Objective: To estimate the efficacy of sequential treatment of bladder endometriosis (BE) of the vesicoureteric junction using transurethral resection (TUR) and hormonal therapy. Design: Case report. Setting: Private multispecialty hospital. Patient: A multiparous woman presented with perimenstrual lower urinary tract symptoms, cyclic chronic pelvic pain, and left loin pain. Intervention[s]: Ultrasonography revealed marked left renal dilatation. Computed tomography confirmed the presence of a bladder mass. A diagnostic cystoscopy revealed compression of the left vesicoureteral junction. Complete TUR BE with release of chocolate material during resection, followed by ureteric double J stent insertion for 3 months, was performed. Histopathology confirmed the diagnosis of BE, followed by adjuvant hormonal therapy (dienogest) for 3 months. Follow-up for about 2 years revealed complete relief of the symptoms without any recurrence. Main Outcome Measure[s]. Success and recurrence rates of sequential TUR and hormonal therapy of BE of the vesicoureteric junction. Result[s]. TUR BE followed by adjuvant hormonal therapy was very effective in eradicating BE of the vesicoureteric junction in a safe manner without recurrence on follow-up for 2 years. Conclusion[s]. BE of the vesicoureteric junction can be properly treated by sequential TUR and hormonal therapy without recurrence over a 2-year follow-up.

체외 충격파 쇄석술시 쇄석기종에 따라 각각 장단점이 있으며, 전 처치로 인한 여러 가지 부작용이 보고되고 있다. 이에 전자기식 ESWL시 하부결석환자에서 적합한 충격파의 강도를 찾아보고, C-arm의 총 가동시간을 측정해 보았다. 본 연구는 2014년 1월부터 6월까지 경북지역 일개시의 C대학병원에서 전 처치를 시행하지 않고 ESWL을 받은 65명의 환자를 대상으로 하였다. 성비는 남자가 48명, 여자가 17명으로 남자가 더 많았으며, 연령은 50대가 가장 많았다. 하부요로결석의 발생은 왼쪽이 더 많았으며, 결석의 크기는 5mm 이하가 39명으로 가장 많았다. 적합한 충격강도는 1의 강도이며 통증을 호소하는 경우 C의 강도로 전환하여 충격을 가할 수 있다. 또한 C-arm의 총 가동시간은 $241.73{\pm}30.37$초로 나타났으며, 이것은 하부요로결석의 크기와 유의한 차이를 보였다(p<0.05). 따라서, ESWL시 전처치를 시행하지 않고 시술을 할 경우 요관 결석의 부위에 따라 적합한 충격강도와 충격빈도의 기준이 필요로 하며, C-arm 총 가동시간도 요관 결석의 발생부위에 따라 방사선으로 인한 피폭을 최소화하기 위한 총 가동시간에 대한 기준이 필요할 것으로 사료된다.

Urodynamics describes a collection of tests designed to evaluate lower urinary tract function and can be performed using retrograde filling of the bladder within a room. In this study, we designed and calibrated the potable urodynamics monitoring system using DSP chip (TMS320VC33, Texas Instrument$^{TM}$, U.S.) and collected pressure and EMG using calibration kit (DPT9022K0122, Medtronics$^{TM}$, U.S.). This system can make patients more comportable and monitor spontaneous urination during daily life.

In this study, we designed and calibrated the potable urodynamics monitoring system using DSP chip (TMS320VC33, Texas InstrumentTM, U.S.) and obtained signals of bladder(Pves) and bladder neck pressure(Pneck) and EMG using calibration kit (DPT9022K0122, MedtronicsTM, U.s,). This system monitor spontaneous urination during daily life and can make patients more comportable.

A study was carried on histopathology of LUTD. Based on this study, it was noted that a plural number of factors and some genetic mechanisms are participating in onset of this disease, which should have to be studied further in future in omnidirections.

