Clinical experience of in situ extracorporeal shock wave lithotripsy using ESL-500A for bilateral ureteral stones and ureteral stones in a solitary, or a functionally solitary kidney]

Extracorporeal shock wave lithotripsy (ESWL) using ESL-500A was performed for the treatment of 18 cases of bilateral ureteral stones and 3 cases of a solitary or a functionally solitary kidney with ureteral stones from September 1991 to February 2000. Sixteen cases of the former and all 3 cases of the latter were treated by in situ ESWL, and the other 2 cases of bilateral ureteral stones were treated with auxiliary procedures. No residual stones were observed in any cases except for one of bilateral ureteral stones treated by in situ ESWL. The results show that in situ ESWL using ESL-500A seems to be useful for the treatment of bilateral ureteral stones and ureteral stones in a solitary kidney, including a functionally solitary kidney. However, auxiliary treatment will be needed in cases of urinary tract infection, undetectable stones by ultrasonography, or bilateral large stones.

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.     

上尿路结石的手术方式选择(附2 528例临床报告)

目的分析上尿路结石的各种手术方式，探讨临床治疗中合理的术式选择。方法回顾性分析1997年2004年收治的2528例上尿路结行患者的临床分类、手术方式及并发症。结果单纯性肾结石和输尿管上段结石以ESWL治疗为主，3个月内结石排净率为86％。5％形成石街，9％经2—3次ESWL治疗无排石现象，转手术率14％；中、下段结石采用输尿管镜下气压弹道碎石治疗为主，结石排净率为92％。经皮肾穿肾镜取石，肾盂和输尿管上段结石的取净率为100％；鹿角形结石的取净率为95％；复杂性肾结右选择升放性手术取石或联合方式治疗为主，因肾脏无功能而行一侧肾切除7例（1．6％），下术后输尿管漏7例，切口经久不愈3例，肾脏大出血5例，无死亡病例。结论上尿路结石的微创手术可以避免开放于术对患者造成的痛苦，减少术后并发症，但也不能盲目采用，对于复杂性结石，开放手术仍有实际应用价值。     

Primary extracorporeal shock wave lithotripsy of staghorn renal calculi.

186 patients with partial and 55 patients with complete renal staghorn calculi were treated with primary extracorporeal shock wave lithotripsy (ESWL) at the Department of Urology, University of Würzburg Medical School. Partial staghorn calculi required an average of 1.4, complete staghorn calculi an average of 2.2 treatment sessions using the Dornier HM 3 lithotriptor. 55% of all patients and 46% of the patients with complete staghorn calculi were rendered stone-free within 1 year after ESWL. Pretreatment urinary tract infections present in 50.6% of all patients could be reduced to 22.5% 1 year after ESWL. The most frequent complications after ESWL were ureteral obstruction caused by 'steinstrasse' (41.4%), fever (38.4%), and renal colics (29.4%). Severe complications needing open operative procedures or blood transfusions did not occur. 50% of all patients underwent auxiliary procedures (e.g. insertion of indwelling ureteral stents: 25.3%, percutaneous nephrostomy: 20.3%, percutaneous nephrolithotripsy: 2.9%). Pretreatment insertion of an indwelling ureteral stent was found to reduce posttreatment complications as well as the need for percutaneous nephrostomy only in patients with partial staghorn calculi. The data presented in this study demonstrate that primary ESWL therapy can be safely and successfully performed in the majority of patients with renal staghorn calculi. In patients requiring complete removal of all stone fragments, a percutaneous lithotripsy can be performed following ESWL.     

Electromagnetic extracorporeal shock wave lithotripsy in children

Extracorporeal shock wave lithotripsy (ESWL) was performed for the treatment of urinary tract calculi in 28 children. All treatments were done with the standard Siemens Lithostar device in situ: no special adaptations for adequate positioning of children are required to target the stone precisely. A total of 42 calculi in 30 renal units was treated, requiring 50 ESWL sessions. The mean energy used was 16.4 kv. and the number of shock waves averaged 3,188. Mean fluoroscopy time per session was 1.5 minutes. In 26 of 50 sessions (52%) general anesthesia was needed for the child to remain perfectly still. A complete stone-free rate was achieved in 38 of 42 calculi (90.5%): after 1 session in 30 (71.4%), after 2 sessions in 6 (13.7%) and after 3 sessions in 2 (4.8%). Five staghorn calculi were treated with ESWL monotherapy. A complete stone-free result was obtained after 3 treatments in 2 patients, while 2 had residual fragments in the lower pole (5 mm. after 6 sessions and 11 months of followup in 1, and 7 mm. after 3 sessions and 3 months of followup in 1). A cystine staghorn stone necessitated open nephrolithotomy after 3 sessions without any fragmentation. One impacted sacroiliac ureteral stone required endoscopic laser lithotripsy. Except for these 2 failures no adjuvant procedures were needed. There were no intraoperative or postoperative complications and minor skin bruising at the coupling site after 3 treatments did not require any therapy. We conclude that electromagnetic ESWL with the standard Lithostar unit is a safe and effective method to treat calculi throughout the urinary tract in children.     

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.     

