Short-term (1 or 2 post-operative days) ureteral catheter stenting after transurethral uretero-lithotomy (TUL) to avoid flank pain due to transient ureteral edema is described. Patients who underwent TUL for middle or distal ureteral stones with a rigid ureteroscope without complications during the procedures were the candidates for short-term ureteral stenting. An end-hole ureteral catheter, used to insert a guide wire during TUL, were used for stenting. The tip of the catheter was located near the renal pelvis and the other end was introduced outside through the urethra with a 14 F urethral catheter. The stent and catheter were removed on post-operative day 1 or 2. For the 18 patients treated using this method, the time of analgesic use after stent removal was 0.6±0.8, indicating a sufficient duration of stenting. Short-term ureteral catheter stenting is a cheap and easy way for post-operative management for uncomplicated TUL. 相似文献

From July 1985 to June 1987, 303 patients with ureteral stones were treated by either extracorporeal shock-wave lithotripsy (ESWL) or transurethral ureterolithotripsy (TUL). The ureteral stones were classified into two groups, upper and lower ureteral stones. The upper ureteral stone was defined as a stone located above the pelvic brim in radiological examinations. ESWL was performed using a Dornier lithotriptor HM-3. For TUL, following the insertion of a guide wire and dilatation of the intramural ureter by ureteral bougie, a ureteroscope was introduced into the ureter. The success rate included both patients who became stone free and patients whose stones were disintegrated into less than 4 mm. The success rate of ESWL for upper ureteral stones was 90%, and 8.5% were treated subsequently by TUL. The success rate of TUL for upper ureteral stones was 42%, and the remaining required another session of TUL or another procedure, mainly ESWL. On the other hand, the success rate of TUL for lower ureteral stones was 71%, and the remainder also required another session of TUL or another procedure, mainly ESWL. The efficacy of TUL for stone street was comparably low by the evaluation done at 5 days after the procedure. However, almost all patients with stone street, which had developed after ESWL treatment, became stone free several weeks after TUL and insertion of a stent catheter. Major complications or side effects for ESWL were fever of more than 37.5 degrees C (7.5%) and pain attacks (8.9%).(ABSTRACT TRUNCATED AT 250 WORDS) 相似文献

During the 39 months since the introduction of transurethral lithotripsy (TUL) for the treatment of ureteral stones at our hospital in August 1985, TUL was performed a total of 200 times in 178 patients with ureteral stones. Among them, 111 patients had left ureteral stones and 65 had right ureteral stones, while 2 patients had ureteral stones in both sides. The stones were divided into upper ureteral stone (84 patients) and lower ureteral stone (94 patients) at above and below the iliac brim. 89% of the stones were less than 2 cm in diameter. Most of the patients were given lumbar anesthesia, and a guide wire was inserted into the ureter. The ureter was dilated with a ureteral bougie, and a 13F or 14F Storz ureteroscope was inserted. The stones were disintegrated by an ultrasound lithotripto and removed using forceps and a basket catheter. After the TUL procedure, a double J catheter was indwelled and removed within 5 days. The results were evaluated by DIP which was done 2 to 3 months after TUL. The success rate included residual stones less than 4 mm in diameter, as they could be spontaneously discharged. As a result, the success rate for upper ureteral stones was 53%, and it was higher for smaller stones. On the other hand, the success rate for lower ureteral stones was 85% and significantly higher. The main reasons for failure were the upper migration of the stones (60%) and inability to insert the ureteroscope up to the stone due to ureterostenosis and ureteral perforation (39%).(ABSTRACT TRUNCATED AT 250 WORDS) 相似文献

Between September 1993 and December 1996, 138 patients underwent transurethral ureterolithotripsy (TUL) either as primary treatment or as a second-line therapy after extracorporeal shock wave lithotripsy. In all patients, a semirigid 6.0 F ureteroscope was used. Lithotripsy was performed using a pulsed-dye laser. The overall success rate was 82.6%. The success rates according to the location of stones were as follows, 76.9% for stones in the upper ureter (U1), 96.0% for those in the midureter (U2), and 86.2% for those in the distal ureter (U3). In 68 patients treated with TUL as primary therapy, the success rate was 88.2% and efficiency quotient, which was modified for TUL was 0.75. Complications were rare: no ureteral perforations and no major bleeding occurred, but urosepsis developed in 2 patients. In conclusion, transurethral ureterolithotripsy using a small caliber ureteroscope with pulsed-dye laser is recommended as the primary treatment for mid- and distal ureteral stones, because of its superior success rate. In addition, for upper ureteral stones, laser tripsy is recommended as a helpful auxiliary procedure. 相似文献

