OBJECTIVETo compare the graft survival, donor and recipient outcome, donor satisfaction, and complications of laparoscopic (LDN) and open donor nephrectomy (ODN) in kidney transplantation.
PATIENTS AND METHODSIn a randomized controlled trial, 100 cases each of LDN and ODN were compared. We modified the standard LDN procedure to make it less expensive.
RESULTSThe mean ( SD ) operative duration was 152.2 (33.9) min for ODN and 270.8 (58.5) min for LDN, and the mean duration of kidney warm ischaemia was 1.87 min for ODN and 8.7 min for LDN. Only one LDN required conversion to ODN because of bleeding. The mean follow-up in the LDN and ODN groups was not significantly different (406.1 vs 403.8 days). The mean ( SD ) score for donor satisfaction was 17.3 (3.5) for ODN and 19.6 (1.0) for LDN. The rate of ureteric complications was 2% for ODN and none for LDN. As determined by serum creatinine levels at 3, 21-30, 90, 180 and 365 days after surgery, graft function was not significantly different between ODN and LDN. Long-term graft survival was 93.8% for LDN and 92.7% for ODN.
CONCLUSIONSCompared to ODN, LDN was associated with greater donor satisfaction, less morbidity and equivalent graft outcome.
The 986S, 990G and 1011Q alleles were associated with a recurrent calcium kidney stone-forming state. 986S and 1011Q alleles, but not 986S, were associated with hypercalcaemia.
The aim of this study is to investigate the serum levels of parathyroid hormone (PTH), calcitonin, 1,25 (OH)(2) vitamin D3, estradiol and testosterone in male patients with active renal calcium stone disease compared with controls and investigate their relationship with serum/urinary biochemistry. Male active renal calcium stone formers (ASF) were enrolled from December 2008 to April 2009. Controls were selected from age and sex matched individuals. Two 24-h urine samples and a blood sample were withdrawn from each participant while they were on free diet. Serum 1,25 (OH)(2) vitamin D3 levels in the ASF and control groups were 127 ± 40 and 93 ± 35 pmol/l (p < 0.001). Serum levels of PTH, calcitonin, estradiol and testosterone were not statistically different between the ASF and control groups (all p > 0.05). Serum 1,25 (OH)(2) vitamin D3 was associated with higher urinary excretion of calcium and phosphorus in ASF patients. Serum levels of calcitonin were related to less urinary excretion of calcium in the control group. Serum testosterone was related to higher urinary excretion of uric acid in ASF patients and to higher urinary excretion of oxalate in the control group. 1,25 (OH)(2) Vitamin D3 is an important hormone in the pathogenesis of recurrent renal calcium stone disease and could increase renal stone risk by increasing the urinary excretion of calcium and phosphorus. There is a possibility of testosterone involvement in the pathogenesis of renal stones through higher urinary uric acid and oxalate excretion.
Even in our first report with limited experience, it seems that the efficacy of PCNL with ultrasonography in supine position is comparable to PCNL in prone position with fluoroscopy with no more complications.
Introduction: In this study the full sequence of the calcitonin receptor gene (CALCR) in a group of Iranian males suffering from recurrent calcium urinary stones was compared with that of a control group. Methods: Serum and urinary biochemistry related to urolithiasis were evaluated in 105 males diagnosed with recurrent kidney calcium stones and 101 age-matched healthy control males. The polymerase chain reaction single-strand conformation polymorphism method was used to detect new polymorphisms in the CALCR. Results: Nine polymorphisms were detected; seven were in the non-coding and two in the coding region. The T allele associated with the 3′UTR+18C>T polymorphism was observed exclusively in the stone formers. The exact odds ratio for the T allele in this locus for those at risk of stone formation was 36.72 (95% CI 4.95-272.0) (p < 0.001). The mean (standard deviation) urine calcium concentration was 117 (60) mg/l in patients with the C allele and 152 (72) mg/l in those with the T allele (p = 0.03). In addition, IVS1-6T>C and IVS1insA polymorphisms in intron 1 were associated with kidney stone disease (p < 0.001). Regarding single nucleotide polymorphism 447, mean (standard deviation) of serum calcitonin levels were 16.7 (18.7) pg/ml, 10.5 (11.0) pg/ml and 9.94 (9.7) pg/ml in subjects with TT, TC and CC genotypes, respectively (p = 0.01). Conclusion: Our data indicate a potential association between 3′UTR+18C>T and intron 1 polymorphisms in the CALCR and the risk of kidney stone disease.
