Abstract
Objective ro explore the impact of pelvis pressure on renal morphology in minimal damage percutaneous nephrolithotomy (MPCNL) . Methods Fifty patients with renal calculi were cured by MPCNL. The intrapelvic renal pressure was monitored with urodvnamic instrument, which was connected with ureteral catheter, and the data of kidney and perinephric morphological changes were analyzed by CT performed immediately and on the 1st, 3rd and 5th day after the surgery. Those with intrapelvic pressure ≥40 cmH2O for 5 minutes were assigned to the high pressure group (n=21) , and the remainders constituted the low pressure group (n=29). Results The average intrapelvic renal pressure was 26.5(l3～149) cmH2O in high pressure group, and 22.4 ( 11～l25) cmH2O in low pressure group. The perirenal effusion was found in all patients immediately after surgery, and the renal parenchyrna was thickened by about 1.2～4.3mm, which was significantly different from that before surgery ( P＜O.05). After surgery, the immediate thickness of the renal parenchyrna was increased in high pressure group (17.4±1.7mm) compared with low pressure group (16.21±2.3mm, P＜0.05), hereafter the effusion was absorbed gradually, and the thickness of the renal parenchyrna recovered to the level of that of before surgery. Conclusions The intrapelvic renal pressure of ≥40cmH2O is only maintained for a few minutes during MFCNL, and the phenomenon of regurgitation and extravasation of the perfusate is common. The higher the pressure, the severer the phenomenon though the diffusate may be absorbed soon.关键词
