Objective To systematically review the effectiveness and safety of flexible ureteroscope lithtripsy (fURL) and percutaneous nephrolithotomy (PCNL) in treating renal calculus. Methods Such databases as MEDLINE, EMbase, The Cochrane Library, CNKI, CBM, VIP, and WanFang Data from January, 1990 to August, 2012 were searched to comprehensively collect the clinical trials that compared fURL and PCNL in treating renal calculus. Two reviewers independently screened studies according to exclusion and inclusion criteria, extracted data, and assessed the methodological quality. Then, meta-analysis was performed using RevMan 5.1 software. Results Eight non-randomized controlled trials involving 536 patients were included. The results of meta-analysis showed that, PCNL was better than fURL in stone clearance (OR=0.26, 95%CI 0.15 to 0.46), but fURL was better than PCNL in postoperative pyrexia (OR=0.1, 95%CI 0.42 to 3.35), the incidence of blood transfusion (OR=0.17, 95%CI 0.03 to 1.00), and the duration of hospitalization (P=0.45, I2=0%). Conclusion Current evidence has proved that PCNL is better than fURL in decreasing stone clearance, fURL is better than PCNL in complication, the duration of hospitalization, and medical costs.
ObjectiveTo explore the perioperative nursing mode for percutaneous nephrolithotomy (PCNL). MethodsA total of 866 patients with PCNL having undergone lithotripsy between January 2012 and December 2013 in our hospital were included in our study. Before surgery, they received position training, health education and psychological nursing. After surgery, patients received an integral medical wound care and pipeline management, as well as management of infectious shock and intercostal neuralgia. At the same time, we gave them dietary guidance and other health guidance. ResultsAll the patients were successfully discharged from hospital. Postoperative infection rate was 2.4%, septic shock rate was 0.2%, bleeding rate was 2.2%, urinary leakage rate was 1.5%, the rate of pneumothorax was 0.6%, subcutaneous emphysema rate was 0.3%, and intercostal neuralgia rate was 0.6%. The average hospital stay was (11.2±2.8) days. ConclusionThe innovative nursing mode and techniques have great significance on the success of PCNL surgery.
ObjectiveTo analyze the causes and characteristics of massive hemorrhage secondary to percutaneous nephrolithotomy (PCNL) and assess the value of superselective renal artery embolization in the management of this condition. MethodsThe imaging data and prognosis of 28 patients who developed repeated massive hemorrhage secondary to PCNL and underwent superselective renal artery embolization between April 2005 and June 2013 were reviewed. ResultsFollowing superselective renal artery embolization, hemorrhage was effectively controlled in all the 28 patients. Follow-up lasted from 6 to 62 months, averaging 41.6 months. No hematuria or other complications occurred during the follow-up period. ConclusionSuperselective renal artery embolization is safe and effective in managing massive hemorrhage secondary to PCNL, and it may be used as a preferred treatment for patients who are refractory to expectant treatments.
ObjectiveTo assess the efficacy and safety of percutaneous nephrolithotomy (PCNL) versus ureteroscopic lithotripsy (URL) in the treatment of impacted proximal ureteral stones>1 cm. MethodsWe electronically searched PubMed, Cochrane library, Embase, WanFang, Chinese National Knowledge Infrastructure and VIP database (by the end of July 2015) to collect randomized controlled trials involving PCNL vs. URL for the treatment of impacted proximal ureteral stones> 1 cm. The quality of those trials were assessed. Data were extracted and analyzed with RevMan 5.3 software. ResultsSix randomized controlled trials were finally obtained after screening. A total of 487 patients were included for a Meta-analysis. The results showed that, as compared with the control group (URL), the patients in the trial group (PCNL) had the following features: ① There was a remarkable improvement of stone clearance rate [RR=1.20, 95% CI (1.09, 1.33), P=0.000 3].② There was no statistical difference in postoperative fever rates, urinary tract perforation rates [RR=1.73, 95%CI (0.43, 7.00), P=0.45; RR=1.02, 95%CI (0.11, 9.37), P=0.99], but the incidence of hematuria was higher [RR=1.99, 95%CI (1.09, 3.62), P=0.03], and the mean operative duration was longer [WMD=30.03 minutes, 95%CI (10.04, 50.02) minuntes, P=0.003].③ The mean hospitalization stay was delayed by an average of 3.73 days [WMD=3.73 days, 95%CI (3.02, 4.44) days, P<0.000 01]. ConclusionPCNL is better than URL in the stone clearance rate, while patients in the PCNL group have to stay in the hospital much longer, and should bear longer mean operative duration.
