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/m, and donors with more than two renal arteries were independent predictive factors for PT prolongation.

CONCLUSION

Male sex, BMI ≥ 25 kg/m, and two or more renal arteries are predictive factors for prolonged PT for donors in LDN.
