PURPOSE: We determined if alpha-blocker therapy promotes expulsion of ureteral stones. MATERIALS AND METHODS: Meta-analysis was performed of randomized clinical trials of alpha-blockers for the treatment of ureteral stones. The primary outcome was overall stone expulsion rate. Risk ratios and risk differences were estimated using DerSimonian and Laird random effects models. RESULTS: Eleven trials (911 participants) met inclusion criteria for this study. Pooled analysis demonstrated significantly increased rates of stone expulsion with alpha-blocker therapy. Compared to patients receiving conservative therapy only, patients receiving conservative therapy plus alpha-blockers were 44% more likely to spontaneously expel the stones (RR 1.44, 95% CI 1.31 to 1.59, p<0.001), and stone expulsion incidence increased significantly (RD 0.28, 95% CI 0.22 to 0.34, p<0.001). Sensitivity and subgroup analyses categorized by specific alpha-blocker, prior use of shock wave lithotripsy and stone size produced similar effect estimates, but were generally less precise due to smaller sample sizes. The largest subgroup of trials (664 participants) studied tamsulosin without prior shock wave lithotripsy (RR 1.44, 95% CI 1.32 to 1.58; RD 0.29, 95% CI 0.23 to 0.35). CONCLUSIONS: alpha-Blocker therapy is associated with significantly increased rates of distal ureteral stone expulsion.  相似文献

Ureteral colic occurs in 24 to 34 per cent of all patients following extracorporeal shock wave lithotripsy. Recent research has shown prostaglandin synthetase inhibitors to be effective in relieving the pain associated with ureteral colic. Our prospective, controlled, double-blind, randomized study was designed to test the efficacy of indomethacin in the prophylactic treatment of pain after extracorporeal shock wave lithotripsy. Patients undergoing extracorporeal shock wave lithotripsy were randomized into 2 groups. Group 1 received 100 mg. indomethacin suppositories twice daily and group 2 received placebo suppositories. After extracorporeal shock wave lithotripsy 2 analgesics were available to the patients: oral co-dydramol or intramuscular pethidine was offered in the normal manner by the nursing staff. The pre-extracorporeal shock wave lithotripsy x-ray was used to make a quantitative estimate of the total stone burden in each patient. The post-extracorporeal shock wave lithotripsy analgesic requirement was used to compare the 2 groups. Of 112 patients recruited to the study 55 received indomethacin and 57 received placebo. The request for analgesia in the 2 groups was not different (28 of 55 and 33 of 57, respectively). However, in the indomethacin group only 6 patients required pethidine (10 doses), compared to 18 (41 doses) in the placebo group. This difference is statistically significant (p less than 0.01). There was no difference between the 2 groups in the occurrence of ureteral steinstrasse. Indomethacin has been shown to be effective in the prophylactic treatment of ureteral colic after lithotripsy.  相似文献

PURPOSE: We studied the various stone, renal and therapy factors that could affect steinstrasse formation after extracorporeal shock wave lithotripsy (ESWL), Dornier Medical Systems Inc., Marietta, Georgia to define the predictive factors for its formation. Thus, steinstrasse could be anticipated and prophylactically avoided. MATERIALS AND METHODS: Between February 1989 and May 1999, 4,634 patients were treated with a Dornier MFL 5000 lithotriptor (Dornier Med Tech, GmbH, Germany). Renal stones were encountered in 3,403 patients and ureteral stones in 1,231. Steinstrasse were recorded in 184 patients, of whom 74 required intervention and formed the "complicated group." All patient data, stone and renal characteristics, and data of ESWL were reviewed. Univariate and multivariate statistical analyses of patients, stones and therapy characteristics in correlation with the incidence of steinstrasse formation were performed to assign the factors that had a significant impact on steinstrasse formation. RESULTS: The overall incidence of steinstrasse was 3.97%. The steinstrasse was in the pelvic ureter in 74% of the cases, lumbar ureter in 21.7% and iliac ureter in 4.3%. Steinstrasse incidence significantly correlated with stone size and site, the power level (kV.) used during therapy and radiological renal features. Steinstrasse was more common with renal stones more than 2 cm. in diameter in a dilated system, especially with the use of high power (greater than 22 kV.) for disintegration. A statistical model was constructed to estimate the risk of steinstrasse formation accurately. CONCLUSIONS: Stone size and site, renal morphology and shock wave energy are the significant predictive factors controlling steinstrasse formation. If a patient has a high probability of steinstrasse formation, close followup with early intervention or prophylactic pre-ESWL ureteral stenting is indicated.  相似文献