Objective To compare clinical outcomes of percutaneous nephrolithotomy (PCNL) in patients who initially presented with and without urosepsis. Methods The study included patients who underwent PCNL for renal and ureter urolithiasis removal from January 2010 to December 2014 in our hospital. A 1∶1 matched-pair analysis was performed to compare outcomes and complications of patients who had obstructive urolithiasis with urosepsis initially (OUU) with patients who had obstructive urolithiasis with no urosepsis initially (NOUU) before PCNL. Results A total of 172 patients were included involving 122 (71%) males and 50 (29%) females with a mean age of 46.2 years (range 32 to 65 years). There were no significant differences between two groups in age, gender, BMI, complications, the size of the stones, stone's number and stone location (P>0.05). OUU groups had the similar stone-free rates (86.0%vs. 84.8%, P=0.829) as the NOUU group. OUU group had higher overall complications rate, longer duration of nephrostomy tube (NT), longer hospital length of stay (LOS), longer courses of postoperative antibiotics and higher grade of antibiotics after PCNL (all P<0.05). Higher fever developed postoperatively (11.6%vs. 3.5%, P=0.043), higher asymptomatic bacteriuria (11.6% vs. 3.5%, P=0.043) and symptomatic urinary tract infections (10.5% vs. 2.3%, P=0.029) were also found in OUU groups. There was no significant difference between two groups in sepsis (2.3% vs. 1.2%, P=0.560). Conclusion PCNL after decompression for urolithiasis-related urosepsis has similar success but higher complication rates than obstructive urolithiasis with no urosepsis initially.
ObjectivesTo systematically review the efficacy and safety of laparoscopic pyelolithotomy (LP) versus percutaneous nephrolithotomy (PNL) in treating large (>2 cm) renal pelvic calculi.MethodsDatabases including PubMed, EMbase, Web of Science, The Cochrane Library, CBM, CNKI and WanFang Data were searched for relevant randomized controlled trials (RCTs) comparing LP with PNL for the treatment of large renal pelvic calculi from inception to September 23th, 2017. Two reviewers independently screened literature, extracted data and assessed the risk of bias of eligible studies. Meta-analysis was then performed by using RevMan 5.2 software.ResultsFive RCTs with 447 patients were included. The results of meta-analysis showed that: compared with PNL group, LP group provided a significantly higher stone-free rate (RR=1.07, 95%CI 1.01 to 1.13, P=0.01), lower auxiliary procedure rate (RR=0.36, 95%CI 0.13 to 1.01, P=0.05), less hemoglobin decrease (MD=–0.83, 95%CI –1.05 to –0.61, P<0.000 01) and lower postoperative fever rate (RR=0.36, 95%CI 0.18 to 0.72,P=0.004). However, no significant differences were detected in conversion rate (RR=0.76, 95%CI 0.19 to 3.07, P=0.70), blood transfusion rate (RR=0.40, 95%CI 0.14, to 1.12, P=0.08), postoperative leakage rate (RR=1.87, 95%CI 0.67 to 5.21, P=0.23), operative time (MD=10.49, 95%CI –17.14 to 38.13, P=0.46) and hospital stay (MD=0.53, 95%CI –0.22 to 1.28, P=0.17).ConclusionsLP is superior to PNL with regard to stone-free rate, auxiliary procedure rate, hemoglobin decrease and postoperative fever rate. Due to limited quality and quantity of included studies, more high quality studies are required to verify above conclusions.
ObjectiveTo explore the impact of different tracts on the effectiveness and safety of percutaneous nephrolithotomy (PCNL) on complete staghorn calculus.MethodsPatients with complete staghorn calculus who underwent single channel PCNL by the same surgeon in West China Hospital of Sichuan University from October 2009 to August 2019 were included. The removing time, the rate of immediate stone removal, the average extubating time, and the incidences of postoperate complications such as fever and bleeding were analyzed statistically.ResultsA total of 379 patients were included. There were 146 cases in the upper tract group, 170 cases in the lower tract group and 63 cases in the middle tract group. Compared with the upper and middle tract groups, the lower tract group had shorter stone removing time [(50.34±18.52) vs. (53.41±22.75) vs. (41.79±17.45) min, P<0.001], shorter average extubating time [(5.53±1.83) vs. (6.17±1.44) vs. (4.96±1.91) d, P=0.007]. The rate of immediate stone removal was higher in the the upper tract group (40.56% vs. 32.79% vs. 34.71% ), but there was no statistical difference among the three groups (P=0.447). There was no significant difference among the three groups in the fever incidence (25.44% vs. 24.24% vs. 26.85%, P=0.938) or bleeding incidence (3.54% vs. 3.03% vs. 4.03%, P=1.000). In addition, there were 8 cases of pleural injury in the upper tract group.ConclusionsCompared with the lower and middle tract, PCNL with upper tract has a higher rate of removing stones for complete staghorn calculus, but there was no significant difference among the three groups. The incidences of bleeding and fever after surgery are similar in the three groups, but the risk of pleural injury may be increased in the upper tract group.
