To determine the optional and objective criteria for choosing the appropriate treatment modality or ureteral calculi. we reviewed 210 patients (215 ureteral calculi) initially treated with expectation (78 calculi), ESWL (82 calculi). ureteroscopic removal (31 calculi). stone basket (7 calculi) and surgery (17 calculi) and the results of each treatment were compared. N 78 calculi treated with expectation 58 (74.4% ) passed spontaneously. The duration of 50% and 75% cumulative spontaneous passage (CSP) of proximal ureteral calculi (<6 mm) were 3 weeks and l3 weeks, whereas the duration of 25% CSP of proximal ureteral calculi (> or =6 mm) were 5 weeks (p=0.0087). The duration of 50% and 75% CSP of distal ureteral calculi (<7 mm) were S weeks and S weeks. whereas the duration of 25% and 50% CSP of distal ureteral calculi (> or =7 mm) were 4 weeks and 11 weeks (p=0.01 75). The overall success rate of ESWL was 88.5% and the success rates of upper. middle and lower ureteral calculi were 92.2%. 70.6% and 94.7%. The duration of passage of calculi fragmented by ESWL was 1 to 16 weeks (mean: 4 wks). The overall success rate of ureteroscopic removal was 87.5% and the rate increased to 93.1% when only lower ureteral calculi were included. Stone basket was successful in 4 calculi out of 7. In conclusion, it is preferable to treat the proximal ureteral calculi smaller than 6mm and distal calculi smaller than 7mm with expectation until 3 months and 5 weeks, respectively. Otherwise ESWL is appropriate for proximal ureteral calculi and ureteroscopic removal for lower ureteral calculi. Although advanced technology for the management of ureteral calculi has been developed, traditional therapy has the proper role in contemporary practice.

During 5 years (1994-1998), 28 patients with renal and ureteral stones in solitary kidney were operated at the surgical department of §µ N½ng hospital, including congenital solitary kidney: 3 patients (10.7%). Acquired solitary kidney: 1 patient (3.5%). Functional solitary kidney: 24 patients (85.7%). Among them: renal stone: 27 patients (96.4%), Staghorn stone: 14 patients (50%). Pyelotomy and nephrostomy account for 68% of cases, associated with positive drainage of pelvis giving favourable results: No need for blood transfusion: 24 patients (86%). Residual stones: 1 patient (3.5%). Post-operative bleeding: 2 patients (7.0%). Short-term follow up: Good (78.6%), medium (14.0%), Bad (7.0%)

A prospective study was carried out on 17 patients with upper ureteral calculus treated by retroperitoneal laparoscopy in Viet Duc Hospital from Nov 2004 to Apr 2005. Results: The blood loss was usually not much (20-100 ml). It was difficult to remove calculi due to they moved up to kidney, it must enlarge the incision. There were two cases of peritoneum perforations during the operation that had been sutured. In postoperative period, patients were stable, there were no complications besides mild abdominal pain at the incision; 1 month after the operation, these patients well recovered. This procedure is superior to traditional open surgery with less complications, shorter of hospitalization stay, rapider recovery...

The ureterolithotomy was usually performed through a longitudinal incision of the ureter in the field of urology. Many complications caused by the longitudinal incision of the ureter were very well known. Gil-Vernet has emphasized transverse incision of the ureteral calculi from his satisfactory results on 73 operations. Transverse ureterolithotomy on 7 cases were performed. Postoperative course of all cases was uneventful. This method and comparison to the longitudinal incision should be considered.

Ureteroscopy is the newer procedure for the treatment of ureteral calculi, and now established the first treatment of ureteral calculi. A study of 42 cases of ureteroscopic removal of stones was performed. Removal of stones was successful in 29 of 42 attempts(69 percent). 26 of 31 patients with lower ureteral calculi (84 percent) and 26 of 35 patients with calculi smaller than 1 cm(74 percent) underwent successful removal. There were no significant complications during or after the procedure. In conclusion, ureteroscopic removal of stones can be the first choice of treatment of ureteral calculi, and proper technique, surgical skill and prudence are essential prerequisites and increase experience will improve the success rate.

PURPOSE: To determine the usefulness of transrectal ultrasound (TRUS) and to compare TRUS with intravenousurography (IVU) in the evaluation of distal ureteral calculi. MATERIALS AND METHODS: TRUS and IVU were perfomed in 24 patients with distal ureteral calculi. Using TRUS, we evaluated the presence and size of calculus, type of ureteral jet at the affected site and diameter of ureter proximal to calculus, and using IVU evaluated the presence and size of calculus, degree of ureteral obstruction, and degree of hydroureter. TRUS and IVU findings, were compared. RESULTS: In each patient, TRUS detected calculus of the distal ureter ; in only 18cases (75%),were the calculi demonstrated with IVU. In 18 cases where calculi were detected by both modalities, average calculus size was 4.5 X 3.0mm (longest and shortest dimensions) by IVU, and 6.1 X 3.7 mm by TRUS. Betwee TRUS and IVU(p<0.05) there was a statistically significant difference in the longest dimension of calculi. Color Doppler imaging revealed three patterns of ureteral jets in TRUS : normal periodic jet (7 cases) ; continuous low-levelflow (8 cases) ; and no detectable jet (9 cases). There was a positive correlation between type of ureteral jetson TRUS and between degree of obstruction on IVU (r=0.59, p<0.05). There was, however, no significant correlation between diameter of ureter proximal to calculus on TRUS and degree of hydroureter on IVU (r=0.32, p>0.05). CONCLUSION: TRUS appears to be a useful adjunctive method for the evaluation of distal ureteral calculus.

A gentle manipulation and a thorough premanipulative checking of urological instruments are very important to prevent accidents occurring during urological instrumentation. The case of a 40 year old ale with a left ureteral calculi in whom a Johnson Stone Disloger successfully caught the stone but in whom repeated attempts at withdrawal of the dislodger were unsuccessful is reported. An open ureterolithotomy was required to remove the stone which was tightly packed in the islodger's basket. This case demonstrates that despite gentle manipulation and a thorough premanipulative checking of the instrument, accidents in instrumentation can occur.

From 1999 to 2004, 6 pregnant women with lasting symptoms of ureteral calculi underwent therapeutic ureteroscopy in the Hospital of Hanoi Post and Telecommunication. The length of gestation ranged from 3 to 28 weeks (median length is 9 weeks). The calculi were detected by ultrasonogrphy, however 1 patient by an X-ray plain film because she was unaware of her pregnancy. In 5 patients, the calculi were removed successfully. There was no complication. The outcome of gestation was satisfactory: the deliveries were normal in 5 patients. 1 patient was stone free and had elective termination unrelated to ureteroscopy. Conclusion: diagnosis and treatment of ureteral calculi in pregnant women is difficult because of some physiological and anatomical changes, and the need of ensuring mother and child's safety. Assessment of gestational development and damage of kidneys are needed for proper treatment