Extracorporeal shock wave lithotripsy in children: experience using a mpl-9000 lithotriptor

Our objectives were to assess the value of extracorporeal shock wave lithotripsy (ESWL) in treating pediatric urolithiasis, and to determine the factors that may affect treatment success. Between January 1993 and August 2002, 129 children with upper urinary tract calculi (134 renoureteral units) were treated using a Dornier MPL-9000 lithotriptor. The series consisted of 77 boys and 52 girls with an age range from 20 months to 14 years (average age: 8.7 years). All ESWL procedures took place under general anaesthesia or sedation with ketamin or fentanyl. Under ultrasonic or fluoroscopic guidance, children were treated with a maximum 2,550 shocks at an average of 19.5 kV. Success was defined as the lack of any visible stone fragments on post-treatment radiological evaluation. The patients were assessed 3 months after ESWL treatment and the results were compared using ²-tests to detect factors that might be associated with treatment success. There were 105 renal, 20 ureteral, four bilateral renal and one unilateral renal plus contralateral ureteral calculi. The mean sizes were 15.7 mm for pelvic, 17.8 mm for renal and 10.2 mm for ureteral stones. One or two lithotripsy sessions were sufficient in most cases (71.6%). In 15 (11.6%) patients, double J stents introduced before lithotripsy were left indwelling until all stone fragments were voided. Overall success rates were 89.5% for pelvic, 85.5% for renal and 75% for ureteral stones. Complications such as urinary tract infection, Steinstrasse and small subcapsular hematoma occurred in 19 (14.7%) patients. The only significant factor associated with the stone-free rate was the diameter of the stone (P=0.022). This study confirmed that the stone-free rate is significantly influenced by stone size. Because children with stone disease are at risk for a longer period than adults, their cumulative likelihood of stone recurrences may be higher. Thus, we agree with other authorities that minimally invasive treatment, such as ESWL, is mandatory in children with urolithiasis.     

Clinical experience of extracorporeal shock wave lithotripsy for cystine calculi

Thirty patients (16 men and 14 women) with cystine urinary stones were treated by extracorporeal shock wave lithotripsy (Dormer HM-3) from December 1984 through October 1989. The average patient age was 35.2 years with a range of 14 to 59 years. Seventy per cent of these subjects had had previous open surgical operations for stones. The cases consisted of 7 ureteral stones and 37 renal stones, including 15 staghorn calculi. An average of 1.3 session of ESWL was carried out to treat ureteral stones. Thirty-seven renal units with renal stone required 96 sessions of lithotripsy (average 2.6 sessions per unit). Seven patients with ureteral stones required auxiliary procedures, i.e., one transurethral lithotripsy (TUL), two percutaneous nephrostomies (PNS) and one open surgery. Thirty-seven renal stones, including staghorn calculi was treated by ESWL and auxiliary treatment of 21 TUL procedures, one PNS, 16 PNL procedures and one chemical chemolysis. Successful fragmentation (residual debris less than or equal to 4 mm) was achieved in 85.7% of ureteral stones, 90.9% of renal stones and 73.3% of staghorn calculi. The stone free rates of patients with ureteral stones, renal stones and staghorn calculi were 71.4%, 50.0% and 53.5%, respectively, at 3 months after ESWL. No serious complications were seen in this series. Fever above 38.5 degrees C was the most common complications (13.5%). Ureteral perforation was encountered once in TUL procedures. Transfusion and selective arterial embolization were needed for one case treated by PNL procedures. Although cystine stone is harder to be fragmented by ESWL than other stone composition, ESWL and endourology may be effective and safe procedures for cystine stone patients.(ABSTRACT TRUNCATED AT 250 WORDS)

Changing modality of the treatment in upper urinary tract calculi. Percutaneous nephrolithotripsy and transurethro-ureteral lithotripsy

From March, 1984 to April, 1985, 70 cases of upper urinary tract calculi (73 renal units) were treated by percutaneous nephrolithotripsy or transurethro-ureteral lithotripsy, mainly utilizing ultrasonic lithotrite. While in the early period of treatment, two stage procedure of creation of nephrostomy tract and percutaneous nephrolithotripsy was performed for renal and upper or middle part of the ureteral calculi, one stage procedure, nephrostomy tract formation followed by ultrasonic nephrolithotripsy is commonly used in recent cases. During this period, conventional stone surgery was seen in 6 cases of pyelolithotomy and 2 of ureterolithotomy, while 52 cases of stone surgery were performed during the earlier period (from January, 1983 to February, 1984). Renal and upper or middle part of ureteral calculi were successfully removed in 49 out of 58 cases (84.5%). Most of the patients required 1 or 2 trials of percutaneous nephrolithotripsy. Middle or lower part of ureteral calculi were removed in transurethro-ureteral approach in 11 of the 12 cases. Hematuria and fever were most common complications after treatment and 3 patients required blood transfusion after 3 or 4 sessions of nephrolithotripsy. Percutaneous nephrolithotripsy and transurethro-ureteral lithotripsy are now widely used for treatment of upper urinary tract calculi, replacing the conventional surgical treatment. Moreover, very recently, extracorporeal shock wave lithotripsy is available in Japan. To the patients with renal calculi indicative of this treatment, both percutaneous nephrolithotripsy and extracorporeal shock wave lithotripsy are introduced and either way of treatment can be chosen by the patient himself.     

Extracorporeal shock-wave lithotripsy (ESWL) of pelvic kidney calculus. Use of C-arm fluoroscopy for correct patient positioning

Extracorporeal shock-wave lithotripsy (ESWL) is the preferred treatment modality for renal and upper ureteral calculi. It is usually reserved, however, for urinary tract calculi above the iliac crest of the bony pelvis. A calyx calculus in a pelvic kidney was successfully treated with ESWL by using a C-arm fluoroscope to simulate the exact direction of the shock waves. The patient was then positioned so that the shock waves entered below the sacrosciatic notch. This same technique of exact patient positioning may have application in the treatment of some lower ureteral calculi.
