.

Prochlorococcus is a major contributor to primary production, and globally the most abundant photosynthetic genus of picocyanobacteria because it can adapt to highly stratified low-nutrient conditions that are characteristic of the surface ocean. Here, we examine the structural adaptations of the photosynthetic thylakoid membrane that enable different Prochlorococcus ecotypes to occupy high-light, low-light and nutrient-poor ecological niches. We used atomic force microscopy to image the different photosystem I (PSI) membrane architectures of the MED4 (high-light) Prochlorococcus ecotype grown under high-light and low-light conditions in addition to the MIT9313 (low-light) and SS120 (low-light) Prochlorococcus ecotypes grown under low-light conditions. Mass spectrometry quantified the relative abundance of PSI, photosystem II (PSII) and cytochrome b6f complexes and the various Pcb proteins in the thylakoid membrane. Atomic force microscopy topographs and structural modelling revealed a series of specialized PSI configurations, each adapted to the environmental niche occupied by a particular ecotype. MED4 PSI domains were loosely packed in the thylakoid membrane, whereas PSI in the low-light MIT9313 is organized into a tightly packed pseudo-hexagonal lattice that maximizes harvesting and trapping of light. There are approximately equal levels of PSI and PSII in MED4 and MIT9313, but nearly twofold more PSII than PSI in SS120, which also has a lower content of cytochrome b6f complexes. SS120 has a different tactic to cope with low-light levels, and SS120 thylakoids contained hundreds of closely packed Pcb-PSI supercomplexes that economize on the extra iron and nitrogen required to assemble PSI-only domains. Thus, the abundance and widespread distribution of Prochlorococcus reflect the strategies that various ecotypes employ for adapting to limitations in light and nutrient levels.

Does left molar approach to laryngoscopy make difficult intubation easier than the conventional midline approach?

BACKGROUND AND OBJECTIVE: It has been reported that the left molar approach of laryngoscopy can make difficult intubation easier. The aim of this study was to investigate whether left molar approach to laryngoscopy provided a better laryngeal view in cases of unexpected difficult intubation. METHODS: Following the approval of local Ethics Committee and written informed consent from the patients, out of 1386 patients who underwent general anaesthesia for surgery, 20 patients who could be ventilated by face mask but could not be intubated with conventional midline approach on the first attempt were included in the study. Those 20 patients, who had Grade III-IV laryngeal views on laryngoscopy by conventional midline approach, were subjected to left molar laryngoscopy, and their laryngeal views were evaluated. The external laryngeal compression was routinely used to improve the laryngeal view. When endotracheal intubation failed by left molar laryngoscopy, we performed the conventional midline approach again. All data were recorded. RESULTS: Of the 20 patients studied, 18 had a Grade III laryngeal view and two had a Grade IV laryngeal view. Eighteen of them had a better laryngeal view with left molar laryngoscopy. Eleven of the 20 patients underwent successful intubation with the left molar laryngoscopy, which provided a significantly better laryngeal view and success rate of tracheal intubation than did the conventional midline approach (P < 0.01 and P < 0.01, respectively). CONCLUSIONS: Left molar laryngoscopy can make unexpected difficult intubation easier and should be attempted in cases of difficult intubation.

Patient-controlled analgesia with lornoxicam vs. dipyrone for acute postoperative pain relief after septorhinoplasty: a prospective, randomized, double-blind, placebo-controlled study.

BACKGROUND AND OBJECTIVE: We compared the efficacy of intravenous lornoxicam vs. dipyrone in patient-controlled analgesia for postoperative analgesia. METHODS: The study included 105 patients who had undergone elective septorhinoplasty after receiving general anaesthesia. Patients were divided into three groups to receive lornoxicam (24 mg day(-1)), dipyrone (5 g day(-1)) or placebo. Pain was evaluated using a 0-100 mm visual analogue scale at 2, 4, 6, 8, 12, 16, 20 and 24 h postoperatively. Pethidine (1 mg kg(-1)) was administered intramuscularly to patients requiring rescue analgesia. Pethidine requirements were recorded during the first 24 h postoperatively, and treatment-related adverse effects were noted. RESULTS: Postoperative pain scores were significantly lower with lornoxicam compared with dipyrone at 8 h (P = 0.016). No significant differences regarding pain scores at 2, 4, 6, 12, 16, 20 and 24 h were found. Significantly fewer patients in the lornoxicam group required rescue analgesics (vs. dipyrone, P = 0.046; vs. placebo, P = 0.001); fewer patients in the dipyrone group required rescue analgesics compared with placebo (P = 0.008). Significantly fewer patients in the lornoxicam group had nausea (vs. dipyrone, P = 0.022; vs. placebo, P = 0.006); no significant differences were found between the other two groups. Antiemetic use was significantly lower in the lornoxicam group (vs. dipyrone, P = 0.002; vs. placebo, P = 0.001). CONCLUSIONS: Lornoxicam has better tolerability and is a more effective analgesic than dipyrone when administered by patient-controlled analgesia for postoperative analgesia after septorhinoplasty.