Extracorporeal shock wave lithotripsy monotherapy was performed in 642 patients for 1 year with an EDAP-LT01 piezoelectric lithotriptor. Of 642 patients 398 completed extracorporeal shock wave lithotripsy treatment and 244 still are undergoing multiple extracorporeal shock wave lithotripsy sessions. The 398 patients had renal (64.6 per cent) or ureteral (35.4 per cent) stones 0.6 to 4.8 cm. in diameter (mean 1.4 cm.). No general or regional anesthesia was required except in 7 children. Among 398 patients who completed extracorporeal shock wave lithotripsy the rate free of stones was 73.4 per cent and the rate of clinically insignificant residual fragments was 12.8 per cent. The success rate (rate free of calculi plus that of clinically insignificant renal fragments) ranged from 95.6 per cent for stones 0.6 to 1.0 cm. in diameter to 52.6 per cent for stones larger than 3.0 cm. (mean 86.2 per cent). The number of treatment sessions in 343 patients with successful results increased in accordance with the stone size, with an average of 1.6 sessions. Double-J* stents were placed in 7 patients and ureteral catheterization was performed in 11 as post-extracorporeal shock wave lithotripsy adjunctive measures. The steinstrasse phenomenon was noted in 14 patients, of whom only 1 required Double-J stenting. There were no significant complications. Therefore, extracorporeal shock wave lithotripsy monotherapy with the piezoelectric lithotriptor is considered to be a safe and efficient outpatient procedure for the initial treatment of urinary stones regardless of stone sizes.  相似文献

Since August 1985 extracorporeal shock wave lithotripsy has been performed in 39 patients with prevesical ureteral stones, including 3 with steinstrasse after extracorporeal shock wave lithotripsy of kidney stones. Female patients less than 40 years old were excluded because of the theoretical possibility of harm to the ovary by shock waves. Via a modified technique with the patient in a flat position, x-rays and shock waves enter through the foramen obturatum. High total power (high number of shocks and high kilovoltage) led to complete stone disintegration and a success rate of 95 per cent was achieved. While ureterorenoscopy should be more restricted, extracorporeal shock wave lithotripsy is the method of choice for the treatment of distal ureteral stones.  相似文献

The results of 471 extracorporeal shock wave lithotripsy treatments in 465 patients with solitary ureteral stones managed by several different techniques are reported. In situ treatment was performed in 123 cases without instrumentation and in 47 after placement of a ureteral catheter. Retrograde stone manipulation was performed in 245 cases immediately before extracorporeal shock wave lithotripsy and an additional 56 were manipulated with ureteral stent placement at least 1 week before extracorporeal shock wave lithotripsy. The success rate was significantly greater if the stone was manipulated into the kidney before extracorporeal shock wave lithotripsy. Significantly less energy (p less than 0.0001) was required for complete disintegration if the stone was free floating in the kidney. The need for subsequent procedures was significantly less (p less than 0.0001) for stones manipulated successfully into the kidney. Complications were infrequent, with the most common being ureteral perforation in 5.1 per cent of the cases, all of which were managed conservatively. Extracorporeal shock wave lithotripsy is the treatment of choice for proximal ureteral calculi because it is less morbid than percutaneous approaches and provides significantly better results than ureteroscopy. An attempt at manipulation of proximal ureteral calculi back into the kidney should be made before extracorporeal shock wave lithotripsy.  相似文献

