요도 결석은 매우 드믄 질환으로 보고된 증례가 많지 않으며, 대부분 요도 협착이나 요도 게실이 있는 남성에게서 대게 발생한다. 이에 우리는 20년 전 자동차 사고로 인한 척수 손상 후 하반신 마비가 발생한 42세 남성에서 발견된 거대 요로 결석 증례를 보고하고자 한다. 낮 동안에 다원적 증상을 가지고 있고, 고환 밑으로 종물이 만져지며 혈뇨 및 배뇨시 발생하는 통증을 보이면서 최근에는 소변이 전혀 나오지 않는 증상으로 응급실에 내원하여 비뇨기과 협진이 의뢰되었다. 고환 종물의 성상을 확인하기 위해 복부와 골반 컴퓨터 단층 촬영(CT)이 시행되었다. 검사 결과 종양은 관찰되지 않았다. 하지만, 요도 결석이 확인되었다. 우선적으로 요도성형술을 시행하여 방광루를 제거하였으며, 이후 요로 결석은 제거되었다. 2주 후에 요도조형술을 시행하였고 특이사항이 없음을 확인 후 소변줄을 제거하였다. 현재는 배뇨에 대한 특별한 문제는 없는 상태이다. 거대 요도 결석은 때때로 종양과 감별이 필요하며, 크기와 위치에 따라 치료법이 달라질 수 있어 좀 더 면밀한 검사가 필요하다.

Background: This study compared the following three endoscopic techniques used to treat bladder stones: transurethral cystoscope used with a pneumatic lithoclast or nephroscope used with a pneumatic lithoclast and nephroscope used with an ultrasonic lithoclast. Methods: Between January 2013 and May 2016, 107 patients with bladder stones underwent endoscopic treatment. Patients were classified into three groups based on the endoscopic techniques and energy modalities used in each group as: group 1 (transurethral stone removal using a cystoscope with pneumatic lithoclast), group 2 (transurethral stone removal using a nephroscope with pneumatic lithoclast), and group 3 (transurethral stone removal using a nephroscope with ultrasonic lithoclast). Baseline and perioperative data were retrospectively compared between three groups. Results: No statistically significant intergroup differences were observed in age, sex ratio, and stone size. A statistically significant intergroup difference was observed in the operation time-group 1, $71.3{\pm}46.6min$; group 2, $33.0{\pm}13.7min$; and group 3, $24.6{\pm}8.0min$. All patients showed complete stone clearance. The number of urethral entries was higher in group 1 than in the other groups. Significant complications did not occur in any patient. Conclusion: Nephroscopy scores over cystoscopy for the removal of bladder stones with respect to operation time. Ultrasonic lithoclast is a safe and efficacious modality that scores over a pneumatic lithoclast with respect to the operation time.

Hypospadias is a rare congenital malformation of the urethra reported in cattle. The urethral lumen of male indigenous Korean calf is open along the ventral aspect of the penis in the perineal region. Renal abscess and renal stone formation causing urinary tact infection has not been reported in hypospadia calves. The objective of this study was investigation for renal abscess and renal stone formation through autopsy. Histopathological examination and laboratory tests were performed. At autopsy, the pustules were formed on the right renal cortex, and the renal medulla abscess were formed on right and left part of the renal pelvis. Histopathological finding, this case was diagnosed as severe acute suppurative and necrotizing pyelonephritis, and severe chronic interstitial nephritis with fibrosis and moderate multifocal acute cystitis with edema. Milky exudate of the kidney has been identified as Actinomyces meyeri using the VITEK-2 system for identification of bacteria, and the stone has been identified as carbonate apatite using FT-IR system for quantification analysis. This case report describe the hypospadias complicated with urinary tract infection due to carbonate apatite stones and Actinomyces meyeri.

Background: Persistent uroliths after a cystotomy in dogs are a common cause of surgical failure. Objectives: This study examined the following: the success rate of retrograde urohydropropulsion in male dogs using non-enhanced computed tomography (CT), whether the CT mean beam attenuation values in Hounsfield Units (mHU) measured in vivo could predict the urolithiasis composition and whether the selected reconstruction kernel may influence the measured mHU. Methods: All dogs and cats that presented with lower urinary tract uroliths and had a non-enhanced CT preceding surgery were included. In male dogs, CT was performed after retrograde urohydropropulsion to detect the remaining urethral calculi. The percentage and location of persistent calculi were recorded. The images were reconstructed using three kernels, from smooth to ultrasharp, and the calculi mHU were measured. Results: Sixty-five patients were included in the study. The success rate of retrograde urohydropropulsion in the 45 male dogs was 55.6% and 86.7% at the first and second attempts, respectively. The predominant components of the calculi were cystine (20), struvite (15), calcium oxalate (8), and urate (7). The convolution kernel influenced the mHU values (p < 0.05). The difference in mHU regarding the calculus composition was better assessed using the smoother kernel. A mHU greater than 1,000 HU was predictive of calcium oxalate calculi. Conclusions: Non-enhanced CT is useful for controlling the success of retrograde urohydropropulsion. The mHU could allow a prediction of the calculus composition, particularly for calcium oxalate, which may help determine the therapeutic strategy.

The effectiveness of Cefoperazone in the treatment of urinary tract infection was evaluated in the Department of Urology, St. Mary's hospital from December 1. 1979 to April 30. 1980. In this studies, the cusative organisms were divided into 2 groups; 1) Single form. E. coli (8), Staphylococcus aureus(7), Proteus vulgaris (4), P. morganii(3), S. epidermis (1), Enterococcus(1), Klebsiella (2), N. gonococcus(1). 2) Mixed from: Proteus+E. coli(4), E. coli+other(1), Pseudomonas+Enterococcus(1), Klebsiella+other(1). Effectiveness on urological diseases. 1) Neurogenic bladder: Results were excellent in 3 cases, good in 4 cases and negative effect in 4 cases. 2) Non-gonococcal urethritis: In this group, the therapeutic results were favorable in 88.9% of all cases. (Excellent in 2, Fail in1) 3) Pyelonephritis: All(4 cases) were excellent. 4) Renal stone: Among the 4 cases of renal stone, only one case was responded to cefoperazone. 5) Two cases of urethral stricture, two cases of cystitis, one case of B.P.H. and one case of gonococcal urethritis were all excellent. No serious side effects were observed except slight dizziness in one case.
