ESWL与输尿管镜碎石联合处理上尿路结石

目的：探讨对部分上尿路结石采用ESWI．与输尿管镜碎石联合处理的方法。方法：对70例上尿路结石患者采用ESWI。与输尿管镜下钬激光碎石（URS）联合交替治疗。其中输尿管结石48例,。肾结石22例。结果：结石总排净率为91．4％00（64／70）,其中输尿管结石排净率为95．8％（46／48）,肾结石排净率为81．8％（18／22）。3例治疗失败,其中1例输尿管结石因输尿管狭窄无法入镜;另2例肾结石,1例因交替治疗次数过多中途停止治疗,1例因结石硬度过大ESWI,不佳,均改为PCNL术。结论：ESW[。与URS联合交替进行的疗法处理上尿路结石,避免了创伤性治疗,扩大了ESWI,治疗范围,降低了URS手术难度,缩短了URS操作时间,提高了结石排净率,患者创伤微小、恢复快、并发症少,是治疗上尿路结石,特别是部分复杂性上尿路结石较理想的方法之一。     

Clinical experiences of renal and ureteral stones by extracorporeal shock-wave lithotripsy (ESWL). IV: 3-year clinical experience of cases treated with ESWL

We report our 3-year experience with extracorporeal shock wave lithotripsy (ESWL) since we first used it for upper urinary tract stones on September 1st, 1984. A total of 1,225 patients (1,320 cases) underwent 1,647 sessions with ESWL; They consisted of 855 males (70%) and 370 females (30%). Treated stone locations were 593 renal stones, which contained 112 complete staghorn calculi, 504 ureteral stones, 110 renoureteral stones, and 1 bladder stone. ESWL monotherapy was performed on 90% of cases with renal and ureteral stones, and 46% of cases with complete staghorn calculi. In all the cases so far observed for more than 12 weeks after ESWL, 84.9% of the former showed complete discharge of the stones, and 0.7% showed no change. Only 48.9% of the later showed the complete discharge of the stones, 43.3% of which had residual stones, and 7.8% had fragments of the size of small beans. Complications, which were fever and pain, were noticed in 33.6% of the cases with renal and ureteral stones, and 64.3% of the cases with complete staghorn calculi. After ESWL, hematuria was noticed in almost cases, but the average volume of hemorrhage was 28 +/- 33 ml/day. The only contraindication of ESWL was severe obesity, and in the cases in which spontaneous stone discharge can be expected.

Extracorporeal shock wave lithotripsy in children. Efficacy, complications and long-term follow-up.

OBJECTIVES: Extracorporeal shock wave lithotripsy (ESWL) is effective and safe for the treatment of upper urinary tract calculi in adults. Some speculations concerning possible damages from ESWL on the growing kidney have been raised. METHODS: From January 1990 to December 1998, 64 children (30 girls and 34 boys; 8 months to 15 years old, mean 5.6 years) with a total of 83 stones of the upper urinary tract were treated by ESWL (Lithostar). Preoperative evaluation included history, physical examination, routine blood tests, urinalysis, urine culture, intravenous urography and optional renal scintigraphy. The impulse rate per treatment varied from 750 to 4,000 (mean 2,996). After acute treatment, routine follow-up included renal ultrasound, blood pressure controls, laboratory tests and eventually plain film X-ray. RESULTS: Successful fragmentation of the stones was achieved in all patients. In 54% the patients were free of stones treated at the time of discharge. At 3 months after treatment radiographic studies showed no residual fragments in 80% of the treated children. 83% of the treated stones were cleared entirely. The remaining fragments were clinically insignificant. An average of 2.5 ESWL treatments per child in general anesthesia were required. Stone analysis showed 20 calcium oxalate, 38 calcium phosphate, 12 struvite, 2 uric acid and 9 cystine calculi. Ureteral stents were placed in 43%. No significant urinary infection was seen under antibiotic prophylaxis. Only 3 children showed a recurrence (1 x cystinuria with low compliance and 2 x struvite). There was no case of renal scarring. No change in renal function or blood pressure was found compared to the preoperative values. Hematuria and proteinuria disappeared in all children who were free of stones. Renal ultrasound revealed no growth difference between treated and untreated renal units. CONCLUSIONS: In childhood, ESWL is an efficacious and safe treatment of stones of the upper urinary tract. The long-term follow-up after ESWL with a second-generation lithotriptor did not show any signs of damage to the growing kidney. Sometimes repeated ESWL treatments are justified by the low rate of complications.     

