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 equipments available and the expertise of the operator, we recommend URS as the optimal treatment for distal ureteral calculi.

METHOD: Total laparoscopic hysterectomy was performed in 2 patients who had undergone liver transplantation, one for adenomyosis and the other for hysteromyoma. RESULTS: It was safe to create a pneumoperitoneum through the umbilical skinfold even though mild adhesion in the pelvic cavity occurred in one patient. The operative times were 95 and 90 minutes, with blood loss of about 100 and 60 ml, respectively. Oral intake, flatus passage, and ambulation recovered within a day, after the operation. No significant changes in liver function were observed except complication of diarrhea caused by Candida albicans in one patient. CONCLUSIONS: The result of the two patients suggest that total laparoscopic hysterectomy is a safe and effective surgical approach for patients who have undergone liver transplantation.展开更多

Methods Sickle parenchyma incision was used to remove stones in 37 patients with complex staghorn renal calculi. The procedure was as follows; the kidney was disected free and the pelvis within sinus renalis was isolated. Two of botton style sutures were made on the renal parenchyma with 2-0 plain catgut along mid-lower 1 /3 of the dorsal surface of kidney free of vessels (Brodie’ s line) from the renal posterior lib to the plane of lower major calyx. The renal parenchyma was opened. Then, the incision was developed from the plane of lower major calyx through the middle major calyx to the plane of upper major calyx. The shape of this incision appeared like a sickle. The renal parenchyma and each calyx along this incision were opened and so was all the stones could then be easily removed. The calyces could well be observed. Results The calculi were completely removed in all the 37 cases. 21展开更多

Methods Eighty-seven patients with renal tuberculosis were retrospectively reviewed; their diagnosis was established by standard microbiological and histological techniques. Results Atypical RT was diagnosed by various examinations, including urinary analysis, polymerase chain reaction of tuberculosis ( PCR-TB), ultrasonography, intravenous urography ( IVU), and computerized tomography (CT). Treatment consisted of antituberculous chemotherapy in all patients, in combination with nephrectomy (62. 5 %) or enterocytoplasty (4. 6%). Conclusion The differential diagnosis of RT should be emphasized, especially for atypical RT, provided a much more specific diagnosis in clinical suspicion of RT. IVU can not be regarded as a specific examination for RT. Computerised tomography (CT) can be used for early diagnosis of RT. Surgery for TR is still ablative. 5 refs.展开更多
