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. 相似文献

In contrast to the majority of renal calculi, in situ extracorporeal shock wave lithotripsy (ESWL) for upper ureteral stones is still controversial. Some centers recommend retrograde mobilization of the calculus into the renal pelvis prior to ESWL as a routine procedure (UC + ESWL). To evaluate the efficiency of in situ ESWL for upper ureteric stones, we initiated a prospective clinical trial. From July 1985 to January 1986, 122 patients presented with upper ureteral calculi, necessitating a total of 146 different procedures: 88 in situ ESWL; 31 UC + ESWL; 15 antegrade ureteroscopies (URS); 6 retrograde URS; 2 open surgery (ureterolithotomy, nephrectomy), and 4 patients were managed conservatively. Of all 99 patients treated at the lithotripter, 80 patients received in situ ESWL (no emergency case, no location problems): in 60 patients (75%) the stone could be disintegrated in one session; 8 patients (10%) required a second ESWL session due to partial fragmentation. Retrograde mobilization using a ureteral catheter or URS was necessary in 9 patients due to failure of in situ ESWL (11%) and, in only 3 patients, we had to remove the stone by antegrade URS (4%). In conclusion, 96% of all upper ureteric stones suitable for primary ESWL could be treated by a noninvasive (in situ ESWL) or minimally invasive (UC + ESWL) procedure. Therefore we recommend in situ ESWL for these calculi. Primary retrograde mobilization is only indicated in case of location problems (stone close to the spine, obesity, skeleton deformation) or emergency cases (colic, hydronephrosis). Antegrade URS should be performed if retrograde mobilization fails or in emergency cases (acute pyelonephritis, following percutaneous nephrostomy, after clinical stabilization). The rate of open surgery is below 2%. 相似文献

With the introduction of a 3-T scanner, magnetic resonance urography (MRU) may be an alternative imaging modality for evaluation of acute renal colic. We performed a prospective study to compare the performance of computed tomography (CT) with half-Fourier single shot turbo spin-echo (HASTE) MRU in the evaluation of patients with suspected renal colic. Patients presenting to the emergency department with acute renal colic were eligible for inclusion. Following a standard CT stone evaluation, patients underwent a non-contrast HASTE MRU study with a 3-T scanner. The presence of perinephric fluid, hydronephrosis, ureteral obstruction, and calculus was assessed. A total of 22 patients completed the study. Twenty (91 %) were diagnosed with an upper tract stone by radiographic findings. MRU detected a discrete stone in 50 % of the patients with stones detected by CT. Perinephric fluid was noted in 12 MRUs, compared to 7 CTs. Using CT as the reference standard, the combination of stone or perinephric fluid and ureteral dilation gave MRU a sensitivity of 84 %, specificity of 100 %, and accuracy of 86 % (95 % CI 0.72–1.0). HASTE MRU with a 3-T MR scanner can reliably detect the presence of upper urinary tract obstruction. Although CT imaging remains the superior modality with which to detect calculi, MRU detects a greater number of secondary signs of upper tract obstruction. For situations in which the use of ionizing radiation is undesirable, MRU is a reasonable imaging alternative. 相似文献

Imaging characteristics of indinavir calculi 总被引:2,自引:0,他引:2
PURPOSE: Indinavir sulfate is an effective protease inhibitor of the human immunodeficiency virus type 1. Use is associated with a significant incidence of crystallization and stone formation in the urinary tract, and these calculi are not visible on plain radiographs. Previously all urinary stones, including uric acid and matrix, were believed to be radiodense on computerized tomography (CT). We conducted a retrospective study to evaluate the radiographic appearance of indinavir calculi. MATERIALS AND METHODS: Retrospective chart review of 36 patients taking indinavir sulfate and presenting with renal colic was performed with attention to presentation, urinalysis, radiographic evaluation and management. Specifically, imaging characteristics on CT were addressed. RESULTS: All patients complained of ipsilateral flank pain and 35 had nausea and/or vomiting. Of 30 patients with dysuria or urgency the majority had hematuria, and most had pyuria and/or proteinuria. No stones were visualized on abdominal radiography. Diagnosis was confirmed on 1 of 13 excretory urograms and 4 of 11 renal ultrasounds. None of 12 CT scans was diagnostic of renal lithiasis. CONCLUSIONS: Indinavir sulfate is a protease inhibitor with poor solubility and significant urinary excretion. Crystallization and stone formation are demonstrated in as many as 20% of patients taking the medication. Most patients present with flank pain, nausea or vomiting and hematuria. Previously CT was thought to identify all urinary calculi with clarity but it cannot reliably confirm the presence of indinavir calculi. 相似文献

PURPOSE: To investigate the effect of patient age on the stone-free rate (SFR) in patients with urinary stones treated by extracorporeal shock wave lithotripsy (ESWL). PATIENTS AND METHOD: 138 patients with renal calculi and 463 patients with ureteral calculi were treated using the Siemens Lithostar Multiline. Multiple logistic regression was used to investigate the effect of age and other possible predicting factors, i.e., gender, location, size, side, grade of hydronephrosis, symptom at onset and history of urolithiasis, on the SFR at 3 months after treatment. RESULTS: The overall SFR was 77.2%. The SFRs of aged< = 39, 40-49, 50-59, 60-69 and 70 = < years were 87.4%, 84.4%, 75.0%, 71.1% and 66.3%, respectively. The elder patients complained less frequency of pain at onset and showed more frequency of hydronephrosis. Multiple logistic regression analysis revealed that patient age (younger) as well as stone location (middle and distal ureter), size (small), hydronephrosis (mild or less) and symptom (painful) at onset were a independent (better) prognostic factors determining stone clearance after ESWL of upper urinary tract stones. CONCLUSION: The SFR of elder patients showed lower than that of younger ones, however, the former less needed analgesia for ESWL session than the latter. ESWL is convenient, relatively useful for elder patients. 相似文献

In a retrospective analysis the results of extracorporeal shock wave lithotripsy (ESWL) treatment were evaluated in patients
with renal stones according to calyceal localization of treated stones.
The 198 patients who underwent ESWL with the Dornier MPL 9000 were analyzed for success rate, complication rate, residual
fragments, regrowth and recurrence rates. Totally 210 calyceal calculi located in different portions of the kidney have been
comparatively evaluated.
No major complications were noted during or after ESWL. Some minor complications such as flank pain, renal colic, haematuria
were observed. Flank pain was observed during ESWL treatment especially in patients with upper calyceal stones. Although stone-free
and residual fragment rates were similar in pelvic, upper and middle calyces, patients with lower calyceal and pelvicalyceal
stones had high residual fragment rate and lower stone-free rate. Patients with stones in the lower calyces or pelvicalyces
had high recurrence and regrowth rates (p<0.05).
ESWL has been considered as the optimal treatment modality for most upper urinary tract calculi. It is especially effective
in patients with pelvic, upper and middle calyceal stones. Patients with lower calyceal stones often failed to eliminate the
fragments, hence had high recurrence and regrowth rates. 相似文献

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. 相似文献
