Minimally Invasive Percutaneous Nephrolithotomy

Abstract Background A systematic review and meta-analysis was conducted to compare the safety and efficacy of vacuum-assisted sheaths and conventional sheaths in minimally invasive percutaneous nephrolithotomy (MPCNL) in the treatment of nephrolithiasis. Methods PubMed, Web of Science, Embase, EBSCO, and Cochrane Library databases (updated March 2021) were used to search for studies assessing the effect of vacuum-assisted sheaths in patients who underwent MPCNL. The search strategy and study selection processes were implemented in accordance with the PRISMA statement. Result Three randomized controlled trials and two case-controlled trials that satisfied the inclusion criteria were enrolled in this meta-analysis. Overall, the stone-free rate (SFR) in patients who underwent vacuum-assisted sheaths was significantly higher than that in patients who underwent conventional sheaths (RR 1.23, 95% CI 1.04, 1.46, P = 0.02), with significant heterogeneity among the studies (I2 = 72%, P = 0.03). In terms of the outcome of complications, vacuum-assisted sheath could bring a benefit to the postoperative infection rate (RR 0.48, 95% CI 0.33, 0.70, P < 0.00001) with insignificant heterogeneity among the studies (I2 = 0%, P = 0.68). There was no significant difference in the blood transfusion rate (RR 0.35, 95% CI 0.07, 1.73, P = 0.17), with significant heterogeneity (I2 = 66%, P = 0.35). Three studies contained operative time data, and the results indicated that the vacuum-assisted sheath led to a shorter operative time (MD = − 15.74; 95% CI − 1944, − 12.04, P < 0.00001) with insignificant heterogeneity (I2 = 0%, P = 0.91). Conclusion The application of a vacuum-assisted sheath in MPCNL improves the safety and efficiency compared to the conventional sheath. A vacuum-assisted sheath significantly increases the SFR while reducing operative time and postoperative infection.

Abstract Background A systematic review and meta-analysis was conducted to compare the safety and efficacy between the vacuum-assisted sheath and conventional sheath in minimally invasive percutaneous nephrolithotomy (MPCNL) in the treatment of nephrolithiasis. Methods PubMed, Web of Science, Embase, EBSCO, and Cochrane library databases (updated March 2021) were searched for studies assessing the effect of vacuum-assisted sheath in patients who underwent MPCNL. The search strategy and study selection processes were managed according to the PRISMA statement. Results Three randomized controlled trials and two case-controlled trials that satisfied the inclusion criteria were enrolled in this meta-analysis. Overall, the stone-free rate (SFR) in patients who underwent vacuum-assisted sheath was significantly higher than those who underwent conventional sheath (RR = 1.18, 95% CI = 1.08,1.29; P = 0.0002), with insignificant heterogeneity among the studies (I2 = 44%, P = 0.13). In terms of the outcome of complications, vacuum-assisted sheath could bring a benefit to the postoperative infection rate (RR = 0.45, 95%CI = 0.33,0.61; P < 0.00001) with insignificant heterogeneity among the studies (I2 = 0%, P = 0.76). There was no significant difference in blood transfusion rate (RR = 0.54, 95%CI = 0.23,1.29; P = 0.17) with insignificant heterogeneity (I2 = 41%, P = 0.15,). Only two studies reported the perforation and the results were statistically insignificant (RR = 0.25, 95%CI = 0.05,1.17; P = 0.08) with insignificant heterogeneity (I2 = 0%, P = 0.43). Conclusions Using vacuum-assisted sheath in MPCNL improves the safety and efficiency compared to the conventional sheath. Vacuum-assisted sheath significantly increases the SFR and reduces complications like postoperative infection, blood transfusion, and perforation

Abstract Background The goal for using smaller caliber instruments in PNL was to reduce the access-related complications and to decrease morbidity. The objective of this study was to evaluate the safety and efficacy of Chinese minimally invasive percutaneous nephrolithotomy (MIPNL) in the treatment of renal stones ≤ 20 mm. Results Sixty-seven patients completed the study protocol. The mean age was 41.10 ± 13.99 years (range 18–68 years). There were 43 (64%) male and 24 (36%) females. The mean stone size was ranged from 78.5 to 439.6 mm2 (mean ± SD 172.48 ± 69.54 mm2). The overall SFR was (82%). Twelve (18%) needed post-MIPNL auxiliary procedure, in the form of second MIPNL in 3 (4.5%) cases, SWL in 7 (10%), and RIRS in 2 (3%) cases. The intraoperative complication was present in four patients (5%) include bleeding necessitate blood transfusion in one patient (1.5%) and renal collecting system perforation 3 (4.5%). The postoperative complication was urine leakage 5 (7.5) and fever in 6 (9%) of patients. Conclusion Chinese MIPNL is safe and effective method for treatment of renal stone ≤ 20 mm size with satisfactory SFR and low complication rate when SWL failed or contraindicated. It is considered a feasible treatment alternative to standard PNL, in the absence of flexible URS or miniature nephroscope.