Chronic kidney disease, the presence of structural and functional abnormalities in the kidneys, is associated with a lower quality of life and increased morbidity and mortality in children. Genetic etiologies account for a substantial proportion of pediatric chronic kidney disease. With recent advances in genetic testing techniques, an increasing number of genetic causes of kidney disease continue to be found. Genetic testing is recommended in children with steroid-resistant nephrotic syndrome, congenital malformations of the kidney and urinary tract, cystic disease, or kidney disease with extrarenal manifestations. Diagnostic yields differ according to the category of clinical diagnosis and the choice of test. Here, we review the characteristics of genetic testing modalities and the implications of genetic testing in clinical genetic diagnostics.

We present the characteristic plain radiographic and intravenous urographic (IVU) findings of calculus formed over a hair. A 66-year-old man who had been quadriplegic for 40 years because of vertebral injury was admitted for further evaluation of frequent urinary tract infection. Plain radiography showed a linear, serpiginous calcification in the lower abdomen, and IVU revealed a round filling defect with linear radiopacity in the bladder, suggesting calculus. The gross appearance of the stone after extraction demonstrated that calcification had formed over a hair.

요석증은 비뇨기과에서 흔히 관찰되는 질환으로서 30∼50대에 많이 발생하고, 남자가 여자보다 발생빈도가 높고, 좌측보다는 우측이 많으며, 문화가 발달한 나라에서는 상부요로 결석이 많으나 후진국에서는 하부요로 결석이 많다. 결석성분은 수산칼슘, 인산칼슘, 인산마그네슘암모늄, 요산, 시스틴 결석과 그들의 혼합결석으로 분류된다. 병태 생리학에 따르면, 결석의 발생원인은 요중의 무기질 농도가 과포화 상태가 되면 결정체핵이 생성된다는 과포화/결정체설, 기질관여설, 억제물질의 결핍설, 에피택시설 등이 있고, 상피소체기능항진중, 과칼슘뇨증, 과요산뇨증, 과수산뇨증, 시스틴뇨증 외에도 원위세뇨관 산증, 과비타민 D증, 소화기계 질환이 통계적으로 유의성 있게 관여된다는 것이다. 본 연구에서는 미란성 위염 환자 K43에서 화학분석법, 적외선 흡수 분석법, image analysis법을 사용하여 재발성 상부요로 결석성분을 분석한 결과 제2 수산칼슘과 인산칼슘의 혼합결석으로 확인되었고, 혈액화학 검사와 요 검사 등 임상검사 성적은 정상치를 유지하고 있었다. 따라서 K43의 재발성 요로결석은 보고된 생성원인이나 인자들에 대한 통계수치와는 연관성이 없었으며 미란성 위염으로부터 영향을 받았다는 증거도 없었다.

Purpose: The 5 alpha reductase inhibitor (5ARI) reduces the size of the prostate and alleviates lower urinary tract symptoms. After stopping 5ARI, the prostate quickly recovers to its pre-medication size. The purpose of this study was to investigate the factors affecting the restoration of prostate size after 5ARI discontinuation. Materials and Methods: Between March 2009 and May 2017, patients who visited an outpatient clinic and were diagnosed with benign prostatic hyperplasia were selected and start 5ARI medication. After 6 months of medication, the patients stopped medication for 1 year. Meanwhile, we measured the prostate volumes of patients 3 times (before and after medication, after discontinuation) and divide the patients into 3 groups (maintained, intermediate, and restored) with recovered prostate volume ratio. After classification, we investigated the relationship between the variable factors (age, serum prostate-specific antigen, initial volume, reduced volume after medication) between groups. Results: Among the 147 selected patients, the mean age and plasma PSA level were $61.6{\pm}7.9$ and $0.8{\pm}0.6$, respectively. The mean initial prostate volume was $32.3{\pm}4.2ml$, which reduced to $23.2{\pm}3.2ml$ after medication. After one year of discontinuation, the mean volume was $31.4{\pm}6.4ml$, with restoration to 101.5% of the reduced size. We noticed a tendency that patients with faster prostate volume recovery were generally older than those with slower recovery; however, this was not statistically significant. Other factors showed no relationship with prostate recovery. Conclusions: When using 5ARI in elderly patients, continuous treatment seems better than intermittent treatment. If discontinuation is needed, short term follow-up is recommended.