Retropharyngeal submucosal dissection due to nasotracheal intubation.

PROBLEM: Nasal intubation is used often by anaesthetists because it offers many advantages; however, rare complications do arise. A 67-year-old man was admitted to our otorhinolaryngology clinic for uvulopalatopharyngoplasty. Nasotracheal intubation was performed without difficulty. At the beginning of surgery, the surgeon noticed that the nasotracheal tube had penetrated the oropharyngeal mucosa through a channel in the retropharyngeal space. METHODOLOGY: The tube was left in place during surgery to prevent bleeding. After surgery, a vertical incision was made through the mucosa surrounding the tube from the inferior pouch up to the nasopharynx to prevent hematoma. RESULT: The patient was extubated without complication and discharged on the second day postoperative. The oropharyngeal mucosa was healed by the 15th day postoperative. CONCLUSION: Nasal intubation tubes should be lubricated and inserted without force; the oropharynx should be examined carefully after intubation to rule out complications.

A comparison of pre-emptive analgesic efficacy of diflunisal and lornoxicam for postoperative pain management: a prospective, randomized, single-blind, crossover study.

Diflunisal and lornoxicam are currently available non-steroidal anti-inflammatory drugs (NSAIDs) that have been shown to be effective to various degrees in pain relief when administered either pre-emptively or postoperatively. The pre-emptive analgesic efficacy of diflunisal 1000 mg was compared with that of lornoxicam 16 mg in 40 ASA I patients undergoing surgical removal of bilateral impacted third molars. The impacted third molar teeth on one side were removed at the first surgical appointment using one of the two drug regimens being assessed and the teeth on the contralateral side were removed at a second appointment using the alternate drug regimen; all operations were performed by the same surgeon. Acetaminophen up to 2000 mg daily was provided as rescue medication. The postoperative rescue analgesic consumption was recorded and pain scores were evaluated with a visual analogue scale at 2, 4, 6, 12 and 24h postoperatively. No statistically significant differences were found between groups with respect to rescue analgesic consumption and postoperative pain scores. Pre-emptive administration of both NSAIDs proved to be effective in the management of pain following the surgical removal of impacted third molar teeth.

Enhancing biosensor properties of conducting polymers via copolymerization: Synthesis of EDOT-substituted bis(2-pyridylimino)isoindolato-palladium complex and electrochemical sensing of glucose by its copolymerized film.

1,3-Bis(2-pyridylimino)isoindoline derivative bearing 3,4-ethylenedioxythiophene (EDOT-BPI) and its palladium complex (EDOT-PdBPI) were synthesized and characterized by FT-IR, 1H NMR, 13C NMR, UV-Vis spectroscopies and via mass spectrometric analysis. Polymerization of EDOT-PdBPI and copolymerization with 4-amino-N-(2,5-di(thiophene-2-yl)-1H-pyrrol-1-yl)benzamide (HKCN) were carried out by an electrochemical method. In addition, P(EDOT-PdBPI-co-HKCN) modified graphite rod electrode was improved for amperometric glucose sensor based on glucose oxidase (GOx). In this novel biosensor matrix, amino groups in HKCN were used for the enzyme immobilization. On the other hand, EDOT-PdBPI used to mediate the bioelectrocatalytic reaction. Amperometric detection was carried out following oxygen consumption at -0.7V vs. the Ag reference electrode in phosphate buffer (50mM, pH 6.0). The novel biosensor showed a linear amperometric response for glucose within a concentration range of 0.25mM to 2.5mM (LOD: 0.176mM). Amperometric signals at 1mM of glucose were 17.9µA under anaerobic conditions. Amperometric response of the P(EDOT-PdBPI-co-HKCN)/GOx electrode decreased only by 13% within eight weeks. The P(EDOT-PdBPI-co-HKCN)/GOx electrode showed good selectivity in the presence of ethanol and phenol. This result shows that, modification of the proposed biosensor by copolymerization of amine functionalized monomer, which is indispensable to the enzyme immobilization, with palladium complex bearing monomer, which is mediate the bioelectrocatalytic reaction, have provided to give perfect response to different glucose concentrations.

