A case of testicular embryonal carcinoma developed in s cryptorchid testis is presented with a review of the literature. According to Campbell's series, the incidence of malignant cryptorchid testis was 11.6%. and his statistical evaluation was similar to Gilbert and Hamilton's series of 7,000 cases of testicular neoplasms where 840 tumors were developed in undescended testes(12%). Both authors agree that the chance of neoplastic development in a cryptorchid testis is approximately 48 times greater then that developing in a normally descended testis. Several cases of testicular tumor were reported sporadically in Korea, but malignant tumors in cryptorchism were rarely seen in the literatures Only two cases of malignant cryptorchid testis were already reported in Korea.

The adequate treatment of tibia fracture is one of the most difficult due to severe commiuntion, open wound, delayed union, angulation deformity and infection. We treated 38 fractures of the tibia by Interlocking intramedullary nail from Feb. 1983 to Mar. 1993. 35 cases of the tibia fracture were fresh, 13 cases of fracture were open. The other 3 cases were delayed union and nonunion. The Mean follow-up was 14.0 months. The results were as followings. 1. Of the 38 fractures, 37 fractures united and the mean union time was 18.7 weeks. 2. Interlocking intramedullary nail could be used to the majority of fractures of the proximal & distal tibia shaft. fractures. 3. The Im erlocking nail had rigid rotational stability and was appropriate for the treatment in severe unstable fractures, commninution and open-with bone loss. 4. Delayed union or nonunion was a good indication for intramedullary nailling. 5. The major-complication were valgus deformity of 2 cases, varus deformity of 1 case, 1 case deep infection. 6. Interlocking intramedullary nailing provided rigid fixation of . fracture and then made early joint motion exercise and ambulation.

We treated 160 patients with ureteral stones using extracorporeal shock wave lithotripsy (Siemens Lithostar, Germany) and evaluated many factors which influence the results of ESWL such as stone size, location, degree of ureteral obstruction. duration of impaction and adjuvant procedure. Our results showed that. in case of large stones (more than 1 cm in diameter), mid-ureteral stones, long-standing impacted stones or in-situ treatment, the success rates of ESWL were relatively poor. Therefore in cases accompanying the above-mentioned factors, in is necestary to recognize that the patients may be required to repeat ESWL. The results also suggest that the use of an ureteral catheter or stent may contribute to a slightly higher success rate. But we prefer in-situ extracorporeal shock wave lithotripsy to an ureteral stent because it is an invasive procedure.

A full understanding of the potential anatomical variations of the renal veins and its branches is imperative for donor nephrectomies. Preoperative renal angiography is the most important study to evaluate renal vascular anatomy. By this technique. the renal arteries are well visualized. but it is almost impossible to obtain the exact informations of the renal veins and its branches. To prevent extensive manipulation of the kidney by profuse bleeding. the exact information of the renal veins and its branches is very important. Based on intraoperative observation of 240 consecutive cases of donor nephrectomies. we observett. the common renal vein variants. Left renal veins usually had two branches; adrenal vein proximally and gonadal vein distally. Lumbar veins were identified in 112 cases(56.7%) Lumbar veins were connected to renal veins posteriorly near the draining site of gonadal veins. Therefore it is very important to dissect very carefully the posterior part of renal vein around the insertion of gonadal vein because of the existence of lumbar vein which might cause troublsome bleeding by accidental tearing. Especially when the cases of angulated renal veins were observed by renal angiography. the more attention will be required due to the strong possibility or the existence of lumbar vein.
