2 Cases of nephrotomy for removal of calculi in dog were referred to veterinary teaching hospital of Konkuk University. In case 1, a 5 year-old, castrated male Yorkshire Terrier dog was referred because of intermittent hematuria, pain in urination for one month. Hematologic and chemical examination showed mild increased BUN and CPK. Radiographic findings revealed radiopaque materials in the urinary bladder, urethra, and left kidney. Retrograde hydropropulsion was performed to move the calculi into the bladder, and cystotomy was done to remove calculi. Nephrotomy was performed to removal of the calculi from the left renal pelvis and calyx. After operation renal function were recovered and preserved. In case 2, a 5 year-old, neutral female Schnauzer dog was referred because of persistant vomiting, anorexia, and celialgia for 20 days. Hematologic and chemical examination showed stress leucogram, moderate azotemia, hypercalcemia, hyperphosphatemia, and increased ALP. Radiographic findings revealed enlargement of the left kidney and radiopaque materials in the both of the kidneys. On excretory urography, left kidney was no pyelogram. On ultrasonography, renal tissue was very thin and distended renal pelvis appeared. Nephrectomy of nonfunctional left kidney and nephrotomy for removal of calculi from the right renal pelvis and calyx were done. One week after operation, renal and hepatic functions were recovered. So, in cases of renal calculi, it is necessary that renal calculi are extracted actively as far as the patient's body condition endurable.

A Shihtzu (6-year-old, intact female) was referred to Konkuk University Teaching Animal Hospital for cystic calculus and hydronephrosis of right kiney. The dog was suspected to have ureteral rupture and peritonitis. Radiographic findings included cyctic calculi and right kidney enlargement. On ultrasonographic examination hyperechoic mass with severe acoustic shadowing was located in the right proximal ureter which was dilated. Hydronephrosis of the right kidney, right ureteral caculus and cytic calculus were confirmed by radiography and ultrasonography. Cystotomy for removal of calculus in the bladder and ureterotomy for removal of calculus in the right ureter were performed. Excretory urography (EU) performed one month after surgery revealed that the right ureter was homogeneously opacified and decreased to 3 to 6 mm in diameter. Surgical removal of ureteroliths was appropriate treatment for the ureteral and cystic calculi. The result suggests that ureterotomy is effective treament for the dilation and calculi of ureter.

Purpose: In developed countries, vesicovaginal fistula occur from various pelvic operations including total hysterectomy, leading to urinary leakage and incontinence. Although various methods have been proposed for adequate tissue coverage in fistula repair, the surgical treatment of is not simple and still controversial. We report a case of neobladder-vaginal fistula repair using modified Martius fat pad flap. Methods: A 62-year-old female patient underwent radical cystectomy with total abdominal hysterectomy and neobladder formation due to invasive bladder tumor 5 years ago. For 3 years following the operation, urine leakage was observed. Exploration demonstrated neobladder-vaginal fistula and primary repair including fistulectomy and direct closure was performed. Urinary incontinence relapsed 2 years after primary repair, and after demonstrating the recurrence of fistula on urography, repair of recurrent fistula was performed. After dissection of vagina and neobladder and closure of fistula by urologic surgeon, fibroadipose flap was elevated, rotated and advanced through the tunnel at vaginal sidewall, and interpositioned to the fistula site between neobladder and vagina. Results: There was no acute complication after the surgery and urethral catheter was extracted on the 8th day after the operation. During six month follow-up period after the operation, there is no clinical evidence of fistula recurrence. Conclusion: From our clinical experience and literature review, we think Martius fat pad flap is a useful technique in management of neobladder-vaginal fistula, for it provides enough vascularity, major epithelization surface and better lymphatic drainage, and also prevents overlapping of vesical, vaginal suture lines at the same time.

본 연구에서는 체질량 지수에 따라 각기 다른 관전압을 적용하여 비뇨기계 CT 검사 시 체질량 지수 적용의 유용성을 평가하고자 하였다. A그룹(n=38)은 체질량 지수가 25 이하이며 관전압 100 kVp로 검사하였고 B그룹(n=45)은 체질량 지수가 25 이상이며 관전압 120kVp로 검사하였다. C그룹(n=37)은 체질량 지수가 25 이하이며 관전압 120kVp로 검사하였다. 체질량 지수가 25 이하로 낮은 A그룹(100 kVp)과 C그룹(120kVp)의 두 그룹간 평균 선량의 차이는 $214.8mGy{\cdot}cm$의 차이를 나타내었으나 정성적 평가에서는 큰 차이가 없음을 확인할 수 있었으며 체질량 지수가 25이상인 환자군과 비교하여서는 오히려 좋은 결과를 확인할 수 있었다. 따라서 체질량 지수가 25 이하로 낮은 환자는 관전압을 100 kVp 로 낮추어 촬영하여도 영상의 질에는 부정적인 영향을 주지 않음을 알 수 있다.