By September 1988, we performed 58 ureterorenoscopies (52 for primary ureteral calculi, 3 for ureteral biopsy, 2 for ureteral stricture and 1 for ureteral foreign body) using a Ureteromat (Uromat Storz, West Germany). Continuous saline irrigation with the Ureteromat has obviated mechanical dilation of the ureteral orifice in 93.1% of the cases, which made this endoscopy as easy as the conventional cystourethroscopy. In 4 cases (6.9%), however, balloon dilation of the ureteral orifice was necessary for the passage of a rigid ureterorenoscope. Of 52 ureteral calculi, 37 were assigned for transurethral ureterolithotripsy (TUL), whereas transurethral ureterorenoscopy (TUURS) was indicated to flush the remaining 15 calculi up into renal pelvis for later extracorporeal shock wave lithotripsy. TUL was successful in 81.1% (30/37). The causes of failure were stone migration in 6 cases and ureteral avulsion by electrohydraulic lithotripsy necessitating open surgery in 1 case. The irrigation with the Ureteromat facilitated the manipulation of intraluminal ureteral lesions always under clear vision; by-passing the impacted stone with a guide wire and flushing-up of the calculi were successfully performed in 100%, in spite of the co-existing edematous and inflammatory mucosal changes. In 7 cases where ureteroscope could not be advanced well up to the lesion because of spasm in the iliac ureter, the irrigation pressure was transiently increased up to 200 mmHg to allow safe and easy dislodgement of impacted calculi under fluoroscopic guidance. This procedure was also effective to introduced a ureteral stent over a guide wire in 2 cases of ureteral stricture, which could not be achieved by conventional cystoscopic procedure. Immediate postoperative complications were fever in 8.6% and gross hematuria lasting for more than 4 days in 8.6%.(ABSTRACT TRUNCATED AT 250 WORDS) 相似文献

A Dornier MFL 5000, a new generation extracorporeal shock wave lithotripter, was installed in our hospital and the first Japanese clinical experience has been collected between July and November in 1989. We report our experience with the first 35 patients with 45 stones who were treated in 42 treatments using ESWL. We followed up 3 weeks. No invasive anesthesia was performed except 2 cases of epidural anesthesia. A double J catheter was installed in 2 patients, a ureteral catheter in 4 patients, and PNL was performed in 2 patients before ESWL. We did not use a PNL or a TUL in the postoperative treatment. In the 3 week followed up period, 29 patients (82.9%) were completely free from stone fragments. No serious complications were observed after ESWL. We conclude that the DORNIER MFL 5000 is effective for renal and ureteral stones without serious complications. 相似文献

ObjectiveTo compare intraoperative ureteral injuries in RIRS with UAS insertion with the rate of postoperative infections after RIRS without UAS insertion.Patients and methodsIn this randomized trial, patients who received an indication for RIRS between January 2017 and December 2017 were divided into two groups. Group A had no UAS insertion and Group B had UAS insertion. Post-Ureteroscopic Lesion Scale (PULS) grading was performed after UAS or flexible ureteroscope removal. Proximal, middle and distal ureteral lesions were evaluated and compared according to the PULS scale. Additionally, patients in both groups were followed postoperatively to assess any infective complication.ResultsThe evaluation comprised 181 patients, 89 for group A and 92 for group B. Overall stone-free rate, clinically insignificant residual fragments, and final stone-free rate were 41.4%, 53.5%, and 95%, respectively. There were 33 (37.1%) patients with ureteral lesions in group A while 42 (45.6%) patients had ureteral lesions in group B, with no significant difference. On the other hand, the overall presence of postoperative infection rate was much higher for Group A (37.1% vs 16.3% P = .03).ConclusionsUAS insertion does not result in a higher number of ureteral injuries. UAS insertion during RIRS allows a lower rate of postoperative infections.Clinical Trial Registration Number (ISRCTN registry number): 55546280. 相似文献

We report our experience with extracorporeal shock wave lithotripsy (ESWL) in the treatment of ureteral and cystine stones, which are known to be difficult to treat by this method. First, in order to determine the effectiveness of the ureteral catheter in the destruction of ureteral stones, we compared the clinical results of 121 patients treated without the catheter and 141 patients inserted with the catheter. There was no significant difference in the success rate between the two groups regardless of stone size, which indicates that the use of the ureteral catheter had no effect on the outcome of treatment. We then studied the clinical results of impacted ureteral stones which are especially difficult to destroy. Excretory urography was performed to non-invasively diagnose these stones, and those without visualization in the ureter below the stone were diagnosed as impacted stones and treated by ESWL without the ureteral catheter. Among the stones with a diameter of 1 to 2 cm, the success rate was significantly lower in impacted stones compared to non-impacted stone. These findings suggest that ESWL treatment without the ureteral catheter may be effective for ureteral stones with a diameter of less than 1 cm and non-impacted stones with a diameter of 1 to 2 cm, while combination therapy with other methods such as TUL may be better for other stones. We also performed ESWL on 6 patients with renal stones and 2 patients with ureteral stones which were cystine stones. Renal stones required an average 4.1 treatment with an average of 1,875 shocks per treatment, and ureteral stones required 1.5 treatment with an average of 1,833 shocks.(ABSTRACT TRUNCATED AT 250 WORDS) 相似文献
