Multi-aspect analysis of ureteral access sheath usage in retrograde intrarenal surgery: A RIRSearch group study

Objective:To evaluate the effect of ureteral access sheath(UAS)use and calibration change on stone-free rate and complications of retrograde intrarenal surgery(RIRS).Methods:Data from 568 patients undergoing RIRS for kidney or upper ureteral stones were retrospectively included.Firstly,patients were compared after 1:1 propensity score matching,according to UAS usage during RIRS(UAS used[+]87 and UAS non-used[−]87 patients).Then all UAS+patients(n=481)were subdivided according to UAS calibration:9.5-11.5 Fr,10-12 Fr,11-13 Fr,and 13-15 Fr.Primary outcomes of the study were the success and complications of RIRS.Results:Stone-free rate of UAS+patients(86.2%)was significantly higher than UAS−patients(70.1%)after propensity score matching(p=0.01).Stone-free rate increased with higher caliber UAS(9.5-11.5 Fr:66.7%;10-12 Fr:87.0%;11-13 Fr:90.6%;13-15 Fr:100%;p<0.001).Postoperative complications of UAS+patients(11.5%)were significantly lower than UAS−patients(27.6%)(p=0.01).Complications(8.7%)with 9.5-11.5 Fr UAS was lower than thicker UAS(17.2%)but was not statistically significant(p=0.09).UAS usage was an independent factor predicting stone-free status or peri-and post-operative complications(odds ratio[OR]3.654,95%confidence interval[CI]1.314-10.162;OR 4.443,95%CI 1.350-14.552;OR 4.107,95%CI 1.366-12.344,respectively).Conclusion:Use of UAS in RIRS may increase stone-free rates,which also increase with higher caliber UAS.UAS usage may reduce complications;however,complications seemingly increase with higher UAS calibration.

Retrograde intrarenal surgery for lower pole stones utilizing stone displacement technique yields excellent results

Objective:To evaluate the long-term stone-free rate(SFR)of retrograde intrarenal surgery(RIRS)in the treatment of lower pole renal calculi using only basket relocation and identify independent predictors of stone-free status.Methods:All consecutive patients undergoing RIRS lower pole renal calculi at a single highvolume tertiary center were analyzed retrospectively.Lower pole stones were relocated to the upper pole,where laser lithotripsy was performed.All patients were followed up in the clinic following the surgery and yearly thereafter.The stone-free status was assessed with a combination of an abdominal ultrasound and abdominal X-ray,or an abdominal non-contrast computed tomography if the stones were known to be radiolucent.Results:A total of 480 consecutive patients who underwent RIRS for treatment of lower pole renal calculi,between January 2012 and December 2018,were analyzed from a prospectively maintained database of 3000 ureteroscopies.With a median follow-up time of 18.6 months,the mean SFR was 94.8%.The procedures were unsuccessful in 26(5.4%)patients due to unreachable stones.The median stone size of the unreachable stones was 12 mm(range 10e30 mm).Multivariable logistic regression analysis revealed two predictors of SFR for lower pole stones:a small cumulative stone burden(odds ratio[OR]:0.903,95%confidence interval[CI]:0.867e0.941,p<0.0001)and preoperative ureteral stent insertion(OR:0.515,95%CI:0.318e0.835,pZ0.007).Conclusion:The long-term SFR of RIRS for the treatment of lower pole stones with basket displacement with appropriate patient selection is high.

Retrograde intrarenal surgery vs miniaturized percutaneous nephrolithotomy to treat lower pole renal stones 1.5-2.5 cm in diameter

AIM To compare the outcomes of retrograde intrarenal surgery(RIRS) and miniaturized percutaneous nephrolithotomy(mini-PCNL) in treating lower pole(LP) renal stones with a diameter of 1.5-2.5 cm.METHODS A total of 216 patients who underwent mini-PCNL(n = 103) or RIRS n = 113) for LP stones with a diameter of 1.5-2.5 cm were enrolled between December 2015 and April 2017 at the Urology Department of Ningbo Urology and Nephrology Hospital.RESULTS Significant differences were found in the hospital stay(9.39 ± 4.01 vs 14.08 ± 5.26, P < 0.0001) and hospitalization costs(2624.5 ± 513.36 vs 3255.2 ± 976.5, P < 0.0001) between the RIRS and mini-PCNL groups. The mean operation time was not significantly different between the RIRS group(56.48 ± 24.77) and the mini-PCNL group(60.04 ± 30.38, P = 0.345). The stone-free rates at the first postoperative day(RIRS vs mini-PCNL: 90.2% vs 93.2%, P = 0.822) and the second month postoperatively(RIRS vs mini-PCNL: 93.8% vs 95.1%, P = 0.986) were not significantly different.CONCLUSION RIRS and mini-PCNL are both safe and effective methods for treating LP stones with a diameter of 1.5-2.5 cm. RIRS can be considered as an alternative to PCNL for the treatment for LP stones of 1.5-2.5 cm.

