The purpose of the study is to evaluate the outcomes of semirigid ureterorenoscopy and intracorporeal lithotripsy as a definitive
treatment in pregnant women with obstructive ureteral calculi. A retrospective analysis was performed of 16 pregnant patients
referred to gynecology department with ureteral obstruction from 2007 to 2009. The mean age was 25 years, and mean gestation
period was 30 weeks. Of the 16 patients; 50% had fever, 100% flank pain, 56% dysuria, 25% gross hematuria, 50% positive urine
culture, and 75% pyuria and microscopic hematuria. Abdominal ultrasonography was the principle diagnostic test used. The mean
stone size was 9.45 mm. Eleven of the 16 patients, 54% had stones located in the distal ureter and 46% proximal ureter. The
stones were fragmented using a swiss pneumatic lithoclast through 9.5 F semirigid ureteroscope by 0.035 mm safety guidewire
with the patient under general anesthesia. Eleven patients had obstruction due to the ureteral calculi. Eight of 11 patients
had complete fragmentation of the calculi by ureteroscopy as a primary treatment. Push-back was performed in the other three
patients. By applying Dj catheter, and performing eswl after giving birth, the patient became stone-free. Dj catheter was
applied peroperative to all 16 patients. No complications were recorded, and all patients completed the full term of pregnancy.
The results of our study have shown that semirigid ureteroscopy to diagnose ureteral calculi and treat them with intracorporeal
pneumatic lithotripsy and ureteral stent insertion, as indicated, is the most efficient and definitive treatment modality
in pregnant women. 相似文献

PURPOSE: Although new forms of lithotripsy, such as new-generation shockwave and laser lithotripsies, have recently been developed, the optimal treatment for impacted ureteral stones (IUS) remains controversial. We investigated, retrospectively, the outcome of IUS treated with ureteroscopic pneumatic lithotripsy. PATIENTS AND METHODS: Twenty-two IUS cases were treated using ureteroscopic pneumatic lithotripsy. Of 22 stones, 8 (36%) were treated by ureteroscopic pneumatic lithotripsy as initial treatment and 14 (64%) with pneumatic lithotripsy as an auxiliary treatment after SWL. The stone sizes ranged from 7 to 16 mm with 14 located in the proximal, 3 in the middle, and 5 in the distal ureter. RESULTS: Twenty stones (91%) were effectively fragmented by ureteroscopic pneumatic lithotripsy and eliminated within 1 month after treatment. One stone could not be observed with the ureteroscope secondary to the kinking and stricture of the ureter under the stone, and the stone moved into the kidney during the procedure. The stone was subsequently treated successfully with SWL. One other stone was first fragmented into two pieces; and one big piece, which migrated into the kidney, was treated successfully with SWL. Complications such as bleeding, ureteral injury, and perforation did not occur. Although a few small fragments migrated into the kidney during the procedure in three cases, the overall stone-free rate at 1 month after a one-session treatment with pneumatic lithotripsy was 91%. CONCLUSION: Impacted ureteral stones can be treated effectively with ureteroscopic pneumatic lithotripsy in both the short and the long term. 相似文献

PURPOSE: To present our clinic experience with the Swiss Lithoclast pneumatic lithotripter in the endoscopic management of urinary calculi. PATIENTS AND METHODS: From August 1994 to December 1997, 145 patients with ureteral calculi and 5 patients with urethral calculi were treated with the Swiss Lithoclast. RESULTS: In the ureteral stone group, ureteroscopic addressing of the stones was successful in 133 patients. In 27 patients, the stones were partially fragmented and remained in situ or were pushed back to the calices. They were subsequently treated successfully with SWL. Stones were fragmented in a single session in 101 cases. Complications associated with the procedure included five perforations and four urinary tract infections. All of the five urethral stone patients were treated successfully with pneumatic lithotripsy. The overall successful fragmentation rate thus was 70.7% (106 of 150) and 88.7% (133 of 150) in combination with adjuvant SWL. CONCLUSIONS: We have found Swiss Lithoclast pneumatic lithotripsy to be a safe, effective, and economical treatment method for urinary calculi. If combined with other modalities such as SWL, this treatment will be even more effective. 相似文献

Ureteroscopic treatment of ureteral lithiasis with pneumatic lithotripsy: analysis of 287 procedures in a public hospital 总被引:6,自引:0,他引:6
Ureteroscopes and different lithotripsy methods have greatly improved the urologists ability to treat ureteral stones, regardless of their location in the ureter. We retrospectively reviewed our experience with ureteroscopic pneumatic lithotriptor in 287 patients with ureteral calculi. Ureteroscopic stone treatment was performed between October 1999 and May 2004. Of 221 patients with distal ureteral calculi, 209 (group 1), and 58 of 66 patients with upper ureteral calculi (group 2) were treated successfully by ureteroscopy alone. In group 1, seven migrated stones (to the upper urinary tract) were successfully treated by ESWL later. There were five-treatment failures due to ureteral perforation which consequently required open ureterolithotomy. In group 2, there were five patients with migrated stones; two of them were sent to a percutaneous nephrolithotomy center because of previously unsuccessful ESWL attempts. Three of these with migrated stones were treated by ESWL later. In three patients, we switched to open ureterolithotomy because of ureteral rupture that required surgical repair. Ureteroscopic pneumatic lithotripsy is a safe and effective treatment modality for ureteral calculi. 相似文献