Extension block technique for mallet fractures: a comparison of one and two dorsal pins.

The aim of this study was to compare the clinical and radiological outcomes of one or two dorsal pins for extension blocking of mallet fractures. We treated 36 mallet fractures with the extension block technique. A single pin was used in 19 fractures (Group 1) and two pins in 17 fractures (Group 2). The mean age was 33.6 years and the mean follow-up time was 12.2 months. All patients were assessed by the Crawford outcome score. Extensor lag and other complications were noted. All fractures united with a mean time of 6.0 weeks (4-9) in Group 1, and 6.1 weeks (4-7) in Group 2. We obtained 74% and 71% excellent and good outcome scores in Group 1 and in Group 2, respectively. The final extension lag was 6° in Group 1, and 7° in Group 2. No difference was found between the two groups in terms of clinical outcomes, radiological values and complications.Level 3 non-randomized controlled study.

Inter- and intra-tester reliability of sensibility testing in digital nerve repair.

The aim of this study was to investigate the inter- and intra-tester reliability of the static two-point discrimination and Semmes-Weinstein monofilament tests in digital nerve repair. A total of 100 digital nerves from 67 patients were included into the study. An experienced orthopaedic surgeon and a physiotherapist examined the sensory nerve recovery. The reproducibility score of both tests was at a poor level, but the reliability of the Semmes-Weinstein monofilament test was higher than the static two-point discrimination test. These tests should not be used alone in the quantitative monitoring of sensory recovery, but should be interpreted with the clinical findings.Level 3 non-randomized controlled study.

Characteristics of Patients Who Admitted to the Emergency Department Because of Burns Due to Dens Liquids Such as Hot Milk/Oil.

OBJECTIVE: Burn is the tissue damage on body caused due to various reasons. Although all burns caused by hot liquids are investigated as scalding burns, dense liquid burns (DLB) caused by such as milk and oil are different from other burns. The aim of this study was to report the properties of DLB. MATERIALS AND METHODS: Patients admitted to the Emergency Service of Atatürk University Hospital, with DLB from June 2003 to December 2008, were examined retrospectively. RESULTS: During the study, 28 DLB patients were admitted to the emergency service. The most common admission were found in autumn 28.6% (n=8), and in May and June, 17.9% (n=5). The frequency of burns on the right upper extremity was seen in 50% (n=14) of the patients. The burn degree of all patients was determined as 2(nd) degree. Seventy-five percent (n=21) of the patients were discharged, 14.3% (n=4) were hospitalized. None of the patients died. CONCLUSION: Dense liquid burns is a burn type that is commonly seen in women, absolutely causing 2(nd) degree burns, frequently reported in upper extremity and head/neck regions, and in contrast to other studies, in our region it is completely seen in patients living in city centre.

TEMPO-functionalized zinc phthalocyanine: synthesis, magnetic properties, and its utility for electrochemical sensing of ascorbic acid.

Zinc(ii) phthalocyanine (TEMPO-ZnPc), peripherally functionalized with 2,2,6,6-tetramethyl-1-piperidinyloxy (TEMPO) radicals is synthesized and its magneto structural and electrochemical behaviors are investigated. TEMPO-ZnPc shows multi-electron ring based reduction reactions and a TEMPO based oxidation reaction. Spectroelectrochemical measurements support these peak assignments. TEMPO-ZnPc is tested as a homogeneous and heterogeneous ascorbic acid (AA) sensor. Disappearance of TEMPO-ZnPc based reduction processes and the observation of new waves at around 0 and 1.20 V with respect to increasing AA concentration indicate the interaction of TEMPO-ZnPc with AA and usability of the complex as an electrochemical AA sensor. For practical usage as heterogeneous electrocatalysts for AA sensing, a glassy carbon electrode (GCE) is coated with TEMPO-ZnPc (GCE/TEMPO-ZnPc) and this modified electrode is tested as a heterogeneous AA sensor. The redox peak of GCE/TEMPO-ZnPc at 0.81 V decreases the peak current while a new wave is observed at 0.65 V during the titration of the electrolyte with AA. GCE/TEMPO-ZnPc sense AA with 1.75 × 10(-6) mol dm(-3) LOD with a sensitivity of 1.89 × 10(3) A cm mol(-1).

Single-stage open reduction through a medial approach and innominate osteotomy in developmental dysplasia of the hip.