Extracorporeal shock-wave lithotripsy (ESWL) monotherapy for stones in lower ureter.

Extracorporeal shock-wave lithotripsy (ESWL) has been accepted as the method of choice for most upper urinary tract calculi. However, in cases of stones in the lower ureter, ureteroscopic procedures have generally been preferred. Using the Dornier HM3 lithotriptor with modifications in the patient's position, we were able to successfully treat 155 unselected cases of lower ureteral calculi. The average stone size was 9.6 mm (range 5-23 mm). One hundred forty-three patients had stones located below the lower margin of the sacroiliac joint. These patients were placed in a supine position. The stones were visualized radiologically without use of a ureteral catheter in 78 percent of the patients; in 22 percent a ureteral catheter was inserted prior to ESWL to aid in stone localization. In 145 patients (94%) treatment was completed in one session; 10 patients (6%) required two sessions. Of the patients, 38 percent were free of stones one day after ESWL; 97 percent became stone free within three months, and only 3 patients required endoscopic manipulation, after ESWL. Twelve patients had stones in the midureter overlying the sacroileum. They were placed in the prone position, and the calculi were visualized with the aid of a ureteral catheter. All these patients became free of stones one month after treatment. There were no significant treatment-related complications except for bacteremia in 1 case. In view of the remarkable efficacy, negligible complication rate, and shorter hospital stay as compared to ureteroscopic stone manipulations, we recommend high energy ESWL as the primary monotherapy of mid and lower ureteral stones.

纤维胆道镜在上尿路结石手术中的应用

目的:探讨纤维胆道镜在上尿路结石手术中的应用价值。方法:为31例复杂上尿路结石(多发肾结石、输尿管多发结石、输尿管结石并肾结石)患者施行手术,5例输尿管切开取石术中结石移位时应用纤维胆道镜协助取石。结果:35例取石成功,1例多发肾结石患者有2颗结石残留于肾盏内,术后2个月体外冲击波碎石术(extracorporeal shock wave lithotripsy,ESWL)治疗后排出,2例输尿管粘膜和1例肾盂粘膜损伤出血。结论:纤维胆道镜用于上尿路结石手术,尤其是复杂性上尿路结石手术,有助于取尽结石,对患者损伤小,是一种安全有效的方法,值得临床推广应用。     

Treatment of 2019 cases with upper urinary tract calculi using a piezoelectric lithotriptor ESL-500A

PURPOSE: We evaluated the results of extracorporeal shock wave lithotripsy (ESWL) in a large number of cases with upper urinary tract calculi, and reported the strategy how to improve the efficacy and safety of ESWL. PATIENTS AND METHOD: Eight hundred fifteen patients with renal calculi and 1,204 patients with ureteral calculi were treated using a piezoelectric ultrasound-guided lithotriptor, Toshiba ESL-500A. Auxiliary measures were needed in 51 cases (2.5%) and 1,968 cases (97.5%) were treated by in situ procedures. ESWL was performed with the optimal positioning of the patient and under the continuous monitoring by ultrasound system. The visibility of stones was improved by removal of abdominal gas and administration of diuretic agent to dilate the ureter. Cases with urinary tract infection were medicated by antibiotics and the obstruction of the urinary tract was cleared away as soon as possible. RESULTS: Including the cases with residual fragments less than 4 mm, the success rates at one month after the treatment were 97.7% and 98.7% for the renal and ureteral calculi, respectively. The mean numbers of sessions were 1.49 for renal calculi and 1.16 for ureteral calculi. Multiple sessions were required in 24.2% of renal calculi and 12.0% of ureteral calculi. No serious complication has been observed except for three cases, which were sepsis after ESWL, anuria in a solitary kidney, and pyonephrosis caused by Steinstrasse with urinary infection, respectively. CONCLUSION: ESWL using ESL-500A is an efficient treatment of upper urinary tract calculi which has higher pulverization rate and fewer complications in the adequate procedure.     

Treatment of ureteral stone disease: the role of ESWL and endourology

Summary In recent years, extracorporeal shockwave lithotripsy (ESWL) has proved a safe and easily reproducible method for the treatment of calculi in the upper urinary tract above the iliac crest. Current indications for ESWL as single therapy encompass approximately 60%–70% of all stones. The use of endourological methods as auxiliary procedures can enhance the range of indications to 95% of all renal stones and 85% of all ureteral stones. In the last year, 1340 patients have been successfully treated for urinary calculi at our department. Evaluation of all stone cases shows that ESWL alone, ESWL combined with percutaneous techniques, or percutaneous techniques alone were performed on 93% of all patients. Only 7% of patients had to undergo open surgical treatment, 1% for renal stones and 15% for ureteral stones. Ureteral stones are still among the problem stones for ESWL, in many cases requiring time-consuming combined procedures with either of the percutaneous methods. Furthermore, ureteral obstruction caused by stone particles as a complication after ESWL-treatment of large renal stones has to be relieved using percutaneous techniques. In this report we describe our approach in detail and discuss our results.     