Management of the impacted ureteral calculus 总被引:8,自引:0,他引:8
The management of 42 impacted ureteral calculi is reviewed. Impacted stones were defined by the inability to pass a guide wire or catheter on initial attempts. Stones were impacted in the upper ureter in 10 patients, mid ureter in 11 and lower ureter in 21. Upper ureteral stones were treated in 8 patients by extracorporeal shock wave lithotripsy after disimpaction by laser or other techniques. Mid ureteral stones were treated by laser alone in 7 patients and by extracorporeal shock wave lithotripsy after disimpaction in 4. Lower stones were treated by laser in 17 patients and ultrasound in 2. Complications included 3 major and 5 minor perforations, and 4 false passages. Treatment was successful without an open operation in 40 of 42 patients (95%). Our current approach to impacted ureteral calculi involves passing a rigid ureteroscope to the stone, with disimpaction performed by laser fragmentation or other dislodgement maneuvers. Proximal stones or large fragments then are treated by extracorporeal shock wave lithotripsy. Mid ureteral stones are treated similarly, unless they are so fragile that in situ fragmentation may be completed easily. Lower ureteral stones are fragmented in situ, with hard fragments extracted by basket. Alternative treatments for impacted calculi at all levels include unstented in situ extracorporeal shock wave lithotripsy, antegrade ureteroscopy and, finally, an operation. 相似文献

Extracorporeal shock-wave versus pneumatic ureteroscopic lithotripsy in treatment of lower ureteral calculi 总被引:5,自引:0,他引:5
Aim: To compare the efficacy and complications of extracorporeal shock-wave lithotripsy (SWL) and pneumatic ureteroscopic lithotripsy (URS) in the treatment of lower ureteral calculi. Methods: From August 1997 to June 1999, 210 patients with calculi in the distal third of the ureter were treated with SWL and the other 180 with URS. The stones were fragmented with either HB-ESWL-V lithotripter or JML-93 pneumatic lithotripter through Wolf 7.5~9.0 Fr ureteroscope. The outcome was assessed in terms of stone clearance rate, re-treatment rate and complication incidence. Results: The stone clearance rate was 78.1% with SWL and 93.3 % with URS (P<0.05). SWL had a re-treatment rate of 11.9 %, vs 2.2 % in the URS group (P<.05). URS caused ureteral perforation in 3.3% of patients, while it was 0 with SWL (P<0.05). The differences in the incidence of other complications such as infection and stricture between the two groups were insignificant. Conclusion: Though the selection of these two options depends on equip 相似文献

PURPOSE: To evaluate the efficacy and safety of rigid ureteroscopy for the treatment ureteral calculi in children. PATIENTS AND METHODS: Between January 2002 and January 2006, 16 boys and 25 girls with an average age of 9.5 years (range 3-15 years) were treated with a 95F rigid ureteroscope for stones 4 to 10 mm (mean 5.6 mm) in 46 renoureteral units (RUUs), and the results were evaluated. The stones were located in the upper ureter in 4 RUUs, the middle ureter in 15, and the lower ureter in 27. Dilatation of a tight ureteral orifice was necessary in 17 cases (36.9%). RESULTS: On examination during ureteroscopy, all calculi were well fragmented, and in 33 patients (94%), stone fragments were removed directly. Stones were fragmented with pneumatic lithotripsy in 23 RUUs and removed by forceps with or without fragmentation in the remaining 23. Whereas the treatment was successful in 36 children (87.8%), it was unsuccessful in 5 (12.2%) secondary to bleeding and mucosal injury in 3 children (7%; 1 middle- and 2 upper-ureteral stones) and severe ureteral stenosis with kinking in 2 (4.8%; 1 middle- and 1 upper-ureteral stone) children. In two other cases, although the fragments in the upper portion of the ureter could be reached with the ureteroscope, the stones migrated into the renal collecting system during pneumatic lithotripsy and were treated successfully with subsequent SWL (4.8%). At the end of the procedure, a 4.8F Double-J stent was left in place in 9 cases. There were no serious complications, and the children were not specifically evaluated for postoperative vesicoureteral reflux. Follow-up ranged from 1 to 36 months with an average duration of 22.4 months. CONCLUSION: With the aid of the experience gained in the adult population and careful instrumentation, we believe that, in skilled hands, rigid ureteroscopy can be applied in a safe and efficient manner for stones located in different portions of the pediatric ureter. 相似文献
