Abstract [en]

Background: We sought to study gender differences and differences over time with respect to demographics, relation to recipient,donor motives, and experiences of live kidney donation.

Material/Methods: In all, 455 consecutive live kidney donors, representing all of the donors at our center between 1974 and 2008were considered for this study. There were 28 deceased donors and 14 donors who had moved abroad, leaving413 donors; 387 (94%) agreed to participate in this study. A questionnaire was sent and the answers wasanalyzed for gender differences and, where relevant, for changes over time.

Results: In all sub-periods, female donors made up the majority (55–62%), except for sibling donors (45%) and childto-parent donors (40%). No significant gender differences were seen in perceived information given before donation.For males, it was more common that the recipient took the initiative to donate. For females, the motivationfor donating was more frequently to help the recipient and because others wanted them to donate.For males, it was more common to feel a moral obligation. Post-operatively, females more frequently felt sad and experienced nausea, and more frequently felt that the donation had a positive impact on their lifes. With the introduction of minimally invasive surgical techniques, donors experienced fewer problems from the operation, with no gender difference.

Conclusions: Females donate more frequently than males, a difference that did not change over time. Only a few genderdifferences were seen in donor motives and the donation experience; however, these differences may be relevantto address the gender imbalance in kidney donations.

Abstract [en]

INTRODUCTION: We present a case report of ectopic pregnancy (EP) after simultaneous pancreas-kidney transplantation (SKPTx). PRESENTATION OF CASE: A 33-year-old female status post SKPTx suddenly got abdominal pain in the lower level. She had high human chorionic Gonadotropin test. Ultrasonography revealed that there was no fetus in the uterus but a dilated right fallopian tube, which strongly suggested ectopic pregnancy. An emergency operation was performed and a dilated right side uterine tube was found with adhesions to her transplant. Salpingectomy was performed and no visible injury to the pancreas was found by the procedure. Pathological evaluation showed ectopic pregnant fetus, and no pancreas dysfunction was observed after the operation. DISCUSSION: This is the first case and operation report of EP after SKPTx. We should consider various causes of acute abdomen as well as several pathological condition in the transplanted pancreas such as pancreatitis, abscess, and thrombosis in vessels in the organ. Moreover, transplanted pancreas in abdomen is easily misrecognized as adipose tissue and there is high risk that the organ to get injured surgically. CONCLUSION: EP should be included in the different diagnosis in SKPTx female patients who get acute abdominal pain. It is highly desirable that transplant surgeon is included in the operation team for EP of these patients. (C) 2016 The Authors. Published by Elsevier Ltd on behalf of IJS Publishing Group Ltd.

Abstract [en]

Aim:

Accurate detection of recurrent disease and restaging are essential in the postoperative surveillance of many patients with pheochromocytomas (PHEOs) and paragangliomas (PGLs). In this study, the impact of positron emission tomography (PET) and PET/computed tomography (CT) with 11C-hydroxyephedrine (HED) was evaluated for the postoperative surveillance and diagnosis of recurrent disease and for functional monitoring of locoregional and systemic therapy.

Methods:

One hundred and eleven HED-PET and PET/CT examinations performed in 48 patients after surgical intervention for PHEO/PGL were analyzed retrospectively. In a subgroup of 16 patients who underwent systemic and locoregional therapies, the tracer uptake in tumors was also measured as the functional volume (FV), maximum standardized uptake value (SUVmax), mean SUV (SUVmean) and as the total catecholamine transporter tumor volume (TCTTV) calculated as TCTTV = FV × SUVmean. The PET imaging results were correlated with CT/magnetic resonance imaging findings and biochemical and clinical follow-up data.

Results:

In the first postoperative examination, HED-PET was positive in 24/48 and negative in 24/48 patients with no false-positive results, yielding 92.3% sensitivity and 100% specificity. For the 16 patients, there was a significant correlation between FV and SUVmax and SUVmax and TCTTV. TCTTV correlated significantly with plasma and urinary catecholamines. In 11/16 patients, SUVmax and TCTTV increased/decreased in parallel but not in the remaining 5 patients.

Conclusion:

HED-PET and PET/CT were found to be valuable in the postoperative follow-up in detecting recurrent and metastatic disease. In a subgroup of patients, functional monitoring of systemic and locoregional therapies was feasible by assessing the changes of the TCTTV, and therefore warrants further prospective evaluation.

Abstract [en]

Background. The increase of live kidney donation (LKD) demands that we scrutinize its long-term consequences. Socialized medicine in Sweden has allowed us to survey long-term consequences of LKD with a high response rate. Methods. Between 1974 and 2008, 455 LKDs were performed; 28 donors were deceased and 14 had moved abroad at the time of the survey. Of the remaining 413, 96% agreed to participate in a retrospective study with laboratory testing and answering a questionnaire. Results. Mean age at donation was 49 +/- 10 years, and the mean time since nephrectomy was 11 +/- 7 years (range 1-33). No death was of renal cause. S-creatinine at follow-up was 93 +/- 18 mu mol/L, 28% had treated hypertension, of whom only 52% had BP <140/90. Eleven per cent had spot microalbuminuria, and 1% were diagnosed with diabetes mellitus. Seventy-one per cent had check-ups at least every second year, but 14% had no check-ups. Eighty per cent would be willing to donate again if it were possible, and only 3% regretted the donation. Conclusion. Renal function is well preserved in the long term after donation, no case of end-stage renal disease was identified, and a large majority of our donors would donate again if it were possible. Although rates of microalbuminuria and hypertension were at expected levels, a significant number of donors demonstrated elevated blood pressure levels and inadequate antihypertensive treatment. A relatively large number of donors did not receive regular check-ups. Both of these issues demonstrate the need for a better-structured lifelong follow-up.
