Abstract:

Objective

To compare the safety and efficacy of negative pressure suction sheath and peel-away sheath in minimally invasive percutaneous nephrolithotomy (MPCNL) for 2-5 cm renal calculi.

Methods

From 2019, 50 patients with 2-5 cm renal calculi were enrolled into two groups. 18 F percutaneous tract was established, suction sheath and peel-away sheath were used in different groups. Preoperative data, operation time, lithotripsy time, stone removal volume and perioperative complications were recorded and analyzed statistically.

Results

There was no significant difference in preoperative data between the two groups. There was no significant difference in stone removal volume [(8±3) vs (8±4) mm3, P=0.781] during MPCNL, but the time consumed [(37±16) vs (50±20) min, P=0.016] for lithotripsy in the negative pressure suction sheath group was significantly shorter than peel-away sheath group, therefore, the lithotripsy efficiency [(13.5±1.0) vs (9.7±1.14) mm3/h, P<0.001] of the negative pressure suction sheath group was significantly higher than peel-away sheath group. The total operation time [(54±16) vs (67±20) min, P=0.014] in the negative pressure suction sheath group was significantly shorter than that of ordinary sheath group. The decrease of hemoglobin [(14±6) vs (19±8) g/L, P=0.013] in the negative pressure suction sheath group was less than peel-away sheath group. The postoperative fever rate (4% vs 24%, P=0.042) was lower in the negative pressure suction sheath group.

Conclusions

Negative pressure suction sheath in MPCNL can improve the lithotripsy efficiency, shorten the operation time, effectively reduce the blood loss and postoperative fever, which is a safe and effective technique.
