We present a case of 15 months old male with Multilocular cystic nephroma (MLCN) which contains fibroblast, smooth muscles, skeletal muscles and well differentiated tubular structure in the septa without evidence of blastemal or embryonal elements. There is no evidence of metastasis and local recurrence after post-op 2 years.

From January 1988 to January 1996, 42 infants and children (44 renal units) had undergone surgical management to correct ureteropelvic junction obstruction. Median patient age was 8.5 years (range from 2 months to 17 years) and 11 patients were less than 1 year old at operation. Of 44 renal units surgically managed, 30 were on the left side and 10 were right side. 2 patients had undergone bilateral surgical management. Presenting symptoms were febrile urinary tract infection in 14 cases, abdominal pain in 14 cases, abdominal mass in 5 cases, gross hematuria in 3 cases and 3 cases were detected prenatally. We used imaging antegrade pyelography (AGP) in 15 cases, additional retrograde pyelography (RGP) in 12 cases and both AGP and RGP were performed in 1 case. To correct ureteropelvic junction obstruction, we performed dismembered pyeloplasty in 33 renal units, ureterolysis in 2 renal units, ureterocalycostomy in 1 renal unit, endopyelotomy in 1 renal unit and nephrectomy in 7 renal units. To diverge the urinary flow, we used nephrostomy in 19 renal units, ureteral stenting in 6 renal units and both nephrostomy and ureteral stenting were used in 10 renal units. As postoperative complications, restenosis was developed in 5 renal units, delayed open in 5 renal units, urinary tract infection in 2 renal units and wound infection, prolonged urine leakage, ureteral stone in each 1 renal unit. Postoperative success rate in followed-up patients, who had undergone pyeloplasty, was 91.6%. The success rate in children, who was less than 1 year old, was 100% and in children, who was more than 1 year old, was 88.4%. Finally we suggest that the surgical correction is safe and proper method for ureteropelvic junction obstruction in children. Additionally early operation of ureteropelvic junction obstruction is recommendable.

Proper management of childhood and adolescent varicocele remains still controversial. In general, all methods for varicocele ablation for adults are available and include open surgical ligation, laparoscopic ligation, or percutaneous ablation. We evaluated the usefulness of percutaneous embolization of internal spermatic vein in boys with varicocele. Between February 1988 to May 1996, 48 boys of 53 varicoceles underwent percut aneous embolization. In 49 cases, the embolization were technically possible and in the other 4 cases, we could not access the internal spermatic vein because of vasospasm and venous abnormality. The results were successful in 40 cases (81.6%) and failed in 9 cases (18.4%), including 4 (8.2%) of persistent and 5 (10.2%) of recurred cases. There were no major complications except 3 cases of extravasation of contrast material. Percutaneous embolization may be recommended as a primary treatment for childhood and adolescent varicocele.

PURPOSE: To evaluate the hemodynamic status of varicocele, 99m Tc-RBC venography was performed in 29 varicocele patients and 10 normal controls from January to July 1996. MATERIALS AND METHODS: The mean age of varicocele patients was 23 years old and of normal controls was 27 years old. Among 29 varicocele patients, 26 had varicocele in left side and 3 had in both side. In unilateral varicocele group. 2 cases had grade I, 8 cases had grade II and 16 cases had grade III varicocele. In bilateral varicocele group, all had grade III in le% side and grade II varicocele in right side. RESULTS: The mean+/-SD of left to right radionuclide uptake ratio in pampiniform plexus during resting and Valsalva maneuver state was 1.01 +/-0.04:1 and 1.05+/-0.05:1 in normal control, 1.05+/-0.02:1 and 1.10:1 in varicocle grade I, 1.21+/-0.19:1 and 1.21 +/-0.12:1 in varicocele glade II, 1.60+/-0.63:1 and 1.27+/-0.18:1 in varicocele grade III, 1 18+/-0.06:1 and 1.26 in bilateral varicocele. As varicocele grade be higher, the mean left to right radionuclide uptake ratio be larger during resting and Valsalva maneuver state. CONCLUSIONS: 99mTc-RBC venography can quantify the hemodynamic state of varicocele so we suggest that it is useful as a method of diagnosis and follow up in varicocele patient.

PURPOSE: This study was performed to investigate whether the free to total PSA ratio(F/T PSA ratio) offers a better discriminant for the detection of patient with prostatic cancer(CaP) and those with benign prostatic hyperplasia(BPH) than serum total PSA alone. MATERIALS AND METHODS: From September 1996 to February 1999, free and total PSA levels were measured on frozen sera samples of 154 men with BPH and 46 with CaP using immunoradiometric assay. RESULTS: In all subjects, the mean total PSA was significantly higher in CaP group(72.59+/-66.58ng/ml) than BPH group(3.12+/-4.10ng/ml). The mean PSAD was significantly higher in CaP group(1.64+/-1.86) than BPH group(0.08+/-0.01). The mean F/T PSA ratio was significantly lower in CaP group(0.19+/-0.07) than BPH group(0.30+/-0.13). Among 41 subjects whose total PSA were between 4-20ng/ml, the mean PSAD was significantly higher in CaP group(0.37+/-0.16) than BPH group(0.17+/-0.07), but the mean F/T PSA ratio was not significantly different between CaP(0.19+/-0.10) and BPH group(0.25+/-0.13). By comparing the sensitivity and specificity of total PSA alone, PSAD and F/T PSA ratio on receiver operating characteristic(ROC) curve in all subjects and subjects with total PSA between 4-20ng/ml, F/T PSA ratio had no superiority than total PSA alone and PSAD for. discrimination between CaP and BPH. CONCLUSIONS: We suggest that the F/T PSA ratio is not superior to total PSA alone and PSAD in the detection of prostatic cancer, and further evaluation of the usefulness of F/T PSA ratio should be required.

BACKGROUND AND OBJECTIVES: The pathological findings of Non-Q wave myocardial infarction(NQMI) on ECG did not always correspond to subendocardial infarction(SEMI). The purpose of this study was to evaluate the diagnostic validity of ECG for SEMI by myocardial contrast echocardiography (MCE) in the patients with acute myocardial infarction(AMI). MATERIALS AND METHODS: The study population was 84 patients who underwent MCE under the diagnosis of AMI. MCE was performed by intracoronary injection of sonicated Hexabrix into the infarct related artery and SEMI was diagnosed by inspecting endocardial defect with epicardial enhancement on MCE. RESULTS: (1) Among 19 NQMI cases, 7 cases showed SEMI with MCE score 0.5, 11 cases with score 1, and 1 case with score 0. Among 65 Q-wave MI(QMI) cases, only 5 cases showed SEMI. (2) 7 cases who had NQMI with SEMI showed LV wall motion recovery at follow-up echocardiography except 1 case. Whereas, of 5 QMI cases who had SEMI, only 1 case improve LV wall motion. CONCLUSION: NQMI on ECG does not always imply SEMI on MCE, but the absence of pathologic Q wave in the patients with SEMI is thought to be a predictive factor of the recovery of LV wall motion.