We treated 15 hips (15 patients) with developmental dysplasia by a single-stage combination of open reduction through a medial approach and innominate osteotomy. The mean age of the patients at the time of operation was 20 months (13 to 30). The mean follow-up period was 9.6 years (4 to 14). At the final follow-up, 14 hips were assessed clinically as excellent and one hip as good. Radiologically, ten hips were rated as class I, four as class II and one as class III according to the criteria of Severin. No avascular necrosis was seen. No patient required subsequent surgery. Our results indicate that satisfactory results can be obtained with the single-stage combination of open reduction by the medial approach and innominate osteotomy for developmental dysplasia of the hip in a selected group of children older than 12 months. To our knowledge, no similar combined technique has been previously reported.

The effect of anesthetic technique on early postoperative renal function after donor nephrectomy: a preliminary report.

General and regional anesthesia may both be used successfully in donor nephrectomy although the use of regional anesthesia is rare. We compared the remaining kidney function during general (n = 10) versus combined spinal-epidural (n = 10) anesthesia for donor surgery. Blood biochemistry data were collected preoperatively and postoperatively, while renal function was assessed by scintigraphy and urine levels of microalbumin, creatinine, Na, K, Ca and creatinine clearance rate were measured/calculated in 24-hour urine samples collected preoperatively and on postoperative day 2. There were no differences preoperatively and on postoperative day 2 with respect to glomerular filtration rate, microalbuminuria, or creatinine clearance rate (P > .05 for all). There were also no differences between the groups with respect to other scintigraphic findings preoperatively and on postoperative day 2 (P > .05 for all). The results suggest that general or combined spinal-epidural anesthesia for donor nephrectomy have similar effects on the remaining donor kidney function.

Partial capitate shortening for Kienböck's disease.

The purpose of this study was to report our experience of partial capitate shortening in seven patients with a median 38 months follow-up. Staging was made by the Lichtman classification system and stage II and III-A patients were included in the study. The mean age was 34 years (range 22-52). Patients were assessed for pain, range of motion, grip and pinch strength, and satisfaction was recorded using a scale between 0 and 4. All these parameters showed improvement after surgery. The Lichtman stage, lunate height index and carpal height index were determined radiographically. Magnetic resonance images of the wrist were studied for lunate revascularization at the final follow-up and occurred in all patients. According to our study, partial capitate shortening seems an effective treatment for Lichtman stage II and III-A patients.Level IV case series study.

Aneurysmal bone cyst of the sternum: a case report of successful treatment with radiotherapy.

An unusual case of a lytic, expanding lesion of the manubrium with histological diagnosis of aneurysmal bone cyst in a 13-year-old girl is presented. After a recurrence following primary surgery, the patient was treated successfully by external beam radiotherapy. A total dose of 25.2 Gy was delivered using conventional fractionation (1.8 Gy day(-1)) to the whole sternum. She remains recurrence- and symptom-free 46 months after the end of the treatment. This is the sixth patient with primary aneurysmal bone cyst in the sternal region, the first paediatric patient for this location, and the first case of its kind treated exclusively by radiotherapy ever reported in the literature. The histopathological, radiological and clinical findings of the patient are presented, relevant literature is reviewed, and radiotherapeutic management of such lesions is discussed.

Regional versus general anesthesia for donor nephrectomy: effects on graft function.

Various general and regional anesthesia methods are used successfully in living-donor kidney transplantation. This study compared kidney graft function after general versus combined spinal-epidural anesthesia for donor nephrectomy. The study groups included recipients who received grafts from donors who had undergone nephrectomy under general anesthesia (GA group; n=10), and recipients who received grafts from donors who had combined spinal-epidural anesthesia (CSE group, n=10). Standard continuous epidural anesthesia was administered during all transplantations. Graft function was assessed using scintigraphy and Doppler ultrasonography on days 3 and 7. Urine levels of microalbumin, creatinine, and creatinine clearance rate were measured/calculated in 24-hour urine samples collected on postoperative days 3 and 7. There were no differences on either day 3 or day 7 with respect to glomerular filtration rate, microalbuminuria, or creatinine clearance rate (P >.05 for all). There were also no differences between the groups with respect to other scintigraphic findings on day 3 or day 7 (P >.05 for all). Ultrasonography on day 7 showed significantly higher mean peak systolic flow in the main renal artery in the CSE group than in the GA group (P=.035). The results suggest that GA and CSE for donor nephrectomy have similar effects on kidney graft function in recipients.