We reviewed our experience with extracorporeal shock wave lithotripsy therapy in 138 patients who presented with mid and upper ureteral calculi. In the patients who had successful stone manipulation back into the renal collecting system the success rate was significantly higher compared to that for stones treated primarily within the ureter (92.8 versus 80.8 per cent, p less than 0.05). Among the stones treated within the ureter the success rates appeared to be similar for stones treated in situ (83.3 per cent) compared to those treated when a catheter could be placed alongside the calculus (79.3 per cent). Higher voltage and more shock waves were administered to stones treated within the ureter compared to stones that were manipulated back into the kidney. However, this increase power did not enhance the success rate. In addition, it appears that a plain film of the abdomen obtained within 24 hours of lithotripsy treatment is a good predictor of success as defined by the rate free of stones at 6 weeks of followup. Our results from a community-based multi-use lithotripsy center suggest that ureteral stone manipulation should be attempted before extracorporeal shock wave lithotripsy for mid and upper ureteral calculi.  相似文献

Use of double-pigtail stents in extracorporeal shock wave lithotripsy   总被引:1,自引:0,他引:1  
Double-pigtail stents are placed commonly in patients before extracorporeal shock wave lithotripsy to prevent ureteral obstruction from steinstrasse. The use of double-pigtail stents in lithotripsy patients with a moderate stone burden was studied in a prospective randomized trial. Patients with unilateral renal stone(s) with at least 1 diameter between 7 and 25 mm. were eligible for the study. Fifty patients were randomized to a control or stented group. Double-pigtail stents with an attached suture were placed immediately before extracorporeal shock wave lithotripsy in the stented group. Stents were removed by the patients 1 week after lithotripsy. A survey on pain and associated symptoms was completed by patients at 1 and 14 days after treatment. There was no statistical difference in flank or abdominal pain, nausea, vomiting, temperature or use of analgesics at 1 and 14 days after extracorporeal shock wave lithotripsy in the control and stented groups. All patients in the stented groups complained of side effects attributable to the stent including urinary frequency and urgency, bladder pain, hematuria and flank pain with urination. Of 25 patients with stents 7 (27%) had early removal because of severe irritation, early migration or accidental removal. Among the patients with follow-up x-rays 1 month after treatment 17 of 21 (81%) in the control group and 12 of 19 (63%) in the stented group showed no evidence of remaining stones. The use of double-pigtail stents is not beneficial in patients with a moderate stone burden. Double-pigtail stents are associated with considerable patient discomfort but no decrease in symptomatic ureteral obstruction or final stone eradication rate.  相似文献

INTRODUCTION: We studied the various stone, renal, and therapy factors that could affect steinstrasse formation after shock wave lithotripsy (SWL) to define their predictive value. PATIENTS AND METHODS: Between May 1999 and September 2002, 563 patients were treated with a Stonelight V3 lithotriptor. A steinstrasse was recorded in 46 patients. All patient data, stone and renal characteristics, and data of SWL were reviewed. Statistical analyses of patients, stones, and therapy characteristics in correlation with the incidence of steinstrasse formation were performed to assign factors that had a significant impact on the formation of this complication. RESULTS: The overall incidence of a steinstrasse was 8.17%. The steinstrasse was in the pelvic ureter in 84.3% of the cases, in the iliac ureter in 7.84% of them, and in pelvic and iliac ureter in 7.84% of the patients. The incidence of a steinstrasse significantly correlated with stone size and site. The incidence rates of a steinstrasse in renal stones <1 cm, 1-2 cm, and >2 cm were 4.46, 15.87, and 24.3% respectively. The incidence rates of this complication in ureteral stones <1 cm and 1-2 cm were 3.37 and 9.52%, respectively. The incidence rates of a steinstrasse in stones located in upper calices, middle calices, lower calices, and renal pelvis were 6.12, 10.52, 6.36, and 19.32%, respectively. CONCLUSIONS: Stone size and site are the significant factors predicting the formation of a steinstrasse. If a patient has a high probability of steinstrasse formation, close follow-up with early intervention or prophylactic pre-SWL ureteral stenting is indicated.  相似文献