Retrograde intrarenal surgery:An expanding role in treatment of urolithiasis

During the past 3 decades,the surgical management of kidney stones has undergone many technological advances and one is the development of the flexible ureteroscopy.The development of this instrument as well as ancillary equipment such as baskets,graspers,and others,and improvements in lithotripsy with Holmium:YAG laser have led to expand its indications with diagnostic and therapeutic management of medical issues of the upper urinary tract such as urolithiasis and urothelial tumors.The objective of this review is to describe its indications and results in the different scenarios for the treatment of urinary stones.

Use of a new retrograde filling material(Biodentine) for endodontic surgery: two case reports

Mineral trioxide aggregate（MTA） is considered at the present time as the gold standard for root-end filling in endodontic surgery.However, this biocompatible material presents several drawbacks such as a long setting time and handling difficulties. The aim of this article is to present a new commercialized calcium silicate-based material named Biodentine with physical improved properties compared to MTA in a clinical application. Two endodontic microsurgeries were performed by using specific armamentarium（microsurgical instrumentation, ultrasonic tips） under high-power magnification with an operatory microscope. Biodentine was used as a root-end filling in order to seal the root canal system. The two cases were considered completely healed at 1 year and were followed for one more year. The 2-year follow-up consolidated the previous observation with absence of clinical symptoms and radiographic evidence of regeneration of the periapical tissues.

Retrograde intrarenal surgery in pediatric patients

Urinary tract stone disease is seen at a level of 1%-2% in childhood(< 18 years).In recent years,however,there has been a marked increased in pediatric stone disease,particularly in adolescence.A carbohydrateand salt-heavy diet and a more sedentary lifestyle are implicated in this increase.Although stone disease is rare in childhood,its presence is frequently associated with metabolic or anatomical disorders or infectious conditions,for which reason there is a high possibility of post-therapeutic recurrence.Factors such as a high possibility of recurrence and increasing incidence further enhance the importance of minimally invasive therapeutic options in children,with their expectations of a long life.In children in whom active stone removal is decided on,the way to achieve the highest level of success with the least morbidity is to select the most appropriate treatment modality.Thanks to today's advanced technology,renal stones that were once treated only by surgery can now be treated with minimally in-vasive techniques,from invasion of the urinary system in an antegrade(percutaneous nephrolithotomy) or retrograde(retrograde intrarenal surgery) manner or shock wave lithotripsy to laparoscopic stone surgery.This compilation study examined studies involving the RIRS procedure,the latest minimally invasive technique,in children and compared the results of those studies with those from other techniques.

Sheathless and fluoroscopy-free retrograde intrarenal surgery:An attractive way of renal stone management in high-volume stone centers

Objective:To evaluate the efficacy and safety of sheathless and fluoroscopy-free flexible ureterorenoscopic laser lithotripsy(FURSL)for treating renal stones.Methods:Between May 2015 and May 2017,135 patients with renal stones treated with sheathless and fluoroscopy-free FURSL were prospectively evaluated.Our technique involved a semirigid ureteroscopic assessment of the ureter,and the guidewire was left in situ to railroad the flexible ureteroscope.A holmium laser was used to fragment and dust the stones;fragments were neither grasped nor collected.Results:The study population consisted of 135 patients including 85 males(62.96%)and 50 females(37.04%)with a mean age of 40.65 years(range:3-70 years)were evaluated.The mean stone size was 17.23 mm(range:8-41 mm).Complete stone-free status was achieved in 122(90.37%)patients and clinically insignificant residual fragments(CIRF)in two(1.48%),while residual stones were still present in 11(8.15%)patients.Postoperative complications occurred in 23(17.4%)cases and were mostly minor,including fever in 17(12.6%),pyelonephritis in four(3.0%),subcapsular hematoma in one(0.7%)and steinstrasse in one(0.7%).These complications were Clavien Ⅰ-Ⅱ,GⅠ in 17(12.6%)patients,GⅡ in five(3.7%),and Clavien Ⅲb in one(0.7%).No major complications were observed.Stone size2 cm,operative time ≥30 min,and lasing time ≥20 min were significantly associated with a higher rate of complications and lower stone-free rates upon univariate analysis(p<0.05).Conclusion:Sheathless and fluoroscopy-free FURSL are effective and safe for renal stone management,especially for stones under 2 cm in diameter.This process is a feasible option for avoiding sheath complications,which can protect surgeons from the negative effects of radiation.