逆行插管与静脉造影定位ESWL治疗上尿路阴性结石的比较

为探讨不同部位上尿路阴性结石定位方法的选择，对９８例上尿路阴性结石患者采用大剂量静脉尿路造影（ＩＶＵ）和逆行插管（ＲＧＰ）定位法行体外冲击波碎石术（ＥＳＷＬ），并根据其疗效进行比较。结果：２０例肾阴性结石中，８例行ＩＶＵ定位下ＥＳＷＬ碎石，治愈率为１２．５％；１２例行ＲＧＰ定位下ＥＳＷＬ碎石，治愈率为８．３％；认为对此类患者不宜行Ｘ线定位碎石。５８例输尿管上、中段阴性结石中，２８例行ＩＶＵ定位碎石     

Clinical application of Therasonic lithotripsy treatment system for upper urinary tract calculi

Extracorporeal shock wave lithotripsy (ESWL) using a Therasonic lithotripter was performed on 30 patients with urinary tract calculi between July, 1989 and February, 1990. The results obtained in 31 cases (one patient had bilateral renal stones) were presented. There were 22 inpatients and 8 outpatients in this series. The stone location was: renal pelvis in 15 cases, renal calyces in 10 cases, parenchyma or diverticulum of renal calyces in 3 cases, ureteropelvic junction in 1 case, and upper ureter in 2 cases. Sixteen cases (52%) became stone-free and residual stones (less than or equal to 4 mm) remained in 9 cases (overall effective rate 81%) at one month after the treatment. There were no serious complications including bacteremia and renal hematoma. We concluded that Therasonic lithotripter is useful in the management of upper urinary tract calculi.     

Retrograde ureteroscopy for distal ureteric stone removal in children

OBJECTIVE: To compare the efficacy and safety of ureteroscopy plus intracorporeal lithotripsy (ULT) with extracorporeal shock wave lithotripsy (ESWL) for treating distal ureteric calculi in childhood, as such stones are commonly treated by ESWL as the first option in adults but there is no agreement on the method of treating them in children. PATIENTS AND METHODS: From July 2002 to July 2003, children presenting with ureteric stones were consecutively randomized for treatment using ULT or ESWL. The two groups were matched for age, sex and stone position in the distal ureter. A 7.5 F ureteroscope combined with a ballistic lithotripter or holmium-YAG laser was used for ULT. ESWL was administered using a second-generation lithotripter. The success rate, effectiveness quotient, complication rate and hospitalization were evaluated and compared using Student's t-test (chi-square) and Fisher's exact test as appropriate. In all, 31 patients (21 girls and 10 boys, mean age 7.2 years, range 2-17) were treated, by ULT in 17 (12 girls and five boys) and ESWL as a primary procedure in 14 (five boys and nine girls). RESULTS: After one ULT, all the girls and four boys, and after ESWL, four girls and two boys, were rendered stone-free at the first treatment. The total stone-free rate was 16 of 17 for ULT and six of 14 for ESWL (P = 0.004). Eight patients had a second ESWL and three then became stone-free. The five patients in whom both ESWL treatments failed had a successful ULT. There was no significant difference between the groups in complication rate and hospitalization. General anaesthesia was required in all patients <12 years old treated by ULT or ESWL. The calculated efficiency quotient for treating distal ureteric calculi was significantly lower for ESWL than ULT (P < 0.05). CONCLUSIONS: ULT should be recommended as the treatment of choice for distal ureteric calculi in children; using small ureteroscopes the target stone was treated safely and effectively.

