The causes of pediatric urolithiasis are urinary tract infection as a result of urinary stasis, metabolic diseases and idiopathic origin. Geographically the incidence is higher in Asia than in any other parts of the world. Most recently, PNL was started to be applied not only for adult cases but also for pediatric urolithiasis. Our group was successful in treating two pediatric urolithiasis patients of 4 and 6 years of age by endourologic technique. In 4 year old male patient, renal stone and lower ureter stone were combined and severe hydronephrosis were present. PNL and URS were done simultaneously for this case. In 5 year old male patient, renal pelvis stone was treated by PNL. The compositions of the stones were calcium phosphate and calcium oxalate, respectively. The postoperative hospitalization was 5 days in both cases and they were discharged without any problem. In both cases, follow up IVP`s were done. We are reporting these two cases to two the successful treatment with adult endoscopes.

Intraperitoneal adminstration of radioisotopes is suggested to treat the metastatic ovarian cancer in the pertioneal cavity. Administering beta-emitting radioisotopes into the pertioneal cavity allows the maximum energy delivery to the cancerous cells of the pertioneal wall surface while sparing the normal cells located in deep site of the peritoneal wall. In this study, dose estimates of the peritoneal wall are provided to be used for prescribing the amount of 166Ho-chitosan complex administered. The 166Ho-chitosan complex diffused in the peritoneal fluid may attach to the peritoneal wall surface. The attachment fraction of 166Ho-chitosan complex to the peritoneal wall surface is obtained by simulating the ascites with Fischer rats. Both volume source in the peritoneal fluid and the surface source over the peritoneal wall surface are counted for the contribution to the peritoneal wall dose. The Monte Carlo code EGS4 is used to simulate the energy transfer of the beta particles emitted from 166Ho. A plane geometrical model of semi-infinite volume describes the peritoneal cavity and peritoneal wall. A semi-infinite plane of 10 micrometer in thickness at every 1 mm of depth in the peritoneal wall is taken as the target in dose estimation. Greater han 98 percents of attachment fraction has been observed from the experiments with Fischer rats. Given 1.3 microcurie/cm2 and 2.4 microcurie/ml of uniform activity density, absorbed dose is 123 Gy, 8.59 Gy, 3.00 Gy, 1.03 Gy, and 327 Gy at 0 mm, 1 mm, 2 mm, 3 mm, and 4 mm in depth to the peritoneal wall, respectively.

Development of the human colorectal cancer is associated with several distinct genetic abnormalities involving both dominant-acting oncogenes (K-ras, c-src) and tumor suppressor genes (APC, DCC, p53) which undergo inactivation or loss. In colorectal tumors, the common molecular alteration is localized in the 17p13 and 5q21 loci encoding the p53 and the APC gene, respectively. The identification of these genes may help the understanding of the pathogenesis of colorectal neoplasia. In order to determine whether the frequency of the genetic alterations varies with sex, age, tumor size, or site, including pathologic parameters, such as degree of differentiation, tumor stage, mucin component, lymphoid reaction, tumor invasion pattern, vein and nerve invasion, lymph node metastasis, and other parameters, such as disease-free survival, distant metastasis and patient outcome, the authors analyzed the loss of heterozygosity (LOH) of the APC and the p53 genes in paraffin-embedded specimens of 48 colorectal cancers by use of the polymerase chain reaction and restriction fragment length polymorphism. The results were as follows: the LOH affecting the APC was found in 15 out of 31 (48.4%) heterozygous patients, while the LOH of the p53 locus was observed in 11 out of 26 (42.3%) patients. Among 48 patients, the LOH at both the APC and the p53 loci was observed in five (10.4%) patient. No statistically significant associations were found between the LOH of the APC gene and the proposed parameters. The relationship between the LOH of the p53 and the histologic differentiation, lymphoid reaction was significant (P<0.05), but survival was not correlated. Statistically significant associations were found between overall survival of the colorectal cancer patients and distant metastasis, Astler-Coller stage, lymphoid reaction, invasion pattern, nerve invasion, vein invasion, lymph node metastasis, and disease free survival. The above results suggest that the LOH of the p53 genes could be involved in the progression of colorectal cancers. However, neither the LOH of the APC nor that of the p53 have significant association with survival of the colorectal cancer patients.

Alteration in the hormone level associated with menstrual cycle influences the interaction between the urethra and bladder as well as detrusor function, maybe due to the common embryological origin of lower female genital and urinary tract. We tried to investigate the effect of the menstrual cycle on cystometric diagnosis through this retrospective study. 60 women with regular menstruation were enrolled in this study. The study groups were divided into 2 groups, Group I was women whose symptoms were not influenced by the menstrual cycle, Group II was women whose symptoms were adversely affected premenstrually. The majority of normal cystometric diagnosis were made in the luteal phase (Group I: 42.9% vs 4.4%, p<0.05; Group II: 50.0% vs 22.2%, p<0.05). But diagnosis of genuine stress incontinence, detrusor instability, mixed genuine stress incontinence and detrusor instability were frequently made in the follicular phase of mentruation. Normal cystometric diagnosis in the group II were more commom than the group II ( 36.8% vs 19.7%, p<0.05 ). The results of this study reveal that the timing of cystometric evaluation may influence the the detection of a positive diagnosis. In patients whose symptom are influenced by their menstrual cycle, the luteal phase may not be the correct time to make an accurate diagnosis.

To evaluate the etiology and treatment of options in patients with hemospermia, we retrospectively reviewed 21 patients who had both transrectal ultrasound and MRI and have been followed for more than 6 months after initiation of treatment. Mean age was 40 years (range 20 - 50 years) with duration of infliction being 24 months (range 1 week to 16 years). Among the 14 patients with prostatic cyst, 9 patients underwent transurethral unroofing (TUUR) of cyst. All 9 patients were completely cured, but one patient developed postoperative epididymitis. Among the 6 patients with prostatitis, hemospermia was resolved in 4 patients after mean treatment of 12 weeks with antibiotics. In DES (Diethylstilbestrol) group, 50 % showed resolution of symptoms among 6 patients after 4 weeks of treatment, and two patients complained breast discomfort which were developed after medication. In conclusion, the antibiotic treatment is advisable in hemospermia patients with prostatitis. Prostatic cystic lesion is believed to be a factor in hemospermia, thus TUUR of cyst wall and removal of stone and hematoma in cyst can be a viable option.

The decision making for reimbursement has become more difficult than before because of the high cost innovative new technologies and limitation of healthcare resources. Evidence-based healthcare system has been introduced in Korea since 2007. Not infrequently, however, decision makers have been confronted with uncertainties caused by lack of information related to comparative effectiveness, real world outcomes, off-label drug use, combination therapy and cost-effectiveness. Under these circumstances, the decision making of whether or not to reimburse is inadequate because undesirable results may be induced. Managed entry agreement has been introduced globally. This kind of decision is conditional and linked with monitoring and following the results and adjusting the policy according to the results. Especially access with evidence development is a form of prospective data correction with conditional coverage in the case of existing uncertainties of effectiveness and safety. In Korea, there have been several examples including off-label drug use in oncologic drugs, new healthcare intervention and re-evaluation of existing drugs. Even though there has been some conflict and confusion because of inadequate systematization, it is strongly recommended to establish the conditional decision making system in Korea since this is a unique answer to manage the uncertainty in maintaining development of health science, keeping patients' right and using healthcare resources rationally.