Massive retroperitoneal hematoma as an acute complication of retrograde intrarenal surgery:A case report

BACKGROUND Retrograde intrarenal surgery(RIRS)has been proven to be a safe and effective treatment modality in large-scale quantitative studies.However,although its safety profile has been established,it also has a potential risk of life-threatening complications.We here describe our experience with a patient who developed a huge periureteral hematoma after RIRS with holmium laser lithotripsy.CASE SUMMARY A 73-year-old woman visited our center with a complaint of gross hematuria.An enhanced computed tomography(CT)scan revealed a 1.5-cm left renal pelvis stone with hydronephrosis.The patient underwent RIRS.During the surgery,a 12/14-Fr ureteral access sheath was applied and a 6-Fr ureteral catheter was indwelled thereafter.On postoperative day 1,she experienced aggravated left flank pain and left lower-quadrant tenderness without rebound tenderness.A follow-up CT scan was taken,which revealed a huge hematoma in the periureteral space,not in the perirenal space,with suspicious contrast medium extravasation.Immediate angiography was performed;however,it showed no evidence of active bleeding.She was conservatively managed with hydration and antibiotic and nonsteroidal anti-inflammatory drug therapy,and was discharged on postoperative day 7.However,she visited our outpatient department with recurrent left flank pain at 5 d from discharge.Ultrasonography confirmed that the double J-stent was intact.To rule out stent malfunction,the stent was changed.Decreased size of the hematoma was observed in the imaging studies,and conservative management for candiduria was performed for 1 wk.CONCLUSION Although RIRS is an effective and safe procedure for the management of renal stones,clinicians should be aware of its potential complications.

Comparison of the trauma between combined retrograde intrarenal surgery and mini-percutaneous nephrolithotomy for upper ureteral calculi

Objective: To compare the trauma between combined retrograde intrarenal surgery and mini-percutaneous nephrolithotomy for upper ureteral calculi. Methods: Patients with upper ureteral calculi who received lithotripsy in Pengzhou Hospital of Traditional Chinese Medicine between February 2015 and March 2017 were selected and randomly divided into two groups;RIRS group received combined retrograde intrarenal surgery and the Mini-PCNL group received mini-percutaneous nephrolithotomy. 3 d after surgery;the contents of liver and kidney function indexes and stress hormones in serum as well as the expression of CD4+T cell transcription factors in peripheral blood were measured. Results: Serum ALT;AST;γ-GT;BUN and Cr contents of RIRS group 3 d after surgery were not significantly different from those of Mini-PCNL group;and HO-1;ET-1;ACTH;Cor and YKL-40 contents in serum as well as RORγt and T-bet mRNA expression in peripheral blood were significantly lower than those of Mini-PCNL group while Gata-3 and Foxp3 mRNA expression in peripheral blood were higher than those of Mini-PCNL group. Conclusion: Combined retrograde intrarenal surgery for upper ureteral calculi activates less stress response and inflammatory response than mini-percutaneous nephrolithotomy.

Clinical application of retrograde cerebral perfusion for brain protection during the surgery of ascending aortic aneurysm:50 cases report

Objective To assess retrospectively the effects of different protective methods on brain in ascending aortic aneurysm surgery. Methods In 65 patients, aneurysm was dissected to the aortic arch or right arch. To protect brain, deep hypotermic circulatory arrest ( DHCA.) combined with retrograde cerebral perfusion ( RCP) June 2003 Vol11 No2 through the superior vena cava ( n = 50) and simple DHCA ( n = 15) were used during the procedure. Blood samples for lactic acid level from the jugular vein were compared in both groups at different plase, and perfusion blood distribution and oxygen content difference between the perfused and returned blood were measured in some RCP patients. Results The DHCA time was 35.9 ± 8 min (10. 0 - 63. 0 min) and DHCA+ RCP time was 45.5 ± 17. 2 min (16. 0 - 81. 0 min)The resuscitationtime was 7.1 ± 1.6 h (4.4 - 9.4H)in DHCA patients and 5.4±2.2h(2.0-9.0 h)in RCP patients. Operation death was 3/15 in the DHCA group and 1/50 in the RCP patients. Central nervous complication