교차성 신전위는 두 개의 신장이 정중선의 같은 편에 나란히 위치하는 선천성 신장병이다. 대개 기형은 오른쪽에 있고 융합되어 있는 경우가 융합되지 않는 경우의 8배에 달한다. 교차성 신전위는 흔한 질환은 아니지만, 영아에서 복부에 낭성 종물이 만져지고 반대편에 신장이 없는 경우에는 고려해 보아야 한다. 다낭 형성 이상을 동반한 융합된 교차성 신전위는 대부분 초음파로 진단되므로 진단을 위해 더 이상의 검사가 필요하지 않은 경우가 많다. 그러나 방사선 동위원소를 이용한 신주사로 교차성 신전위의 기능여부를 파악해야 하고, 배설성 방광요로조영술로 방광요관 역류나 신우요관이행부의 협착이 있는지 확인해야 한다. 다낭 형성 이상을 동반한 융합된 교차성 신전위에 대한 연구는 거의 없는 실정으로 저자들은 발열, 복통을 주소로 내원한 3세 남아에서 초음파를 시행하여 다낭 형성 이상을 동반한 융합된 교차성 신전위 1례를 경험하였기에 보고하는 바이다.

A 10 days old male infant with congenital megacalyces and megaureter, diagnosed by prenatal ultrasonographic screening, underwent Tc-99m DTPA renal scan for evaluation of urinary tract patency, Tc-99m DMSA scan for evaluation of renal cortical damage. He also underwent intravenous urography(IVU) and renal ultrasonography. Tc-99m DTPA renal scan demonstrates intense tracer accumulation in enlarged both renal pelvocalyses and ureters, which rapidly washout without diuretics administration. Tc-99m DMSA renal cortical scan shows no remarkable photon defect in both renal cortices and visible tracer uptake in both megaureter areas. Ultasonographic and IVU studios show enlarged both renal calyses and bullously dilated ureters, but no dilatation in renal pelvis. Follow up Tc-99m DTPA renal scan, peformed at one year later, also reveals intense tracer accumulation in enlarged both urinary tracts which rapidly washout without diuretics, and shows no significant change compare to the previous Tc-99m DTPA renal scan. Urinary tract obstruction and renal cortical damage can be easily evaluated with Tc-99m DTPA and Tc-99m DMSA scans in patiens with megacalyces and megaureter.

Background: Among women with haematuria, defining individuals under high risk for bladder cancer based on reproductive factors prior to cystoscopy would be of great benefit in the management of this condition. The aim of this study was to compare age and reproductive factors such as menopausal status, parity, age at first delivery and age at the last delivery between women who have haematuria with or without bladder cancer. Materials and Methods: A total of 463 patients underwent diagnostic cystoscopy in D$\ddot{u}$zce University Faculty of Medicine between 1 June 2008 and 1 June 2013. Female patients who presented with persistent microscopic or macroscopic haematuria and underwent standard evaluation for haematuria including urinalysis, urine culture, urine cytology, urinary tract imaging with excretory urography or computerized tomography with contrast enhancement and endoscopic evaluation of the urethra and bladder were included in this study. Exclusion criteria were tobacco use and high risk occupations for bladder cancer such as textile, dry cleaning, painting and etc. Forteen women had hematuria due to benign conditions, and 18 due to bladder cancer. Data were retrospectively retrieved from the medical records of Duzce University Hospital. Results: Patients with haematuria due to benign reasons did not significantly differ from patients who were found to have bladder cancer in terms of age (p=0.28), menopausal status (p=0.29), mean parity (p=0.38), being nulliparous (p=0.57), parity ${\geq}3$ (p=0.22), age ${\leq}18$ years at first delivery (p=1.00), age ${\geq}30$ years at last delivery (p=0.26), age ${\geq}35$ years at last delivery (p=0.23) and percentage of the patients with advanced age (${\geq}65$ years) (p=0.18). Conclusions: It is difficult to predict a high risk for developing bladder cancer in women with haematuria based solely on reproductive factors.