Extracorporeal shockwave lithotripsy, endourology and open surgery: the management and follow-up of 200 patients with urinary calculi

The management and follow up of 200 consecutive patients with renal and ureteric calculi are presented. The primary treatment of 185 (92.5%) was by extracorporeal shockwave lithotripsy (ESWL), of whom three (1.6)%) with large calculi underwent percutaneous nephrolithotripsy (PCNL) prior to ESWL as a planned combined procedure. Twelve (6%) were treated by PCNL or ureterorenoscopy (URS) as their definitive treatment and three (1.5%) by conventional open renal and ureteric surgery. The average in-patient stay was 3.8 days and most returned to normal activity within one day of discharge. Of the 185 patients 102 (55%) required no analgesia after treatment by ESWL, 29 (15.6%) required parenteral analgesia and the rest were comfortable with oral non-narcotic medication. Thirty (16%) required auxillary treatment by percutaneous nephrostomy (PCN), PCNL and URS following ESWL for obstructive complications from stone particles. Two required further ESWL and one PCNL at three months for large fragments. Overall, open surgery was required for only 1% of renal calculi and 13% of ureteric stones. These results are consistant with the extensive West German experience confirming that most urinary calculi are now best managed by ESWL and endoscopic techniques. Where these facilities are available open surgery should only be necessary for less than 5% of upper urinary tract stones.     

Ureteral calculi in children: review of 50 consecutive cases

Fifty children presenting with ureteral calculi over a twenty-year period were studied retrospectively. There were 35 boys and 15 girls, with a mean age of five and a half years. Nineteen patients had a urinary tract anomaly: 11 had an obstructed megaureter, and 8 had previously undergone urinary tract surgery. Forty-four children had infection stones and the remaining 6 oxalate calculi. Infected urine was found in 35; the infecting organism was a Proteus species in 23. Metabolic abnormalities were detected in 2 children. Operative removal of the stones was done in 39 patients, and in the remaining 11 patients the stones passed spontaneously. There were 6 recurrences, all within four years of initial presentation.     

Clinical experience with extracorporeal shock wave lithotripsy (ESWL) in upper urinary tract stones

We treated 100 patients of upper urinary tract stone using extracorporeal shock wave lithotripsy (ESWL), from April to October 1986. Eighty-six of the patients were treated by ESWL monotherapy, and the other cases required further treatment, such as percutaneous nephrostomy (PCN), percutaneous nephrolithotomy (PNL), and transurethral ureterolithotripsy (TUL). On the X-ray film obtained from one to three months after ESWL, 73 patients had no stones, 8 patients had sandy stones, 7 patients had small fragments less than 5 mm, 2 patients had large stones equal to or greater than 5 mm and 10 patients could not be followed up. Therefore, 97.7% of all patients were successfully treated. In conclusion, ESWL is considered to be an ideal method to treat upper urinary tract stones, and soon will become the first choice of treatment of urolithiasis together with the progress in endourological techniques.     

延安地区泌尿系结石成分分析的研究

目的利用红外光谱法测定延安大学附属医院泌尿外科手术获得的泌尿系结石成分,探讨延安地区泌尿系结石成分与年龄、性别等关系,比较上、下尿路结石成分特点,分析延安地区泌尿系结石发生的流行病学情况,为临床制定有效的个体化治疗及预防措施提供参考依据。方法收集2013年1月至2017年1月在延安大学附属医院泌尿外科治疗1984例尿路结石患者的年龄、性别、结石部位等临床资料,对比分析延安地区泌尿系结石在不同年龄、不同性别、不同解剖部位的分布特点。结果在1984例泌尿系结石的患者中,按每10岁年龄大小分组排序,统计各年龄阶段泌尿系结石发病情况,男性患者有1346例,女性患者有638例,男性年龄(50.23±14.48)岁,女性年龄(47.87±14.51)岁,男、女患者比例约2.11∶1。在66~75岁年龄段,尿路结石发病率性别差异具有统计学意义(P<0.05)。结石成分以混合性结石为主,以混合性结石为主,共1582例,占79.76%。其中1665例(83.92%)为上尿路结石,上、下尿路结石的比例为5.22∶1,其余为肾结石合并膀胱结石。上尿路结石中男性1062例,女性603例,男女比例为1.76∶1;下尿路结石中男性284例,女性35例,男女比例为8.11∶1。青壮年(年龄≤45岁)泌尿系结石患者草酸钙为主结石、感染性结石多见;中老年(年龄>45岁)泌尿系结石者草酸钙为主结石、尿酸类结石多见。感染性结石患者性别差异具有统计学意义(P<0.05)。结论在延安地区男性较女性更容易患泌尿系结石。同时,不同年龄段结石构成成分具有差异。对于年龄≤45岁患者,主要以草酸钙为主结石、感染性结石多见,这与结石整体发病率基本一致;而对于年龄>45岁患者,主要以草酸钙为主结石、尿酸性结石多见。表明对于不同年龄段的结石患者,可以根据上述结果在结石的预防和治疗上综合考量,给予明确而更加合理的治疗。
