The Effect Of Renal Artery Occlusion Time On Urinary Renal Recovery In The Normal Atmospheric Temperature

Objective:To investigate the relationship between renal artery occlusion time and renal ischemia recovery of urinary function in normal atmospheric temperature, to provide the basis for further nephron-sparing surgery(NSS).Methods:A retrospective analysis of83cases of renal artery occlusion surgery in normal atmospheric temperature,18cases of functional solitary kidney,47cases of laparoscopic surgery,36cases of Tla solitary kidney,4cases of hamartoma,7cases of calyx stones;15cases of Diabetes mellitus (DM)/hypertension (EH);36cases of open surgery group,23cases of single Tla tumors,2cases of multiple tumors,11cases of renal calyx stones,14cases of DM/EH, of which40cases of renal artery block time less than20min,43cases of which more than20min. Comparison was carried between Urinary Renal Recovery and Renal Artery Occlusion Time. All data was analysed through the professional statistical software SPSS17.0, with P0.05for the difference is statistically significant.Results:(1) All operations were successful;(2) without diabetes and hypertension groups:warm ischemia time in13.25±5.83min, kidney urinary function recovery time15.05±7.53min; warm ischemia time in 29.25±7.34min, urinary kidney function recovery time27.42±6.33min; difference between renal artery clamping time and renal function recovery urinary has statistical significance. The warm ischemia time control urinary function in the kidneys within20minutes recovery is greater than urinary function recovery more than20minutes.(3) diabetes or (and) hypertension groups, warm ischemia time in13.37±5.98min, kidney urinary function recovery time22.37±6.76min; warm ischemia time in29.89±5.04min, urinary kidney function recovery time39.42±9.06min; the difference is statistically significant between diabetes or (and) hypertension group with renal artery occlusion time and diabetes or (and) hypertension group, diabetes or (and) renal hypertension urinary function recovery time is greater than the group without diabetes and hypertension.(4) open surgery group and laparoscopic surgery without diabetes and hypertension:warm ischemia time in20minutes, laparoscopic renal urinary function recovery time at15.68±6.34min; open surgery recovery time of renal function in urinary14.72±7.88min; less than20minutes of warm ischemia time laparoscopic and open group were no difference in recovery of renal urinary function; warm ischemia time more than20minutes, laparoscopic urological renal function recovery time in28.57±6.74min; open surgery recovery time of renal function in urinary26.68±8.02min; more than20minutes of warm ischemia time, laparoscopic and open renal urinary function has no difference in recovery. Diabetes or (and) open and laparoscopic surgery hypertension group:warm ischemia time in20minutes, laparoscopic urological renal function recovery time in22.74±6.83min; open surgery urinary renal function recovery time in20.03±7.42min; less than20minutes of warm ischemia time, laparoscopic and open groups was no difference in recovery of renal urinary function; warm ischemia time greater than20minutes, laparoscopic urological renal function recovery time in40.34±6.23min; open renal surgery urinary function recovery time at38.76±8.59min; more than20minutes of warm ischemia time, laparoscopic and open group has no difference in recovery of renal urinary function. Laparoscopic and open surgery for kidney urinary function recovery was not statistically significant.(5) the occurrence of renal insufficient:warm ischemia time in20minutes (five cases of functional solitary kidney)1year after uncomplicated renal insufficiency (serum creatinine); warm ischemia time more than20minutes (13cases feature isolated occurrence of renal kidney)1year after insufficiency (serum creatinine) for three cases, warm ischemia time of less than20minutes of long-term renal insufficiency were significantly less than warm ischemia time more than20minutes of the occurrence of renal insufficiency rate, there is a significant difference.(6) renal function insufficiency is happening:hot ischemia, is less than20min (5cases of functional isolated kidney) one year without complicated with renal insufficiency (Cr); Warm ischemia time is more than20min (13cases of functional isolated kidney)1 years later, the renal function is not complete (Cr) in3cases, warm ischemia time is less than20min long-term renal function insufficiency rates significantly lower than the thermal ischemia time is more than20min the incidence of renal function is not complete, with statistical difference (P <0.05). Note:Renal artery occlusion, recovery of renal function and renal function in urinary refer to kidney surgeryConclusions:In the surgery of blocking the renal artery, renal warm ischemia time control in less than20minutes has obvious advantages to restore kidney function and lower urinary forward the insufficient incidence of renal.
