Clinical predictors associated with prolonged pneumoperitoneum time in laparoscopic living donor nephrectomy.
Background: Kidney transplantation (KT) is a useful treatment option for patients with end-stage chronic kidney disease to avoid dialysis and achieve a good quality of life. In Japan, approximately 90% of kidneys for KT are obtained from living kidney donors. Laparoscopic renal nephrectomy (LDN) is the most commonly performed KT procedure in Japan. We aimed to determine the clinical variables that influence the prolongation of pneumoperitoneum time (PT) in LDN.
Method: This retrospective study was carried out on 218 consecutive patients who underwent LDN at Gifu University Hospital. T The enrolled patients were divided into two groups according to the third quartile of PT in the LDN, with those in the lower third quartile (Q3) as Group 1 and those in the upper Q3 as Group 2. The primary endpoint was identification of predictive factors for prolonged PT.
Result: In total, 178 patients were included in the analysis. For all patients, the median PT, estimated blood loss, and warm ischemic time were 170 min, 20 mL, and 4 min, respectively. Significantly longer PT was observed in Group 2 than in Group 1. Multiple regression analysis results showed that male donors, body mass index ≥ 25 kg/m2, and donors with more than two renal arteries were independent predictive factors for PT prolongation.
Conclusion: Male sex, BMI ≥ 25 kg/m2, and two or more renal arteries are predictive factors for prolonged PT for donors in LDN.
期刊介绍：
Clinical and Experimental Nephrology is a peer-reviewed monthly journal, officially published by the Japanese Society of Nephrology (JSN) to provide an international forum for the discussion of research and issues relating to the study of nephrology. Out of respect for the founders of the JSN, the title of this journal uses the term “nephrology,” a word created and brought into use with the establishment of the JSN (Japanese Journal of Nephrology, Vol. 2, No. 1, 1960). The journal publishes articles on all aspects of nephrology, including basic, experimental, and clinical research, so as to share the latest research findings and ideas not only with members of the JSN, but with all researchers who wish to contribute to a better understanding of recent advances in nephrology. The journal is unique in that it introduces to an international readership original reports from Japan and also the clinical standards discussed and agreed by JSN.
