A Case of Renal revascularization using Aortorenal Saphenous Vein Bypass Grafting in Renovascular Hypertension / 대한비뇨기과학회지

Renovascular hypertension is the leading cause of surgically curable arterial hypertension. With the marked advancement in the technique of vascular surgery, renal revascularization is preferred to nephrectomy. It is used for the recovery of impaired function or the prevention of renal failure and the control of hypertension. We report a case of renovascular hypertension with the nonfunction of the left kidney due to complete renal artery obstruction, treated successfully with an aortorenal bypass graft.

Prophylactic Effect of Mitomycin C and Bacillus Calmette-Guerin in Stage T1 of the Superficial Bladder Cancer / 대한비뇨기과학회지

We compared the efficacy and toxicity of mitomycin C and Bacillus Calmette-Guerin (BCG) intravesical instillation in 86 patients with stage T1 of the superficial bladder tumor. Of them, 34 patients were received mitomycin C (40 mg/40 ml sodium chloride, once a week for 8 weeks) and 26 patients were received BCG (120 mg/50 ml sodium chlorids, once a week for 6 weeks) after transurethrat resection of bladder tumor and 24 patients (control) underwent transurethral resection alone. The mean follow up period was 24.8 months in control group, 26.8 months in mitomycin C group and 25.7 months in BCG group. The mean time to recur was 11.3 months in control group, 11.5 months in mitomcyin C group and 15.9 in BCG group but there was no significant difference among each groups (p>0.05). The overall recurrence rate was 34.6% in BCG group compared with 70.5% in mitomycin C group and 75.0% in control group, showing significant difference (p<0.05). Side effects were more common after BCG instillation than mitomycin C instillation. The most common side effect after BCG instillation was hematuria in 14 patients (53.8%). That of mitomycin C was cystitis in 10 patients (29.4%). Our study suggests that the prophylactic efficacy of BCG was significantly superior to that of mitomycin C, but there was no significant superiority regarding prophylactic effect of reduced mean time to recur in stage T1 bladder cancer patients. Additionally, further follow up studies were needed in mitomycln C.

Clinical Experience of Domestic SDS-2 Extracorporeal Shock Wave Lithotriptor (ESWL) for 315 Urinary Calculi / 대한비뇨기과학회지

Extracorporeal shock wave lithotripsy monotheraphy was performed in 315 urinary stones from 278 patients with the Domestic SDS-2 lithotriptor using C-arm fluoroscopy between December 1991 and December 1994. Of 315 cases, renal stones were 150 cases(47.6%) and ureteral stones 165 cases(36.1%). No regional or general anesthesia was required but parenteral or oral analgesics were required in some patients. Among 315 cases who completed extracorporeal shock wave lithotripsy, the overall success rate of treatment was 90.5% with 92.4% in 5-9 mm, 94.8% in 10-19 mm, 89.7% in 20-29 mm and 61.5% over 30 mm or staghorn stones. Post lithotripsy complications were transient gross hematuria in 17.1%, renal colic in 11.4%, steinstrasse in 4.8%, petechia in 2.9% and fever in 1.9% and these complications were controlled with conservative treatment or repeated session of extracorporeal shock wave lothotropsy, percutaneous nephrodtomy, Double-J stent insertion or ureterolithotomy. We suggest that extracorporeal shock wave lithotripsy monotheraphy with the Domestic SDS-2 lithotriptor was considered to be effective and safe procedure for the initial treatment of urinary stones.
